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 invention aims to provide a method and equipment for controlling terminal communication. The method comprises the following steps: introducing a D2D (Device-to-Device) configuration file into an HSS (Home Subscriber Server); when a terminal is attached to a network, judging whether the terminal has a D2D capability or not and preferably selecting a D2D Relay manner by a server; if so, when the server detects that the distance between the terminal and one piece of D2D Relay equipment is within the range of D2D communication, triggering the terminal to access the network through the D2D Relay equipment; and after a communication connection is established between two terminals through the network, if the server finds that the two terminals satisfy a D2D communication triggering condition, triggering establishment of a D2D communication connection between the two terminals. Through adoption of the method and the equipment, the low efficiency of manual switching is avoided; the advantages of D2D communication can be utilized fully; the load of a core network is relieved; and the communication processing capability is improved under the condition of constant capacity and performance of the core network.

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...
