一种负载均衡方法、网络设备及系统A load balancing method, network equipment and system

技术领域technical field

本发明涉及通信领域的管理技术，尤其涉及一种负载均衡方法、网络设备及系统。The invention relates to management technology in the communication field, in particular to a load balancing method, network equipment and system.

背景技术Background technique

随着无线通信网络的不断发展，在时分同步码分多址(TimeDivision-SynchronousCodeDivisionMultipleAccess，TD-SCDMA)、全球移动通信系统(GlobalSystemforMobileCommunication，GSM)网络中，当出现负载不均衡情况时，需要网络维护人员在OMC侧通过监控发现问题，并人为的施以临时参数调整。在长期演进(LongTermEvolution，LTE)网络中为提高优化效率，提出了负载均衡(MobilityLoadBalancing，MLB)功能用以解决这种负载不平衡现象；主要用于小区负荷过高，或者发生多小区间的业务负荷分布不均衡的场景，其目标是通过某种方式改变业务负荷分布，使无线资源保持较高的利用效率，同时保证已建立的业务的服务质量(QualityofService，QoS)。With the continuous development of wireless communication networks, in Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) and Global System for Mobile Communication (GSM) networks, when load imbalance occurs, network maintenance personnel are required On the OMC side, problems are found through monitoring, and temporary parameter adjustments are made artificially. In order to improve the optimization efficiency in the Long Term Evolution (LTE) network, the load balancing (Mobility Load Balancing, MLB) function is proposed to solve this load imbalance phenomenon; it is mainly used for the excessive load of the cell, or the business between multiple cells In the scenario of unbalanced load distribution, the goal is to change the service load distribution in a certain way, so as to maintain a high utilization efficiency of wireless resources, and at the same time ensure the quality of service (Quality of Service, QoS) of the established service.

但是，不同厂商设备之间无法实现负载均衡，对于不同网络的服务商的设备，需要分别的由OMC根据基站上报的测量数据进行分析，因而难以形成统一的优化决策，从而难以实现跨厂商的负载均衡优化，如此就会出现上述几种不同制式的网络之间无法进行负载均衡，因此让新网络有效的分担原网络的话务量，出现“旧网忙死，新网闲死”的情况。However, load balancing cannot be achieved between devices from different manufacturers. For the devices of different network service providers, the OMC needs to analyze the measurement data reported by the base station separately. Therefore, it is difficult to form a unified optimization decision, and it is difficult to achieve cross-vendor load. Balance optimization, so that load balancing cannot be performed between the above-mentioned networks of different standards, so the new network can effectively share the traffic of the original network, and the situation of "the old network is busy and the new network is idle" appears.
