Pager operating method for e.g. alarming function, involves switching pager during detection of preamble of paging signal of paging network based on reception of paging signal, where paging signal is transmitted with high strength

摘要

The method involves allowing a pager (P) to enter into a search mode for detection of a preamble of a paging signal of a paging network (1) during reception of a paging signal of a paging network (2). The paging signal of the network (1) is transmitted with high signal strength than the paging signal of the network (2). The pager is switched during detection of the preamble of the paging signal of the paging network (1) based on the reception of the paging signal of the paging network (1). A message from the pager is classified as security relevant when a batch contains the same message twice.
