US 2026/0040202 A1 · PROACTIVELY MOVING USER EQUIPMENT TO PREFERRED CELLGROUPS

Abstract

Proactively moving user equipment (UEs) to preferred cellgroups (preferred cellular generation and frequency layer) improves user experience by triggering steering actions (handovers) for long duration connection devices, such as WiFi access points using cellular connections that remain stationary, even when the UEs do not report conditions that traditionally warrant steering actions. This addresses the scenario in which a stationary use cellular UE, such as a fixed wireless access (FWA) unit that is commonly used as a home WiFi router, is moved from a high bandwidth cell to a lower bandwidth cell as a result of an outage of the high bandwidth cell, but does not report any condition that would trigger a steering action back to the high bandwidth cell when the high bandwidth cell becomes available again. The preferred cellgroups may be UE-specific, and based on factors such as network loading, UE capability, and subscriber data.

Dependent claims

A method of wireless communication, the method comprising:

based on at least determining a first mobility profile for a first user equipment (UE), determining, by a wireless network, a first preferred cellgroup for the first UE, the first preferred cellgroup comprising a preferred radio access technology (RAT) and a first preferred frequency layer;
upon a trigger event:
monitoring whether the first UE is using the first preferred cellgroup;
and
monitoring whether a frequency layer in the first preferred cellgroup is available for a steering action of the first UE, wherein the steering action comprises a handover or a redirection of the first UE to an available frequency layer of the first preferred cellgroup;
and
based on at least the first UE not using the first preferred cellgroup and based on at least the available frequency layer of the first preferred cellgroup becoming available, and without any steering action request by the first UE, instructing the first UE, by the wireless network, to perform the steering action.

4 more elements

A system comprising:

a processor;
and
a computer-readable medium storing instructions that are operative upon execution by the processor to:
based on at least determining a first mobility profile for a first user equipment (UE), determine, by a wireless network, a first preferred cellgroup for the first UE, the first preferred cellgroup comprising a preferred radio access technology (RAT) and a first preferred frequency layer;
upon a trigger event:
monitor whether the first UE is using the first preferred cellgroup;
and
monitor whether a frequency layer in the first preferred cellgroup is available for a steering action of the first UE, wherein the steering action comprises a handover or a redirection of the first UE to an available frequency layer of the first preferred cellgroup;
and
based on at least the first UE not using the first preferred cellgroup and based on at least the available frequency layer of the first preferred cellgroup becoming available, and without any steering action request by the first UE, instruct the first UE, by the wireless network, to perform the steering action.

7 more elements

One or more computer storage devices having computer-executable instructions stored thereon, which, upon execution by a computer, cause the computer to perform operations comprising:

based on at least determining a first mobility profile for a first user equipment (UE), determining, by a wireless network, a first preferred cellgroup for the first UE, the first preferred cellgroup comprising a preferred radio access technology (RAT) and a first preferred frequency layer;
upon a trigger event:
monitoring whether the first UE is using the first preferred cellgroup;
and
monitoring whether a frequency layer in the first preferred cellgroup is available for a steering action of the first UE, wherein the steering action comprises a handover or a redirection of the first UE to an available frequency layer of the first preferred cellgroup;
and
based on at least the first UE not using the first preferred cellgroup and based on at least the available frequency layer of the first preferred cellgroup becoming available, and without any steering action request by the first UE, instructing the first UE, by the wireless network, to perform the steering action.
