Determination for conditional handover failure

An apparatus comprising:

• at least one processor, and
• at least one memory comprising a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
• upon detecting that a first condition is met, cause a transmission of a measurement report to a wireless network;
• acquire a conditional handover command from the wireless network;
• upon detecting that a second condition, associated with the conditional handover command, is met, start a handover execution timer for triggering execution of a handover from a source cell to a target cell, wherein handover is triggered at an expiry of the handover execution timer;
• detect that a radio link failure condition is met before the execution of the handover is triggered by expiry of the handover execution timer;
• and
• on the basis of the detecting that the radio link failure condition is met, signal, to the wireless network, information indicative of a cause of a conditional handover failure to be either a misconfiguration of the first condition or a misconfiguration of the second condition;
• wherein the information indicative of the cause of the conditional handover failure comprises timing information being indicative of a time period between the starting the handover execution timer and the acquiring the conditional handover command.

A non-transitory computer program product embodied on a distribution medium readable by a computer and comprising program instructions which, when executed by an apparatus, cause the apparatus at least to:

• upon detecting that a first condition is met, cause a transmission of a measurement report to a wireless network;
• acquire a conditional handover command from the wireless network;
• upon detecting that a second condition, associated with the conditional handover command, is met, start a handover execution timer for triggering execution of a handover from a source cell to a target cell, wherein handover is triggered at an expiry of the handover execution timer;
• detect that a radio link failure condition is met before the execution of the handover is triggered by expiry of the handover execution timer;
• and
• on the basis of the detecting that the radio link failure condition is met, signal, to the wireless network, information indicative of a cause of a conditional handover failure to be either a misconfiguration of the first condition or a misconfiguration of the second condition;
• wherein the information indicative of the cause of the conditional handover failure comprises timing information being indicative of a time period between the starting the handover execution timer and the acquiring the conditional handover command.
