In the transmission of a message (LU) from a subscriber station (MS), a cell recognition signal (e.g. CI2) identifying the current radio cell (e.g. C2) in which the subscriber station (MS) is located is transmitted towards the mobile radio system with it and stored in a subscriber database (NVLR) of the mobile radio system. The stored cell recognition signal (e.g. CI2) makes it possible to call the subscriber station (MS) via a radio message to the most recently used radio cell(s) (e.g. C2) and possibly also to its/their neighboring radio cells. This reduces the signaling load on the transmission of the radio message (effective paging) in the area where there are radio cells. It is possible to derive the location information on the radio cell plane, which consists of the cell recognition to identify the radio cell last used by the subscriber station, without any additional signaling load.
A method for sending a radio paging broadcast to radiotelephone subscriber stations of mobile radiotelephone subscribers of a cellularly constructed mobile radiotelephone network, comprising the steps of:
A system for transmitting a radio paging broadcast to radiotelephone subscriber stations of mobile radiotelephone subscribers in location areas of a cellularly constructed mobile radiotelephone network, whereby the location areas respectively manage locations of the radiotelephone subscriber stations, and respectively consist of at least one radio cell, and are identifiable by a location area identifier, comprising:
