Abstract

A mobile communications system in which a mobile subscriber may roam includes a number of exchanges having coverage areas in which the mobile subscriber may roam. An interrogation exchange receives incoming calls to the mobile subscriber and requests information as to the location of the mobile subscriber from its home exchange. The home exchange includes a list of a plurality of possible exchanges in which the mobile subscriber may be located which is used to supply information as to the location of the mobile subscriber. The home exchange initiates and coordinates the paging process and reacts according to the outcome of this process.
