摘要： A layered wireless communication system (100) uses "coverage zones, i.e., coverage cells (102-108) and traffic zones," i.e., traffic cells (110-122). The traffic cells (110-122) do not require a broadcast channel carrier. In accordance with the present invention, when a call request is received (202) within one of coverage cells (102-108), either originated by a mobile or terminating with a mobile, a determination is made (208) as to whether the call can be handled by one of the traffic channel carriers within a traffic cell (110-122). If the call can be served by one of these traffic channel carriers, an assignment of the particular traffic channel carrier to service the call is made (214). Otherwise, the call is assigned a traffic channel carrier assigned to one of coverage cells (102-108).

摘要： An incident commander computing device dynamically reconfigures subscriber unit usage of radio access networks by first identifying, based at least on a type of incident occurring within a particular geographic area, a first incident response group having a first higher priority for responding to the incident and a second incident response group having a second lower priority for responding to the incident, then identifying a first higher priority radio access network having a sufficient coverage level across the particular geographic area and a second lower priority radio access network having a sufficient coverage level across the particular geographic area, and finally assigning the first incident response group to the first higher priority radio access network and assigning the second incident response group to the second lower priority radio access network.

摘要： A main microprocessor A (11) provides data to a display formatter microprocessor B (12) via a data bus (13). Microprocessor B provides data and latch (activity) pulses (34A) to a visual display (27) comprising a number of individual display devices (28-30) which are sequentially excited by data obtained from microprocessor B. An external activity detector (38), in response to an absence of the latch pulses of microprocessor B for a predetermined time, generates a reset signal (40) for resetting the microprocessor A. In response to being reset, microprocessor A provides an output control signal (at 20) which results in the resetting of the microprocessor B. If microprocessor B determines that microprocessor A is not properly providing data to it, microprocessor B will terminate generating the latch pulses (34A). The preceding configuration results in each of the microprocessors effectively monitoring the operation of the other microprocessor so as to insure proper system operation. Therefore, this system properly resets itself in response to any of a large number of different failures which may occur in either of the microprocessors, and this is accomplished with a minimum of additional hardware circuitry and software programming.
