42、hnical Specification (TS) has been produced by the 3rdGeneration Partnership Project (3GPP). The present document specifies procedures used between the Serving GPRS Support Node (SGSN) and the Visitors Location Register (VLR) for co-ordination between GSM circuit switched services and GSM packet dat
43、a services within the 3GPP system. 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 release date
44、 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.e. technica
45、l 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 or references the procedures to provide co-ordination between the GSM circuit switched services controlled at th
46、e Visitors Location Register (VLR) and the GSM packet switched services controlled at the Serving GPRS Support Node (SGSN). The procedures specified in the present document are intended to optimise the use of the resources when an MS supports both GSM circuit switched services and GSM packet switche
47、d services. ETSI ETSI TS 129 018 V14.0.0 (2017-04)83GPP TS 29.018 version 14.0.0 Release 141 Scope The present document specifies or references procedures used on the Serving GPRS Support Node (SGSN) to Visitors Location Register (VLR) interface for interoperability between GSM circuit switched serv
48、ices and GSM packet data services. The present document specifies the layer 3 messages and procedures on the Gs interface to allow coordination between databases and to relay certain messages related to GSM circuit switched services over the GPRS subsystem. The functional split between VLR and SGSN
49、is defined in 3GPP TS 23.060 8. The required procedures between VLR and SGSN are defined in detail in the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
