Operating system establishing method and apparatus

A terminal, comprising:

• an input device, configured to acquire a data selection instruction input by a user, the data selection instruction comprising an identification (ID) of the user and an ID of a profile providing server that is selected by the user, the profile providing server configured to provide a service;
• and
• a processor, configured to:
• start a just enough operating system, and enable a basic application service, wherein the just enough operating system comprises a basic application service module, an operating system core library module, and an instruction translation module, wherein the operating system core library module comprises file storage, execution of supporting the basic application service, Internet access, and input/output, wherein the basic application service comprises a call application, an SMS message application, a browser application, and an input method application;
• determine the profile providing server according to the ID of the profile providing server in the data selection instruction;
• access, by addressing, the profile providing server according to the ID of the user;
• acquire operating system information from the profile providing server, the operating system information comprising information about an operating system providing server;
• access the operating system providing server according to the operating system information;
• and
• acquire an operating system copy, and deploy the operating system copy in an operating system container to establish an operating system, wherein the operating system container is configured to run the operating system copy.

A profile providing server, comprising:

• a receiver, configured to receive a data request message sent by a terminal;
• and
• a transmitter, configured to send, to the terminal, information about a user according to the data request message, the information enabling the terminal to establish an operating system according to the information about the user,
• wherein the profile providing server is selected by the terminal after the terminal acquires a data selection instruction input by the user and before the receiver receives the data request message, wherein the data selection instruction comprises an identification (ID) of the user and an ID of the profile providing server,
• wherein the receiver is further configured to receive an operating system information request message sent by the terminal, the operating system information request message comprising the ID of the user;
• and
• the transmitter is further configured to send, to the terminal, operating system information according to the operating system information request message, the operating system information comprising information about an operating system providing server that is accessible by the terminal to acquire an operating system copy.
