Voice data may then be transmitted to the destination border gateway module via the communication link between the source, head office and destination telephone offices such that the destination border gateway module transmits the voice data to the destination subscriber (i.e., the second subscriber).
In another alternative embodiment, as shown in fig. 3 and 4, the system further comprises: and a voice scheduling module.
And the voice scheduling module is connected with the border gateway module and is used for processing voice services between satellite networks through the target mechanism.

The specific process of voice service in the network is described as follows: a user 1 in the narrow-band satellite network 1 makes a call to a user 2 based on an original voice service system in the narrow-band satellite network 1.
When the system is used for carrying out internetwork service, two service types are included: internetwork data traffic and internetwork voice traffic.
The specific process of internetwork data service is described as follows:
a user 1 in a broadband satellite network 1 sends data to a border gateway module 1 through an original data service system, wherein the data comprises a self ID (11), a target user ID (32) and data (data) to be sent;
the border gateway module 1 inquires the ID/IP corresponding table of itself to obtain 1.0.0.1 IP of the source user; inquiring the IP of the target user from the network management module by using the ID (32) to obtain 3.0.0.2 IP of the target user;
the border gateway module converts data to be sent into an IP format, and transmits the data through the Internet, wherein the source IP is 1.0.0.1, and the destination IP is 3.0.0.2;
the data service reaches the border gateway module 3 through the internet, the border gateway module inquires the ID/IP corresponding table of the border gateway module, and the user ID corresponding to 3.0.0.2 is 32;
the border gateway module 3 sends data in an IP format to the user 2 through the original data service system.
The specific process of inter-network voice service is described as follows:
subscriber 1 within narrowband satellite network 1 places a call to subscriber 2 within narrowband satellite network 2, at which time a voice link as shown in figure 9 will be established.
Specifically, the border gateway module 2 establishes a communication link between the border gateway module 2 (i.e., the current border gateway module) and the border gateway module 4 (i.e., the destination border gateway module) through the telephone exchange 2 (i.e., the first mechanism), the telephone exchange (i.e., the second mechanism), and the telephone exchange 4 (i.e., the third mechanism) in the case of acquiring the inter-network voice service of the user 1 (i.e., the user 21). Voice data may then be transmitted to border gateway module 4 via the communication link between telephone office 2, the central telephone office, and telephone office 4 such that border gateway module 4 transmits the voice data to subscriber 2 (i.e., 42).
