Claim of US Patent No. 10,512,037

12. A wireless communication system configured to control base station selection, wherein the wireless communication system is configured to serve user equipment devices (UEs) including (i) UEs of a first type that support engaging in standalone service on a first radio access technology (RAT) and dual-connectivity service on the first RAT and a second RAT, and (ii) UEs of a second type that support engaging in the standalone service on the first RAT but that do not support engaging in the dual-connectivity service on the first RAT and the second RAT, the system comprising:a plurality of base stations that each support providing the standalone service on a first RAT, wherein the plurality of base stations includes (i) a first base station that additionally supports providing the dual-connectivity service on the first RAT and a second RAT and (ii) a second base station that does not additionally support providing the dual-connectivity service on the first RAT and the second RAT,
wherein the wireless communication system is configured to transmit to a UE prioritization data for use by the UE to select, from at least the first and second base stations, a base station to be a serving base station of the UE, wherein the prioritization data includes (i) first prioritization data that specifies that the first base station prioritizes serving UEs of the first type over serving UEs of the second type and (ii) second prioritization data that specifies that the second base station prioritizes serving UEs of the second type over UEs of the first type,
whereby transmission of the prioritization data facilitates UE selection, from at least the first and second base stations, the base station to be the serving base station of the UE.
