Method of transmitting urgent alarm messages to mobile terminals being located in cells of a mobile communication network and a correponding network controller

摘要

The method involves generating, in an alert center (CA), a short message system-cell broadcast service (SMS-CB) type message associated to a chosen alert class of a chosen level and containing an alert text message intended to mobile terminals (T11, T12, T21, T22, T31, T41, T51) located in a chosen cell. A radio access network interrupts transmission, to the terminals, of the SMS-CB type message associated to a class of level lower than that of the chosen level. An alert signal is emitted and the text message is displayed at the terminals that have received the SMS-CB type message. Independent claims are also included for the following: (1) a radio network controller for a radio access network of a radio communication network (2) an alert center.
