11、isaster relief mobile message service. In the aftermath of a disaster, communication facilities are often overloaded due to many users attempting to contact friends or relatives to determine the safety of people who may have been affected by disasters. As a result, communication attempts often fail.
12、 The intent of a disaster messaging service is to allow an alternate method to communicate safety status information. Two approaches are presented. The first is a text-based messaging system, and the second is a voice-based messaging system. History Edition Recommendation Approval Study Group Unique

14、RD The International Telecommunication Union (ITU) is the United Nations 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 t
15、echnical, operating and tariff questions and issuing Recommendations on 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 whi
16、ch, in turn, produce Recommendations on these topics. The approval of ITU-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
17、 IEC. NOTE In this Recommendation, the expression “Administration“ is used 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
18、 ensure, e.g., interoperability or applicability) and compliance with the 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

26、endation ITU-T E.108 Requirements for a disaster relief mobile message service 1 Scope This Recommendation specifies requirements for a disaster relief mobile message service. After a disaster occurs, many people want to contact their immediate family, relatives or friends to report their condition.
27、 In many cases, communication is via telephone over the mobile or fixed telephone network. However, due to a large population of users attempting to make similar calls, they often fail to get through due to heavy network congestion. In contrast, the characteristics of Internet protocol (IP) packet n
28、etworks are such that, although localized congestion may occur, the user does not experience blocking to the extent that communication is fully cut off, but still has the ability to transfer information, although with possibly reduced throughput. As an alternative to using a mobile or fixed telephon
29、e network after disasters occur, an IP-based disaster relief message service provided through the mobile network enables people to inform their friends and family members of their safety or of damage conditions. 2 References The following ITU-T Recommendations and other references contain provisions

33、ty or a society involving widespread human, material, economic or environmental losses and impacts, which exceeds the ability of the affected community or society to cope using its own resources. 3.2 Terms defined in this Recommendation This Recommendation defines the following terms: 3.2.1 disaster

38、ily members of their safety or of the damage situation. At the same time, the friends and family members not directly affected may also try to directly confirm the safety of the possible victims. Normally, the first attempt by both parties is to try to contact each other using either a mobile or fix
39、ed voice telephone network. However, call attempts may fail due to heavy congestion caused by the sudden increase of traffic and the possible drop of network capacity if the network itself is damaged by the disaster. In comparison with a real-time voice call service, a packet service can be employed
40、 to transfer messages related to safety confirmation or the damage situation in off-peak hours (or even in busy hours), if the service is designed as a store and forward service. Also, as a packet-based system, a disaster message board service (see clause 3.2.3) generally requires less network capac
41、ity than a voice telephony based service. The current generation of mobile phones provides a packetized data service. As many victims often flee a disaster situation taking with them a device such as a mobile phone, smartphone or tablet, a message system operating in conjunction with the mobile netw
42、ork is appropriate. Considering these situations above, two types of disaster relief (see clause 3.2.1) mobile services are possible; one is an IP message-based service and the other is an IP voice-based service. In the case of an IP-message based service, with a mobile phone victims can easily info
43、rm their friends and family members of their safety or of the damage situation. After the victim provides safety information (or information related to the damage situation) to a packet-based disaster relief system (see clause 3.2.2), their friends and family members can independently retrieve this
44、information from the system. Some people may prefer a live voice-based communication system. In some situations, voice-based calls may be the only option for some (such as the aged or infirm). In this case, the system can allow storage of a digitized voice message, which can then be accessed by thei
45、r friends and family members through the IP network. NOTE The word “victim“ in this document is the person who might be affected by disaster. Rec. ITU-T E.108 (01/2016) 3 6.2 Concept of an IP message-based service For an IP message-based service, victims can input into their mobile phone the disaste
46、r relief message, which may include information such as confirmation of their safety and the damage situation. The mobile phone terminal transfers the message to a server called a disaster message board via the mobile network. Their friends and family members can then access the server and retrieve
47、this information by accessing the web through a mobile phone or Internet terminal. In addition, the user (victim) can arrange to have the message automatically delivered to specific mobile phone numbers to notify his safety-confirmation and damage situation. The concept of a disaster message board s
48、ervice is shown in Figure 1. Figure 1 Disaster message board service In some countries, disaster message board services may be independently provided by each service operator. In this case, to minimize the inconvenience to users, the system is required to provide a cross-search function to allow sea
49、rching, even by foreign users, of all databases (DBs) for safety information provided by the users. By inputting the phone number of friends and family members, the message-receiving users can identify the situations of friends and family members after cross-searching as shown in Figure 2. 4 Rec. ITU-T E.108 (01/2016) Figure 2 Cross-searching function on databases of different message boards The requirements for a disaster message board service are specified in clause 7. 6.3 Concept of IP voice-based servi
