Abstract:
A message transmission system comprising a primary station configured for transmitting point-to-point messages over a communications link and a plurality of secondary stations, each secondary station being configured for receiving messages from the primary station directed to the secondary station via the communications link, and having means for recovering the received messages and non-volatile memory means for storing n (where n is an integer) items of information most frequently used in the messages directed to the secondary station, each item of information being identifiable in a received message by memory location reference indicia appearing in place of the item, the primary station having storage means for storing for each secondary station, said n items of information most frequently used in messages directed to the secondary station, and their associated memory location reference indicia, the primary station being configured for, whenever appropriate, transmitting memory location reference indicia to the secondary station in place of an item of information which is one of the presently stored n items of information most frequently used in messages directed to the secondary station, the primary station having means for dynamically determining for each secondary station the n items of information most frequently used in the messages directed to the secondary station, and if any of the currently determined n items of information most frequently used in the messages directed to the secondary station is different from the presently stored n items of information most frequently used in the messages directed to the secondary station, forming and transmitting a programming/reprogramming message directed to the secondary station for updating the items of information stored in the memory means of the secondary station, and correspondingly updating the items of information stored in its storage means relating to the secondary station.
