Abstract
Description
Technical Field
[0001] The present invention relates to the field of wireless communication technology, and in particular to a caller ID display system and method based on a digital business card ecosystem. Background Art
[0002] Based on the current two-way distrustful call environment, most groups turn to Internet social networking, such as OTT application WeChat. Digital business card applications based on the WeChat ecosystem can quickly reveal one's identity in WeChat, such as All-in-One Business Card, Business Card Delivery, and Super Business Card. WeChat calls require friends to make calls, and the first contact phone communication is still a rigid demand.
[0003] Existing caller ID solutions are generally divided into three types: one is participated by operators, based on signaling monitoring, collecting the call signaling initiated by the calling side and then sending a flash message to the called party to inform the identity; the other is participated by mobile terminal manufacturers, binding the phone number with the label name and building a number library. After the terminal receives the call, it grabs the label name corresponding to the caller number in the number library for display; the third is participated by Internet companies, collecting user identity data through APP, and displaying the caller's identity through the implanted SDK when the user calls.
[0004] Patent CN113992794B discloses a method for displaying incoming call information, a mobile terminal and a computer storage medium, and provides a method for determining incoming call information, which is applied to a mobile terminal. In this way, when receiving an order logistics delivery call, the user can be efficiently prompted with specific information related to the order, so that the user can quickly understand the information of the delivered items. Patent application CN116866473A discloses an identity display method, terminal and server based on trusted communication. The calling terminal determines the calling identity of the calling user through the selection instruction of the calling user and uploads the communication token to the message server. The message server verifies the authority credentials corresponding to the communication token and the status information of the calling user. If the verification is successful, the calling terminal dials the called terminal using the call identity and calls the interface for sending flash messages, so that the message server verifies the call serial number of the communication token and determines whether the calling terminal monitors the ringing of the called terminal, and then sends a flash message or trusted information containing the calling user's call identity to the called terminal, so that the called terminal can verify the signature value of the communication token using the identity credentials of the calling user, and then display the calling identity of the calling user. The called user can confirm the real identity of the calling user in a timely and accurate manner. Patent application CN105744490A discloses a method, device and system for implementing a color printing service, by adding a ringing message carrying color printing content to the call response message returned by the called terminal and sending the call response message to the S-CSCF to which the called terminal belongs, so that the S-CSCF sends the call response message to the calling terminal to send the corresponding color printing content to the calling terminal or the S-CSCF sends the call response message to the calling terminal to send the color printing content carried therein to the calling terminal. The color printing service can be sent with low latency by directly carrying the color printing content in the call-related signaling.
[0005] In summary, the existing problems of the current technologies are: 1) Most of them are for corporate landline numbers, and mobile phone numbers are less covered; 2) The displayed content only includes the company name, and the individual caller information is not covered; 3) It is only for the calling side, and there is no caller ID that can be selected by the called side; 4) WeChat digital business card applications do not have the caller ID function in communication scenarios; 5) It relies on the built-in SDK of the APP for display, the threshold for app download is high, user coverage is insufficient, and terminal permission control must be opened. Summary of the invention
[0006] The purpose of the present invention is to provide a more convenient caller ID display system and method based on the digital business card ecosystem.
[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0019] Business card database module: used to create a digital business card for each user based on the relevant identity information that has passed the review and authentication, and store it in the business card database according to the fields;
[0020] Flash message template library module: used to generate flash message templates for each user based on relevant fields in the business card database.
[0021] Furthermore, the audit and authentication processing operations performed by the information authentication module include real-name authentication, address matching, and industrial and commercial yellow pages database matching.
[0022] Furthermore, there are two sets of flash message templates, namely a first template and a second template, and the first template and the second template are displayed accordingly based on the communication display switch policy set by the user.
[0023] Furthermore, the communication triggering layer includes:
[0024] Signaling monitoring module: used to obtain the existence of calling, ringing, and hanging up signals of the user's bound mobile phone number through signaling monitoring;
[0025] Strategy control module: used to retrieve the flash message template corresponding to the user and load it into the sequence to be sent based on the communication display switch strategy set by the user;
[0026] Communication trigger module: used to capture the flash message template in the sequence to be sent, and display the flash message template to the user through the flash message channel.
[0027] Furthermore, the logic processing method of the policy control module includes:
[0028] The calling side chooses to display to the called side, and the called side chooses to receive the communication display, and displays the first template in the flash message template to the called side;
[0029] The calling side chooses to display to the called side, and the called side chooses not to receive the communication display, and the second template in the flash message template is displayed to the called side;
[0030] The calling party chooses to display the message to the called party. If the called party is not a user of a digital business card, the second template in the flash message template is displayed to the called party.
[0031] The calling side chooses not to display the message to the called side, and the called side chooses to receive the communication display, and the first template in the flash message template is displayed to the called side;
[0032] The calling party chooses not to send a message to the called party, and the called party chooses not to receive the communication display. The called party does not display the flash message template;
[0033] The calling party is not a business card user, and the called party chooses not to receive communication display, so the flash message template is not displayed on the called party.
[0034] Furthermore, the communication trigger layer also includes a message trigger module, which is used to trigger a short message containing a short link to the called side or the calling side after the user hangs up, so that the user can click to view the flash message template.
[0035] The present invention also provides a display method of the caller ID display system based on the digital business card ecosystem described above, comprising the following steps:
[0036] The signaling monitoring module detects that the calling party's bound mobile phone number has a call signaling signaling, and the called party's bound mobile phone number has a ringing signaling signaling;
[0037] The policy control module matches the calling side and the called side to set the communication display switch policy. If the matching result shows that the flash message template does not need to be displayed to the called side, it will not be displayed. If the matching result shows that the flash message template needs to be displayed to the called side, the flash message template of the calling side is retrieved from the flash message template library, loaded into the sequence to be sent, and the flash message template in the sequence to be sent is displayed to the called side according to the communication trigger module.
[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0063] Template 2:
[0064] Name: XXXX
[0065] Company: XXXXXXXXXX
[0066] Department: XXXXXXXXXXX
[0067] Position:XXX
[0068] Mobile phone number: XXXX.
[0069] Communication trigger layer 3: When the user's communication behavior is obtained through signaling monitoring, the policy control module is responsible for matching the user's current communication policy. If the policy is met, the service trigger module is called and sent to the mobile phone number for display through the flash message channel.
[0070] (1) Signaling monitoring module 31: detects in real time whether there are any calling, ringing, or hanging up signals in the mobile phone number bound to the user, and then performs corresponding processing.
[0071] (2) Policy control module 32: The calling party can choose to display or not display the ID to the other party, and the called party can choose to receive or not receive the ID of the incoming call.
[0072] The logical processing method is: the calling party chooses to display it to the other party, and the called party chooses to receive the caller ID, and finally displays template 1;
[0073] The calling party chooses to display the caller ID to the other party, and the called party chooses not to receive the caller ID. Finally, template 2 is displayed.
[0074] The calling party chooses to display the card to the other party. The called party is not a business card user, and finally displays Template 2.
[0075] The calling party chooses to display the call to the other party, and the called party chooses to receive the caller ID. Finally, template 1 is displayed.
[0076] The calling party chooses not to display the caller ID, and the called party chooses not to receive the caller ID, and finally the caller ID is not displayed.
[0077] The calling party is not a business card user (no data), and the called party chooses not to receive caller ID, so it is not displayed in the end.
[0078] (3) Communication trigger module 33: The service uses flash message mode to retrieve the corresponding template content from the flash message template library module 23 and sends it to the called mobile phone user for display.
[0079] (4) Communication trigger module 34: After the user hangs up, a short message containing a short link is triggered to the called party or the calling party, so that the user can click to view the flash message template.
[0080] Based on the above-mentioned caller ID display system, the caller ID display method includes the following steps:
[0081] Step 1, user input information: the user fills in relevant information when registering a digital business card, and the information collection module 11 collects the relevant identity information of the user during registration, with each phone number as a unique identifier. The data includes the user's name, phone number, company, department, position, address, etc.
[0082] Step 2, information verification: user-related data is verified through the information authentication module 21, including real-name authentication, address matching, industrial and commercial yellow pages database matching, etc. The relevant data is obtained through the operator's CRM library, industrial and commercial yellow pages library, and base station positioning data.
[0083] Step 3: Generate digital business card: Generate digital business card after verification and store relevant data fields into business card database.
[0084] Step 4: Generate flash message templates: Generate 2 sets of flash message display templates for each user based on the relevant fields in the user's business card database.
[0085] Step 5: User edits policy: The user edits the sending and answering policy through the client, including turning on / off the caller ID function and choosing to display / not display to the other party; the policy editing module 13 synchronizes the user policy to the policy control module 32.
[0086] Step 6: User business card interaction: Users send digital business cards to each other and save them in the Internet scenario.
[0087] Step 7: Signaling monitoring: When a user calls another user, the signaling monitoring module 31 collects the calling user's call signaling and the called user's ringing signaling, and notifies the policy control module 32 to match the current policies of the two numbers.
[0088] Step 8: Sending strategy matching: The strategy control module 32 calls the flash message template corresponding to the calling and called users and loads it into the sequence to be sent according to the user strategy defined by the calling and called users.
[0089] Step 9: The communication trigger module captures the flash message template of the sequence to be sent in the strategy control module 32, and sends it to the called user through the flash message channel.
[0090] Step 10: The called user receives the business card information content preset by the caller.
[0091] Furthermore, after hanging up, the user can trigger a short message containing a short link to the caller or the outgoing caller, which the other party can click to jump to the business card application for detailed information.
[0092] Based on the above system and method, practical applications are carried out, such as Figure 2 As shown, the specific steps are:
[0093] 1. User 1 fills in relevant information when registering a digital business card. The information collection module 11 collects relevant identity information when the user registers, and each phone number is used as a unique identifier.
