A Load Balancing Method and Device Based on Periodic Measurement Report

Abstract

The embodiment of the present invention discloses a load balancing method and device based on periodic measurement reports. The method includes: the base station receives the periodic MR data reported by the terminal, and records the level value of the local cell in the periodic MR data; if the load of the local cell is greater than Threshold, the target user to be balanced this time is determined according to the load situation of the adjacent area with the same coverage; the target user is screened according to the load balancing user selection strategy configured by the base station and the periodic MR data, a candidate list of balanced users is generated, and the candidate list is sequentially selected The users in the list perform load balancing; the periodic MR data is obtained by the terminal according to the period and measurement frequency configured in the periodic MR measurement and control message. Through the base station recording periodic measurement report data, the central user can be selected more effectively to achieve the effect of load balancing, reduce the situation of high load in adjacent cells due to balancing, and reduce the number of times users in the network repeatedly perform balancing between cells, improving user efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a load balancing method and device based on periodic measurement reports. Background technique [0002] With the explosive growth of mobile Internet applications, users have turned from accepting to relying on services such as mobile Internet access, video on demand, sending and receiving emails, and downloading. Mobile operators must provide greater bandwidth and capacity to meet user needs. With the gradual increase of 4G network users, single-carrier and dual-carrier in hotspot areas will not be able to meet the needs of users for large bandwidth and high capacity. However, from the perspective of actual network load, in many scenarios, users are concentrated in one or two cells in the station, while there are fewer users in other cells in the same coverage station. At the same time, the number of users in some base stations with the same c...

Problems solved by technology

When the A2 configuration value is -80dB, the A2 threshold is easy to meet, and there will be more users reporting A2 measurement reports in the cell, and it is not easy to select the central user. At this time, it is necessary to select among the users reporting A2 measurement reports. In this case , the RSRP (Reference Signal Receiving Power, reference signal receiving power, that is, the level value) of the users reporting the A2 measurement report is between -80dB and -110dB. For the base station, these users are randomly selected, and it is likely to choose - 100dB users are configured with load-balanced A4, but these users are already at the edge of the cell and it is difficult to report A4 measurement reports normally, resulting in the inability to balance users and complete load balancing between cells, making the long-term high-load state of the cell affect the use of users
