Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Satellite internet systems typically include satellite terminals, satellite constellations, satellite terrestrial systems, and the like. The inventor thinks that, aiming at the characteristics of a satellite broadband communication system, the global coverage and the mobile access capability of a satellite internet terminal can be fully utilized by the fusion design of the ground VoWiFi (Voice over Wi-Fi) and the low-orbit satellite internet system, so that the application scene of the VoWiFi is expanded, and a better Voice solution is provided for the satellite internet system.
The inventor further researches and discovers that the traditional VoWiFi technology is mainly used for a ground network, a user uses a mobile phone terminal to access a fixedly-placed WiFi device, and the use area and the use scene are limited. Meanwhile, the user has higher requirements on the safety supervision capability in the problems of identification authentication and user position positioning of a satellite system and a ground network operator. The terminal used by the user is a hard terminal or a mobile phone connected with a network cable, and if the broadband satellite system is combined with the ground network based on the IP telephone technology, inconvenience is brought to the user, and the voice quality is difficult to ensure. In a low-orbit broadband satellite system which is being developed in the world, if a VoLTE (Voice over Long-Term Evolution) or VoNR (Voice over New Radio) method is adopted to realize a high-definition Voice communication function of a satellite terminal, one terminal can only provide one path of Voice dialing based on the number of the terminal, and the requirement that a plurality of users realize simultaneous multi-path Voice communication by using mobile phones and mobile phone numbers cannot be met, so that the use scene is limited.
In view of the above, the present invention provides a voice communication method to solve the above problems.
Some embodiments of the disclosed voice communication method are first described in conjunction with fig. 1.
Fig. 1 illustrates a flow diagram of a voice communication method of some embodiments of the present disclosure. As shown in fig. 1, the present embodiment includes steps S101 to S104.
In step S101, the user terminal connects to the satellite terrestrial system through the satellite terminal, and performs Wi-Fi authentication with the satellite terrestrial system.
The user terminal may specifically be a mobile phone terminal with a VoWiFi capability used by a user. In some embodiments, the user terminal may connect to the satellite terminal through a Wi-Fi signal transmitted by the satellite terminal and then connect to the satellite terrestrial system through a data link between the satellite terminal and the satellite terrestrial system. The data link is established in a mode that a satellite terminal tracks a satellite by using ephemeris on a millimeter wave frequency band and the satellite realizes data transparent transmission, and the satellite terminal and a satellite ground system are subjected to identity authentication based on a public key certificate.
For example, the satellite terminal and the satellite ground system can perform identity authentication of a public key certificate based on an elliptic curve password, so that the identity authentication is completed by performing multiple information interactions through a protocol on the premise of ensuring the security. And after the data link is established, the satellite terminal releases the Wi-Fi signal so that the user terminal can be connected with the satellite terminal through the Wi-Fi signal. In the Wi-Fi authentication process, the satellite terminal serves as an authentication system, the ground system serves as an authentication server, the satellite constellation only serves as a transparent transmission channel, and the satellite constellation does not participate in the authentication process.
In some embodiments, the user terminal may employ 802.1x protocols for Wi-Fi authentication with the satellite terrestrial system.
In step S102, the user terminal is connected to the core network element through the evolved packet data gateway, and performs core network access authentication with the core network element.
The ePDG (evolved Packet Data Gateway) may specifically be an evolved Packet Data Gateway dedicated to satellite access provided by an operator. The EPC (Evolved Packet Core, 4G Core Network) includes related devices such as a PGW (Public Data Network GateWay), an AAA (Authentication Authorization Accounting) Server, an HSS (Home Subscriber Server), a DRA (Diameter Routing Agent), and the like.
After the Wi-Fi authentication is completed, the user terminal can access the Internet through a satellite and a satellite ground system through a Wi-Fi signal connected with the satellite terminal, and then finds ePDG equipment through a preset Internet domain name so as to be subsequently accessed to an EPC (electronic product code) and IMS (IP Multimedia system) network of a telecom operator to realize voice communication service. For example, the EPC technology may be accessed using a NON 3GPP network (NON 3GPP network) in the 3GPP standard, through which a user terminal using a satellite terminal is accessed from the Internet to the EPC network.
In some embodiments, the user terminal and the network element of the core network may use an EAP-AKA (Extensible Authentication Protocol-Authentication and Key agent) Authentication algorithm for performing core network access Authentication. The user terminal can be used as an EAP authentication client, and an extensible identity authentication protocol EAP authentication message is encapsulated in a second version Internet key exchange protocol IKEv2 message; and sending the IKEv2 message to the ePDG according to the pre-configured IP address of the ePDG so that the ePDG decapsulates the IKEv2 message to obtain an EAP authentication message. The ePDG may serve as an EAP authentication agent, and encapsulates the EAP authentication message into a Diameter message for the AAA server to perform core network access authentication. The AAA server can process the Diameter message to complete the access authentication of the user terminal, and the HSS is used as a user subscription information server and can uniformly manage the user subscription and authentication parameter information.
In step S103, the ue connects to the IP multimedia system through the network element of the core network, and performs registration authentication with the IP multimedia system.
In some embodiments, the user terminal may perform registration authentication of the IP multimedia system with the IP multimedia system through a SIP (Session Initiation Protocol) message.
In step S104, the ue implements the calling and called connections in the voice communication through the IP multimedia system.
In the embodiment, the user terminal is connected with the satellite terminal and then respectively performs identity authentication with the satellite ground system, the core network element and the IP multimedia system, the calling and called functions are realized by using the local number after the identity authentication, voice mutual dialing can be performed with the in-network or the ground public network, the low complexity and reliable voice quality are realized, and therefore, the Wi-Fi-based voice communication service is conveniently and reliably provided for a plurality of user terminals through the satellite communication system.
Meanwhile, the embodiment also designs the access authentication of the user terminal in the satellite ground system and the identity authentication of the user terminal in the mobile operator, and the combination of the satellite communication system and the ground network is realized by using the schemes of 3GPP S2b and the like based on the VoWiFi technology, so that the satellite communication system can be applied to the mobile satellite terminal with the Wi-Fi access function, and the satellite mobile communication system can provide the VoWiFi service with global seamless coverage.
