ABSTRACT:
A method for providing universal access to service features by subscribers of a wireless telecommunications service provider comprises establishing a gateway switch interconnected to a plurality of mobile switching centers maintained by other wireless service providers. Trunk connections and signaling links between each mobile switching center and the gateway switch allow the gateway switch to establish call connections and apply service features. Advantageously, the gateway switch is responsible for applying service features and establishing call connection for its subscribers and thereby, results in predictable access to wireless telecommunications services.
