A SYSTEM AND METHOD FOR UTILIZING A SHARED NETWORK HAVING ONE MOBILE NETWORK CODE

摘要

A system and method of selecting a network operator by a roaming subscriber in a shared network. The method begins by a roaming subscriber, UE, entering the shared network. A query is provided to the UE of a selection of at least two network operators operating within the shared network. The subscriber then selects a desired network operator for use in the shared network. The selection is sent and stored in a VLR in the shared network. A call is initiated by the UE in the shared network and routed in accordance with the selected network operator. Preferably, the UE sends a USSD string providing the desired network operator to the VLR. The USSD string triggers a USSD application for using the selected network operator.
