Base station and mobile unit of mobile wireless communication system, and regulation control method of mobile wireless communication system

Abstract

A wireless access inhibition can be ensured even for such mobile units that ignore regulation signals for regulating wireless accesses. There are included a control channel transmission / reception control part for controlling control channel transmissions and receptions; a control slot construction / separation part for performing control physical slot constructions and separations based on a control of the control channel transmission / reception control part; a traffic concentration determination part for monitoring the traffic status of wireless lines to determine whether the traffic is concentrated; and a unique word pattern storage part for storing a unique word pattern to be designated when the control channel transmission / reception control part sends a control physical slot construction request to the control slot construction / separation part. When regulating the accesses from mobile units to the base station based on the monitor result of the traffic concentration determination part, the control slot construction / separation part changes the unique word pattern to be set in the control physical slot to a pattern other than the patterns as specified in standards.

Description

Base station of mobile radio communication system, mobile machine, and limitation control method of mobile radio communication system technical field The present invention relates to a mobile wireless communication system constituting a base station, a mobile device, and a mobile wireless communication system restriction control method for restricting the use of a wireless line between the base station and the mobile device. Background technique Recently, various mobile wireless communication systems are operated by a plurality of communication carriers, and the number of users thereof is further increasing. On the user side, the frequency of use is increasing due to its convenience, and communication traffic is also rapidly increasing due to the diversification of usage forms such as mail and content services. Not limited to mobile wireless communication systems, in communication systems, if calls and traffic are concentrated in a specific area, the communication path wi...

Problems solved by technology

However, in the conventional wireless communication system for mobiles disclosed in the aforementioned Patent Document 1, etc., in the barring control method that transmits the barring signal, when the mobile station cannot understand the barring signal transmitted, or ignores the barring signal In the case of , there is a problem that limit control does not work, and the load on the base station where the traffic is concentrated cannot be reduced.

In addition, in the restriction control method based on ON / OFF of the control channel, if the base station stops the control channel for restriction, the service area constituted by the base station does not exist. Therefore, while the base station stops transmission of the control channel, the When a new base station constituting a service area starts to operate at the same position as the service area originally constituted by the base station, there is a problem that interference is detected in the base station when the restriction is to be lifted, and in order to utilize the original service area It takes more than the stipulated time, or may not be able to use the original service area
