What is S8 interface in LTE?
The S8 interface is the roaming variant of S5 and is used in roaming scenarios with the S-GW in the visited network and the P-GW in the home network.
What is S5 S8 in LTE?
S5/S8 This is the interface between the S-GW and P-GW. In principle S5 and S8 is the same interface, the difference being that S8 is used when roaming between different operators while S5 is network internal. The S5/S8 interface is used within the Evolved Packet Core (EPC) for LTE.

What is S11 interface in LTE?
S11 This is the interface between the MME and S-GW in an LTE network. The interface is based on Gn/GTP-Control (GTP-C) (interface between SGSN-GGSN) with some additional functions for paging coordination, mobility compared to the legacy Gn/GTP-C (SGSN-GGSN) interface. S11 is a many-to-many interface.
What is an LTE interface?
Within an LTE network, LTE Interfaces connect the various components to or within the core. Interfaces allow the MME, SGW and PGW to cooperate with other network elements (e.g. HSS or PCRF). Each one of them is built in a standard way described by 3GPP.org.

What is S7 interface in LTE?
Interface: S7 Protocol Used: Gx. Description: It provides transfer of QoS service and charging rules from Policy and PCRF to Policy and Charging Enforcement Function (PCEF) in PDN-GW
What is S9 interface in LTE?
S9:- It provides transfer of (QoS) policy and charging control information between the Home PCRF and the Visited PCRF in order to support local breakout function. S10:- Reference point between MMEs for MME relocation and MME to MME information transfer.
What is S4 interface in LTE?

What is S1-MME interface in LTE?
S10 This is a control interface between the MMEs which will be very similar to the S3 interface between the SGSN and MME. The interface is based on Gn/GTP-C (SGSNSGSN) with additional functionality. S10 is a many-to-many interface. The S10 interface is used within the Evolved Packet Core (EPC) for LTE.
Why are we using S1 interface?
The LTE S1-MME interface is responsible for delivering signaling protocols between the eNodeB and the MME. S1-MME interface consists of a Stream Control Transmission Protocol (SCTP) over IP and supports multiple UEs through a single SCTP association. It also provides guaranteed data delivery.
What network element is LTE?
It is only composed of one network element: the eNodeB (for evolved Node B.). The 3G RNC (Radio Network Controller) inherited from the 2G BSC (Base Station Controller) has disappeared from E-UTRAN and the eNodeB is directly connected to the Core Network using the S1 interface.
What is LTE network and how does it work?
LTE moves large packets of data to an internet protocol system (IPS). Old ways of moving data used Code-division multiple access (CDMA) and the Global System for Mobile Communications (GSM), and those methods moved only small amounts of data. LTE can handle much more data transfer, and it helps streamline your service.
What are the components of LTE?
The high-level network architecture of LTE is comprised of the following three main components:
- The User Equipment (UE).
- The Evolved UMTS Terrestrial Radio Access Network (E-UTRAN).
- The Evolved Packet Core (EPC).
What is the function of LTE?
In telecommunications, Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards’ capacity and speed by using a different radio interface and core network improvements.
What is S11 in LTE?
The S8 interface is the roaming variant of S5 and is used in roaming scenarios with the S-GW in the visited network and the P-GW in the home network.
What is S1 interface in LTE?
The interfacebetween SGSN and the serving gateway is referred as S4 interface. It provides user plane support for mobility support between the GPRS core and the serving gateway. It also enables the serving gateway to anchor the inter-3GPP handover. S5.
What are LTE network elements?
LTE S1-UP (user plane) The S1 user plane external interface (S1-U) is defined between the LTE eNodeB and the LTE S-GW. The S1-U interface provides nonguaranteed data delivery of LTE user plane Protocol Data Units (PDUs) between the eNodeB and the S-GW. The transport network layer is built on IP transport and GTP-U.
What is the difference between S5 and S8 interfaces in LTE?

What is S5 interface?
The S8 interface is the roaming variant of S5 and is used in roaming scenarios with the S-GW in the visited network and the P-GW in the home network.
What is S9 interface?
In wireless applications, the S9 interface is a 4G interface between the Visiting PCRF and Home PCRF.

What is Gx and Gy interface?
Gx interface enables signaling of PCC decisions, negotiation of IP-CAN bearer establishment mode and termination of Gx session. Gy. It is the online charging reference point. Gy lies between PCEF (Policy Control Enforcement Function) and OCS (Online Charging Function).
What is S6b interface used for?
The S6b interface is used to inform the 3GPP AAA server/proxy about current PDN GW identity and the APN being used for a given UE, or that a certain PDN GW and APN pair is no longer used. This occurs, for example, when a PDN connection is established or closed.
