Abstract: A method may include receiving a request for conditional handover from a source node. The method may also include sending a conditional handover request acknowledgment message in response to the request. The method may further include sending a conditional handover cancellation message to a source node. The conditional cancellation message may include a genuine cancellation or a modification-related cancellation. Further, the method may include receiving a response message from the source node in response to the conditional handover cancellation message. In addition, the method may include deciding to keep or release user equipment context based on the response message.
