Patent number: 11490263Abstract: In one example, a user equipment (UE) has a non-Third Generation Partnership Project (non-3GPP) radio transceiver for communication in a local private non-3GPP wireless network and a 3GPP radio transceiver for communication in a 3GPP network, where the 3GPP network may be a public 3GPP network or a local private 3GPP network operative in a shared spectrum according to a system for shared spectrum access. Initially, the UE may operate the 3GPP radio transceiver for communication in the public 3GPP network, without performing regular scanning for the local private 3GPP network. In a scan operation using the non-3GPP radio transceiver, the UE may receive from a non-3GPP access point of the local private non-3GPP wireless network one or more messages including one or more information elements. If an information element indicates presence of the local private 3GPP network, the UE may identify and register with the local private 3GPP network.Type: GrantFiled: October 2, 2019Date of Patent: November 1, 2022Assignee: CISCO TECHNOLOGY, INC.Inventors: Rajesh S.
