Problems solved by technology

Therefore, it is inconvenient for the mobile station side in case of emergency, etc., and reliability may be affected. Therefore, it is desired to realize a wireless communication system that improves these situations.
[0016] As mentioned above, in order for the mobile station to communicate in the above-mentioned wireless communication system, the mobile station first performs a paging operation, and the base station performs a detection operation for whether there is a free time slot in the communication channel. It is inconvenient for the mobile station side to communicate with the other party in an emergency, etc., and affects reliability, so it is desired to realize a wireless communication system that improves these situations

Abstract

A radio communication system includes a line controller, a plurality of base stations connected to the line controller and a plurality of mobile stations connected to each of the plurality of base stations by radio communication line having control channel and communication channel, and each of the plurality of base stations includes a control unit for monitoring idle slot in the communication channel within a communication area of the base station. The control unit transmits the monitored information of the idle slot to the mobile station within the communication area of the base station at predetermined intervals by using the control channel and each mobile station can use an idle slot in the base station or, if there is no idle slot in the base station, in another base station based on the monitored information of the idle slot to make communication.

Description

technical field [0001] The invention relates to a wireless communication system, in particular to a wireless communication method and system for channel notification of a digital mobile communication system. Background technique [0002] Currently, as one of the digital wireless systems that are being put into practical use, there is a mobile communication based on "REGIONALDIGITAL MOBILE TELECOMMUNICATION SYSTEM", ARIBSTD-T79, Ver.1, Association of Radio Industries and Businesses, June 6, 2001, pages 1-24 system. Fig. 11 shows a general mobile communication system having a plurality of base station areas. In FIG. 11 , 1101 denotes a line control device, 1102-1 and 1102-2 denote base stations, and 1103-1 and 1103-2 denote base station areas, that is, communication areas of respective base stations. The base station 1102-1 is a system configured to communicate between a plurality of mobile stations 1104-1, 1104-2, ... 1104-N located in the communication area 1103-1 and the ...
