Those of ordinary skill in the art will recognize that various changes and modifications of the examples described herein can be made without departing from the spirit and scope of the invention.
Fig. 1 shows a schematic block diagram of a routing device for routing user data in voice communication of a satellite internet system according to an embodiment of the invention.
In fig. 1, a routing device 1 for routing user data in voice communication of a satellite internet system is shown, the routing device 1 is connected to a user terminal 2 via a satellite internet NT1, here N user terminals are shown, where N is a natural number greater than or equal to 1, hereinafter simply referred to as user terminal 2 without particularly distinguishing between the individual user terminals. The routing device 1 is also connected to a public network Domain Name System (DNS) server 13 and a voice communication gateway server 14 via the internet. The public network DNS server 13 provides DNS services to devices in the internet. The voice communication gateway server 14 is an interface gateway between voice service and internet, and is a necessary network element in an untrusted Wi-Fi network access mode. In one embodiment, the voice communication gateway server 14 is an evolved packet data gateway (ePDG) server.
The routing device 1 comprises a core routing module 121, a DNS query module 122 and a subscription operator database module 123.
The contracted carrier database module 123 stores information about more than one contracted carrier. In one embodiment, the subscription operator related information includes a mobile signal country code (MCC), a mobile network number (MNC), and/or a public network IP address of the voice communication gateway server. Fig. 4 is a diagram schematically showing an example of the related information of the contracted carrier. It should be understood that the content contained in the related information of the subscription operator is not limited thereto, and those skilled in the art can select according to actual needs.
When receiving the DNS request from the user terminal 2, the core routing module 121 determines whether the DNS request is a DNS request of a VoWiFi (Voice over WiFi) service, and if it is determined that the DNS request is a DNS request of a VoWiFi service, forwards the DNS request to the DNS query module 122.
When receiving the DNS request from the core routing module 121, the DNS query module 122 searches the subscription operation information database module 123 to determine whether or not a subscription operator matching the operator included in the received DNS request is stored in the subscription operator database module 123, and if it is determined that a subscription operator matching the operator included in the DNS request is stored in the subscription operator database module 123, returns the public network IP of the voice communication gateway server of the matching subscription operator to the user terminal 2.
According to the routing device disclosed by the invention, the service can be provided for the VoWiFi user of the contracted operator in the VoWiFi voice service based on the broadband satellite system, and the user is not influenced by using other satellite Internet data services.
In another embodiment, when the core routing module 121 determines that the DNS request is not a DNS request for VoWiFi traffic, the DNS request for non-VoWiFi traffic is forwarded to a public network DNS server.
In one embodiment, the user terminal 2 is connected by WIFI to a satellite terminal device (not shown) that is in communication with the satellite and transmits the DND request of the user terminal 2 to the satellite, which is in communication with the routing device 1 and transmits the DND request of the user terminal 2 to the routing device 1.
In one embodiment, the routing device 1 may be integrated with a satellite ground system gateway station.
Fig. 2 shows a flow chart of a routing method for routing user data in voice communication of a satellite internet system according to an embodiment of the present invention.
As shown in fig. 2, in step S201, a DNS request from the user terminal 2 is received.
Next, in step S203, it is determined whether the DNS request received in step S201 is a DNS request of VoWiFi service.
If it is determined that the DNS request is a DNS request for the VoWiFi service (i.e., if the determination in step S203 is yes), the contracted carrier database module 123 is searched in step S205 to determine whether or not a contracted carrier matching the carrier included in the DNS request received in step S201 is stored in the contracted carrier database module 123.
Next, when it is determined in step S205 that the contracted carrier matching the carrier included in the DNS request received in step S201 is stored in the contracted carrier database module 123 (that is, when it is determined in step S205 that the carrier is yes), the public network IP of the voice communication gateway server 14 of the matched contracted carrier is returned to the user terminal 2 in step S211.
According to the routing method, the service can be provided for the VoWiFi user of the contracted operator in the VoWiFi voice service based on the broadband satellite system, and the user is not influenced by using other satellite Internet data services.
In one embodiment, when it is determined in step S203 that the DNS request is not a DNS request for VoWiFi service, the DNS request for non-VoWiFi service is forwarded to the public network DNS server in step S209.
Fig. 3 shows a flow chart of a routing device for routing user data in a voice communication of a satellite internet system according to an embodiment of the invention.
As shown in fig. 3, in step S301, a DNS request from the user terminal 2 is received.
Next, in step S302, the core routing module 121 determines whether the DNS request received in step S301 is a DNS request of VoWiFi service. If it is determined in step S302 that the DNS request received in step S301 is a DNS request for the VoWiFi service (yes in step S302), the flow proceeds to step S303. Otherwise, the process advances to step S306.
In step S303, the DNS request is transferred to the DNS query module 122.
Next, in step S304, the DNS query module 122 searches the subscription operation information database to determine whether the operator is a subscribed operator. If the determination is yes, the flow proceeds to step S307, otherwise, the flow proceeds to step S305.
In step S305, the routing device 1 blocks the service request.
In step S306, the core routing module 121 routes the DNS request to a DNS server on the public network for resolution, and returns the result to the user terminal 2.
In step S307, the routing device 1 returns the ePDG public network IP address of the operator to the user terminal 2.
According to the routing method, the service can be provided for the VoWiFi user of the contracted operator in the VoWiFi voice service based on the broadband satellite system, and the user is not influenced by using other satellite Internet data services.
