A radio switching system includes a mobile subscriber; a base station controller for controlling a transmission and reception of a signal of the mobile subscriber within an own cell; a mobile switching center connecting with a plurality of the base station controllers; and a home location register for storing home zone information whether or not the mobile subscriber is a subscriber of home zone services. The mobile switching center judges whether or not a registration is accepted with respect to a location registration request inside/outside a home zone of the mobile subscriber, based on home zone information sent from the home location register.
Claims9
A radio switching system comprising:
- a mobile subscriber;
- a base station controller for controlling a transmission and reception of a signal from the mobile subscriber within its own cell;
- a mobile switching center connecting with a plurality of base station controllers;
- and
- a home location register for storing home zone information indicating whether or not the mobile subscriber is a subscriber of a home zone service, which restricts a moving area of the mobile subscriber, wherein
- the mobile switching center judges responsively to a position registration request inside/outside a home zone, which is a cell and location registration area or another newly defined zone unit, by the mobile subscriber, whether or not the registration is accepted in the home zone, based on the home zone information transmitted from the home location register, and
- wherein each time a radio area is changed by a hand-over of the mobile subscriber, the mobile switching center further receives a hand-over request, first selects a hand-over destination by judging whether or not a base station controller as a hand-over destination candidate is under control of the home zone, and in the case where the hand-over destination candidate is under control of the home zone, renews and stores the number of times of hand-over and hand-over area information to transmit to an accounting center as accounting information, so as to utilize an accounting calculation.
