As mentioned in the background section, the current mobile network needs to support a method for switching paths between terminals from near-area communication to network communication. In the related art, when the near area communication is switched to the network communication between the terminals, service continuity cannot be guaranteed.

The inventors found that the path switching method for ProSe in the related art does not support the path switching method between terminals from proximity service communication to wireless access network communication, and there is no interface between the proximity service function and the session management function.

Based on the above problems, an embodiment of the present disclosure provides a method for converting near area communication to network communication, adding an interface between the proximity service function and the session management function, transmitting terminal session information and session management function information through the network, and controlling user The forwarding function connects the two sessions of the terminal, so as to realize the goal of ensuring business continuity after switching from short-distance business communication to wireless access network communication between terminals.

The present disclosure provides a method, device, device, and storage medium for switching from near-area communication to network communication, at least to a certain extent, solving the problem that business continuity cannot be guaranteed when terminals are switched from near-area communication to network communication in the related art question.

Other features and advantages of the present disclosure will become apparent from the following detailed description, or in part, be learned by practice of the present disclosure.

The near-field communication in the embodiments of the present disclosure may also be called a short-distance communication service, and may include D2D (Device To Device, device-to-device) communication. For ease of understanding, D2D communication is used as an example for near-field communication in the following description.

The method for converting near area communication to network communication provided in this disclosure may be applied to the network architecture shown in FIG. 1 , where the network architecture includes a first terminal 102 , a network device 104 and a second terminal 106 .

The first terminal 102 and the second terminal 106 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, Internet of Things devices or other processing devices connected to wireless modems, as well as various forms of user Equipment, mobile station (Mobile Station, MS), terminal (terminal device) and so on. For convenience of description, the devices mentioned above are collectively referred to as terminals.

The network device 104 may be a base station, and the base station may be a device deployed in an access network to provide a wireless communication function for a terminal. The base station may include various forms of macro base stations, micro base stations, relay stations, access points and so on.

In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in LTE systems, they are called eNodeB or eNB; in 5G NR-U systems, they are called gNodeB or gNB. .

In some scenarios, a "base station" may also be called a "cell".

As communications technology evolves, the description "base station" may change. For convenience, in the embodiments of the present disclosure, the foregoing devices that provide wireless communication functions for terminals are collectively referred to as network devices.

In the embodiment of the present disclosure, the first terminal 102 and the network device 104, and the second terminal 106 and the network device 104 communicate with each other through a certain air interface technology, such as a Uu interface.

In some embodiments, the first terminal 102 and the second terminal 106 communicate with each other through some communication technology.

Optionally, the first terminal 102 and the second terminal 106 may communicate through Bluetooth or WiFi technology.

Alternatively, the first terminal 102 and the second terminal 106 support device-to-device (Device to Device, D2D) communication, and sidelink (sidelink) communication can be performed between the first terminal 102 and the second terminal 106 through the PC-5 interface .

Wherein, the sidelink communication implements addressing through the source identifier and destination identifier of the MAC layer, that is, no connection needs to be established before the communication.

In the cellular system, when there is a service to be transmitted between the first terminal 102 and the second terminal 106, the service data from the first terminal 102 to the second terminal 106 will first be transmitted to the base station (Base Station) of the cell where the first terminal 102 is located through the air interface. Station, or eNB, or evolution), the base station transmits the user data to the base station of the cell where the second terminal 106 is located through the core network, and the base station transmits the above service data to the second terminal 106 through the air interface. The service data transmission from the second terminal 106 to the first terminal 102 adopts a similar processing flow.

When the first terminal 102 and the second terminal 106 are located in the same cell, although the two terminals are covered by the cell of the same base station, one data transmission still consumes two wireless spectrum resources.

If the first terminal 102 and the second terminal 106 are located in the same cell and are relatively close to each other, then the above cellular communication method is obviously not an optimal communication method.

Moreover, with the diversification of mobile communication services, for example, social networking, electronic payment, etc. are more and more widely used in wireless communication systems, so that the demand for service transmission between users in close proximity is increasing.

Based on the above requirements, the D2D communication mode is becoming more and more common in the service transmission scenario between users in a short distance. For example, the above-mentioned D2D communication solution may be adopted between the first terminal 102 and the second terminal 106 .

In the D2D communication solution, service data is directly transmitted from the source user equipment to the target user equipment through the air interface without being forwarded by the base station, which can also be called Proximity Service (ProSe for short).

This communication mode is different from that of traditional cellular systems. For short-distance communication users, D2D not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network.

D2D communication based on cellular network is a technology that directly communicates between multiple terminal devices that support D2D functions under the control of the system. It can reduce system resource occupation, increase the spectrum efficiency of cellular communication systems, and reduce terminal transmission power Consumption, and to a large extent save network operating costs.

Please continue to refer to FIG. 1. When the position of the first terminal 102 or the second terminal 106 changes, for example, the distance between the first terminal 102 and the second terminal 106 becomes larger, the effect of D2D communication will become worse. The first The terminal 102 and the second terminal 106 may not be able to communicate directly through the short distance service, so the two need to switch to network communication. The method for switching from near field communication to network communication provided by the embodiments of the present disclosure can be applied in this conversion process.

FIG. 2 shows a flow chart of a method for converting near-area communication to network communication in an embodiment of the present disclosure. As shown in FIG. 2 , the method for converting near-area communication to network communication provided in an embodiment of the present disclosure includes the following steps:

In step S202, the first proximity based service function node associates the session information of the second terminal with the session information of the first terminal when the first terminal and the second terminal need to switch from near area communication to network communication;

Step S204, the first proximity service function node sends the associated session information of the first terminal to the first session management function node;

Step S206, the session management function node controls the user forwarding function node, so that the user forwarding function node connects the session of the first terminal and the session of the second terminal based on the session information;

Step S208, the session management function node notifies the first terminal to switch to network communication;

Step S210, the session management function node notifies the second terminal to switch to network communication.

It should be noted that, in the embodiment of the present disclosure, a communication interface needs to be set between the proximity service function node and the session management function node.

When the terminals switch from near-distance service communication to each terminal establishes a wireless access communication session, the terminal needs to send the session information to the proximity service function, and the proximity service function nodes exchange session information, and then the proximity service function node searches through the network. The session management function node corresponding to the session associates the session information of the second terminal with the session information of the first terminal and sends it to the first session management function node through a new interface, and then the first session management function node can search through the obtained information To the session management function information of the second terminal, the session management function node connects the two sessions of the terminal based on the session information by controlling the user forwarding function, and finally notifies the terminal of the successful connection of the session, so as to realize the short-distance communication between terminals. The goal of ensuring business continuity after business communication is converted to wireless access network communication.

When the terminals switch from short-distance business communication to establishing a communication session through the wireless access network, since the terminals do not exchange their own session information after establishing the session, it is necessary to connect the session through the network (eg: session management function) to ensure service continuity.

After establishing a new session, the terminal needs to send the session information to the ProSe function.

After receiving the session information, the ProSe function needs to exchange its own session information (eg: PDU session ID, DNN). If the terminal is connected to the same ProSe function at this time, there is no need to exchange session information.

The ProSe function searches the network for the session management function corresponding to the session.

An interface needs to be added between the proximity service function and the session management function.

The first ProSe function needs to associate the session information of the second terminal with the session information of the first terminal, and send it to the first session management function through the new interface.

The first session management function finds the second session management function corresponding to the session of the second terminal through the network, and if the terminal is connected to the same session management function at this time, no search is required.

The session management function connects two sessions of the terminal based on the session information by controlling the user forwarding function.

The session management function notifies the terminal that session data can be transmitted.

For ease of understanding, terminal A corresponds to the proximity service function node A, terminal B corresponds to the proximity service function node B, terminal A corresponds to the session management function node A, terminal B corresponds to the session management function node B, and terminal A corresponds to the user forwarding function node A , the terminal B corresponds to the user forwarding function node B, to describe the specific process of the embodiment of the present disclosure.

As shown in Figure 3, first, an interface between the ProSe function and the session management function is added.

1. Terminals A and B complete their respective proximity service authorizations; and terminals A and B complete proximity service discovery and establish Prose direct communication; the terminal Identity obtained by mutual authorization between proximity service functions

At this time, due to the poor communication quality between the terminals (for example: the communication range exceeds the reachable range), the terminals can no longer communicate through the short-distance service

2a, 2b: Each terminal establishes a new session, and the session management function registers the session information to the data management

3a, 3b: The terminal sends the session information to the proximity service function

4. After the proximity service function receives the session information, it exchanges its own session information (eg: PDU session ID, DNN). If the terminal is connected to the same proximity service function at this time, there is no need to exchange session information, which has been implemented in step 3.

5, 6: The proximity service function searches the session management function corresponding to the session through the network, associates the session information of terminal B with the session information of terminal A, and sends it to the session management function_A through the new interface

7. The session management function _A searches for the session management function _B corresponding to the session of the terminal B. If the terminal is connected to the same session management function at this time, there is no need to search.

8. Session management function _A and session management function _B connect the sessions established in steps 2a and 2b based on the session information by controlling the user forwarding function

9a, 9b: The session management function notifies the terminal that session data can be transmitted (eg: through a new interface or through AMF, AN)

10. The terminal switches the session to the session connected in step 8

So far, data transmission is performed between the terminals through the wireless access network.
