1. A method of communications between first and second wireless networks, comprising:
- receiving data containing a private network address of a first node in the first wireless network;
translating the private network address to a public network address; and
sending data containing the public network address translated from the private network address to a second node in the second wireless network.

Abstract
A method and apparatus for communicating between nodes in different wireless networks includes network address translators provided between the wireless networks. The network address translators are used to translate between private addresses of network elements within each wireless network to a public address. The network address translation is performed on both a network address in a header portion in each packet transmitted across a data network between the wireless networks, as well as on network address(es) contained within the payload portion of each of the packets.

10. An article comprising at least one storage medium containing instructions that when executed cause a system to:
-
receive a packet having a header portion and a payload portion from a first node in a first wireless network, the payload portion containing a private network address of the first node;
translate the private network address in the header portion and in the payload portion to a public network address; and
send the packet containing the public network address to a second node in a second wireless network. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 19, 20, 21, 22, 23, 24)

18. A system comprising:
-
an interface to a first wireless network, the interface adapted to receive a data packet containing a header portion and a payload portion, the payload portion containing a first network address of a node in the first wireless network; and
a network address translator module adapted to translate the first network address to a second, different network address associated with the node.

25. A data signal embodied in a carrier wave and comprising instructions that when executed cause a system to:
-
perform one-to-one translation of a private network address and a public network address in a packet received from a first wireless network, the private and public network addresses associated with a node in the first wireless network; and
send the packet with a translated network address to a second wireless network.
