<p>In a system of multiple radiotelephones, such as mobile telephones, wherein each of the telephones is operative with a paging channel by which a calling number is applied to the telephones enabling the respective telephones to respond to their respective channels, the paging channel is utilized for activating individual ones of the telephones. A set of calling numbers is reserved and not employed for calling numbers, but is stored within a memory of each of the telephones. The reserved calling numbers serve as a glossary for encoding words of a command message to be transmitted via the paging channel, and also enable a decoding at each telephone of the encoded message. The command message supplies a designated calling number to a specified one of the mobile telephones, the specified telephone being identified by its electronic serial number. <IMAGE></p> |
