[0026] To facilitate understanding, the following describes some aspects of the embodiments of this application.

[0027] A PIN is a group consisting of at least one PIN element, of which at least one PIN element is a terminal. There are three types of PIN elements: PINE, PEGC, and PIN Element with Management Capability (PEMC). A single PINE is either a terminal or a non-3GPP device. A non-3GPP device is a device that does not use certificates defined by 3GPP, does not support Non-Access Stratum (NAS) protocols defined by 3GPP, or does not support 3GPP access technologies (e.g., 3G / 4G / 5G Air Interface technologies) and only supports non-3GPP access technologies (e.g., WiFi, fixed networks, Bluetooth®, etc.).

[0028] PINEs can use network services and data via the PEGC access network. However, PINEs have different functions (e.g., air conditioners, printers, etc.), different QoS requirements for transmitted data, and 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] In the following sections, the traffic routing method, apparatus, and equipment according to the embodiments of this application will be described in detail with reference to several embodiments and their application scenarios, accompanied by drawings.

[0030] As shown in Figure 2, the traffic routing method of the embodiment of this application includes the following:

[0031] In step 201, the first communication device acquires 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 a personal IoT network PIN, and the first communication device and the one or more PINEs 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 by step 201, the first communication device can perform step 202, establishing the same or different data transmission channels for one or more PINE(s) within the PIN where it is located based on this first rule, achieving differentiated traffic routing for different types of PINEs, and ensuring that elements within the PIN network use network services more efficiently and with higher quality.

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

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

[0035] Here, the PIN description information is used when the first communication device performs step 202 to match a first rule that fits one or more PINE(s) of the data transmission channel to be established. After matching with the first rule to be used, the first communication device retrieves the corresponding PDU session parameters by their mapping relationships and establishes the data transmission channel.

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

[0037] In some embodiments, if the first rule is selectively used to establish the same data transmission channel for one or more PINE(s) of a single PIN, the PIN description information is: PIN type, Service type and PIN identifier and It includes at least one of the following: first instruction information for instructing one or more PINE(s) to use network services via a PIN gateway within a single PIN.

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

[0039] Here, PIN type is used to identify a type of PIN, and this type may be a broad category such as personal entertainment, smart home, or sports health, or a subcategory such as sensor type, augmented reality (AR) / virtual reality (VR), smart lighting fixtures, sockets, or screen projection equipment. Service type is used to identify a service category, and different service types require different QoS levels, such as game type, office type, or home type. PIN identifier (ID) is used to identify a PIN or a group of PINs, and a PIN identifier may also be called a PIN group identifier.

[0040] The first instruction information may be indicated by a PINE identifier, and the PINE identifier is It may also include at least one of the following: Source Internet Protocol range (Source IP range), Service Set IDs (SSIDs), Bluetooth IDs (BT IDs), Packet filters, Port range, Media Access Control address (MAC address), and Application IDs (APP IDs).

[0041] In some embodiments, if the first rule is selectively used to establish different data transmission channels for one or more PINE(s) of a single PIN, the PIN description information is: Service type and Second instruction information to indicate whether PINE is an internal or external device, It includes at least one of the following: a third piece of information that points to one or more PINEs in the same group.

[0042] Thus, according to the first rule, Based on the service type included in the aforementioned PIN description information, different data transmission channels are established for PINEs with different service types. Based on the second instruction information contained in the aforementioned PIN description information, different data transmission channels are established for the internal PINE and the external PINE. Based on the third instruction information contained in the PIN description information, at least one of the following can be achieved: establishing different data transmission channels for different groups of PINEs.

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

[0044] The second and third instruction information may also be indicated by PINE identifiers, and the specific implementations of PINE identifiers are as described above and will not be listed one by one here.

[0045] Selectively, the first rule is, URSP rules and, It is at least one of the PIN routing rules.

[0046] In other words, the URSP rule may be the primary rule, or the PIN routing rule may be the primary rule.

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

[0048] In other words, the URSP rule should be the primary 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 explained further here). For example, as shown in Table 1 below:

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

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

[0051] For example, the URSP rule is as shown in Table 2:

[0052] [Table 2]

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

[0054] Alternatively, the first rule is comprised of other communication devices, and therefore, selectively, step 201 is, Receiving the URSP rule transmitted by the second communication device, Receiving PIN routing rules transmitted by a third communication device, This includes at least one of the following: receiving a PIN routing rule transmitted by a 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] Selectively, the above method, The first communication device further includes transmitting related information of the first communication device, wherein the related information of the first communication device is: Capability information (PEGC capability) of the first communication device for indicating that the first communication device has gateway capability, The instruction information for the first communication device includes the instruction information for the first communication device (PEGC indication) for identifying the first communication device, The policy container of the first communication device (PEGC UE policy request) is used to request URSP rules.

[0057] Here, the first communication device transmits relevant information of the first communication device to the second communication device, thereby enabling the second communication device to determine and transmit URSP rules to the first communication device (for example, by providing URSP rules to PEGC through a terminal configuration update process).

[0058] In response, the second communication device acquires relevant information from the first communication device and determines a URSP rule based on the relevant information from the first communication device. As a result, the first communication device can complete the establishment of a data transmission channel using the URSP rule as the first rule.

[0059] Selectively, the first communication device transmits a registration request, which carries relevant information of the first communication device.

[0060] At this time, the second communication device is a PCF, which can obtain relevant information of the first communication device by receiving the first message, and the first message includes relevant information of the first communication device being carried in this registration request. The first message is transmitted by an AMF.

[0061] In some embodiments, if the registration request optionally includes capability information for the first communication device, the capability information for the first communication device is included in the PIN gateway capability information field of the third information element, where 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 the policy container of the first communication device, the policy container of the first communication device is included in the payload container information element, where the payload container type of the payload container information element is set to either a terminal policy container or a PIN gateway policy container.

[0062] Selectively, a PEGC capability bit is added to the 5GS mobility management information element (5GMM capability IE), for example, to create a PIN element with gateway capability (octet X, bit Y), where "0" indicates that the PIN element does not have gateway capability (PIN element with gateway capability not supported) and "1" indicates that the PIN element has gateway capability (PIN element with gateway capability supported). Selectively, the PIN element with gateway capability IE may be a 5GS PIN feature support IE, whose purpose is to indicate whether the UE supports a particular 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 IE may be as shown in Table 3 below:

[0063] [Table 3]

[0064] The purpose of the 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 also be as shown in Table 4 below:

[0065] [Table 4]

[0066] The PEGC UE policy request is included in the payload container information element, and the payload container information element, for example, Payload container IE, may be a Payload container IE with the Payload container type set to terminal policy container (UE policy container), or it 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, the registration request is selectively made if the payload container type of the payload container information element is set to terminal policy container. The capability information of the first communication device, It includes at least one of the instruction information of 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 the terminal policy container of the first communication device, the registration request may further include the PEGC indication and / or PEGC capability as described above.

[0069] Selectively, the registration request is made if the payload container type of the payload container information element is set to a PIN gateway policy container. The status instruction message of the first communication device, The first communication device includes at least one of the following: a status indication message for the PIN where the first communication device is located.

[0070] That is, if 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 the terminal policy container of the first communication device, the registration request may further include a PEGC UE STATE INDICATION message and / or a PIN STATE INDICATION message for the PIN on which the first communication device is located.

[0071] Selectively, after receiving a PEGC indication, the PCF can retrieve subscription information corresponding to the PEGC based on the PEGC indication. The implementation method of the PEGC indication may be one of the following: a Generic Public Subscription Identifier (GPSI), a Subscription Permanent Identifier (SUPI), or a PEGC ID. The PEGC indication may further include a PIN identifier.

[0072] In some embodiments, selectively, the PCF receives relevant information of the first communication device, which includes only the instruction information of the first communication device transmitted by the PIN AF, and then determines a URSP rule based on this instruction information of the first communication device.

[0073] In some embodiments, the second communication device selectively acquires the first information and determines a URSP rule based on this first information. It then transmits this URSP rule to the first communication device (for example, by providing the URSP rule to the PEGC through a terminal configuration update process), thereby enabling the first communication device to complete the establishment of the data transmission channel with the URSP rule as the first rule.

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

[0075] Selectively, the first information is One or more PIN routing rules, The second communication device includes at least one of the following: a sixth instruction information for instructing the UDM to obtain subscription information for the first communication device from the UDM and determine the URSP rule.

[0076] In this way, the PCF can determine a URSP rule based on one or more PIN routing rules in this first information. For example, a relationship may be pre-established between PIN routing rules and URSP rules, and after knowing one or more PIN routing rules, the PCF can retrieve the corresponding URSP rule from this relationship. The PCF may query the UDM for subscription information of the first communication device based on the sixth instruction information in this first information, and determine a URSP rule based on the subscription information of the first communication device. Here, the subscription information may include URSP rules, or a relationship may be pre-established between the subscription information and URSP rules, and after knowing the subscription information, the PCF can retrieve the corresponding URSP rule from this relationship.

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

[0078] In some embodiments, the second communication device selectively acquires second information and determines a PIN routing rule based on that information. It then transmits this PIN routing rule to the first communication device, which can then use this PIN routing rule as the first rule to complete the establishment of the data transmission channel.

[0079] Selectively, the second communication device acquires the second information transmitted by the fifth communication device, which may be a PIN MF.

[0080] Selectively, the second piece of information is One or more PIN routing rules, A seventh instruction information for instructing the second communication device to obtain subscription information for the first communication device from the UDM and determine PIN routing rules, This includes at least one of the following: an eighth instructional piece of information indicating that the second communication device does not provide URSP rules.

[0081] In this way, the PCF may determine one or more PIN routing rules in this second information as PIN routing rules to be transmitted to the first communication device. Based on the seventh instruction information in this second information, the PCF may query the UDM for subscription information of the first communication device and determine PIN routing rules based on the subscription information of the first communication device. Here, the subscription information may include PIN routing rules, or a relationship may be pre-established between the subscription information and the PIN routing rules, and the PCF may retrieve the corresponding PIN routing rules from this relationship after knowing the subscription information.

[0082] The second information may further include an eighth instruction to indicate that the second communication device does not provide instruction information for URSP rules. In this way, after receiving the second information, the second communication device can determine a PIN routing rule based on the eighth instruction and transmit the determined PIN routing rule to the first communication device, without having to determine a URSP rule.

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

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

[0085] Selectively, the PIN-related information may be transmitted when PEGC or PEMC registers it in IN MF.

[0086] In some embodiments, the second communication device selectively determines the URSP rule and then 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.

[0087] In some embodiments, the second communication device may optionally, after determining the PIN routing rule, transmit the PIN routing rule to a third and / or fourth communication device, which then transmits the PIN routing rule to the first communication device.
