Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 2 of

20、Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction The increasing proliferation of location-based services is based on several trends in user applications and devices; these incl

21、ude notably the widespread adoption of multi-functional smart-phones etc., and the wider adoption of tracking devices (e.g. in transport). This need for new and innovative location-based services is generating a need for increasingly complex location systems. These systems are designed to deliver lo

22、cation-related information for one or more location targets to user applications. The wide spectrum of technical features identified in i.1 calls for a new and broader concept for location systems, taking into account hybrid solutions in which GNSS technologies are complemented with other technology

23、 sensors to improve robustness and the performance. Hence a set of standards for GNSS-based Location systems is defined of which the present document is part 2. ETSI ETSI TS 103 246-2 V1.1.1 (2015-04)6 1 Scope The present document addresses generic architectures for GNSS-based Location Systems (GBLS

24、s) that combine Global Navigation Satellite Systems (GNSS - e.g. Galileo) and other navigation technologies with telecommunication networks for delivery of location-based services. The architecture specified herein is a “functional“ architecture, meaning that the system is defined in terms of discre

25、te functional elements connected to other internal or external functional elements via associated “logical“ interfaces. These functional elements and interfaces are derived from service requirements. The functional architecture is not necessarily related to the “physical architecture“ (i.e. the rela

26、tionship between equipment which may implement all or some of these functions, and the physical interfaces between them). The present document can be considered as the Stage 2 functional specification according to the ITU/3GPP approach i.4. 2 References 2.1 Normative references References are either

Thesis, Department of Geomatics Engineering, Calgary, Alberta(CAN), September 2005. 3 Definitions, symbols and abbreviations 3.1 Definitions For the purposes of the present document,

38、the following terms and definitions apply: authentication: provision of assurance that the location related data associated with a location target has been derived from real signals associated with the location target NOTE: Authentication is one of the key performance features that may be required o

39、f a location system. architecture: abstract representation of a communication system NOTE: Three complementary types of architecture are defined: square4 Functional Architecture: the discrete functional elements of the system and the associated logical interfaces. square4 Physical (Network) Architec

40、ture: the discrete physical (network) elements of the system and the associated physical interfaces. square4 Protocol Architecture: the protocol stacks involved in the operation of the system and the associated peer relationships. availability: measures percentage of time that a location system is a

41、ble to provide the required location-related data NOTE 1: The required location-related data might vary between location based applications. NOTE 2: It may contain more than a required information type (e.g. position and speed), but also a required quality of service (e.g. accuracy, protection level

42、, authentication). continuity: likelihood that the navigation signal-in-space supports the accuracy and integrity requirements for the duration of the intended operation ETSI ETSI TS 103 246-2 V1.1.1 (2015-04)8 NOTE: It guarantees that a user can start an operation during a given exposure period wit

43、hout an interruption of this operation, assuming that the service was available at beginning of the operation. Conversely, a Loss of Continuity occurs when the user is forced to abort an operation during a specified time interval after it has begun (the system predicts service was available at start

44、 of operation). continuity risk: probability of a detected but unscheduled navigation interruption after initiation of an operation electromagnetic interference: any source of RF transmission that is within the frequency band used by a communication link, which degrades the performance of this link

45、NOTE: Jamming is a particular case of electromagnetic interference, where an interfering radio signal is deliberately broadcast to disrupt the communication. integrity: function of a location system that measures the trust that can be placed in the accuracy of the location-related data provided by t

46、he location system NOTE: In the present technical context, it is expressed through the computation of a protection level. The Integrity function includes the ability of the location system to provide timely and valid warnings to users when the system should not be used for the intended operation. Sp

47、ecifically, a location system is required to deliver a warning (an alert) of any malfunction (as a result of an alert limit being exceeded) to users within a given period of time (time-to-alert). Conversely, a Loss of Integrity event occurs when an unsafe condition occurs without annunciation for a

48、time longer than the time-to-alert limit. integrity risk: probability that the actual error of the location-related data is larger than the protection level, in case of system availability (i.e. protection level lower than the alert limit) jamming: deliberate transmission of interference to disrupt

49、reception of desired signals, which in this case are GNSS or telecommunication signals NOTE: Spoofing is considered to be a deceptive form of jamming. latency: measure in a location system of the time elapsed between the event triggering the determination of the location-related data for one or more location targets (i.e. a location request from an external client, an external or internal event triggering location reporting), and the availability of the location-related data at the user interface location-based application: application for
