Abstract: A system and method of evaluating the radio coverage of a geographic area serviced by a digital cellular radiotelephone communication system is described which comprises a plurality of base stations each having a transmitter and a receiver and a plurality of mobile units having co-located transmitters and receivers for transmitting and receiving communication message signals between the base stations and a mobile unit. During operation, the position of at least one of the mobile units operating within the geographic area is located when a call is received by a base station. The base station monitors the signal quality of the call and collects information relevant to the actual performance of the communication system.

Abstract: The method of conveying control and program information between cellular radiotelephone controllers and of detecting information errors is disclosed. When a program memory information error is detected, a predetermined amount of memory information is conveyed from a first controller to a second controller. If a comparison of checksums of a predetermined amount of memory information stored at the second controller and the memory information received from the first controller matches, additional memory information is conveyed. If a match is not found, the predetermined amount of memory information is reconveyed from the first controller to the second controller.

Abstract: The method and apparatus for interfacing between a cell site controller, a cell system controller, and the radio transceivers of a cellular radiotelephone system is disclosed. To convey control information to the radio transceivers, the cell site controller enables one of a redundant pair of control data buses to a selected transceiver by placing an enable signal on the enable line unique to the selected transceiver. Control data is then coupled to the common enabled control data bus for conveyance to the selected transceiver. The transceiver mutes the message data port it may be using and transponds the control data information it receives. When the enable signal is removed, the transceiver unmutes the message data port. Program information is transferred between the cell system controller and cell site controllers as memory blocks which may be retransferred upon detection of a checksum mismatch.

Abstract: A method and apparatus for utilizing voice channel transceivers as temporary scanning receivers in a handoff event for a cellular radiotelephone system is disclosed. Voice channel transceiver identifications are stored in link lists according to priority, sectorization, and last use. When a signal strength measurement is required, those cell sectors having available voice channel transceivers are identified and a table providing optimum transceiver selection is utilized to select those voice channel transceivers which will make the signal strength measurement.
