Patent ID: 8781509

Claim:
A system for wireless communications, comprising: circuitry for determining a priority order between a first wireless technology and a second wireless technology, wherein the first wireless technology is different from the second wireless technology and the first wireless technology has a higher priority than the second wireless technology; circuitry to communicate, based on the determination that the first wireless technology has the higher priority than the second wireless technology, with a base station based on the first wireless technology; and circuitry to transact messages, based on the second wireless technology, with an interworking service that is in communication with a switching center associated with the second wireless technology wherein the first wireless technology comprises a Code Division Multiple Access 2000 (CDMA2000) technology and the second technology comprises a Long-Term Evolution (LTE) technology; wherein the circuitry to communicate with the base station based on the first wireless technology includes a CDMA base station controller (BSC), wherein the circuitry to transact messages based on the second wireless technology includes a Mobility Management Entity (MME), a serving gateway (SGW) and a packet data network gateway (PDN-GW), and the system includes an interworking service (IWS) module in communication with the CDMA BSC and the MME to provide the interworking service for communications to the wireless device served by the system via either the CDMA 2000 technology or the LTE technology wherein the IWS module uses a signal adaptation protocol to encapsulate messages in communicating with a wireless device served by the system.
