Abstract

The following describes a technology to allow groups of pagers to have their time updated from a system. A pager's time is used to timestamp incoming messages. This time is set by the user, and as such, is subject to errored entry. Furthermore, the time could be lost due to pager internal clock inaccuracies as well as the pager losing power due to a low battery. What we describe is a manner of updating pager's clocks at any time using the system. Each update needs to be sent only once and should access all pagers on a system, yet not require the pagers to have a common paging address. This particu- lar method works within a POCSAG standard, and uti- lizes combinations of sync codes (which all pagers exam- ine), to modify a pager group's clocks.
