Foreword This Special Report (SR) has been produced by ETSI Special Committee Emergency Communications (EMTEL). ETSI ETSI SR 002 777 V1.1.1 (2010-07) 51 Scope The pres
13、ent document outlines a test procedures for emergency calls from individuals (citizens) to authorities. In order to test (in a given environment) the emergency call/messaging capability of the current operator it would be favourable to have a test procedure, i.e. to be able to call a “test“ address
14、not invoking a real emergency call. Such a test could be initiated either manually or automatically (e.g. with a given periodicity). It is advised to observe the threats in security vulnerability and of network overload. Such a procedure should work both for calls from CS and PS networks (wired or w
15、ireless). The testing functionality may also be utilized in order to facilitate other location based/dependent services as described in TS 123 271 i.8. As for emergency services, both CS and PS PSAPs should be catered for. The aim of the present documents is to make a contribution to an overall func
16、tional architecture and specification for such a test service. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

30、lowing apply: Access Network Provider (ANP): provides physical access to the network dispatch location: location used for dispatching responders to the person in need of assistance NOTE: According to i.5 “the dispatch location must be sufficiently precise to easily locate the caller; it typically ne
31、eds to be more accurate than the routing location“. IP service Provider (ISP): provides access to the IP network, allocates IP addresses to users and route their traffic location configuration: location configuration is the process in which an endpoint learns its physical location ETSI ETSI SR 002 7
32、77 V1.1.1 (2010-07) 7Location Configuration Protocol (LCP): protocol used by an endpoint to learn its location location conveyance: location conveyance delivers location information to another element location determination: location determination finds where an endpoint is physically located EXAMPL
33、E: The endpoint may contain a GPS receiver used to measure its own location or the location may be determined by a network administrator using a wiremap database. Location Information Server (LIS): location Information Server that stores location information for retrieval by an authorized entity NOT
34、E: The LIS maps network addresses or equipment IDs to physical locations. No Access Authorization (NAA): current access network requires access authorization and the caller does not have valid user credentials NOTE: This includes the case where the access network allows pay-per-use, as is common for
35、 wireless hotspots, but there is insufficient time to pay for access. No Voice service Provider (NVP): caller does not have a Voice (over IP) Service Provider (VSP) at the time of the call physical location: physical location, as used here is where a person or device is located in physical space, de
36、scribed by a coordinate system or a civic address NOTE: It is distinguished from the network location, described by a network address. routing location: routing location of a device is used for routing an emergency call and may not be as precise as the Dispatch Location NOTE: These definitions are a
37、dopted from i.5 - location, as referred to here, normally refer to physical location. User Agent (UA): In SIP a user agent is a set of applications running in the UE (the user equipment) NOTE: This set consists of two units: 1) a user agent client: a caller application that initiates and sends SIP r
38、equests; and 2) a user agent server: an application that receives and responds to SIP requests on behalf of clients, accepts, redirects or refuses calls. Voice Service Provider (VSP): provides a VoIP service Zero-Balance voice service Provider (ZBP): caller has valid credentials with a VSP, but is n
39、ot allowed to place calls, e.g. because the user has a zero balance in a prepaid account 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TS 123 167 i.1, TS 122 101 i.18, TR 121 905 i.19 and the following apply: ANP Access Network Provider CS Circuit Switched DH

44、 subscription is considered. That is: the UE/user is known to a service provider, the subscription account may be zero (Zero-balance Voice Service provider), but the UE can be identified as a valid entity in the network. Emergency call ID/authentication may optionally be based on WLAN/WiFi authentic
45、ation provided by/through the Access Provider (EU regulation, Directive 2006/24/EC i.20, demand all public available communication operators to keep track of and store information about users and their sessions). The following cases/scenarios are identified: 1) Emergency Calls/Sessions in Packet Swi
46、tched Networks. 2) Emergency Calls in Circuit Switched Networks. 3) Emergency Calls/Sessions originated in a PS network, with a PSAP in the CS domain. 4) Emergency Calls originated in a CS network, with a PSAP in the PS domain. 4.1 Emergency Calls/Sessions in Packet (IP) based Networks In this case
47、it is assumed that the SIP protocol forms the basis for signaling (optionally H323), and that the whole session utilize resources in the PS domain. For scenarios see TR 102 476 i.3. The document gives an overview of standardisation activities and summarises different methods for VoIP providers to de

Type of terminals and their capabilities: ETSI ETSI SR 002 777 V1.1.1 (2010-07) 9i) “Softphone“ IP phone realized as an application running on a device with suitable resources (display, keyboard, computing power and connection). ii) “Native“ IP phone (as a sp
49、ecialized physical unit) with suitable display(s), keys, etc. iii) Ordinary telephone handset (or equivalent) with or without a alpha/numerical display connected to IP based service through an adapter. The ANP, ISP and VSP functionality may be realized by different organizations. Operators like Skype, Telio and Vyke, offer Voice over IP services without any contract with the ISPs or ANPs. It can be argued that ETSI may not as an standardisation organisation, provide or specify emergency call functio
