Claim 11:
12. A method for enabling communication between a first radio communication device and a network, wherein the first radio communication device is configured to communicate with the network according to a radio protocol stack, the method being performed by a second radio communication device, the method comprising:
negotiating how the radio protocol stack is to be split between the first radio communication device and the second radio communication device, wherein the radio protocol stack being downloaded from the network, the radio protocol stack comprises a user plane protocol and a control plane protocol, the user plane protocol and the control plane protocol are split between the first radio communication device and the second radio communication device;
obtaining at least one key, as derived from credentials of the first radio communication device during authentication of the first radio communication device with the network;
obtaining, as payload and from the first radio communication device, signalling in accordance with an upper part of the radio protocol stack, wherein the upper part of the radio protocol stack corresponds to the user plane protocol; and
forwarding the signalling to the network by executing the remaining part of the radio protocol stack, wherein the at least one key is for use by the second radio communication device when executing the remaining part of the radio protocol stack.
