Abstract

Disclosed are a communication switching and establishing method and device. A switching procedure comprises: an access network device determining to switch from a D2N link to a D2D link; sending a switching command to a first terminal and a second terminal; receiving a switching complete response; and saving bearer information of a bearer, which needs to be switched to the D2D link, in the D2N link, or requesting to send a bearer keep request to a core network node. A communication establishing procedure comprises: after the access network device determines that communication needs to be established with the D2D link, determining whether a core network side link needs to be established for communication between the first terminal and the second terminal; if yes, sending a service request to a core network device, so that the core network device establishes a core network side link for the service request; and sending configuration information of the D2D link and establishment instruction information of the D2D link to the first terminal and/or the second terminal. The present application enables a first terminal and a second terminal to perform D2D communication, thereby enhancing network transmission efficiency.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for switching and establishing communications. Background technique [0002] In the existing communication system, the mode of network centralized control is adopted, that is, the uplink and downlink data of user equipment (User Equipment, UE, also called terminal) are all transmitted under the control of the network side. The communication between two UEs needs to be forwarded and controlled by the core network. [0003] During the development of the communication system, in order to better meet user needs and improve the efficiency of information exchange, a mechanism for mutual discovery and even direct communication between UEs is introduced, that is, Device to Device (D2D) communication. [0004] When two UEs are close to each other, if the D2D communication requirements are met, the two UEs can perform D2D communication. There are two si...
