Foreword This Technical Sp
14、ecification (TS) has been produced by ETSI Technical Committee Mobile Standards Group (MSG). The present document is part 2 of a multi-part deliverable covering eCall Network Access Device (NAD) conformance specification as identified below: Part 1: “Protocol test specification“; Part 2: “Test suite
15、s“. The present document may refer to technical specifications or reports using their 3GPP identities, UMTS identities or GSM identities. These should be interpreted as being references to the corresponding ETSI deliverables. The cross reference between GSM, UMTS, 3GPP and ETSI identities can be fou
16、nd under http:/webapp.etsi.org/key/queryform.asp . Introduction Following a decision of the European Parliament, and a request by the European Commission to ETSI, ETSI TC MSG was tasked with managing the technical specification and creation of open standards for the Pan-European eCall emergency serv
17、ice. An eCall is an emergency voice call, initiated manually or automatically from a vehicle to a Public Safety Answering Point (PSAP), supplemented by up to 140 bytes of incident related data. The Minimum Set of Data (MSD) has been defined by CEN Technical Committee 278 and includes the GNSS derive
18、d location and direction of travel of the vehicle, the Vehicle Identification Number (VIN) and other information to enable the emergency response teams to quickly location and provide medical and other life saving assistance to the accident victims. eCall has been designed to operate over any PLMN t
19、hat supports emergency voice calls, specifically TeleService 12. Should the MSD not be transmitted or received for any reason, or if the PSAP is not equipped with the necessary eCall equipment (eCall modem / server), the accident victims and PSAP operator may still converse using the In-Vehicle Syst
20、em (IVS) audio equipment. The 3rdGeneration Partnership Project (3GPP) has specified the eCall service requirements, data transmission protocols and network signaling aspects for Release 8. NOTE: Early implementation of eCall in Release-7 is certifiable. The in-band modem used to transfer the MSD fr
21、om the vehicle to the PSAP, following the establishment of a 112 or other emergency voice call, has been specified by 3GPP TSG SA4. Once an eCall is invoked - initiated manually by the vehicle occupants or automatically as the result of an accident, the eCall call set-up and clear-down procedures (R
22、R, CC, and MM) are automatically controlled by the eCall in-vehicle system (IVS) and network access device (NAD). Once initiated the system requires no MMI intervention and does not permit the user to intervene at any stage during call management. It is important, therefore, that the eCall system wo
23、rks autonomously and reliable when faced with a wide range of probable network access events. ETSI ETSI TS 102 936-2 V1.1.1 (2011-04)5An eCall NAD may be used to access other non-emergency subscription services or for the purpose of making emergency calls only. In the latter case the eCall NAD is re
24、ferred to an eCall only device and there are specific network access restrictions placed on these devices in order to avoid the generation of large volumes of unnecessary MM signaling, when not engaged in an eCall, test or reconfiguration call TS 122 101 1. The eCall NAD is permitted to make calls t
25、o a non-emergency number for the purpose of testing, or requesting the reconfiguration of the NAD to lift the network access restriction so as to allow the NAD to register on power-up and to access subscribed to commercial services. The eCall in-band modem conformance test protocols are as specified
26、 in TS 126 269 2. A vademecum on the applicability of ETSI GSM and UMTS mobile station harmonised standards EN 301 908 parts 1 7 and 2 8 and EN 301 511 9 to the ETSI specified eCall NAD, for the purpose of demonstrating compliance with R - the test methods and PCO definitions; - the test configurati

43、for the development and production of TTCN specification for 3GPP UE at Uu interface. 1. Top-down design, following TS 134 123-1 4, TS 134 108 6 and TS 134 109 3. 2. A unique testing architecture and test method for testing all protocol layers of UE. 3. Uniform TTCN style and naming conventions. 4.
44、Improve TTCN readability. 5. Using TTCN-2+ (TR 101 666 i.3) avoid the use of the TTCN 2 features TTCN 3 does not support. 6. TTCN specification feasible, implementable and compilable. 7. Test cases shall be designed in a way for easily adaptable, upwards compatible with the evolution of the 3GPP cor
45、e specifications and the future Releases. 8. The test declarations, data structures and data values shall be largely reusable. 9. Modularity and modular working method. 10. NAS ATS should be designed being independent from the radio access technologies. 11. Minimizing the requirements of intelligenc
46、e on the emulators of the lower testers. Especially the functionality of the RRC emulator in the TTCN tester should be reduced and simplified, the behaviours should be standardized as the TTCN RRC test steps in the TTCN modular library. 12. Giving enough design freedom to the test equipment manufact
47、urers. 13. Maximizing reuse of ASN.1 definitions from the relevant core specifications. In order to fulfil these requirements and to ensure the investment of the test equipment manufacturers having a stable testing architecture for a relatively long period, a unique testing architecture and test met
48、hod are applied to the 3GPP UE protocol tests. 5 ATS structure - Modularity The eCall ATS is developed making use of the modular TTCN approach used for the development of the 3GPP ATS specifications. The following modules are used: BasicM, RRC_M, L3M, NAS_M, HSR5_R6_M, R7_M and R8_M. The module stru
49、cture is shown in figure 1.
