Improvements in dual connectivity for different access networks

A device, comprising:

• a processor configured to provide, in a control plane for a terminal capable of having access to a first access network and to a second access network in parallel, connection management for an access network entity of said second access network, wherein
• a coverage of the first access network at least partly overlaps a coverage of the second access network,
• access for the terminal to a respective access network is routed in a user plane via a respective distinct access network entity and to a respective compatible gateway, and
• control in said control plane for said terminal for access to said first access network and to said second access network is provided by a packet core network entity,
• wherein
• the processor is configured to
• receive, in the control plane, messages related to a connection procedure with said terminal for access to said second access network, and
• forward, in the control plane, said messages related to said connection procedure with said terminal for access to said second access network.

A method, comprising:

• providing control in a control plane for a terminal for access to a first access network, wherein
• a coverage of the first access network at least partly overlaps a coverage of a second access network,
• the terminal is capable of having access to the first access network and to the second access network in parallel, and
• access for the terminal to a respective access network is routed in a user plane via a respective distinct access network entity and to a respective compatible gateway,
• the method further comprising:
• receiving, via an interface from a packet core network entity providing control in said control plane for said terminal for access to said second access network, a message indicative of said terminal to be registered, and
• registering said terminal as being capable of having access to the first access network.
