Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee TETRA and Critical Communications Evolution (TCCE). The present document is part 2 of a multi-part deliverable covering TETRA and Critical Communic
26、ations Evolution (TCCE); Critical Communications Architecture, as identified below: TR 103 269-1: “Critical Communications Architecture Reference Model“; TS 103 269-2: “Critical Communications application mobile to network interface architecture“. Modal verbs terminology In the present document “sha
27、ll“, “shall not“, “should“, “should not“, “may“, “may not“, “need“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverabl
28、es except when used in direct citation. ETSI ETSI TS 103 269-2 V1.1.1 (2015-01)81 Scope The present document presents an overview of the architecture for a generic mission critical service for use by a Critical Communications Application in network and terminal over a broadband IP bearer, with speci
29、fic focus for LTE. The architecture is part of the overall Critical Communications Architecture Reference Model, described in ETSI TR 103 269-1 1. The overall architecture and services are described and the implementation of services equivalent to the existing narrowband technologies, for example th
30、ose in TETRA and Tetrapol systems. Off network services are for future study and so are outside the scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
