Abstract: A method of carrying out dual connectivity with a secondary access node and an apparatus is provided. A mode of operation of a user equipment is determined in dependence on the presence of bearers mapped to the secondary access node. Operating in a first mode occurs when it is determined that one or more bearers are mapped to a secondary access node. Operation in a second mode occurs when it is determined that no bearers are mapped to the secondary no access node. The second mode comprises limiting a listening time to a downlink channel from the secondary access node with respect to the first mode.

Abstract: Various communication systems may benefit from appropriate restriction on use. For example, certain wireless communication systems may benefit from radio-access-technology-specific access restrictions. A method can include registering a user equipment with a network element. The registering can include identifying user equipment capabilities. The method can also include receiving a response from the network element indicating restriction on use of at least one radio access technology.

Abstract: Methods and apparatuses for controlling dual connectivity in a communication system are disclosed. Information on at least one failure in relation to a cell change of a communication device connected to a master access point and a secondary access point is determined. The determined information is communicated to the secondary access point. The secondary access point uses the information in mobility control.
