You can see the discussion https://www.researchgate.net/post/How_exactly_is_the_5G_handover_simulated_in_NetSim, and in that there is one response describing the flow of all control packets involved in the HO. All these times need to be summed up to get the exact handover duration.

To this an additional handover interruption time can also be added for RF/baseband retuning, derive target eNB specific keys, configure security algorithm etc.

Dear Mohammad Alquraan ,

Adding to Ananya Hegde ,It is required to reduce the interruption of the handover to very small milliseconds.

Ideally zero time. To see the target values for the 5G please refer to the link:https://www.ericsson.com/en/blog/2020/4/reducing-mobility-interruption-time-5g-networks

hi.,

Handover Latency is one of the measure of system performance. As per 3GPP 36.881 the handover latency can be measured by the time UE received handover command (RRC Connection Reconfiguration Incl. In other words we can say the handover latency is the time taken during during handover execution step.
