随着4G用户的逐渐增长,热点区域部署了双多载波。当某个小区的负荷达到一定程度,其接入、吞吐率等指标则会发生恶化。负载均衡功能能够一定程度上解决该问题,该功能根据服务小区和其邻区负荷状态以及覆盖上的具体情况,通过切换和重选驱使合适的用户去其它相对空闲的小区继续进行业务。这样既可以有效地使用系统资源,又可以提高系统的容量和稳定性。 As 4G subscribers grow, dual-carrier is deployed in hot spots. When a certain district’s load reaches a certain level, its access, throughput and other indicators will deteriorate. The load balancing function can solve this problem to some extent. This function drives the appropriate users to go to other relatively free cells by switching and reselecting according to the load status of the serving cell and its neighboring cells and coverage. This can not only effectively use the system resources, but also can improve the system capacity and stability.
