METHOD FOR CONNECTING A CDMA DEVICE TO AN IP BASED NETWORK IMPLYING SIP

摘要

Users of CDMA observant devices (101) want to access services which are available on Internet Protocol based networks. In order to achieve smooth data transfer, problems with latency and data performance have to be overcome. Therefore a method for interconnecting the two different protocols is disclosed, the method comprising the steps of : - registring a CDMA mobile station (101) on an IP based network system employing a base station (115) that is configured to convert a signal from the CDMA mobile station (101) to a SIP signal; - connecting a call between an end user and the CDMA mobile station(101) through an IP based network(109); -processing said call through an IP based system (135).
