'XCAL Drive Test Tool by Accuver' can be used to observe the live signalling messages from the UE and enodeB end. So, when you switch to a new cell, if the handover takes place, the signalling messages will be available to observe the handover analysis. However, this software requires license and is not available for free. Hope it helps!
Have you looked at NetSim (https://www.tetcos.com/5g.html)?
There are several MAC/PHY parameters you could vary and the ones specific to handover modeling are: (i) Handover margin or Offset (ii) Time to trigger, and (iii) Handover interruption time.

There are several software tools available for handover analysis of 4G and 5G mobile systems. Here are some popular options:
Keysight XCAL: XCAL is a comprehensive tool for cellular network testing and analysis, including handover analysis. It supports 4G and 5G networks and can analyze handover performance across different network types, including macro, small cell, and DAS networks.
Anritsu MasterClaw: MasterClaw is an advanced network testing and analysis tool that supports 4G and 5G networks. It can analyze handover performance in real-time and provide detailed reports on handover success rate, latency, and other key performance indicators.
Rohde & Schwarz ROMES: ROMES is a network optimization and testing tool that supports 4G and 5G networks. It includes a handover analysis module that can provide detailed reports on handover performance, including handover success rate, latency, and handover cause.
Accuver XCAL-M: XCAL-M is a mobile network testing and analysis tool that supports 4G and 5G networks. It includes a handover analysis module that can provide detailed reports on handover performance, including handover success rate, latency, and handover cause.
PCTEL SeeHawk: SeeHawk is a network testing and analysis tool that supports 4G and 5G networks. It includes a handover analysis module that can provide detailed reports on handover performance, including handover success rate, latency, and handover cause.
These software tools can help network operators and engineers to analyze the handover performance of 4G and 5G networks and identify areas for improvement. It is important to choose a tool that is compatible with the specific network equipment and protocols being used, and to ensure that the tool provides the necessary level of detail and accuracy for the specific analysis being performed.
