9、4) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions a
10、nd 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 which, in turn, produce Recommendations on th
11、ese 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 IEC. NOTE In this Recommendation, the exp
12、ression “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 ensure e.g. interoperability or applicabi
13、lity) 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 does not suggest that compliance with the R
14、ecommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU 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 applicabilit
15、y of claimed Intellectual Property 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 th
16、is Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

M.3350 (05/2004) Introduction During catastrophic events, such as earthquakes, severe storms, floods, and civil unrest, governmental and other essential users of public telecommunicati
19、ons need a preferential telecommunication capability to support emergency and disaster relief operations. Telecommunication resources are often restricted during these serious events due to damage, congestion, and failures. Therefore, it is desirable to establish and manage telecommunication capabil
20、ities to support disaster relief operations that will provide a high probability of completion of emergency telecommunications. ITU-T Rec. E.106 1 describes an International Emergency Preference Scheme (IEPS) for PSTN, ISDN, and PLMN telephony services to support emergency recovery activities during
21、 crises. Certain international and national telecommunication capabilities will enable authorized users to have preferential access to telecommunication services and preferential processing of telecommunications to support recovery operations during emergency and disaster events. These capabilities,
22、 when provided nationally, are referred to as the Emergency Telecommunication Service (ETS). While some countries already have national preference schemes in existing telecommunication systems, the challenge at hand is provisioning appropriate priority mechanisms for a family of multimedia services
23、in the newly emerging generation of packet-based networks, as well as ensuring effective interoperation with existing PSTN, ISDN, and PLMN emergency services, facilitating also international telecommunications when applying ITU-T Rec. E.106. Interchange of critical service management information cou
24、ld significantly benefit emergency recovery operations. Service management information associated with ETS operations needs to be shared between SP and SC authorized to manage emergency and disaster relief operations to ensure the best possible telecommunication support is provided under the stressf
25、ul circumstances. The ETS Management Service (ETSMS) addressed by this Recommendation will provide this capability. ITU-T Rec. M.3350 (05/2004) 1 ITU-T Recommendation M.3350 TMN service management requirements for information interchange across the TMN X-interface to support provisioning of Emergenc
26、y Telecommunication Service*(ETS) 1 Scope The subject of this Recommendation is the interface between a duly authorized service customer (SC) and a duly authorized service provider (SP) that is used to manage emergency telecommunication service (ETS) features. ETS features are used by emergency resp
27、onders during disaster events for telecommunications to organize and coordinate activities for saving lives and restoring community infrastructure. The definition of actual ETS features and requirements are the subject of other Recommendations. This Recommendation describes the ETS Management Servic
28、e (ETSMS) and identifies functional requirements for interchange of critical service management information, which relates to ETS features, among TMNs across the X-interface of the service management layer as defined by ITU-T Rec. M.3010 2. The requirements described will enable authorized disaster
29、response and recovery operations personnel, as SCs, to interact with SPs to share knowledge of the availability of services, configure services, and activate required services. Some aspects of the ETSMS may be used at any time independent of the occurrence of actual emergencies. Other TMN Recommenda
30、tions will cover the specific format and data elements as well as the protocols for interchange of management information across the X-interface for the ETSMS. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute p

M.3350 (05/2004) 3 Terms and definitions This Recommendation defines the following terms: 3.1 availability: The measur
36、e of ability of the network resources to support ETS or ETSMS features that could be used as activated or to be activated by authorized users supporting emergency and disaster relief operations. 3.2 degradation: A state of the ETS in which the quality of service level falls below a minimum threshold
37、 specified in the service level agreement between SC and SP. 3.3 ETS Management Service (ETSMS): A management service that provides capabilities for interchange of critical service management information, which is related to available ETS features, between service customers and service providers res
38、ponsible for disaster relief operations to recover from catastrophic events. 3.4 failure: Loss of capability to support ETS communications or the ETSMS. 3.5 Service Level Agreement (SLA): A Service Level Agreement (SLA) is a formal negotiated agreement between two parties. It is a contract that exis
39、ts between the Service Provider (SP) and the Service Customer (SC). It is designed to create a common understanding about service, quality, priorities, responsibilities, etc. SLAs can cover many aspects of the relationship between the SC and the SP, such as performance of services, customer care, bi
40、lling, service provisioning, etc. 3.6 ETS network operator: An authorized organization that operates a telecommunication network and provides ETS features for ETS service users. An ETS network operator may be a SP and vice versa. 3.7 ETS service customer: A designated manager of the ETS features and
41、 the recognized user of the ETSMS. There may be different levels of SCs from national and regional down to the immediate local disaster area. The Service Level Agreement (SLA) for the ETS and ETSMS is between the SC and SP. 3.8 ETS service provider: An authorized service provider of the ETS features
42、 and the ETSMS. 3.9 ETS service user: The ETS service user (SU) is authorized by the SC to use the ETS features. The SU is not a user of the ETSMS. 4 Abbreviations and acronyms This Recommendation uses the following abbreviations: ETS Emergency Telecommunication Service ETSMS ETS Management Service

45、ecovery requires rapid response by local, regional, and national authorities, immediate reaction from utility service providers, and support from medical, recovery, fire, police, and construction resources. Effective communications are essential to facilitate the myriad of activities required for or
46、ganizing and coordinating lifesaving efforts concurrent with re-establishing control in the disaster area and restoration of the community infrastructure. Effective telecommunication services are imperative to the success of disaster recovery and mitigation operations. Emergency and disaster relief
47、operations require extensive coordination and cooperation by organizations involved in restoring the infrastructure and for the well being of the society impacted. During these disaster situations, telecommunication services are often severely disrupted through facility damage as well as congestions
48、 due to significantly increased telecommunication traffic. Operations centres may be established or activated to coordinate the myriad of activities that are required to recover from the destruction, locate missing people, save lives, recover the infrastructure of the community, and restore normal l
49、iving conditions for the population. ETS telecommunications to support these emergency recovery operations are given preferential access and processing treatment (e.g., as specified in ITU-T Rec. E.106). The ETS Management Service (ETSMS) provides online interchange of critical telecommunications management information, which is associated in real time with provision of ETS features, and will significantly facilitate and benefit recovery operations. These interactions will more efficiently and effectively facilitate provisioning of essen
