Handover control

An apparatus for handover control in a mobile communication system, the apparatus comprising at least one processor and at least one memory including a computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to:

• receive handover information reports from user equipment,
• generate a qualitative handover information report for input to a handover optimizer function, the generating comprising mapping failure cause information in the received handover information reports to sets of qualified failure types based on the extend of the failure causes, and
• send the qualitative handover information report comprising information of the generated sets of qualified failure types to the handover optimizer function.

An apparatus for a handover optimizer function in a mobile communication system, the apparatus comprising at least one processor and at least one memory including a computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to:

• receive a qualitative handover information report comprising aggregated information of sets of qualified failure types mapped from handover information reports from user equipment based on the extend of failure causes, and
• control at least one handover parameter based on the aggregated information of the sets of qualified failure types.

A method for handover control in a mobile communication system, the method comprising:

• receiving handover information reports from user equipment,
• generating a qualitative handover information report for input to a handover optimizer function, the generating comprising mapping failure cause information in the received handover information reports to sets of qualified failure types based on the extend of the failure causes, and
• sending the generated qualitative handover information report comprising information of the sets of qualified failure types to the handover optimizer function.
