DOWNLINK DATA OPTIMIZATION FOR PACKET SWITCHED HANDOVER |
摘要 |
<p>This invention describes a methodology for improving the performance of downlink data transfer during handovers of packet switched connections by informing the SGSN about a cell change and reducing the service interruption during the cell change. Compared to the existing procedure described in the 3GPP TS 43.129 V6. 1.0 (2004-11), the present invention eliminates the need for a cell update and a flush procedure.</p> |
