Abstract: A base site (100) employs a method and apparatus for selecting two of a plurality of antennas (101-106) from which to receive a communication signal. A first signal quality metric is measured for a communication signal received from a first antenna (102) and a second signal quality metric is measured for the communication signal received from a second antenna (103). When the first signal quality metric differs from the second signal quality metric by a threshold, a signal receiver (113) is coupled to a third antenna (e.g., 101) and a third signal quality metric is measured for the communication signal received from the third antenna (101). Based on the three signal quality metrics, a primary antenna and a secondary antenna are selected from which to receive the communication signal.

Abstract: In a wireless communication system, including a first fixed communication unit (105), a plurality of other fixed communication units (101, 106), and a mobile communication unit (103) responsive to at least the first fixed communication unit, a radio telephone service planning method for generating a handover neighbor list. The method includes determining a route of travel of the mobile communication unit (103) relative to the first fixed communication unit (105). The method also includes establishing a plurality of connections between the mobile communication unit (103) and the plurality of other fixed communication units, based on the route of travel of the mobile communication unit, and then determining a corresponding plurality of signal quality metrics for the plurality of connections. The method further includes generating a handover neighbor list based on the corresponding signal quality metrics.

Abstract: A method of maintaining call quality in a communication system by communicating between a base site (101) and a communication unit (113) on a first channel. The communication unit (113) monitors the downlink communication signal (116) transmitted by the base site (101) and determines a characteristic of the first channel. The communication unit (113) is then handed off to a second channel having a less aggressive reuse pattern, based on the characteristic of the first channel.

Abstract: A radiotelephone service planning system (10) and method determines best servers in communication systems by determining a interference based communication threshold using interference information (46), such as frame error rate data, in addition to pathloss information (38) between a communication unit (22) and the plurality of other communication units (24a-24c). The radiotelephone service planning system (10) and method generates an image indicating the most probable best server of the other communication units (24a-24c) for the communication unit (22) based on the interference based communication threshold information. Also, the system utilizes variable signal threshold data (32) for a communication unit to allow flexibility in determining a best server site in view of varying threshold limits. If desired, the system can also accommodate three-dimensional best server planning by taking into account elevational variations and their effects from the perspective of both the mobile communication unit and the other communication unit.

Abstract: A method improves the decoding rate and reliability of adjacent cell base stations by expediting the decode process if the signal quality of a traffic channel is within a predetermined range. In particular, adjacent control channels are monitored and decoded at a rapid rate by ignoring the speech traffic channel information. The speech is interrupted (526) and the channel information is decoded (526) when, for example, the bit error rate or frame error rate of the traffic channel (TCH) is deteriorating while another channel has a better signal. The scheduling of speech channel interruptions (522) may also occur when insufficient neighbor cell information is available at the beginning of a call or immediately after handover. The lost speech signal could be recovered (536) using conventional speech extrapolation techniques.

Abstract: Un método que mejora la velocidad de decodificacion y confiabilidad de las estaciones base de células adyacentes al facilitar el proceso de decodificacion si la calidad de la señal de un canal de tráfico se encuentra dentro de un rasgo predeterminado. En particular, los canales de control adyacentes se monitorean y decodifican a una velocidad rápida al ignorar la informacion del canal de tráfico de voz. La voz interrumpe (526) y la informacion del canal se decodifica (526), por ejemplo, la proporcion de error de bit o la proporcion de error de la configuracion del canal de tráfico (TCH) es deteriorante mientras otro canal tiene una mejor señal. La programacion de las interrupciones del canal de voz (522) pueden también ocurrir cuando la informacion disponible de las células vecinas es insuficiente al inicio de una llamada o inmediatamente después de la transferencia. La señal de voz perdida puede ser recuperada (536) utilizando técnicas de extrapolacion de voz convencionales.
