Embodiment 1

[0036] This embodiment provides a call method based on a cloud SIM server, which is applied to a terminal device, and the terminal device has a built-in SIM card. Such as figure 1 As shown, the calling method based on the cloud SIM server comprises the following steps:

[0037] S1. Mount the SIM card to the Maochi device;

[0038] S2. When an external phone calls in, the operator base station sends the call-in request to the Maochi device, and the Maochi device forwards the call-in request to the cloud SIM server, and the cloud SIM server obtains the called phone number from the call-in request and sends it to To the VOIP server, the VOIP server sends the incoming call request to the corresponding terminal device;

[0039] S3. After the terminal device receives the incoming call request, the user chooses to answer and the call connection is successful, and the voice call data is sent to the Maochi device through the VOIP server, and the Maochi device establishes a connection...

Embodiment 2

[0063] This embodiment provides a call system based on a cloud SIM server, such as figure 2 As shown, the system includes a cloud SIM server, a terminal device, a modem pool device, an operator's base station and a VOIP server.

[0064] Among them, the terminal device has a built-in SIM card, and the SIM card is mounted to the Maochi device.

[0065] When an external call comes in, the operator base station sends the call request to the Maochi device, and the Maochi device forwards the call request to the cloud SIM server, and the cloud SIM server obtains the called phone number from the call request and sends it to VOIP The server, the VOIP server sends the incoming call request to the corresponding terminal device;

[0066] When the user of the terminal device chooses to answer the call, the call connection is successful, and the voice call data is sent to the Maochi device through the VOIP server, and the Maochi device establishes a connection with the external phone thro...

Abstract

The invention discloses a call method and system based on a cloud SIM server, and relates to the field of SIM cards. The method includes: mounting the SIM card to the Maochi device; when an external phone calls in, the operator's base station sends the call-in request to the Maochi device, and the Maochi device forwards the call-in request to the cloud SIM server, and the cloud SIM server The called phone number is obtained from the call-in request and sent to the VOIP server, and the VOIP server sends the call-in request to the corresponding terminal device; the user chooses to answer, and the voice call data is sent to the Maochi device through the VOIP server, and the Maochi device passes the operation The commercial base station establishes a connection with the external phone for talking. The present invention mounts the SIM card of the user terminal equipment to the modem pool device, and when an external phone calls in, the call-in request is sent to the user through the operator's base station, the modem pool device, the cloud SIM server, and the VOIP server in order to notify the user Answer, automatically suspend the SIM card when the user does not use the SIM card service, to avoid unnecessary roaming charges.

Description

technical field [0001] The invention relates to the technical field of SIM cards, in particular to a call method and system based on a cloud SIM server. Background technique [0002] With the gradual development of internationalization and the imperfection of existing technologies, SIM card users will generate higher fees when using SIM card services abroad, and users have to carry their own SIM cards to go out in order to facilitate contact. Therefore, how to solve the problem of higher telephone charges when the mobile phone roams in different places has become a difficult problem to be solved by those skilled in the art. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a call method and system based on a cloud SIM server, which can save roaming charges. [0004] The technical scheme adopted in the present inve...
