Abstract: 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.

Abstract: A communication system is described which provides call queueing between a base station (400) which does not have a control channel and a plurality of portable communication handsets (401). The base station (400) determines when all channels are busy, and following one becoming available, transmits a first predetermined code. All portable communication handsets (401) which attempted to communicate with the base station (400) when all channels were busy, sets a queue mode flag, and starts a timer (455, 461). When a first predetermined code is detected by any handset (401) having attempted to establish communication with the base station (400), the first timer (455, 461) continues, and a second timer (455, 461) operating at a second rate is started at the value established by the first timer (455, 461). When the second timer (455, 461) value reaches a predetermined value, the handset (401) proceeds to attempt to establish communication with the base station (400) on the channel that became available.

Abstract: A communication system (100) has at least one base site (204) which includes a plurality of transceivers (110A-C) operating on a plurality of communication channels for communicating to at least one of a plurality of communicators (108). The at least one base site (204) comprises a generator (210) generating a plurality of interference signals according to a predetermined pattern on a subset of the plurality of communication channels. A processor (208) initiating and terminating communication between the base site (204) and the at least one communicator (108) on a selected communication channel substantially free of interference signals. The processor (208) further determines the communication channel being selected, and determines whether to change the predetermined pattern of the plurality of interference signals.

Abstract: Communication between first (38, 40 or 42) and second (38, 40 or 42) portable radiotelephone transceivers is provided in a radiotelephone communication system by generating a paging message (500-512) in response to the first transceiver (38, 40 or 42) registering with a first telepoint base station (32, 34 or 36). The paging message (500-512) is directed to the second transceiver (38, 40 or 42) for which communication is requested, and identifies the first telepoint base station (32, 34 or 36) and the first transceiver (38, 40 or 42). Upon receiving the paging message (500-512), the second transceiver (38, 40 or 42) registers with a second telepoint base station (32, 34 or 36), downloading the information identifying the first telepoint base station (32, 34 or 36) and the first transceiver (38, 40 or 42).

Abstract: 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.
