Cell reselection priority assignment based on performance triggers

A method comprising:

• identifying one or more performance degradation triggers of one or more layers of one or more radio cells in a cellular communication network;
• adjusting a cell-reselection priority of each one of the one or more layers identified with the one or more performance degradation triggers,
• wherein the adjusting is based on a default cell-reselection priority of the one or more layers and a relative severity of the one or more performance degradation triggers;
• and
• transmitting, through one or more system information messages, the adjusted cell-reselection priority to one or more user equipment (UE) in the cellular communication network.

A user equipment (UE) in a cellular communication network comprising:

• at least one hardware processor;
• and
• at least one non-transitory memory, coupled to the at least one hardware processor and storing instructions, which, when executed by the at least one hardware processor, cause the UE to:
• receive a default cell-reselection priority transmitted in system information messages broadcast in one or more system information blocks (SIBs),
• wherein the cell-reselection priority assigns a priority indicator value to one or more layers that the UE is compatible with;
• after receiving the default cell-reselection priority, receive an updated cell-reselection priority,
• wherein the updated cell-reselection priority assigns a lower priority indicator value than a default priority indicator value to a layer of the one or more layers when the layer is undergoing a performance degradation;
• and
• perform a cell reselection in IDLE mode based on the updated cell-reselection priority thereby causing the UE to deprioritize selection of the layer that is undergoing the performance degradation.
