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. A method of communicating with a terminal in a cellular wireless communication system, the method comprising:

storing, at the terminal of the cellular wireless communication system, a group of specific identifiers common to a plurality of terminals supporting an emergency warning, at least two specific identifiers in the group of the specific identifiers being for different types of emergencies, the cellular wireless communication system being a bi-directional cellular wireless communication system between a base station and the plurality of terminals;

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

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

establishing, by the terminal, at least one of a physical channel and a logical channel only if the received paging message includes a temporary mobile subscriber identity allocated to the terminal.

2. A method according to claim 1, 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.

3. A method according to claim 1, wherein the terminal at least one of notifies and displays to a user of the terminal the broadcast content.

4. A method according to claim 1, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the group of the specific identifiers.

5. A method according to claim 4, 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 group of the specific identifiers.

6. A method according to claim 1, wherein the group of the specific identifiers are temporary subscriber mobile identities.

7. A terminal operating in a cellular wireless communication system having a plurality of terminals, the terminal comprising:

a memory unit configured to;

store a group of specific identifiers common to the plurality of the terminals supporting an emergency warning, at least two specific identifiers in the group of the specific identifiers being for different types of emergencies, the cellular wireless communication system being a bi-directional cellular wireless communication system between a base station and the plurality of terminals; and

a control unit configured to;

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

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

establish at least one of a physical channel and a logical channel only if the received paging message includes a temporary mobile a subscriber identity allocated to the terminal.

8. A terminal according to claim 7, 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.

9. A terminal according to claim 7, further comprising:

an acoustical unit configured to notify a user of the terminal of the broadcast content; and

a display unit configured to display the broadcast content to the user of the terminal.

10. A terminal according to claim 7, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the group of the specific identifiers.

11. A terminal according to claim 10, 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 group of the specific identifiers.

12. A 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 terminals in a cell, the cellular wireless communication system being a bi-directional cellular wireless communication system between the transmitter and the plurality of terminals; and

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

a memory unit configured to;

store a group of specific identifiers supporting an emergency warning, at least two specific identifiers in the group of the 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 group of the specific identifiers;

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

establish at least one of a physical channel and a logical channel only if the received paging message includes a temporary mobile subscriber identity allocated to the terminal.

13. A system according to claim 12, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the group of the specific identifiers.

14. A system according to claim 13, 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 group of the specific identifiers.

15. A terminal operating in a cellular wireless communication system having a plurality of terminals, the terminal comprising:

a memory unit configured to store a group of specific identifiers common to the plurality of the terminals supporting an emergency warning, at least two specific identifiers in the group of the specific identifiers being for different types of emergencies, the cellular wireless communication system being a bi-directional cellular wireless communication system between a base station and the plurality of terminals; and

at least one programmed processor configured to;

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

switch to a broadcast mode for receiving broadcast content on a broadcast channel only if the paging message received from the base station includes the at least one specific identifier of the group of the specific identifiers, without waiting to confirm accurate receipt of an emergency warning message; and

establish at least one of a physical channel and a logical channel only if the received paging message includes a temporary mobile subscriber identity allocated to the terminal.

16. A terminal according to claim 15, wherein a duration of the broadcast mode is dependent on the at least one specific identifier of the group of the specific identifiers.

17. A terminal according to 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 group of the specific identifiers.
