Embodiment Construction

[0014] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0015] After receiving the SIB11 issued by the core network, the base station issues paging-etws and SIB1-etws, and sends SIB11 in the SI cycle where SIB11 is located, and continuously sends SIB11 in the subsequent SI cycle where SIB11 is located to pass it on to all on-network Compared with the number of times of sending SIB11 information three times in the original alarm protocol, the terminal equipment can increase the chance of receiving alarm information by sending a large number of high-density SIB11 information.

[0016] After receiving the paging-etws and SIB1-etws issued by the base station, the terminal device tries to receive the SIB11 information, and after confirming the receipt of the SIB...

Abstract

A method for un-intermittently and continuously sending assistance information is provided in the present invention. The method comprises that: a base station side apparatus distributes paging paging-etws indicated by an earthquake and tsunami warning message and SIB1-etws with SIB ( System Information Block ) 11 scheduling information after receiving assistance information SIB11 information distributed by a core network; and the base station side apparatus un-intermittently and continuously sends SIB11 in the subsequent SI period of SIB11. A terminal apparatus receives the SIB11 information after receiving the paging-etws and SIB1-etws distributed by the base station, and parses warning characters for users after receiving the SIB11 information from the base station. The invention has the advantages of increasing the number of sending SIB11 and improving the capability of the terminal to obtain an asking-for-help message.

Description

technical field [0001] The invention belongs to the field of wireless communication networks, in particular to a method for sending auxiliary information in an earthquake and tsunami warning system of the fourth generation mobile communication. Background technique [0002] In countries where earthquakes and tsunamis occur more frequently, it is particularly important to promptly issue warnings of earthquakes and tsunamis and evacuation to the public. Poor information directly endangers life safety. As a standard of 3GPP, LTE supports emergency warning notification of earthquake and tsunami, which is called Earthquake and tsunami warning system (ETWS, Earthquake and tsunami warning system). ETWS includes main information (SIB10) and auxiliary information (SIB11). ETWS sends SIB The (System Information Block) message informs the public of the earthquake occurrence (SIB10) and auxiliary information such as evacuation sites and supplies (SIB11). [0003] The LTE protocol stipu...
