    摘要: A personal communication system (100) having power control provided by a radio port control unit (122), provides for portable radio controlled optimum base station selection. Multiple base stations 102, 124, and 130 transmit channel signals including a code word which indicates the transmit power level of each transmission. A portable radio 120 measures the received signal strength (RSS) of each of the channel signals transmitted from the base stations and also receives the coded power levels of each transmission. The portable (120) then calculates an adjusted received signal strength (ARSS) value for different channels from different base stations. The portable (120) then compares the ARSS values to determine the optimum base station to communicate with for portable controlled handover, local registration, and link set up.

    摘要: A method and apparatus whereby a communication unit (10) transmits a communication channel request and the nearest base site (12) makes the communication channel grant or allocation. A base site receives the channel request signal, measures the received signal strength (RSSI) level of the received signal, and if that level is above a threshold level, a communication channel is allocated to the requesting communication unit, thus establishing a communication link. If the channel request signal does not have an RSSI level above the threshold, the base site delays the grant of a communication channel for a period inversely proportional to the measured RSSI level to allow other base sites the opportunity to grant a communication channel to the requesting communication unit. If the base site determines that another base site has granted a communication channel to the requesting communication unit, the allocation process is stopped, and the base site continues scanning for channel request signals.

    摘要: A method and apparatus is used for transmitting an outbound message in a two-way messaging system having a plurality of cells employing frequency reuse. The outbound message is transmitted to a selective call transceiver (122) utilizing a first frequency reuse plan (312). The two-way messaging system awaits a positive acknowledgment (316, 318) from the selective call transceiver (122) confirming that the outbound message was received with an acceptable quality. The two-way messaging system retransmits the outbound message to the selective call transceiver (122) utilizing a second frequency reuse plan (332), in response to receiving a negative acknowledgment and also in response to failing to receive any acknowledgment within a predetermined time after transmitting the outbound message.

    摘要: A method and apparatus completes inbound calls for portable communication units (120) in a wireless communication system comprising portable communication units (120) and fixed communication units (102). The fixed communication unit (102) provides wireless communications over a limited coverage area (108, 110, 112) and provides coupling to a telephone system (114). The fixed communication unit (102) has at least one wireless transmission channel carrying call set-up signaling in a first mode and user communications in a second mode. The method includes in the fixed communication unit (102) the step of generating (708) more than one sequence of periodic call set-up polls on a wireless transmission channel for polling a portable communication unit (120) having an inbound call. The sequence coexists with other sequences of periodic call set-up polls being generated concurrently on the same wireless transmission channel.

    摘要: A TDMA communication system (100) comprises a two-way subscriber unit (112') and at least two base stations (104b and 104c). The subscriber unit monitors the strengths of signals (114') received from the base stations. As the subscriber unit roams within the area serviced by the communication system, the received signal strength will vary as the subscriber unit moves nearer to or farther from the base station that is transmitting the call. When the subscriber unit moves out of the range of the base station, the subscriber unit determines, based on certain predetermined criteria, with which base station to communicate.
