47、t. Introduction The present document specifies or references the procedures to provide co-ordination between the GSM circuit switched services controlled at the Visitors Location Register (VLR) and the GSM packet switched services controlled at the Serving GPRS Support Node (SGSN). The procedures sp
48、ecified 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 switched services. ETSI ETSI TS 129 018 V15.0.0 (2018-06)83GPP TS 29.018 version 15.0.0 Release 151 Scope The present document specifies or referenc
49、es procedures used on the Serving GPRS Support Node (SGSN) to Visitors Location Register (VLR) interface for interoperability between GSM circuit switched services 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 is defined in 3GPP TS 23.060 8. The required procedures between VLR and SGSN are defined in detail in the present document
