A method of determining whether a wireless packet data service can be
activated in a dormant state. To activate one of a plurality of packet
data services in the dormant state, a BS transmits to an MS a Page
Message containing an SR ID identifying the service to be activated. If a
service instance for the service is unavailable, the MS transmits to the
BS a response message indicating that the service cannot be reconnected.
The BS then terminates immediately, thereby saving radio resources and
improving system performance.
