  • Patent number: 11968586
    Abstract: A network node of a wireless communication network provides information to a User Equipment (UE) that allows the UE to adapt it radio measurements with respect to the network, to account for “link changes.” Link changes are service-link and/or feeder-link changes arising from motion by the satellite(s) included in the Radio Access Network (RAN) portion of the network. The UE uses the provided information to adapt its radio measurements in conjunction with the link changes. Among the several advantages of accounting for satellite link changes in the manner contemplated are any one or more of reduced signaling going between the UE and the network, reduced battery consumption at the UE, mitigation of the effects of the link changes on the radio measurements, avoidance of spurious measurements, and an effective “automation” of the timed changeover by the UE to new measurement configurations, coincident with the occurrence of link changes.

  • Patent number: 11943706
    Abstract: A wireless device, UE, in a communication network receives satellite positioning information and a list of a plurality of different types of measurements to perform to find a public land mobile network, PLMN, to select. The UE performs the plurality of different types of measurements on a frequency associated with a found PLMN to generate a plurality of measurement results. The UE determines, based on the plurality of measurements results, whether a high-quality indication should be provided to a non-access stratum, NAS. Responsive to determining that the high-quality indication should be provided, the UE provides the high quality indication and an identification of the found PLMN to the NAS.
