Abstract

Provided are a communication resource management method, a user equipment (UE), a base station and a system, the method comprising: a first UE sends a discovery message to at least one second UE in a wireless network, the discovery message carrying a group identifier of a D2D (device to device) (D2D) communication group and a service identifier corresponding to the D2D communication group; the first UE receives a first application message sent by the second UE, the first application message carrying a user identifier of the second UE; according to the first application message sent by the second UE, the first UE obtains a communication resource for the D2D communication group to perform communication; according to the user identifier of the second UE, the first UE sends the communication resource to the second UE in the D2D communication group, in order to notify each UE in the D2D communication group to perform D2D communication service corresponding to the service identifier using the communication resource. The present invention provides a technical solution enabling the D2D communication to proceed smoothly and reducing or avoiding interference toof cellular network communication.

Description

technical field [0001] The present invention relates to communication technology, in particular to a communication resource management method, user equipment, base station and system. Background technique [0002] At present, mobile communication networks are developing toward higher transmission rates, resource utilization and network capacity, which puts forward higher requirements for future wireless spectrum resources. Device-to-device (D2D) communication refers to direct communication between devices that do not pass through transit devices (such as base stations or access points, etc.) on the data plane in wireless communication, thereby reducing the load on cell base stations. [0003] In the prior art, resources used by D2D communication are the same as resources used by cellular network communication. In order to avoid interference of D2D communication on cellular communication, cellular network nodes such as base stations are required to be responsible for coordina...
