Abstract: A first network node of a first frequency layer, acquires (201) information on services that are offered by a second network node at a second, different frequency layer. The second network node is within the coverage area of the first network node. The first network node broadcasts (202) a service advertisement message to at least one terminal device (UE) for advertising the services offered by the second network node at the second frequency layer.

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.

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: A shortage of at least one resource is determined in a first radio network control entity that has joined a pool of radio network control resources. The first radio network control entity signals to at least one second radio network control entity of the pool a request for at least one resource. The at least one second radio network control entity receives the request for at least one resource and offers for the first radio network control entity.

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: There are provided measures for improvements in dual connectivity for different access networks. Such measures exemplarily comprise providing control in a control plane for a terminal (UE) for access to a first access network (5G), wherein a coverage of the first access network (5G) at least partly overlaps a coverage of a second access network (4G), the terminal is capable of having access to the first access network (5G) and to the second access network (4G) in parallel, and access for the terminal to a respective access network (4G, 5G) is routed in a user plane via a respective distinct access network entity (eNB, SGAP) and to a respective (compatible) gateway (S-GW, uGW).
