Abstract: In an wireless communication system, base stations will be set to prioritize serving one type of user equipment device (UE) over another type of UE, and each base station's respective prioritization will be conveyed to UEs to facilitate base station selection. That way, when a UE faces a choice of whether to connect with one base station or another, the UE could determine which base station gives higher priority to the UE's type and could connect with that base station, even if the UE detects stronger coverage of the other base station. And if the UE finds itself in coverage of a base station that gives lower priority to the UE's type than to another UE type, the UE could still connect with that base station unless the UE finds another base station that gives higher priority to the UE's type.

Abstract: A method for controlling handover of a user equipment device (UE) between (i) a first cell site that provides dual-connectivity service on a first radio access technology (RAT) and a second RAT and (ii) a second cell site that provides standalone first-RAT service, wherein the handover includes transitioning the UE from source first-RAT service to target first-RAT service. The method includes setting a handover threshold to use as a basis to evaluate whether target first-RAT coverage detected by the UE is sufficiently stronger than source first-RAT coverage detected by the UE, where setting the handover threshold includes setting the handover threshold to a value selected based on whether the UE has detected that second-RAT coverage of the first cell site meets a defined threshold measurement threshold. Further, the method includes applying the set handover threshold as a basis to control whether to invoke the handover of the UE.
