    摘要: A radio telephone communication system (200) having a base station (203) including at least one frequency agile time division duplex transceiver (207) for facilitating communication with at lest one radio telephone (100) on the at least one radio frequency channel. The radio telephone (100) scans a plurality of channels capable of being generated by the at least one frequency agile transceiver (207) to find an available channel and provide an indication representing a base station busy status when all the at least one frequency agile transceivers are in use. A base station busy status is indicated when one of a bidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver or a unidirectional time division duplex communication including a base station identification signal is being communicated by the at least one frequency agile transceiver (207).

    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: Calls entered into a paging system are processed by a controller which identifies the call source from which the call originates, and from a table of predetermined call sources the controller generates a source tag identifying the call source. The source tag is transmitted together with any caller generated message to a paging receiver. The paging receiver, upon receiving the source tag, selects a predetermined message from a table of predetermined messages, and displays the predetermined message stored within and displays the predetermined message together with the caller generated message. The tables of predetermined call sources and predetermined messages are definable by the paging receiver user.

    摘要: A selective call control center is provided for transmission of calls to selective call receivers, such as paging receivers. In a first aspect, priorities are assigned to call sources and to call receivers and the order of transmission of calls is determined by the control center as a function of the priorities of the source and the receiver for each call. In a second aspect, at least one call receiver is provided having at least two addresses and the address to be selected from the at least two addresses for calling that receiver is determined dependent on the priority of the source of the call.

    摘要: In a radio telephone (100, 200) having a keypad (206) for receiving first information (302), a memory (112) for storing second information (313), and an intelligent editing function. There is provided a method of transmitting information representing a phone number using the intelligent editing function that selects a prefix mode when a phone number has been automatically entered and selects an appending edit mode when the information representing a phone number has been manually entered. The information is then edited to form a complete phone number (315), and transmitted (102, 104, 105, 106).

    摘要: A communication system base site (300) receives a signal (400) representing a request from a communication unit (200) to access the communication system (100). The signal includes an identification code (402) and another code which represents when the communication unit was authorized to access the communication system (410). The base site (300) operates to process the identification code (402) to initially determine that the communication unit (200) should not be permitted access to the communication system (100). Additionally, the other code (410) is processed to determine whether the communication unit (200) was authorized to access the communication system (100) within a time interval. If so, the communication unit (200) is permitted to access the communication system.

    摘要: A central controller operating as a pager terminal for receiving, handling, and transmitting messages is shown that adaptively alters its message handling characteristics in order to improve the overall throughput of the central controller. The channel loading characteristics, based upon the time of day, are used in order to vary the limitation of the size of message received by the central controller as well as vary the transmission size and age of messages prior to transmission. Additionally, channel loading may be determined by determining the total size of messages within the central controller. In response to the total size determination, the limitation of the message size received by the controller may be varied. Furthermore, the transmission size and age of messages prior to transmission may be varied in response to the total size determination. The central controller may also adopt these operations in response to the combination of the total size determination and channel loading based upon the time of day characteristics.

    摘要: An improved simulcast transmission system having automatic synchronization is disclosed which utilizes a signal from any one of a number of readily available master timing sources to maintain a constant, uniform time delay to a multiplicity of transmitters even though the time delay corresponding to an included individual interconnect link is susceptible to variation. This simulcast system includes a central controller for controlling, via an interconnect link, the operation of each transmitter located at a plurality of base station sites. This central controller includes a master timing signal receiver and periodically outputs a resynchronization command via the interconnect link to the base stations. Each interconnect link may consist of a phone line or other radio link which exhibits a relatively fixed, but unstable, delay. Each base station includes at least a transmitter and an adaptive-delay device which operates as a remotely-adjustable delay network upon receipt of a resync signal from the central controller to readjust and automatically maintain a uniform amount of time delay to each transmitter in the base stations. A master timing signal receiver such as a suitable radio navigation receiver is coupled to a suitable fixed delay network and provides the reference sync signal for each remotely-sited base station throughout the designated geographical area. This simulcast system is therefore cable to compensate for varying amounts of delay caused by utilizing alternate links which may be necessary to maintain system reliability while overcoming inclement weather, interference, or other equipment difficulties.
