Abstract
A network, system and method for merging a packet service such as GPRS with a mobile IP is disclosed. The GPRS network includes a first base station for providing wireless access to a mobile node, a GPRS support node (GSN) connected to the base station, and a security gateway for connecting the GPRS network to a second network that may use mobile IP. The GSN is capable of creating an IP tunnel connecting it to the second network through the security gateway. The GSN is also capable of handling mobile IP specific messaging and converting the wireless access to mobile IP specific messaging.
