A load sharing method and device

Abstract

An embodiment of the invention provides a load sharing method and device, relates to the field of communication, and aims to reduce information transmission between a macro cell and a micro cell and lower the requirement on inter-communication capacity of micro cells at the premise of not affecting the macro cell to micro cell load-sharing process. The method includes the steps: after the macro cell receives a service request sent by a user device, the macro cell acquires a first message which is sent by the micro cell and which includes a first identifier used for indicating whether or not the micro cell is allowed to gain access to the user device; if yes, the macro cell judges whether or not the user device is allowed to share load to the micro cell; if yes and when the user device is in coverage of the micro cell, the macro cell shares the load of the macro cell to the micro cell. The load sharing method and device according to the embodiment is applicable to load sharing of macro and micro cells.

Description

technical field [0001] The present invention relates to the communication field, in particular to a load sharing method and device. Background technique [0002] With the development of communication technology, the networking mode of the cell network usually adopts a mixed networking mode of one macro cell and multiple micro cells, so that the micro cell can share part of the business of the macro cell and meet the service requirements of user equipment. [0003] At present, in the prior art, when the user equipment enters the mixed macro and micro cell networking scenario, the user equipment will reside in the macro cell in the area without micro cell coverage; once it enters the macro cell and micro cell coverage According to the signal quality and network load of the micro cell sent by the micro cell, the macro cell will judge whether the user equipment needs to share the load to the micro cell for service. For example, when the signal quality of the micro cell is bette...

[0004] However, in the prior art, when the macro cell judges whether the user equipment needs to load share to the micro cell for service according to the signal quality and network load of the micro cell, the micro cell needs to send its current signal quality information and load information to the macro cell, Since the definition of messages about load sharing between macro cells and micro cells is not a unified standard definition, in the actual implementation of load sharing, different equipment vendors may have different definitions of messages, so that when When provided by the equipment manufacturer, it is necessary to have better intercommunication capabilities between the macro cell and the micro cell to prevent errors in message transmission between the macro cell and the micro cell.
