摘要： A cellular radiotelephone system (101) includes a control terminal (420) coupled by in trunks and out trunks to the telephone central office (110) and by data and voice lines to base sites (411-416) in corresponding cells (401-406) for providing telephone coverage to mobiles located throughout a geographical area. In order accommodate additional voice channels in each cell (401-405), base sites (441-446) are colocated with corresponding existing base sites (401-405). Paging/access channels are assigned to existing base sites (411-416) for paging mobiles for all outgoing originations and processing all incoming mobile originations and page responses. Access-only channels are assigned to colocated base sites (441-446) for processing mobile originations and page responses transferred thereto by a directed retry message from corresponding existing base sites (401-405). The additional voice channels assigned to colocated base sites (441-446) may be voice channels in new radio frequency bands allocated to cellular radiotelephone systems. If both existing and additional voice channels are assigned to existing base sites (411-416) and/or colocated base sites (441-446), new voice channels are assigned to requesting mobiles before assigning existing voice channels, provided that the requesting mobile operates on both existing and new voice channels.

摘要： A cellular radiotelephone system providing service to remote units having a voice operated transmitter (VOX) is disclosed. If the regularly scheduled periodic signal quality measurements made by fixed site equipment indicate that the remote unit signal has not been received for a predetermined number of measurements, an audit request is transmitted to the remote unit. The remote unit responsively keys its transmitter for a predetermined period of time. A first special scan is programmed into the regular process such that the fixed site equipment may continue with its regular process until the signal quality measurement must be made. A second measurement is made following the first and if the two signal quality measurements made while the VOX remote unit is known to be transmitting agree, system reconfiguration for the service of this remote unit may be implemented by the cellular system.

摘要： A two way radio system employing power control of a remote station transmitter to produce a predetermined received signal level at a fixed site after handoff of the remote station from one radio channel to another is disclosed. A signal strength measurement is made on the in-use channel and a power level for the remote station transmitter is calculated from the measured signal strength, a predetermined nominal signal strength desired on the target radio channel, and a linear correlation of signal strength and remote station power level steps. The calculated remote station power level is then transmitted to the remote station as part of a handoff command.

摘要： A data message transmission system for a cellular radiotelephone system is disclosed. Data to be transmitted is converted into a format compatible with radio transmission prior to transmission. The data is reconverted to its original format following reception. Handoff is accomplished by halting the data transmission prior to handoff and resuming data transmission after handoff. Call supervision occurs via busy-idle bit coding.
