Mobile radio system
First Claim
1. A mobile radio system having at least two mobile radio regions, comprising:
- control information and data being transmitted and received by mobile stations of mobile subscribers;
during transmission or reception, the mobile stations being wirelessly connected via air interface to radio devices of a base station system;
at least one home register in a respective mobile radio region of the at least two mobile radio regions for storage of subscriber data which is characteristic for each mobile subscriber located therein; and
at least one visitor register connected to a respective home register of the at least one home register for storage of subscriber data of the mobile subscribers who enter a responsibility area of the respective home register;
wherein before transfer of a mobile station of a mobile subscriber from an originating mobile radio region of the at least two mobile radio regions to a destination mobile radio region of the at least two mobile radio regions, the subscriber data which is stored in a home register of the originating mobile radio region is transmitted to a home register of the destination mobile radio region and is stored therein; and
wherein as soon as a radio link is produced by the mobile station of the mobile subscriber to a radio device of the destination mobile radio region, a current visitor register receives from the home register of the destination mobile radio region the subscriber data of the mobile subscriber who is entering a responsibility area of the destination mobile radio region.

Abstract
In a mobile radio system which has at least two mobile radio regions (MFA, MFB), conversion of the different signaling protocols which exist in the mobile radio regions (MFA, MFB) can be obviated since, when the mobile station (MS) of the mobile subscriber is transferred from an originating mobile radio region (MFA) to a destination mobile radio region (MFB), the subscriber data which is stored in the old home register (HLRA) is transmitted to a new home register (HLRB) which is provided in the destination mobile radio region (MFB). The mobile subscriber who is transferred to the destination mobile radio region (MFB) is then served by the home register (HLRB) present there. A home register change between the mobile radio regions (MFA, MFB) consequently takes place in response to a request from the mobile subscriber, and, in combination with the retained method of visitor register interchange within the same mobile radio region (MFA or MFB), results in a highly flexible mobile radio system.
