Abstract: A method and apparatus may include receiving, by a user equipment from a first access point which supports a first radio access technology, a radio-resource-control (RRC) reconfiguration message including an RRC configuration information of a second access point, after an initiation of a slave RRC at the second access point has been determined. The second access point supports a second radio access technology, and performing, by the user equipment, a random access procedure with the second access point based on the RRC reconfiguration message. The user equipment is configured to have an RRC connection with the first access point and the first access point is a master node.
