Method for using cellular communication function, and related apparatus and system

A first electronic device, comprising:

• one or more processors, a memory, a display, a wireless communication module, and a mobile communication module, wherein
• the memory, the display, the wireless communication module, and the mobile communication module are coupled to the one or more processors, the memory is configured to store computer program code, the computer program code comprises computer instructions, and when the one or more processors execute the computer instructions;
• the first electronic device comprise a distributed cellular communication module, and the distributed cellular communication module of the first electronic device is run in a system service or arranged in an application framework layer or a system library of the first electronic device;
• the first electronic device performs a method, the method comprising:
• receiving a cellular communication service request;
• forwarding the received cellular communication service request to a distributed cellular communication module of a second device, wherein the distributed cellular communication module of the second device is run in a system service or arranged in an application framework layer or a system library of the second device;
• receiving response data corresponding to the cellular communication service request and returned by the distributed cellular communication module of the second device, wherein the response data corresponding to the cellular communication service request is obtained by sending the cellular communication service request to a modem Modem of the second device by the distributed cellular communication module of the second device and processing the cellular communication service request by the Modem of the second device;
• and
• sending the response data corresponding to the cellular communication service request to an application corresponding to the cellular communication service request.
