Detailed Description
The invention is further illustrated with reference to the following figures and examples.
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and those skilled in the art can obtain other embodiments without inventive effort based on the embodiments of the present invention, and all embodiments are within the protection scope of the present invention. In addition, all the connection/connection relations referred to in the patent do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection auxiliary components according to specific implementation conditions. All technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
First, the following terms are explained:
GEO satellite: GEO, i.e., geostationary orbit (or "geostationary orbit", "geostationary satellite orbit"), refers specifically to a perfectly circular geostationary orbit of a satellite or satellite at an elevation of 35786 kilometers above the earth's equator. An observer on the earth surface can always observe the GEO satellite at the same position in the sky at any time, and can find that the satellite is still in the sky.
Satellite network control center: the satellite network management system is located, can manage and distribute the satellite network resource, and has the function of a communication system gateway.
User authentication: the user authentication is one kind of authentication of mobile phone information, including user state authentication and user personalized authentication, and is mainly used for identifying legal users and refusing illegal users to access the network.
Authentication: refers to verifying that the user has the right to access the system. Traditional authentication is verified by means of a password.
The satellite mobile phone is used for carrying out telephone service through a mobile communication satellite (such as a maritime satellite, an iridium satellite and a satellite of 'heaven-earth' in China), the satellite is specially designed for the mobile communication service, a telephone line design mode is adopted during the satellite design, a narrow-bandwidth multi-path telephone mode is adopted, a lower frequency band (an L frequency band or an S frequency band, 1-2GHz) is used, a customized user mobile phone can be directly communicated with the satellite, and in this mode, the satellite telephone dialing is the same as the normal land telephone dialing, and an opposite side can display the number of the opposite side at the incoming call.
However, the high-flux GEO satellite is different from the satellites, the high-flux GEO satellite has a high frequency band, and a mobile phone cannot directly communicate with the high-flux GEO satellite and directly dial a telecommunication mobile phone. Because of this problem with high throughput GEO satellites, there are some ways to make satellite calls using VOIP. The principle is that an APP of VOIP is installed on a mobile phone (or the mobile phone is installed when leaving factory), a user dials a satellite phone through the APP, the APP sends information of the opposite party to be dialed to a machine room of a satellite operator on the land through a satellite broadband network, the machine room is communicated with a ground phone network, the machine room dials the opposite party phone in the ground phone network according to the phone number of the target user transmitted by the APP, and after the call is established, the machine room serves as a transfer to connect the call of the user who initiates the call with the call of the target user.
Although the mode can support a user of a high-flux satellite to dial a telephone to other mobile phone users, the user who initiates a telephone call is a ground machine room, the number is also of the machine room, a target user can only dial the telephone number to the machine room when dialing the telephone number, and the machine room manages all users of the whole satellite network and does not know who dials the telephone number, so that the target user cannot find the user who originally initiates the call when dialing the telephone number.
Therefore, an implementation method needs to be designed in the high-throughput GEO satellite network, so that a user can make a voice call with an opposite party by dialing the opposite party, and an original initiator of the call can be found when the opposite party dials back the number.

s30, the called user terminal 10 displays the telephone number of the calling user terminal 10 assigned by the satellite consumer intelligent terminal 20;
s40, when the called user terminal 10 dials back the phone number to the user terminal 10 initiating the call, the satellite consumer intelligent terminal 20 determines and finds the corresponding user terminal 10 according to the binding relationship between the phone number and the user terminal 10, and transmits the call information to the user terminal 10 through the WIFI link to establish a call link.
As shown in fig. 2, the satellite consumer intelligent terminal 20 includes a WIFI transfer telephone number module 201, an authorized number encryption module 202, and an authentication and registration module 203, which are connected in sequence; therefore, the step S20 specifically includes the following steps:

When a telephone call occurs, the destination user's terminal will display the telephone number assigned by the satellite consumer smart terminal 20 to the user originating the call.
When the destination user dials back the telephone number to find the original user who initiated the call, the telephone network finds the satellite consumer intelligent terminal 20 through the satellite network control center 40 and the satellite link according to the telephone number, and the satellite consumer intelligent terminal 20 can judge which user is found according to the one-to-one correspondence relationship between the telephone number stored in the machine and the user. The call information is then transmitted to the user over a WiFi link, and when the user chooses to answer, a WiFi voice link is established and connected to the destination user via a satellite telephone link.
