Abstract
Methods, systems and mobile switching centers are provided that communicate a service code designation over a public switched telephone network without requiring two stage dialing. A received service code, for example a request for facsimile transmission services, is converted by the mobile switching center receiving the request to a pilot number. Pilot numbers are coherently (uniquely) associated with each of the possible service codes supported by the communication protocol (such as IS-136) but are in a form which, unlike the service codes, may be transmitted over the PSTN. The conversion may be provided, for example, by a look up table maintained by the mobile switching center. On the destination end, the receiving wireless network mobile switching center may then convert the pilot number to a service code and establish a connection supporting the requested service to the destination device. Accordingly, the wireless device providing the service code may request services for a communication including establishment of a communication channel including the PSTN in the same manner as where the service is provided entirely by wireless networks which support communication of the service codes.
