Method and residential control node (206) of enabling encrypted residential communication of user data between a first wireless communication device (202) and a second wireless communication device (204). The method comprises receiving (3:3) a radio bearer mapping from a communication network node (220, 700), establishing (3:4) a connection with the first wireless communication device (202), in accordance with the radio bearer mapping, and establishing (3:5) a connection with the second wireless communication device (204), in accordance with the radio bearer mapping. Furthermore, the method comprises obtaining (3:7) a first key which is based on a key of the first wireless communication device (202), from the communication network node (220, 700), and obtaining (3:7) a second key which is based on a key of the second wireless communication device (204). Thereby, the residential control node (206, 600) is enabled to decrypt (3:10) user data received (3:9) from the first wireless communication device (202) by the first key, and encrypting (3:10) the user data by the second key, before sending (3:11) the user data to the second wireless communication device (204).;By arranging residential control nodes locally, wireless communication devices may be enabled to communicate securely with each other without passing the user data via the core network, which may reduce load on communication links of transport networks. Furthermore, end users of the wireless communication devices may perceive increased communication rates and less delay when communicating user data. |
