Abstract

Informing a number of users about an emergency or other situation of public interest is accomplished using a broadcast service. A specific identifier is used in a paging message for activating broadcast service in terminals. A terminal checks a received paging message with regard to the presence of the specific identifier and when detecting the specific identifier, switches to a broadcast mode for receiving broadcast content. The received broadcast emergency content is notified and/or displayed to the users of the terminals.

Claims

1-10. -10. (canceled)

11. A method of communicating with a terminal, comprising:

storing, at the terminal, a predefined specific identifier common to all terminals supporting an emergency warning;

checking, by the terminal, whether a received paging message includes the specific identifier; and

switching directly, by the terminal, to a broadcast mode for receiving broadcast content upon detection of the specific identifier.

12. A method according to claim 11, wherein the terminal is a mobile terminal attached to a mobile network, and the broadcast mode is a Global System for Mobile Communications cell-broadcast mode.

13. A method according to claim 12, wherein the terminal at least one of notifies and displays received broadcast content to a user of the terminal.

14. A method according to claim 13,

wherein said storing includes storing several specific identifiers, and

wherein said switching is performed differently by the terminal switching to the broadcast mode for an infinite time, or only for a limited duration, or only when the terminal is assigned to a group specified by one of the specific identifiers, depending on which of the specific identifiers is detected by said checking.

15. A method according to claim 14, wherein the specific identifier is a temporary subscriber mobile identity and is assigned to and stored in several terminals.

16. A terminal operating in a communication system having a plurality of terminals, comprising:

storage means for storing a predefined specific identifier common to all of the terminals supporting an emergency warning;

checking means for checking whether a received paging message includes the specific identifier; and

switch means for switching directly to a broadcast mode for receiving broadcast content upon detection of the specific identifier.

17. A terminal according to claim 16, wherein the terminal is a mobile terminal, the communication system includes a mobile network via which the mobile terminal communicates, and the broadcast mode is a Global System for Mobile Communications cell-broadcast mode.

18. A terminal according to claim 17, further comprising at least one of

acoustical means for notifying received content to a user of the terminal;

and

display means for displaying received content to a user of the terminal.

19. A terminal according to claim 18,

wherein said storage means stores several specific identifiers, and

wherein said switch means reacts differently by switching to the broadcast mode for an infinite time, or only for a limited duration, or only when the terminal is assigned to a group specified by one or the specific identifiers, depending on which of the specific identifiers is detected by said checking means.

20. A network communicating with terminals and adapted to implement a cell broadcast service and a paging mode, comprising:

a transmitter broadcasting content and transmitting at least one paging message to all of the terminals in a cell, the at least one paging message including a predefined specific identifier for directly switching, upon detection of the specific identifier, the terminals receiving the paging message to a broadcast support mode for receiving the broadcast content.
