Abstract: According to an aspect, a network node operating in a first RAN according to a first RAT receives a handover request for a user equipment from a cell in a second RAN operating according to a second RAT. After handover of the user equipment to a cell in the first RAN is completed, the network node configures the user equipment to measure frequencies corresponding to the second RAN. Based on measurements reported by the user equipment for the frequencies, the network node identifies detected cells exceeding a measurement threshold, and sends a handover report towards the second RAN. The handover report includes, for at least one detected cell exceeding the measurement threshold, a physical cell identifier and a frequency identifier for the detected cell. The network node obtains configuration information for the detected cell, from another node, and uses the obtained configuration information for subsequent mobility procedures.

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.

Abstract: Example embodiments presented herein are directed towards a network node (401A, 401B) (e.g., a source or target base station), and corresponding method therein, for managing a user equipment time offset measurement by accounting for a user equipment mobility profile. The management may involve a source network node (401A) delaying or preventing the sending of a user equipment timing offset measurement to a target network node (401B) or sending an indication or a reliability of the user equipment timing offset measurement. The network node (401A, 401B) may further apply a compensation to the user equipment timing offset measurement to account for an expected behavior of the user equipment based on the mobility profile. The network node (401A, 401B) may also adapt an uplink search window based on the user equipment mobility profile.

Abstract: The present invention provides methods and apparatus for determining the closeness of neighbor cells to a user terminal. A user terminal performs measurements and sends its measurements to a closeness determination node. The closeness determination node computes a closeness fingerprint based on measurements received from the user terminal, and stores the closeness fingerprint in a closeness database. When the closeness of a set of neighbor cells to a user terminal is to be determined, the user terminal may perform fingerprint measurements and send the fingerprint measurements to the closeness determination node. The closeness determination node may then select a set of neighbor cells that are closest to the user terminal based on the comparison of the received fingerprint measurements to the closeness fingerprints stored in the closeness database.
