Selected identifiers belonging to the wireless communications device are provided to a network entity based upon the control function being processed, or more generally, upon the class of control function being processed. In one embodiment, a Mobile Switching Center (MSC) receives a plurality of identifiers and a control function request from a wireless communications device. The MSC determines which of the identifiers are needed by the network entity to process the requested control function based on the control function requested. The MSC filters the received identifiers to remove un-needed identifiers based on its analysis and forwards the filtered identifiers to the network entity and/or to another network. In another embodiment, the present invention pushes the determination of which identifier to send downward to the wireless communications device itself. In these embodiments, the wireless communications device is programmed to determine which identifier is needed, and this identifier is transmitted to the MSC with the control function message. This determination by the wireless communications device of which identifier is needed is independent of the network, not simply a response to a command from the network. The present method helps insure that the proper identity is sent by the MSC to other network entities when the wireless communications device includes more than one fixed identifier. The method is particularly adapted for situations where the wireless communications device includes a subscription module having a subscription module identifier and mobile terminal having a mobile terminal identifier. |
