Problems solved by technology

[0017] It can be seen that there is no means to avoid the occurrence of ping-pong handover in the handover process initiated by the above mobile terminal
Moreover, once the ping-pong handover occurs, not only will it directly affect the normal operation of the mobile terminal, but at the same time, the handover process will also occupy a large amount of communication resources in the wireless communication system, thereby affecting the system communication performance.

Embodiment Construction

[0049] The core of the present invention is that when a mobile terminal needs to perform a handover operation, at first, according to the service performance parameter information of the cell, it is determined that the corresponding target cell can be reliably used as the serving cell of the mobile terminal, and then the mobile terminal is switched to the target cell, thereby effectively This prevents the mobile terminal from switching back and forth between cells, and improves the communication reliability of the mobile terminal.

[0050] In the implementation process of the present invention, two service performance parameters are firstly defined: signal quality threshold T and long duration information P.

[0051] When the MS is selecting a candidate target BS and a target BS, it needs to determine whether the corresponding candidate target BS or the cell corresponding to the target BS meets requirements according to two defined parameters, thereby determining the correspond...

Abstract

The invention relates to a method for avoiding the ping-pang switch in wireless communication system, which comprises: the mobile terminal, in the switch process, first confirms the useful target region, and measures the service property parameter information of said target region; when the parameter meets the demand, switching the user terminal to the target region; therefore, the invention can improve the reliability of mobile terminal communication to avoid ping-pang switch, and avoid occupying lots of wireless communication resource, to reduce the effect on the property of wireless communication system.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for realizing avoiding ping-pong switching in a wireless communication system. Background technique [0002] In a mobile communication system, handover is inevitable due to the mobile characteristics of the terminal; the handover refers to handover of a mobile terminal from one serving cell (such as a base station) to another serving cell to carry out wireless communication services. [0003] In traditional cellular communication systems, handover of mobile terminals is controlled by network equipment. And in the new wireless communication system represented by 802.16, the terminal can also be used as the judge of the handover. [0004] The basis for the terminal to decide handover is only the signal quality of adjacent cells. When the terminal is at the edge of multiple cells, the signal quality of the cell is close, which may cause the terminal to switc...
