Embodiment Construction

[0019] Various aspects will now be described with reference to the accompanying drawings. In the following description, for purposes of explanation, various specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such arrangements may be practiced without these specific details.

[0020] Several aspects of a communication system will now be provided with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, procedures, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or a combination thereof. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the over...

Abstract

Methods and apparatus are described herein to manage a serving cell change. A HS-SCCH monitored set is maintained to store entries for all pending serving cell change requests. The HS-SCCH for each entry is monitored for a timer period. Once a change request has been confirmed for one entry, monitoring for the other entries continues until expiration of the associated timers.

Description

[0001] Priority claim based on 35 U.S.C. §119 [0002] This patent application claims the priority of the provisional application No.61 / 174,705 with the title of "Method to Increase Reliability of an HSDPA Enhanced Serving Cell Change (ESCC) Procedure" submitted on May 1, 2009. The provisional application The entire content of is incorporated herein by reference. technical field [0003] The present application relates generally to wireless communications, and more particularly to handling handoffs during wireless communication sessions. Background technique [0004] Enhanced Serving Cell Change (ESCC) is a feature in 3GPP Release 8 designed to improve the reliability of the serving cell change procedure. During the ESCC procedure, the network receives a serving cell change request, and an event 1d (eld) measurement report message (MRM), and decides to perform a serving cell change. The network does not send a physical channel reconfiguration message on the HSPDA link of t...
