The Access Network The access network of LTE, E-UTRAN, simply consists of a network of eNodeBs,For normal user traffic (as opposed to broadcast), thereis no centralized controller inE-UTRAN; hence the E-UTRAN architecture is said to be flat. The eNodeBs are normally interconnected with ...
This document presents the LTE network architecture as the first technical document of “LTE” area. The LTE network called EPS (Evolved Packet System) is an end-to-end (E2E) all IP network; EPS is divided into two parts - LTE part which deals with the technology related to a radio acce...
Below is a brief description of each of the components shown in the above architecture:The Home Subscriber Server (HSS) component has been carried forward from UMTS and GSM and is a central database that contains information about all the network operator's subscribers. The Packet Data Network ...
01-00-LTE Network Architecture Basic[中文翻译] I. Introduction 这篇文章主要介绍LTE网络结构,是LTE的第一篇技术文章。LTE网络也叫EPS,是一个端到端的全IP网络;EPS分为两个部分,LTE部分负责处理和接入网络E-UTRAN相关的技术,EPC部分负责处理和核心网相关的技术。一个端到端的全IP网络意味着:所有的数据流,从...
PDN (Packet Data Network) You can think of it as the Internet. For now, let's just say PDN = Internet = IP Network. For more details about LTE network architecture, see Netmanias technical document, "LTE Network Architecture: Basic"...
包数据网络网关PGW(The Packet Data Network Gateway)为用户终端UE(User Equipment)和外部PDN网络提供连接,UE和外部PDN网络的数据需要经过PGW。 Serving Gateway 服务网关。 服务网关SGW(Serving Gateway)对报文进行路由和转发,它对用户层面的移动性进行管理,同时也对LTE和其他3GPP技术之间的移动性进行管理。 SGSN GPRS服...
DN: 数据网络Data Network (DN), 比如运营商业务,互联网接入或者第三方业务等。 UDFS: 非结构性数据存储功能Unstructured Data Storage Function NEF: 网络业务呈现功能Network Exposure Function (NEF) NRF: 网元数据仓库功能NF Repository Function (NRF)

IMSI存储在一个HSS和一个SPR中,也就是LTE实体。在HSS中,存储了一个密钥,与IMSI一起用于用户的身份验证,以及用户使用的QoS配置文件。因此,当用户尝试访问时(即谁发送了Attach Request消息),HSS(MME代表HSS,要准确。见LTE身份验证的进一步解释)拒绝未注册的IMSI用户,但允许拥有有效注册的IMSI的用户通过发送 运营商...
