E-UTRAN is the combination of E-UTRA, user equipment (UE), and a Node B (E-UTRAN Node B or Evolved Node B, eNodeB). It is a radio access network (RAN) meant to be a replacement of the Universal Mobile Telecommunications System (UMTS), High-Speed Downlink Packet Access (HSDPA), and High-Speed Uplink Packet Access (HSUPA) technologies specified ...

2019年11月24日 · The LTE radio access network is called Evolved UMTS Terrestrial Radio Access Network or E-UTRAN. As part of E-UTRAN, eNodeB connects directly to the 4G core network components, MME (Mobility Management Entity) and Serving Gateway (S-GW).

The architecture of evolved UMTS Terrestrial Radio Access Network (E-UTRAN) has been illustrated below. The E-UTRAN handles the radio communications between the mobile and the evolved packet core and just has one component, the …

2023年3月30日 · The Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) is a wireless communication technology standard that is designed to provide high-speed mobile data services to cellular devices. E-UTRAN is a key component of the Long Term Evolution (LTE) network, which is the latest wireless communication standard used by mobile network operators

(Evolved-UMTS Terrestrial Radio Access Network) E-UTRAN is the air interface in an LTE cellular network. Officially, E-UTRAN governs the base station, while E-UTRA (without the "N") defines...

2024年1月18日 · LTE E-UTRAN plays a central role in the LTE architecture, providing the radio access network for efficient and high-performance wireless communication. It encompasses the eNodeB, UEs, and critical protocols that enable the establishment of connections, mobility management, and the reliable transmission of data between mobile devices and the LTE ...

E-UTRAN Architecture. In order to meet the requirements for LTE networks, the evolved UTRAN (E-UTRAN) architecture has been improved dramatically from the 3G/3.5G radio access network (UTRAN). While legacy networks employed a hierarchical architecture, E-UTRAN uses a …

The Access Network of LTE, known as E-UTRAN, is composed of a network of eNodeBs, which manage normal user traffic without a centralized controller, leading to a flat network architecture. eNodeBs are interconnected through the X2 interface and connected to the EPC via the S1 interface, specifically using the S1-MME interface for the MME and ...

The Evolved UMTS Terrestrial Radio Access Network (E-UTRAN), the very first network node in the evolved packet system (EPS), achieves high data rates, lower control & user plane latency, seamless handovers, and greater cell coverage.

The present document describes the overall architecture of the E-UTRAN, including internal interfaces and assumptions on the radio, S1 and X2 interfaces. The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
