SERVICE PROCESSING METHOD, AND USER EQUIPMENT

TECHNICAL FIELD

The present disclosure relates to the field of electronic terminal technologies, and in particular, to a service processing method, and user equipment.

BACKGROUND

An Internet Protocol (IP) multimedia subsystem (IMS) is a network system that provides voice and multimedia services based on an IP network. In an IMS network, as a calling number, an IP multimedia public identity (IMPU) may correspond to a user having at least one terminal, that is, one IMPU may correspond to multiple terminals, and one terminal may correspond to multiple IMPUs. In the IMS network, multiple terminals corresponding to an IMPU may be called by using the IMPU. The terminal herein may be an intelligent communications module in the IMS network, and generally is a telephone card, for example, a subscriber identity module, a universal integrated circuit card, or a universal subscriber identity module. An international mobile subscriber identity (IMSI) may uniquely identify a telephone card, but the IMSI cannot be used as a calling number in the IMS network. To call a particular terminal in at least one terminal corresponding to the IMPU, a globally routable user agent uniform resource identifier (GRUU) is introduced in the IMS system. When registered in the IMS network, each terminal is allocated one unique calling number GRUU. Therefore, a terminal identified by a GRUU may be called uniquely by calling the GRUU in the IMS network. The GRUU includes an IMPU and an international mobile equipment identity (IMEI). An IMEI uniquely identifies single card user equipment having only one card slot, that is, single card user equipment into which only one telephone card can be inserted. When user equipment has multiple card slots, an IMEI uniquely identifies one card slot.

In addition to normal services such as phone call, short message service, and fax, the IP-based voice services provided by the IMS system may further include supplementary services such as call transfer, call barring, and call waiting. When a user configures a supplementary service, the user may send a supplementary service configuration request to a server in the IMS network, for example, a telephone application service, to configure a supplementary service corresponding to a GRUU. The telephony application server saves the supplementary service configured by the user in the supplementary service configuration request. For example, the supplementary service configured by the user may be barring a call from GRUU-1, that is, barring a call from a telephone card identified by GRUU-1. When an IMPU does not change, because an IMEI in a GRUU corresponds to a card slot, when a card slot into which a telephone card is inserted changes, a GRUU obtained after registration is performed in the IMS network by using the telephone card also changes, that is, a correspondence between the telephone card and the GRUU changes. In this way, an error may occur in a correspondence between the supplementary service that corresponds to the GRUU and that is saved in the telephony application server and the telephone card, causing an error to the supplementary service of the telephone card.

SUMMARY

Embodiments of the present disclosure provide a service processing method, and user equipment, to resolve a problem in the prior art that because when an IMPU does not change, a card slot into which a telephone card is inserted changes, and a corresponding GRUU changes, a supplementary service that corresponds to the changed GRUU and that is saved in a server does not correspond to the telephone card, a supplementary service error of the telephone card is caused.

In the service processing method, and the user equipment that are provided in the embodiments of the present disclosure, after the user equipment registers with an IMS network and obtains a first GRUU, if the user equipment saves a mapping relationship between a first IMSI and a second GRUU, it indicates that a first telephone card is already registered and the second GRUU is obtained, that is, a GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. In this case, a supplementary service that corresponds to the second GRUU and that is saved in a server in the IMS network is a supplementary service that is previously configured by a user and that is of the first telephone card, but a supplementary service that corresponds to the first GRUU and that is saved in the server is not the supplementary service of the first telephone card. Therefore, if the second GRUU and the first GRUU have a same IMPU, the user equipment may configure the supplementary service corresponding to the first GRUU to a supplementary service the same as the supplementary service corresponding to the second GRUU. Therefore, when an IMPU does not change but an GRUU changes, the first telephone card that is registered and for which the first GRUU is obtained corresponds to the supplementary service that is previously configured by the user and that is of the first telephone card, thereby resolving a problem in the prior art that because when an IMPU does not change, a card slot into which a telephone card is inserted changes, and a corresponding GRUU changes, a supplementary service that corresponds to the changed GRUU and that is saved in a server does not correspond to the telephone card, a supplementary service error of the telephone card is caused.

DESCRIPTION OF EMBODIMENTS

The following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely some but not all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

A voice over Long Term Evolution (LTE) (VoLTE) based on an IMS network is a most ideal solution to a voice service of a 4^thgeneration mobile communications system (4G). For a basic architecture of the IMS network, refer to FIG. 1. In the IMS network architecture, a serving call session control function (S-CSCF) server may be configured to: maintain registration information of a user, and execute a session control service for a terminal (or User Equipment, UE). An application server (AS) may execute a specific service, for example, a telephony application server (TAS) may execute supplementary services such as call hold, call transfer, or call barring for the user. The terminal may communicate with a proxy call session control function (P-CSCF) server by using a Session Initiation Protocol (SIP) message, to perform IMS operations such as registration and session control. The terminal may communicate with the AS by using a Hyper Text Transfer Protocol (HTTP) message, and a Ut interface between the terminal and the AS may be used to configure a service, for example, the UE configures a supplementary service of a telephone card by using the Ut interface. A home subscriber server (HSS) is an important composition part of a control layer on the IMS, and may support a main user database that is used to process invoking/session and that is of an IMS network. In addition, the IMS network architecture may further include some interfaces between the terminal and the server in the IMS network and between servers.

The terminal in this application may be an intelligent communications module in the IMS network, and generally is a telephone card, for example, may be a subscriber identity module (SIM) card, a universal integrated circuit card (UICC card), or a universal subscriber identity module (USIM) card. The user equipment in this application may be user equipment into which a telephone card may be inserted for communication, for example, may be a mobile phone having at least two card slots, a personal communication service (PCS) phone, a Session Initiation Protocol phone, a personal digital assistant (PDA), or another portable, pocket-sized, handheld, and in-vehicle mobile device. Using the mobile phone as an example, a development trend of future mobile phones is: dual card, dual 4G, multi card, and full frequency. Therefore, when a user inserts a telephone card into any card slot, the user may normally use various services of the mobile phone.

When the user equipment registers with the IMS network by using any telephone card, the user equipment obtains a GRUU corresponding to the telephone card. This application is described by using an example in which a server allocating a GRUU to a telephone card in the user equipment and saving and executing a supplementary service is a telephony application server TAS in the IMS network. The GRUU obtained through registration includes an IMPU and an IMEI. The IMPU is a uniform resource identifier (URI), and may be a number, a text, or an identifier including a number. The IMEI includes a 15-digit number, and each digit of the number may be any number from zero to nine.

During registration, the user equipment may add a +sip.instance header to a registration request sent to the TAS, where the +sip.instance header usually includes an IMEI of the terminal. For example, the IMPU may be represented as: sip:userAihome.net, the IMEI may be represented as: 651725741582348 (a 15-digit decimal number), and a GRUU includes the IMPU and the IMEI, and may be: sip:userAihome.net; gr=urn:uuid: 651725741582348. When the user performs supplementary service configuration such call transfer and call barring, the user may configure a supplementary service corresponding to the GRUU. Specifically, the user equipment may send a supplementary service configuration request to the TAS in the IMS network, where the supplementary service configuration request carries the GRUU and a specific supplementary service needing to be configured, for example, barring the GRUU from initiating a call. After receiving the supplementary service configuration request, the TAS saves the supplementary service corresponding to the GRUU, and returns a configuration acknowledgement response to the user equipment to notify the user equipment that supplementary service configuration is completed.

When a same telephone card corresponds to different IMPUs, supplementary services corresponding to the telephone card may be different. For example, if the IMPU is Home, the supplementary service corresponding to the telephone card may be call-in barring, and if the IMPU is Company, the supplementary service corresponding to the telephone card may be call-out barring. Therefore, when the IMPU changes, the supplementary service corresponding to the telephone card may change. Therefore, when the GRUU changes due to a change of the IMPU corresponding to the telephone card, a supplementary service corresponding to the changed GRUU may not correspond to the telephone card. However, when the IMPU does not change, and the GRUU corresponding to the telephone card changes, a supplementary service corresponding to the changed GRUU needs to correspond to the telephone card, to ensure that no error is caused to the supplementary service.

In the embodiments of the present disclosure, a case in which a GRUU corresponding to a telephone card changes when an IMPU does not change is described.

Referring to FIG. 2, an embodiment of the present disclosure provides a service processing method. Main steps may include:

101: User equipment registers with an Internet Protocol IP multimedia subsystem IMS network by using a first international mobile subscriber identity IMSI corresponding to a first telephone card, and obtains a first globally routable user agent uniform resource identifier GRUU.

In this step, when the first telephone card is inserted into the user equipment, the user equipment may read an identity, that is, the first IMSI, of the first telephone card from the first telephone card, reads an IMEI that is saved in the user equipment and that corresponds to a card slot into which the first telephone card is inserted, and obtains an IMPU currently corresponding to the first telephone card. Then, the user equipment may send a registration request to a P-CSCF server, an S-CSCF server, a TAS server, or the like in the IMS network by using the first telephone card, to request to obtain the first GRUU allocated by the TAS in the IMS network. The first GRUU obtained through registration includes the IMPU corresponding to the first telephone card and the IMEI corresponding to the card slot into which the first telephone card is inserted.

102: If the user equipment saves a mapping relationship between the first IMSI and a second GRUU, and the first GRUU and the second GRUU have a same Internet Protocol IP multimedia public identity IMPU, the user equipment configures a first supplementary service to a supplementary service the same as a second supplementary service.

The first supplementary service is a supplementary service corresponding to the first GRUU, and the second supplementary service is a supplementary service corresponding to the second GRUU.

After the user equipment performs registration by using the first telephone card and obtains the first GRUU, if the user equipment saves the mapping relationship between the first IMSI corresponding to the first telephone card and the second GRUU, it indicates that before the first telephone card is currently inserted into the user equipment, the first telephone card is already registered and the second GRUU is obtained, that is, a GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. Therefore, after the first GRUU is obtained through current registration, a supplementary service that corresponds to the second GRUU and that is saved in the TAS in the IMS network is a supplementary service that is configured when the first telephone card is previously inserted into the user equipment, and a supplementary service that corresponds to the first GRUU and that is saved in the TAS is a supplementary service that is previously configured by the user and that is of another telephone card, and is not a supplementary service corresponding to the first telephone card. Therefore, if the first GRUU and the second GRUU have a same IMPU, the user equipment may configure the first supplementary service to the supplementary service the same as the second supplementary service, that is, configure the supplementary service corresponding to the first GRUU to the supplementary service the same as the supplementary service corresponding to the second GRUU. In this way, when an IMPU does not change but a GRUU changes, the first telephone card that is registered and for which the first GRUU is obtained can correspond to the supplementary service that is previously configured by the user, to ensure that no error is caused to the supplementary service of the first telephone card.

Specifically, the configuring, by the user equipment, a first supplementary service to a supplementary service the same as a second supplementary service may include: if the user previously configures the supplementary service corresponding to the second GRUU corresponding to the first telephone card, sending, by the user equipment, a supplementary service configuration request to the TAS, to configure the first supplementary service to the supplementary service the same as the second supplementary service saved in the TAS, so that the first telephone card corresponds to the previously configured supplementary service of the first telephone card, thereby ensuring that no error is caused to the supplementary service of the first telephone card; or if the user previously does not configure the supplementary service corresponding to the second GRUU corresponding to the first telephone card, that is, the supplementary service that corresponds to the second GRUU and that is saved in the TAS is null, the user equipment may instruct the TAS to delete the supplementary service that corresponds to the first GRUU and that is saved in the TAS, thereby ensuring that no error is caused to the supplementary service of the first telephone card.

It should be noted that if the first GRUU and the second GRUU have different IMPUs, telephone cards corresponding to different IMPUs may correspond to different supplementary services. Therefore, the first supplementary service does not need to be configured to the supplementary service the same as the second supplementary service.

In the service processing method provided in this embodiment of the present disclosure, after the user equipment registers with an IMS network and obtains a first GRUU, if the user equipment saves a mapping relationship between a first IMSI and a second GRUU, it indicates that a first telephone card is already registered and the second GRUU is obtained, that is, a GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. In this case, a supplementary service that corresponds to the second GRUU and that is saved in a server in the IMS network is a supplementary service that is previously configured by a user and that is of the first telephone card, but a supplementary service that corresponds to the first GRUU and that is saved in the server is not the supplementary service of the first telephone card. Therefore, if the second GRUU and the first GRUU have a same IMPU, the user equipment may configure the supplementary service corresponding to the first GRUU to a supplementary service the same as the supplementary service corresponding to the second GRUU. Therefore, when an IMPU does not change but an GRUU changes, the first telephone card that is registered and for which the first GRUU is obtained corresponds to the supplementary service that is previously configured by the user and that is of the first telephone card, thereby resolving a problem in the prior art that because when an IMPU does not change, a card slot into which a telephone card is inserted changes, and a corresponding GRUU changes, a supplementary service that corresponds to the changed GRUU and that is saved in a server does not correspond to the telephone card, a supplementary service error of the telephone card is caused.

Another embodiment of the present disclosure describes a service processing method by using an example in which user equipment is a dual card mobile phone, and only one telephone card is inserted into the mobile phone.

For example, if a first telephone card is previously inserted into card slot 2 of the mobile phone, the first telephone card is registered, a second GRUU is obtained, the second GRUU includes an IMPU and an IMEI-2, a second supplementary service S2 is configured, and the first telephone card is currently inserted into card slot 1 of the mobile phone, referring to FIG. 3, main steps of the method may include:

201: The user equipment registers with an Internet Protocol IP multimedia subsystem IMS network by using a first international mobile subscriber identity IMSI corresponding to a first telephone card, and obtains a first globally routable user agent uniform resource identifier GRUU.

If the first telephone card is inserted into card slot 1 (corresponding to an IMEI-1) of the mobile phone, and no telephone card is inserted into card slot 2 (corresponding to an IMEI-2) of the mobile phone, the mobile phone may register with the IMS network by using the first telephone card. For example, a registration process may include:

1. The mobile phone initiates a registration request to the IMS network by using the first telephone card, where the registration request passes through a P-CSCF and arrives at an S-CSCF, and the registration request carries an IMPU and the IMEI-1 that corresponds to card slot 1 into which the first telephone card is currently inserted.

2. The S-CSCF is used to replace the mobile phone and initiates registration to the TAS, where the registration message carries the IMPU corresponding to the first telephone card.

3. The TAS returns an acknowledgement message to the S-CSCF.

4. The S-CSCF returns the acknowledgement message to the mobile phone through the P-CSCF, where the acknowledgement message carries the first GRUU allocated to the mobile phone.

If the first GRUU obtained by the mobile phone after the mobile phone performs registration by using the first telephone card includes the IMPU and the IMEI-1, when the first GRUU is called in the IMS network, the first telephone card may be called uniquely.

After the first telephone card is currently inserted into card slot 1 and the first GRUU is obtained, the mobile phone saves at least a correspondence shown in Table 1-1, and the TAS saves at least a supplementary service shown in Table 2-1.

TABLE 1-1

Mobile phone
First IMSI, second GRUU

TABLE 2-1

TAS
Second supplementary service (S2)

As shown in Table 1, the mobile phone saves a mapping relationship between the first IMSI and the second GRUU.

202: If the user equipment saves a mapping relationship between the first IMSI and a second GRUU, and the second GRUU and the first GRUU have a same Internet Protocol IP multimedia public identity IMPU, the user equipment queries a server for a second supplementary service and saves the second supplementary service.

The second supplementary service is a supplementary service corresponding to the second GRUU. After the first GRUU is obtained in step 201, using Table 1 as an example, if the mobile phone saves the mapping relationship between the first IMSI and the second GRUU, it indicates that before the first telephone card is currently inserted into the mobile phone, the first telephone card is already registered and the second GRUU is obtained, that is, the GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. Therefore, after current registration is performed and the first GRUU is obtained, a supplementary service (that is, the second supplementary service) that corresponds to the second GRUU and that is saved in the TAS in the IMS network is a supplementary service that is configured when the first telephone card is previously inserted into the mobile phone. However, a supplementary service (that is, a first supplementary service) that corresponds to the first GRUU and that is saved in the TAS is a supplementary service that is previously configured by the user and that is of another telephone card, and is not the supplementary service corresponding to the first telephone card. Therefore, when the second GRUU and the first GRUU have the same IMPU, the mobile phone may query the TAS for the second supplementary service, and after receiving a query response sent by the TAS, save the second supplementary service carried in the query response, that is, save the supplementary service that is set by the user before the current registration and that is of the first telephone card, so as to configure the first supplementary service to a supplementary service the same as the saved second supplementary service, so that when the IMPU does not change but the GRUU changes, the first telephone card corresponds to the previously configured supplementary service of the first telephone card, thereby ensuring that no error is caused to the supplementary service of the first telephone card.

After the second supplementary service is saved, the correspondence that is saved in the mobile phone and that is shown in Table 1-1 changes to a correspondence shown in Table 1-2.

TABLE 1-2

Mobile phone
First IMSI, second GRUU

Second supplementary service (S2)

It should be noted that in this step if the mobile phone does not obtain through querying the second supplementary service when querying the TAS for the second supplementary service, that is, the TAS does not save the second supplementary service, it indicates that a supplementary service is not configured for the first telephone card when the first telephone card is previously inserted into the mobile phone. In this case, after the first telephone card is currently inserted into the mobile phone, the first supplementary service is configured to null, to configure the first supplementary service to the supplementary service the same as the second supplementary service, so that no error is caused to the supplementary service of the first telephone card.

Further, after the mobile phone queries the TAS for the second supplementary service and saves the second supplementary service, the method may further include: sending, by the mobile phone, a second deletion instruction to the TAS, to instruct the TAS to delete the second supplementary service currently saved in the TAS.

Because the first GRUU is obtained after the first telephone card is registered, the TAS executes the supplementary service of the first telephone card according to the supplementary service corresponding to the first GRUU. Therefore, after the second supplementary service is saved, the mobile phone may send a second deletion instruction carrying the second GRUU to the TAS, to instruct the TAS to delete the second supplementary service currently saved in the TAS. In this way, when a second telephone card is inserted into card slot 2 of the mobile phone next time and the second GRUU is obtained, an impact of the current second supplementary service (the supplementary service of the first telephone card) on a supplementary service of the second telephone card may be avoided. In addition, after sending the second deletion instruction to the TAS, the mobile phone may further receive a configuration acknowledgement response sent by the TAS, to notify the mobile phone that the TAS already successfully deletes the second supplementary service.

203: The user equipment sends a first deletion instruction to the server, to instruct the server to delete a first supplementary service currently saved in the server.

When configuring the first supplementary service to the supplementary service the same as the second supplementary service, because the TAS does not automatically update the first supplementary service to the supplementary service the same as the second supplementary service, and the TAS can delete an old supplementary service only by receiving a deletion instruction sent by the mobile phone, and add a new supplementary service by receiving a configuration request sent by the mobile phone, in this step, before the first supplementary service is configured, the first supplementary service saved in the TAS needs to be deleted first. If the first supplementary service in the TAS is not deleted before the first supplementary service is configured, after the configuration, in addition to the old first supplementary service before the configuration, the TAS further saves the new first supplementary service the same as the second supplementary service, causing an error to the supplementary service. In addition, after sending the first deletion instruction to the TAS, the mobile phone may further receive a configuration acknowledgement response sent by the TAS, to notify the mobile phone that the TAS already successfully deletes the first supplementary service.

It should be noted that when the TAS receives the first deletion instruction that is sent by the user equipment and that is used to instruct the TAS to delete the first supplementary service, the TAS may not save the first supplementary service. In this case, the TAS does not perform a deletion operation, but still sends a configuration acknowledgment response to the mobile phone.

204: The user equipment configures, by using the server according to the saved second supplementary service, the first supplementary service to a supplementary service the same as the second supplementary service.

In this step, the mobile phone sends a supplementary service configuration request to the TAS according to the saved second supplementary service, to configure the first supplementary service to the supplementary service the same as the second supplementary service, so that after the first telephone card is currently inserted into the mobile phone, the first telephone card corresponds to the supplementary service that is previously configured by the user and that is of the first telephone card, thereby ensuring that no error is caused to the supplementary service.

After the first supplementary service is configured to the supplementary service the same as the second supplementary service, a correspondence saved in the TAS may be shown in Table 2-2.

TABLE 2-2

TAS
First supplementary service (S1)

205: The user equipment deletes the saved second supplementary service.

After the mobile phone configures, according to the saved second supplementary service, the first supplementary service to the supplementary service the same as the second supplementary service, the mobile phone may further delete the saved second supplementary service. After the second supplementary service is deleted, a correspondence saved in the mobile phone may be shown in Table 1-3.

TABLE 1-3

Mobile phone
First IMSI, second GRUU

In addition, the method in this embodiment of the present disclosure may include: updating, by the mobile phone, the mapping relationship between the first IMSI and the second GRUU to a mapping relationship between the first IMSI and the first GRUU.

Specifically, after the first telephone card is registered and the first GRUU is obtained, if the mobile phone saves the mapping relationship between the first IMSI and the second GRUU, the mobile phone may update the mapping relationship between the first IMSI and the second GRUU when the first telephone card is previously inserted into the mobile phone to the mapping relationship between the first IMSI and the first GRUU when the first telephone card is currently inserted into the mobile phone. After the mapping relationship between the first IMSI and the second GRUU is updated to the mapping relationship between the first IMSI and the first GRUU, a correspondence saved in the mobile phone may be shown in Table 1-4.

TABLE 1-4

Mobile phone
First IMSI, first GRUU

It should be noted that this embodiment of the present disclosure is described by using an example in which after the first GRUU is obtained, the mobile phone saves the mapping relationship between the first IMSI and the second GRUU. If the mobile phone does not save a mapping relationship between the first IMSI and any GRUU, and the GRUU includes the first GRUU and the second GRUU, the mobile phone saves the mapping relationship between the first IMSI and the first GRUU.

Specifically, after the first GRUU is obtained in step 201, if the mobile phone does not save the mapping relationship between the first IMSI and any GRUU, it indicates that the first telephone card has not been inserted into the mobile phone. In this case, the mobile phone may save the mapping relationship between the first IMSI and the GRUU for the first time, to update the mapping relationship between the first IMSI and the GRUU later.

In addition, after configuring the first supplementary service to the supplementary service the same as the second supplementary service, the mobile phone may further re-configure a new first supplementary service by using the TAS, to update the supplementary service of the first telephone card. Specifically, the mobile phone may instruct the TAS to delete the first supplementary service currently saved in the TAS, and send a supplementary service configuration request to the TAS by using the first telephone card and a Ut interface between the mobile phone and the TAS in the IMS network. For example, a supplementary service in the supplementary service configuration request may be: barring a call from the first GRUU, that is, barring a call from the first telephone card corresponding to the first GRUU in card slot 1. After receiving the supplementary service configuration request that is sent by the mobile phone by using the Ut interface, the TAS saves the supplementary service that corresponds to the first GRUU and that is in the supplementary service configuration request, and sends a configuration acknowledgement response to the mobile phone. The configuration acknowledgement response is used to notify the mobile phone that the supplementary service is configured completely.

In this embodiment of the present disclosure, after sending the first deletion instruction or the second deletion instruction to the TAS, the mobile phone may further receive the configuration acknowledgement response sent by the TAS. For a flowchart of interaction among the mobile phone, the P-CSCF in the IMS network, the S-CSCF in the IMS network, and the TAS, refer to FIG. 4.

It should be noted that, this embodiment of the present disclosure is described by using an example in which only the first telephone card is inserted into the mobile phone. Certainly, another telephone card may be inserted, and the telephone card is not limited to the first telephone card.

In addition, the user equipment in this embodiment of the present disclosure is described by using an example in which the user equipment is the dual card mobile phone. Certainly, the user equipment in this embodiment of the present disclosure may be a multi-card mobile phone, or another user equipment having at least two card slots. This is not limited in this embodiment of the present disclosure.

In the service processing method provided in this embodiment of the present disclosure, after user equipment registers with an IMS network and obtains a first GRUU, if the user equipment saves a mapping relationship between a first IMSI and a second GRUU, it indicates that a first telephone card is already registered and the second GRUU is obtained, that is, a GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. In this case, a supplementary service that corresponds to the second GRUU and that is saved in a server in the IMS network is a supplementary service that is previously configured by a user and that is of the first telephone card, but a supplementary service that corresponds to the first GRUU and that is saved in the server is not the supplementary service of the first telephone card. Therefore, if the second GRUU and the first GRUU have a same IMPU, the user equipment may configure the supplementary service corresponding to the first GRUU to a supplementary service the same as the supplementary service corresponding to the second GRUU. Therefore, when an IMPU does not change but an GRUU changes, the first telephone card that is registered and for which the first GRUU is obtained corresponds to the supplementary service that is previously configured by the user and that is of the first telephone card, thereby resolving a problem in the prior art that because when an IMPU does not change, a card slot into which a telephone card is inserted changes, and a corresponding GRUU changes, a supplementary service that corresponds to the changed GRUU and that is saved in a server does not correspond to the telephone card, a supplementary service error of the telephone card is caused.

Still another embodiment of the present disclosure describes a service processing method by using an example in which user equipment is a dual card mobile phone and a first telephone card (corresponding to a first IMSI) and a second telephone card (corresponding to a second IMSI) are inserted into the dual card mobile phone.

For example, correspondences shown in Table 3 exist respectively when the first telephone card is previously inserted into the mobile phone and when the first telephone card is currently inserted into the mobile phone, and a second GRUU and a first GRUU have a same IMPU.

Referring to FIG. 5, the method described in this embodiment of the present disclosure may mainly include the following steps.

301: The user equipment registers with an Internet Protocol IP multimedia subsystem IMS network by using a first international mobile subscriber identity IMSI corresponding to a first telephone card, and obtains a first globally routable user agent uniform resource identifier GRUU.

For a specific process of obtaining the first GRUU in step 301, refer to descriptions of step 201. It should be noted that when the first telephone card and the second telephone card are inserted into the mobile phone at the same time, the mobile phone may also register with the IMS network by using the second IMSI and obtain the second GRUU.

After the first GRUU is obtained by using the first IMSI, the correspondence in Table 3 changes to the correspondence in Table 4.

According to the correspondence shown in Table 4, after the first telephone card is registered and the first GRUU is obtained, the mobile phone saves at least correspondences shown in Table 5-1, and a TAS saves at least supplementary services shown in Table 6-1.

TABLE 5-1

Mobile phone
First IMSI, second GRUU

Second IMSI, first GRUU

TABLE 6-1

TAS
First supplementary service (S1)

Second supplementary service (S2)

As can be known from Table 5-1, the mobile phone saves a mapping relationship between the first IMSI and the second GRUU and a mapping relationship between the second IMSI and the first GRUU.

302: If the user equipment saves a mapping relationship between the first IMSI and a second GRUU and further saves a mapping relationship between a second IMSI corresponding to a second telephone card and the first GRUU, and the first GRUU and the second GRUU have a same Internet Protocol IP multimedia public identity IMPU, the user equipment queries a server for a first supplementary service, and saves a first mapping relationship, where the first mapping relationship is a mapping relationship among the second IMSI, the first GRUU, and the first supplementary service.

If the mobile phone saves the mapping relationship between the first IMSI and the second GRUU, it indicates that before the first telephone card is currently inserted into the mobile phone, the first telephone card is already registered and the second GRUU is obtained, that is, the GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. Therefore, after current registration is performed and the first GRUU is obtained, a supplementary service (that is, the second supplementary service) that corresponds to the second GRUU and that is saved in the TAS in the IMS network is a supplementary service that is configured when the first telephone card is previously inserted into the mobile phone. However, the supplementary service that corresponds to the first GRUU and that is saved in the TAS is a supplementary service that is previously configured by the user and that is of another telephone card, and is not the supplementary service corresponding to the first telephone card. Therefore, if the first GRUU and the second GRUU have a same IMPU, the mobile phone may query the TAS for the second supplementary service and save the second supplementary service, to save a supplementary service that is set by the user before current registration and that is of the first telephone card, so as to configure, when the IMPU does not change and according to the saved second supplementary service, the first supplementary service to a supplementary service the same as the second supplementary service.

Similarly, if the mobile phone further saves the mapping relationship between the second IMSI corresponding to the second telephone card and the first GRUU, it indicates that before the second telephone card is currently inserted into the mobile phone, the second telephone card is registered and the first GRUU is obtained, that is, the GRUU corresponding to the second telephone card changes from the first GRUU to the second GRUU. Therefore, if the first GRUU and the second GRUU have a same IMPU, the second supplementary service needs to be configured to the supplementary service that is previously configured by the user and that is of the second telephone card, that is, the supplementary service the same as the first supplementary service, so that when the IMPU does not change, the second telephone card corresponds to the supplementary service of the second telephone card, thereby ensuring that no error is caused to the supplementary service of the second telephone card.

Therefore, the mobile phone may query the TAS for the first supplementary service, and saves a mapping relationship among the second IMSI, the first GRUU, and the first supplementary service, to save the supplementary service previously configured for the first telephone card, that is, the first supplementary service, into the mobile phone, so that the second supplementary service may be configured, later according to the first supplementary service saved in the mobile phone, to the supplementary service the same as the first supplementary service.

In this case, the correspondence that is saved in the mobile phone and that is shown in Table 5-1 changes to the correspondence shown in Table 5-2.

TABLE 5-2

Mobile phone
First IMSI, second GRUU

Second IMSI, first GRUU, and first supplementary

303: The user equipment queries the server for a second supplementary service, and saves the second supplementary service.

After saving the first mapping relationship, the mobile phone may query the TAS for the second supplementary service and save the second supplementary service, so as to configure, according to the second supplementary service saved in the mobile phone, the first supplementary service to a supplementary service the same as the second supplementary service.

In this case, the correspondence shown in the mobile phone may be shown in Table 5-3.

TABLE 5-3

Mobile phone

304: The user equipment sends a first deletion instruction to the server, to instruct the server to delete the first supplementary service currently saved in the server.

After the mobile phone sends the deletion instruction to the TAS to instruct the TAS to delete the first supplementary service, the supplementary service saved in the TAS may be shown in Table 6-2.

TABLE 6-2

TAS
Second supplementary service (S2)

305: The user equipment configures, by using the server according to the saved second supplementary service, the first supplementary service to a supplementary service the same as the second supplementary service.

After the mobile phone sends a supplementary service configuration request to the TAS to configure the first supplementary service to the supplementary service the same as the second supplementary service, the supplementary service saved in the TAS may be shown in Table 6-3.

TABLE 6-3

TAS

Second supplementary service (S2)

306: The user equipment deletes the saved second supplementary service.

After the mobile phone deletes the second supplementary service, the correspondence saved in the mobile phone may be shown in Table 5-4.

Second IMSI, first GRUU, and first supplementary

service (first mapping relationship)

For specific descriptions of step 303 to step 306, refer to step 202 to step 205, and details are not described herein again.

307: If the user equipment registers with the IMS network by using the second IMSI and obtains the second GRUU, the user equipment sends a second deletion instruction to the server, to instruct the server to delete the second supplementary service currently saved in the server, and configures, by using the server, the second supplementary service to a supplementary service the same as the first supplementary service in the first mapping relationship.

Because the first telephone card and the second telephone card are currently inserted into the mobile phone at the same time, the mobile phone may perform registration by using the second IMSI and obtain the second GRUU. In this case, the mobile phone may send the second deletion instruction to the TAS, to instruct the TAS to delete the second supplementary service. After instructing the TAS to delete the second supplementary service, the mobile phone may send a supplementary service configuration request to the TAS, to configure the second supplementary service to the new supplementary service the same as the first supplementary service in the first mapping relationship saved in step 302, so that the second telephone card corresponds to the previously configured supplementary service of the second telephone card, thereby ensuring that no error is caused to the supplementary service of the second telephone card.

After the second supplementary service currently saved in the TAS is deleted, the supplementary service saved in the TAS may be shown in Table 6-4.

TABLE 6-4

TAS
First supplementary service (S2)

After the second supplementary service is configured, by using the TAS, to the supplementary service the same as the first supplementary service in the first mapping relationship, the supplementary service saved in the TAS may be shown in Table 6-5.

308: After configuring the second supplementary service to the supplementary service the same as the first supplementary service in the first mapping relationship, the user equipment deletes the first supplementary service in the first mapping relationship, and updates the mapping relationship between the second IMSI and the first GRUU to a mapping relationship between the second IMSI and the second GRUU.

After the first supplementary service in the first mapping relationship is deleted, the correspondence saved in the mobile phone may be shown in Table 5-5.

TABLE 5-5

After the mapping relationship between the second IMSI and the first GRUU is updated to the mapping relationship between the second IMSI and the second GRUU in this step, the correspondence saved in the mobile phone may be shown in Table 5-6.

After the mapping relationship is updated, the correspondence saved in the mobile phone may be shown in Table 5-7.

TABLE 5-7

Mobile phone

Second IMSI, second GRUU

It should be noted that this embodiment of the present disclosure is described by using an example in which the first telephone card is previously inserted into the mobile phone. If the first telephone card is not inserted into the mobile phone previously, that is, after the first GRUU is obtained, if the mobile phone does not save a mapping relationship between the first IMSI and any GRUU, and the GRUU includes the first GRUU and the second GRUU, the mobile phone may save the mapping relationship between the first IMSI and the first GRUU, to save the mapping relationship between the first IMSI and the GRUU for the first time, so as to update the mapping relationship between the first IMSI and the GRUU later.

Similarly, if the second telephone card is registered and the second GRUU is obtained, if the mobile phone does not save a mapping relationship between the second IMSI and any GRUU, and the GRUU includes the first GRUU and the second GRUU, that is, the second telephone card is not inserted into the mobile phone previously, the mobile phone may save the mapping relationship between the second IMSI and the second GRUU, to save the mapping relationship between the second IMSI and the GRUU for the first time, so as to update the mapping relationship between the second IMSI and the GRUU later.

In addition, this embodiment of the present disclosure is described by using an example in which the first telephone card and the second telephone card are inserted into the mobile phone. Other telephone cards such as the first telephone card and a third telephone card may be inserted into the mobile phone. This is not limited in this embodiment of the present disclosure.

Another embodiment of the present disclosure describes a service processing method by using an example in which user equipment is a dual card mobile phone, and only a first telephone card is inserted into the mobile phone.

For example, if the first telephone card is previously inserted into card slot 2 of the mobile phone, the first telephone card is registered, the second GRUU is obtained, the second GRUU includes an IMPU and an IMEI-2, a second supplementary service S2 is configured, and the first telephone card is currently inserted into card slot 1 (corresponding to an IMEI-1) of the mobile phone, referring to FIG. 6, main steps of the method may include:

401: The user equipment registers with an Internet Protocol IP multimedia subsystem IMS network by using a first international mobile subscriber identity IMSI corresponding to a first telephone card, and obtains a first globally routable user agent uniform resource identifier GRUU.

For a specific process in which the mobile phone performs registration by using the first telephone card and obtains the first GRUU, refer to descriptions of step 201. For example, the first GRUU obtained through registration includes an IMPU and the IMEI-1.

After the first GRUU is obtained by using the first IMSI, the mobile phone saves at least the correspondence shown in Table 7-1.

TABLE 7-1

Mobile phone
First IMSI, second GRUU, and supplementary service

(S2) corresponding to the second GRUU

TABLE 8-1

TAS
Second supplementary service (S2)

402: If the user equipment saves a mapping relationship between the first IMSI and a second GRUU, and the second GRUU and the first GRUU have a same Internet Protocol IP multimedia public identity IMPU, if the user equipment saves a second mapping relationship, and the second mapping relationship is a mapping relationship among the first IMSI, the second GRUU, and a second supplementary service, the user equipment sends a first deletion instruction to a server, to instruct the server to delete a first supplementary service currently saved in the server.

The first supplementary service is a supplementary service corresponding to the first GRUU, and the second supplementary service is a supplementary service corresponding to the second GRUU.

If the mobile phone saves the mapping relationship between the first IMSI and the second GRUU, it indicates that before the first telephone card is currently inserted into the user equipment, the first telephone card is already registered and the second GRUU is obtained, that is, the GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. Therefore, after current registration is performed and the first GRUU is obtained, a supplementary service (that is, the second supplementary service) that corresponds to the second GRUU and that is saved in the TAS in the IMS network is a supplementary service that is configured when the first telephone card is previously inserted into the mobile phone. However, a supplementary service (that is, the first supplementary service) that corresponds to the first GRUU and that is saved in the TAS is a supplementary service that is previously configured by the user and that is of another telephone card, and is not the supplementary service corresponding to the first telephone card. In this case, if the second GRUU and the first GRUU have a same IMPU, and the mobile phone saves the mapping relationship among the first IMSI, the second GRUU, and the second supplementary service, that is, the second mapping relationship, the mobile phone may configure, according to the second supplementary service in the second mapping relationship, the first supplementary service to a supplementary service the same as the second supplementary service, so that when the IMPU does not change but the GRUU changes, the first telephone card corresponds to the previously configured supplementary service of the first telephone card, thereby ensuring that no error is caused to the supplementary service of the first telephone card.

When configuring the first supplementary service to the supplementary service the same as the second supplementary service, because the TAS does not automatically update the first supplementary service to the supplementary service the same as the second supplementary service, and the TAS can delete an old supplementary service only by receiving a deletion instruction sent by the mobile phone, and add a new supplementary service by receiving a supplementary service configuration request sent by the mobile phone, in this step, before the first supplementary service is configured, the first supplementary service saved in the TAS needs to be deleted first. If the first supplementary service in the TAS is not deleted before the first supplementary service is configured, after the configuration, in addition to the old first supplementary service before the configuration, the TAS further saves the new first supplementary service the same as the second supplementary service, causing an error to the supplementary service. In addition, after sending the first deletion instruction or a second deletion instruction to the TAS, the mobile phone may further receive a configuration acknowledgement response sent by the TAS.

It should be noted that after receiving the first deletion instruction, because the TAS currently may save the first supplementary service or may not save the first supplementary service, when the TAS currently saves the first supplementary service, the TAS deletes the first supplementary service currently saved in the TAS, and when the server currently does not save the first supplementary service, the TAS does not perform a deletion operation in this step.

403: The user equipment configures, by using the server, the first supplementary service to a supplementary service the same as the second supplementary service in the second mapping relationship.

In this step, the mobile phone sends the supplementary service configuration request to the TAS according to the saved second mapping relationship, to configure the first supplementary service to the supplementary service the same as the second supplementary service in the second mapping relationship, so that after the first telephone card is currently inserted into the mobile phone, the first telephone card corresponds to the previously configured supplementary service of the first telephone card, thereby ensuring that no error is caused to the supplementary service.

In this case, the supplementary service saved in the TAS may be shown in Table 8-2.

TABLE 8-2

TAS
First supplementary service (S2)

404: The user equipment updates the second mapping relationship to a third mapping relationship, where the third mapping relationship is a mapping relationship among the first IMSI, the first GRUU, and the first supplementary service.

After configuring the first supplementary service to the supplementary service the same as the second supplementary service in the second mapping relationship, the mobile phone may update the second mapping relationship to the third mapping relationship, so that after the mobile phone performs registration by using the first IMSI and obtains the second GRUU, the mobile phone may configure, according to the first supplementary service in the third mapping relationship, the second supplementary service to a supplementary service the same as the first supplementary service.

After the mapping relationship is updated, the correspondence saved in the mobile phone may be shown in Table 7-2.

(S2)

405: The user equipment sends a second deletion instruction to the server, to instruct the server to delete the second supplementary service currently saved in the server.

Because the first GRUU is obtained after the first telephone card is registered, the TAS executes the supplementary service of the first telephone card according to the supplementary service corresponding to the first GRUU. Therefore, the mobile phone may send the second deletion instruction carrying the second GRUU to the TAS, to instruct the TAS to delete the second supplementary service currently saved in the TAS, and configure, according to the second mapping relationship saved in the mobile phone, the first supplementary service to the supplementary service the same as the second supplementary service. After the TAS deletes the currently saved second supplementary service, when the second telephone card is inserted into card slot 2 of the mobile phone and is registered next time and the second GRUU is obtained, an impact of the second supplementary service (the supplementary service of the first telephone card) currently saved in the TAS on the supplementary service of the second telephone card may be avoided. In addition, after sending the first deletion instruction or the second deletion instruction to the TAS, the mobile phone may further receive the configuration acknowledgement response sent by the TAS.

In step 401 to step 405 in this embodiment of the present disclosure, for a flowchart of interaction among the mobile phone, a P-CSCF in the IMS network, an S-CSCF in the IMS network, and the TAS in the IMS network, refer to FIG. 7.

In addition, when the first telephone card is inserted into card slot 1, if the second telephone card (corresponding to the second IMSI) is further inserted into card slot 2, referring to FIG. 8, after step 401 to step 404, the method in this embodiment of the present disclosure may further include the following steps.

406: If the user equipment further saves a first mapping relationship, and the first mapping relationship is a mapping relationship among a second IMSI, the first GRUU, and the first supplementary service, when the user equipment performs registration by using the second IMSI and obtains the second GRUU, send a second deletion instruction to the server, to instruct the server to delete the second supplementary service currently saved in the server.

If the mobile phone further saves the mapping relationship among the second IMSI, the first GRUU, and the first supplementary service, it indicates that before the second telephone card is currently inserted into the mobile phone, the second telephone card is already registered, the first GRUU is obtained, and the first supplementary service is configured, that is, the GRUU corresponding to the second telephone card changes from the first GRUU to the second GRUU. Therefore, if the first GRUU and the second GRUU have a same IMPU, the second supplementary service needs to be configured to a supplementary service that is previously configured by the user and that is of the supplementary service, that is, the supplementary service the same as the first supplementary service, so that when the IMPU does not change, the second telephone card corresponds to the supplementary service of the second telephone card, thereby ensuring that no error is caused to the supplementary service of the second telephone card.

Because the TAS does not automatically update the second supplementary service to the supplementary service the same as the first supplementary service, and the TAS can delete an old supplementary service only by receiving a deletion instruction sent by the mobile phone, and add a new supplementary service by receiving a supplementary service configuration request sent by the mobile phone, in this step, before the second supplementary service is configured, the second supplementary service saved in the TAS needs to be deleted first. If the second supplementary service in the TAS is not deleted before the second supplementary service is configured, after the configuration, in addition to the old second supplementary service before the configuration, the TAS further saves the new second supplementary service the same as the first supplementary service, causing an error to the supplementary service.

407: The user equipment configures, by using the server, the second supplementary service to a supplementary service the same as the first supplementary service in the first mapping relationship.

After the TAS deletes the currently saved second supplementary service, the mobile phone may send a supplementary service configuration request to the server according to the second mapping relationship, to configure the second supplementary service to the supplementary service the same as the first supplementary service in the first mapping relationship, so that the second telephone card corresponds to the supplementary service that is previously configured by the user and that is of the second telephone card, thereby ensuring that no error is caused to the supplementary service of the second telephone card.

408: The user equipment updates the first mapping relationship to a fourth mapping relationship, where the fourth mapping relationship is a mapping relationship among the second IMSI, the second GRUU, and the second supplementary service.

After configuring the second supplementary service to the supplementary service the same as the first supplementary service, the mobile phone may further update the first mapping relationship to the fourth relationship, so that after the second telephone card is registered next time and the first GRUU is obtained, the mobile phone may configure, according to the fourth mapping relationship, the first supplementary service to the supplementary service the same as the second supplementary service in the fourth mapping relationship, thereby ensuring that no error is caused to the supplementary service of the second telephone card.

It should be noted that this embodiment of the present disclosure is described by using an example in which after the first GRUU is obtained in step 401, the mobile phone saves the mapping relationship between the first IMSI and the second GRUU, after the first GRUU is obtained in step 401, if the mobile phone does not save a mapping relationship between the first IMSI and any GRUU, and the GRUU includes the first GRUU and the second GRUU, the mobile phone may save a third mapping relationship when configuring the first supplementary service corresponding to the first IMSI, where the third mapping relationship is a mapping relationship among the first IMSI, the first GRUU, and the first supplementary service.

Specifically, after obtaining the first GRUU in step 401, if the mobile phone does not save the mapping relationship between the first IMSI and any GRUU, and the GRUU includes the first GRUU and the second GRUU, it indicates that the first telephone card is not inserted into the mobile phone previously. In this case, when configuring the first supplementary service corresponding to the first IMSI, the mobile phone may save the mapping relationship among the first IMSI, the first GRUU, and the first supplementary service for the first time, so as to update a mapping relationship among the first IMSI, the GRUU, and the supplementary service later.

Similarly, after the second telephone card is registered and the second GRUU is obtained, if the mobile phone does not save a mapping relationship between the second IMSI and any GRUU, and the GRUU includes the first GRUU and the second GRUU, that is, the second telephone card is not inserted into the mobile phone previously, when configuring the second supplementary service corresponding to the second IMSI, the mobile phone may save the mapping relationship between the second IMSI, the second GRUU, and the second supplementary service for the first time, so as to update a mapping relationship among the second IMSI, the GRUU, and the supplementary service.

In the user equipment 500 provided in this embodiment of the present disclosure, after the user equipment registers with an IMS network and obtains a first GRUU, if the user equipment 500 saves a mapping relationship between a first IMSI and a second GRUU, it indicates that a first telephone card is already registered and the second GRUU is obtained, that is, a GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. In this case, a supplementary service that corresponds to the second GRUU and that is saved in a server in the IMS network is a supplementary service that is previously configured by a user and that is of the first telephone card, but a supplementary service that corresponds to the first GRUU and that is saved in the server is not the supplementary service of the first telephone card. Therefore, if the second GRUU and the first GRUU have a same IMPU, the user equipment 500 may configure the supplementary service corresponding to the first GRUU to a supplementary service the same as the supplementary service corresponding to the second GRUU. Therefore, when an IMPU does not change but an GRUU changes, the first telephone card that is registered and for which the first GRUU is obtained corresponds to the supplementary service that is previously configured by the user and that is of the first telephone card, thereby resolving a problem in the prior art that because when an IMPU does not change, a card slot into which a telephone card is inserted changes, and a corresponding GRUU changes, a supplementary service that corresponds to the changed GRUU and that is saved in a server does not correspond to the telephone card, a supplementary service error of the telephone card is caused.

configure, by using the server, the first supplementary service to the supplementary service the same as the second supplementary service in the second mapping relationship.

Optionally, the processor 602 may be further configured to:

Optionally, referring to FIG. 24, the user equipment 600 shown in FIG. 23 may further include:

a transmitter 605, configured to: if the user equipment 600 further saves a first mapping relationship, and the first mapping relationship is a mapping relationship among a second IMSI, the first GRUU, and the first supplementary service, when the user equipment 600 performs registration by using the second IMSI and obtains the second GRUU, send a second deletion instruction to the server, to instruct the server to delete the second supplementary service currently saved in the server, where

Optionally, referring to FIG. 24, the user equipment 600 shown in FIG. 23 may further include:

a transmitter 605, configured to send a second deletion instruction to the server, to instruct the server to delete the second supplementary service currently saved in the server.

Optionally, in the user equipment 600 shown in FIG. 23, the processor 602 may be further configured to:

In the user equipment 600 provided in this embodiment of the present disclosure, after the user equipment registers with an IMS network and obtains a first GRUU, if the user equipment 600 saves a mapping relationship between a first IMSI and a second GRUU, it indicates that a first telephone card is already registered and the second GRUU is obtained, that is, a GRUU corresponding to the first telephone card changes from the second GRUU to the first GRUU. In this case, a supplementary service that corresponds to the second GRUU and that is saved in a server in the IMS network is a supplementary service that is previously configured by a user and that is of the first telephone card, but a supplementary service that corresponds to the first GRUU and that is saved in the server is not the supplementary service of the first telephone card. Therefore, if the second GRUU and the first GRUU have a same IMPU, the user equipment 600 may configure the supplementary service corresponding to the first GRUU to a supplementary service the same as the supplementary service corresponding to the second GRUU. Therefore, when an IMPU does not change but an GRUU changes, the first telephone card that is registered and for which the first GRUU is obtained corresponds to the supplementary service that is previously configured by the user and that is of the first telephone card, thereby resolving a problem in the prior art that because when an IMPU does not change, a card slot into which a telephone card is inserted changes, and a corresponding GRUU changes, a supplementary service that corresponds to the changed GRUU and that is saved in a server does not correspond to the telephone card, a supplementary service error of the telephone card is caused.
