Abstract
Abstract A pager based information system is used to transmit both conventional private messages (using unique pager IDs) and two types of unconventional multi-recipient (M-R) messages (using database IDs and group IDs), all using the conventional POCSAG pager transmission format. Operation of the pager is software controlled through the use of a microprocessor and a RAM; 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 (database IDs) or via broadcasts (group IDs). Database type M-R messages are stored in the pager RAM in a hierarchial 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 storage area for the database messages. The pager includes a real time pager clock which is update by pairs of broadcast time messages, the second having a time correction for the first.
