Hello everyone,
We are currently working with a CPE that supports both LTE FDD and TDD bands, as well as NSA Dual Connectivity (DC).
To differentiate user profiles, we have configured two SPIDs:
SPID 10: for NSA DC users
SPID 15: for LTE TDD-only users
The challenge we’re facing is that CPEs with SPID 15 sometimes attach to the LTE FDD layer, and once attached, they don’t switch to TDD, which is not the desired behavior.
We considered using inter-frequency relations between FDD and TDD, but this approach allows mobile users to access TDD bands — which would violate our client strategy.
Our objective is to restrict SPID 15 users to connect only to LTE TDD while keeping mobile users unaffected.
Has anyone faced a similar scenario or found a clean way to enforce such SPID-based access control without modifying inter-frequency relations?
Any insight on parameter configurations or alternative solutions would be highly appreciated.
Thank you in advance.
