Method of raising successive mobile station accessing rate in mobile communication system

Abstract

A method to raise entering success rate of mobile station in mobile communication system is to measure the signal quality of adjacent area base station of the current area after the mobile station isstayed at the current area and it will select the adjacent area which signal quality is in accordance with the set condition to fetch its system broadcast information as well as to select proper areaas an entering candidate area according to the registering authorization in system broadcast information. The mobile station will maintain the relative information of entering candidate area so that the mobile station can entercommunication system through entering the candidate area for normal communication when the mobile station is required at communication but the communication system can not be entered through the current areary.

Description

technical field [0001] The invention relates to a method for improving the access success rate of a mobile station in the field of mobile communication. Background technique [0002] In the mobile communication system, the mobile station as a mobile communication terminal moves in each adjacent cell, and each cell has a base station, and the mobile station communicates with other mobile stations or fixed users by establishing a connection with the base station. After the mobile station enters a certain cell and completes location registration, it camps in the cell and enters an idle state. This cell is the current cell of the mobile station. [0003] In the idle state, if the mobile station moves from one cell to another, the mobile station performs the cell location update process, or needs to respond to the paging from the base station of the cell, or the mobile station needs to communicate with other mobile stations or fixed Calls, including service requests, sending sho...

AI Technical Summary

Problems solved by technology

If the random access is unsuccessful, the mobile station cannot perform data interaction with the current cell, and cannot complete the call or data transmission function

[0004] In the current mobile communication system, there is always one current cell where the mobile station resides, and the access slot resource of a base station in a cell is limited. When entering the time slot, access conflict is likely to occur, resulting in the failure of the access process; especially in densely populated cities and hotspot areas, this situation is very likely to occur

In addition, if the current load of the cell base station is heavy, it may also reject the access requests of other mobile stations, resulting in the inability of other mobile stations to establish a connection with the current cell base station for normal communication

Moreover, in the prior art, the mobile station is limited to access in the current cell where it resides. If the mobile station cannot access through the current cell, even if the adjacent cell has idle access resources and allows access, the mobile station cannot Utilization, therefore, the existing technology does not fully utilize the access resources of the entire system to improve the access success rate of the mobile station
