Selection/Reselection Priority Problem (GSM-->LTE)

[Muhammad Imran Rafique]

Hi Experts,

System : E// Equipment,

GSM : G10B
WCDMA : W11B
LTE : L12B

We just have activated selection priority (idle) mode and parameters are set to get priority in following order.


FDD - LTE
TDD - LTE
UTRAN
GSM



Everything is going fine, but following abnormality is observed and still under investigation.

GSM --> TDD is not happening directly, its only possible via UTRAN. So first GSM-->UTRAN-->TDD(LTE), please let us know what could be the reason.

Please note, SYS INFO is transmitting correct parameters but reselection direction on LTE-TDD is not happening.

LTE-FDD is fine, no issue found.
