Samsung patents method to manage multiple eSIM profiles on devices
Samsung has filed a patent application for a method to install and manage multiple eSIM profiles on a device. The system uses a local component to communicate with the embedded SIM chip, allowing the device to enable specific profiles and refresh the connection port when necessary.
In the filing’s own words
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure relates to a method and apparatus for connecting communication by downloading and installing one or more communication services in a terminal in a wireless communication system. In addition, the disclosure relates to a method and apparatus for remotely downloading and installing a profile in a terminal, and managing a plurality of installed profiles.
What exactly they claim (claim 1)
1. A method performed by a device in a wireless communication system, the method comprising: identifying, by a local profile assistant (LPA) in the device, information associated with a target profile to be enabled; sending, by the LPA to an embedded universal integrated circuit card (eUICC) in the device, a first message to enable the target profile, the first message including a refresh flag indicating whether a refresh operation of a target port corresponding to the target profile is required and a port number of the target port; in case that the refresh flag indicates that the refresh operation of the target port is required, obtaining, by a baseband component in the device from the eUICC, a second message to trigger the refresh operation of the target port; and based on obtaining the second message, sending, by the baseband component to the eUICC, a terminal response message, or resetting, by the baseband component, the target port.
