What is LTE UE?

What is LTE UE?

In the Universal Mobile Telecommunications System (UMTS) and 3GPP Long Term Evolution (LTE), user equipment (UE) is any device used directly by an end-user to communicate. It roughly corresponds to the mobile station (MS) in GSM systems. The radio interface between the UE and the Node B is called Uu.

What is LTE stack protocol?

The protocol stack functions consist of the Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC). LTE is the latest generation of the 3GPP standards. The LTE standard specifies an IP-only network supporting data rates up to 150 Mbps.

What is UE in LTE architecture?

The high-level network architecture of LTE is comprised of following three main components: The User Equipment (UE). The Evolved UMTS Terrestrial Radio Access Network (E-UTRAN). The Evolved Packet Core (EPC).

What are the protocols used in LTE?

LTE Protocols

  • Air Interface Physical Layer.
  • GPRS Tunnelling Protocol User Plane (GTP-U)
  • GTP-U Transport.
  • Medium Access Control (MAC)
  • Non-Access-Stratum (NAS) Protocol.
  • Packet Data Convergence Protocol (PDCP)
  • Radio Link Control (RLC)
  • Radio Resource Control (RRC)

How does LTE work?

How does LTE work? LTE changes the current method of moving data to an internet protocol system. Rather than move small amounts of data, as both CDMA and GSM do, it will move large packets of data and streamline the service. The major benefit to LTE is that in reduces the latency in data transfer.

What LTE means?

Long Term Evolution
Verizon 4G LTE explained LTE stands for Long Term Evolution. It’s a term used for the particular type of 4G that delivers the fastest mobile Internet experience. Using a 4G smartphone on Verizon’s 4G LTE network means you can download files from the Internet up to 10 times faster than with 3G.

What OSI layer is LTE?

layer 2
This chapter discusses a long term evolution (LTE) air interface by describing three protocols in a data link layer, layer 2 of the OSI model. The medium access control (MAC) protocol schedules all the transmissions that are made on the LTE air interface and controls the low-level operation of the physical layer.

What is LTE call flow?

With Long Term Evolution (LTE) comes a myriad of new and exciting attributes. One of these is the LTE call flow itself. In fact, call flow and signaling is unique for LTE, and is driven by 3GPP standards. Call flow is how signaling and sessions are created across an LTE network.

What are the advantages of LTE?

Compared with previous mobile network technologies, 4G LTE offers much higher bandwidth (speed of data transfer), lower latency (faster response times from the network) and improved spectrum efficiency (increasing overall network capacity).

Does LTE use TCP?

Abstract. One of the implementation of a wireless network is based on mobile broadband technology Long Term Evolution (LTE). The majority of the Internet connections in the world happen using the TCP (Transmission Control Protocol) due to the TCP’s reliability in transmitting packets in the network.

Is there a UE side LTE protocol stack?

It provide very detail of LTE protocol stacks on UE side. Thanks for sharing it. Great Document and easiest visualisation of protocol stack. Thanks a lot Thanks a lot. Great description !!

What are the protocols and specifications of LTE?

LTE Protocols & Specifications In LTE architecture, core network includes Mobility Management Entity (MME), Serving Gateway (SGW), Packet Data Network Gateway (PDN GW) where as E-UTRAN has E-UTRAN NodeB (eNB).

What is the protocol structure between UE and Mme?

Protocol structure of control plane in between UE & MME is shown below. This figure below shows protocol structure in between UE & P-GW user plane. GPRS Tunnelling Protocol for the user plane (GTP-U) tunnels user data between eNodeB and the S-GW as well as between the S-GW and the P-GW in the backbone network.

What is the user control plane in LTE?

The user plane LTE protocol stack consists of upper layers, NAS, PDCP, RLC, MAC, PHY and RF. The functions of each are outlined below: The modules are depicted in the figure on right side.
