Problems solved by technology

[0005] When a macro cell needs to perform MLB, if no suitable adjacent macro cell can be found, MLB will not be completed, resulting in a decrease in system capacity, failing to achieve the effect of network-wide optimized load balancing, and even leading to unstable or unstable system operation. QoS (Quality of Service, service quality) decline

Embodiment Construction

[0059] Since the existing MLB scheme is limited to the scenario of balancing the load of an overloaded macro base station to another macro base station, it does not consider how to complete MLB when the overloaded macro base station cannot find an adjacent macro base station, which may easily lead to Can't finish MLB.

[0060]In order to solve the above defects, in the technical solution provided by the present invention, when the overloaded macro base station cannot find an adjacent macro base station to perform MLB, it can search for a suitable public home base station, and implement MLB with the public home base station, so as to improve the network efficiency. capacity and user quality of service.

[0061] by figure 1 The scenario shown is an example, the macro base station eNB cell Provide services to UEs within its coverage, and the eNB cell with two home base stations HeNB1 cell and HeNB2 cell have a common coverage area. When eNB cell When overloaded, if the eNB...

Abstract

The invention discloses a mobility load balance realizing method and a device. The method comprises the following steps that: when a macro base station is required to execute the mobility load balance, the macro base station selects a target public home base station according to information of public home base station reported by user equipment; and the macro base station switches the user equipment served by the macro base station to the target public home base station in the coverage of the target public home base station. Through the above technical scheme, the mobility load balance success rate can be improved, and the network-wide optimized load balance can be realized.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for implementing mobile load balancing. Background technique [0002] With the development of the communication network, the MLB (Mobility Load Balance, mobile load balancing) characteristic of the network becomes more and more important. When the load of the cell is higher than a certain threshold, it can negotiate with the surrounding cells, and by modifying the mobility parameters, the UE (User Equipment, user equipment) in the cell with high load is handed over to the cell with low load, so as to achieve the load Balanced, providing more accessible resources for the source cell, reducing the access rejection rate, and improving system capacity. [0003] In the existing MLB scenario, it is usually limited between two directly adjacent macro cells. When the load of a macro cell is higher than the preset threshold, it can negotiate with its ad...
