Lte Core Network Component Diagram

The long term evolution standard lte is a wireless communications high speed data standard for mobile phones and data terminals.

Lte core network component diagram. The lte network called eps evolved packet system is an end to end e2e all ip network. However only the master lte node has a control plane connection to the mme. Eps is divided into two parts lte part which deals with the technology related to a radio access network e utran and epc part which deals with the technology related to a core network. The high level network architecture of lte is comprised of following three main components.

Cloud native new core architecture 4 1 control and user plane separation simplifies the core network 4 2 flexible network components satisfy various service requirements 4 3 unified database management self service agile operation conclusion. In this diagram the lte node serves as the master menb and the 5g node serves as the secondary en gnb. The e utran the access network the architecture of evolved umts terrestrial radio access network e utran has been illustrated below. The components of the nss include the mobile.

This keeps information about the user s phone number home network identity and security keys etc. A usim stores user specific data very similar to 3g sim card. Support for and mobility between multiple heterogeneous access networks. Lte control plane vs.

The figure below describes the lte umts overall network architecture not only including the evolved packet core epc and evolved umts terrestrial access network e utran but also other components in order to show the relationship between them. All ip network aipn support for higher throughput and lower latency radio access networks rans. Cloud native architecture is the foundation of 5g innovation 04 05 08 09 13 17 19. This document presents the lte network architecture as the first technical document of lte area.

Hss refers to home subscriber server. The e utran handles the radio communications between the mobile and the evolved packet core and just has one component the evolved base stations called enodeb or enb. A generalized diagram of 5g nsa is shown below. Pdn refers to public data network and it is the network that the ue would like to connect to.

The hss is the database that stores the subscription information of the users in the network like which pdn they should be able to access and the qos they should have. System architecture evolution sae is the core network architecture of 3gpp s lte wireless communication standard. Its basis stands in the gsm edge and umts hspa network technologies with changes in terms of an increased capacity and higher speed by simplifying the core network and using a different radio interface. The master lte and secondary 5g node both have direct interface with the evolved packet core s gw p gw.

Network and switching subsytem nss the nss is the core component of the gsm architecture which is responsible for call switching end to end calls mobility management of subscribers and communication with other networks such as pstn and isdn.
