Background
With the popularization of mobile phones, the advent of the 4G era, IP (Internet Protocol ), VoLTE (voice over Internet Protocol) technology, and the birth of IMS voice service based technology, the information communication mode is spread all over the world today, and an extensible network communication platform with high flexibility and high reliability is formed. From the VoLTE infrastructure and value added application services of operators, electronic commerce of companies to the Internet of individual users, human life and work are changing.
The video telephone is a multimedia communication service integrating images and voices, and can realize face-to-face communication of people. The VoLTE 4G network provides high-definition voice calls and high-quality video calls, wherein the VoLTE voice calls have the characteristics of high telephone establishing speed, clear voice and the like, meanwhile, the telephone and the load bearing used by the internet surfing function are both supported by the IMS data network, so that the telephone and the internet can be used simultaneously without mutual influence, when the VoLTE video calls are initiated, firstly, the two parties need to establish a special load bearing channel through a calling process to control the transmission analysis and the like of rtp (Real-time Transport Protocol) data, and then, through the interaction of the rtp data, the two parties can carry out video calls. Compared with the video phone picture and tone quality of the prior video app (Application), the voice over long term evolution (VoLTE) video phone IMS service is clearer and is smoother and more stable in the call process.
While enjoying the advantages of VoLTE telephony, users have highlighted the problem of personal privacy, and therefore many terminals of video telephony are provided with functions of muting, transmitting alternative pictures, or pausing image transmission, etc., to protect user privacy. However, there is a need for precaution, that is, most of the existing terminals provide a function of recording images or voices of the other party, so that the other party may record or record the images or voices without the user's knowledge, and personal privacy is violated. It is therefore necessary to prevent the user from being unknowingly recorded with images or voices.
At present, aiming at a video telephone of a 3G network, a solution proposes a video protocol, a special frame is inserted into rtp video data transmitted to represent a recording request, an opposite terminal analyzes the rtp video data after receiving the rtp video data, and identifies whether the rtp video data is the opposite terminal requesting recording according to the inserted frame, and a request result is also replied in the rtp video data, and the specific steps are as follows:
1. a recording direction recorded party sends a recording prompt and a recording request command;
2. the user of the recorded party displays the recording prompt given by the recording party;
3. if the terminal of the recorded party supports parsing, the request command is parsed out, and whether recording is requested or not is replied to the recorded party.
Although the above solution can play a role in protecting personal privacy in video telephony, the following disadvantages still exist: the original video data is changed by the sent recording request, a receiver needs to analyze whether all rtp data have the recording request command, the efficiency is greatly reduced, and meanwhile, the special rtp data needs to be used to ensure that the network cannot be discarded because the rtp data do not support the analysis.
Therefore, there is a need for a recording control method in real-time communication, a real-time communication system and a communication terminal to overcome the above-mentioned disadvantages.

Detailed Description
The present invention will be described in more detail with reference to the accompanying drawings, which are included to illustrate embodiments of the present invention.
Referring to fig. 1, the present invention provides a method for controlling information recording in real-time communication, including the following steps:
s1, the recording party triggers the recording command in the real-time communication, for example, the recording party presses the recording button of the communication terminal during the real-time communication, thereby triggering the recording command.
And S2, automatically generating a recording request DTMF code stream according to the current call type of the real-time communication, and sending the recording request DTMF code stream to the recorded party of the real-time communication, wherein the current call type is a voice call or a video call, and the recording request DTMF code stream is a voice recording request DTMF code stream or a video recording request DTMF code stream. Specifically, if the current call type of the real-time communication is a voice call, the automatically triggered recording request DTMF code stream is 5999, and if the current call type of the real-time communication is a video call, the automatically triggered recording request DTMF code stream is 5977; and then the communication terminal of the recording party sends the recording request DTMF code stream in a normal DTMF code stream mode, and the real-time communication interface of the recording party is still a normal real-time communication interface without changing.
And S3, the recorded party receives the DTMF code stream of the recording request and analyzes the corresponding recording request to prompt the recorded party. Specifically, after receiving the DTMF code, the recorded party starts to perform analysis, and since the DTMF code stream is transmitted as a one-bit DTMF code, that is, the analysis of the recorded party is incomplete code stream analysis, after receiving the first-bit DTMF code in the recording request DTMF code stream, the recorded party needs to continue to wait for the subsequent DTMF code, and when no other DTMF code is received within the predefined time, the recorded party performs original processing according to the received first-bit DTMF code; and when all DTMF codes in the recording request DTMF code stream are received within the predefined time, prompting according to a recording request corresponding to the recording request DTMF code stream. In this embodiment, when the DTMF code received by the recorded party is 5, if there is no other code stream within 500ms, the original processing is performed according to the DTMF code of 5, if all the DTMF codes received within 500ms are completely received, that is, the DTMF code stream received within 500ms is 5999 or 5977, the prompt is performed on the real-time communication interface of the recorded party according to the recording request corresponding to the received 5999 or 5977DTMF code stream, for example, the real-time communication interface of the recorded party displays "the other party requests to record audio, whether to accept" or "the other party requests to record video, whether to accept" is displayed.
And S4, the recorded party selects whether to accept the recording request according to the prompt, and feeds back the selection result to the recording party. Specifically, the result of the selection is a response DTMF code stream different from the voice recording request DTMF code stream and the video recording request DTMF code stream in step S2, for example, the response DTMF code stream selected by the recording party to accept the recording request is 65, the response DTMF code stream selected by the recording party to reject the recording request is 55, and after the recording party selects to accept or reject the recording request, the corresponding response DTMF code stream is automatically generated and fed back to the recording party.
S5, when the recording request is accepted by the recorded party as a result of the selection received by the recording party, starting recording the real-time communication; s6, automatically generating a DTMF code stream to be recorded, sending the DTMF code stream to the recorded party, so as to prompt the recorded party, where the DTMF code stream to be recorded is, for example, 5957, and the DTMF code stream to be recorded is analyzed after being received by the recorded party, and a corresponding prompt (e.g., "the other party starts recording") is displayed on a real-time communication interface of the recorded party; s7, when the recording party finishes recording the real-time communication, automatically generating a recording-ending DTMF code stream, sending the recording-ending DTMF code stream to the recorded party, so as to prompt the recorded party, where the recording-ending DTMF code stream is, for example, 5989, and the recording-ending DTMF code stream is analyzed after being received by the recorded party, and displays a corresponding prompt (such as "the other party finishes recording" or "the other party stops recording") on a real-time communication interface of the recorded party.
S8, when the recording party receives the selection, prompting the recorded party to reject the recording request on the real-time communication interface of the recording party, specifically, when the recorded party selects to reject the recording request, automatically generating a response DTMF code stream (e.g. 55) to feed back to the recording party, and the recording party receiving the response DTMF code stream and parsing out the response information to display the corresponding prompt (e.g. "the other party rejects recording") on the real-time communication interface of the recording party; s9, the recording party ignores the recording command in step S1 and continues or ends the real-time communication.
It should be noted that, in the above real-time communication, any DTMF code stream between the recording party and the recorded party is transmitted by one bit, and the recording party and the recorded party both perform incomplete DTMF code stream analysis after receiving the corresponding DTMF code streams.
According to the information recording control method in real-time communication, once a recording party triggers a recording command in real-time communication, a DTMF code can be automatically used to generate a recording request DTMF code stream and the recording request DTMF code stream is sent to a recorded party, and the DTMF transmission belongs to a standard protocol and does not need to be modified, so that the DTMF transmission network can ensure end-to-end safe transmission of the recording request, and the problem that the rtp data of the recording request in the prior art is discarded because the rtp data of the recording request does not support analysis can not be solved; the sent recording request does not change the original voice data or video data of real-time communication, a receiver can know whether the recording request exists only by analyzing the DTMF code stream, and the receiver does not need to analyze whether all rtp data have the recording request command like the prior art, so that the efficiency is greatly improved; further, the recorded party can receive a prompt after the recording party triggers the recording command, and can choose to accept or reject the recording of the recording party, so that the user privacy of the recorded party can be protected.
Referring to fig. 2, the present invention further provides a real-time communication system, which includes a recording request generating unit 201, a DTMF code stream receiving unit 202, a real-time communication interface 203, and a result feedback unit 204.

Specifically, if the current call type of the real-time communication is a voice call, the automatically triggered recording request DTMF code stream is 5999, and if the current call type of the real-time communication is a video call, the automatically triggered recording request DTMF code stream is 5977.
The DTMF code stream receiving unit 202 is configured to receive and analyze all DTMF code streams in real-time communication, and display corresponding information or prompts in the real-time communication interface 203 according to an analysis result. Wherein, because the DTMF code stream is transmitted by one-bit DTMF code, the analysis of the DTMF code stream receiving unit 202 is incomplete code stream analysis, so after receiving the first-bit DTMF code, it needs to continue waiting for the subsequent DTMF code, when no other DTMF code is received within the predefined time, it does the original processing according to the received first-bit DTMF code; and when all DTMF codes of the corresponding DTMF code stream are received within the predefined time, prompting according to the information corresponding to the corresponding DTMF code stream. For example, when the received DTMF code is 5, if there is no other code stream within 500ms, the original processing is performed according to the DTMF code of 5, if all DTMF codes of the recording request DTMF code stream are received within 500ms, for example, 5999 or 5977, a prompt is performed in the real-time communication interface 203 according to the recording request corresponding to the received recording request DTMF code stream, for example, "the other party requests to record audio, whether to accept" or "the other party requests to record video, whether to accept" is displayed in the real-time communication interface.
The real-time communication interface 203 is configured to display call information and related prompts of the real-time communication and provide an operation interface for selecting whether to accept a recording request analyzed by the DTMF code stream receiving unit 202 from a corresponding recording request DTMF code stream, where the related prompts displayed in the real-time communication interface include the recording request analyzed by the DTMF code stream receiving unit 202 and a prompt when the recording request corresponding to the recording request DTMF code stream sent by the recording request generating unit 201 is rejected.
The result feedback unit 204 is configured to feed back a selection result of whether to accept the recording request analyzed by the DTMF code stream receiving unit 202 to a corresponding recording party, and enable recording of the real-time communication to start after the recording request corresponding to the recording request DTMF code stream sent by the recording request generating unit 201 is accepted. The selection result is a response DTMF code stream different from the voice recording request DTMF code stream and the video recording request DTMF code stream generated by the recording request generation unit 201, for example, when the recording request is received, after the real-time communication interface 203 selects to accept the recording request, the response DTMF code stream automatically generated by the result feedback unit 204 is 65, and after the real-time communication interface 203 selects to reject the recording request, the response DTMF code stream automatically generated by the result feedback unit 204 is 55.
The result feedback unit 204 is further configured to, when the recording request sent by the recording request generation unit 201 is received and the real-time communication starts to be recorded, automatically generate a DTMF code stream that starts to be recorded and send the DTMF code stream to the recorded party to prompt the recorded party, and when the real-time communication is finished to be recorded, automatically generate a DTMF code stream that finishes to be recorded and send the DTMF code stream to the recorded party to prompt the recorded party.
Referring to fig. 3, the present invention further provides a communication terminal, including a recording button 21, a communication module 22, a display 23, a microphone 24, a speaker 25, and the real-time communication system 20, where the recording button 21 is used to trigger a recording command in real-time communication, the communication module 22 is used to implement receiving and sending of data of the real-time communication system 20, including all DTMF code streams, voice data of a call, and video data of a call, and the microphone 24 is used to collect sound required by the real-time communication system 20; the loudspeaker 25 is used for playing the sound of the real-time communication system 20; the display 23 is used for displaying a real-time communication interface of the real-time communication system 20. The communication terminal further comprises a camera 26 for acquiring images required by the real-time communication system 20.
From the above, the real-time communication system and the communication terminal of the present invention support the transmission of DTMF codes, have a wide application range, for example, can be applied to 2G/3G/VoLTE telephone communication, once the recording party triggers the recording command in its real-time communication, the DTMF codes can be automatically used to generate the recording request code stream and send it to the recorded party, so as to ensure the end-to-end safety transmission of the recording request, and the problem that the rtp data of the recording request in the prior art does not support the analysis and is discarded can not occur, and the sent recording request does not change the voice data or video data of the original real-time communication, and the receiving party can know whether there is the recording request only by analyzing the DTMF code stream, and does not need to analyze all rtp data as in the prior art and whether there is the recording request command, so; more importantly, the recorded party can receive a prompt after the recording party triggers the recording command, and can choose to accept or reject the recording of the recording party, so that the user privacy of the recorded party can be protected.
