Enhanced delay management

摘要

A method to facilitate user equipment (UE) handoff within a packet data communication system includes determining, at a source relay node, that the UE is to undergo a handoff from the source relay node to a target entity and sending, by the source relay node, a first request to a network node serving the UE. The sending is performed responsive to the determination that the UE is to undergo the handoff, such that the first request is configured to cause the network gateway node to store packet data addressed to the UE. Further operations include sending, by the target entity, a second request to the network, such that the second request is configured to cause the network to forward the stored packet data to the target entity, and receiving, at the target entity from the network, the stored packet data for wirelessly transmitting to the UE.

1. A method for performing a handover from a source node to a target node in a wireless communication system, the method performed by a network gateway and comprising:
receiving, from the source node which determines the handover, a store request message including information to request storing of packet data; receiving, from the target node, a forward request message including information requesting a transmission of the packet data before a synchronization between a user equipment (UE) and the target node; transmitting, to the target node, the packet data before the synchronization; completing the handover to the target node based on the synchronization.
