PAGER BASED INFORMATION SYSTEM

阅读:175发布:2021-11-04

专利汇可以提供PAGER BASED INFORMATION SYSTEM专利检索,专利查询,专利分析的服务。并且A pager (6) based information system is used to transmit both conventional private messages (using unique pager IDs) and two types of unconventional multirecipient (M-R) messages (using database IDs and group IDs), all using the conventional POCSAG pager transmission format. Operation of the pager is software controlled (Figs. 9A-9E) through the use of a microprocessor (8) and a 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 (database IDs) or via broadcasts (group IDs). Database type M-R messages are stored in the pager RAM (16) 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 (Fig. 7) and the change in the tree structure of the storage area for the database messages. The pager (6) includes a real time pager clock (56) which is updated by pairs of broadcast time messages (Fig. 9E), the second having a time correction for the first.,下面是PAGER BASED INFORMATION SYSTEM专利的具体信息内容。
