Reliable and comprehensive calling party identification services are provided to mobile subscribers. Calling party identification information, including for example public and private telephone numbers, is sent to a mobile database in a called party 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 currently registered and being served as part of that 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. |
