Embodiment Construction

[0035] The present invention introduces a D2D configuration file, which is used to describe the data related to D2D communication of the terminal, which may contain one or more of the following information but is not limited thereto:

[0036] -Whether the terminal has D2D capability;

[0037] It means that the terminal supports D2D communication or does not support D2D communication.

[0038] - D2D technology supported by the terminal;

[0039] It refers to the D2D communication technology supported by the terminal if it supports D2D communication, which may be, for example, LTE, WiFi, etc. There may be one or more D2D communication technologies supported by a terminal.

[0040] - D2D communication objects allowed by the terminal;

[0041] It refers to which objects the terminal allows to establish D2D communication with it. The communication objects here can be ordinary D2D terminals or D2D Relay devices, and D2D Relay devices include GW (GateWay, gateway) and terminals. ...

Abstract

The object of the present invention is to provide a method and device for controlling terminal communication. This invention introduces D2D configuration files into HSS. When the terminal is attached to the network, the server determines whether the terminal has D2D capabilities and selects the D2D Relay method. If so, when the server detects that the distance between the terminal and a D2D Relay device is within the range of D2D communication, it will trigger the terminal to access the network through the D2D Relay device. When two terminals establish a communication connection through the network, if the server finds that they meet the conditions for triggering D2D communication, it will trigger the establishment of a D2D communication connection between the two terminals. By adopting the present invention, not only the inefficiency of manual switching is avoided, but also the advantages of D2D communication can be fully utilized, the load of the core network can be reduced, and the communication processing capability can be improved while the capacity and performance of the core network remain unchanged.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a D2D communication technology. Background technique [0002] As a key candidate technology for 5G, D2D communication (Device-to-Device, device-to-device) has the potential to improve system performance, enhance user experience, and expand cellular communication applications, and has attracted widespread attention. D2D communication based on the cellular network, or Proximity Service (Proximity Service, ProSe), means that user data can be directly transmitted between terminals without going through the network. [0003] In many scenarios, the UE can communicate through D2D communication or through the network. However, traditional wireless communication networks have high requirements for communication infrastructure, and damage to core network facilities or access network equipment may lead to the breakdown of the communication system. The introduction of D2D...
