Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the present invention, the words "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
Existing audio and video calls commonly adopt session initiation protocol (Session Initiation Protocol, SIP) or session description protocol (Session Description Protocal, SDP) protocols for call signaling control, including registration, session negotiation, session establishment, release, and other procedures. When the terminal initiates a call, whether the call is a video call or not is judged according to whether the contact header field in the calling initial INVITE message contains a video tag or whether the SDP carries a video media line or not. If the initial call is a video call, the audio call can be negotiated for the second time before the call, or any one of the two parties can be switched to the audio call in the call process. If the initial call is an audio call, the video call can be negotiated for the second time before the call, and the video call is updated in the call.
By way of example, FIG. 1 provides a diagram of an existing audio video service system, as shown in FIG. 1, comprising a user terminal 101, a signaling system 102, a media service system 103, a service terminal 104, an audio service system 105, and a video service system 106.
When an audio call is conducted, the user terminal 101, the signaling system 102, the media service system 103, the service terminal 104 and the audio service system 105 in the audio-video service system architecture assist in completing the related audio services.
When a video call is conducted, the user terminal 101, the signaling system 102, the media service system 103, the service terminal 104 and the video service system 106 in the architecture of the audio and video service system assist in completing related video services.
From the above, it can be seen that, due to the different audio/video processing logic in the industry application, the related business application needs to trigger different logic and select different program paths according to the call type to complete the whole interaction. The decision of the current call type is determined by the terminal and the communication system, the call type switching is controlled by the terminal and the communication system, the service system is more an application attached to the communication system, the service logic and the communication logic are in a separated state, and the service system is difficult to adapt when encountering an audio/video switching scene.
In view of this, the present invention provides a method for switching an audio call to a video call, in which when a user terminal requests to switch a call between a user terminal and a service terminal from an audio call to a video call, a video service system is requested to reserve system resources required for performing a video call between the user terminal and the service terminal. Therefore, the service terminal can use the reserved system resources to create the video media channel, so that the service terminal and the user terminal can carry out video call through the video media channel, and the smoothness of the process of switching the audio call into the video call is improved.
The embodiment of the invention provides an optimization method for switching an audio call into a video call, which can be applied to a device for switching the audio call into the video call. For example, the means for switching the audio call to the video call may be an architecture for an audio video service system. Optionally, the device for switching the audio call to the video call may also implement a function to be implemented by the device for switching the audio call to the video call by a Virtual Machine (VM) deployed on a physical machine.
An exemplary architecture diagram of an audio/video service system provided by an embodiment of the present invention is shown in fig. 2. The audio and video service system architecture may include: a user terminal 101, a signaling system 102, a media service system 103, a service terminal 104, an audio service system 105, a video service system 106 and an audio-video service continuity switching system 107.
The audio and video service continuity switching system 107 may include a signaling capture subsystem 1071 and a control inverse subsystem 1072, among other things.
The user terminal 101 establishes a connection with the signaling system 102 through signaling, and is used for interacting with a user, and transmitting a user operation instruction to the signaling system 102 through a signaling manner. The user terminal 101 may be a physical machine, for example: desktop computers, also known as desktops or desktops (desktops), cell phones, tablet computers, notebook computers, ultra-mobile personal computers (UMPC), netbooks, personal digital assistants (personal digital assistant, PDA), etc., may also be terminals used by users such as WeChat applets, etc., or may also be some third party applications.
The signaling system 102 establishes connection with the audio/video service continuity switching system 107 through signaling, and is responsible for signaling proxy and transmission functions such as user terminal registration, session and media negotiation, terminal release, and the like.
The media service system 103 is connected to the user terminal 101 and the service terminal 104, and exchanges and transmits media streams with the user terminal and the service terminal respectively through a Real-time transport protocol (Real-time Transport Protocol, RTP).
The service terminal 104 is connected with the audio service system 105 and the video service system 106 through application program (Application Program Interface, API) interfaces, and performs establishment of related service media channels by calling resources reserved by the audio service system and the video service system.
The service terminal 104 establishes a connection with the audio/video service continuity switching system 107 through signaling, and is used for performing media negotiation with the control counter subsystem 1072 in the audio/video service continuity switching system 107.
The service terminal 104 may be a service system client such as a voice customer service system and a conference system, or may be a user terminal.
The audio service system 105 is configured to reserve system resources required for performing an audio call between the user terminal and the service terminal. Such as voice customer service systems, audio conferencing systems, etc.
And the video service system 106 is used for reserving system resources required by video call between the user terminal and the service terminal. Such as video customer service systems, video conferencing systems, etc.
The signaling capturing subsystem 1071 is configured to extract SIP/SDP signaling in the signaling system 102, and when audio/video switching occurs, the signaling capturing subsystem can sense and trigger an API interface in advance, and notify the switching behavior to the control anti-subsystem 1072.
The control counter subsystem 1072 is connected with the audio service system 105 and the video service system 106 through API interfaces, and is used for requesting the audio service system 105 and the video service system to reserve resources required for performing audio and video service interaction.
In some embodiments, the signaling capture subsystem 1071 may be divided into a SIP parsing module, an event subscription module, a SIP proxy module, and a SIP processing module according to the functions it employs.
In some embodiments, the control anti-rotor system 1072 may be divided into a time processing module, a service orchestration module, a service mapping module, and a service control module according to the functions it employs.
In some embodiments, with continued reference to fig. 2, based on the architecture of the audio and video service system, when the user terminal initiates an audio call or a video call request for the first time, a specific process of constructing a corresponding audio and video service is as follows: after the signaling system 102 completes the registration and access processes, the user terminal 101 initiates an audio and video service request to be transmitted in a signaling manner; after capturing the audio and video service request, the signaling system 102 routes the audio and video service request to the signaling capturing subsystem 1071 in the audio and video service continuity switching system 107 in a signaling manner; the signaling capture subsystem 1071 establishes a session negotiation announcement based on subscription information contained in the audio video service request and sends the session negotiation announcement to the control anti-subsystem 1072.
The control anti-subsystem 1072 selects a corresponding service system according to the service to be established in the session negotiation announcement; for example, the audio service system 105 is selected if the service to be set up is an audio service, and the video service system 106 is selected if the service to be set up is a video service; forwarding the session negotiation notification to the service terminal 104 after the service system is selected; in case of successfully receiving the session negotiation notification, the service terminal 104 establishes a corresponding audio channel or video channel. Thus, the user terminal 101 can perform audio call or video call with the service terminal 104 through the audio/video media channel.
For example, when fig. 2 is mapped to a system structure of the VOLTE video customer service system, the user terminal 101 is a VOLTE mobile phone terminal; the signaling system 102 is an IMS network signaling processing part and is mainly responsible for the registration procedure of the VOLTE mobile phone terminal; the media service system 103 is an IP multimedia subsystem (IP Multimedia Subsystem, IMS) network and an Inter-network session border controller (Inter-network Session BordorControllor, I-SBC); the service terminal 104 is a customer service system; the VOLTE mobile phone terminal and the customer service system are accessed to the IMS network and the I-SBC so as to exchange and transmit media streams.
The VOLTE mobile phone terminal initiates an audio service request and transmits the audio service request in a signaling mode, and after receiving the request, the IMS network signaling processing part routes the request to a signaling capturing subsystem in the audio service continuous line switching system in a signaling mode; the signaling capturing subsystem establishes a session negotiation notice according to subscription information contained in the audio service request, and sends the session negotiation notice to the control inversion subsystem; the control anti-subsystem selects the audio service system as the service logic service unit and forwards the session negotiation notice to the customer service system; after the customer service system processes the audio information, an audio media stream of the terminal-ISBC-customer service system is established, and negotiation success information is fed back to the VOLTE mobile phone terminal.
The method for switching the audio call to the video call provided by the embodiment of the invention is described in detail below with reference to the accompanying drawings.
Fig. 3 is a flowchart of a method for switching an audio call to a video call according to an embodiment of the present invention. As shown in fig. 3, the method comprises the steps of:
s101, the audio and video service continuity switching system receives first request information of a user terminal.
The first request information is used for requesting to switch the call between the user terminal and the service terminal from an audio call to a video call.
In some embodiments, the first request information includes identification information of a call between the user terminal and the service terminal and configuration information of the video call.
In some embodiments, the identification information of the call is a mobile phone number of the user terminal, or a registered account number of the user terminal, or an identifier with user characteristic information such as an IP address of the user terminal.
In some embodiments, the configuration information for the video call includes a definition of the video picture, a size of the video picture, a transmission rate of the video picture, and the like.
In some embodiments, the first request information of the user terminal is mainly generated in the process of performing an audio call by the user terminal, and specifically, the user can actively send the first request information to the audio/video service continuity switching system through manually operating the terminal device; or when the terminal equipment senses the action of switching the audio call into the video call, triggering a related program and sending first request information to the audio/video service continuity switching system.
Wherein the first request information may be transmitted by SIP/SDP signaling.
For example, in the case where the audio call needs to be switched to the video call due to a service requirement during the audio call, the VOLTE mobile phone terminal may initiate an Update request to modify the media parameter to the video, and send the request to the IMS network signaling processing part. The IMS network routes the Update request to an audio and video service continuity switching system.
In this way, the signaling transmission mode is beneficial to protecting the privacy security of the user and is also convenient for the receiving and processing of the signaling capturing subsystem.
With continued reference to fig. 2, based on the architecture of the audio/video service system, the implementation manner of step S101 is specifically as follows: when the user terminal 101 and the service terminal 104 perform an audio call, the user terminal 101 initiates first request information for switching the audio call to the video call, and transmits the first request information to the signaling capturing subsystem 1071 through the signaling system 102 in a signaling manner.
For example, in the case that the user terminal 101 is a VOLTE mobile phone terminal, the signaling system 102 is an IMS network signaling processing part, the media service system 103 is an IMS network and an Inter-network session border controller (Inter-network Session Bordor Controllor, I-SBC), and the service terminal 104 is a customer service system, the VOLTE mobile phone terminal initiates the first request information; the IMS network signaling processing portion receives the first request information and routes the first request information to the signaling acquisition subsystem by signaling.
S102, responding to the received first request information, and sending second request information to the video service system by the audio/video service continuity switching system.
The second request information is used for requesting the video service system to reserve system resources required by video call between the user terminal and the service terminal.
In some embodiments, the second request information includes identification information of a call between the user terminal and the service terminal and configuration information of the video call. The system resources include bandwidth resources, video processing resources, and video quality inspection resources.
In some embodiments, with continued reference to fig. 2, based on the architecture of the audio/video service system, the implementation manner of step S102 is specifically: after receiving first request information initiated by the user terminal to switch the call between the user terminal 101 and the service terminal 104 from the audio call to the video call, the signaling capturing subsystem 1071 forwards the first request information to the control inversion subsystem 1072; the control anti-subsystem 1072 sends the second request message to the video service system 106; the video service system 106 reserves system resources required for video call between the corresponding user terminal 101 and service terminal 104 according to the call identification information and the video call configuration information in the second request information.
Therefore, the service terminal can reserve the system resources required by the video call between the user terminal and the service terminal based on the video service system, and establish a video media channel for the user terminal and the service terminal.
S103, the audio and video service continuity switching system receives second response information from the video service system.
The second response information is used for determining that system resources are reserved by the audio and video service continuity switching system.
In some embodiments, with continued reference to fig. 2, based on the architecture of the audio/video service system, the implementation manner of step S103 is specifically: after the video service system 106 successfully reserves the system resource, the second response information is sent to the audio/video service continuity switching system 107. Thus, the audio/video service continuity switching system 107 can continue the operation of switching the audio call to the video call, thereby reducing the waiting time.
S104, the audio and video service continuity switching system responds to the received second response information and sends third request information to the service terminal.
The third request information is used for indicating the service terminal to use the system resource to create the video media channel.
In some embodiments, with continued reference to fig. 2, based on the architecture of the audio/video service system, the implementation manner of step S104 is specifically: after receiving the second response information, the control counter subsystem 1072 in the audio/video service continuity switching system 107 sends third request information to the service terminal 104, where the third request information is used to instruct the service terminal 104 to create a video media channel using system resources.
In this way, a video call can be made between the user terminal 101 and the service terminal 104 based on the video media channel.
