Abstract
To address the need for a base site and method for quickly establishing a CDMA dispatch call, the present invention provides for signaling mobile stations (e.g., 120-123) to inform them of the call and then starting the dispatch call without waiting for the call participants to request their inbound links. 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 inbound link requests are received within a period of time. Thus, the dispatch call is established while 'call setup' effectively continues.
