LTE_EPC_Introduction.ppt................
The document provides an introduction to LTE (Long Term Evolution) and EPC (Evolved Packet Core) architecture, covering essential components and functionalities of each node in the network. It outlines the learning objectives, including the description of LTE/EPC architecture, nodes, interfaces, and interconnections with other networks. Additional resources for in-depth training are mentioned for further exploration of the subject.

- #12 In E-UTRAN, the e-NodeB is realized by the Ericsson product called RBS6000. There are several models of RBS6000, like macro-, main-remote and pico-basestations.
- #13 In EPC, The MME is realized by our product called SGSN-MME , which also include the GPRS Packet Core node SGSN. The PCRF is realized by our product SAPC (Service Aware Policy Controller), which is based on the TSP6 platform Our HSS product is based on the same platform as the SAPC, i.e. TSP6. Both P-GW and S-GW are realized by the Ericsson Product Evolved Packet Gateway (EPG)
- #14 Here we see a typical implementation of LTE/EPC together with GERAN and UTRAN. The SGSN is needed for GERAN connectivity to/from GPRS Packet Core. UTRAN uses 3G Direct Tunnel, which means that the SGSN is bypassed and the user data goes directly to/from the PDN-GW. Therefore, only the SGSN-MME and the EPG is needed for the basic user plane functionality in EPC to support GERAN, UTRAN and E-UTRAN radio access networks.
- #15 The connections between the nodes in E-UTRAN, EPC, IMS other networks (e.g UTRAN, GERAN, GPRS Packet Core and WiFi) are managed by our product called Evolved IP Network (EIN). EIN provides end-to-end solutions attribues for Network Management, Performance Management, QoS, Security and Synchronization between the nodes.
