Title:
MOBILE TERMINALS, AND EARTHQUAKE AND TSUNAMI WARNING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/070862
Kind Code:
A1
Abstract:
An ETWS and mobile terminals are provided. The ETWS comprises a macro base station, an HeNB and the mobile terminals (1). Each mobile terminal (1) comprises: a receiving unit (11) that receives paging and broadcast information; a movement control unit (15) that controls the receiving unit (11) to receive paging from the macro base station as well when the mobile terminal (1) is idle during connection to the HeNB; a broadcast information processing unit (13) that, when the received paging indicates the presence of ETWS information, processes the broadcast information transmitted from the macro base station to receive the ETWS information; and an ETWS information transmitting unit (16) that transmits the ETWS information to the HeNB. The HeNB then transmits the ETWS information transmitted from the mobile terminal (1) to another mobile terminal (1). This can reduce the load of transmitting the ETWS information to a large number of home base stations.
