Patent ID: 8488582

Claim:
A method of producing reduced packet size in a Generic Access Network (GAN) user plane comprising the steps of: (a) defining an Encapsulating Security Payload (ESP)/User Datagram Protocol (UDP)/Internet Protocol (IP) profile for Robust Header Compression (ROHC); and (b) using the ESP/UDP/IP profile to compress an outer IP segment of a packet carrying Internet Protocol Security (IPsec) ESP tunnel traffic in the GAN user plane at a device; (c) using a Real-time Transport Protocol (RTP)/UDP/IP profile for ROHC between an ingress IPsec ESP tunnel endpoint and an egress IPsec ESP tunnel endpoint for additional compression of the packet including compressing an inner IP segment at said device while the ESP/UDP/IP profile is used to compress the outer IP segment of the packet; wherein said outer IP segment is decompressed before it leaves a wireless access point and said inner IP segment is decompressed before it leaves a Services Security Gateway (SeGW).
