Method and system for dynamically regulating a power saving period within a radio telecommunication system
First Claim
1. A radio telecommunication system including a plurality of cell sites individually taking charge of predetermined areas and mobile stations having a function of intermittently receiving signals,each of said plurality of cell sites comprising:
- a cell site internal timer for sensing the time;
a cell site memory storing a mobile station identification periodically transmitted from each mobile station, battery-saving receiving period information, and battery-saving receiving time in association with each other; and
a cell site control unit rendering said cell site memory to store therein blocking information indicating that blocking has occurred, in case a paging signal is sent to a mobile station in an area in response to a paging request made by a PBX (Private Branch Exchange) or a public switched telephone network control unit and an answer is not returned from the mobile station in response to the paging signal, in said cell site memory so as to be associated with a mobile station ID on said cell site memory and inform the mobile station of the blocking information according to the information on said cell site memory, andeach of the mobile stations comprising;
a mobile station internal timer for sensing the time;
a mobile station memory storing battery-saving receiving period information to intermittently exercise on /off control over a receiving unit; and
a mobile station control unit periodically transmitting said battery-saving receiving period information to a cell site and increasing /decreasing the battery-saving receiving period information on said mobile station memory according to presence /absence of blocking information fed from said cell site to control the battery-saving receiving period.

Abstract
A mobile radio telecommunication system and method provide battery-saving receiving of mobile stations. The mobile station autonomously changes the period of intermittence according to the frequency of paging in order to reduce the power consumption of the mobile station. When there has not been paging processing for a fixed time, the mobile station autonomously prolongs the period of intermittence and reregisters a new period of intermittence. In case there has been paging processing, the mobile station shortens the period of intermittence. If blocking has occurred for paging from the cell site, the cell site incorporates blocking information into a broadcast signal, informs the mobile station of occurrence of blocking, and registers a new period of intermittence.

6. In a radio telecommunication system including a plurality of cell sites individually taking charge of predetermined areas each site having a cell site memory and mobile stations having a function of intermittently receiving signals each station having a mobile station memory, a radio telecommunication method for holding down blocking to the minimum and reducing the power consumption in the mobile station, comprising the steps of:
-
storing, in the cell site memory of each cell site, a mobile station identification periodically transmitted from a mobile station existing in each area, battery-saving receiving period information, and battery-saving receiving time, so as to be associated with each other, in a cell site memory by using a cell site internal timer for sensing time; storing blocking information indicating that blocking has occurred, in case a paging signal is sent to a mobile station in an area in response to a paging request made by a PBX (Private Branch Exchange) or a public switched telephone network control unit and an answer is not returned from the mobile station in response to the paging signal, in said cell site memory so as to be associated with a mobile station ID on said cell site memory; informing the mobile station of the blocking information according to the information on said cell site memory; storing, in the mobile station, battery-saving receiving period information to intermittently exercise on /off control over a receiving unit, by using a mobile station internal timer for sensing the time; and periodically transmitting said battery-saving receiving period information to a cell site and increasing /decreasing the battery-saving receiving period information on said mobile station memory according to presence /absence of blocking information fed from said cell site to control the battery-saving receiving period.
