name: S1-U
full_form: S1 User Plane Interface
context: The network may include this IE to inform the UE of the support of certain features. If this IE is not included then the UE shall interpret this as a receipt of an information element with all bits of the value part coded as zero, except for the S1-u data transfer (S1-U data) (octet 4, bit 2).
  NOTE: In this exceptional case, the UE deems that the network supports S1-u data transfer.
description: The S1-U interface refers to the user plane aspect of the S1 interface, which connects the eNodeB with the Serving and Packet Data Network Gateway (PDN-GW). It is used for the transfer of user data.
explanation: S1-U is categorized as an Interface because it enables the transfer of user plane data between network components.
