Abstract: A satellite based paging communication system comprises a plurality of terrestrial stations capable of communicating the paging information with at least one satellite. The satellite(s), in turn, are capable of communicating the paging information to at least one terrestrial receiver or terrestrial station. Also included is at least one control station for determining where and how to deliver the paging information to one or more of a plurality of terrestrial receivers (pagers), at least some of which are capable of receiving the paging information from one or more of the satellites and one or more of the terrestrial stations.

Abstract: A communication system has an information signal having a plurality of data streams. The data streams are simultaneously modulated on a multi-level symbol transmission. The data streams may have either independent or dependent signalling protocols. A transmitting device generates the information in one of several embodiments. A first receiver receives the information signal and process only a first data stream for messages. A second receiver receives the information signal and process only the second data stream for meassages. A third receiver is capable of selectively receiving and processing a plurality of data streams. The third receiver is shown in several embodiments for selecting the data streams.

Abstract: An ideographical character signalling system (2), such as an ideographical character paging system, comprising input means (4) for inputting a plurality of first and second different types of ideographical characters, said input means including coding means (84) for coding both said first and second types of ideographical characters according to a first code, and signal processing means (10) for receiving a data signal comprising said first and second types of ideographical characters coded according to said first code, said signal processing means comprising code converting means (88) for selectively coding the coded first type of ideographical characters according to a second standard code. A signal receiver (34), for receiving data signal comprising a plurality of coded ideographical characters, and having character generating means (52) for generating for display only the most frequently used ideographical characters together with a special character symbol if a rarely used character is received, is also disclosed.

Abstract: A paging system has a signal for transmitting a variable amount of messages to paging receivers. The signal has a synchronization signal (100), an address field (104), an information and a boundary signal indicative of the boundary between the address field and the information field. Each message has an address which is included within the address field and may have message information which is included in the information field. The information field includes two portions, a first portion (106) having a plurality of packets for holding a predetermined amount of information and a second portion (108) for holding a variable amount of information. If the message information is greater than the predetermined amount, it is stored in the second portion of information field and a vector signal indicating the location of the message information is stored in the first information field.

Abstract: A selective call receiver receives a signal having a baud rate and comprising a number of phases. The number of phases are time division multiplexed to form the signal. The selective call receiver has selective call address information assigned thereto and includes a receiver for receiving and demodulating the signal and a memory for storing predetermined information. A demultiplexer is coupled to the receiver and the memory for demultiplexing the signal to recover one of the number of phases in response to the predetermined information and the baud rate. The selective call receiver also includes a decoder coupled to the demultiplexing means for decoding said one of said number of phases of said signal to derive a selective call message therefrom.
