20120113797 | Method and Network Entity for Active Set Update in Wide Area Mobile Networks - The described method provides a Network Controller (e.g., RNC) with an active set update procedure for application when activating STTD in the 3G networks. To avoid any call drop due to misalignments between the respective transmission diversity mode configurations of cells and the presence/absence of support for transmission diversity in user terminals, STTD mode is deactivated, in cases where the terminal is rejecting the Active Set Update message due to ‘invalid configuration’. The misalignments between the respective transmission diversity mode configurations may arise in a number of scenarios: handover from a cell with STTD deactivated to a cell with STTD activated, handover from a cell with STTD activated to a cell with STTD deactivated, or handover between cells with STTD activated. In all cases the solution consists of indicating to the UE the STTD Off configuration to obtain a success active set update procedure irrespective of the true configuration status. | 05-10-2012 |
