Introduction Emergency Telecommunications (EMTEL) have taken much importance and requirements on the functional
15、architecture for supporting Emergency and Priority user services are needed from the expressed users needs which depend of: the type of user (User, Government agency, Business, Law enforcement, Emergency); the type of operation (Day to day, Emergency, Disaster); the phase of the emergency (Risk asse
16、ssment, Response, post Disaster); the localization of the user (On disaster site, outside disaster site); the service characteristics (Voice call, Data transmission, Conference call). Typically this concerns: communications of Citizens with Authorities; communications between Authorities; communicat
17、ions from Authorities to Citizens; communications of Authorities with the Emergency multi-disciplinary teams; communications of Authorities with Agencies to get information from Information Systems. ETSI ETSI EG 202 339 V1.1.1 (2004-09) 5 The objectives and requirements should include priority, inte
18、roperability, reliability, security and functionalities depending of the users and communications networks: wired or wireless; public or private; legacy or future. A common set of services has to be identified. Typical scenarios, corresponding to the list above, have to be identified, in order to us
19、e them as reference scenarios. New areas of standardization may be found from the requirements. This could be applicable to Homeland Security. ETSI ETSI EG 202 339 V1.1.1 (2004-09) 6 1 Scope The present document defines requirements and proposes a functional architecture of an Emergency Telecommunic
20、ation Service for international cooperation in Europe. It clarifies definitions of the different actors. It classifies the concerned users, types of services offered, timing and location of the events requiring Emergency Telecommunications Service. It refers to the existing models, while protocols a
21、daptations are being developed in ITU T and R, ETSI, IETF and other organisms of standardization and forums. It defines the requirements for a functional architecture to support Emergency and Priority user services based on the services asked by the users concerned, through: The European Commission
22、and Civil Protection (EGERIS) 7; ETSI Emergency Telecommunications (EMTEL) 9; ITU-R and T Public Protection and Disaster Relief (PPDR), Emergency Telecommunication Service (ETS), Telecommunication Disaster Relief (TDR) 3; ETSI TETRA Users Requirements (URS) 6; IETF Internet Emergency Prepareness (IE
23、PREP) 8; ETSI-TIA MESA Specifications of Requirements (SoR) 1. It proposes a list of services needed in a phasing to define. NOTE: The term requirement means a capability which may be part of the ETS service, dependant on national decision and technical feasibility. 2 References The following docume

30、eceives the emergency calls (e.g. 112) and takes in charge these calls, answering and handling them to the right entity NOTE: It may interoperate with control centres. It is also referred as Contact centre, PSAP (Public Safety Answering Point). control centre: node of a network getting information f
31、rom network connected Data Bases (GIS) for display, computing and which is in contact and monitoring the interdisciplinary emergency teams on site (Voice, Data, Location) NOTE: It may be connected to other control centres for information exchange, connected to administrations networks. It is also ca
32、lled Command and Control Centre, Operational and Tactical Centre, Monitoring and Information centre, Computer Aided Dispatch, Emergency Operation Centre. user: any entity that actually establishes communication with an emergency response centre service, Control Centre NOTE: It includes Civilians als
33、o referred as citizens, mission critical users, government agents, relief organizations. relief organizations can include the following: Emergency authorities; Public Utilities; Government authorities; Agents/applications; Private Service Providers. inter-working: ability of equipments to communicat
34、e together from different systems and with similar services NOTE: Those equipments are not roaming from one system to a different one. interoperability: ability of equipments from different manufacturers (or different systems) to communicate together on the same infrastructure (same system), or on a
35、nother while roaming location based services: specific services offered depending of the user geographical location like mapping services, points of interest, routing services portability: ability of an entity or element to be used in different systems or environments ETSI ETSI EG 202 339 V1.1.1 (20
36、04-09) 8 roaming: process of changing the network access point from one Location Area, Network or Domain to another within one system or between different systems NOTE: This may include different systems using the same technology. gateway: interface, between two (or more) systems that have similar f
37、unctions but dissimilar implementations, enabling users on one network to communicate with users server: server is an application program that accepts requests in order to service those requests and send back responses to those requests 3.2 Abbreviations For the purposes of the present document, the

41、iverse with their specific services adapted to different markets including the Emergency one. - ETSI has launched EMTEL. - International Emergency Preference and Multimedia Schemes are being specified by ITU-T, -R, -D 3, 4, 5 and other organizations and projects such as IETF (IEPREP) 6, 7, 8, 3GPP (
42、PAS), GETS (USA), IAA (Japan) in order to set up procedures and processes for handling emergency communications. - It should be made clear that many of these procedures are mainly applicable in Day to Day operations, when the corresponding telecommunications infrastructures are still up and running.
43、 - They do not apply when the situation corresponds to large emergency or disasters. In such cases fixed and mobile public networks are usually totally congested and/or partly destroyed. - Sers specifications start being collected 1, 2,6. - European specificities should be considered in particular f
