35、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 will be re-released by the TSG with an identifying change of r

36、elease 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 second digit is incremented for all changes of substance, i.

37、e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 148 016 V14.0.0 (2017-04)73GPP TS 48.016 version 14.0.0 Release 141 Scope The present document specifies the Network Service used on

38、 the Base Station System (BSS) to Serving GPRS Support Node (SGSN) interface (Gb interface). The protocol stack on the Gb interface is defined in the stage 2 Technical Specification 3GPP TS 43.060. The Network Service entity provides network services to the BSSGP entity specified in 3GPP TS 48.018.

39、The layer 1 of the Gb interface is specified in 3GPP TS 48.014. In the present document, the communication between adjacent layers and the services provided by the layers are distributed by use of abstract service primitives. But only externally observable behaviour resulting from the description is

40、 normatively prescribed by the present document. The service primitive model used in the present document is based on the concepts developed in ITU-T Recommendation X.200. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the pres

41、ent 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 reference, the latest version applies. In the case of a reference to a 3GPP document

42、 (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. 1 3GPP TR 21.905: “Vocabulary for 3GPP Specifications“. 2 3GPP TS 22.060: “General Packet Radio Service (GPRS); Service description; Stage 1“. 3
