X2-interface-based load balance method and device for shunting users and loaning resources

Abstract

The invention discloses an X2-interface-based load balance method and device for shunting users and loaning resources, and relates to a mobile communication system. The method comprises the following steps: carrying out measurement information interaction between home base stations and macro base stations as well as between home base stations through a direct X2' interface and a direct X2 interface; analyzing the load state and the condition of resources near an overload base station according to the measurement information; switching the users or loaning resource blocks according to information analyzing results; marking the user as a home base station primary UE or UE switched from an adjacent base station by coordinating after the user service is configured; withdrawing the resources according to marks by the base stations after the UE ends servicing. According to the method and the device, the direct X2 interface is used for coordinating the base stations; the balance convergence rate of the load is increased; the network cost is reduced; the load is shunted by switching the UE or loaning the resource blocks, so that the service quality of the users is improved; the wireless resource can be relatively efficiently used; the Ping-Pang switch is effectively avoided.

Description

technical field [0001] The present invention relates to a mobile communication system, and in particular, to user offloading and resource secondment based on direct X2 interface between home base stations, between home base stations and macro base stations in a long term evolution mobile communication system (LTE / LTE-Advanced, Long Term Evolution). Load balancing method and device. Background technique [0002] With the rapid development of wireless communication technology, the popularization of wireless broadband access and the improvement of data transmission requirements, people have put forward higher requirements for the speed and quality of mobile communication. In the currently operating network, business objectives, system structure, operating environment and user requirements are constantly changing, so the network is required to dynamically adapt to these changes to ensure better service for users. [0003] With the deepening of the complexity of mobile network o...

Problems solved by technology

[0005] Prior to this, the communication and negotiation of information between macro base stations needs to be carried out through the S1 interface (S1 is the communication interface between the base station and the packet core network (EPC) defined in the third-generation mobile communication technology specification organization 3GPP), so that information The transmission needs to be forwarded through the evolved packet core network (EPC), so the efficiency of information transmission is low and the delay is large, so that the macro base stations cannot negotiate in a timely manner and make corresponding decisions

In LTE, due to the addition of femtocells, previous methods can no longer meet complex network conditions
