Abstract

The present disclosure relates generally to wireless communication. A method performed by a first core network element includes receiving, from a first wireless device, a first message for a registration request with a first wireless network, wherein: the first wireless device has a dual boot relationship with a second wireless device; the first wireless device and the second wireless device are respectively identified by a first SUPI and a second SUPI; the first message carries at least one of: a first 5G-GUTI of the first wireless device; a SUCI of the first wireless device; a dual boot capability of the first wireless device; a first indication that the first wireless device has the dual boot capability; or a second indication that the first wireless device has the dual boot relationship with the second wireless device; and obtaining at least one subset of first context information for the first wireless device.
