System and method of realizing C-RAN load balance on the basis of household base stations

Abstract

The invention discloses a system and method of realizing C-RAN load balance on the basis of household base stations. The load balance system comprises a load detection module, an information processing module, a switching decision module and a switching execution module. The switching decision module confirms a wireless access network switching order set according to overload neighborhood information list provided by the load detection module and a usable household base station information list provided by the information processing module. The switching execution module executes switching according to the wireless access network order set provided by the switching decision module so as to enable mobile users in an overload neighborhood to be switched to an adjacent household base station. Consequently, load balance of the C-RAN wireless access network is realized, and meanwhile network sources of leisure household base stations are utilized reasonably.

Description

technical field [0001] The invention belongs to the field of wireless communication, and more specifically relates to a system and method for realizing C-RAN load balancing. Background technique [0002] In the wireless communication cellular network system, the number of access users and the amount of business data that each cell needs to carry are random and unevenly distributed, especially problems such as traffic bursts and network congestion caused by hotspot cells, making The load in the whole system is in an unbalanced state, therefore, realizing load balancing of each cell has become one of the urgent problems to be solved in the mobile communication system. The traditional load balancing method is to balance the load status among cells by switching users or cell reselection. The Long Term Evolution (LTE) system is a new generation of mobile communication technology standard. The specific load balancing process is as follows: the network detects the load situation t...

At the same time, the wireless access network of the C-RAN architecture and the home base station network are connected to each other through the Internet, and the baseband resource pool in the C-RAN wireless access network interacts with the home base station control center in the home base station network. The home base station can assist the C-RAN The architecture realizes network load balancing, but there is a lack of a method to achieve C-RAN load balancing based on home base stations, and the traditional load balancing method based on distributed systems cannot be applied to realize centralized C-RAN architecture wireless access based on home base stations Network load balancing
