Method and residential control node for enabling encrypted residential communication of user data between two wireless communication devices. The method comprises receiving a radio bearer mapping from a communication network node, establishing a connection with a first wireless communication device, in accordance with the radio bearer mapping, and establishing a connection with a second wireless communication device, in accordance with the radio bearer mapping. Furthermore, the method comprises obtaining a first key which is based on a key of the first wireless communication device, from the communication network node, and obtaining a second key which is based on a key of the second wireless communication device. Thereby, the residential control node is enabled to decrypt user data received from the first wireless communication device by the first key, and encrypting the user data by the second key, before sending the user data to the second wireless communication device. |
