Load balance method and device

Abstract

The embodiment of the invention provides a load balance method and device. The method comprises the steps of: if a high-load state notification message from a service cell is received, modifying a default value corresponding to a personalized migration parameter OCN of a target cell itself, wherein the target cell and the service cell are adjacent cells, and the high-load state notification message is sent by the service cell to the target cell when the service cell detects that the service cell itself is in a high-load state; and configuring the modified OCN to a new access user and / or a switch-in user, wherein the switch-in user is a user being balanced from the service cell to the target cell. The load balance method and device effectively improve the load balance effect, the user perception and the network service quality.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a load balancing method and device. Background technique [0002] In the current mobile communication network, TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution) network is developing rapidly. In order to meet the rapidly growing number of customers and the gradually enhanced service quality requirements, operators have adopted two-layer or even multi-layer network Deployment strategy for simultaneous coverage. For example: China Mobile's F-band and D-band double-layer coverage network, due to the difference in propagation characteristics, F-band has the advantage of wider coverage than D-band, but F-band has fewer frequency resources than D-band. The D-band has an advantage in frequency resources, which can achieve the goal of ensuring coverage through the F-band in the fringe area, and sharing the load and absorbing capacity t...

Problems solved by technology

[0006] 1) Using the suppression strategy in the prior art embodiment, if there are new access users in the low-load cell, the new access user may quickly switch to the high-load cell after accessing, resulting in that the load of the high-load cell cannot be timely and effectively Reduced, poor load balancing effect, affecting customer perception and network service quality

[0007] 2) The existing solution only considers the suppression strategy of neighboring cells with the same coverage, which may cause UEs under non-same coverage neighboring cells (neighboring cells under a single-layer network) to continuously switch to high-load neighboring cells, which also affects the load balancing effect and reduces User Perception and Network Quality of Service

[0008] 3) The above two problems lead to an increase in the number of switching, and there is a risk for KPI (Key Performance Indicator, key performance indicator) indicators

[0009] For the above technical problems, no effective solution has been proposed yet
