20250158954
This application belongs to the field of wireless communication technologies, and specifically, to a rule processing method, a communication device, and a network side device.
In the related art, a first device that accesses the non-3rd generation partnership project (3GPP) may interact with a second device (which may be referred to as a control gateway) through a non-3GPP access technology, thereby communicating with a network side via the second device. For example, in the personal internet of things, personal internet of things devices (where household devices are used as an example, such as a television, an air conditioner, and a sweeping robot) can access a network via a control gateway in the personal internet of things. The personal internet of things devices access the control gateway through technologies such as Bluetooth and Wi-Fi, and the control gateway then accesses a network through the 3GPP technology. This allows the personal internet of things devices to access the network through the control gateway to obtain network services and data. The control gateway in the personal internet of things may be a gateway in a smart home scenario, which may appear in the form of User Equipment (UE) with authentication of an operator.
In this application, a scenario in which different first devices may access the network via the same second device is considered. For example, in the personal internet of things, a speaker, a television, and a sweeping robot may access the network via the same UE. However, functions of different first devices may be different, and the first device that accesses the network via the second device needs to obtain related address information and/or perform differentiated processing on data of different functions, to ensure that data of the first device can be successfully transmitted and processed through the personal internet of things.

Apparently, the described embodiments are merely some rather than all of embodiments of this application. All other embodiments obtained by a person of ordinary skill in the art based on embodiments of this application shall fall within the protection scope of this application.
In the specification and claims of this application, terms “first” and “second” are used to distinguish similar objects, but are not used to describe a specific sequence or order. It should be understood that the terms used in such a way is interchangeable in proper circumstances, so that embodiments of this application can be implemented in other sequences than the sequence illustrated or described herein. In addition, objects distinguished by “first” and “second” are usually of a type, and the number of objects is not limited. For example, a first object may be one or more than one. In addition, in the specification and claims, “and/or” means at least one of the connected objects, and the character “/” generally indicates an “or” relation between associated objects.

The terms “system” and “network” in embodiments of this application are often used interchangeably, and the described technologies may be used both for the systems and radio technologies mentioned above and may also be used for other systems and radio technologies. The following descriptions describe a New Radio (NR) system for the objective of being used as an example, and NR terms are used in most of the descriptions below. However, these technologies may also be applied to applications other than NR system applications, such as a 6th Generation (6G) communication system.
However, currently in the related art, it cannot be ensured that the data of the first device can be successfully transmitted and processed through the personal internet of things.
Embodiments of this application provide a rule processing method, a communication device, and a network side device, to resolve a technical problem that the foregoing related art cannot ensure that a first device can successfully implement data transmission and processing through a personal internet of things.
In the embodiments of this application, in a scenario in which the second device interacts with the first device through the non-3GPP access technology, the first device receives the first information from the network side, and the first information includes the first mapping rule and/or the first allocation rule. The first device may forward, based on the first information, the data sent by the second device to the network side device and/or allocate the IP address to the second device and/or send the IP address to the second device. In this way, the first device may route data sent by different accessed second devices and/or allocate IP addresses to different accessed second devices, so that the first device can effectively implement data transmission and processing through the personal internet of things.
The rule processing solution provided in embodiments of this application is described in detail below by using some embodiments and application scenarios with reference to the accompanying drawings.
S310: A first device receives first information sent by a first network function, where the first information includes at least one of the following: a first mapping rule or a first allocation rule.
In the embodiments of this application, the first information is used by the first device to perform a first operation based on the first information, where the first operation includes at least one of the following:
In the embodiments of this application, after the first device receives the first information, when receiving the data sent by the second device to the network side device, the first device may forward the data to the network side device based on the first mapping rule. For example, the first device may transmit the data through a target Protocol Data Unit (PDU) based on the first mapping rule, where the target PDU is a PDU determined based on the first mapping rule.
In the embodiments of this application, the first mapping rule may include one or more.
In the embodiments of this application, the first network function may be a network element on a network side, for example, the first network function may be a PCF or a personal internet of things network management function (Personal IT Network management function, PINMF).
For example, the first mapping rule may include first session description information, and the first device may obtain, based on the first mapping rule, a target PDU that matches the first session description information.
In a possible implementation, the first session description information may include at least one of the following:
In a possible implementation, to correctly route data sent by different second devices, the first mapping rule may further include an association relationship between first association information and the first session description information, where the first association information may include at least one of the following:
The first mapping rule may include an association relationship between the foregoing at least one item and the first session description information.
In a possible implementation, the transmitting, by the first device, the data through a target PDU session based on the first mapping rule may include: transmitting, by the first device, the data through the target PDU session based on the first mapping rule and data attribute information of the data, where the target PDU session corresponds to the first session description information. For example, the first device may obtain, according to the first mapping rule, first session description information that matches the data attribute information of the data, and transmit the data through the target PDU session corresponding to the obtained first session description information.
In the foregoing possible implementation, corresponding to the first association information, the data attribute information includes but is not limited to at least one of the following:
In a possible implementation, the first mapping rule may further include priority information, the priority information indicates a priority of the first mapping rule, and when there are a plurality of first mapping rules, the first device uses the first mapping rule based on priorities of the first mapping rules. For example, when there are a plurality of first mapping rules, and when forwarding the data of the second device, the first device may first select a first mapping rule with a highest priority in descending order of a priority. If the first mapping rule does not include the first session description information associated with the data attribute information of the to-be-forwarded data, a first mapping rule with a second highest priority may be used. Based on the first mapping rule with the second highest priority, the first session description information associated with the data attribute information of the to-be-forwarded data is obtained. Alternatively, a correspondence between related information of the second device and the priority may be set, and the first device may select, according to the related information of the second device, such as a connection manner and a service type, a first mapping rule with a corresponding priority to forward the data of the second device.
In one or more of the foregoing possible implementations, the target PDU session may be an established target PDU session or a newly established target PDU session. For example, when the first device forwards the data of the second device, if the target PDU session corresponding to the first session description information has been established currently, the to-be-forwarded data is transmitted through the target PDU session. If the target PDU session corresponding to the first session description information has not been established currently, the target PDU session is established and the to-be-forwarded data is transmitted through the newly established target PDU session.
In the embodiments of this application, after the first device receives the first information, when the IP address needs to be allocated to the second device, the IP address may be allocated to the second device and/or the IP address may be sent to the second device based on the first allocation rule. For example, after registering with a personal internet of things management function (PINMF), the first device may receive the first information, and then allocate the IP address to the second device that accesses the first device and/or send the IP address to the second device. For example, the first device may first allocate the IP address to the second device according to the first allocation rule and send the IP address to the second device, or the first device may determine the IP address to be sent to the second device according to the first allocation rule and send the IP address to the second device.
In a possible implementation, the first allocation rule includes dynamic host configuration protocol DHCP service address information or at least one of the following:
The address mapping information includes any one of the following:
Through the foregoing possible implementation, corresponding IP addresses may be allocated to different second devices and/or corresponding IP addresses may be sent based on the first allocation rule, to facilitate subsequent management of the second devices.
In a possible implementation, when the first allocation rule includes the DHCP service address information, that the first device performs the first operation based on the first allocation rule may include: forwarding, by the first device, a DHCP message sent by the second device to a DHCP server indicated by the DHCP service address information, or forwarding a DHCP message sent by a DHCP server to the second device. For example, after receiving the DHCP message sent by the second device, the first device forwards the DHCP message to the DHCP server indicated by the DHCP service address information, and the DHCP server allocates the IP address to the second device and/or sends the IP address to the second device. Alternatively, the second device sends the DHCP message to the DHCP server. After allocating the IP address to the second device, the DHCP server returns the DHCP message to the first device. The first device determines that the DHCP server that sends the DHCP message is the DHCP server indicated by the DHCP service address information, and forwards the DHCP message to the second device. Through this possible implementation, the DHCP service address information is included in the first allocation rule, so that the DHCP server may allocate the IP address to the second device and/or send the IP address to the second device.
Through the technical solution provided in the embodiments of this application, the first device can map the data of different second devices to the corresponding PDU sessions, to correctly route the data. In addition, the first device may further implement allocation and/or sending of the IP address of the second device.
In the embodiments of this application, the first information received by the first device may be sent by the first network function (for example, the PCF or the PINMF). Based on the same concept of the embodiments of this application, the embodiments of this application further provide another rule processing method.
S410: A first network function sends first information to a first device, where the first information includes at least one of the following: a first mapping rule or a first allocation rule.
In the embodiments of this application, the first mapping rule instructs the first device to forward, based on the first mapping rule, data sent by a second device to a network side device; the first allocation rule instructs the first device to allocate, based on the first allocation rule, an IP address to the second device and/or send the IP address to the second device; and the second device interacts with the first device through a non-3GPP access technology.
The first information is the same as the first information in the method 300. For details, refer to related descriptions in the method 300.
In a possible implementation, the first allocation rule includes DHCP service address information or at least one of the following:
In a possible implementation, when the first allocation rule includes the DHCP service address information, the DHCP service address information is related to the first network function, and the method further includes: performing, by the first network function, a second operation based on information related to the second device, where the second operation includes at least one of the following:
For example, if the first network function has a DHCP server function or the first network function and the DHCP server are in a same merged network element, the first network function includes the DHCP service address information in the first allocation rule, that is, the DHCP service address information indicates the first device to forward a DHCP message sent by the second device to a DHCP server (where the DHCP server is the first network function in this possible implementation) corresponding to the DHCP service address information or to forward the DHCP message sent by the DHCP server corresponding to the DHCP service address information to the second device. In addition, the first network function may allocate the IP address to the second device and/or send the IP address to the second device according to information related to the second device, such as one or more of the MAC address of the second device, supported service information, a recommended QoS requirement, device type information, and the like.
When the first network function does not have the DHCP server function or the first network function and the DHCP server are respectively set in independent network elements, the first network function includes the DHCP service address information in the first allocation rule, that is, the DHCP service address information indicates the first device to forward the DHCP message sent by the second device to the DHCP server corresponding to the DHCP service address information or forward the DHCP message sent by the DHCP server corresponding to the DHCP service address information to the second device. When receiving a first address obtaining request from a third network function (the DHCP server), the first network function allocates the IP address to the second device according to the information related to the second device and returns the IP address to the third network function.
In a possible implementation, the first network function may also perform the second operation based on the information related to the second device and with reference to the first mapping rule. For example, the first network function may determine, based on information related to the second device and with reference to the first mapping rule, first session description information corresponding to the data of the second device, and allocate the IP address to the second device and/or send the IP address to the second device according to the first session description information.
For example, when the first network function has the DHCP server function or the first network function and the DHCP server are in a same merged network element, the first network function may determine, after receiving a DHCP message of a PIN device, a type of the PIN device and one or more of a corresponding DNN/network slice, an IP range, and the like according to a MAC address of the PIN device, and then send an IP address or an IP range of the PIN device to the PIN device according to the information.
When the first network function does not have the DHCP server function or the first network function and the DHCP server are respectively set in the independent network elements, the first network function may receive the first address obtaining request from the third network function (the DHCP server). The first address obtaining request includes MAC addresses of one or more PIN devices. The first network function determines a type of the PIN device, and at least one of a corresponding DNN/network slice, an IP range, and the like based on the MAC address, and then sends a first address obtaining request reply to the third network function according to the information. The reply message includes the IP address or the IP range of the PIN device.
In a possible implementation, the first mapping rule may include first session description information, and the first session description information includes at least one of the following:
In a possible implementation, the first mapping rule further includes an association relationship between first association information and the first session description information, and the first association information includes at least one of the following:
In a possible implementation, the first mapping rule further includes priority information, the priority information indicates a priority of the first mapping rule, and when there are a plurality of first mapping rules, the first device uses the first mapping rule based on priorities of the first mapping rules.
The first mapping rule in the embodiments of this application is the same as the first mapping rule in the method 300. For details, refer to related descriptions in the method 300.
In a possible implementation, before S410, the method may further include: receiving, by the first network function, second information from a second network function, where the second information includes at least one of the following:
In a possible implementation, the second mapping rule may include second session description information, and the second session description information includes one of the following:
In a possible implementation, the second mapping rule further includes an association relationship between second association information and the second session description information, and the second association information includes at least one of the following:
In a possible implementation, the second mapping rule further includes priority information, the priority information indicates a priority of the second mapping rule, and the first network function determines a priority of the corresponding first mapping rule based on a priority of each second mapping rule. In other words, one second mapping rule may determine one first mapping rule, and the priority of the first mapping rule corresponds to the priority of the corresponding second mapping rule.
In a possible implementation, when the second session description information includes the default value, that the first network function sends the first mapping rule to the first device based on the second mapping rule includes: determining, by the first network function according to a local policy, the first session description information corresponding to the second association information in the second information; and sending, by the first network function, the first mapping rule to the first device, where the first mapping rule includes the determined first session description information and/or the association relationship between the first session description information and the first association information (where in this possible implementation, the first association information is the second association information in the second information).
For example, the second session description information in the second mapping rule includes Default, and the first network function may determine, according to a local policy, a DNN and/or a network slice (for example, S-NSSAI) corresponding to the second association information in the second mapping rule.
In a possible implementation, when the second session description information includes the external slice information, that the first network function sends the first mapping rule to the first device based on the second mapping rule includes: obtaining, by the first network function, first session description information associated with the external slice information; and sending, by the first network function, the first mapping rule to the first device, where the first mapping rule includes the obtained first session description information and/or the association relationship between the obtained first session description information and the first association information (where in this possible implementation, the first association information is the second association information in the second information).
For example, the first network function may determine the first session description information (for example, the DNN and/or the network slice (the S-NSSAI)) by using the DNN/S-NSSAI associated with the external slice ID. The association relationship between the external slice ID and the DNN/S-NSSAI may be pre-configured in the first network function.
In a possible implementation, when the second information includes the mapping rule indication, that the first network function obtains the first mapping rule corresponding to the target identifier may include: sending, by the first network function based on the mapping rule indication in the second information, a mapping rule obtaining request carrying the target identifier to the third network function, and obtaining a mapping rule obtaining request reply sent by the third network function. The mapping rule obtaining request reply carries the first mapping rule corresponding to the target identifier.
For example, the first network function may send a PIN mapping rule obtaining request to UDR. The PIN mapping rule obtaining request includes a PEGC identifier, a PEMC identifier, or a group identifier, and may further include the external slice ID. The UDR receives the PIN mapping rule obtaining request, queries subscription information corresponding to the PEGC, the PEMC, or the group, takes into account a subscription relationship mapped between the PEGC identifier or the group identifier and the external slice ID, determines the PIN mapping rule or auxiliary information of the PIN mapping rule, and sends a PIN mapping rule obtaining request reply. The first network function receives the PIN mapping rule obtaining request reply of the UDR. The reply includes one or more PIN mapping rules or the auxiliary information of the PIN mapping rule. The auxiliary information includes the DNN/S-NSSAI and association information associated with the DNN/S-NSSAI.
Alternatively, when the second information includes the mapping rule indication, the first network function may also obtain, according to a local policy or pre-configuration information, the first mapping rule corresponding to the target identifier.
Based on the same technical concept, the embodiments of this application further provide another rule processing method.

In a possible implementation, the second mapping rule further includes an association relationship between second association information and the second session description information, and the second association information includes at least one of the following:
In a possible implementation, the second mapping rule further includes priority information, the priority information indicates a priority of the second mapping rule, and the first network function determines a priority of the corresponding first mapping rule based on a priority of each second mapping rule.
In a possible implementation, when the first allocation rule includes the DHCP service address information, the DHCP service address information is related to the second network function, and the method may further include:
For example, if the second network function has a DHCP server function or the second network function and the DHCP server are in a same merged network element, the second network function includes the DHCP service address information in the first allocation rule, that is, the DHCP service address information indicates, through the first network function, the first device to forward a DHCP message sent by the second device to a DHCP server (where the DHCP server is the second network function in this possible implementation) corresponding to the DHCP service address information or to forward the DHCP message sent by the DHCP server corresponding to the DHCP service address information to the second device. In addition, the second network function may allocate the IP address to the second device and/or send the IP address to the second device according to information related to the second device, such as one or more of the MAC address of the second device, supported service information, a recommended QoS requirement, device type information, and the like.
When the second network function does not have the DHCP server function or the second network function and the DHCP server are respectively set in independent network elements, the second network function includes the DHCP service address information in the first allocation rule, that is, the DHCP service address information indicates, through the first network function, the first device to forward the DHCP message sent by the second device to the DHCP server corresponding to the DHCP service address information or forward the DHCP message sent by the DHCP server corresponding to the DHCP service address information to the second device. When receiving a first address obtaining request from a third network function (the DHCP server), the first network function allocates the IP address to the second device according to the information related to the second device and returns the IP address to the third network function.
In a possible implementation, the second network function may also perform the third operation based on the information related to the second device and with reference to the second mapping rule. For example, the second network function may determine second session description information corresponding to the data of the second device based on the information related to the second device and with reference to the second mapping rule, and allocate the IP address to the second device and/or send the IP address to the second device according to the second session description information.
For example, when the second network function has the DHCP server function or the second network function and the DHCP server are in a same merged network element, the second network function may determine, after receiving a DHCP message of a PIN device, a type of the PIN device and one or more of a corresponding DNN/network slice, an IP range, and the like according to a MAC address of the PIN device, and then send an IP address or an IP range of the PIN device to the PIN device according to the information.
When the second network function does not have the DHCP server function or the second network function and the DHCP server are respectively set in the independent network elements, the second network function may receive the first address obtaining request from the third network function (the DHCP server). The first address obtaining request includes MAC addresses of one or more PIN devices. The second network function determines a type of the PIN device, and at least one of a corresponding DNN/network slice, an IP range, and the like based on the MAC address, and then sends a first address obtaining request reply to the third network function according to the information. The reply message includes the IP address or the IP range of the PIN device.
Through the technical solution provided in the embodiments of this application, data of different second devices may be mapped to corresponding PDU sessions, that is, the data of the second device is correctly processed; and in addition, the IP address of the second device may be further correctly allocated.
The following uses the personal internet of things as an example, to describe the technical solution provided in the embodiments of this application.
Step 601: A PEGC registers with a PINMF.
Step 602: The PINMF sends first information to a PCF.
The first information includes at least one of the following:
In the embodiments of this application, when the first information may include a plurality of PIN mapping rules, the plurality of PIN mapping rules have priorities. In addition, when the PIN mapping rules include default information, the first information includes only one PIN mapping rule.
Step 603: The PCF sends the PIN mapping rules to the PEGC.
In an implementation, when the first information includes one or more PIN mapping rules, and the PIN mapping rules do not include a default indication and an external slice/service identifier indication, the PCF forwards the first information to the PEGC.
In another implementation, when the PIN mapping rule included in the first information includes the default indication (that is, there is only one PIN mapping rule), the PCF determines the PDU session parameters (the DNN and the slice (the S-NSSAI)) of the PIN mapping rule, and sends the determined PIN mapping rule to the PEGC.
In still another implementation, when the PIN mapping rule included in the first information includes the external slice indication, the PCF determines the PDU session parameters (the DNN and the slice (the S-NSSAI)) in the PIN mapping rule by using the DNN/S-NSSAI associated with the external slice ID. An association relationship between the external slice ID and the DNN/S-NSSAI may be pre-configured in the PCF. The PCF sends the determined PIN mapping rule to the PEGC.
In still another implementation, when the first information includes the PIN mapping rule obtaining indication, in step 602, the PCF sends the PIN mapping rule obtaining request to the UDR. The PIN mapping rule obtaining request includes the PEGC identifier, the PEMC identifier, or the group identifier, may further include the external slice ID, and then receives a PIN mapping rule obtaining request reply from the UDR. The reply includes one or more PIN mapping rules or auxiliary information of the PIN mapping rules. The auxiliary information includes the DNN/S-NSSAI and association information associated with the DNN/S-NSSAI. In step 603, the PCF determines one or more PIN mapping rules according to reply information and sends the one or more PIN mapping rules to the PEGC. Alternatively, the PCF may also determine the one or more PIN mapping rules according to a local policy or pre-configuration information and send the one or more PIN mapping rules to the PEGC.
Step 604: The PEGC receives the PIN mapping rules sent by the PCF, and maps data of the PINE to a correspondingly matching PDU session according to the PIN mapping rule. If there is no matching PDU session currently, the PEGC establishes a new PDU session based on the PIN mapping rule.
Step 701: A PEGC registers with a PINMF.
Step 702: The PINMF sends second information to a PCF, where first information includes PIN address allocation information (PIN Address Allocation Info), and the PIN address allocation information includes at least one of the following:
Step 703a: When the PIN address allocation information includes the IP range, the PEGC allocates the IP address to the PINE based on the IP range.
Step 703b: When the PIN address allocation information includes the DHCP server address, the PEGC forwards the DHCP message of the PINE to a corresponding DHCP server address according to the PIN address allocation information.
Step 801: A PEGC registers with a PINMF.
In the embodiments of this application, the PINMF and a DHCP server are co-deployed.
Step 802: The PINMF receives an IP address request (carrying a MAC address) sent by a PINE via a DHCP message.
Step 803: The PINMF determines a type of the PIN device, and information such as a corresponding DNN/slice, an IP range, and the like according to the MAC address of the PIN device, and then sends an IP address or an IP range of the PIN device to the PIN device.
Step 901: A PEGC registers with a PINMF.
A difference between this method and the method 800 is that in this method, the PINMF and a DHCP server are not co-deployed but are independent network elements.
Step 902: The DHCP server receives an IP address request from a PINE, where the request carries a MAC address.
Step 903: The DHCP server sends a first address obtaining request to the PINMF, where the request carries the MAC address of the PINE.
Step 904: The PINMF determines a type of the PIN device, and information such as a corresponding DNN/slice, an IP range, and the like according to the MAC address of the PIN device, and then sends a first address obtaining request reply to the DHCP server, where the reply carries an IP address or an IP range of the PIN device.
Step 905: The DHCP server sends the IP address or the IP address range of the PIN device to the PIN device.
