Optionally, the core network may include at least one access network element, and the target access network element may be any access network element. In practical applications, the target access network element may have a non-third generation partnership project access function.

In one implementation, the remote ue may pre-train an algorithm model, and then input the access network element selection information into the algorithm model, where the algorithm model outputs the target access network element determined from the core network.

In another implementation manner, the remote user equipment may further perform matching processing on the access network element selection information and network element information of each network element in the core network, and screen the target access network element from the core network according to the matching result. Alternatively, the network element information may include configuration information, location information, function information, etc. of the network element. In the embodiment of the present application, the core network may be understood as a network side.

The network element corresponding to the network element information matched with the access network element selection information can be determined as a target access network element, and further, the remote user equipment can access the target access network element through the proximity service.

Specifically, the remote user equipment accesses to the target access network element through the proximity service, which can be understood as that the remote user equipment communicates with the core network through the target relay equipment, and can also be understood as including direct communication between the remote user equipment and the target relay equipment and direct communication between the remote user equipment and the core network through the target relay equipment.

Alternatively, the target relay device may be a layer 2 ue to core network function relay user device, a layer 3 ue to core network function relay user device supporting access of a non-third generation partnership project interworking function, or a layer 3 ue to core network function relay user device not supporting access of a non-third generation partnership project interworking function, etc.

In the embodiment of the application, in order to enable the method to be suitable for the scene of 2G, 3G, 4G or 5G, namely to improve the wide applicability of the network access mode identification method, the target relay equipment can be relay user equipment supporting the function from layer 3 user equipment accessed by the non-third generation partnership project interworking function 5G to the core network function. In the embodiment of the application, the target relay device can identify any relay user device in the system for the network access mode.

S103, sending the remote user equipment information to the target access network element. The remote user equipment information is used for indicating the target access network element to trigger the management function network element to identify the network access mode of the remote user equipment.

Optionally, the remote user equipment information may be understood as a message that the access network element controls other network elements in the core network to perform service processing; the remote user equipment information may include data information, control signaling, and the like.

Illustratively, the remote ue information may be an uplink Non-Access Stratum (NAS) message, or the like, and may also be N2 port, N3 port, or N4 port signaling, or the like.

In practical application, after the remote user equipment determines the target access network element, the non-third generation partnership project access function of the target access network element can be opened, and then the remote user equipment sends the remote user equipment information to the target access network element through the target relay equipment.

In practical application, the core network needs to identify that the network access mode of the remote user equipment is a proximity service access mode, and then can realize the application of different subsequent network traffic management. Specifically, the remote user equipment information may be sent to the target access network element, and correspondingly, after the target access network element receives the remote user equipment information, the target access network element may trigger the management function network element to identify the network access mode of the remote user equipment.

The management network element may be a session management function network element in the core network, or an access and mobility management function network element.

The network access mode of the remote user equipment is identified, which can be understood as the network access mode of identifying the target access network element accessed by the remote user equipment.

Specifically, after receiving the remote user equipment information, the target access network element may send a network access mode determining parameter to the access and mobility management function network element, and the session management network element or the access and mobility management function network element identifies the network access mode according to the network access mode determining parameter; optionally, the network access manner determining parameter may include information such as a transmission speed, a transmission distance, an information sender, and the like of the remote user equipment information.

It should be noted that, if the session management network element performs the identification operation, the access and mobility management function network element may send the received network access manner determining parameter to the session management network element to instruct the session management network element to perform the identification operation.

The manner of executing the identification operation by the network element with the triggering management function may be direct triggering or indirect triggering, which is not limited to the embodiment of the present application. It should be noted that, if the target access network element triggers the access and mobility management function network element to perform the identification operation, the method may be referred to as direct triggering; if the target access network element triggers the session management function network element to perform the identification operation, that is, when the target access network element triggers the session management function network element to perform the identification operation through the access and mobility management function network element, the method may be referred to as indirect triggering.

In the embodiment of the application, after the management function network element recognizes that the network access mode of the remote user equipment is the adjacent service access mode, the session management function network element can be further triggered to successfully distinguish and manage different network flows generated in other information sending processes, so that the problem that the different flows cannot be distinguished and managed in the traditional technology is solved, and the different flows can be distinguished and managed, and differentiated charging of the different flows by the core network and service management and policy control of the remote user equipment by the core network can be further facilitated. Wherein, the sending of the other information refers to the process that the remote user equipment sends the other information to the target access network element; other information may also be data information, control signaling, etc.

It should be noted that, the subsequent management of different network traffic generated in the other information sending process may be understood as a process of distinguishing and managing the adjacent traffic and the normal traffic used in the other information sending process when the remote user equipment accesses the target access network element through the target relay device.

When the ProSe is used for representing the proximity service, the proximity service flow may include ProSe flow used by the remote user equipment to send other information to the target access network element, and ProSe flow contributed by the target relay device in the process that the remote user equipment sends other information to the target access network element; the normal traffic may include traffic used by the target relay device to access the target access network element through the non-ProSe during the process of the remote user device sending other information to the target access network element.

In practical application, if the network access mode is identified as the adjacent service access mode by the access and mobility management function network element, the relevant information of the identified adjacent service access mode can be sent to the session management network element, so as to trigger the session management network element to manage different network flows generated in other information sending processes subsequently; if the session management function network element recognizes that the network access mode is the proximity service access mode, the session management function network element can automatically trigger the subsequent management of different network flows generated in other information sending processes.

In addition, the network traffic management may include performing fine-grained statistics, analysis and/or storage on different types of network traffic, where differentiated charging of different traffic by the core network may be further facilitated according to different network traffic statistics results, and service management and policy control of the remote user equipment by the core network may be performed by the core network.

In the technical scheme of the embodiment of the application, access network element selection information is acquired, a target access network element is determined from a core network according to the access network element selection information, remote user equipment information is sent to the target access network element, and the target access network element is instructed to trigger a management function network element to identify a network access mode of the remote user equipment; the method can determine the specific access network element accessed to the remote user equipment through the access network element selection information, namely the target access network element, and when the target access network element receives the remote user equipment information, the target access network element can trigger the management function network element in the core network to identify the network access mode of the remote user equipment. Further, based on the identification of the network access mode of the remote user equipment, the core network can be triggered to successfully distinguish and manage different network flows, so that the wide usability of the network access mode identification method can be improved.

In some scenarios, the core network includes a plurality of access network elements, and a procedure for determining the target access network element from the core network is described below. In an embodiment, as shown in fig. 3, the step of determining the target access network element from the core network according to the access network element selection information in S102 may be implemented as follows:

s112, judging whether the access network element selection information comprises the selection identification of the access network element or not, and obtaining a judgment result.

Alternatively, the selection identifier of the access network element may be understood as an identifier required for selecting the target access network element from the core network; the selection identifier may include a configuration identifier, a function identifier, an attribute identifier, etc. of the access network element.

Specifically, the remote user equipment may determine whether the access network element selection information includes a selection identifier of the access network element, so as to obtain a determination result. Optionally, the judging result may include a selection identifier of the access network element in the access network element selection information, and may also include no selection identifier of the access network element in the access network element selection information.

S122, determining a target access network element from the core network according to the judging result and the access network element selection information.

Based on the judgment result obtained in the step S112, a corresponding selection policy may be selected, and then the corresponding selection policy is adopted to process the access network element selection information, and a target access network element is selected from the core network according to the processing result.

In addition, the mode of constructing the access network element identification address can also be the access network element identification address determined by the remote user equipment according to the attribute information of the access network element.

Further, an algorithm model may be trained, and then the access network element identification address and the access network element selection information are input into the algorithm model, and the algorithm model selects a target access network element from the core network and outputs the target access network element.

Or, the access network element identification address corresponding to the access network element identification address and the access network element selection information can be searched in the mapping relation, and the access network element corresponding to the searched access network element identification address is determined as the target access network element.

Correspondingly, the remote user equipment can receive the tracking area identification of the relay service cell and construct the identification address of the target relay equipment according to the tracking area identification of the relay service cell.

In an embodiment, the method for constructing the identification address of the target relay device according to the tracking area identifier of the relay service cell may be that the identification address of the relay user device corresponding to the tracking area identifier of the relay service cell is obtained from the mapping relationship, so as to obtain the identification address of the target relay device; the mapping relationship may include tracking area identifiers of different relay service cells, identification addresses of different relay user equipments, and a correspondence relationship between the two.

According to the technical scheme, whether the selection information of the access network element comprises the selection identification of the access network element is judged to obtain a judgment result, and a target access network element is determined from a core network according to the judgment result and the selection information of the access network element; the method can select the target access network element through the access network element selection information under the condition that the access network element selection information comprises or does not comprise the selection identification of the access network element, thereby improving the success rate of the target access network element selection, and simultaneously, on the basis of determining the target access network element, the network element triggering management function can be used for successfully identifying the network access mode of the remote user equipment through the target access network element.
