摘要:
A method quickly resuming a downlink service in a hard handover in a cellular mobile communication system. To provide the fast downlink service to an MS during a hard handover from an OBS to an NBS, the NBS receives handover user information from the OBS, and generates an MS temporary ID using the handover user information to identify the MS. If user data is generated for the MS before a connection is established for traffic transmission between the MS and the NBS, the NBS transmits the user data to the MS on an HCCH using the MS temporary ID.

An apparatus and method for power saving in a wireless communication system are provided. The method includes performing scheduling considering a channel state of at least one MS located in a service area during an ith scheduling interval, confirming if there is an MS not to be selected at an (i+1)th scheduling interval according to the scheduling result of the ith scheduling interval, and if there is at least one MS not to be selected, controlling the MS not to estimate a channel for scheduling of the (i+1)th scheduling interval.
摘要:
A handoff method in a communication system where BSs providing different radio access interfaces to an MS are connected to an IP-based network through routers. A handoff from a first BS to a second BS is decided for an MS that receives IP service data from the first BS and an L2 connection is established between the MS and the second BS. During the L2 connection establishment, movement of the MS in the IP network is detected. Handoff negotiations are conducted between the first and second BSs by IP signaling. If the handoff is available according to the negotiations, mobility management control is performed considering movement of the MS. The IP service data is transmitted to the MS in a network path reset to the second BS by the mobility management control and an L2 connection is released between the MS and the first BS.
