ABSTRACT:
The method of transferring a CDMA data signal (107) associated with a mobile station (103) which operates between a source system (202) and a target system (204). The method includes establishing a frame relay switched virtual circuit (FR SVC) transport function capability in the source system (202) and, consequently generating a plurality of parameters. The method also includes determining that the mobile station (103) requires a transfer of the CDMA data signal (107) which results in forwarding a message from the source system to the target system to transfer the CDMA data signal (107), the message including the plurality of parameters. Based on the plurality of parameters, converting the CDMA data signal (107) into a FR SCV format by the target system (204), forming a frame relay data signal, which is routed via the target system (204) to an inter working function element (IWF)(214) of the source system (202).
