Abstract
A system and method for transmitting CDMA call set-up parameters including authentication parameters through an IP-based infrastructure to an authenticating entity. A base station encapsulates, in SIP messages, CDMA data from wireless communication devices, with the headers of the messages indicating the presence of the CDMA-specific data in the message body. The SIP messages are routed through the infrastructure to an IS41 gateway, which strips the CDMA-specific data from the SIP messages and sends the necessary data to the authenticating entity for setting up a CDMA call.
