Description

Method for transmitting disaster notification information and emergency notification information in emergency alarm system

Technical field

The present invention relates to the field of wireless communications, and in particular, to a method for transmitting disaster notification information and emergency notification information in an emergency alarm system.

Background technique

Mobile phones are the most commonly used communication devices. The 3rd Generation Partnership Project 3GPP (3rd Generation Partnership Project) introduces a new service to the public in the 3GPP TS (Tech Specification) 22.168 technical specification. The Earthquake and Tsunami Warning System (ETWS), and the purpose and technical features of the system are described in detail. The Earthquake and Tsunami Warning System ETWS provides a means of transmitting disaster notification information to people in need of evacuation in earthquake or tsunami areas. With the widespread use of mobile communication devices, mobile users are notified at the first moment of an event or imminent event. Users can decide when and where to evacuate according to the received alarm notifications, increasing the chances of users to save themselves, thus effectively reducing the damage to people's lives and property caused by major disasters such as earthquakes or tsunamis.

The ETWS system classifies disaster notification information into two categories, one is Primary Notification and the other is Secondary Notification.

The emergency notification is used to notify the user of the type of disaster, such as the type of disaster, and is the most urgent notification of the second level. After receiving the terminal, the terminal uses vibration or buzzer to remind the user to save himself in time. The 3GPP TS 22.168 technical specification requires urgent notifications to be sent from the information source to the users in the range within 4 seconds regardless of whether the network is congested. Therefore, the data volume of an emergency notification needs to complete fast and effective information transmission, usually in several words. The text format of the section is sent.

The secondary emergency notification is used to inform the user of auxiliary information, such as: emergency handling guidance information / obtaining help locations (rescue equipment, food distribution schedule), etc., usually issued by the local government. The transmission of the secondary emergency notification is required in the 3GPP TS 22.168 technical specification, regardless of whether the network is congested or not, and needs to be transmitted from the information distribution source to the user in the range within 10 seconds to 30 seconds. Since the secondary emergency notification is an auxiliary guidance or help information for the emergency notification, The amount of information is much larger than the urgent notice. Generally, the text and language are used. Prompt (for example, how to do / where to get help, etc.), geographic data (such as: route map indicating the current location to the evacuation location), food distribution schedule, and other media formats.

For the network architecture planning of ETWS, 3GPP describes various radio access technologies in TS 23.828 protocol, such as: Global System for Mobile Communications / Enhanced Data Rate Global Evolution System Radio Access Network GERAN (GSM/EDGE Radio Access Network , Global System For Mobile Communication/Enhanced Data Rate for GSM Evolution Radio Access Network ), Universal Terrestrial Radio Access Network (UTRAN) and Enhanced Universal Terrestrial Radio Access Network (E-UTRAN) . How to send alarm notifications to different users quickly and efficiently through different wireless access technologies. The preferred cell broadcast center CBC (Cell Broadcasting Centre) is used as the information service center of ETWS, using wireless access technology GERAN, UTRAN. Or the E-UTRAN network exchanges ETWS information with the Service Area Broadcast Protocol (SABP) through the Iu-BC interface (the interface between the CBC and the radio network controller RNC). The cell broadcast service CBS (Cell Broadcast Service) message transmitted by the SABP bearer is composed of multiple pages, each page contains 82 bytes (using the default character set equivalent to 93 characters), and a piece of CBS information can be connected by up to 15 pages of data. composition. Two types of ETWS notifications are transmitted to the radio access network in a write-alternate (WRITE-REPLACE) message.

As shown in FIG. 1, a method for transmitting ETWS information to a user equipment (UE, User Equipment) by using a CBS message includes the following steps, where the UE is in IDLE (idle state), CELL PCH (cell paging state), or URA_PCH (UTRAN registration) District paging status); Step 101, Government ETWS Centre collects or predicts that TBWS disaster notification information will be sent to CBC when disaster events such as tsunami and earthquake occur or are about to occur; ETWS disaster notification information The emergency notification information and the secondary emergency notification information are included; Step 102, the CBC sends a Write-Replace message to the RNC; the write-substitute message includes emergency notification information and secondary emergency notification information;

Step 103: The RNC completes CBS service control (broadcast information scheduling and radio resource allocation). That is, the CTCH (Common Traffic Channel) data is transmitted to the UE after the allocation of the FACH (Forward Access Channel) and the Secondary Common Control Physical Channel (SCCPCH) and the modification of the scheduling system information. 1 ( PAGING The TYPE1 message, which carries the content information of the ETWS notification, includes: the type of the emergency notification (ie, an earthquake or tsunami) and the secondary emergency information reading mode information of the related emergency notification. The RNC (Radio Access Network) encodes the ETWS emergency notification type and the secondary emergency information reading mode information of the related emergency notification type in the International Mobile Subscriber Identity (IMSI) format.

Step 104: After receiving the paging type 1 message sent by the RNC, the UE learns the emergency notification type, and alerts the user to the disaster information by means of an emergency alarm mode (such as ringing or vibration); the UE also learns through the paging type 1 message. The secondary emergency information reads mode information to indicate how the UE receives the secondary emergency notification information.

Step 105: The RNC sends a broadcast multicast control scheduling message (Broadcast/Multicast Control)

The Schedule Message (BMC Schedule Message) provides the UE with a discontinuous reception indication of the cell broadcast data. Ensure that the ETWS introduces the secondary emergency notification information that does not affect the original cell broadcast service architecture and ensures the UE's maximum degree of reception of the ETWS in the power saving mode.

Step 106: The RNC sends the CBS information of the cell broadcast service carrying the ETWS secondary emergency notification to the UE. The UE reads the secondary emergency notification information according to the secondary emergency information read mode obtained in step 104. Step 107: The RNC returns a write-alternate message to the CBC. Successful report ( BMC REPORT-SUCCESS );

Step 108: The CBC returns an ETWS response message to the GEC, and the process ends.

It can be seen from the above process that the implementation of ETWS transmission by CBS technology can satisfy the effective transmission of emergency notification. However, for the colorful media form of auxiliary information in the secondary emergency notification, the CBS technology bearer obviously cannot satisfy the information transmitted to the user. Demand.

Preferred embodiment of the invention

In the Multimedia Broadcast I Multicast Service (MBMS) technology, a data source transmits point-to-multipoint services of data to multiple users, which enables network resource sharing, including resources of the mobile core network and the access network. , especially the sharing of air interface resources. MBMS defined by 3GPP can not only realize plain text low-rate message class multicast and broadcast, but also realize high-speed multimedia service multicast and broadcast, which undoubtedly conforms to the mobile data development trend of ETWS service sub-emergency notification. The MBMS service has been effectively applied in the mobile network. The service has no uplink channel. The physical channel carrying the service and signaling uses the point-to-multipoint (PTM) mode to transmit the same as the CBS service on the SCCPCH. on. However, its Broadcast-Multicast Service Centre (BM-SC) can deliver richer multimedia data, and expands the problem of single transmission data and limited capacity of CBS technology, which can meet the secondary emergency notification users in the ETWS service. The diversity of forms of demand information.

In the present invention, the MBMS technology is used to carry the emergency alarm information to notify the emergency alarm information to the UE in the idle state, the CELL-PCH (Cell-Paging Channel) and the URA-PCH (UTRAN Registration Area-Paging Channel) state, as shown in FIG. 2 As shown, including: Step 201: The BM-SC of the core network initiates a session start process, and the emergency alert information is notified to the UTRAN in a session start manner of the MBMS service, where the session start message includes primary notification information and secondary emergency notification (secondary notification). Wireless access 7 messages;

Step 202: The UTRAN sends a paging type 1 message to the UE, where the message carries an emergency notification.

(Primary Notification), and send the Secondary Notification to the UE with MBMS radio access.

As shown in FIG. 3, the method for using the MBMS technology to carry emergency alert information to notify the UE of the emergency alert information includes the following steps:

Step 301: The GEC manages the ETWS service information in the core network, and the GEC transmits the ETWS emergency alarm information to the BM-SC, where the information includes an emergency notification and a secondary emergency notification;

The GEC and the BM-SC belong to the core network, and the connection between them is connected by Ethernet. The information exchange is defined by internal interfaces or defined by standard specifications.

The secondary emergency notification information is not limited to a text mode, and may be a video, an image, a picture, or the like. Step 302: After receiving the ETWS information, the BM-SC starts the MBMS session start process, where

The MBMS session start request (Session Start Request) message carries the ETWS emergency notification identifier to the RNC, indicates the start of the ETWS service, and carries the MBMS RAB (Radio Access Bearer) information of the Secondary Notification (Secondary Notification). The MBMS radio access bearer information includes one or more of the following parameters: session attribute, QoS (quality of service), MBMS service area, session identifier (Session identifier), session duration ( Estimated session duration), and MBMS data transmission bearer. Address, etc.

Step 303: The RNC receives the MBMS session start request message, stores the session attribute, and allocates a transmission network IP transmission address to the session. The emergency notification type information of the ETWS is notified to the UE through the paging type 1 message (in which the IMSI uses the special ETWS service code), and carries the relevant secondary emergency notification assistance configuration information.

The combination of the MCC (Mobile Country Code) and the MNC (Mobile Network Code) of the IMSI (International Mobile Subscriber Identification Number) in the Paging Type 1 message is identified by a special general emergency alert information, such as MCC=901. , MNC=08 (also To be set to other values, the MCC code and MNC are currently reserved for use by 3GPP, therefore, to ensure that the IMSI identity is unique. The MSIN (Mobile Subscriber Identity) in the IMSI carries emergency notification information and secondary emergency notification assistance configuration information, and the secondary emergency notification assistance configuration information includes a technology type (such as MBMS technology) for carrying the secondary emergency notification, a wireless configuration reception time, and the like.

The coded information in the MSIN contains: a) the area indicates the demand; b) the expected UE wake-up behavior

(eg: receiving emergency information to send special sounds, vibrations, etc.); c) emergency type (eg: tsunami, earthquake); d) secondary emergency notification auxiliary configuration information (eg: technical type of carrying emergency notification, wireless access bearer) e) Security information support (eg: Whether to support secure reading, and security policy can use the operator to authorize the UE mode. If the system indicates support, the default system and the UE agreed security implementation policy).

In this step, the MBMS radio access bearer information according to the secondary emergency notification, the RNC, also uses the radio resource allocation policy to preferentially configure the radio transmission resource for the secondary emergency notification MBMS radio access bearer and configure the radio resource in the following modification period. Notifying the UE, so that the UE reads the radio resource configuration information of the secondary emergency notification in a subsequent MBMS modification period;

Step 304: After receiving the paging type 1 message, the UE parses the ETWS emergency notification information, and alerts the user to the disaster information by means of an emergency alarm mode (such as ringing or vibration); the UE receives the paging type 1 message. Knowing the type of technology that carries the secondary emergency notification, enabling the corresponding receiving technology, and obtaining the radio resource configuration information of the secondary emergency notification from the RNC;

Step 305: The RNC returns an MBMS session start response message success message.

Step 306, after the BM-SC receives the RNC to start the response message with the MBMS session, the BM-SC will

ETWS secondary emergency notification information is sent in the form of MBMS service data;

Step 307: The RNC receives the MBMS service data of the ETWS secondary emergency notification, and broadcasts the radio transmission resource configured in step 303.

Step 308: The UE uses the radio resource configuration information to indicate the radio transmission resource configuration control message for receiving the multimedia broadcast multicast by using the radio resource configuration information, and configures the emergency notification information after the radio transmission resource succeeds. Notifying the user of the content of the secondary emergency notification information;

Step 309, the BM-SC sends a successful response to the GEC feedback information, indicating the ETWS service. The process is completed and the process ends.

The secondary emergency notification information of the emergency alarm information is broadcasted by the MBMS service data on the radio resource configured by the corresponding RNC. At this time, the UE that has obtained the emergency notification listens to the emergency notification information, and receives the multimedia self-help help information of the relevant alarm.

As described above, with the technical solution of the present invention, the original architecture of the MBMS is maintained, which can meet the technical requirements of the 3GPP TS 22.168, and can relatively extend the secondary emergency notification of the ETWS to transmit information bandwidth restrictions in the CBS technology, so that the ETWS information More effective and visual for user services.

However, the method is not limited to ETWS, and the ETWS is an emergency alarm system, so the method can be extended to the information transmission of the emergency alarm system of the mobile communication.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
