Abstract: A paging system which provides both individual and information services includes a transmitter for transmitting page call address and data periodically in batches, and a population of battery saver paging receivers for receiving the transmitted call information. Each transmission batch comprises a synchronization code followed by a predetermined plurality of sequential frames. Each subscribing receiver searches for its individual service address in a first designated frame of each batch of a transmission period, and in addition, searches for its information service address in a second designated frame of a designated batch of a transmission period. Individual and information service data messages are obtained from frames subsequent the frame at which their respective address is found.

Abstract: A radio communication system (5) includes a transmitting unit (1) coupled to at least one controller (6). The controller (6) is adapted to subdivide the SCR's (selective call receivers) (2) into SCR groups, assign the SCR groups to supergroups, and assign a selected number of message frames (216) and message intervals (208) to each SCR group in each supergroup. A supergroup is then selected, and included in an acquisition group message. The supergroup is for directing SCR's (2) targeted to receive the acquisition group message to monitor messages during the message reception interval (203) according to the supergroup. The controller (6) then invokes the transmitting unit (1) to transmit the acquisition group message to the SCR's (2). Messages target for specific SCR's (2) are then generated, and transmitted by way of the transmitting unit (1) according to the supergroup selected. The targeted SCR's (2) receive the messages according to the supergroup received.

Abstract: A paging system which provides both individual and information services includes a transmitter (2) which transmits page call address and data periodically in batches to subscribing paging receivers (4). Each batch comprising a synchronization code followed by a predetermined plurality of sequential frames. Each paging receiver (4) searches for both its individual service address and a first information service address in its corresponding assigned frame of each batch of a transmission period, and in response to reception of the first information service address, searches for a second information service address in a designated common frame of each batch of a transmission period. Individual and information service data messages are obtained from frames immediately subsequent the frame in which the respective individual and second information service addresses are found.

Abstract: In a battery powered selective call receiver receiving a synchronous signal (100), a battery saving method extends battery life by optimizing the amount of time (124, 128) the receiver circuit is activated when searching for reception of a predetermined code (134) after previously (104) acquiring synchronization with the signal.

Abstract: ysstème de recherche de personnes offrant à la fois des services 6164onnalisés et d'information, comprenant un transmetteur (2) qui transmet périodiquement des données et des adresses d'appel de recherche sous forme de lots aux récepteurs (4) abonnés à un système de recherche de personnes. Chaque lot comporte un code de synchronisation suivi d'une pluralité prédéterminée de blocs séquentiels. Chaque récepteur de poche (4) recherche à la fois sa propre adresse de service personnalisé une première adresse de service d'information dans le bloc affecté lui correspondant, appartenant à chaque lot pendant une période de transmission, et en réponse à la réception de la première adresse de service d'information, le récepteur de poche recherche une deuxième adresse de service d'information dans un bloc spécifique commun de chaque lot pendant une période de transmission. Les messages personnels et les messages contenant données d'un service d'information sont extraits des blocs suivant immédiatement le bloc dans lequel se trouvent respectivement l'adresse de service personnalisé et la deuxième adresse de service d'information.
