Proxy network layer protocol support in a wireless communication network
First Claim
1. A method of supporting a network layer protocol in a network element of a wireless communication network, comprising:
- receiving, by the network element, a first packet of a receive packet stream;
ascertaining whether the first packet conforms to a first predetermined network layer protocol; and
forwarding, at least in part in response to ascertaining that the first packet conforms to the first predetermined protocol, at least a portion of the first packet to a router, the router being configured to support the first predetermined protocol.

Abstract
A method and system for supporting a network layer protocol in a wireless communication network are presented. A network element, such as a packet data serving node (PDSN), receives, from a mobile device, a first packet of a receive packet stream. If the first packet conforms to a first predetermined protocol, then at least a portion of the first packet is forwarded to a router that supports the first predetermined protocol. The network element receives a second packet forwarded by the router. If the second packet conforms to the first predetermined network layer protocol, then at least a portion of the second packet is transmitted in a transmit packet stream. As such, the network element need not natively support the first predetermined protocol.

19. A network element for supporting a network layer protocol in a wireless communication network, comprising:
-
a first receiver to receive a first packet of a receive packet stream;
a demultiplexer operatively coupled to the first receiver and configured to ascertain whether the first packet conforms to a first predetermined network layer protocol; and
a forwarding mechanism operatively coupled to the demultiplexer and configured to forward, at least in part in response to the demultiplexer ascertaining that the first packet conforms to the first predetermined protocol, at least a portion of the first packet to a router, the router being configured to support the first predetermined protocol. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
