ABSTRACT:
To address the need for an apparatus and method for quickly establishing a CDMA dispatch call, the present invention provides for paging mobile stations (e.g.,120-123) to inform them of the call and then starting the dispatch call without waiting for page responses from the call participants. The dispatch call is first transmitted by base sites (e.g.,110-112) of all the service coverage areas (e.g.,101-103) that may have call participants, and then discontinued at those base sites where no page responses are received within a period of time. Thus, the dispatch call is established while “call setup” effectively continues.
