Benefits of technology

[0039]The mobile communications system in accordance with the present invention notifies the presence or absence of emergency information to the mobile terminal with the description of the flag disposed in the control channel for the broadcast type multimedia service and showing the presence or absence of emergency information. Ther

Problems solved by technology

However, this nationwide instantaneous alert system using speakers to notify, by voice, emergency information causes a case in which those who live in an area distant from the speakers and so on cannot know the emergency information.
There is a risk of collision.
Because conventional mobile communications systems are constructed as mentioned above, a problem with them is that they are easily affected by the influence of the load on the communications line when they are used as a system for broadcasting emergency information to an indefinite number of users, the area in which emergency information can be delivered is narrow, and the immediacy of the information may be impaired.
Therefore, because the service depends upon the capacity of the communications line between the base station and the mobile terminals, there occurs a case in which the load on the communications line increases and therefore the conventional system cannot notify emergency information to the mobile terminals when the number of users to whom the conventional system notifies the emergency information increases.
Therefore, the conventional system is not suitable for notification of emergency information to an indefinite number of users.
Furthermore, in a conventional system that notifies emergency information by using digital terrestrial broadcasting, as compared with a system using a mobile communications network, there are many locations where the receiving characteristics of digital terrestrial broadcasting waves degrade, such as an indoor, the shade of a building, and an underground shopping area, and there may be a case in which emergency information cannot be broadcast precisely.
In addition, because it is necessary to add hardware used for receiving digital terrestrial broadcasti

embodiment 1

[0060]In accordance with this Embodiment 1, an emergency information flag (an emergency information indicator) indicating the presence or absence of emergency information is disposed in an MCCH which is an MBMS control channel, and a mobile terminal is enabled to check the presence or absence of the emergency information at regular intervals. Accordingly, even while receiving information other than the emergency information by using an MBMS, the mobile terminal can recognize the existence of the emergency information by using the emergency information flag, and can receive an emergency information channel included in the MBMS.

[0061]FIG. 1 is a diagram showing the structure of a mobile communications system in accordance with the present invention. In this system, emergency information is notified to all mobile terminals 1 which support the MBMS by using the MBMS. In FIG. 1, the mobile communications system in accordance with the present invention is provided with mobile terminals 1, ba

embodiment 2

[0131]A mobile communications system in accordance with this Embodiment 2 notifies the occurrence of emergency information to even a mobile terminal which is communicating individual data, such as data about a voice call or packets, but is not receiving any MBMS data, thereby enabling the mobile terminal to receive an emergency information channel included in an MBMS.

[0132]Although the fundamental structures of each mobile terminal, each base station, and each base station control apparatus which are disposed in the mobile communications system in accordance with Embodiment 2 are the same as those according to above-mentioned Embodiment 1 shown in FIGS. 1 to 5, they differ from those of Embodiment 1 in that when emergency information occurs, each base station transmits an MICH to mobile terminals before transmitting an MCCH, and a mobile terminal which is communicating individual data, such as data about a voice call or packets, but is not receiving any MBMS data receives the MCCH acco

embodiment 3

[0154]A mobile communications system in accordance with this Embodiment 3 is constructed in such a way as to notify the occurrence of emergency information to even a mobile terminal placed in an idle state in which it is not receiving any MBMS data to enable the mobile terminal to receive an emergency information channel included in an MEMS.

[0155]Although the fundamental structures of each mobile terminal, each base station, and each base station control apparatus which are disposed in the mobile communications system in accordance with Embodiment 3 are the same as those according to above-mentioned Embodiment 1 shown in FIGS. 1 to 5, they differ from those of Embodiment 1 in that when emergency information occurs, each base station transmits an MICH to mobile terminals before transmitting an MCCH, and a mobile terminal placed in an idle state in which it is not receiving any MBMS data receives the MCCH according to the description of the indicator of the MICH, and then determines the
