As described in the background section, current mobile networks need a path switching method for supporting switching from near-field communication to network communication between terminals. In the related art, when the near field communication between terminals is converted to network communication, service continuity cannot be ensured.
The inventors found that the path switching method for the proximity service in the related art, which switches from the proximity service communication to the radio access network communication between terminals, has not been supported, and that there is no interface between the proximity service function and the session management function.
Based on the above-mentioned problems, the embodiments of the present disclosure provide a method for converting near-field communication into network communication, adding an interface between a proximity service function and a session management function, transmitting session information and session management function information of a terminal through a network, and connecting two sessions of the terminal by controlling a user forwarding function, thereby achieving the goal of ensuring service continuity after converting the near-field service communication into wireless access network communication between the terminals.
Near field communications in embodiments of the present disclosure may also be referred To as near field communications traffic, and may include D2D (Device To Device) communications. For ease of understanding, the following description is exemplary with D2D communication in near field communication.
The method for converting near-field communication into network communication provided in the present disclosure may be applied to a 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, in-vehicle devices, wearable devices, computing devices, internet of things devices or other processing devices connected to a wireless modem, as well as various forms of user equipment, mobile Stations (MSs), terminals (terminal devices), etc. having wireless communication capabilities. For convenience of description, the above-mentioned devices are collectively referred to as a terminal.
The network device 104 may be a base station, which may be a device deployed in an access network to provide wireless communication functionality for terminals. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like.
In systems employing different radio access technologies, the names of base station capable devices may vary, for example in LTE systems, called enodebs or enbs; in a 5G NR-U system, it is called gNodeB or gNB.
In some scenarios, a "base station" may also be referred to as a "cell".
As communication technology evolves, the description of "base station" may change. For convenience in the embodiments of the present disclosure, the above-mentioned devices for providing 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 some air interface technology, such as Uu interface.
In some embodiments, the first terminal 102 and the second terminal 106 communicate with each other via some communication technology.
Alternatively, communication between the first terminal 102 and the second terminal 106 may be via bluetooth or WiFi technology.
Alternatively, the first terminal 102 and the second terminal 106 support Device-to-Device (D2D) communication, and side link (sidelink) communication between the first terminal 102 and the second terminal 106 may be performed through a PC-5 interface.
Wherein the side-link communication is addressed by the source and destination identities of the MAC layer, i.e. no connection need be established before the communication.
When there is a service between the first terminal 102 and the second terminal 106 in the cellular system that needs to be transmitted, the service data from the first terminal 102 to the second terminal 106 is first transmitted to a Base Station (or eNB or evolution) of the cell where the first terminal 102 is located through an air interface, the Base Station transmits the user data to a Base Station of the cell where the second terminal 106 is located through a core network, and the Base Station transmits the service data to the second terminal 106 through an air interface. The traffic data transmission from the second terminal 106 to the first terminal 102 uses a similar process flow.
When the first terminal 102 and the second terminal 106 are located in the same cell, two radio spectrum resources are consumed by one data transmission, although both terminals are covered by the same cell of the base station.
If the first terminal 102 and the second terminal 106 are located in the same cell and are closely spaced apart, the above-described cellular communication method is clearly not an optimal way of communication.
Also, with diversification of mobile communication services, for example, social networks, electronic payments, etc. are increasingly applied in wireless communication systems, so that the service transmission demands between close-range users are increasing.
Based on the above requirements, in a traffic transmission scenario between close-range users, a D2D communication mode is becoming more common. For example, the D2D communication scheme may be employed between the first terminal 102 and the second terminal 106 hereinabove.
In the D2D communication scheme, service data is directly transmitted to the target ue through the air interface by the source ue without being forwarded by the base station, which may also be referred to as proximity services (Proximity Service, proSe for short).
This communication mode is distinguished from the communication mode of a conventional cellular system. For users in close range communication, D2D not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network.
The D2D communication based on the cellular network is a technology for directly carrying out communication among a plurality of terminal devices supporting the D2D function under the control of the system, and can reduce the occupation of system resources, increase the frequency spectrum efficiency of the cellular communication system, reduce the transmitting power consumption of the terminal and save the network operation cost to a great extent.
With continued reference to fig. 1, when the location 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 large, the effect of D2D communication becomes poor, and direct communication between the first terminal 102 and the second terminal 106 may not be possible through the short-range service, so that a transition to network communication is required therebetween. The method for converting near field communication into network communication provided by the embodiment of the disclosure can be applied to the conversion process.
Fig. 2 is a flowchart of a method for converting near-field communication to network communication in an embodiment of the disclosure, and as shown in fig. 2, the method for converting near-field communication to network communication provided in the embodiment of the disclosure includes the following steps:
step S202, when a first terminal and a second terminal need to switch from near field communication to network communication, a first adjacent service function node associates session information of the second terminal to session information of the first terminal;
Step S204, the first adjacent 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 to enable the user forwarding function node to connect the session of the first terminal with the session of the second terminal based on the session information;
step S208, the session management function node informs the first terminal to switch to network communication;
in step S210, the session management function node notifies the second terminal to switch to network communication.
It should be noted that, the embodiments of the present disclosure require that a communication interface be provided between the proximity service function node and the session management function node.
When the terminals are converted from near-field service communication to the wireless access communication session establishment of the terminals, the terminals need to send session information to the adjacent service functions, the adjacent service function nodes interact session information, then the adjacent service function nodes search the session management function nodes corresponding to the session through a network, the session information of the second terminal is related to the session information of the first terminal and sent to the first session management function nodes through a new interface, the first session management function nodes can search the session management function information of the second terminal through the obtained information, the session management function nodes control the user forwarding function to connect two sessions of the terminals based on the session information, and finally inform the terminals of successful session connection information, so that the aim of ensuring service continuity after the conversion from near-field service communication to wireless access network communication between the terminals is achieved.
When the communication session is established from the short-range service communication to the wireless access network, the terminals do not interact with the session information after each session is established, so that the session needs to be connected through the network (eg: session management function) to ensure the service continuity.
The terminal needs to send session information to the proximity service function after a new session is established.
After receiving the session information, the proximity service function needs to interact with the session information (eg: PDU session ID, DNN), and if the terminal is connected with the same proximity service function, the session information does not need to be interacted.
The proximity service function searches for a session management function corresponding to the session through the network.
An interface needs to be added between the proximity service function and the session management function.
The first proximity service function needs to associate session information of the second terminal with session information of the first terminal and send it to the first session management function through the new interface.
The first session management function searches the second session management function corresponding to the second terminal session through the network, and if the terminal is connected with the same session management function at the moment, the search is not needed.
The session management function connects two sessions of the terminal based on session information by controlling the user forwarding function.
The session management function informs the terminal that session data can be transmitted.
For ease of understanding, specific processes of embodiments of the present disclosure are described below with terminal a corresponding to a proximity service function node a, terminal B corresponding to a proximity service function node B, terminal a corresponding to a session management function node a, terminal B corresponding to a session management function node B, terminal a corresponding to a user forwarding function node a, and terminal B corresponding to a user forwarding function node B.
As shown in fig. 3, first, an interface between a proximity service function and a session management function is added.
1. Terminals A and B respectively complete respective adjacent service authorization; and the terminals A B complete the proximity service discovery and establish Prose direct communication therebetween; terminal Identity obtained by interaction authorization between adjacent service functions
At this time, due to poor communication quality (for example, the communication range exceeds the reachable range), communication between terminals cannot be performed through the short-distance service
2a, 2b: the terminals each establish a new session in which session management functions register session information to data management
3a, 3b: the terminal sends the session information to the proximity service function
4. After receiving the session information, the proximity service function interacts with the session information (eg: PDU session ID, DNN) respectively, and if the terminal is connected to the same proximity service function at this time, the session information does not need to be interacted, which is already implemented in step 3.
5. 6: the proximity service function searches the session management function corresponding to the session through the network, correlates the session information of the terminal B to the session information of the terminal A, and sends the session information to the session management function_A through a new interface
7. The session management function_a searches the session management function_b corresponding to the session of the terminal B, and if the terminal is connected with the same session management function at this time, the search is not needed.
8. Session management function_a and session management function_b connect sessions established in steps 2a,2B based on session information by controlling a user forwarding function
9a, 9b the session management function informs the terminal that session data can be transferred (eg: through a new interface or through AN AMF, AN)
10. The terminal switches the session to the session connected in the step 8
The terminals perform data transmission through the wireless access network.
