Abstract

A communication gateway receives an Internet Protocol (IP) message sourced from a first IP address and directed to a second IP address. The gateway associates the first IP address with a code. The gateway processes the second IP address to identify a Radio Access Network (RAN) address. The gateway transfers the IP message directed to the RAN address and sourced from the second IP address. The IP message uses the code as the source port number. A base station receives the IP message, and in response to the RAN address, wirelessly transfers the IP message to a routing system. The routing system wirelessly receives the IP message and forwards the IP message based on the second IP address which is now in the source address field.
