name: APN
full_form: Access Point Name
context: The default APN allows access to only the OCSP server. NOTE 1: A Default APN is defined as the APN which is marked as default in the subscription data and used during the Attach procedure and the UE requested PDN connectivity procedure when no APN is provided by the UE, cf. 23.401 [16], clause 3. A2. The MME-RN runs EPS AKA with the RN and the USIM-RN and establishes NAS security. The RN shall use only keys in an RN attach procedure that were received from the USIM-RN over the Secure Channel. A3. The MME-RN checks from the RN-specific subscription data received from the HSS that the USIM-RN is dedicated to the use in RN attach procedures. If the RN requested access to an APN other than the default APN the MME shall reject the request. The MME-RN communicates the fact that the attachment is for relay nodes to the DeNB in an extended S1 INITIAL CONTEXT SETUP message. A4. Upon receipt of the extended S1 INITIAL CONTEXT SETUP message the DeNB sets up AS security over Un as defined for
description: An Access Point Name (APN) is a gateway between a mobile network and an external packet data network, such as the internet. It represents a logical connection point to the network, enabling communication between the UE (User Equipment) and the PDN (Packet Data Network).
explanation: The context describes APN as a point of connection between networks, facilitating data transfer. This function directly relates to the core concept of a network.
