User selection switching method based on moving load balancing mechanism

Abstract

The invention discloses a user selection switching method based on a moving load balancing mechanism, mainly solving the problems of interrupted communication or Ping-Pong switching caused by rapidly descensive signal quality easily appearing in the prior method under the circumstance that a user moves at high speed. The user selection switching method has the specific process that a source base station detects the load condition of a cell and decides whether the load balancing mechanism is started or not; the source base station and an adjacent base station exchange load information by an X2 interface and determine an objective cell to which the load is transferred according to the obtained load information of the cell and an adjacent cell; the source base station and an objective base station consult to update respective switching parameter; the source base station makes the reselection on users satisfying switching toggle conditions after the switching parameters are altered so as to determine non real-time service users moving in the manner of deviating from the direction of the base station as final users to be switched; and the users to be switched are switched to the objective cell so as to realize the intra-cell load balancing. The invention greatly increases the probability of normal conversation after the switching is finished, ensures the continuity of user service and improves the user service quality and the system performance and is used for the moving load balancing mechanism of the next-generation mobile communication system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and to the evolved global continental wireless access network, in particular to a method for selecting a suitable user for handover under a mobile load balancing mechanism, which is used to balance the service load between cells in mobile load balancing Reasonable distribution. Background technique [0002] Mobile load balancing is to distribute the business load between cells reasonably. The purpose of reasonable distribution is to ensure efficient utilization of wireless resources, increase system capacity, maintain high QoS of sessions as much as possible, and ensure a sufficiently small call drop rate. A general mobile load balancing algorithm requires cell handover or cell reselection. The purpose of doing so is to switch the services of a heavily loaded cell to a lightly loaded cell. [0003] The long-term evolution technology achieves the purpose of mobile load balanc...

Problems solved by technology

In step (5) of the above process, among the users who meet the handover trigger conditions, there are some users who move to the source cell with heavy load at high speed. As a result, communication interruption or ping-pong switching will affect the user's service continuity, service quality and system performance.
