Identifying origin and destination pairs

An apparatus for identifying a missing point in an origin/destination pair, the apparatus comprising:

• a current time determining unit configured to, in response to failure of a current operation for recording an origin/destination pair associated with a user, determine a current time when the current operation is executed;
• a previous time determining unit configured to determine a previous time when a last operation for recording the origin/destination pair was executed;
• and
• a missing point identifying unit configured to identify a missing point causing the failure of the current operation based on a time interval between the current time and the previous time.

A computer program product for identifying an origin/destination pair in a service, the computer program product comprising:

• a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• determining a current time when a current operation is executed in response to a failure of the current operation for recording the origin/destination pair associated with a user;
• determining a previous time when a last operation for recording the origin/destination pair was executed;
• and
• identifying a missing point causing the failure of the current operation based on a time interval between the current time and the previous time.
