Abstract: A method and apparatus are provided for gathering statistical information on channel resource occupancy in mobile communication systems. This may provide an operator with reference materials for cell planning in a region where a base station covers and materials on increasing base stations based on a handoff holding time on each base station, by analyzing wireless environment with the channel resource statistical data gathered by counting a period while a call is set up alone by a call origination and termination as a holding time and by counting a period while a soft added call is set up by a handoff request as a handoff holding time.

Abstract: A system and method for managing communications in a packet data service network includes activating a dormant function without determining a protocol standard used by a mobile station. This is accomplished by receiving a message from the mobile station which indicates that the mobile station supports the dormant function. The message may be a service connect complete message, a state response message issued in response to a state request message from a base station controller, or a message specially formed to notify a base station controller of whether the mobile station supports a dormant function. Through the transmission and subsequent processing of this message, call processing in a packet data service network is made faster and more efficient compared with other methods.
