Small cell mobility with dual/multi connectivity

An apparatus comprising:

• at least one processor,
• at least one memory including computer program code, and
• at least one interface configured for communication with at least another apparatus,
• the at least one processor, with the at least one memory and the computer program code, being configured to cause the apparatus to perform
• 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,
• 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 an access stratum context related to the terminal, maintained commonly for radio accesses of said terminal to said at least first network access entity and second network access entity, the access stratum context being a common terminal context for radio access technologies of different types involved in providing multi-connectivity services for the terminal, wherein the access stratum context is responsible for transporting data and managing resources, 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.
