Abstract
A method performed by a user equipment, UE, for enabling a user plane integrity protection mode in a radio access network packet data convergence protocol, PDCP, is provided. The method includes providing an indication of a user plane integrity protection, UP IP, mode supported by the UE. The method further includes receiving an activation message from a receiving node that includes an indication to the UE to activate the UP IP mode. The receiving node is a long term evolution eNodeB. Methods performed by a network node and a radio access node are also provided.

A method performed by a user equipment, UE, for enabling a user plane integrity protection mode in a radio access network packet data convergence protocol, PDCP, the method comprising:
- providing an indication of a user plane integrity protection, UP IP, mode supported by the UE;
- and
- receiving an activation message from a receiving node that includes an indication to the UE to activate the UP IP mode, wherein the receiving node is a long term evolution eNodeB;
- and
- sending an attach request to a core node that includes the indication of the UP IP mode supported by the UE.

A method performed by a network node for enabling a user plane integrity protection mode in a radio access network packet data convergence protocol, PDCP, the method comprising the method comprising:
- handling an indication of a user plane integrity protection mode supported by a user equipment, UE;
- receiving an attach request from the UE that includes the indication of the UP IP mode supported by the UE;
- responsive to the attach request, establishing a secure connection between the UE and the radio access network;
- and
- sending a message to a long term evolution e Node B that includes the indication of the UP IP mode.
