GW Tester

Summary

This project provides instructions required to setup the demo described by Yoshiyuki Kurauchi in this post.

Concepts

• User Equipment (UE): This is the device that requests connectivity to the network and downloads/uploads any data.
• Evolved UMTS Terrestrial Radio Access Network (E-UTRAN): The network of antennas or Evolved Node B (EnodeB), gives radio access to the UE anywhere there is coverage.
• Public Data Network (PDN): It is a shared network that is accessed by users that belong to different organizations.
• Evolved Packet Core (EPC): It validates the session request from the UE, generates a PDP context and gives access to the PDN.
  • Mobility Management Entity (MME): It does all the signaling for the mobile devices but does not process any user data traffic. An MME will provide session and mobility management for users. In addition, it tracks the location of the UE and selects the S-GW and P-GW that should serve this UE.
  • Serving Gateway (S-GW): In order to eliminate any effect on user data while the UE moves between different eNodeBs, the S-GW works as an anchor point for the user data of the UE, while the UE is moving between different eNodeBs.
  • PDN Gateway (P-GW): This is the node that connects between the LTE network and the PDN.

LTE EPC Network Interfaces

• S1-U: Interface for S1 user plane data for each bearer between the EnodeB and S-GW. Provides non guaranteed data delivery of user plane Protocol Data Units (PDUs).
• S1-MME: Responsible for delivering signaling protocols between the EnodeB and the MME. Consists of a Stream Control Transmission Protocol (SCTP) over IP. The application signaling protocol is an S1-AP (Application Protocol).
• S11: Interface defined between the MME and S-GW for EPS management.
• S5/S8:: Provides user plane tunneling and tunnel management function between the S-GW and P-GW. It enables S-GW to connect to multiple P-GWs for providing different IP services to the UE. Also used for S-GW relocation associated with the UE mobility. In principle S5 and S8 is the same interface, the difference being that S8 is used when roaming between different operators while S5 is network internal.
• SGi: Interface is used between P-GW and intranet or internet.
