Description

Technical Field

[0001] The present application relates to the field of cloud mobile phone technology, and in particular to a method for making calls based on a cloud mobile phone, a cloud mobile phone login method and device. Background Art

[0002] As the name implies, a cloud phone is a virtual phone running in the cloud. All operating systems, mobile applications, data storage and computing functions are processed in the cloud and can be controlled through a physical phone, turning one phone into multiple phones. Because it is a virtualization technology, there is no physical hardware or SIM card on the cloud phone, so the cloud phone cannot make calls through the communication network.

[0003] In the related technology, the following two solutions are adopted to enable cloud phones to have the ability to make calls: the first solution is to bind the virtual account in the cloud phone with the main number of the real phone. When the user initiates a call through the cloud phone, the main number is used to send a call request to the virtual number server. The virtual number server converts the main number into a virtual account and calls the called number; the second solution is that the cloud phone obtains the phone call request sent by the user using the real phone, and transmits the phone call request to the client of the real phone. The client obtains the phone call request through the end-side SDK, and calls the current mobile phone system's phone call function according to the phone call request to make a call. In other words, the current cloud phone-based phone call solutions all need to call the phone call function of the real phone. Summary of the invention
