Abstract
Integrity protection is activated for user plane data transferred between a network node and a terminal device of the cellular communications network. The activation can be initiated by the terminal device sending a request message to a second network node. Thus, a UE, such as a Cellular IoT UE, and a network node such as a SGSN are able to use LLC layer integrity protection for both control plane and user plane data.
