Embodiment Construction

[0020] Embodiments disclosed herein may be implemented in any wireless and / or wired communication system, such as cellular networks, public switched telephone networks (PSTNs), wireless Internet, satellite networks, wide area networks (WANs), wireless area networks (WLANs) ), VoIP network, IP-based multimedia system, etc.

[0021] 1 illustrates an example of a communication system 10 that may implement one or more methods described herein. A first access terminal (AT) 100A may include an uplink (or reverse link) header compressor 102 . In a radio access network (RAN), a first access terminal 100A may communicate wirelessly via a reverse link (RL) with a base station 104A and a base transceiver system / packet data serving node (BTS-PDSN) 106A.

[0022] BTS-PDSN 106A may include an uplink header decompressor 110, which may perform one or more of the methods described herein. BTS-PDSN 106A may communicate with Packet Data Serving Node / Base Transceiver System (PDSN-BTS) 106B via ...

Abstract

Methods and systems to enhance local repair in robust header compression (RoHC) decompressors (110, 114), which may improve network transmission efficiency and quality. One method uses lower layer information to enhance local repair at the decompressor (110, 114). Another method uses a user datagram protocol (UDP) checksum to enhance local repair at the decompressor (110, 114).

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application claims Serial No. 60 / 798,058, filed May 4, 2006, entitled "METHODS AND SYSTEMS FOR ENHANCING LOCAL REPAIR INROBUST HEADER COMPRESSION" priority to the Provisional Application, which is assigned to the present assignee and is hereby expressly incorporated herein by reference. technical field [0003] The present application relates generally to wireless communications and, more specifically, to methods and systems for enhancing local repair in robust header decompression. Background technique [0004] Internet Protocol (IP) is a network protocol used in both wired and wireless networks. For certain services and applications (eg, Voice over Internet Protocol (VoIP), interactive games, messaging, etc.), the payload of an IP packet may be nearly the same size as or even smaller than the packet's IP header. There may be significant redundancy in header fields within the same packet header and especi...
