[0037] In mobile communication services, tracing refers to accurately locating the user's physical location through mobile communication technology and meeting government regulatory requirements. This is also an inevitable requirement for the commercialization of mobile communication services. In voice call services such as VoLTE / VoNR accessed through base stations, telecom operators conduct tracing work through wireless cells covered by base stations with cell-level accuracy. Satellite-based voice call services (Voice over Satellite, VoSat) integrate VoWiFi technology with high-throughput satellite communication networks. It is a new type of satellite network voice call solution that can solve the problem of voice calls and SMS sending and receiving in network-free scenarios such as complex terrain, aviation and navigation. However, in the VoSat service, users access the network through satellite terminal Wi-Fi. When making voice calls and sending and receiving text messages, they cannot locate the user's address through the base station like the VoLTE / VoNR service. Therefore, how to realize user positioning in satellite communications and improve positioning accuracy has become a technical problem that needs to be solved urgently.

[0038] In view of this, the embodiments of the present disclosure provide a location tracing method and related equipment for VoWiFi voice services based on satellite communication. By converting the public network address of the session request into an intranet address and obtaining the physical address of the satellite based on the intranet address, the user positioning of the satellite voice call service can be achieved, so that the VoSat service meets regulatory requirements and further promotes the commercial use of the VoSat service. Compared with the VoLTE / VoNR user location positioning, the present disclosure is advanced and has higher user location positioning accuracy, and the tracing accuracy is accurate from the cell level to the AP level.

[0039] See also Figure 3 , Figure 3The schematic flow chart of the location tracing method of the VoWiFi voice service based on satellite communication according to the embodiment of the present disclosure is shown. The location tracing method of the VoWiFi voice service based on satellite communication according to the embodiment of the present disclosure can be applied to the satellite tracing gateway and can be deployed on the server side. Figure 3 In the method 300 for tracing the location of the VoWiFi voice service based on satellite communication may further include the following steps.

[0040] In step S310, in response to receiving a location tracing request regarding a session request, a corresponding intranet address and intranet port number are determined based on the public network address and public network port number of the session request in the location tracing request.

[0041] The session request may be a VoWiFi voice service initiated by a user terminal. Figure 4 , Figure 4 A schematic diagram of a method for tracing the location of a VoWiFi voice service according to an embodiment of the present disclosure is shown. Figure 4 In the process, the user terminal UE can initiate a session request, which will land at the gateway after passing through the satellite network. The satellite ground network equipment will perform NAT conversion, allocate a public IP and service port number for its session, and then route it to the evolved packet data gateway (evolved Packet Data Gateway, ePDG) through the three-layer network.

[0042] In some embodiments, the public network address and the public network port number of the session request are obtained by performing network address relationship conversion on the session request; and the location tracing request is generated based on the public network address and the public network port number of the session request.

[0043] Among them, network address relationship translation can be used to rewrite the IP address in the IP data packet header. When the external network sends a data packet to the internal host, the NAT device checks the destination IP address of the data packet. If the destination IP address is a public IP address on the NAT device and the port number matches an entry in the NAT table, the NAT device changes the destination IP address of the data packet to the corresponding internal private IP address, and may also change the destination port number (if it is NAPT). When the internal host sends a data packet to the external network, the NAT device checks the source IP address of the data packet. If the address is private, the NAT device replaces the source IP address with a public IP address, and may also change the source port number (if it is NAPT). This conversion is recorded in the NAT table (i.e., the preset network address relationship) so that subsequent data packets can be correctly returned to the corresponding internal host. Figure 4In the process, the session request can be routed through the packet data gateway to the telecommunications tracing gateway, which generates a location tracing request based on the public network address and public network port number of the session request, and sends the location tracing request to the satellite tracing gateway.

[0044] In some embodiments, the public network address and public network port number of the session request are routed from the satellite ground network device via the network routing and packet data gateway to the telecommunications tracing gateway, and the location tracing request is generated at the telecommunications tracing gateway.

[0045] Specifically, the satellite ground network equipment allocates an intranet IP and an intranet port number to the session request, and the session request will be allocated a public IP and a public port number when it passes through the Internet exit of the satellite ground. The process of converting the intranet IP and the intranet port number to the public IP and the public port number is called network address relation translation (NAT translation). Figure 4 In the method 300, the execution subject can be a satellite tracing gateway. The satellite tracing gateway uses the public network IP and port number as indexes to query the intranet IP and port number of the session according to the NAT relationship table synchronized by the satellite ground equipment. Then, the internally stored terminal information is queried with the intranet IP as the index to obtain the MAC address of the satellite terminal that initiated the service. The VoSat voice call request initiated by the UE lands at the gateway after passing through the satellite network. The satellite ground system network equipment performs NAT conversion, assigns a public network IP and service port number to its session, and then routes it to the evolved packet data gateway through a three-layer network. The telecommunications tracing gateway calibrates the VoSat voice session request through the public network IP and port number, and initiates a tracing request to the satellite tracing gateway.

[0046] In some embodiments, determining the corresponding intranet address and intranet port number based on the public network address and public network port number of the session request in the location tracing request includes:

[0047] The intranet address and the intranet port number are obtained by querying in a preset network address relationship based on the public network address and the public network port number.

[0048] The preset network address relationship may include a mapping relationship between a public network address and a public network port number, and an intranet address and an intranet port number. For example, the preset network address relationship may be a NAT table.

[0049] In step S320, the MAC address of the satellite terminal corresponding to the session request is obtained based on the intranet address and the intranet port number.

[0050] The MAC (Media Access Control) address of the satellite terminal may refer to a unique identifier or hardware address of a network interface card (NIC) on the terminal device.

[0051] In some embodiments, obtaining the physical address of the satellite terminal corresponding to the session request based on the intranet address and the intranet port number includes:

[0052] The physical address of the satellite terminal is retrieved from the locally stored satellite terminal information based on the intranet address and the intranet port number.

[0053] Specifically, Figure 4 As shown, the satellite tracing gateway can initiate a MAC address acquisition request to the BOSS platform based on the MAC address. Among them, the BOSS platform returns the status and geographic location information of the satellite terminal to the satellite tracing gateway. Among them, the high-throughput satellite business operation support system (Business Operation Support System, BOSS) as one of the components of the satellite ground system stores VoSat service registration information and terminal information.

[0054] In step S330, the geographical location information of the satellite terminal is acquired based on the MAC address of the satellite terminal to obtain a location tracing result of the session request.

[0055] The geographic location information of the satellite terminal may refer to the latitude and longitude information of the satellite terminal.

[0056] In some embodiments, acquiring the geographical location information of the satellite terminal based on the MAC address of the satellite terminal to obtain the location tracing result of the session request includes:

[0057] Generate a location tracing request based on the MAC address of the satellite terminal, and send the location tracing request;

[0058] A response result to the location tracing request is received, the response result including geographic location information, and a location tracing result of the session request is obtained.

[0059] Furthermore, in some embodiments, the corresponding result may also include the state of the satellite terminal, wherein fault troubleshooting may be performed based on the state of the satellite terminal.

[0060] In some embodiments, method 300 further includes: sending the location tracing result to the initiator of the session request.

[0061] Specifically, the satellite tracing gateway returns the geographic location information to the telecommunications tracing gateway to complete the tracing process. The telecommunications tracing gateway can return the location tracing result to the user terminal UE.

[0062] It can be seen that according to the embodiments of the present disclosure, the location tracing of VoWiFi voice services based on satellite communication can be realized, so that VoSat services meet regulatory requirements and further promote the commercial use of VoSat services. Compared with VoLTE / VoNR user location positioning, the present disclosure is advanced and has higher user location positioning accuracy, and the tracing accuracy is accurate from the cell level to the AP level.
