US 11,638,189 B2 · System and method for minimizing transitions between core networks

Abstract

A method, a system, and a non-transitory storage medium are described in which a core network selection service is provided. The core network selection service may minimize end devices transitioning between core networks of a multi-radio access technology (RAT) radio access network (RAN) based on cell selection priority configurations. The cell selection priority configurations may be provisioned on the end device via control messaging, such as system information block messages. The core network selection service may manage the end devices when in idle mode and in a connected mode.

Dependent claims

A method comprising:

generating, by wireless stations of a multi-radio access technology (RAT) radio access network (RAN) that includes a new radio (NR) RAN and a RAN of a Long Term Evolution (LTE) network, a system information block (SIB) message that includes cell reselection priority information, wherein an order of priority configures an end device to camp on only an LTE cell unless the end device moves to a first area of the multi-RAT RAN that provides NR stand-alone (SA) uplink and downlink coverage, and further configures the end device to camp on only an NR SA cell, unless the end device moves to a second area of the multi-RAT RAN that provides only LTE uplink and downlink coverage, and further includes a parameter value relating to a calculation of a cell selection criterion S value that configures and prevents the end device from camping on a first wireless station of the wireless stations;
and
broadcasting, by the wireless stations, the SIB message to the end device.

A system comprising:

wireless stations of a multi-radio access technology (RAT) radio access network (RAN) that includes a new radio (NR) RAN and a RAN of a Long Term Evolution (LTE) network, wherein each wireless station comprises a processor configured to:
generate a system information block (SIB) message that includes cell reselection priority information, wherein an order of priority configures an end device to camp on only an LTE cell unless the end device moves to a first area of the multi-RAT RAN that provides NR stand-alone (SA) uplink and downlink coverage, and further configures the end device to camp on only an NR SA cell, unless the end device moves to a second area of the multi-RAT RAN that provides only LTE uplink and downlink coverage, and further includes a parameter value relating to a calculation of a cell selection criterion S value that configures and prevents the end device from camping on a first wireless station of the wireless stations;
and
broadcast the SIB message to the end device.
