A METHOD AND A SYSTEM FOR MANAGING CELL SELECTION IN A WIRELESS NETWORK SYSTEM

Document Type and Number:

WIPO Patent Application WO/2013/051871

Kind Code:

A1

Abstract:

In LTE advanced networks, Carrier aggregation allows expansion of effective bandwidth delivered to a user terminal through concurrent utilization of radio resources across multiple carriers. In the scenario when the MBMS transmissions are scheduled in only one band or cell the idle mode UEs that would like to receive MBMS service would like to camp onto the cell or frequency that supports MBMS services. This can lead to more UEs being camped onto a cell or frequency that supports MBMS rather than cells that do not support MBMS services. Such scenarios lead to congestion of certain cells/frequencies than others. In order to mitigate such overload conditions, there is a need to enforce appropriate camping behaviors as well as make sure that proper convergence and dispersion mechanism are in place in Carrier Aggregated LTE networks supporting MBMS. In order to address the above problems, this invention discusses idle mode specific aspects related to MBMS service continuity, in particular this invention covers aspects covering the issue of convergence, dispersion and prioritization of cells when the user equipments are in idle mode.
