Abstract
A system and method for conveying data in an inter-exchange message, said data identifying a selected one of a plurality of mobile station identifiers to be used in connection with a particular mobile station. The mobile station selects said mobile station identifier prior to registering with a first mobile switching center. Subsequently, the mobile station moves into an area served by a second mobile switching center. An inter-exchange message containing information about the mobile station is then sent from the first mobile switching center to the second mobile switching center. The information includes the plurality of mobile station identifiers and an indication of which one of the identifiers has been selected for use by the mobile station. The selected identifier can then be extracted from the inter-exchange message and used by the second mobile switching center for paging the mobile station, for compiling statistics relating to the mobile station, or for other purposes in implementing the mobile telecommunications system.
