METHOD AND APPARATUS FOR SIGNALING INTERWORKING CDMA 3G1x MOBILES AND EVDO MOBILES WITH AN IMS CORE NETWORK
First Claim
1. A method of interworking a 3G1x call control and signaling with session initiation protocol signaling comprising:
- receiving an incoming code division multiple access mobile message from an associated mobile station;
mapping between said code division multiple access mobile message and a session initiation protocol message through a basestation emulator and signal initiation protocol user agent; and
sending said session initiation protocol message to an associated internet protocol multimedia subsystem.

Abstract
A basestation 3G1x network architecture which is used to convert 3G1x control and signaling to IMS/SIP in basestation is disclosed. The system includes a user agent that bi-directionally translates between SIP messaging and CDMA messaging. The system also includes a 1x basestation emulator which may act as an interface for the 3G1x handset. The basestation emulator is also configured to terminate CDMA mobile protocol and interconnect messages and operations with the user agent. The methods include mapping between the CDMA mobile message and the SIP message through the basestation emulator and the SIP user agent. The method may facilitate basestation origination and termination as well as feature services. These feature services may include three way calling, call waiting and call waiting with caller identification.
