Patent ID: 10142008

Abstract:
In a wireless relay, an eNodeB exchanges user data between User Equipment (UE) and a Local Gateway (L-GW). The L-GW separates the user data into Radio Area Network (RAN) user data and Wide Area Network (WAN) user data. The L-GW performs Tunneling Compression Multiplexing (TCM) on the RAN and WAN user data. The L-GW exchanges the compressed RAN and WAN user data with a data switch. The data switch exchanges the compressed RAN user data with Relay Equipment (RE) and exchanges the compressed WAN user data with an Internet Protocol Security (IPSec) agent. The RE performs Robust Header Compression (ROHC) over Long Term Evolution for a RAN data tunnel and wirelessly exchanges the compressed RAN user data over the compressed RAN data tunnel. The IPSec agent performs ROHCoIPSec for a WAN data tunnel and exchanges the compressed WAN user data over the compressed WAN data tunnel.
