The present disclosure relates to the field of communications technologies, and in particular, to a policy and charging enforcement function (PCEF) apparatus, an online charging apparatus, and an online charging method.
A large-scale deployment of the third Generation (3G) Mobile Communication greatly promotes use of data services. Accurate charging of a data service is a basis of data service development. Policy and charging control (PCC) is a PCC mechanism that is defined by the 3G Partnership Project (3GPP). A core of the PCC mechanism includes when a data flow bearer is established, a gateway device requests, from a Policy and Charging Rules Function (PCRF), a PCC rule of a service data flow. If an application function (AF) provides service layer information of a service to the PCRF, the PCRF generates the PCC rule according to subscriber information stored in a subscription profile repository (SPR), bearer layer information provided by a gateway, and some local policies and service layer information that are configured by an operator in the PCRF, and delivers a command to a PCEF in the gateway to install the PCC rule that is generated. The PCEF performs resource allocation, data flow control, and charging control according to the PCC rule. The PCC mechanism may perform precise control on the service data flow according to an operator policy to implement refined bandwidth operation.
In the foregoing PCC mechanism, the AF is a service network element, and provides related information of a service accessed by a user. For example, the AF can provide information such as a service identity, a service priority indicator, and a service urgency indicator to the PCRF.
In the PCC mechanism, the PCRF is a policy decision entity, and is responsible for controlling quality of service (QoS), a bandwidth, gating, and a charging control policy when user equipment in a home network uses a service, and generating a dynamic policy or specifying a static policy, where the dynamic policy or the static policy is executed by the PCEF.
The PCEF is a policy execution entity, used to execute the dynamic control policy delivered by the PCRF or the static control policy specified by the PCRF. The PCEF may be located in a gateway device, for example, a Gateway General Packet Radio Service (GPRS) Support Node (GGSN), a Packet Data Network (PDN) Gateway (P-GW), or a Wireless Application Protocol (WAP) gateway.
The SPR is a subscription data storage entity, and stores subscription data of a user and maps the subscription data onto an existing system, which may be an online charging system (OCS).
U.S. Patent Application Publication US2015/0156334 A1 discloses a charging control method, a charging trigger apparatus, and an online charging system. The method includes generating, by a charging triggering function (CTF), a resource quota request according to a trigger condition, and sending the resource quota request to an online charging system (OCS), so that the OCS determines a quota type and number after receiving the resource quota request, and allocates a quota for the resource quota request according to the quota type and number determined by the OCS, where the quota and number are determined by the OCS according to the resource quota request.
However, in other approaches, charging of a sponsor is limited only to an offline charging mode. Consequently, a particular service data flow sponsored by the sponsor cannot be online processed, and traffic/duration sponsored by the sponsor cannot be used by an online credit control user in an online credit control process. Therefore, credit control on the user cannot be implemented when the user and the sponsor share costs.

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. 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 user may access the service provider 5 (for example, a video website that provides five-minute free videos) using the user equipment 1. After the user clicks a video, the PCC function apparatus 4 learns a service data flow of the five-minute free video sponsored by the service provider 5, generates a PCC rule of the service data flow, and sends the PCC rule to the PCEF apparatus 2. When the service data flow (that is, the service data flow of the video) of the user equipment 1 uses online charging, the PCEF apparatus 2 determines, according to a rating group that is of the service data flow and that is included in the PCC rule, whether the PCEF apparatus 2 has a credit quota available to the service data flow.
If the PCEF apparatus 2 does not have the credit quota available to the service data flow, the PCEF apparatus 2 sends a credit control request including the rating group to the online charging apparatus 3. After receiving the credit control request, the online charging apparatus 3 determines, based on the credit control request, that the service data flow of the user equipment 1 is data access sponsored by the sponsor, and allocates the available credit quota to the service data flow according to a service unit type sponsored by the sponsor when the service data flow is data access sponsored by the sponsor in order to implement sponsoring of the sponsor. When a reporting condition is satisfied, the PCEF apparatus 2 sends a reporting message to the online charging apparatus 3 such that the online charging apparatus 3 may perform online credit control on the user equipment 1 according to the reporting message, and simultaneously generate a call detail record that can be used for settlement of the sponsor to implement that the user equipment 1 may enjoy a five-minute free video provided by the sponsor.

In step 605, the user equipment 1 accesses a service provider 5 (for example, a video website that provides five-minute free videos), and clicks a piece of content (for example, a video) of the service provider 5. In step 606, the service provider 5 may sponsor a service data flow of the clicked content. In step 607, the PCC function apparatus 4 generates a PCC rule based on sponsoring of the service provider 5.
Further, the PCC rule generated by the PCC function apparatus 4 may be a new PCC rule (there is no existing corresponding PCC rule), or may be an update on an existing PCC rule (there is a corresponding PCC rule). The PCC rule may include a reporting level, which may be a sponsor level, and a rating group corresponding to the service data flow sponsored by a sponsor. Optionally, the PCC rule may further include a sponsor identity, an application service provider identity, and a quota type sponsored by the sponsor. The quota type may be traffic, duration, traffic and duration, or the like.
In step 608, the PCC function apparatus 4 sends the PCC rule to the PCEF apparatus 2, and the PCEF apparatus 2 receives the PCC rule. In step 609, the PCEF apparatus 2 determines, based on a charging manner included in the PCC rule, whether a service data flow of the user equipment 1 uses online charging or offline charging. Because this embodiment is implemented in an online charging state, only an online charging part is described below.
It should be noted that if the PCC rule does not carry any charging manner, the PCEF apparatus 2 determines, according to a charging manner (pre-defined PCC rule) that is statically configured, whether the service data flow of the user equipment 1 uses online charging or offline charging. According to another aspect, if the PCC rule is obtained by modifying an existing PCC rule, the PCEF apparatus 2 may determine, according to a charging manner of the existing PCC rule, whether the service data flow of the user equipment 1 uses online charging or offline charging.
If the service data flow of the user equipment 1 uses online charging, in step 610, the PCEF apparatus 2 determines, based on the PCC rule, that the service data flow of the user equipment 1 is a sponsor service data flow sponsored by the sponsor. For example, the PCEF apparatus 2 may determine, according to the rating group included in the PCC rule, that the service data flow of the user equipment 1 is sponsored by the sponsor and is a sponsor service data flow, or if the PCC rule includes the sponsor identity, the PCEF apparatus 2 may learn, according to the sponsor identity, that the service data flow of the user equipment 1 is sponsored by the sponsor and is a sponsor service data flow. For the sake of simplicity, the service data flow described below is the sponsor service data flow. It should be noted herein that the sponsor service data flow refers to that the sponsor provides cost support for the service data flow. The service data flow may not be provided by the sponsor.
Because the PCC rule may include the reporting level, which is the sponsor level, the PCEF apparatus 2 determines, based on the rating group that is of the service data flow and that is included in the PCC rule, whether the PCEF apparatus 2 has a credit quota available to the service data flow. The available credit quota herein refers to that the credit quota matches the rating group and the quota type of the sponsor service data flow. The sponsor service data flow may directly use the credit quota. It should be noted that if the PCC rule includes only the rating group of the service data flow, the PCEF apparatus 2 may determine, according to the rating group of the service data flow, whether the PCEF apparatus 2 has the credit quota available to the service data flow.
According to another aspect, if the PCEF apparatus 2 does not have the credit quota available to the service data flow, in step 611, the PCEF apparatus 2 sends a credit control request including the rating group to the online charging apparatus 3 such that after the online charging apparatus 3 receives the credit control request, the online charging apparatus 3 may allocate, based on the rating group, the available credit quota to the PCEF apparatus 2. In another possible implementation manner, if the PCC rule includes the quota type, the PCEF apparatus 2 sends a credit control request including the quota type and the rating group to the online charging apparatus 3 such that after the online charging apparatus 3 receives the credit control request, the online charging apparatus 3 may allocate, based on the quota type and the rating group, the available credit quota to the PCEF apparatus 2. It should be noted that if the PCC rule includes the sponsor identity and a service identity, the credit control request may further include the service identity and the sponsor identity of the service data flow, and a function thereof is described below.
In another possible implementation manner, the PCC rule includes the quota type. When the PCEF apparatus 2 does not have the credit quota available to the sponsor service data flow, the PCEF apparatus 2 further sends, to the online charging apparatus 3, a credit control request that includes the quota type and that specifies the sponsor such that the online charging apparatus 3 determines an allocation manner of the credit quota based on the specified sponsor, and allocates a line of credit corresponding to the quota type to the PCEF apparatus 2. Determining an allocation manner of the credit quota based on the specified sponsor may be not reserving a credit quota for an account of the user equipment 1, but merely allocating a virtual quota, where no actual credit control is performed for the quota. Alternatively, according to the specified sponsor and the rating group, whether account reservation for the user equipment 1 needs to be performed is determined. If yes, reservation is performed according to the account of the user equipment 1, to allocate a corresponding quota. In this case, the user equipment 1 and the sponsor jointly pay for access to the service data flow. The allocated quota further includes a quota needed for charging of the user equipment 1. A type of the allocated quota occupies one account reservation limit.
After the online charging apparatus 3 receives the credit control request, the online charging apparatus 3 is configured to determine, based on the credit control request, whether the service data flow of the user equipment 1 is data access sponsored by the sponsor, and allocate the available credit quota to the service data flow. The online charging apparatus 3 sends the available credit quota to the PCEF apparatus 2.
The online charging apparatus 3 determines, according to the received credit control request, whether the service data flow is data access sponsored by the sponsor. The online charging apparatus 3 may determine, according to the sponsor identity included in the credit control request, that the service data flow is data access sponsored by the sponsor. For example, if data access sponsored by the sponsor is a video, the service data flow may be sponsored by the sponsor only when the service data flow is a video.
In step 612, the online charging apparatus 3 determines that a sponsor is charged for the service data flow. In another possible implementation manner, if the credit control request includes the service identity of the service data flow, the online charging apparatus 3 determines whether the service identity specifies the sponsor. If the service identity specifies the sponsor, the online charging apparatus 3 determines that the service data flow is data access sponsored by the sponsor.
In still another possible implementation manner, if the credit control request includes the rating group of the service data flow, the online charging apparatus 3 determines whether the rating group specifies the sponsor. If the rating group specifies the sponsor, the online charging apparatus 3 determines that the service data flow is data access sponsored by the sponsor.
If the service data flow is data access sponsored by the sponsor, in step 613, the online charging apparatus 3 allocates the available credit quota to the service data flow according to the quota type included in the credit control request. The quota type corresponds to a service unit type sponsored by the sponsor. For example, if the service unit type is duration, the quota type is also duration. If the service unit type is traffic, the quota type is also traffic.
Moreover, the online charging apparatus 3 cannot adjust or change the quota type.
If the quota type is traffic and duration, and the user equipment 1 is charged, when allocating the available credit quota, online charging apparatus 3 allocates duration and traffic of same costs, and locks balance of a same account. For example, five RMB is locked in the balance of the account is locked, and duration that corresponds to five renminbi (RMB) and traffic that corresponds to five RMB are simultaneously allocated.
In another possible implementation manner, if the credit control request does not include the quota type, the online charging apparatus 3 may allocate the available credit quota to the service data flow according to a default quota type stored in the online charging apparatus 3. For example, the default quota type is a “duration and traffic” quota type. The default quota type herein is mainly used to determine a quota type corresponding to a service unit type of a sponsor whose service unit type is not specified.
In still another possible implementation manner, if the credit control request does not include the quota type, the online charging apparatus 3 allocates, according to the service unit type that is stored in the online charging apparatus 3 and that corresponds to the sponsor, the available credit quota corresponding to the service unit type to the service data flow. A premise is that the service unit type sponsored by the sponsor is preconfigured in a charging system.
In another possible implementation manner, if the online charging apparatus 3 determines, according to the rating group, that the user equipment 1 needs to be charged, the quota type is a combination of the service unit type of the sponsor and a charging unit type of the user equipment 1, and an available credit quota corresponding to the quota type of the combination is allocated to the service data flow. For example, if the service unit type of the sponsor is traffic, and the charging unit type of the user equipment 1 is duration, the quota type is a combination of traffic and duration.
After the available credit quota is allocated, in step 614, the online charging apparatus 3 sends the available credit quota to the PCEF apparatus 2. After the PCEF apparatus 2 receives the available credit quota, in step 615, the PCEF apparatus 2 records use information of the credit quota. It should be noted that the recorded use information corresponds to one of the sponsor identity, the rating group, the application service provider identity, or a combination thereof.
According to another aspect, if the available credit quota includes duration, the PCEF apparatus 2 records a start time, an end time, and an effective use duration of using the credit quota by the service data flow in a current reporting period. The use information includes the start time, the end time, and the effective use duration of using the credit quota by the service data flow in the current reporting period. For example, the current reporting period is from a time at which the PCEF apparatus 2 receives the available credit quota to a time at which the PCEF apparatus 2 sends a reporting message. Assuming that the time at which the PCEF apparatus 2 receives the available credit quota is 4:10 p.m., and the time at which the PCEF apparatus 2 sends the reporting message is 4:30 p.m., the reporting period is from 4:10 p.m. to 4:30 p.m., which is totally 20 minutes. In the 20-minute interval, if there is a service data flow that starts using the credit quota at 4:12 p.m. and that ends using the credit quota at 4:22 p.m., the start time and the end time at which the service data flow uses the credit quota are respectively 4:12 p.m. and 4:22 p.m. In addition, the service data flow may be an intermittent data flow. For example, from 4:12 p.m. to 4:14 p.m. and from 4:17 p.m. to 4:22 p.m., the effective use duration for which the service data flow uses the credit quota is 2 minutes plus 5 minutes, which is totally 7 minutes.
In step 616, the PCEF apparatus 2 determines whether a reporting condition is satisfied. If the reporting condition is satisfied, in step 618, the PCEF apparatus 2 sends the reporting message to the online charging apparatus 3 such that the online charging apparatus 3 performs charging process based on the reporting message, where the reporting message may include the rating group, the sponsor identity, the application service provider identity, and the use information. The use information herein is use information corresponding to the sponsor identity and the application service provider identity.
Further, the reporting condition may be a local reporting condition (that is, a reporting condition stored in the PCEF apparatus 2), or the reporting condition may be sent to the PCEF apparatus 2 in step 615 together with the available credit quota, or as shown in step 617, the reporting condition may be sent by the online charging apparatus 3 to the PCEF apparatus 2. Specific content of the reporting condition may be whether the credit quota runs out, whether a time limit of the credit quota expires, and whether QoS of the service data flow is changed, and the like.
For example, the PCEF apparatus 2 may receive the reporting condition from the online charging apparatus 3. The reporting condition sent by the online charging apparatus 3 to the PCEF apparatus 2 is classified into two types: (1) The reporting condition corresponds to the sponsor, and (2) the reporting condition corresponds to the user equipment 1. For example, the reporting condition of the sponsor may be that the QoS is changed. The reporting condition of the user equipment 1 may be that a user location is changed. The PCEF apparatus 2 needs to send the reporting message to the online charging apparatus 3 when either of the reporting condition of the sponsor or the reporting condition of the user equipment 1 is satisfied.
Moreover, if the reporting condition is that the QoS of the service data flow is changed, when the QoS of the service data flow is changed, the PCEF apparatus 2 sends the reporting message to the online charging apparatus 3 such that the online charging apparatus 3 determines, based on the reporting message, whether the change of the QoS is initiated by the sponsor, and performs corresponding charging. The reporting message includes an event indicating that the QoS of the sponsor service data flow is changed, and changed QoS. How to determine whether the change of the QoS is initiated by the sponsor may be learned in the following several manners.
If the reporting message includes indication information used to indicate that an initiator of the change of the QoS is the sponsor, the online charging apparatus 3 may determine, according to the indication information, that the change of the QoS is initiated by the sponsor.
If the reporting message includes a particular rating group used to indicate that the change of the QoS of the service data flow is initiated by the sponsor, the online charging apparatus 3 may determine, according to the particular rating group, that the change of the QoS of the service data flow is initiated by the sponsor.
In step 619, if the change of the QoS is initiated by the sponsor, the online charging apparatus 3 writes the event indicating that the QoS of the sponsor service data flow is changed, and the changed QoS into a call detail record. The change of the QoS is not used as a charging factor for the user equipment 1. If the change of the QoS is not initiated by the sponsor, the online charging apparatus 3 uses the changed QoS as a charging factor for the user equipment 1, and the changed QoS is not used to generate the call detail record of the sponsor. The charging factor herein refers to a condition on which whether to charge a user is determined and a charging rate is determined.
Moreover, the reporting message includes one of the rating group, the sponsor identity, the application service provider identity, or the use information of the available credit quota corresponding to the sponsor identity and the application service provider identity, or a combination thereof. Therefore, the online charging apparatus 3 generates a call detail record based on the sponsor identity and the application service provider identity. The call detail record includes the sponsor identity, the application service provider identity, and the use information of the available credit quota corresponding to the sponsor identity and the application service provider identity. For example, the online charging apparatus 3 determines that charging process needs to be performed on the user equipment 1, and the online charging apparatus 3 performs charging process on the user equipment 1 based on the rating group and the use information.
If the reporting message includes the use information of use of the credit quota by the service data flow, the online charging apparatus 3 generates sponsor service data flow information according to the use information, and writes the sponsor service data flow information into the call detail record.
The use information includes the start time, the end time, and the effective use duration of using the credit quota by the service data flow in the current reporting period. The sponsor service data flow information also needs to include the start time, the end time, and the effective use duration of using the credit quota by the service data flow in the current reporting period.
Alternatively, if the use information does not include the start time or the end time of using the credit quota by the service data flow in the current reporting period, the online charging apparatus 3 considers a local time at which the online charging apparatus 3 sends the credit quota as the start time of the sponsor service data flow and considers a local time at which the online charging apparatus 3 receives the reporting message as the end time of the sponsor service data flow. In this way, the sponsor service data flow information may still include the start time and the end time of using the credit quota by the service data flow in the current reporting period. If the use information includes the effective use duration of using the credit quota by the service data flow in the current reporting period, the sponsor service data flow information also includes the effective use duration of using the credit quota by the service data flow in the current reporting period.
If the use information includes the sponsor identity, the sponsor service data flow information further includes the sponsor identity.
Another implementation scenario of this embodiment is described below. Referring to
In step 73, the PCEF apparatus 2 determines reporting levels of all effective PCC rules in the PCEF apparatus 2 are currently non-sponsor levels. In step 74, the PCEF apparatus 2 sends a reporting message to an online charging apparatus 3 such that the online charging apparatus 3 performs charging based on the reporting message and ends charging process on a service data flow. For details about how to perform charging according to the reporting message, refer to the foregoing content, and details are not described herein.
In conclusion, by means of the embodiments of the present disclosure, a sponsor may sponsor a service data flow of user equipment in an OCS. An online credit control user may use, in an online credit control process, traffic, duration, and a bandwidth that are sponsored by the sponsor. Furthermore, credit control may be performed on the user when the user and the sponsor share costs in order to effectively overcome disadvantages of the other approaches, and improve use efficiency of an OCS.
