ABSTRACT:
A method and apparatus for avoiding the use of specially allocated, temporary roaming numbers in a mobile telephone system for routing outside calls to a mobile subscriber roaming in the system. An incoming standardized call signal frame comprising a first parameter field including a directory number is reconstructed. The directory number in the first parameter field is replaced with the unique routing number of the mobile telephone switching center within whose service area the mobile subscriber roams. A unique international mobile subscriber identity and the directory number are inserted in a second parameter field. This implies a static addressing principle in which the routing address will also contain directly the number of the called subscriber. This facilitates restoration of certain registers after a failure.
