Hi @aligungr

Can you please share what features are you planning with UERANSIM in next releases.

Just wanted to know, what else can we get in coming releases.

Thanks @aligungr for taking out time and helping us with this.

Do we have any architecture diagram or sort like that to understand internal working of UERANSIM. e.g. how does it interact with core and protocol used behind YAML file configuration.

@Swapnil-R

I'm currently working on a publication about design and implementation of UERANSIM, and will release after complation.

Thanks

[Swapnil-R]

Thanks @aligungr, the publication would be very helpful.

Meanwhile, can you please suggest where can I check UERANSIM logs to debug more and understand it better.

Hello @aligungr, really appreciate your work on UERANSIM.

I'm curious, if you could approximately tell when Handover feature will be supported in the UERANSIM (few days, weeks, months)?

Thanks in advance.
