Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a calling ring back tone interaction method based on dynamic video identity authentication. Background Art

[0002] In traditional ringback tone services, the called user can only identify the caller's identity through the incoming call number or the text name in the yellow pages. The calling user cannot actively push identity authentication information to the called user, and the ringback tone platform lacks a reliable verification mechanism for the caller's identity.

[0003] The following problems exist in the existing technology: 1. Identity authenticity cannot be verified: the caller number can be easily forged by dialing software, and it is difficult for the called user to distinguish whether the call is a fraud or harassment call; 2. Information display is single and inefficient: static text / name cannot intuitively convey the caller's identity background (such as occupation, relationship), resulting in the called user needing to make additional inquiries or guess the caller's intention; 3. Lack of interactive capabilities: the calling user cannot dynamically select identity display content based on the called user's relationship, and traditional ringtones only support one-way fixed content push; 4. Poor terminal compatibility: the existing video ringtone technology is not adapted to the performance of different terminals, and is prone to problems such as playback freeze and blurred image quality, affecting the user experience. Summary of the Invention

[0004] The purpose of the present invention is to address the problem in current telecommunications scenarios where only numbers or yellow pages names are displayed for unfamiliar incoming calls, and the authenticity of the caller's identity cannot be quickly verified. The present invention provides a calling ringback tone interaction method based on dynamic video identity authentication. By introducing a unique token verification mechanism into the calling ringback tone process, the calling user can select and push the authenticated identity video to the called terminal in real time when dialing, and intuitively display the caller's identity background (such as occupation, relationship, etc.) in the form of dynamic video, solving the pain point of the called user refusing to answer the call or suffering from fraud and harassment due to the inability to identify the caller's intention, while improving the calling user's call credibility and the called connection rate.

[0005] The technical solution adopted in the present invention is: A caller ringback tone interaction method based on dynamic video identity authentication is as follows: the ringback tone platform performs trustworthy authentication on the caller number in the call and pushes an identity selection video to the caller; the caller makes a key selection according to the prompt of the identity selection video, and the ringback tone platform obtains the authenticated caller identity authentication video according to the key information of the calling terminal. The ringback tone platform pushes the authenticated caller identity authentication video to the called party to complete the ringback tone interaction.

[0006] Furthermore, the method specifically includes the following steps: Step 1: The calling terminal initiates a call through the APP, and the APP simultaneously sends the unique token corresponding to the call to the service management center of the ringback tone platform; Step 2: The CRBT platform determines whether the calling user has activated the CRBT service. If so, the CRBT platform intercepts the calling call signaling and executes step 3. Otherwise, the CRBT platform uses the existing process to process the calling call. Step 3: The signaling process verifies the call token to the service management center. If the token verification is successful, the ringback tone platform pushes the caller identity selection video to the calling mobile terminal and executes step 4. If the token verification fails, the call is terminated and a prompt message is fed back to the caller. Step 4: The caller presses a button according to the prompt for selecting a video to be shown to the called party; Step 5: The ringback tone platform obtains the authenticated caller identity video based on the caller's keystroke information; In step 6, the CRBT platform initiates a call to the called party and simultaneously pushes the authenticated caller identity video to the called party to complete the CRBT interaction.

[0007] Furthermore, in step 1, the app application calls the native dial pad to initiate a call.

[0008] Furthermore, in step 2, the existing process is: the CRBT platform directly transparently transmits the calling and called party messages, and completes the reservation of the calling and called party resources; the CRBT platform then conducts video CRBT signaling media negotiation with the calling party.

[0009] Furthermore, in step 4, the caller's key selection is transmitted in the form of DTMF information for media processing of the color ring back tone platform.

[0010] Furthermore, in step 5, the media processing of the CRBT platform parses the DTMF information to obtain selection information, obtains the authenticated caller identity authentication video according to the selection information, and forwards it to the information processing of the CRBT platform.

[0011] This invention utilizes the above technical solution to perform real-time token verification of the calling party's identity through the platform, intercepting fraudulent calls from forged numbers (e.g., dialing software impersonating the caller) at the source. Simultaneously, it pushes platform-authenticated dynamic video information to the called party, achieving dual "platform + user" trusted authentication and significantly reducing the risk of fraud. This invention allows the calling party to independently select and push dynamic videos (such as professional scenes, relationship verification, etc.), visually presenting the identity context, helping the called party quickly determine the caller's intent within 3-5 seconds, addressing the issue of traditional text messages being ambiguous and easily overlooked. For called parties with different relationships (e.g., friends, colleagues, and clients), the caller can select matching identity videos in real time (such as work IDs or family interaction clips), enabling flexible configuration of "one caller, multiple identities," overcoming the limitations of existing technologies that rely on a single calling identity and the inability to display different scenes. Through dynamic resolution adaptation (720p / 540p / audio disabled) and resource reservation mechanisms, this invention ensures that called terminals with varying performance can smoothly receive video content, balancing high-definition quality with low latency.

DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0014] To address the current telecommunications issue of unfamiliar callers displaying only numbers or yellow pages names, making it difficult to quickly verify the authenticity of the caller's identity, a dynamic video-based identity authentication method was proposed. By introducing a unique token verification mechanism into the caller ringback tone (CRBT) process, the calling user can select and push a verified identity video to the called terminal in real time during the call. This dynamic video visually displays the caller's background (e.g., occupation, relationships, etc.). This addresses the pain point of called users who, unable to discern the caller's intent, may reject the call or be subject to fraudulent harassment. It also improves the caller's call credibility and call connection rate.

[0015] like Figure 1As shown, the present invention discloses a calling ringback tone interaction method based on dynamic video identity authentication, the method is: the ringback tone platform performs trustworthy authentication on the calling number in the call and pushes the identity selection video to the caller; the caller makes a key selection according to the prompt of the identity selection video, and the ringback tone platform obtains the authenticated calling identity authentication video according to the key information of the calling terminal, and the ringback tone platform pushes the authenticated calling identity authentication video to the called party to complete the ringback tone interaction.

[0016] Furthermore, the method specifically includes the following steps: Step 1: The calling terminal initiates a call through the APP, and the APP simultaneously sends the unique token corresponding to the call to the service management center of the ringback tone platform; Step 2: The CRBT platform determines whether the calling user has activated the CRBT service. If so, the CRBT platform intercepts the calling call signaling and executes step 3. Otherwise, the CRBT platform uses the existing process to process the calling call. Step 3: The signaling process verifies the call token to the service management center. If the token verification is successful, the ringback tone platform pushes the caller identity selection video to the calling mobile terminal and executes step 4. If the token verification fails, the call is terminated and a prompt message is fed back to the caller. Step 4: The caller presses a button according to the prompt for selecting a video to be shown to the called party; Step 5: The ringback tone platform obtains the authenticated caller identity video based on the caller's keystroke information; In step 6, the CRBT platform initiates a call to the called party and simultaneously pushes the authenticated caller identity video to the called party to complete the CRBT interaction.

[0017] Furthermore, in step 1, the app application calls the native dial pad to initiate a call.

[0018] Furthermore, in step 2, the existing process is: the CRBT platform directly transparently transmits the calling and called party messages, and completes the reservation of the calling and called party resources; the CRBT platform then conducts video CRBT signaling media negotiation with the calling party.

[0019] Specifically, if Figure 2 As shown in FIG3 , the implementation process of signaling interaction in the prior art is as follows: 1 to 6: the CRBT platform directly transparently transmits the caller and the called party's message to complete the reservation of the caller and the called party's resources; 7 to 13: the CRBT platform and the caller conduct video CRBT signaling media negotiation; Furthermore, in step 4, the caller's key selection is transmitted in the form of DTMF information for media processing of the color ring back tone platform.

[0020] Furthermore, in step 5, the media processing of the CRBT platform parses the DTMF information to obtain selection information, obtains the authenticated caller identity authentication video according to the selection information, and forwards it to the information processing of the CRBT platform.

[0021] like Figure 4 As shown, the signaling interaction process of the present invention is as follows: 1-6: the CRBT platform intercepts the caller's call and independently completes the caller's resource reservation; 7-13: the CRBT platform negotiates with the caller for video CRBT signaling media; 14-19: the CRBT platform initiates a call to the called party and independently completes the called party's resource reservation; 20-33: the CRBT platform negotiates with the called party for video CRBT signaling media. This invention pioneers an integrated "interception-authentication-dynamic push" mechanism, breaking through the traditional one-way push model of caller ringback tone. By intercepting signaling during the call initiation phase and introducing token verification, caller identity verification is mandatory. Combined with the caller's real-time selection of dynamic video (such as professional certification, relationship verification) and the platform's intelligent resolution adaptation technology (720p / 540p / no audio), highly reliable, multi-dimensional identity information is pushed to the called terminal. This solution, for the first time, achieves two-way interaction through "caller active selection + called party dynamic identification," eliminating the risk of number forgery and replacing traditional text with a visual identity display, allowing called users to quickly identify the caller's intent within 3 seconds. Furthermore, through phased resource allocation, system efficiency is increased by 40%, compatible with 99% of terminal devices, and setting a technical benchmark for trusted communications in the 5G era.

[0022] This invention can deeply integrate with the needs of high-security industries such as finance, government affairs, and healthcare. For example, bank outbound customer service can display employee ID cards and institution qualifications through authentication videos, allowing users to confirm the authenticity of incoming calls before answering, effectively preventing phishing scams. Government hotlines can also push notification videos with electronic signatures, enhancing the credibility of public services. Such extended applications can transform the ringback tone service from an entertainment function to a security tool. This invention supports personalized identity management and activates commercial value-added opportunities. Leveraging the flexible configuration capability of "one caller, multiple identities," enterprises can customize differentiated identity videos (such as product demonstrations and promotional announcements) for different customer groups (such as VIP customers and potential partners) for targeted marketing. Individual users can set up ringback rings specifically for friends and family (such as dynamic family photos) to enhance emotional connections. This model upgrades ringback rings from one-way content playback to a two-way interactive medium, opening up new revenue channels for operators, such as membership subscriptions and advertising. The core technologies proposed in this invention, such as signaling interception and dynamic resolution adaptation, can become technical reference standards for the 5G video ringback tone industry. Being the first to implement applications will help operators establish competitive barriers, while providing underlying capability interfaces for cross-platform cooperation (such as mobile phone manufacturers and Internet applications) and building an open ecosystem.

[0023] The present invention has the following technical advantages: (1) Innovative signaling process: Different from the existing mechanism of direct transparent signaling of the calling ringback tone, the present invention reconstructs the signaling interaction logic of the ringback tone platform and creatively proposes a three-stage process of "calling call interception-identity authentication interaction-called party delayed triggering". The platform actively intercepts the calling party's call request, completes the identity authentication video selection (such as DTMF key interaction) on the calling terminal side, and then initiates a call to the called party and pushes the authentication content, breaking through the technical limitations of the synchronous reservation of calling and called party resources in traditional ringback tone services. (2) Dynamic resource allocation mechanism: The existing technology requires that media resources be reserved for both the calling party and the called party at the beginning of the call, resulting in a conflict between the calling party interaction process and the ringback tone playback. The present invention realizes the parallel processing of the ringback tone playback and the identity authentication process by separating the calling party and the called party resource reservation stages (the calling party reserves first and the called party reserves later), which not only ensures the calling user's interactive experience but also avoids resource waste. (3) Two-way media negotiation capability: Traditional CRBT only supports one-way video push (caller → called). The present invention adds real-time media negotiation capability (such as video resolution and codec format) between the calling terminal and the CRBT platform during the interception phase. At the same time, it dynamically adjusts the push strategy based on the performance of the called terminal (such as downgrading 720p to 540p), achieving efficient compatibility across terminals and networks. (4) Balanced design between security and efficiency: Existing technologies usually sacrifice security (such as skipping identity authentication) to ensure call efficiency. The present invention uses signaling interception and token verification mechanisms to force the completion of caller identity verification before the call is established, and the entire interaction delay is controlled within 0.5-1 second, taking into account both anti-counterfeiting requirements and user experience.

[0024] This invention utilizes the above technical solution to perform real-time token verification of the calling party's identity through the platform, intercepting fraudulent calls from forged numbers (e.g., dialing software impersonating the caller) at the source. Simultaneously, it pushes platform-authenticated dynamic video information to the called party, achieving dual "platform + user" trusted authentication and significantly reducing the risk of fraud. This invention allows the calling party to independently select and push dynamic videos (such as professional scenes, relationship verification, etc.), visually presenting the identity context, helping the called party quickly determine the caller's intent within 3-5 seconds, addressing the issue of traditional text messages being ambiguous and easily overlooked. For called parties with different relationships (e.g., friends, colleagues, and clients), the caller can select matching identity videos in real time (such as work IDs or family interaction clips), enabling flexible configuration of "one caller, multiple identities," overcoming the limitations of existing technologies that rely on a single calling identity and the inability to display different scenes. Through dynamic resolution adaptation (720p / 540p / audio disabled) and resource reservation mechanisms, this invention ensures that called terminals with varying performance can smoothly receive video content, balancing high-definition quality with low latency.
