![]() ![]() When UE switches on, it sends an Initial UE message with Attach request for PDN connectivity to the MME. Here we will describe the initial attach procedure to understand the basic functionality of the MME in the LTE network. Till now we have described key Interfaces of MME. The T6a interface is a diameter protocol interface with the SCEF for the Non-IP data delivery in the IoT network. The HSS may be co-located with the AUC for the 4G authentication. It is the node that holds the subscription data for a subscriber. The eNodeB sends user data packets to the SGW using the GTP-U data plane protocol. During attach and other activities via UE, SGW does signaling with the PGW in-home network over the s5/S8 interface. The S11 interface is a GTP-C-V2 (Version 2) based Interface with the SGW.
