Method for improving handover success rate of group mobile terminals, mobile agent and mobile terminal

Abstract

The embodiment of the invention provides a group moving terminal switching success ratio improving method, a mobile agent and a mobile terminal, wherein the method comprises the following steps of: obtaining the minimum avoiding time value according to the obtained access parameters; receiving messages sent by the mobile terminal after entering a new cell; sending the messages to a base station when the messages are switching requesting messages; starting to time after receiving the messages which are not switching requesting messages and sending the received messages to the base station when the timing reaches the preset time. The preset time is greater than or equal to the minimum avoiding time value, the minimum avoiding time valve is the minimum time value capable of being obtained by the preset time when the received messages sent by the mobile terminal are not the switching messages. The embodiment of the invention has the advantages that the defect of high switching failure rate of the group moving terminal switching method in the prior art can be overcome, and the group mobile terminal switching success ratio is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a method for improving the handover success rate of group mobile terminals, a mobile agent, a mobile terminal and a communication system. Background technique [0002] Modern public land mobile communication networks are based on a cellular architecture in which location management is a core technology. Location management includes two contents: one is to track the location of the mobile terminal in idle mode, and the other is to ensure that the mobile terminal can still maintain service continuity after the location changes. The latter is called handover technology. In existing cellular networks, two-level location management is usually adopted. The first level of location management is a cell, and the second level of location management is a location area (Location Area, LA for short), and one location area includes multiple cells. If the l...

Problems solved by technology

[0005] The problem existing in the cellular network group mobile terminal handover technology in the prior art is: figure 1 For example, when a high-speed vehicle enters the location area, the mobile terminal on the high-speed vehicle will generate a switching request and a location update request

When a high-speed vehicle crosses from one location area to another location area, the edge cell of the target location area will not only generate a handover request message sent by the group mobile terminal, but also generate a location update request message sent by the group mobile terminal. The number of location update request messages sent by the terminal is far greater than the number of handover request messages, thus further increasing the handover failure rate
