Introduction
This document describes how to implement the change(s) specified for Circuit Switch Fall Back (CSFB)
activation in order to allow the voice and Short Messaging Service (SMS) with Mobile Switching Center
(MSC)/Visitor Location Registry (VLR) over a subscriber group (SG) interface. The SG interface is between
Mobility Management Entity (MME) in the Evolved Packet System (EPS) and the VLR, in order to allow
location management coordination and in order to relay certain messages related to circuit switched services
over the EPS system.
