Resource selection method and base station

Abstract

A resource selection method, comprising: receiving first Discovery broadcast information sent by a base station, the first Discovery broadcast information including: first energy level information of a second user equipment, and determining the distance of the first user equipment A level area, the distance level area is an area divided based on the unit distance between the base station and the user equipment; listening to the second user equipment, and acquiring second energy level information of the second user equipment, the second energy The level information is used to indicate the distance level between the second user equipment and the first user equipment; according to the first energy level information, the distance level between the second energy level information and the first user equipment The area selects unoccupied PDRB resources, so that user equipments in the same area group select PDRB resources of the same frequency band.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource selection method and a base station. Background technique [0002] With the wide application of social applications, the short-distance discovery function becomes more and more important. For example, the user hopes to be able to know in time that a friend appears or leaves around. The function of close discovery will make people's life and work more convenient. For example, when a user arrives at the office, through the proximity discovery function, he can immediately know which colleagues have also arrived at the office. [0003] In the SAE communication system, the network architecture is shown in the figure. The terminal accesses the mobile management entity (MME-Mobile Management Entity) / serving gateway (S-GW: Serving Gateway) of the core network through the evolved base station (eNodeB), and connects to the packet data network gateway (P-GW) through the S-GW ...

AI Technical Summary

Problems solved by technology

[0007] The user's resource application adopts the random access channel (RACH, Random Access Channel) method, which needs to interact with the base station side 4-5 times, resulting in a large base station overhead, and paying more system overhead for the user's resource application; and, the base station The discovery (Discovery) information of the user equipment is not listened to, it is difficult to solve the problem of resource reuse, and it is impossible to realize the centralized control of the resource allocation of the user equipment by the base station
