[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] Reference Figure 1 , is a flowchart of an embodiment of an encrypted voice call method of the present application, comprising the following steps:

[0052] Step 101: Initiate a call request for a voice call, wherein the call request includes dialing information of the called party.

[0053] In the embodiment of the present application, the calling terminal is a customized terminal that supports the call type of encrypted voice calls. In one example, the call type of this encrypted voice call can be an encrypted VoLTE call. On the calling terminal, a dial pad can be set, and a secret call application corresponding to the call type of the encrypted voice call can be installed, and the calling terminal is connected to the service platform. The service platform can be a quantum security service platform, which is used to query the online status of each terminal, the secret call service status and other business status.

[0054] In step 101, a user initiates a call through the dial pad of the calling party, that is, initiates a call request for a voice call to the called party, and the call request includes the dialing information of the called party. In one embodiment, the voice call is an encrypted VoLTE call.

[0055] Step 102: Based on the dialing information of the called party, the service platform is called to query the service status of the called party.

[0056] In step 102, the calling end needs to call the service platform to query the service status of the called end according to the dialing information of the called end. In an optional embodiment, the calling end can call the service platform to query the service status of the called end through the pre-installed quantum security shield application. The service status of the called end that needs to be queried may include: whether the called end supports the call type of the voice call, whether the called end has a secret call application installed, whether the network voice call function of the called end is online, and other business status.

[0057] Step 103. When the service status of the called party meets the preset status, the call request and the conversion identifier are sent to the transcoding gateway, and the conversion identifier is generated according to the call type of the voice call and the call type of the voice call supported by the called party. The transcoding gateway is used to convert the voice call signaling in the call request into encrypted network voice call signaling according to the conversion identifier, and then forward the encrypted network voice call signaling to the called party.

[0058] In step 103, when the service status of the called end meets the preset status, the call request and the conversion identifier are sent to the transcoding gateway. In an optional embodiment, if the called end does not support the call type of the voice call initiated by the calling end, and a secret call application is installed on the called end, it meets the preset status. For example, if the calling end initiates an encrypted VoLTE call, the called end may be a terminal that does not support encrypted VoLTE calls, but a secret call application must be installed on the called end. Further, in this example, the called end can support VoLTE calls, but the called end does not support encrypted VoLTE calls.

[0059] After confirming that the service status of the called party meets the preset status, the call request carrying the conversion flag is sent to the transcoding gateway. The conversion flag is generated according to the call type of the voice call and the call type of the voice call supported by the called party. For example, if the calling party initiates an encrypted VoLTE call and the called party supports encrypted VoIP calls, the conversion flag is the VoLTE to VoIP flag.

[0060] The transcoding gateway is used to convert the voice call signaling in the call request into encrypted network voice call signaling according to the conversion identifier, and then forward the encrypted network voice call signaling to the called party. In one example, if the conversion identifier is a VoLTE to VoIP identifier, the transcoding gateway will decrypt the VoLTE voice call signaling in the call request and convert it into VoIP voice call signaling and then encrypt it, thereby sending the encrypted VoIP voice call signaling to the called party. In one embodiment, the call request carrying the conversion identifier is first sent to the IMS network (IP Multimedia Subsystem, i.e., the multimedia subsystem network in some embodiments of the present application), and the IMS network identifies the voice call signaling in the call request by identifying the conversion identifier, and then sends the voice call signaling to the transcoding gateway.

[0061] Step 104: After the called party receives the encrypted network voice call signaling, an encrypted voice call is performed with the called party.

[0062] In step 104, after the called end receives the encrypted network voice call signaling, an encrypted voice call is made with the called end. In an optional embodiment, after the encrypted network voice call signaling is received by the secret call application on the called end, the encrypted network voice call signaling is first decrypted to obtain a voice data packet, thereby realizing an encrypted voice call with the called end that has received the voice data packet. In an example, after the called end receives the encrypted VoIP voice call signaling, the calling end that initiates the encrypted VoLTE call can make a VoLTE to VoIP encrypted voice call with the called end.

[0063] In an embodiment of the present application, the calling end initiates a call request for a voice call, and the call request includes the dialing information of the called end; based on the dialing information of the called end, the service platform is called to query the service status of the called end; when the service status of the called end meets the preset status, the call request and the conversion identifier are sent to the transcoding gateway, and the conversion identifier is generated according to the call type of the voice call and the call type of the voice call supported by the called end. The transcoding gateway is used to convert the voice call signaling in the call request into encrypted network voice call signaling according to the conversion identifier, and then forward the encrypted network voice call signaling to the called end; after the called end receives the encrypted network voice call signaling, it conducts an encrypted voice call with the called end. The embodiment of the present application realizes the conversion of the voice call signaling in the call request into encrypted network voice call signaling by deploying the transcoding gateway, which not only opens up the direct communication channel between two different encrypted voice communication technologies, VoLTE and VoIP, but also ensures the encryption and decryption of the voice call signaling during the transmission process, thereby significantly improving the experience quality of encrypted voice calls between users using different encrypted voice communication technologies.

[0064] In an optional embodiment of the present application, when the service status of the called party meets the preset status, sending the call request and the conversion identifier to the transcoding gateway includes:

[0065] If the called end does not support the call type of the voice call and a secret call application is installed on the called end, the call request and the conversion identifier are sent to the multimedia subsystem network, and the secret call application is used to receive the network voice call signaling;

[0066] Controlling the multimedia subsystem network to identify the voice call signaling in the call request according to the conversion identifier;

[0067] The voice call signaling is sent to the transcoding gateway.

[0068] In this embodiment, if the called end does not support the call type of voice call, and the called end is installed with a secret call application for receiving network voice call signaling, it is determined that the service status of the called end meets the preset status. At this time, the call request and the conversion identifier are sent to the multimedia subsystem network (i.e., IMS network). In one example, if the calling end initiates an encrypted VoLTE call, the called end may be a terminal that does not support encrypted VoLTE calls, but the called end needs to have a secret call application installed.

[0069] After receiving the call request and the conversion identifier, the multimedia subsystem network identifies the voice call signaling that needs to be converted in the call request according to the conversion identifier, and then sends the voice call signaling that needs to be converted to the transcoding gateway. In one example, if the conversion identifier is a VoLTE to VoIP identifier, the multimedia subsystem network will identify the VoLTE voice call signaling in the call request according to the conversion identifier and send it to the transcoding gateway.

[0070] The embodiment of the present application identifies the voice call signaling that needs to be converted through the multimedia subsystem network, and sends these signaling to the transcoding gateway, and then converts the signaling type through the transcoding gateway to achieve encrypted voice calls between different voice communication technologies.

[0071] In an optional embodiment of the present application, after sending the voice call signaling to the transcoding gateway, the method further includes:

[0072] Controlling the transcoding gateway to decrypt the voice call signaling to obtain the decrypted voice call signaling;

[0073] Using the transcoding gateway to convert the decrypted voice call signaling into the network voice call signaling;

[0074] Encrypting the network voice call signaling to obtain the encrypted network voice call signaling;

[0075] The encrypted network voice call signaling is forwarded to the called party.

[0076] In this embodiment, the transcoding gateway needs to perform decryption, conversion, and encryption in the intermediate process. Specifically, after the transcoding gateway receives the voice call signaling, it first needs to decrypt the voice call signaling to obtain the decrypted voice call signaling; then use the transcoding gateway to convert the decrypted voice call signaling into network voice call signaling; finally, encrypt the network voice call signaling to obtain the encrypted network voice call signaling and forward it to the called party. In one example, if the conversion identifier is a VoLTE to VoIP identifier, the transcoding gateway will decrypt the VoLTE voice call signaling in the call request and convert it into a VoIP voice call signaling and then encrypt it, thereby sending the encrypted VoIP voice call signaling to the called party.

[0077] The embodiment of the present application uses a transcoding gateway to decrypt, convert, and encrypt voice call signaling and forward it to the called party. During the conversion process, the decryption and encryption of the voice call signaling ensures the security of the call content; the transcoding gateway realizes the conversion between different voice communication technologies. Even if the called party does not support a specific call type, it can receive the call request through the transcoding gateway.

[0078] In an optional embodiment of the present application, the performing an encrypted voice call with the called party includes:

[0079] Controlling the secret speech application on the called party to receive the encrypted network voice call signaling;

[0080] Decrypting the encrypted network voice call signaling to obtain a voice data packet;

[0081] Conduct an encrypted voice call with the called party that receives the voice data packet.

[0082] In this embodiment, the called end receives the encrypted network voice call signaling through the secret call application, and decrypts the encrypted network voice call signaling into plain text to obtain a normal voice data packet, so that the calling end can make an encrypted voice call with the called end that has received the voice data packet. In one example, after the called end receives the encrypted VoIP voice call signaling, it decrypts the encrypted VoIP voice call signaling into plain text to obtain a normal voice data packet, and the calling end that initiates the encrypted VoLTE call can make a VoLTE to VoIP encrypted voice call with the called end.

[0083] In the embodiment of the present application, the called party receives and processes encrypted network voice call signaling through the installed secret call application, which significantly improves the experience quality of encrypted voice calls between users using different encrypted voice communication technologies.

[0084] In an optional embodiment of the present application, when the service status of the called party meets the preset status, sending the call request and the conversion identifier to the transcoding gateway includes:

[0085] If the called end supports the call type of the voice call, sending the call request to the called end;

[0086] After the called party receives the call request, conducting an encrypted voice call with the called party;

[0087] or,

[0088] If the called party does not support the call type of the voice call and the called party has not installed the secret call application, changing the call request of the voice call to a common call request;

[0089] The common call request is sent to the called party to conduct a common voice call with the called party.

[0090] In this embodiment, if the called end does not meet the preset status, other types of voice calls can also be made. In the first case of this embodiment, if the called end supports the call type of the voice call initiated by the calling end, the call request is directly sent to the called end. After the called end receives the call request, the calling end can make an encrypted voice call with the called end. In one example, if the calling end initiates an encrypted VoLTE call and the called end also supports encrypted VoLTE calls, the call request can be directly sent to the called end to establish an encrypted VoLTE call between the calling end and the called end.

[0091] In the second case of this embodiment, if the called end does not support the call type of voice call and the called end has not installed the secret call application, the call request of the voice call is changed to a normal call request and then sent to the called end, and the calling end and the called end conduct a normal voice call. In one example, if the calling end initiates an encrypted VoLTE call, but the called end does not support encrypted VoLTE calls and has not installed the secret call application, the encrypted VoLTE call initiated by the calling end will fall back to a normal voice call, and finally a normal voice call will be conducted with the called end.

[0092] When direct communication between two different encrypted voice communication technologies cannot be achieved, the embodiment of the present application also provides the option of conducting other types of voice calls, and can flexibly adjust the call type according to the actual situation of the called party to ensure that the call can proceed smoothly.

[0093] In an optional embodiment of the present application, before sending the call request and the conversion identifier to the multimedia subsystem network, the method further includes:

[0094] Determine whether the network voice call function of the called party is online;

[0095] If the network voice call function of the called party is online, the call request and the conversion identifier are sent to the multimedia subsystem network.

[0096] In this embodiment, before sending the call request and the conversion identifier to the multimedia subsystem network, the online status of the network voice call function of the called party can also be judged. Specifically, the service platform or the quantum secret call service end can be called to query and judge whether the network voice call function of the called party is online. The quantum secret call service end is a platform that communicates with the secret call application of the called party. If the network voice call function of the called party is online, the call request and the conversion identifier are sent to the multimedia subsystem network, so as to perform subsequent operations such as conversion of signaling type.

[0097] Reference Figure 2 , is a system architecture diagram of an embodiment of an encrypted voice call method of the present application.

[0098] like Figure 2 As shown, when the calling party equipped with a VoLTE secret call dial initiates an encrypted VoLTE call, it calls the service platform to query whether the called party has installed the secret call application and whether the network voice call function is online. If the called party has installed the secret call application and the network voice call function is online, the call request and conversion identifier are sent to the IMS network, which routes the call and sends the VoLTE voice call signaling in the call request to the transcoding gateway for conversion to obtain encrypted VoIP voice call signaling. The encrypted VoIP voice call signaling is further sent to the VoIP secret call platform, which sends it to the secret call application of the called party. At this point, an encrypted voice call from VoLTE to VoIP is realized between the calling party and the called party.

[0099] The embodiment of the present application determines the online status of the called party and then sends a call request and a conversion identifier. Signaling conversion is performed only when it is confirmed that the called party is online, which can reduce call failures caused by the called party being offline.

[0100] In an optional embodiment of the present application, the performing an encrypted voice call with the called party includes:

[0101] Receive the heartbeat signal regularly reported by the called terminal.

[0102] In this embodiment, during the encrypted voice call, the called end needs to regularly report a heartbeat signal. In an optional embodiment, the called end can regularly report a heartbeat signal to the quantum encrypted call server through an encrypted call application.

[0103] In the embodiment of the present application, the called party periodically reports a heartbeat signal during a call, and can use the heartbeat signal to monitor the online status of the called party in real time, and promptly discover and handle possible connection problems.

[0104] Reference Figure 3 , is a voice call flow chart of an embodiment of an encrypted voice call method of the present application.

[0105] Figure 3 The specific implementation process of an encrypted voice call method of an embodiment of the present application is shown in FIG. The calling end is installed with a quantum security shield application, and the secret call application of the called end is connected to the quantum secret call server. This example shows an encrypted voice call from VoLTE to VoIP between the calling end and the called end. The specific steps are as follows:

[0106] Step 1.1: After the calling party initiates a call, the Quantum Security Shield application calls the service platform to query whether the calling and called parties have activated the VoLTE confidential call service.

[0107] Step 1.2: If the called party has not activated the VoLTE confidential call service, the relevant information is returned to the Quantum Security Shield application on the calling party.

[0108] Step 1.3: Use the Quantum Security Shield application to call the service platform to continue to query whether the called party has activated the VoIP secret message service.

[0109] Step 1.4: If the called party activates the VoIP secret message service, the relevant information is returned to the Quantum Security Shield application on the calling party.

[0110] Step 1.5: Check whether the VoIP service function of the called party is online through the quantum secret call server.

[0111] Step 1.6: If the called party's VoIP is online, relevant information is returned to the Quantum Security Shield application on the calling party.

[0112] Step 2.1: The call request from the calling party carrying the conversion identifier is first sent to the IMS network. The IMS network identifies the voice call signaling in the call request by identifying the conversion identifier, and then sends the voice call signaling to the transcoding gateway.

[0113] Step 2.2: The transcoding gateway decrypts, transcodes, and encrypts the voice call signaling, obtains the encrypted network voice call signaling, and sends the transcoded and encrypted network voice call signaling to the called party. The called party's secret call application is activated upon receiving the encrypted network voice call signaling, and enters the VoIP call interface; the calling party's UI (User Interface) is also refreshed to enter the encrypted voice call interface. During the encrypted voice call, the called party will periodically report heartbeats to the quantum secret call server.

[0114] In an embodiment of the present application, the calling end initiates a call request for a voice call, and the call request includes the dialing information of the called end; based on the dialing information of the called end, the service platform is called to query the service status of the called end; when the service status of the called end meets the preset status, the call request and the conversion identifier are sent to the transcoding gateway, and the conversion identifier is generated according to the call type of the voice call and the call type of the voice call supported by the called end. The transcoding gateway is used to convert the voice call signaling in the call request into encrypted network voice call signaling according to the conversion identifier, and then forward the encrypted network voice call signaling to the called end; after the called end receives the encrypted network voice call signaling, it conducts an encrypted voice call with the called end. The embodiment of the present application realizes the conversion of the voice call signaling in the call request into encrypted network voice call signaling by deploying the transcoding gateway, which not only opens up the direct communication channel between two different encrypted voice communication technologies, VoLTE and VoIP, but also ensures the encryption and decryption of the voice call signaling during the transmission process, thereby significantly improving the experience quality of encrypted voice calls between users using different encrypted voice communication technologies.
