Method and apparatus for re-establishing a communication in a wireless communication system
First Claim
1. A method of re-establishing a communication in a wireless communication system, the method comprising the steps of:
- determining that synchronization on a communication channel between a mobile station and a serving base-station has been lost;
requesting, by the serving base-station, a target base-station different from the serving base station to establish synchronization with the mobile station via the lost channel; and
re-establishing the communication when synchronization between the target base-station and the mobile station is established, wherein no handoff-related signaling to the mobile station is required to effect a communication handoff from the serving base station to the target base station, and wherein the target base-station establishes synchronization and re-establishes the communication via a reserved channel, the use of which temporarily violates a channel reuse pattern associated with the target base-station.

Abstract
A method and corresponding apparatus for re-establishing a communication in a wireless communication system is disclosed. A serving base-station (32) detects that a synchronization with a mobile station (38) has been lost and chooses a target base-station (34) to attempt to establish synchronization with the mobile station (38). If synchronization is established, the communication with the mobile station (38) is re-established by the target base-station (34). The method and corresponding apparatus does not require any handoff-related signaling to the mobile station (38) to essentially effect a communication handoff from the serving base-station (32) to the target base-station (34).

10. A serving base-station in a wireless communication system, the serving base-station comprising:
-
a transceiver for transmitting and receiving a communication and synchronization information from a mobile station; a synchronization detection circuit for detecting when synchronization between the serving base-station and the mobile station has been lost; and a controller for requesting a target base-station different from the serving base-station to establish synchronization and re-establish communication with the mobile station via a reserved channel, the use of which temporarily violates a channel reuse pattern associated with the target base-station, when the synchronization between the serving base-station and the mobile station has been lost, wherein no handoff-related signaling to the mobile station is required to effect a communication handoff from the serving base station to the target base station. - View Dependent Claims (11, 12, 13, 14)

15. A wireless communication system for re-establishing a communication, the wireless communication system comprising:
- a serving base-station comprising;
means for determining that synchronization on a communication channel between a mobile station and the serving base-station has been lost; and means for requesting a target base-station different from the serving base station to establish synchronization with the mobile station via the lost channel; and a target base-station comprising; means for re-establishing the communication when synchronization between the target base-station and the mobile station is established, wherein no handoff-related signaling to the mobile station is required to effect a communication handoff from the serving base station to the target base stations wherein the target base station is arranged to establish synchronization and re-establish the communication via a reserved channel, the use of which temporarily violates a channel reuse pattern associated with the target base-station. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
