Abstract
The method includes: a first electronic device obtains a video call task request sent by a third electronic device; the first electronic device detects that the first electronic device is currently configured with no camera; the first electronic device establishes a voice call task with the third electronic device; the first electronic device sends a probe frame to an external camera; a communication module in the external camera is powered on in a process in which the external camera approaches the first electronic device; the external camera obtains the probe frame; the external camera sends a response frame to the first electronic device; and the first electronic device switches the voice call task to a video call task.
Claims20
A video call method, wherein the method is applied to a system comprising a first electronic device and an external camera, and the method comprises:
- obtaining, by the first electronic device, a video call task request sent by a third electronic device;
- detecting, by the first electronic device, that the first electronic device is currently configured with no camera;
- establishing, by the first electronic device, a voice call task with the third electronic device;
- sending, by the first electronic device, a probe frame to the external camera, wherein the external camera is in a state in which no connection is established to the first electronic device;
- powering on a communication module in the external camera during which the external camera approaches the first electronic device;
- obtaining, by the external camera, the probe frame;
- sending, by the external camera, a response frame to the first electronic device in reply to the probe frame;
- and
- switching, by the first electronic device, the voice call task to a video call task, wherein the video call task is between the first electronic device and the third electronic device.
A video call method, wherein the method is executed by an external camera, the external camera is in a state in which no connection is established to a first electronic device, and the method comprises:
- powering on a communication module in the external camera during which the external camera approaches the first electronic device;
- obtaining, by the external camera, a probe frame;
- sending, by the external camera, a response frame to the first electronic device in reply to the probe frame;
- establishing, by the external camera, an electrical connection to the first electronic device after the external camera is plugged into an interface of the first electronic device;
- sending, by the external camera, a video stream to the first electronic device, wherein a parameter of the video stream is a first video call parameter of the external camera;
- receiving, by the communication module in the external camera, a first request message sent by the first electronic device;
- and
- sending, by the communication module in the external camera, a first response message to the first electronic device, wherein the first response message carries the parameter of the external camera.
An electronic device, comprising:
- one or more processors, a memory, and one or more programs, wherein the one or more programs are stored in the memory, and upon execution by the processor, the one or more programs cause the electronic device to perform a connection establishment method including:
- powering on a communication module in an external camera during which the external camera approaches a first electronic device;
- obtaining, by the external camera, a probe frame;
- sending, by the external camera, a response frame to the first electronic device in reply to the probe frame;
- establishing, by the external camera, an electrical connection to the first electronic device after the external camera is plugged into an interface of the first electronic device;
- sending, by the external camera, a video stream to the first electronic device, wherein a parameter of the video stream is a first video call parameter of the external camera;
- receiving, by the communication module in the external camera, a first request message sent by the first electronic device;
- and
- sending, by the communication module in the external camera, a first response message to the first electronic device, wherein the first response message carries the parameter of the external camera.
