  • system 20 operates by a message being sent at step 30 to information centre 21.
  • This message is sent, for example, by a conventional trunk call.
  • the message is then processed at step 31 by information centre 21 and coded into an appropriate data protocol .
  • step 32 the character length of the message is checked at step 32. If the length is greater than thirty characters, including spaces, then step 33 sets a message type bit associated with the data protocol to logic 1. At step 34 only the first thirty characters of the message are selected to be transmitted as a preview message of a longer message.
  • the longer message and an identifier address code are stored in memory, for example, at information centre 21. If at step 32 the character length of the message is found to be less than thirty characters, then the message type bit is set to logic 0. This identifies the message as a non-preview message and at step 36 the message and an identifier address code are then stored in memory.
  • the above processing steps 31 to 37 are performed at information centre 21.
  • the preview message (or non-preview message) , including the message type bit and identifier address code, are then modulated at information centre 21 and then transmitted by antennas 22 to selective call receiver 1.
  • antenna 7 receives the message including the message type bit and identifier address code which is amplified by amplifier 9, filtered by transceiver 8 and demodulated by demodulator 10.
  • decoder 11 in combination with associated with Read Only Memory 12 decodes the message protocol.
  • the decoded message including the message type bit and identifier address code are stored in Random Access Memory 4 at step 41.
  • the message type bit is then checked at step 42. If the message type bit set to logic 1 then it is determined that the message is a preview message.
  • the liquid crystal display 5 then displays the preview message along with an icon identifying the message as a preview message of a longer message.
  • step 42 if at step 42 if the message type bit is found to be a logic 0 then it is determined that the message is a non-preview message. Accordingly, at step 44 the non-preview message is displayed by the liquid crystal display 5. Further, speaker 16 and motor 17, if switched to active mode, signal at either steps 43 or 44 that a message has been received.
  • step 45 an appropriate key is activated on keypad 6 to generate a longer message request signal.
  • the longer message request signal and the identifier address code are sent to decoder 11.
  • the longer message request signal and address code are coded into a pager request code at step 46 which is modulated by modulator 10 filtered by transceiver 8 amplified by amplifier 9.
  • the pager request code is then transmitted by transmitter 7 at step 47 and received by one of antennas 22 at step 48.
  • the pager request code is then sent to information centre 21 where the request code is amplified, filtered, demodulated, decoded.
  • the identifier address code of the longer message is then used to access the stored longer message.
  • the longer message is then transmitted, by one of antennas 22, to selective call receiver 1 at step 49.
  • the longer message has its associated message type bit set to 0 and therefore selective call receiver 1 treats the message as a longer message.
  • the present invention advantageously reduces or at least alleviates at least one of the problems associated with transmitting relatively long messages to selective call receivers.
  • pager users can select whether or not they wish to view longer messages associated with a preview message. This can result in more efficient usage of communication channels, wherein the selective call receiver user has the option of requesting specific long paged messages upon receipt of a preview message.
  • the present invention may advantageously reduce the running costs and overheads associated with transmitted pager traffic. Further, the present invention allows for economical common preview messages being sent to numerous pagers, wherein only users interested in the preview message can request the full longer message. Such preview messages may include weather forecasts, news flashes or stock market data.

Abstract

Récepteur d'appel sélectif bidirectionnel (1) comportant un circuit émetteur et récepteur combiné (2) pour la réception d'un message transmis codé, et un processeur (3) servant à déterminer si le message est un message de précontrôle d'un message plus long. Le récepteur d'appel sélectif (1) comporte également une mémoire (4), un afficheur (5) et un clavier (6). Lors de la réception d'un signal en provenance du clavier (6), le processeur (3) envoie un signal de demande codé au circuit émetteur et récepteur. Ce signal de demande est utilisé pour solliciter, auprès d'un système d'information, le message plus long associé au message de précontrôle.
