A system and method for performing base station initiated call setup is
provided. A base station initiated call setup may be utilized to
establish a test call, to deliver a packet data services call to a
subscriber unit, or to reactivate a dormant packet call. The base station
transmits a BS Service Request message to the mobile switching center,
requesting initiation of the call. The mobile switching center will
authorize the call if the call to be set up is directed to a subscriber
unit located within the service area of the base station and if the
service option to be used is authorized for the particular subscriber
unit. The mobile switching center will allow or disallow the call
depending on the state of the subscriber unit. The mobile switching
center transmits a BS Service Response message to the base station,
conveying the result of processing the BS Service Request message. If the
base station initiated call setup is authorized and allowed, the call
will generally proceed in the same manner as a subscriber terminated
call.
