Abstract
Techniques for providing enhanced wireless services such as interactive voice services to a serving mobile switching center which is originating a call for a mobile station that requires such services via the public switched telephone network (PSTN). The serving mobile switching center has a trigger which causes it to respond to a call from the mobile station by sending a message according to the IS 41 protocols to the enhanced mobile switching center that provides the enhanced service. The enhanced mobile switching center responds to the message by associating the contents of the message with a temporary local dialing number (TLDN) and sending a message to the serving mobile switching center that contains the TLDN. The serving mobile switching center uses the TLDN to set up a call via the PSTN to the enhanced mobile switching center, which then uses the content of the message associated with the TLDN to establish which enhanced service is required. It calls the service node for the enhanced service and bridges the call from the serving mobile switching center to the service node. The call provides a voice channel for the enhanced service.
