name: MME-UE
full_form: MME serving the UE
context: If end to end protection between the RN and the core network is needed, then the same solution as for backhaul protection should be considered. Integrity protection and confidentiality protection for the S1 control plane traffic shall be mandatory. The S1 control plane traffic between RN and MME-UE shall be integrity protected between the DeNB and the MME-UE with the same strength as in the current EPS architecture. Only hop by hop protection between RN and MME-UE shall be considered as the DeNB acts as an S1-proxy in the solution selected by RAN. The S1 control plane traffic between DeNB and MME-RN shall be integrity protected with the same strength as in the current EPS architecture. NOTE: If NULL encryption algorithm is used, it is essentially the same as providing no confidentiality protection to the S1 control plane traffic. Editorâs note: The need for confidentiality and replay protection of the S1 control plane traffic between DeNB and MME-RN are FFS. Integrity protection for
description: The Mobility Management Entity (MME) is a network function in the Evolved Packet Core (EPC) that manages mobility, authentication, and session management for user equipment (UE). In this context, MME-UE refers to the MME serving the UE, highlighting its role in handling S1 control plane traffic between the Radio Network (RN) and the core network.
explanation: The classification of MME-UE as a Network Function is justified by its involvement in managing UE access and mobility within the network, as well as its participation in securing S1 control plane traffic between RN and the core network.
