[0005] In the ETWS system, the notification method for the UE in the idle state (IDLE), cell paging state (CELL_PCH) or UTRAN registration area paging state (URA_PCH) has been determined. Important notifications are through paging (such as paging type 1 messages) Realization, ensuring that the UE is notified within 4 seconds; and auxiliary notification is realized through Cell Broadcasting (Cell Broadcasting) or System Information Broadcasting (System Information Broadcasting), ensuring that the UE is notified within 10 seconds to 30 seconds; while 3GPP only The disaster information notification method for users in the idle state (IDLE), cell paging state (CELL_PCH) or UTRAN registration area paging state (URA_PCH) in UTRAN is determined, and the disaster notification method for users in other states is not involved, so it is necessary to provide a A feasible method to send ETWS disaster notification information to mobile terminals in CELL_DCH state or CELL_FACH state in UTRAN

Embodiment Construction
[0020] The present invention proposes a method for sending ETWS disaster notification information and important notification information to UEs in cell_dedicated channel (CELL_DCH) state or cell_forward access channel (CELL_FACH) state. RNC sends UU dedicated channel to UE through UU interface. notification message, and carry important notification information and auxiliary notification indication information in the dedicated message, the auxiliary notification indication information indicates that the auxiliary information is sent through cell broadcasting, and the RNC sends the specific content of the auxiliary information through a cell broadcast message (CELLBROADCASTING). In the CELL_DCH or CELL_FACH state, the dedicated notification message between the UE and the RNC is carried on a dedicated logical channel (DCCH, Dedicated Control Channel) or a common logical channel (CCCH, Common Control Channel), using the dedicated or public radio that has been allocated to the UE Th...

The invention discloses a method for sending important advice information and disaster advice information in a seismic sea wave system, comprising the following steps: after receiving the disaster advice information of the seismic sea wave system, a wireless network controller sends UU interface special advice information to a mobile terminal by the interface of ground wireless access network andthe mobile terminal, namely, the UU interface, wherein, important advice information is carried in the special information; and the wireless network controller sends auxiliary advice information by cell broadcast information, thereby ensuring that ETWS important advice information and auxiliary advice information can be sent to the mobile terminal in a cell-specific channel state or in a cell forward access channel state within the required time of the ETWS system, so as to achieve the requirement of the ETWS system.
Description
technical field [0001] The present invention relates to a mobile communication system, in particular to a communication system in the cell_dedicated channel (CELL_DCH) state or cell_ A method for sending important notification information and disaster notification information in an earthquake or tsunami system to a user terminal (UE, User Equipment) in a forward access channel (CELL_FACH) state. Background technique [0002] The 3rd Generation Partnership Project (3GPP, The3rd Generation Partnership Project) proposed the Earthquake and Tsunami Warning System (ETWS, Earthquake and Tsunami Warning System), which notifies users at the first moment when an event occurs or is about to occur, increasing the chances of users self-rescue and reducing Hazards from major disasters such as tsunamis and earthquakes. [0003] figure 1 The network framework diagram of the ETWS system is described. The GEC (Government ETWS Center) is the source of disaster information such as tsunamis an...
