Abstract: A selective call receiver comprises a receiver for receiving a signal, the signal comprising an address identifying the selective call receiver, a first information packet having a first information format, a second information packet having a second information format, and a control character. An output device presents the first information packet in a first output mode corresponding to the first information format in response to the control character, and the second information packet in a second output mode corresponding to the second information format in response to the address or a second control character.

Abstract: A data communication receiver (106) providing burst error protected data synchronization comprises a receiver portion (804) for receiving and detecting synchronization data and message information. The synchronization data comprises at least first and second synchronization code words separated by a predetermined transmission time interval. A synchronization correlator (818, 1310 or 1330) correlates for the first synchronization code word, and in the absence of correlating the first synchronization code word, correlates for the second synchronization code word, thereby insuring synchronization with the received message information.

Abstract: A subscriber's PMU (Personal Messaging Unit) (14) determines when the number of incoming messages is likely to be excessive by counting the incoming messages and comparing their number and rate of receipt to stored thresholds. The subscriber is alerted when an excess is detected, and he is given options such as: routing future messages to himself via alternate and less expensive communications links (34, 38), or terminating messages sent to one of his PMU's addresses that has been receiving messages at a high rate. Similar control can be effected at the PMU's base station (12).

Abstract: A paging signalling system communicates messages via a synchronous signal. The s ynchronous signal is divided into a plurality of frames (100) in which selective groups of pagers decode. A signal ( 102) within the frame (100) causes groups of pagers to decode in various frame (104, 106), wherein several groups of pagers may be comb ined into a signal frame to decode messages (110). Embodiments of the invention include first type of a plurality of groups of pagers, each group having a common maximum frame rate, a second type of a single group of pagers having a unique maximum fr ame rate, and a third type of a single group of pagers having no maximum frame rate. The three types of groups may decode the sy nchronous signal.

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 communication receiver (10) including a display (22) having a predetermined number of displayable characters, a decoder (14) for receiving and processing data messages, a plurality of control switches (20) for operating the decoder (14), and a memory (16) for storing a plurality of received data messages. The decoder (14) selects a data message to display from the memory (16), arranges the data message into a plurality of screens, computes an individual variable screen timeout value for each screen, and displays each screen on the display (22) in a predetermined order for the screen timeout value computed. The screen timeout value is computed on the basis of the message content of the screen, the presence of control characters in the data message, or the generation of input signals from the control switches (20). The screens can be displayed in a forward direction or a reverse direction. Each direction can either be at a fast or a slow rate.

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: A paging receiver has an indicator capable of illluminating in one of a plurality of colors. The color of illumination is selected in response to the address received by the pager. The indicator identifies the address by the color illuminated. The indicator also indicates weather a message is protected, read, about to be protected or about to be deleted by the color and color sequence of the indicator. The color indicator also indicates if the paging receiver is about to be turned off. The indicator may also serve as a back-light for a display when the paging receiver includes a display. Signals within the information to be displayed may change the color or change the intensity of the back-light, these signals may also turn the back-light off or on.
