11、 Recommendation ITU-T E.119 describes the requirements for safety confirmation and broadcast messaging for disaster relief, which can realize public organizations business continuity plans (BCP) and can, to the best of their ability, help protect lives and property during a disaster. In the event of

12、 a disaster, it is very important that public organizations, such as telecommunication companies, electric power companies, hospitals, fire departments and local governments continue to operate and help save the lives of victims. Confirmation of the safety of officials or company staff is important

13、in order to continue operating their necessary tasks. In addition, to be effective, broadcast message systems should automatically confirm the status of officials or staff.

15、s specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on

16、 them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of I

17、TU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is u

18、sed for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with t

19、he Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required o

20、f any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Pr

21、operty Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However,

25、ry important that public organizations such as telecommunication companies, electric power companies, hospitals, fire departments and local governments, continue to operate and help save the lives of victims. For example, telecommunication companies should provide telecommunication services to enabl

26、e safety confirmation and emergency telecommunication immediately after a disaster, and local governments should aggregate information about disaster victims and the situations in affected areas. Confirming the safety of officials or company staff is important because managers need to organize offic

27、ials or staff members in order to continue operations. In addition, managers need to communicate with officials or staff to ensure the continuity of operations and to share accurate information, which is essential in emergency situations. Broadcast message systems are required to accomplish this. Re

28、c. ITU-T E.119 (04/2017) 1 Recommendation ITU-T E.119 Requirements for safety confirmation and broadcast message service for disaster relief 1 Scope This Recommendation describes the requirements for safety confirmation and broadcast messaging services for disaster relief. During and after a disaste

29、r, public organizations such as hospitals, local governments and telecommunication service providers need to continue their business as best as possible, in order to help save the lives of victims. Most public organizations have put in place business continuity plans (BCP) for use during a disaster,

30、 and it is important to implement the BCP in order to provide as many public services as possible. In the event of a disaster, the safety confirmation system is used to confirm staff status, such as their availability, and the broadcast message system communicates directives to available staff in or

31、der to enable them to continue functioning effectively. Public organizations can implement their BCP by using the safety confirmation and broadcast message system, and can protect the lives and property of victims to the best of their ability. NOTE The word victim in this Recommendation is used to d

32、enote a person affected by a disaster. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

39、es businesses to continue to operate even during a disaster. The plans are made before a disaster and are used by public organizations mainly to save the lives of victims. 3.2.2 safety confirmation: Information about the safety of users who might be affected by a disaster to be collected and managed

40、 at more than one site, and to be reported to specified person. 3.2.3 victim: A person affected by a disaster. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations and acronyms: BCP Business Continuity Plan DTN Delay Tolerant Networks IoT Internet of Things NGN Next Gene

42、tinue to operate as normal as possible. For such public organizations, using a cloud-based safety confirmation and broadcast message service is a suitable way to check on the status of members of these organizations to confirm their safety and dispatch available people to appropriate work sites. Thi

43、s service is divided into two parts. The first is safety confirmation, as shown in Figure 1, and the second is broadcast messages, as shown in Figure 2. Rec. ITU-T E.119 (04/2017) 3 Figure 1 Concept of safety confirmation Figure 2 Concept of broadcast message operations In order to continue working

44、effectively during disasters, the managers of public organizations must first confirm the safety of the people working in their organization, and then dispatch available staff to appropriate work sites to continue operations. In this sense, the flow direction of the notification is Public organizati

45、on to staff of the organization. Figure 1 shows the procedure of safety confirmation. When disaster information is notified by the meteorological bureau, safety confirmation can be started even if managers cannot operate the system as registration of disaster and sending safety confirmation requests

46、 run automatically (step 1). After requesting safety confirmation requests, the staffs of the organizations send their status to the manager (step 2). The managers recognize status of staffs and their family (step 3). Then, in order to dispatch available persons to appropriate work sites in order to

47、 keep the businesses running, the managers call disaster countermeasures staff by broadcasting messages (step 4). In this case, the direction of flow of information is also Staff of the public organization to the organization, so the direction Public organization to the staff of the organization is

48、bidirectional. 4 Rec. ITU-T E.119 (04/2017) 7 Requirements Safety confirmation and broadcasting message service for disaster relief must provide the following functions: 7.1 High-reliability/availability The system itself must be highly reliable and readily available, since the system is used during

49、 and after a disaster. The following six elements are considered for the system: 1) Data redundancy Data synchronization and redundant server configurations are needed for storing users contact information in the case of an emergency. 2) Geographical distribution of data centres Several secure data centres located in geographically diverse locations are required to prevent the damage at one data centre from impacting the overall service, enabling services to continue in the case of an emergenc
