Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] Device to Device (D2D) communication technology can realize service and data application of local ad hoc network (ad-hoc) network and short-distance communication. To improve spectrum utilization, the D2D system shares the same resources as the cellular system. When a D2D terminal in a D2D system accesses a cellular system, it must follow ...

Abstract

The invention provides a communication switching method, user equipment and a base station. The communication switching-over method comprises the following steps: the user equipment (UE) receives a time-frequency resource produced when D2D communication is carried out between the UE and another UE, the time-frequency resource can indicate a D2D work cycle of the D2D communication, the D2D communication is carried out between the UE and another UE during the D2D work cycle according to the time-frequency resource, the D2D communication between the UE and another UE is stopped temporarily when the D2D work cycle is ended, the UE is communicated with the base station when the UE enters a working cycle during which the UE is communicated with the base station, and the work cycle during which the UE is communication with the base station and a work cycle during which another UE is communicated with the base station are synchronous. According to the communication switching-over method, the user equipment and the base station, a method for switching-over between the D2D communication and traditional communication is provided, the traditional communication between the two UEs and the base station can be carried out normally in the D2D communication process.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a communication handover method, user equipment, and a base station. Background technique [0002] In a traditional cellular network, when a user equipment (User Equipment; UE) wants to communicate with other UEs, it needs to pass through a base station (such as an evolved base station (evolve NodeB; eNB)), even if the two UEs are very close to each other , but also through the eNB. The advantage of being controlled by the eNB is that the eNB can centrally control the use of radio resources of the cell, which is beneficial to interference control; however, this traditional communication method will cause a large network load. [0003] For example, to transmit the same amount of data, when two UEs with close distances can communicate directly, compared with the communication mode of cellular mode, wireless resources can be used more effectively...
