41、14Foreword This Technical Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it w
42、ill be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the
43、 second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The present document specifies minimum performance requirements for the
44、 acoustic characteristics of 3G and LTE terminals when used to provide narrowband, wideband, super-wideband or fullband telephony. The objective for narrowband services is to reach a quality as close as possible to ITU-T standards for PSTN circuits. However, due to technical and economic factors, th
45、ere cannot be full compliance with the general characteristics of international telephone connections and circuits recommended by the ITU-T. The performance requirements are specified in the main body of the text; the test methods and considerations are described in TS 26.132. ETSI ETSI TS 126 131 V
46、14.0.0 (2017-04)83GPP TS 26.131 version 14.0.0 Release 141 Scope The present document is applicable to any terminal capable of supporting narrowband, wideband, super-wideband or fullband telephony, either as a stand-alone service or as the telephony component of a multimedia service. The present doc
47、ument specifies minimum performance requirements for the acoustic characteristics of 3G and LTE terminals when used to provide narrowband, wideband, super-wideband or fullband telephony. The set of minimum performance requirements enables a guaranteed level of speech quality while taking possible ph
48、ysical limits of the terminal design into account. Some performance objectives are also defined, if such design limits can be overcome. Care must be taken in applying performance objectives in isolation, not to degrade overall end-user speech quality. 2 References The following documents contain pro
