Method and apparatus for providing service availability information in a wireless communication system
Abstract
A method and apparatus for providing service availability information includes receiving a signal transmitted from a base station. A power level and interference level of the received signal is measured and an estimate of a power level of each potentially available service based on the power level of the received signal and predetermined power offsets associated with each of a plurality of potentially available services is derived. An estimate of a signal-to-interference ratio (SIR) for each potentially available service from the estimate of a power level of each service and the measured interference level and a service availability indicator for each potentially available service by dividing the estimated SIR with a target SIR are calculated. Service availability indicators for each potentially available service are outputted.
