PROBLEM TO BE SOLVED: To provide a high-reliability and comprehensive calling party identification services to mobile subscribers. SOLUTION: Calling party identification, including public and private telephone numbers, is sent to a mobile database in a called party-side mobile network as part of an interrogation procedure for obtaining routing information for routing that call to the mobile subscriber in the PLMN. The mobile database then sends the calling party identification to a mobile switching center where the called mobile station is registered and served as a part of the interrogation procedure. The serving mobile switching center stores that calling party identification together with a roaming number allocated for the call. When the call is routed to the serving mobile switching center, the stored calling party identification is forwarded to the mobile unit along with call setup information and is ultimately presented to the mobile unit subscriber.
