Abstract
Apparatuses, methods, and systems are provided for virtualizing a reprogrammable universal integrated circuit chip (UICC) in a connected device's operating system. In one embodiment, an integrated cellular modem in the connected device is configured to use a simple protocol to communicate with the reprogrammable UICC. The protocol may be implemented in a way that allows cellular modem vendors to easily support such functionality and allow original equipment manufacturers to upgrade connected devices already deployed in the field.
Claims24
A mobile station comprising:
- an application processor physically connected to a baseband processor, wherein the physical connection facilitates secure transmission of commands to the application processor from a cellular modem application hosted by the baseband processor;
- and
- one or more memories storing computer-executable instructions that, when executed, configure a mobile application running on the application processor to, in response to receipt of one or more commands from the baseband processor, communicate via a radio interface layer of the application processor with a virtual reprogrammable universal integrated circuit chip (eUICC) that is not physically or electrically connected to the baseband processor,
- wherein the computer-executable instructions configure the application processor to communicate with the virtual eUICC by causing the radio interface layer of the application processor to
- transmit the one or more commands to the virtual eUICC,
- receive, from the virtual eUICC, one or more responses to the one or more commands, and
- forward the one or more responses to the baseband processor.
4 more elements
A method comprising:
- providing, in the mobile station, an application processor physically connected to a baseband processor, wherein the physical connection facilitates secure transmission of commands to the application processor from a cellular modem application hosted by the baseband processor;
- and
- in response to receipt of one or more commands from the baseband processor, communicating, by a mobile application running on the application processor and via a radio interface layer of the application processor, with a virtual reprogrammable universal integrated circuit chip (eUICC) that is not physically or electrically connected to the baseband processor,
- wherein communicating with the virtual eUICC includes causing the radio interface layer of the application processor to
- transmit the one or more commands to the virtual eUICC,
- receive, from the virtual eUICC, one or more responses to the one or more commands, and
- forward the one or more responses to the baseband processor.
4 more elements
A mobile station comprising:
- an application processor physically connected to a baseband processor, wherein the physical connection facilitates secure transmission of commands to the application processor from a cellular modem application hosted by the baseband processor;
- and
- means for communicating, by a mobile application running on the application processor and in response to receipt of one or more commands from the baseband processor, with a virtual reprogrammable universal integrated circuit chip (eUICC) that is not physically or electrically connected to the baseband processor,
- wherein the means for communicating with the virtual eUICC includes means for
- transmitting the one or more commands to the virtual eUICC,
- receiving, from the virtual eUICC, one or more responses to the one or more commands, and
- forwarding the one or more responses to the baseband processor.
