[0050] With the rapid development of communication technology, VoLTE (Voice over LTE) technology has become the mainstream technology in the current high-definition voice communication and video communication field. VoLTE technology realizes clear and smooth transmission of voice and video by using the high bandwidth and low delay characteristics of LTE network, greatly improving the user's communication experience. In the application scenario of the embodiments of the present application, the demand for high-definition video communication services of users in the market is increasing, and users expect to enjoy high-quality and diversified communication services in various communication scenarios.

[0051] However, in the key communication field of call center, there is a problem that most call centers do not have video communication capability due to the relatively early construction time of their system architecture and hardware devices. Call centers still mainly rely on traditional voice connection mode and cannot meet the urgent demand of users for high-definition video communication services. Therefore, how to make call centers adapt to the development of VoLTE technology and realize high-definition video communication capability has become an important issue to be solved at present.

[0052] In order to solve the deficiency of call center in high-definition video communication capability, the existing technology mainly adopts two kinds of architecture for improvement. The first architecture is to access PSTN (Public Switched Telephone Network) through E1, but this way cannot carry the demand of VoLTE video communication due to the limitation of link design. If VoLTE video communication is to be realized, large-scale system modification is needed, including replacing the whole set of system equipment and changing the access line, which will bring high cost investment and long time period, which is not conducive to the rapid upgrading and transformation of call center.

[0053] Another architecture is to adopt the SIP (Session Initiation Protocol) relay access mode. Compared with the first architecture, the SIP relay link can theoretically carry the VoLTE video communication. However, in actual application, part of the queue machines, business systems and SIP phones used by the agents do not support the video communication function, which limits the wide application of the VoLTE video communication in the call center. Therefore, if the VoLTE video communication support is to be realized, the whole system must be comprehensively upgraded, which will also bring high cost and long time period, and is not conducive to the rapid development of the call center and the satisfaction of user demand.

[0054] In summary, the prior art has obvious deficiencies and limitations in solving the high-definition video communication capability of the call center, and an efficient, economical and feasible solution is needed to promote the upgrade and transformation of the call center. Therefore, the present application proposes a media auxiliary stream method based on VoLTE call, aiming to solve the above problems and realize the rapid and low-cost improvement of the high-definition video communication capability of the call center.

[0055] In the embodiment of the present application, the media auxiliary stream method based on VoLTE call is applied to an application server of an operator, and a media sorting service module is arranged in the application server. The method comprises the following steps:

[0056] Obtaining a first call request sent by a user terminal.

[0057] In the embodiment of the present application, the three major domestic telecom operators adopt IMS technology by default on newly laid fixed telephone lines, and upgrade the traditional PSTN line. The telephone line supported by the IMS system can carry the SIP protocol and realize the transmission of voice and video. If a user wants to enjoy the high-definition call service by using a terminal such as a smart phone supporting VoLTE function, he needs to sign a corresponding service agreement with the operator, and the service will not consume the user's mobile data flow.

[0058] It can be understood that in the embodiment of the present application, IMS (IP Multimedia Subsystem) is an IP multimedia subsystem, which is a multimedia service form based on IP network, aiming to provide users with multimedia services such as voice, video and message, and can support the fusion of multiple access networks (such as cellular network, Wi-Fi and fixed network), and provide a highly flexible and extensible multimedia service platform.

[0059] In this embodiment, IMS can be used to refer to an intranet management system. The intranet management system can be a hierarchical database and information management system that assists in transaction processing, a database-driven secure integrated platform that supports high-performance online transactions and data processing, has high security, flexibility and scalability, and is suitable for business workflow within an enterprise unit.

[0060] Query the service data corresponding to the first call request, and configure corresponding service identification data for the first call request based on the service data.

[0061] In the embodiments of the present application, the service identification data can be configured in the HSS (Home Subscriber Server) / UDM (Unified Data Management), and the service identification data after configuration will be stored in the user subscription information. When the user initiates a call, the S-CSCF (Service Call Session Control Function) network element, as the core component of the IMS (IP Multimedia Subsystem) architecture, will be responsible for processing the call request and interacting with the HSS / UDM.

[0062] In the embodiments of the present application, the HSS can be an important component of the control layer in the IP multimedia subsystem (IMS), and serves as a core role for storing and managing user-related information. The HSS is responsible for storing and managing user-related information, including user configuration files, supporting user authentication and authorization, service customization and triggering, location management and mobility support, and other functions. In the call process, the S-CSCF network element loads service data from the HSS, triggers the service according to the IFC in the service identification data, thereby ensuring correct routing and processing of the call.

[0063] In the embodiments of the present application, the UDM is a unified user data management product for future 5G networks, and complies with the 3GPP standard. It can achieve management of 5G user authentication data, access authentication of 5G users, and also provides mobility management, access authentication, service authorization and other basic network functions for traditional 2G / 3G network, EPS network and IMS network users.

[0064] It can be understood that the S-CSCF network element queries the HSS / UDM according to the user information in the call request to obtain the subscription information and service identification data of the user. The information determines the processing mode of the call and the type of the service provided. After the service data is loaded, the S-CSCF network element processes the call according to the data, such as routing selection, session control, media resource allocation, and the like. Meanwhile, the S-CSCF triggers the corresponding service logic according to the service identification data to ensure that the required service is provided for the user.

[0065] In the embodiment of the present application, the service identification data can refer to data indicating the type of the service subscribed by the user or the preferential policy. The service identification data is usually stored in the HSS / UDM as part of the user subscription information. In the call process, the S-CSCF network element triggers the corresponding service logic according to the service identification data to ensure that the required service is provided for the user.

[0066] In the embodiment of the present application, the S-CSCF (Service Call Session Control Function) is one of the core components of the IMS architecture, responsible for processing the call request and session control of the user. The S-CSCF network element realizes the functions of routing selection, session control, media resource allocation, and the like of the call through interaction with other network components. In the call process, the S-CSCF network element triggers the corresponding service logic according to the subscription information and service identification data of the user.

[0067] In the embodiment of the present application, the call process can refer to the whole process from the user initiating the call to the end of the call. In the call process, the call request of the user is sent to the S-CSCF network element for processing. The S-CSCF network element triggers the corresponding service logic according to the subscription information and service identification data of the user, and interacts with other network components to realize the functions of routing selection, session control, and the like of the call.

[0068] According to the service trigger request, a second call request is determined and sent.

[0069] According to the service trigger request processed based on the media parameter, a second call request is determined and sent.

[0070] In the embodiment of the present application, as shown in Figure 1 In the VoLTE (Voice over LTE) call scenario, when the user initiates the call, the application server receives the call request of the user. The request contains the identity information of the user, the called number, and possibly the call parameters. After receiving the call request, the application server queries the service database according to the information of the user to obtain the service identification data related to the user.

[0071] In the embodiments of the present application, after obtaining the service identification data, the application server can send a service trigger request to the media sorting service module according to the service identification data. The request contains the service identification data and possibly other related information, such as user ID, call request ID, etc.

[0072] The media sorting service module can be a functional module in the application server, which is used to process the media data according to the service identification data in the service trigger request. For example, it includes adjusting the encoding format, resolution, bit rate, etc. of the media data to meet the needs of specific services. If the user subscribes to a high-definition video call service, the media sorting service module will perform high-definition encoding processing on the media data.

[0073] In the embodiments of the present application, the media sorting service module can be a functional module in the application server, which is responsible for processing the media data according to the service identification data in the service trigger request. To ensure that the media data can be transmitted and processed according to the needs of specific services.

[0074] In the embodiments of the present application, the service trigger request can refer to the request sent by the application server to the media sorting service module according to the service identification data. It is used to trigger the media sorting service module to process the media data.

[0075] In the embodiments of the present application, as shown in Figure 2 , it also includes:

[0076] When the media sorting service module receives a first call request for obtaining a VoLTE video stream or a voice stream, a media renegotiation mechanism is started. The media renegotiation mechanism is used to dynamically adjust the media parameters according to the media and network compatibility factors of the corresponding device in the session description protocol.

[0077] On the basis of the above-mentioned embodiments, after the call is established, a third call request can be initiated through the agent auxiliary flow plug-in, the media renegotiation of the session is performed through the media sorting service module provided in the application server, the three-party session is fused, and the media is split, so that the audio stream of the session is still transmitted using the original link, and the video stream (media auxiliary stream) is transmitted to the agent auxiliary flow plug-in using an independent link.

[0078] On the basis of the above-mentioned embodiments, specifically, it also includes:

[0079] S200, obtaining a first call request sent by a user terminal.

[0080] S201, querying service data corresponding to the first call request, and configuring corresponding service identification data for the first call request based on the service data.

[0081] S202, sending a service trigger request to the media sorting service module according to the service identification data.

[0082] S203, determining and sending a second call request based on the service trigger request after media parameter processing.

[0083] S204, initiating a third call request based on the agent auxiliary flow plug-in after starting the media renegotiation mechanism.

[0084] In this embodiment, the purpose is to realize media splitting in a three-party call, in which the audio stream is transmitted through the original link, and the video stream (media auxiliary stream) is transmitted to the agent auxiliary flow plug-in through an independent link. The media sorting service module in the application server performs media renegotiation and three-party session fusion. The agent auxiliary flow plug-in can be a software component installed on the agent side, which allows the agent to initiate a third call request after the call is established. The plug-in can receive and process the video stream (media auxiliary stream) transmitted through the independent link, and provide additional video information for the agent.

[0085] In the embodiment of the present application, during the establishment of a three-party call, the media sorting service module initiates a media renegotiation process. This process involves communication with all participants to ensure that all parties are aware of and accept the new media transmission scheme. The result of media renegotiation will determine the specific transmission link and format of the audio stream and the video stream.

[0086] It can be understood that the media sorting service module is also responsible for the fusion of the three-party session. The media sorting service module synchronizes and integrates the media streams from different participants to ensure that all participants' information can be seen and heard simultaneously at the agent side. The audio stream remains the original link transmission, which means that in a three-party call, the audio information is still transmitted through the original communication network. The video stream (media auxiliary stream) is transmitted to the agent auxiliary flow plug-in through an independent link. The media sorting service module is responsible for separating the video stream from the original session and sending it to the agent auxiliary flow plug-in through an independent link for processing and display.

[0087] As can be seen, the above technical solution improves the flexibility and scalability of communication. Through media splitting and renegotiation, it can easily adapt to different communication scenarios and needs. The audio stream and the video stream are transmitted through different links respectively, avoiding resource competition and bandwidth waste. The agent can more clearly obtain the information of the participants, so as to make more accurate judgments and responses.

[0088] In the embodiments of the present application, the media renegotiation mechanism can be defined as a mechanism for dynamically adjusting media parameters, aiming to ensure the smooth progress of the session and the compatibility of the media stream. The media parameters are dynamically adjusted according to the media and network compatibility factors of the corresponding device in the session description protocol (SDP). The above-mentioned parameters can include encoding format, resolution, bandwidth requirement, etc.

[0089] Further, the session description protocol (SDP) is used to describe the media components and formats of the session in the multimedia session. The SDP contains information such as media support of the device and network conditions, which are important basis for the media renegotiation mechanism to adjust the parameters, i.e., media and network compatibility factors.

[0090] In practical applications, as shown in FIG. 1, for example, in a VoLTE video call scenario, two users (including user A and user B) use different devices and network environments. Figure 3

[0091] User A initiates a VoLTE video call request to user B. The media sorting service module receives the request and identifies that it is a call request for obtaining a VoLTE video stream. The media sorting service module starts the media renegotiation mechanism, which first obtains the device information and network conditions of user A and user B. The above-mentioned information is usually contained in the SDP. The device of user A supports high-definition video encoding (such as H.264), while the device of user B only supports lower resolution video encoding (such as VP8). The media renegotiation mechanism dynamically adjusts the media parameters according to the above-mentioned information, respectively, to ensure that user B can receive compatible video streams. In the above-mentioned case, the media renegotiation mechanism can select an encoding format supported by the device of user B, and reduce the video resolution to adapt to the network bandwidth of user B. After the adjustment of the media renegotiation mechanism, the VoLTE video call session between user A and user B is established. The media stream can include video and audio, and is transmitted according to the negotiated parameters, ensuring the smooth progress of the call.

[0092] Through the above example, it can be seen that the media renegotiation mechanism is important in the VoLTE video call. The media renegotiation mechanism can dynamically adjust the media parameters according to the media capabilities of the device and the network conditions, thereby ensuring the compatibility and stability of the session.

[0093] In the embodiments of the present application, the media sorting service module further includes the following steps during the processing of the first call request:

[0094] ​The media sorting service module performs media sorting processing on a first call request containing a VoLTE video stream and a voice stream, and sends the video stream and the voice stream after the media sorting processing to different receiving ends respectively.

[0095] In the embodiments of the present application, media sorting processing can be defined as a technology of separating and processing multiple media types (such as video and voice) in a call request. It is used to ensure that each media type can be correctly identified, processed, and sent to the corresponding receiving end, so as to improve the efficiency and quality of media transmission.

[0096] In actual application, it is assumed that in a VoLTE video call scenario, user A (located at a smart phone end) is making a video call with user B (located at a smart TV end), and user C (located at another smart phone end) wants to join only the voice call part.

[0097] Firstly, user A initiates a call request containing a VoLTE video stream and a voice stream, and the target is user B and user C. The media sorting service module receives the call request, and identifies that the call request of user A contains both a video stream and a voice stream. The media sorting service module separates the video stream and the voice stream according to the information in the call request. The video stream is marked to be sent to user B (the smart TV end), and it can be understood that the receiving end of user B has a larger screen and better video playing capability. The voice stream is marked to be sent to user B and user C at the same time, both of which need to participate in the voice call. The media sorting service module sends the separated video stream to the smart TV end of user B for video playing. At the same time, the media sorting service module sends the voice stream to the smart TV end of user B (if the smart TV supports voice output) and the smart phone end of user C. In this process, the media sorting service module also needs to process the synchronization of audio and video to ensure that user B and user C can experience smooth multimedia communication at the receiving end.

[0098] During the call, after the processing of the media sorting service module, the video call between user A and user B and the voice call between user A and user B and C can be carried out smoothly. User B can watch the video call picture at the smart TV end and hear the voice call content through the smart TV or connected sound equipment. User C only hears the voice call content at the smart phone end and does not participate in the video call part. It can be seen that the media sorting service module plays an important role in the VoLTE video call scenario. The media sorting service module can perform media sorting processing according to actual demand and send them to the corresponding receiving end, so as to meet various multimedia communication demands.

[0099] In actual application, for example, Figure 4 , 5As shown, for example, using a media auxiliary stream system to enable VoLTE video for a call center, Figure 4 For an incoming call scenario, step 1: a user initiates an incoming call request to the system; step 2: service triggering; step 3: continuous paging; step 4: paging to the corresponding network element; step 5: paging to the target call center; step 6: the agent answers the call, and a voice call is successfully established. Step 7: the agent initiates a media auxiliary stream request; step 8: the plug-in processes the media auxiliary stream request; step 9: the media auxiliary stream request is forwarded; step 10: media renegotiation is performed on the existing session; and step 11: the media renegotiation information is sent to the calling terminal.

[0100] Figure 5 For an outgoing call scenario, step 1: a customer service representative initiates a call; step 2: the call center makes an outgoing call; step 3: the call is connected to the calling S-CSCF; step 4: the service is triggered; step 5: continuous paging; step 6: the call is answered, and a call connection is established. Step 7: the customer service representative initiates a media auxiliary stream request; step 8: the plug-in processes the media auxiliary stream request; step 9: the media auxiliary stream request is forwarded; step 10: media renegotiation is initiated to the existing session; and step 11: the media renegotiation information is sent to the calling terminal. The media stream is consistent with the incoming call scenario.

[0101] In the embodiments of the present application, before sending the second call request, the following steps are included:

[0102] The second call request is prioritized, wherein the priority of the call request is determined according to the service type, user level, or network condition factors;

[0103] The second call request is sent according to the priority order.

[0104] In the embodiments of the present application, in a communication system, there are multiple call requests waiting for processing at the same time, which can come from different users, different service types, and can be affected by different network conditions. In order to improve the efficiency of the system in processing call requests and ensure that high-priority requests are processed first, it is necessary to prioritize these call requests.

[0105] In the embodiments of the present application, according to the determined priority factors, the system will sort the second call request to form a priority queue. The system can send the call request to the corresponding processing module or network device for processing in turn according to the order of the priority queue.
