1. 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 content of information to be broadcast;
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 the 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.

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.

7. 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 content of information to be broadcast; 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 the 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. - View Dependent Claims (8, 9, 10, 11, 12, 22)

13. 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 the broadcast content; 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 broadcast 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. - View Dependent Claims (14, 15, 16, 23)

17. 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 the broadcast content; 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 the 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. - View Dependent Claims (18, 19, 20, 24)
