4G EPS Architecture-Mobility Management Entity (MME)

Hello friends, here is the link to my new UDEMY Course on 4G LTE: Technology, Architecture And Protocols, and all other courses

The EPC represents the Core of an LTE network. It is formed by multiple nodes, the main ones being MME, SGW, PGW and HSS. This nodes offer multiple functionality like mobility management, authentication, session management, setting up bearers and application of different Quality of Services.
The MME is located at the edge of LTE EPC, between the core network and the radio network. The MME is responsible for handling signals between active UEs and the network within the LTE EPC architecture. It is also responsible for signaling between eNodeBs and the core network. For continuous functionality, MME authenticates UEs by communicating with the HSS, and the mobility function allows the UE to access the network and keeps track of its location and state.

thank you! it was really helpful. i have a question though, do you know how many MMEs are there in a PLMN? i am talking in a practical point of of view, how existing operators define their architectures. thanks in advance !
