METHOD AND APPARATUS FOR CONTROLLING RELAY STATION MODE OF MOBILE STATION IN A COMMUNICATION SYSTEM
First Claim
1. A method for a Mobile Station (MS) to control a Relay Station (RS) mode of the MS in a communication system, the method comprising:
- sensing a link loss with a serving Base Station (BS);
searching for a neighbor BS for network reentry;
transmitting to the neighbor BS an Identifier (ID) of the serving BS and an indication indicating network reentry from coverage loss caused by movement out of a service area of the serving BS; and
operating in the RS mode, upon receipt of an indication commanding switch to the RS mode from the neighbor BS,wherein the RS mode is a mode in which the MS operates as an RS.

5. A method for a Base Station (BS) to control a Relay Station (RS) mode of a Mobile Station (MS) in a communication system, the method comprising:
-
receiving from the MS an Identifier (ID) of a link-lost serving BS and an indication indicating network reentry from coverage loss caused by movement out of a service area of the serving BS; determining whether the serving BS cannot service any MS within the service area of the serving BS in an out-of-service state; and transmitting an indication commanding switch to the RS mode to the MS, if the BS is in the out-of-service state, wherein the RS mode is a mode in which the MS operates as an RS. - View Dependent Claims (6, 7, 8)
