Mobile radio communication system and method of registering position therein
First Claim
1. A method of registering position in a mobile radio communication system in which a position registration area number is reported from a base station to a mobile station within a radio zone, position information indicating a position registration area in which a mobile station resides is registered in storage means based upon position registration information that has been transmitted from the mobile station, and when there is an incoming call to a mobile station, a paging call is placed from a plurality of base stations within the position registration area, in which said base station resides, based upon position information that has been read out of said memory means, comprising steps of:
- registering a rule for predicting the timing when a mobile station changes a position registration area by moving;
checking, on a per-mobile-station basis, whether a state in which said rule is applicable has been attained; and
updating the position registration area of said mobile station based upon said rule if the state in which the rule is applicable has been attained.

Abstract
Disclosed is a mobile radio communication system in which a position registration area number is reported from a base station to a mobile station within a radio zone, position information indicating a position registration area in which a mobile station resides is registered in storage means based upon position registration information that has been transmitted from the mobile station, and when there is an incoming call to a mobile station, a paging call is placed from a plurality of base stations within the position registration area, in which the base station resides, based upon position information that has been read out of the memory means. Updating of the position registration area of a mobile station can be performed automatically on the network side without the mobile station transmitting position registration information to the network side. To achieve this, a rule for predicting the manner in which a mobile station will change a position registration area by moving is registered beforehand on the network side. Whether a state in which the rule is applicable has been attained is checked for every mobile station. If such a state is attained, the position registration area of the mobile station is updated based upon the rule.

10. A mobile radio communication system in which a position registration area number is reported from a base station to a mobile station within a radio zone, position information indicating a position registration area in which a mobile station resides is based upon position registration information that has been transmitted from the mobile station, and when there is an incoming call to a mobile station, a paging call is placed from a plurality of base stations within the position registration area, in which said base station resides, based said position information, comprising:
-
means for storing a rule for predicting the timing when a mobile station changes a position registration area by moving; storage means for storing position information indicating a position registration area in which a mobile station resides; and a position registration controller for obtaining a position registration area of a mobile station based upon said rule if a state in which said rule is applicable has been attained on a per-mobile-station basis, and updating said position information.

11. A mobile station in a mobile radio communication system in which a position registration area number is reported from a base station to a mobile station within a radio zone, position information indicating a position registration area in which a mobile station resides is based upon position registration information that has been transmitted from the mobile station, and when there is an incoming call to a mobile station, a paging call is placed from a plurality of base stations within the position registration area, in which said base station resides, based said position information, comprising:
-
means for receiving and storing a rule, in accordance with which a position registration area is changed by movement, from a network side; and position registration control means for checking whether a state in which said rule is applicable has been attained and halting transmission of position registration information if the state in which the rule is applicable has been attained. - View Dependent Claims (12, 13)
