name: MME
full_form: Mobility Management Entity
context: the product implements the minimum set of functions listed in clause 4.2 (a short list of MME functions from TS 23.401 Release 8 [4]). - The MME NPC is the set of all MME NPs. Need for an MME network product model: This minimum set of functions listed in clause 4.2 is exclusively meant as a membership criterion for the MME NPC. It is not meant to restrict the functionality of an MME NP, or the scope of the MME SCAS, in any way. On the contrary, it is clear that MME NPs will contain many more functions than those from the minimum set listed in clause 4.2, and the MME SCAS will contain requirements relating to functions not contained in this minimum set. Some of these functions, beyond the minimum set, can be found from various 3GPP specifications, but by far not all these functions. This implies that there is a need to describe the functions that cannot be found from 3GPP specifications in some other way before the MME SCAS can be written so that the MME SCAS can make reference to this
description: The Mobility Management Entity (MME) is responsible for managing mobility-related tasks, such as user authentication and session management, in the Evolved Packet Core (EPC) of LTE networks.
explanation: The text explicitly states that MME is a network function within the EPC, highlighting its role in managing mobility aspects.
