Hello SymbilWu… I have done more detailed testing with single HTC UE and E/// BBU and please find below the observations and logs attached… Thank you
2- de-register and then register the UE back (without restarting Core)
a. UE was able to register and establish PDU session the first 2 times of de-register and register
b. 3rd time onward, UE registers successfully but have issues with PDU and seeing the errors below……Please note the below errors were observed at different times after UE de-register and register.
Possible Cause: unmarshaling error
Work Around: If we notice the below error, we can then forcekill and restart the Core
Errors:
