Provided is a method and system for enabling mobile devices, radio access networks (RANs), and core networks (CNs) based on different specifications and underlying technologies to communicate. The mobile device and the RAN may be based on one technology, such as a code division multiple access (CDMA) specification, while the CN may be based on another technology, such as a global system for mobile communications (GSM) specification. The method takes a CDMA message received by the RAN, converts it into a corresponding GSM message, and passes it to the CN. Alternatively, a new GSM message may be created. Similarly, a GSM message from the CN may be converted into a CDMA message (or a new CDMA message may be created) and the CDMA message passed on to the RAN. The method may also initiate a function or procedure in one portion of a network using one technology when a certain message is received from another portion of the network using a different technology. This provides a cost-effective and flexible process that, among other advantages, enables the mobile device to communicate with incompatible CNs.
