To enable a scalable system, the SIP BEs are decomposed into separate communicating entities that male the SIP BE scalable and provide new capabilities not previously available by a self-contained SIP BE. Further, multiple levels of decomposition of a SIP BE can be provided by the present invention supporting a flexible and scalable SIP BE design that further improves system efficiencies and cost advantages as compared to use of single integrated border or edge elements. Further, a scalable SIP BE, made up of a plurality of physical entitles for optimization of a large scale design, acts as a single integrated functional entity to logically execute a set of functions at the border of a VoIP infrastructure.

Title: Apparatus and method for handling cell update during reconfiguration in universal mobile telecommunications system user equipment
Inventor: HARRISON ROBERT J
IPC: H04W88/02
Filed: 2004-09-24
Abstract: The details of an apparatus and method for handling cell update during reconfiguration in universal mobile telecommunications system user equipment are disclosed herein. When a UE receives a Reconfiguration request from a UTRAN, it sets an activation time for execution of the reconfiguration. Where a cell update is required when the reconfiguration has not yet been applied, the UE delays the execution of the cell update procedure until after the reconfiguration has been applied. If the trigger which initiated the cell update procedure is no longer relevant, the cell update is unnecessary and may be cancelled.
