Abstract:
Methods and apparatus for providing a handover of fewer than all bearers associated with a user equipment are disclosed. An example method includes establishing a connection for fewer than all bearers associated with the user equipment, via a selective handover procedure, and receiving, from a source base station or a user equipment, a handover completion message for the fewer than all bearers associated with the user equipment. The example method further includes sending, to a core network node, a request to switch a path for the fewer than all bearers, the request comprising an information element providing an indication of whether or not a control interface connection between the source base station and the core network node should continue to be maintained, and thus not switched to the target base station. In some embodiments, but not all, an acknowledgement message is subsequently received, in response to the request.
