Foreword This Technical Specification (TS) has
23、 been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 4 of a multi-part deliverable covering GNSS-based Location Systems (GBLS), as identified below: Part 1: Functional requirements; Part 2: Reference Architecture; Part 3: Performance req
24、uirements; Part 4: Requirements for location data exchange protocols; Part 5: Performance Test Specification. Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in
25、clause 3.2 of the ETSI 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
26、and devices; these include 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 ar
27、e designed to deliver location-related information for one or more targets to user applications. The wide spectrum of technical features identified in ETSI TR 103 183 i.1 calls for a new and broader concept for location systems, taking into account hybrid solutions in which GNSS technologies are com
28、plemented with other technology sensors to improve robustness and the performance. ETSI ETSI TS 103 246-4 V1.1.1 (2016-01)6 1 Scope The present document defines the requirements for data elements that may need to be exchanged within the GBLS and externally to applications using the GBLS. The present
29、 document also specifies data exchange models for these data elements which may form the basis of protocols (or for modification of protocols) and which may be used for the exchange of location-related data within the GNSS-based Location System (GBLS), as well as between the GBLS and external applic
30、ations. In particular, the present document defines the procedures and messages associated with these data exchange models The GBLS data exchange models are defined to be independent of their underlying transport mechanisms. Nevertheless, on certain GBLS interfaces, transport protocols are recommend

48、e GBLS; and 2) internally between modules of the GBLS. The specific requirements for this data are defined further in clauses 5 and 6. In addition, data exchange models are defined herein as a basis for protocols that may be used to transfer the GBLS data. Figure 4.1 shows these defined protocol mod
49、els and their relevant interfaces applied to the GNSS-based Location System (GBLS) and its functional entities as defined in ETSI TS 103 246-2 2, within an end-to-end system. NOTE: Throughout the present document, the word “protocol“ is used for brevity, when defining a GBLS “data exchange model“. The specifications herein are of data exchange models that may form the basis of protocols.
