[0026] For ease of understanding, the following describes some contents related to the embodiments of the present application.

[0027] A PIN is a group consisting of at least one PIN element, and at least one of the PIN elements is a terminal. There are three types of PIN elements: PINE, PEGC, and PIN Element with Management Capability (PEMC). One PINE is a terminal or a non-3GPP device. A non-3GPP device refers to a device that does not use certificates defined by 3GPP, does not support the Non-Access Stratum (NAS) protocol defined by 3GPP, or does not support 3GPP access technologies (e.g., 3G / 4G / 5G air interface technologies) but only supports non-3GPP access technologies (e.g., access technologies such as WiFi, fixed networks, and Bluetooth®).

[0028] PINEs can use network services and data through the PEGC access network, and PINEs have different functions (e.g., air conditioners, printers, etc.) and different QoS requirements for transmitted data. At the same time, PINEs may belong to different PINs. Considering that PINEs cannot communicate directly with the network, this requires PEGC to identify the traffic of different PINEs and provide differentiated traffic transmission to different PINEs.

[0029] The following describes in detail the traffic routing method, apparatus and device according to the embodiments of the present application through several embodiments and their application scenarios in conjunction with the drawings.

[0030] As shown in FIG. 2 , the traffic routing method of the embodiment of the present application includes:

[0031] In step 201, a first communication device obtains a first rule, where the first rule is used to establish the same or different data transmission channels for one or more PIN elements PINE of one Personal IoT Network PIN, and the first communication device and the one or more PINE are located within the same PIN; In step 202, the first communication device establishes a data transmission channel based on the first rule.

[0032] In this way, after obtaining the first rule through step 201, the first communication device can perform step 202, and establish the same or different data transmission channels for one or more PINE(s) in the PIN where it is located based on this first rule, realize differentiated traffic routing for different types of PINE, and ensure that elements in the PIN network use network services more efficiently and with higher quality.

[0033] It should be noted that in the embodiment of the present application, the first communication device may be a PEGC, and the data transmission channel is realized by a Protocol Data Unit (PDU) session, and the establishment of the data transmission channel may be understood as establishing a new PDU session to establish the data transmission channel, or selecting an appropriate PDU session from existing PDU sessions to establish the data transmission channel.

[0034] In some embodiments, optionally, the first rule includes a mapping relationship between PIN descriptors and protocol data unit (PDU) session parameters.

[0035] Here, the PIN description information is used to match a first rule that matches one or more PINE(s) of the data transmission channel to be established when the first communication device performs step 202. After matching the first rule to be used, the first communication device searches for corresponding PDU session parameters according to the mapping relationship therein, and establishes the data transmission channel.

[0036] The PDU session parameters may include a data network name (DNN), a single network slice selection assistance information (S-NSSAI), etc.

[0037] In some embodiments, optionally, when the first rule is used to establish the same data transmission channel for one or more PINE(s) of one PIN, the PIN description information is: PIN type and The service type and a PIN identifier; and first instruction information for instructing one or more PINE(s) to use the network service through the PIN gateway within one PIN.

[0038] Thus, by the first rule, The PIN type of the PIN is the PIN type included in the PIN description information; The service type of the PIN is the service type included in the PIN description information; The PIN includes a condition corresponding to a PIN identifier included in the PIN description information, and It is possible to establish the same data transmission channel for one or more PINE(s) that satisfy at least one of the conditions: a condition that the PINE is indicated by the first indication information of the PIN description information; and a condition that the PINE is indicated by the first indication information of the PIN description information.

[0039] Here, the PIN type is used to identify the type of a single PIN, and this type may be a major category such as personal entertainment, smart home, or sports and health, or a minor category such as sensor type, augmented reality (AR) / virtual reality (VR), smart lighting fixture, socket, or screen projection device. The service type is used to identify a service category, and different service types require different QoS, such as game type, office type, or home type. The PIN identifier (ID) is used to identify a single PIN or a single PIN group, and the PIN identifier may also be called a PIN group identifier.

[0040] The first indication information may be indicated by a PINE identifier, and the PINE identifier may be: The information may be at least one of a source Internet Protocol range (Source IP range), Service Set IDs (SSIDs), Bluetooth IDs (BT IDs), packet filters, port ranges, Media Access Control addresses (MAC addresses), and application IDs (APP IDs).

[0041] In some embodiments, optionally, when the first rule is used to establish different data transmission channels for one or more PINE(s) of a single PIN, the PIN description information is: The service type and Second indication information for indicating whether the PINE is an internal device or an external device; and third indication information for indicating one or more PINEs in the same group.

[0042] Thus, by the first rule, Establishing different data transmission channels for PINEs with different service types according to the service types included in the PIN description information; Establishing different data transmission channels for the internal PINE and the external PINE according to second instruction information included in the PIN description information; and establishing different data transmission channels for PINEs of different groups based on third instruction information included in the PIN description information.

[0043] Here, when the second instruction information indicates that a PINE is an internal device (also called an internal PINE), it indicates that this PINE is configured to the current PIN, and when the second instruction information indicates that a PINE is an external device (also called an external PINE), it indicates that this PINE is not configured to the current PIN, and this PINE is temporarily added to the current PIN. One or more PINEs in the same group indicated by the third instruction information satisfy the grouping requirements that the service types are similar and the QoS requirements are the same.

[0044] The second indication information and the third indication information may be indicated by a PINE identifier, and the specific implementation of the PINE identifier is as described above and will not be listed one by one here.

[0045] Optionally, the first rule is: URSP rules and and PIN routing rules.

[0046] That is, the URSP rule may be the first rule, or the PIN routing rule may be the first rule.

[0047] Optionally, the traffic description information of the URSP rule includes PIN description information.

[0048] That is, the URSP rule is the first rule, and its traffic description information should include PIN description information (the specific implementation of this PIN description information is as described above and will not be further described here), for example, as shown in Table 1 below:

[0049] [Table 1-A] [Table 1-B]

[0050] In some embodiments, the URSP rules are optionally used by the first communication device to establish or select an appropriate PDU session for traffic of one or more PINE(s) having the same QoS requirements.

[0051] For example, the URSP rules are as shown in Table 2:

[0052] [Table 2]

[0053] It should be noted that the first rule may be pre-configured and stored in the first communication device, and the first communication device performs step 201, i.e., retrieves the locally stored first rule.

[0054] Alternatively, the first rule is configured by other communication devices, and therefore, optionally, step 201 can be: receiving a URSP rule transmitted by the second communication device; receiving a PIN routing rule transmitted by a third communication device; and receiving the PIN routing rule transmitted by the fourth communication device.

[0055] Here, the second communication device may be a PCF, the third communication device may be an AMF, and the fourth communication device may be an SMF.

[0056] Optionally, the method further comprises: The first communication device further includes transmitting related information of the first communication device, where the related information of the first communication device includes: Capability information (PEGC capability) of the first communication device for indicating that the first communication device has gateway capability; The indication information of the first communication device includes indication information of the first communication device (PEGC indication) for identifying the first communication device; A policy container of the first communication device (PEGC UE policy request), wherein the policy container of the first communication device is used to request a URSP rule.

[0057] Here, the first communication device sends related information of the first communication device to the second communication device, so that the second communication device can determine and send URSP rules to the first communication device (for example, provide the URSP rules to the PEGC through a terminal configuration update process).

[0058] In response, the second communication device obtains related information of the first communication device and determines a URSP rule according to the related information of the first communication device, so that the first communication device can complete the establishment of a data transmission channel by taking the URSP rule as a first rule.

[0059] Optionally, the first communication device sends a registration request, wherein the registration request carries relevant information of the first communication device.

[0060] At this time, the second communication device is a PCF, and can obtain related information of the first communication device by receiving a first message, the first message including the related information of the first communication device carried in the registration request. The first message is sent by an AMF.

[0061] In some embodiments, optionally, if the registration request includes capability information of the first communication device, the capability information of the first communication device is included in a PIN gateway capability information field of a third information element, wherein the third information element includes at least one of a 5GS mobility management information element, a PIN gateway capability information element, and a 5GS update type information element; If the registration request includes a policy container of the first communication device, the policy container of the first communication device is included in a payload container information element, where the payload container type of the payload container information element is set as a terminal policy container or a PIN gateway policy container.

[0062] Optionally, a PEGC capability bit is added to the 5GS mobility management information element (5GMM capability IE), for example, a PIN element with gateway capability (PIN element with gateway capability) (octet X, bit Y), where '0' indicates that the gateway capability is not supported (PIN element with gateway capability not supported) and '1' indicates that the gateway capability is supported (PIN element with gateway capability supported). Alternatively, the PIN element with gateway capability IE may be a 5GS PIN feature support IE, the purpose of which is to indicate whether the UE supports a specific PIN feature. The encoding of the 5GS PIN feature support IE is as shown in Figure 3, and the 5GS PIN feature support IE is a fourth type of information element with a length of 3 octets. The PIN gateway capability information element may be as shown in Table 3 below:

[0063] [Table 3]

[0064] The purpose of the 5GS update type information element (5GS update type IE) is to allow the terminal to provide additional information to the network when performing the registration process. The encoding of the 5GS update type IE is as shown in Figure 4, and the 5GS update type IE is a fourth type of information element with a length of 3 octets. The 5GS update type IE may be as shown in Table 4 below:

[0065] [Table 4]

[0066] The PEGC UE policy request is included in a payload container information element, and the payload container information element, e.g., Payload container IE, may be a Payload container IE with the payload container type set to UE policy container (UE policy container), or may be a Payload container IE with the payload container type set to PIN gateway policy container (e.g., PEGC UE policy container, PIN policy container, etc.). The PIN gateway policy container is a newly added payload container type.

[0067] In some embodiments, optionally, the registration request includes, if the payload container type of the payload container information element is set to terminal policy container: capability information of the first communication device; and instruction information for the first communication device.

[0068] If the Payload container type IE of the registration request is set to "UE policy container" and the Payload container IE includes a terminal policy container of the first communication device, the registration request may further include a PEGC indication and / or a PEGC capability as described above.

[0069] Optionally, the registration request further comprises, if the payload container type of the payload container information element is set to PIN gateway policy container: a status indication message for the first communication device; and a status indication message of the PIN where the first communication device is located.

[0070] That is, when the Payload container type IE of the registration request is set to "PEGC UE policy container" or "PIN policy container" and the Payload container IE includes a terminal policy container of a first communication device, the registration request may further include a state indication message of the first communication device (PEGC UE STATE INDICATION message) and / or a state indication message of the PIN where the first communication device is located (PIN STATE INDICATION message).

[0071] Alternatively, after receiving the PEGC indication, the PCF may search for subscription information corresponding to the PEGC based on the PEGC indication. The PEGC indication may be implemented as any one of a Generic Public Subscription Identifier (GPSI), a Subscription Permanent Identifier (SUPI), and a PEGC ID. The PEGC indication may further include a PIN identifier.

[0072] In some embodiments, optionally, after receiving the related information of the first communication device sent by the PIN AF, which includes only the indication information of the first communication device, the PCF determines the URSP rule based on the indication information of the first communication device.

[0073] In some embodiments, optionally, the second communication device obtains the first information and determines a URSP rule based on the first information, and then sends the URSP rule to the first communication device (for example, provides the URSP rule to the PEGC through a terminal configuration update process), so that the first communication device can complete the establishment of the data transmission channel with the URSP rule as the first rule.

[0074] Optionally, the second communication device receives the first information transmitted by a fifth communication device, where the fifth communication device may be a PIN MF.

[0075] Optionally, the first information is: one or more PIN routing rules; and sixth instruction information for instructing the second communication device to obtain subscription information of the first communication device from a UDM and determine a URSP rule.

[0076] In this way, the PCF can determine the URSP rule based on one or more PIN routing rules in the first information. For example, a relationship between the PIN routing rule and the URSP rule is preset, and the PCF can search for the corresponding URSP rule from the relationship after learning one or more PIN routing rules. The PCF may inquire about subscription information of the first communication device from the UDM based on the sixth instruction information in the first information, and determine the URSP rule based on the subscription information of the first communication device. Here, the subscription information may include the URSP rule, or a relationship between the subscription information and the URSP rule may be preset, and the PCF can search for the corresponding URSP rule from the relationship after learning the subscription information.

[0077] Here, the sixth indication information may include a PEGC identifier, and may further include a PEMC identifier or a PIN identifier.

[0078] In some embodiments, optionally, the second communication device obtains the second information and determines a PIN routing rule based on the second information, and then sends the PIN routing rule to the first communication device, so that the first communication device can complete the establishment of the data transmission channel with the PIN routing rule as the first rule.

[0079] Optionally, the second communication device obtains second information sent by a fifth communication device, which may be a PIN MF.

[0080] Optionally, the second information is: one or more PIN routing rules; seventh instruction information for instructing the second communication device to obtain subscription information of the first communication device from a UDM and determine a PIN routing rule; and and eighth instruction information for instructing the second communication device not to provide URSP rules.

[0081] In this way, the PCF may determine one or more PIN routing rules in the second information as PIN routing rules to be sent to the first communication device. The PCF may inquire about subscription information of the first communication device from the UDM based on the seventh instruction information in the second information, and determine the PIN routing rule based on the subscription information of the first communication device. Here, the subscription information may include the PIN routing rule, or a relationship between the subscription information and the PIN routing rule may be preset, and the PCF may be able to search for the corresponding PIN routing rule from the relationship after learning the subscription information.

[0082] The second information may further include eighth instruction information for instructing the second communication device not to provide instruction information for a URSP rule. In this way, after receiving the second information, the second communication device can determine a PIN routing rule based on the eighth instruction information and send the determined PIN routing rule to the first communication device, and there is no need to determine a URSP rule.

[0083] Optionally, if at least one of the first information and the second information does not include one or more PIN routing rules, the fifth communication device obtains PIN-related information; The fifth communication device determines the one or more PIN routing rules based on the PIN-related information.

[0084] The PIN-related information includes a PIN ID, a list of services, a PIN class, a time window, etc. The PIN MF generates a PIN routing rule based on the PIN-related information and a local configuration, where the local configuration is used as a PIN routing rule generation policy to generate a PIN routing rule based on the PIN-related information.

[0085] Alternatively, the PIN-related information may be conveyed when the PEGC or PEMC registers with the IN MF.

[0086] In some embodiments, optionally, after determining the URSP rule, the second communication device transmits the URSP rule to the first communication device, for example, the first communication device transmits the URSP rule via a terminal configuration update flow.
