The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: “Int
26、ellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http:/ipr.etsi.org). Pursuant to the ETSI IPR Policy, no investigation, inclu
27、ding IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This ETSI Standard (ES) has been pro
28、duced by ETSI Technical Committee Methods for Testing and Specification (MTS). The use of underline (additional text) and strike through (deleted text) highlights the differences between base document and extended documents. The present document relates to the multi-part standard ETSI ES 201 873 cov
29、ering the Testing and Test Control Notation version 3, as identified below: Part 1: “TTCN-3 Core Language“; Part 4: “TTCN-3 Operational Semantics“; Part 5: “TTCN-3 Runtime Interface (TRI)“; Part 6: “TTCN-3 Control Interface (TCI)“; Part 7: “Using ASN.1 with TTCN-3“; Part 8: “The IDL to TTCN-3 Mappin
30、g“; Part 9: “Using XML schema with TTCN-3“; Part 10: “TTCN-3 Documentation Comment 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 clause 3.2
31、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. ETSI ETSI ES 202 786 V1.3.1 (2015-06) 6 1 Scope The present document defines the “Continuous Signal support“ package of TTCN-3.
32、TTCN-3 can be used for the specification of all types of reactive system tests over a variety of communication ports. Typical areas of application are protocol testing (including mobile and Internet protocols), service testing (including supplementary services), module testing, testing of CORBA base
33、d platforms, APIs, etc. TTCN-3 is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustness, regression, system and integration testing. The specification of test suites for physical layer protocols is outside the scope of the presen
34、t document. TTCN-3 packages are intended to define additional TTCN-3 concepts, which are not mandatory as concepts in the TTCN-3 core language, but which are optional as part of a package which is suited for dedicated applications and/or usages of TTCN-3. This package defines concepts for testing sy
35、stems using continuous signals as opposed to discrete messages and the characterization of the progression of such signals by use of streams. For both the production as well as the evaluation of continuous signals the concept of mode is introduced. Also, the signals can be processed as history-trace
36、s. Finally, basic mathematical functions that are useful for analyzing such traces are defined for TTCN-3. It is thus especially useful for testing systems which communicate with the physical world via sensors and actuators. While the design of TTCN-3 package has taken into account the consistency o
37、f a combined usage of the core language with a number of packages, the concrete usages of and guidelines for this package in combination with other packages is outside the scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publi
