5G SA reselection inter vendor

[oswe]

hello guys,
we have inter vendor scenario Nokia on LTE and /// on 5G SA.
we are trying to reselect to 5G . we heard NRFIM+SIB24 will do it... but we have some strange cases where those MOs are not created and telephone reselects by itself to 5G SA . very strange
has anyone faced this scenario ?

Here are some steps to check

1. Incomplete Inter-Vendor Handoff: It’s possible the handoff process between Nokia LTE and the other vendor’s 5G SA isn’t fully configured. This could lead to the phone initiating reselection itself, bypassing the NRFIM/SIB24 process.
2. Vendor Specific Behavior: Different vendors might have their own proprietary mechanisms for triggering reselection. This could explain why the phone reselects on its own in some cases.
3. Network Misconfiguration: There might be a configuration issue on either the Nokia LTE or the other vendor’s 5G SA network that’s causing the unexpected reselection behavior.

Here’s what you can do:

• Check Vendor Documentation: Refer to the documentation for both Nokia and the other vendor to understand their specific inter-vendor handoff procedures and potential reselection triggers.
• Analyze Network Logs: Look for any error messages or unusual events in the network logs from both Nokia LTE and the 5G SA network around the time of these unexpected reselections.
• Contact Network Support: Reach out to the support teams of both Nokia and the other vendor to report the issue and see if they have any known solutions or workarounds.

Additional Tips:

• See if there are any firmware updates available for the Nokia LTE equipment or the user devices experiencing these reselection issues.
• Investigate if there are any ongoing network maintenance activities that might be impacting the handoff process.

thanks Ranen for taking the time.
We saw the Xcal trave on the mobile station and nothing... there´s no sib24 nor any RRCReconfiguration message. it just goes to 5G as it knew it should go... hehe!
like I said, the lte configuration doesnt have sib24 or 5g frequency in any MO.
we cant ask. Nowadays we have projects where you have 1 vendor that´s not "your" equipment. so there´s no support for it... that is the harsh reality at least here in southAmerica so you cant just "ask" for support to 4g lte vendor...

thanks anyway !

I see you are using Accuver Xcal for testing purposes, let me know what version of Xcal you are using and also what licenses are enabled?

The Accuver's Xcal DT software is by my opinion far more advanced than competition T...s and Ne..o, however, they limit features by license.
