Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0021] The method of the present invention predefines the handover area with high success rate on the network side, and performs area control on the inter-office handover operation, thereby reducing the transmission burden between the base station and the switch and the switching burden on the network side itself, and improving the success of the inter-office handover on the network side. efficiency, reducing the occupation of network-side handover resources by invalid inter-office handover processes.
[0022] Of course, according to the agreement, when the handover is in progress, the current service of the mobile station is normally carried out no matter whether the handover fails or not.
[0023] Fig. 1 is a method flowchart of the present invention, and the present invention comprises the following steps:
[0024] Step 11. Obtain the inte...

The method includes following steps: the switching statistical data of interoffice of current office is obtained, the switch area of neighboring office is made attribute value definition according to switching success rate and cause value of switching failure, and a control table of interoffice switching area is built; the interoffice switching happens in operation of mobile station; the communication network identifies the switching area according to the attributes value of the switching area; the request of building communication channel originated by the switch area is transmitted or is refused to transmit to the switching response side of the communication system; after the above response side receives the request, a communication channel is built between the base station at response side and the base station at control side, and waits access of the above mobile station.
Description
technical field [0001] The invention relates to a method for improving the success rate of inter-office switching in the field of mobile communication, in particular to a control technology for the external switching process of a time division multiple access digital cellular mobile communication network. Background technique [0002] The mobile station is always in constant motion, and its location information is also constantly changing. When the mobile station performs calls, supplementary services, etc., as part of the BSS (Base Station Subsystem) function, the base station will generate a handover request message to the network side at an appropriate time. The network side generally performs operations such as handover request indication, handover resource allocation, and handover execution. During this process, the handover master side of the network often encounters situations such as unavailability of ground resources requested by the handover response side, failure...
