[0044] Figure 1 FIG. 1 is a flow chart of a communication method according to some embodiments of the present disclosure. Figure 1As shown, the communication method is executed by a core network device, including steps S11 to S13.

[0045] Step S11: receiving a non-access stratum message sent by a user equipment.

[0046] In some embodiments, the communication method is executed by an access and mobility management function device in the core network. In addition, the communication method can also be executed by other network elements or function devices in the core network.

[0047] The non-access layer message carries an indication field of a connection service request and an indication field of a data service request.

[0048] In some examples, the non-access layer message is a protocol data unit (PDU) session establishment request message. In these examples, the indication field of the connection service request and the indication field of the data service request can be carried by an extended protocol configuration options in the PDU session establishment request message.

[0049] The indication field of the connection service request may include at least one of the following information: an identifier of the connection service, a type of the connection service, an area of ​​the connection service, and the like.

[0050] The indication field of the data service request may include at least one of the following information: the identifier of the data service, the type of the data service, the area of ​​the data service, etc. The type of the data service may be statistical analysis for registration or session, perception service, artificial intelligence (AI) service, etc. In addition, the indication field of the data service request may also include the quality of service (QoS) requirements of the requested data service, such as perception accuracy requirements, perception resolution requirements, perception service latency requirements, etc.

[0051] In some examples, the indication fields of the data service request include: dataServiceIdentifier, which indicates the representation of the data service request; dataServiceType, which indicates the type of the data service request; time, which indicates the time parameter of the data service, which may specifically include interval (this field indicates the time interval for data collection and reporting), start (this field indicates the time to start collection), duration field (this field indicates the duration of continuous service); region, which indicates the geographic location parameter of the data source.

[0052] In some other examples, the non-access layer message is a request message dedicated to the multi-factor service. For example, during the interaction between the user equipment and the core network, a NAS message dedicated to the multi-factor service request is added.

[0053] Step S12: Generate a service request according to the non-access layer message.

[0054] In some examples, the service request includes a connection service request and a data service request. In these examples, step S12 includes: extracting an indication field of the connection service request and an indication field of the data service request from the non-access layer message; generating a connection service request according to the indication field of the connection service request; generating a data service request according to the indication field of the data service request.

[0055] In other examples, the service request is a multi-factor service request, and the multi-factor service request is a composite request for a connection service and a data service. In these examples, step S12 includes: extracting an indication field of the connection service request and an indication field of the data service request from the non-access layer message; and generating a multi-factor service request according to the indication field of the connection service request and the indication field of the data service request.

[0056] Step S13: Send a service request.

[0057] The service request is used to trigger the connection service management function device and the data service management function device to provide the user equipment with connection service and data service.

[0058] In some examples, a connection service request and a data service request are generated through step S12. In these examples, step S13 includes: sending a connection service request to a connection service management function device to trigger the connection service management function device to provide a connection service for the user equipment; sending a data service request to a data service management function device to trigger the data service management function device to provide a data service for the user equipment.

[0059] In other examples, a multi-factor service request is generated through step S12. In these examples, step S13 includes: sending the multi-factor service request to the connection service management function device, and forwarding the multi-factor service request to the data service management function device through the connection service management function device to trigger the connection service management function device to provide connection services for the user equipment, and triggering the data service management function device to provide data services for the user equipment.

[0060] In some embodiments, the communication method further includes: before step S13, selecting a connection service management function device and a data service management function device according to a non-access layer message.

[0061] In some examples, when the indication field of the connection service request includes the area of ​​the requested connection service and the indication field of the data service request includes the area of ​​the requested data service, based on the area of ​​the requested connection service, a candidate connection service management function device of the corresponding area is selected from multiple candidate connection service management function devices as the connection service management function device; based on the area of ​​the requested data service, a candidate data service management function device of the corresponding area is selected from multiple candidate data service management function devices as the data service management function device.

[0062] For example, if the area of ​​the requested connection service and the area of ​​the requested data service are both area A, the candidate connection service management function device located in area A will be used as the connection service management function device, and the candidate data service management function device located in area A will be used as the data service management function device.

[0063] In other examples, the connection service management function device and the data service management function device are selected based on information such as the type and area of ​​the requested connection service, the type and area of ​​the requested data service, etc.

[0064] In the embodiment of the present disclosure, by selecting appropriate connection service management function equipment and data service management function equipment in advance according to the non-access layer message, it helps to reduce the communication delay in the subsequent establishment of connection and provision of data services, and better meet the business needs of users.

[0065] In the embodiments of the present disclosure, on the one hand, by carrying the indication field of the connection service and the indication field of the data service in the NAS message sent by the user equipment, the user equipment can request two services at the same time through one message, saving signaling overhead and reducing service delay; on the other hand, by generating a service request according to the NAS message by the core network device, and triggering the connection service management function device and the data service management function device in the core network to provide the user equipment with the connection service and the data service, the coordinated processing of the connection service and the data service is realized, and the signaling overhead and communication delay required for the core network to provide the connection service and the data service are reduced.

[0066] Figure 2 is a schematic diagram of a communication system architecture according to some embodiments of the present disclosure. Figure 2 As shown, the communication system architecture mainly includes user equipment 201, a wireless access network 202, and equipment in a core network.

[0067] The user equipment 201 , for example, is various terminal devices having a wireless communication function and supporting users to access network services.

[0068] The radio access network device 202 is a RAN (Radio Access Network) device. For example, the radio access network device 202 is a device that provides services such as radio access control and data transmission for user equipment in a specific area, and supports wireless sensing of a specific area or target and acquisition of sensing measurement data.

[0069] The core network equipment includes an access and mobility management function 203 , a connection service management function 204 , a data service management function 205 , a service exposure function 206 , a user plane function 208 , a data plane function 210 , and a data storage function 211 .

[0070] The access and mobility management function 203, in addition to being responsible for user equipment access and mobility management, also has the ability to coordinate processing of multiple element services such as data services and connection services.

[0071] Connection service management function 204: mainly responsible for control functions such as session establishment, modification, and release between users and the network.

[0072] Data service management function 205: mainly responsible for generating various data service tasks according to data service requirements, selecting network functions with different data capabilities such as data plane functions and data storage functions, forming executable logical topology, and controlling the work chain to implement specific data service functions. Data service management function 205 can also support data service capability reporting function.

[0073] The service opening function 206 is mainly responsible for opening the network capability to the application function 207 through the application program interface so as to respond to the business needs of the third party in a timely manner.

[0074] The user plane function 208 is mainly responsible for processing and forwarding user data, such as forwarding user plane data packets to the data network 209 .

[0075] Data plane function 210: mainly responsible for data collection, transmission, preprocessing, analysis and other functions.

[0076] Data storage function 211: mainly responsible for storing collected data and processing results of data services, etc.

[0077] Figure 3 is a flow chart of a communication method performed by multiple parties according to some embodiments of the present disclosure. Figure 3 In the embodiment shown, the communication method is Figure 2 Multiple functional devices in the illustrated architecture execute together, specifically including steps 301 to 307 .

[0078] Step 301: The user equipment sends a NAS message to the access and mobility management function.

[0079] Among them, the NAS message carries the indication field of the connection service and the indication field of the data service. There are two specific implementation methods for the NAS message. In one implementation method, an existing NAS message for a PDU session (such as a new PDU session request) is selected to carry the indication field of the connection service and the indication field of the data service. In another implementation method, a NAS message based on a newly added dedicated multi-factor service request carries the indication field of the connection service and the indication field of the data service.

[0080] Step 302: The access and mobility management function, the connection service management function, and the data service management function jointly process the multi-factor service request.

[0081] Step 302 may be implemented in two ways. In one implementation, the access and mobility management function disassembles and translates the NAS message into separate connection service requests and data service requests, and sends the connection service request to the selected connection service management function and the data service request to the selected data service management function. For example, the implementation is as follows: Figure 4 As shown in step 404 and step 405, Figure 6 As shown in step 604 and step 605 in .

[0082] In another implementation, the access and mobility management function disassembles and translates the NAS message to generate a multi-factor service request, and then sends the multi-factor service request to the connection service management function to process the connection service request message therein, and then the connection service management function forwards the multi-factor service request to the data service management function to process the data service request message therein. For example, in this implementation, Figure 5 As shown in step 504 and step 505, Figure 7 As shown in step 704 and step 705 in .

[0083] Step 303: The connection service management function controls the establishment of a PDU session connection.

[0084] Step 304: The data service management function selects a data plane function and a data storage function.

[0085] In some examples, the data service management function selects appropriate data plane functions and data storage functions according to data service requirements (eg, business type, region, etc. of the requested data service).

[0086] Step 305: The data service management function sends the data service task to the data plane function and the data storage function.

[0087] For example, the data service management function sends a data collection and processing task to the selected data plane function, and sends a data storage task to the selected data storage function.

[0088] Step 306: The data plane function and the data storage function execute the data service task.

[0089] For example, the data plane function performs data collection and processing tasks, and the data storage function performs data storage tasks.

[0090] Step 307: The data storage function returns the data service result to the user device.

[0091] Step 307 can be implemented in two ways. In the first implementation, the data storage function sends a notification message of the completion of the data storage task to the data service management function; the data service management function sends the storage address information of the data service processing result carried in the notification message to the access and mobility management function; the access and mobility management function sends the storage address information of the data service processing result to the user equipment through a downlink NAS message. For example, this implementation is as follows Figure 4 As shown in steps 411 and 412, Figure 5 As shown in steps 511 and 512 in .

[0092] In the second implementation, the data storage function sends a notification message of the completion of the data storage task to the data service management function; the data service management function obtains the configuration address information of the user plane function from the connection service management function, and sends the configuration address information of the user plane function to the data storage function; the data storage function sends the data service processing result to the user plane function according to the configuration address information of the user plane function, so that the data service processing result is sent to the user equipment through the user plane function. For example, this implementation is as follows Figure 6 As shown in steps 611 to 613, Figure 7 As shown in steps 711 to 713 in .

[0093] Furthermore, in the second implementation manner, the user plane function may send the data service processing result to the user equipment based on the downlink data transmission channel corresponding to the PDU session connection.

[0094] In the embodiments of the present disclosure, the following technical effects can be achieved through the above process: 1. The above process can enable the network to process both connection and data service requests at the same time, saving the signaling overhead required for the network to provide multi-factor services to user devices and reducing service latency; by enabling the network to reuse the channel established by the connection service to transmit the data service processing results, there is no need to repeatedly establish a connection channel when sending the data service processing results, further reducing the signaling overhead required to provide multi-factor services to user devices; by simultaneously requesting both connection and data services through one NAS message, signaling overhead can be further reduced and service latency can be reduced.

[0095] The following combination Figures 4 to 7 right Figure 3 The communication method shown is further explained. Figure 4 As shown, in some other embodiments, the communication method includes steps 401 to 412.

[0108] 412: The access and mobility management function sends the data service result to the user equipment.

[0109] In this step, the access and mobility management function may send the data service result or the storage address of the data service result to the user equipment through a downlink NAS message.

[0110] In the disclosed embodiment, the above process enables the network to simultaneously process the connection request and data service request of the user equipment, saving the signaling overhead of multi-factor service requests and reducing service delay.
