Description

Technical Field

[0001] The present invention relates to the technical field of audio and video communication, and specifically provides a method for optimizing the quality of audio and video communication based on the VOLTE network. Background Art

[0002] VOLTE stands for Voice over Long-Term Evolution, which means a high-speed wireless communication standard for mobile phones and data terminals. It is based on the IP Multimedia Subsystem (IMS) network and uses configuration files (defined by the GSM Association in PRD IR.92) specifically designed for the control plane and the media plane of voice services on LTE. This enables voice services (control and media planes) to be transmitted as data streams in the LTE data bearer network, eliminating the need to maintain and rely on traditional circuit-switched voice networks. The voice and data capacity of VoLTE is more than three times that of 3G UMTS and more than six times that of 2G GSM. Since the packet header of VoLTE is smaller than that of unoptimized VoIP / LTE, it also makes more efficient use of bandwidth.

[0003] The most direct experience that VoLTE technology brings to 4G users is shorter connection waiting time and higher-quality, more natural voice and video call effects. VoLTE is fundamentally different from 2G and 3G voice calls. VoLTE is an end-to-end voice solution under full IP conditions based on the 4G network. Compared with 2G and 3G voice calls, the voice quality of VoLTE can be improved by about 40% because it uses high-resolution codec technology.

[0004] Currently, VoLTE calls mainly focus on voice calls. When video calls are required, third-party applications and third-party business system platforms, such as third-party application platforms like WeChat and QQ, are used. It is impossible to achieve mutual video calls between operator users without using a third-party platform, that is, it is impossible to achieve mutual video communication between customers of telecom operators, customers of China Unicom operators, and customers of China Mobile operators. Therefore, there is an urgent need for a method that can achieve mutual video communication between operator users. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for optimizing the quality of audio and video communication based on the VOLTE network, which can achieve mutual audio and video communication between customers of telecom operators, customers of China Unicom operators, and customers of China Mobile operators, and can also achieve mutual audio and video communication between operator customers and third-party applications. It has low cost and is very convenient to use.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0068] Embodiment 1

[0069] To solve the above problems, the present invention provides a technical solution: a method for optimizing the quality of audio and video communication based on the VOLTE network, as Figure 1 shown, including the following steps:

[0070] Step S1: Establish a video communication transmission channel between the operator user and the converged communication host;

[0071] The operator user docks with the VoLTE access module and the routing management through the Unicom IMS domain, establishes a dedicated bearer in the basic VoLTE call process of the VoLTE access module, and then conducts audio and video data transmission with the converged communication host through the VoLTE access module, the routing management, and the media service module. The converged communication host transmits the specified audio and video data, and sends the request to the VoLTE access module and the routing management through the signaling service module, and then transmits it to the specified operator user through the Unicom IMS domain;

[0072] Among them, the specific processes of the VoLTE access module include: Netloc location reporting and area code completion (in the scenario of a roaming user calling a local PSTN user), calling or called service anchoring (for the scenario of a CS access domain calling a VoLTE user), called access domain selection (T-ADS), establishment of dedicated bearers on the calling and called sides (voice and video retransmission), eSRVCC-related processes (such as handover), interoperability with VoWiFi, and ICS.

[0073] The present invention innovatively establishes a dedicated bearer in the basic VoLTE call process. The VoLTE user can establish an IMS dedicated bearer (voice / video bearer, QCI = 1 / 2) for the user through the visited EPS network to achieve audio and video communication, as Figure 2 shown.

[0074] In VoLTE, a dedicated IMS APN is required, and different bearers are selected according to its needs:

[0075] The SIP signaling message always uses the bearer with QCI = 5;

[0076] The voice media stream uses a dedicated bearer with QCI = 1;

[0077] The video media stream uses a dedicated bearer with QCI = 2;

[0078] Other IMS services, such as instant messaging, can use a bearer with QCI = 9;

[0079] The Internet service uses other APNs;

[0080] Figure 3A Schematic diagram for triggering the establishment of a dedicated bearer on the calling side; Figure 3B Schematic diagram for triggering the establishment of a dedicated bearer on the called side; Figure 3C Schematic diagram for call establishment; Figure 3D Schematic diagram for call hangup; Figures 3A - 3D It is the overall process for realizing audio and video communication through the establishment of the entire dedicated bearer.

[0081] The routing management routing principle is as follows: VoLTE users attach to LTE. If the called party is a VoLTE user, the call is routed to the called party's home IMS domain, and the called party's home IMS performs called domain selection, and subsequent routing is carried out according to the domain selection result.

[0082] Step S2: Establish a video communication transmission channel between the third-party application and the converged communication host;

[0083] After the third-party application is docked with the third-party service system platform, the audio and video data is transmitted to the webrtc service module through the third-party service system platform, and then transmitted to the converged communication host by the webrtc service module. The converged communication host transmits the specified audio and video data to the specified third-party application through the webrtc service module and the third-party service system platform;

[0084] Step S3: Perform converged communication through the converged communication host to complete the audio and video communication between operator users and specified operator users, the audio and video communication between third-party applications and specified third-party applications, the audio and video communication between third-party applications and specified operator users, and the audio and video communication between operator users and specified third-party applications.

[0085] 1) The method for audio and video communication between operator users and specified operator users, as Figure 4 shown;

[0086] It includes the following steps:

[0087] Step S11: The operator user docks with the VoLTE access module and routing management through the Unicom IMS domain, sends an audio and video data access request. The request data is transmitted to the media service module and then to the converged communication host. The converged communication host transmits the request to the VoLTE access module and routing management through the signaling service module, and then transmits it to the specified operator user through the Unicom IMS domain;

[0088] Step S12: After the specified operator user accepts the audio and video data request, both the operator user and the specified operator user send the audio and video data to the VoLTE access module and routing management through the Unicom IMS domain. Then, it is transmitted to the converged communication host through the media service module. After performing converged information, the audio and video data of the operator user is transmitted to the specified operator user through the signaling service module, VoLTE access module and routing management, and Unicom IMS domain. The audio and video data of the specified operator user is transmitted to the operator user through the signaling service module, VoLTE access module and routing management, and Unicom IMS domain, completing the audio and video communication.

[0089] 2) The method for audio and video communication between a third-party application and a specified third-party application is as Figure 5 shown;

[0090] including the following steps:

[0091] Step S21: After the third-party application docks with the third-party service system platform, it sends an audio and video data access request. The request is transmitted to the webrtc service module and the converged communication host through the third-party service system platform. Then, the converged communication host transmits it to the third-party service system platform through the webrtc service module, and then the third-party service system platform transmits it to the specified third-party application;

[0092] Step S22: After the specified third-party application accepts the audio and video data access request, both the third-party application and the specified third-party application send the audio and video data to the third-party service system platform, webrtc service module, and converged communication host. The converged communication host sends the audio and video data to the media service module, signaling service module, and recording service module for converged communication. Then, the audio and video data of the third-party application is transmitted to the specified third-party application through the webrtc service module and the third-party service system platform. The audio and video data of the specified third-party application is transmitted to the third-party application through the webrtc service module and the third-party service system platform, completing the audio and video communication.

[0093] 3) The method for audio and video communication between a third-party application and a specified operator user is as Figure 6 shown;

[0094] including the following steps:

[0095] In step S31, after the third-party application is docked with the third-party business system platform, it sends an audio / video data access request. The request is transmitted through the third-party business system platform to the WebRTC service module and the converged communication host, and then the converged communication host transmits the request to the VoLTE access module and the routing management through the signaling service module, and then transmits it to the specified operator user through the Unicom IMS domain.

[0096] In step S32, after the specified operator user accepts the audio / video data request, the specified operator user sends the audio / video data to the VoLTE access module and the routing management through the Unicom IMS domain, and then transmits it to the converged communication host through the media service module. At the same time, the third-party application sends the audio / video data to the third-party business system platform, the WebRTC service module, and the converged communication host. The converged communication host performs converged communication, transmits the audio / video data of the specified operator user to the third-party application through the WebRTC service module and the third-party business system platform, and transmits the audio / video data of the third-party application to the specified operator user through the signaling service module, the VoLTE access module and the routing management, and the Unicom IMS domain to complete the audio / video communication.

[0097] 4) The method for audio / video communication between an operator user and a specified third-party application is as Figure 7 shown;

[0098] including the following steps:

[0099] In step S41, the operator user docks with the VoLTE access module and the routing management through the Unicom IMS domain, sends an audio / video data access request, and the request data is transmitted to the converged communication host through the media service module. The converged communication host is transmitted to the third-party business system platform through the WebRTC service module, and then transmitted to the specified third-party application by the third-party business system platform.

[0100] In step S42, after the specified third-party application accepts the audio / video data request, the specified third-party application sends the audio / video data to the third-party business system platform, the WebRTC service module, and the converged communication host. At the same time, the operator user sends the audio / video data to the VoLTE access module and the routing management through the Unicom IMS domain, and then transmits it to the converged communication host through the media service module. After performing the fusion information, the audio / video data of the third-party application is transmitted to the operator user through the signaling service module, the VoLTE access module and the routing management, and the Unicom IMS domain. At the same time, the audio / video data of the operator user is transmitted to the third-party application through the WebRTC service module and the third-party business system platform to complete the audio / video communication.

[0101] When the integrated communication host of the present invention performs integrated information, it transmits audio and video data to the recording service module, and the recording service module realizes recording and storage of the session link established for integrated communication, which is convenient for event backtracking.

[0102] When the integrated communication host of the present invention performs integrated information, the dispatcher completes the docking with the integrated communication host through the integrated dispatching console and controls the integrated communication host according to the feedback information.

[0103] The integrated communication of the present invention can be docked with the VoLTE access gateway service and the Unicom IMS core network, and then it can be realized that operator users can make audio and video calls without installing a third-party application APP. The integrated communication provides a secondary open interface for third-party service platforms to use.
