Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to an automatic audio and video notification system and method based on an IMS network. Background Art

[0002] As the impact of customer operation and expansion on the business development of small and medium-sized merchants becomes increasingly important, pushing audio or video notifications to member users to achieve the purpose of customer retention and management has become the main means for small and medium-sized merchants to build and operate their private domains.

[0003] Considering the delivery rate of notifications, currently, customers mainly adopt two methods

[0004] Method 1: Manual dialing.

[0005] This method has problems such as low dialing efficiency, occupying a large amount of time of customers, and at the same time, customers cannot answer incoming calls during the notification period, and it is inconvenient to statistically analyze the notification effect afterwards.

[0006] Method 2: Entrusting a call center to make notifications.

[0007] Although it can solve the problems existing in manual dialing, it has problems such as high cost for renting call center lines, the outgoing call showing the call center number instead of the actual customer's number, which is not conducive to identity identification, and users cannot call back.

[0008] In addition, there are also some technologies for automatically initiating outgoing calls. For example, patent application CN116456030A discloses an intelligent outgoing call method based on an outgoing call gateway, including: receiving an outgoing call task of any outgoing call service system through the outgoing call gateway, and automatically allocating a customer service seat when the outgoing call gateway receives the outgoing call task; obtaining the seat information of the customer service seat allocated by the outgoing call gateway; and through the outgoing call gateway and according to the seat information of the allocated customer service seat, calling up the softphone corresponding to the target outgoing call relay service to use the softphone corresponding to the target outgoing call relay service to perform the outgoing call task. Although this method can solve the problem of dialing efficiency, there are still problems such as customers being unable to answer incoming calls during the notification period and the number display.

[0009] In summary, there is an urgent need for an audio and video notification method that can automatically and efficiently initiate notifications to target customers in batches, display the customer's own mobile phone number at the same time, and does not affect the normal calls of users, so as to promote the development and popularization of notification services. Summary of the Invention

[0010] The purpose of the present invention is to overcome the defects existing in the above-mentioned prior art and provide an automatic audio and video notification system and method based on an IMS network, which improves the notification efficiency, solves the problems that the outgoing call platform cannot display the customer's mobile phone number and customers cannot answer incoming calls during the notification period, and further improves the customer communication efficiency and business usage experience.

[0011] The object of the present invention can be achieved by the following technical solutions:

[0012] An automatic audio and video notification system based on the IMS network, comprising an IP multimedia subsystem, an intelligent notification platform and an operator IT subsystem. The IP multimedia subsystem is used to connect the intelligent notification platform and the operator IT subsystem and process various call signaling; the intelligent notification platform is used to receive configuration requests from notification subscribing customers, generate notification policies according to the configuration requests, and initiate notifications to member users regularly according to the notification policies; the operator IT subsystem is used to receive subscription requests from notification subscribing customers and save them as iFC subscription information.

[0013] Furthermore, the IP multimedia subsystem includes a home subscriber server, a call session control function network element and a session border controller. The home subscriber server is used to record the iFC subscription information of notification subscribing customers in the IP multimedia subsystem; the call session control function network element is used to process various call signaling in the IP multimedia subsystem; the session border controller is used to connect the terminals of member users and the intelligent notification platform to the IP multimedia subsystem.

[0014] Furthermore, the IP multimedia subsystem further includes a capabilities platform, and the capabilities platform is connected to the intelligent notification platform through a communication control interface.

[0015] Furthermore, the home subscriber server generates service trigger data according to the iFC subscription information of the notification subscribing customers and synchronizes the service trigger data to the call session control function network element.

[0016] Furthermore, the service trigger data includes a trigger condition and the application server address for processing services after triggering.

[0017] Furthermore, the intelligent notification platform includes a policy configuration module, a call control module and a report statistics module. The policy configuration module is used to set notification policies, the call control module is used to automatically initiate audio and video notifications to member users regularly according to the notification policies, and the report statistics module is used to automatically collect feedback from member users after the video notification ends.

[0018] Furthermore, the notification policies include multiple ones such as a notification time period, a notification interval, whether to enable an AI answering policy, whether it is a video notification, a notification member list and notification content.

[0019] Furthermore, the call control module includes an intelligent engine, and the intelligent engine is used to perform real-time speech recognition on the answering feedback of member users.

[0020] Further, the operator IT subsystem includes a service acceptance module and a user account module. The service acceptance module is used to receive the signing request of the notified subscription customer, and the user account module is used to save the iFC signing information of the notified subscription customer.

[0021] According to another aspect of the present invention, there is provided an automatic audio and video notification method based on an IMS network. By using the above-mentioned automatic audio and video notification system based on the IMS network for automatic audio and video notification, the method includes the following steps:

[0022] The intelligent notification platform starts a notification task according to the notification strategy preset by the notified subscription customer, selects the first number in the notified member list and prepares to initiate a notification;

[0023] The intelligent notification platform transmits call control information to the capability platform through a communication control interface. The call control information includes the outbound number used by the intelligent notification platform this time, the signed mobile phone number of the notified subscription customer, and the number of the member user to be notified;

[0024] The capability platform caches the received call control information, forms an index, and then feeds back that the call control information has been cached to the intelligent notification platform;

[0025] After receiving the feedback from the capability platform that the caching is completed, the intelligent notification platform makes an audio and video call from the outbound number used by the intelligent notification platform to the signed mobile phone number of the notified subscription customer. When the audio and video call enters the IP multimedia subsystem, the audio and video call is routed to the capability platform according to the iFC signing information of the called customer number;

[0026] After receiving the audio and video call, the capability platform checks whether the called customer number is a platform-signed number:

[0027] If the called customer number is not a platform-signed number, the capability platform rejects the current call request and notifies the intelligent notification platform. If the called customer number is a platform-signed number, the capability platform matches the index relationship of the call control information still within the validity period in the cache according to the main and called numbers of the received call:

[0028] If the matching is successful, the capability platform completes the call signaling negotiation with the member user number according to the call control information it matches, and pushes the notification content to the member user. If the matching fails, the capability platform rejects the current call request and notifies the intelligent notification platform;

[0029] The capability platform feeds back the result of this notification to the intelligent notification platform according to the answering situation of the member user, and completes this notification;

[0030] The intelligent notification platform determines whether the notifications to all member users have been completed:

[0031] If the notifications for all member users have been completed, an analysis report of this notification task is generated based on the connection status and feedback of the member users. If not all member users have been notified, a new round of notifications is initiated.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. In the present invention, the capability platform is deployed in the IP multimedia subsystem in the form of a service server. The intelligent notification platform initiates an audio-visual call to the subscribed mobile phone number of the notified customer using the outbound number. The call session control function network element sends the call to the capability platform according to the service trigger data. The capability platform completes the negotiation of signaling and media with the member user terminal according to the call control information provided by the intelligent notification platform, realizing the logic of the notification service. Thus, the problems that the outbound platform cannot display the customer's mobile phone number and the customer cannot answer the incoming call during the notification are solved simultaneously, further improving the customer communication efficiency and business usage experience.

[0034] 2. The intelligent notification platform constructed by the present invention includes a call control module and a report statistics module. The call control module includes an intelligent engine. According to the notification strategy preset by the notified customer, the call control module automatically initiates audio-visual notifications to member users at regular intervals. There is no need for users to manually dial. The content of the notification is pushed by the platform, which is safe and controllable. The intelligent engine performs real-time speech recognition on the response feedback of member users, and the report statistics module automatically records and analyzes user feedback and generates corresponding statistical reports, improving the notification efficiency of customers.
