The contents of the present document are subject to contin
39、uing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will 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 pres
40、ented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial on
41、ly changes have been incorporated in the document. ETSI ETSI TS 143 051 V14.0.0 (2017-04)83GPP TS 43.051 version 14.0.0 Release 141 Scope The present document defines the stage 2 service description for a GSM/EDGE Radio Access Network (GERAN). ITU-T Recommendation I.130 describes a three-stage metho
42、d for characterisation of telecommunication services, and CCITT Q.65 defines stage 2 of the method. The present document illustrates how the services requested by a GSM/UMTS Core Network are realized by the GERAN. The main focus of the present document is on functionality related to the Iu interface
43、s. The aim of the present document is not to describe functionality related to the A and Gb interfaces in details. There is no detailed description of the interfaces towards the core network and only references are given to the appropriate specifications. 2 References The following documents contain
44、 provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific
45、reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 2.1 Normative references 1 3GPP TS 25.410: “UTRAN Iu Interfa
