Abstract

The invention relates to a method, terminal and network or entity wherein a broadcast service is used for informing a number of users on an emergency or other situation of public interest. A specific identifier is used in a paging message for activating broadcast service in the 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. (canceled)

2. A method of communicating in a bi-directional cellular wireless communication system between a base station and a plurality of mobile terminals supporting an emergency warning, the method comprising:

storing, at a mobile terminal of the plurality of mobile terminals, at least two specific identifiers common to the plurality of mobile terminals, the at least two specific identifiers being for different types of emergencies;

checking, by the mobile terminal, whether a paging message received from the base station includes at least one specific identifier of the at least two specific identifiers;

switching, by the mobile terminal, to a broadcast mode for receiving broadcast content on a broadcast channel when the received paging message includes the at least one specific identifier of the at least two specific identifiers; and

establishing, by the mobile terminal, at least one of a physical channel and a logical channel when the received paging message includes a mobile terminal identifier allocated to the mobile terminal.

3. The method of claim 2, wherein the mobile terminal identifier is at least one of a temporary mobile subscriber identity, an international mobile subscriber identify, and a packet temporary mobile subscriber identity.

4. The method of claim 2, wherein the broadcast mode is a GSM cell-broadcast mode.

5. The method of claim 2, wherein the mobile terminal notifies and/or displays to a user of the mobile terminal the broadcast content.

6. The method of claim 2, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the at least two specific identifiers.

7. The method of claim 6, wherein the duration of the broadcast mode is for an indefinite length of time or for a limited duration of time based on the at least one specific identifier of the at least two specific identifiers.

8. A mobile terminal configured for operating in a bi-directional cellular wireless communication system having a base station and a plurality of other mobile terminals supporting an emergency warning, the mobile terminal comprising:

a memory unit configured to store at least two specific identifiers common to the plurality of other mobile terminals, the at least two specific identifiers being for different types of emergencies; and

a control unit configured to;

check whether a paging message received from the base station includes at least one specific identifier of the at least two specific identifiers;

switch to a broadcast mode for receiving broadcast content on a broadcast channel when the paging message received from the base station includes the at least one specific identifier of the at least two specific identifiers; and

establish at least one of a physical channel and a logical channel when the received paging message includes a mobile terminal identifier allocated to the mobile terminal.

9. The mobile terminal of claim 8, wherein the mobile terminal identifier is at least one of a temporary mobile subscriber identity, an international mobile subscriber identify, and a packet temporary mobile subscriber identity.

10. The mobile terminal of claim 8, wherein the broadcast mode is a GSM cell-broadcast mode.

11. The mobile terminal of claim 8, further comprising:

an acoustical unit configured to announce the broadcast content; and

a display unit configured to display the broadcast content.

12. The mobile terminal of claim 8, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the at least two specific identifiers.

13. The mobile terminal of claim 12, wherein the duration of the broadcast mode is for an indefinite length of time or for a limited duration of time based on the at least one specific identifier of the at least two specific identifiers.

14. A bi-directional cellular wireless communication system adapted to implement a cell broadcast service and a paging mode, the system comprising:

a transmitter configured to broadcast content and transmit at least one paging message to a plurality of mobile terminals in a cell; and

the plurality of mobile terminals, each of the plurality of mobile terminals comprising;

a memory unit configured to store at least two specific identifiers supporting an emergency warning, the at least two specific identifiers being for different types of emergencies; and

a control unit configured to;

check whether the at least one paging message received from the transmitter includes at least one specific identifier of the at least two specific identifiers;

switch to a broadcast support mode for receiving the content transmitted by the transmitter on a broadcast channel when the at least one paging message transmitted by the transmitter includes the at least one specific identifier of the at least two specific identifiers; and

establish at least one of a physical channel and a logical channel when the received paging message includes a mobile terminal identifier allocated to the mobile terminal.

15. The system of claim 14, wherein the mobile terminal identifier is at least one of a temporary mobile subscriber identity, an international mobile subscriber identify, and a packet temporary mobile subscriber identity.

16. The system of claim 14, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the at least two specific identifiers.

17. The system of claim 16, wherein the duration of the broadcast mode is for an indefinite length of time or for a limited duration of time based on the at least one specific identifier of the at least two specific identifiers.

18. A method of communicating with a plurality of mobile terminals in a bi-directional cellular wireless communication system between a base station and the plurality of mobile terminals, the method comprising:

broadcasting, at the base station, content to the plurality of mobile terminals in a cell;

transmitting, at the base station, at least one paging message to the plurality of mobile terminals in the cell;

storing, at one of the plurality of mobile terminals, at least two specific identifiers common to the plurality of mobile terminals supporting an emergency warning, the at least two specific identifiers being for different types of emergencies;

checking, by the one of the plurality of mobile terminals, whether the at least one paging message received from the base station includes at least one specific identifier of the at least two specific identifiers;

switching, by the one of the plurality of mobile terminals, to a broadcast mode for receiving broadcast content on a broadcast channel when the received paging message includes the at least one specific identifier of the at least two specific identifiers; and

establishing, by the one of the plurality of mobile terminals, at least one of a physical channel and a logical channel when the received paging message includes a mobile terminal identifier allocated to the one of the plurality of mobile terminals.)

19. The method of claim 18, wherein the mobile terminal identifier is at least one of a temporary mobile subscriber identity, an international mobile subscriber identify, and a packet temporary mobile subscriber identity.

20. The method of claim 18, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the at least two specific identifiers.

21. The method of claim 20, wherein the duration of the broadcast mode is for an indefinite length of time or for a limited duration of time based on the at least one specific identifier of the at least two specific identifiers.
