    摘要: A pager based information system (2) is used to transmit both conventional individual and group messages (using pager capcodes (76) for pager identification) and three types of unconventional multi-recipient (M-R) messages (using database ID's (68), multi-level group (MLG) ID's (78) and M-R group ID's (46)), all using the conventional POCSAG pager transmission format. Operation of the pager (6) is software controlled through the use of a microprocessor (8) and RAM (16); auxiliary chips are not needed because of the relatively slow transmission speeds. Authority to receive the M-R messages is provided at the time of manufacture (electronic serial number (ESN) (74)) or via broadcast (database ID's, MLG ID's and group IDs). Database messages are stored in pager RAM in a hierarchical or tree structure. The software controlled pagers permit the over-the-air modification of the operation of selected pagers, such as the addition or deletion of group IDs and the change in the tree structure of the database area of RAM (typically through the transmission of database messages). The pager includes a real time pager clock (106) which is updated by pairs of broadcast time messages, the second having a time correction for the first.

    摘要: Un récepteur (11) sélectif d'appels comprend un récepteur (13) destiné à recevoir un signal, le signal comprenant une adresse identifiant le récepteur sélectif d'appels, un premier paquet d'informations ayant un premier format d'informations, un second paquet d'informations ayant un second format d'informations, ainsi qu'un caractère de commande. Un dispositif de sortie (17) présente le premier paquet d'informations dans un premier mode de sortie correspondant au premier format d'informations, en réponse au caractère de commande, et le second paquet d'informations dans un second mode de sortie correspondant au second format d'informations, en réponse à l'adresse ou à un second caractère de commande.

    摘要: A paging receiver is disclosed which is compatible with transmissions from analog or digital paging transmitters. The paging receiver has a command structure which permits it to be dynamically programmable to change its functionality including programming of the channels which the paging receiver is to receive. The programmability of the channels permits the paging receiver to be used for making national, regional, remote area, local area, and sublocal area pages, and pages to a group in the local area and to switch from channels which are heavily used during peak paging times to lesser used channels. The paging receiver transmits the paging receiver identification code digits in an order of increasing significance which significantly lessens power consumption for all paging receivers tuned to a particular frequency for determining if a page is to be received which prolongs paging receiver battery life. The paging receiver displays the place of origin of pages as either being of local origin or from other areas. The paging receiver antenna is continuously tunable to permit compensation for variation in antenna gain caused by environmental factors which can seriously degrade signal strength.

    摘要: A paging receiver with a display function allows a usual message to be displayed and a receiver control signal to be sent together in a single message format. A first and a second predetermined character are detected in a received message, and a message occurring between the first and second characters is extracted as a receiver control signal and not displayed on a display.
