AI Technical Summary

Problems solved by technology

For some applications (such as voice over IP (VoIP) and mobile network gaming), the RoHC context needs to be rebuilt on each handover, which will cause a significant loss of capacity and / or increase latency, which in turn will cause handover In-event quality or user experience degradation

Abstract

Systems, methodologies, and devices are described that facilitate transferring a subset of compression context from a source base station to a target base station during an inter-base station handover of a mobile device to facilitate establishment of compression context between the mobile device and target base station. The source base station can transfer a subset of compression context comprising static and semi-static context to the target base station during inter-base station handover to at least partially establish compression context between the mobile device and target base station prior to or during handover. The source base station can transmit, to the mobile device, indicator information related to compression context transferred. The target base station can at least partially establish compression context based on received subset of compression context to facilitate efficient communication with the mobile device and can establish any remaining portion of compression context with the mobile device after handover.

Description

[0001] Claimed Priority Based on 35 U.S.C.S.119 [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 950,581, filed July 18, 2007, entitled "A METHOD ANDAPPARATUS FOR ROHC STATIC AND SEMI-STATIC CONTEXTTRANSFER," which is hereby incorporated by reference This application is incorporated herein in its entirety. technical field [0003] In general, the following description relates to wireless communications, and in particular, the following description relates to static context and semi-static context transfers during handover of a mobile device to another cell. Background technique [0004] Communication systems are widely deployed to provide various types of communication, for example, voice and / or data may be provided via such wireless communication systems. A typical wireless communication system or network enables multiple users to access one or more shared resources (eg, bandwidth, transmit power...). For example, the system may use ...
