Supporting simple IP with address translation in a proxy mobile IP gateway

摘要

Methods and systems for supporting simple Internet Protocol (IP) with address translation in a proxy mobile IP (PMIP) gateway are presented. A PMIP gateway may be operable to serve wireless communication devices (WCDs) via either a PMIP mode or a simple IP with address translation mode. While the PMIP gateway is serving a given WCD in the simple IP with address translation mode, the PMIP gateway may determine that the given WCD is likely to be handed off to a network that requires the PMIP mode or a mobile IP mode. In response to making this determination, the PMIP gateway may switch to serve the given WCD with the PMIP mode.
