What is SGi interface?
What is SGi interface?
The SGi interface is defined by the 3GPP as the interface between the Evolved Packet Core (EPC) and the Public IP network. Importantly, traffic through the interface can be identified by user IP, making user and service differentiation a reality.
What is IMS and EPC?
IMS – IP Multimedia Subsystem is a standalone system. It resides out of the LTE network and connected to PDN Gateway through SGi interface. The EPC has three main functional elements. The first one is Mobility Management Entity (MME). The last in the list is P-GW or PDN Gateway.
What is IMS in LTE?
The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is a standardised architectural framework for delivering IP multimedia services. Historically, mobile phones have provided voice call services over a circuit-switched-style network, rather than strictly over an IP packet-switched network.
What is 3GPP interface?
The 3rd Generation Partnership Project (3GPP) is an umbrella term for a number of standards organizations which develop protocols for mobile telecommunications. GSM and related 2G and 2.5G standards, including GPRS and EDGE. UMTS and related 3G standards, including HSPA and HSPA+
What does the S12 interface allow to happen?
S6a:- It enables transfer of subscription and authentication data for authenticating/authorizing user access to the evolved system (AAA interface) between MME and HSS. S12:- Reference point between UTRAN and Serving GW for user plane tunnelling when Direct Tunnel is established.
Who made 5G technology?
Low-band 5G uses a similar frequency range to 4G cellphones, 600–850 MHz, giving download speeds a little higher than 4G: 30–250 megabits per second (Mbit/s)….This article’s lead section may be too long for the length of the article.

What is RF interface?
The Rf interface is the offline charging interface between the Charging Trigger Function (CTF) (for example, P-GW, P-CSCF) and the Charging Collection Function (CCF). The Rf interface specification for LTE/GPRS/eHRPD offline charging is based on 3GPP TS 32.299 V8. 6.0, 3GPP TS 32.251 V8.
Which is interface between PGW and IMS network?
SGi : This SGi interface is used between PGw towards internet or IMS Network. This is highway for Exit traffic from LTE Network SGs Link – LTE Protocols & Links SGs Link – LTE Protocols & Links
What is the SGS interface used for in LTE?
SGs : The SGs interface is used for connectivity between LTE MME to 2G (GERAN) / 3G (UTRAN) MSCs . Prior to VoLTE launch , This link was playing critical role in 4G Network by enabling voice via CSFB function & also enabled SMS as well This diagram shows LTE Network Architecture & Links used in 4G network .
Which is part of the IMS IP subsystem?
IMS – IP Multimedia Subsystem is a standalone system. It resides out of the LTE network and connected to PDN Gateway through SGi interface. The EPC has three main functional elements. The first one is Mobility Management Entity (MME).
Which is part of the IMS VoLTE architecture?
IMS VoLTE Architecture The idea of IMS is old, but after it’s deployment with LTE users and operators can harness the true power of IMS. IMS – IP Multimedia Subsystem is a standalone system. It resides out of the LTE network and connected to PDN Gateway through SGi interface.
