Abstract: The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding radio access network (RAN) controlled access of user equipment (UE) to wireless communication networks. The method includes receiving, at a base station or controller of a cellular communication network, a request to offload traffic to a wireless communication network from an access point of the wireless communication network regarding user equipment served by the base station or controller, determining, at the base station or controller, whether to permit the user equipment to offload traffic to the wireless communication network, and transmitting a message indicating whether it is permitted to offload traffic to the access point of the wireless communication network.

Abstract: Disclosed is a method comprising transmitting a beam switch request from a first distributed unit to a second distributed unit. The first distributed unit then receives a beam switch acknowledgment from the second distributed unit. The first distributed unit transmits a beam switch notification to a central unit, wherein the first distributed unit and the second distributed unit are at least partly controlled by the central unit. The first distributed unit further transmits a beam switch command to a terminal device.

Abstract: There are provided measures for improvements in small cell mobility with dual/multi connectivity. Such measures exemplarily comprise terminating at least one control plane signaling connection from said terminal for said at least first network access entity and second network access entity, maintaining a terminal related access stratum context commonly for radio accesses of said terminal to said at least first network access entity and second network access entity, and initiating switching of said radio access of said terminal from said first network access entity to said second network access entity for user plane data transfer with said control plane signaling connection for said second network access entity being applied unchanged, thereby providing, in a control plane for a terminal, connection management for at least a first network access entity and a second network access entity, wherein said at least first network access entity and second network access entity providing radio access for user plane data transfer for said terminal, wherein said terminal being capable of having radio access to said at least first network access entity and second network access entity for user plane data transfer.

Abstract: A method and apparatus can be configured to notify that the apparatus has changed a network node upon which the apparatus is camped on. The apparatus changes from camping on a first network node to camping on a second network node. The apparatus is in idle mode while camping on the first and the second network node. The first network node and the second network node both belong to a first network. The notifying is performed when the apparatus maintains a session to a third network node of a second network. The notifying is not performed when the apparatus is not maintaining a session to the third network node of the second network.
