Method and device for signaling load balancing between RNCs

Abstract

The invention provides a method and a device for balancing signaling load between RNCs. The method comprises: determining the load transfer-out RNC according to the signaling load of each RNC in a pre-built RNC cluster in a certain area, and determining the load transfer-in RNC according to the edge weights of the RNCs connected to the load transfer-out RNC; The pre-built load transfers the linear relationship model between the signaling load and the number of RRC connection establishment requests from the RNC, and the pre-built load transfers into the RNC. The calculation of the linear relationship model between the signaling load and the number of RRC connection establishment requests meets the load balancing principle The amount of load transferred out and the amount of load transferred in; according to the amount of load transferred out and the signaling load of the RNC caused by each base station under the load transferred out by the RNC, determine the M base stations that need to be transferred into the RNC; A base station is moved into the load transfer-in RNC to realize load balancing among RNCs in the RNC cluster.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and device for balancing signaling load between RNCs. Background technique [0002] In recent years, the rapid growth of mobile Internet services has become an important revenue growth point for mobile operators. At the same time, the soaring volume of mobile Internet services such as WeChat and mobile QQ has brought huge challenges to mobile network construction, operation and maintenance for mobile operators. With the full rollout of 4G network construction, under the pressure of huge network construction costs, various mobile operators have reduced or even stopped investment in 3G networks. However, the Internet service volume of 3G networks, especially the RNC signaling load, is still increasing due to the popularization of various mobile smart terminals, and it is particularly prominent in some hot spots. How to make effective ...
