Methods and apparatus for transferring a mobile device from a source eNB to a target eNB

摘要

A method used in a wireless communication system including a plurality of cells, the method includes transmitting to a mobile device from a source enhanced node B, and sending a Packet Data Convergence Protocol (PDCP) status report to a target enhanced node B. Another method includes transmitting to a mobile device from a source enhanced node B, and sending a Packet Data Convergence Protocol (PDCP) status report to the source enhanced node B prior to a re-pointing to a target enhanced node B.

1. A method used in a wireless communication system including a plurality of cells, the method comprising:
receiving transmissions at a mobile device from a source enhanced node B; sending a Packet Data Convergence Protocol (PDCP) status report through a PDCP layer to a target enhanced node B on a radio link from the mobile device to the target enhanced node B; and resetting Radio Link Control (RLC) protocol data unit (PDU) numbering associated with a source enhanced node B link in connection with a handover operation, wherein the PDCP status report comprises PDCP sequence numbers added to RLC layer service data units (SDUs) by the PDCP layer, the PDCP sequence numbers being common to both the source enhanced node B and the target enhanced node B and distinct from RLC PDU numbering associated with the source enhanced node B link, which RLC PDU numbering associated with the source enhanced node B link is not relevant to communication with the target enhanced node B.
