LTE components

What is what in the following diagram when it comes to LTE components
eNodeB -Evolved Node B
This is the main component that allows users to connect to the network.

MME – Mobility Management Entity.
The MME is responsible for initiating paging and authentication of the mobile device. MME retains location information at the tracking area level for each user and then selects the appropriate gateway during the initial registration process.

S-GW-Serving Gateway
The S-GW is responsible for keeping track of devices when they move between eNobeB’s. This is typically not an extra piece of hardware just a function of the EPC

P-GW
This is what connects the LTE network to the Capital I Internet. This also is typically not an extra piece of hardware just a function of the EPC

 

Other terms
The S1 interface is described in the 3GPP TS 36.410 specification.

The X2 interface provides connectivity between two or more eNodeBs.
