Abstract: A method and apparatus may include determining, by a network node, that a slave radio-resource-control function is to be initiated. The slave radio-resource-control function may be performed by an access point. The method may also include transmitting a message to the access point. The message includes at least one of a request to initiate the slave radio-resource-control function and a confirmation that the slave radio-resource-control function can be initiated.

Abstract: A method and apparatus may include transmitting a measurement split request to a network node. The measurement split request designates a first measurement layer and a second measurement layer. The first measurement layer corresponds to a measurement configuration for the apparatus. The second measurement layer corresponds to a measurement configuration for the network node. The method may also include receiving an acknowledgement that the measurement split request is accepted by the network node. The method may also include transmitting the measurement configuration for the apparatus and the measurement configuration for the network node to a user equipment.

Abstract: Methods and apparatuses for controlling communication with a communication device connected to a plurality of access points are described. Predefined inactivity in communications between a first access point and the communication device may be determined at the first access point. An indication of predefined inactivity in communications between the communication device and a second access point may be provided by the second access point. Connectivity state of the communication device is only changed when said predefined inactivity in communications between the first access point and the communication device has been determined and said indication has been provided.
