Abstract: A method and an apparatus for updating an operating, comprising: receiving, by an eUICC, a restart instruction sent by an LPA of a terminal device and used to instruct the eUICC to perform a restart operation; sending, to a modem of the terminal device, a first initialization request used to request the modem to control restart of the eUICC; after being restarted, receiving, by the eUICC, a plurality of OS element data packets that are sequentially sent by the LPA; after receiving a part of OS element data packets in the plurality of OS element data packets, parsing, by the eUICC, the OS element data packets received by the eUICC, and installing a first operating system based on a parsing result; and deleting, by the eUICC, the first OS element data packet.

Abstract: An embedded universal integrated circuit cart (eUICC) profile management method and apparatus to update an operating system of an eUICC include setting, by a local profile assistant (LPA), an operating system update flag, and obtaining and storing first metadata of a first profile. A profile server generates a second profile based on the operating system update flag, and generates second metadata of the second profile. The LPA configures the second metadata based on the first metadata, and activates the second profile based on the second metadata.
