Optimizing UMTS to LTE PS Traffic Migration (Huawei)

Hello experts, what parameters do you recommend adjusting to facilitate the migration of UMTS PS traffic to LTE for Huawei networks?

Are you decommissioning the UMTS service, or are you simply adding LTE alongside it?

Simply integrating LTE alongside the existing UMTS service.

The best approach is to attract users from idle mode by setting higher reselection priorities for LTE.

For example, assign UMTS a reselection priority of 3-4 and LTE a priority of 5-6.

Oh, thank you! I’ll implement it.

What about the parameters for connected mode?

In connected mode, ensure the UE remains in LTE until -120 dBm.

Only when the signal drops below this threshold should an inter-RAT handover or redirection be triggered.

Reduce ThreshXhigh at the LTE layer to enable faster UE movement, and increase RSCP ThreshXlow at the 3G end.
