2. Video networking packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
DA SA Reserved Payload CRC
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
DA SA Reserved Label Payload CRC
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
Based on the characteristics of the video network, the application of the audio and video call is more and more extensive, and in practice, users often need to call the video network terminal through an internet terminal to establish video call connection with the video network terminal. For example, a user needs to call a video network terminal by using an internet terminal of an H323 protocol, and due to cross-network calling, when the internet terminal calls the video network terminal, in order to accurately locate the video network terminal, it is necessary to specify which protocol the video network terminal is specifically connected to, and to specify a unique identifier of the video network terminal in the video network, so as to ensure that the call is successful. For example, a call address of "internet IP address of the protocol server + # #91+ video network terminal number" needs to be input in an address field of the internet terminal of the H323 protocol to ensure that a call is made to the video network terminal. However, although such character string combination accurately expresses the position of the called terminal, the calling process is cumbersome, and when the calling address is input, an error is easily input, which results in unsuccessful calling, thereby reducing the efficiency of video call.
Based on this, the applicant proposes one of the inventive concepts of the present application, in which the coordination server may communicate with the gatekeeper server, and receive a call request signaling that conforms to a preset call protocol and is sent by the internet terminal, where the call request signaling may include a video networking number, and then send a registration confirmation signaling including the video networking number to the gatekeeper server to determine whether the video networking number targeted by the call request signaling is registered in the gatekeeper server, and if so, may establish a video call connection according to the call request signaling. Furthermore, the internet terminal can directly position the video network terminal through the video network number, so that the calling mode is simplified, and the efficiency of video call is improved.
Referring to fig. 5, a communication environment diagram of a method for establishing a video call connection according to an embodiment of the present invention is shown, and as shown in fig. 5, the communication environment diagram includes a collaboration server, a gatekeeper server, a video networking terminal, and an internet terminal, where the collaboration server, the gatekeeper server, the video networking terminal, and the internet terminal form a video call system.
The protocol conversion server can perform the functions of converting a streaming media protocol and encapsulating audio and video data packets, and is mainly responsible for converting an RAS protocol, a video networking protocol and an Internet protocol in the application. The RAS protocol is mainly used for communication between the gateway and the gatekeeper, the gateway can search the home gateway by utilizing RAS signaling, register the information of the gateway with the gatekeeper, inquire the authority of a user and the like from the gatekeeper when a call starts.
In this embodiment, the gatekeeper server may communicate with the cooperative server, and the gatekeeper server may communicate with the cooperative server by using an RAS protocol, where the RAS protocol is a signaling control protocol in an h.323 protocol family and may be responsible for controlling registration with the gatekeeper server. The gatekeeper server can register the equipment in the video call system so as to manage the equipment in the video call system and complete the work of address translation and the like. The video network terminal is a device for audio and video transmission, playing and the like in the video network, and the protocol adopted by the video network terminal is a video network protocol, and specifically, the video network terminal can be, but is not limited to, a set top box.
In this embodiment, the internet terminal may be an H323 terminal, and the H323 terminal is a multimedia terminal defined by an h.323/t.120 protocol, and may provide real-time video and audio bidirectional communication, and may be, but is not limited to, a smart phone, a tablet computer, and a personal computer.
In the video call system, the internet terminal is deployed in the internet, the video network terminal is deployed in the video network, and the protocol conversion server can be simultaneously communicated with the video network and the internet so as to forward data between the video network and the internet.

Referring to the communication environment shown in fig. 5, a method for establishing a video call connection according to an embodiment of the present invention may be applied to a collaboration server, where the video network terminal is configured with a video network address. The video network address refers to an address of a video network terminal in the video network, and comprises an IP address, a video network number and a video network identification number of a protocol conversion server connected with the video network terminal, wherein the video network identification number is used for identifying the identity of a called terminal as the identity of the video network terminal. For example, the video networking address may be "XMCUip # # 9100013".
Specifically, before the internet terminal starts to call, the internet terminal and the video network terminal may be registered, as shown in fig. 6, a flowchart illustrating a step of registering the video network terminal by the coordination server is shown, and the method specifically includes the following steps:
step S601, determining whether the cooperative server is configured with the gatekeeper application based on a pre-stored configuration file.
In this embodiment, the configuration file may be understood as a system configuration file of the cooperative server itself, and the gatekeeper application may be understood as a gatekeeper object set in the configuration file, where the gatekeeper object may provide a local client service for the cooperative server, that is, when the gatekeeper object is configured, the cooperative server may have an identity of the gatekeeper client, so as to actively initiate registration to the gatekeeper server with the identity of the gatekeeper client.
Step S602, when it is determined that the coordination server is configured with the gatekeeper application, a video networking number preset for the video networking terminal is read from the configuration file.
In this embodiment, when determining that the gatekeeper application is configured, it indicates that the collaboration server has the identity of the gatekeeper client, and may read, from the configuration file, a video networking number preconfigured for the video networking terminal, where the number may be written into the configuration file in advance by a manager. Specifically, the number may be an E164 number, and a destination number may be included in the video network number, where the destination number may be used to identify that a terminal corresponding to the video network number is located in the video network, indicating that the terminal belongs to the video network. For example, the video networking number of the video networking terminal may be configured as 9100013, where 91 is the destination number used to confirm that the identity of the registered party is the video networking terminal and 00013 is the number of the video networking terminal used to identify the video networking terminal.
Step S603, generating a registration request signaling including the video networking number.
In this embodiment, when determining that the configuration file is configured with the gatekeeper application and reading the configured video networking number, the cooperative server may automatically start the thread of active registration to send the registration request signaling. The registration request signaling may include a preconfigured internet of view number, where the registration request signaling may be registration signaling of the RAS protocol.
Step S604, sending the registration request signaling to the gatekeeper server, where the gatekeeper server is configured to respond to the registration request signaling and correspond the video networking address to the video networking number.
In this embodiment, after the cooperative forwarding server sends the registration request signaling to the gatekeeper server through the thread of active registration, the gatekeeper can map the video networking address configured by the video networking terminal to the video networking number in the registration request signaling by the server, so as to complete the registration of the video networking terminal. Thus, the view network address corresponds to a view network number.
In practice, the cooperative server may determine to complete registration of the video-networking terminal after receiving a registration success signaling returned by the gatekeeper server. Specifically, after the gatekeeper server replies the RCF to the coordination server, the registration is successful.
Accordingly, in an alternative example, the internet terminal may also register with the gatekeeper server. Specifically, the internet terminal may transmit a registration request including an internet number to the gatekeeper server, and the gatekeeper server may map an internet address of the internet terminal to the internet number according to the registration request to complete registration of the internet terminal.
After the video network terminal and the internet terminal complete registration, the internet terminal may call the video network terminal, and may further execute a method for establishing a video call connection in the embodiment of the present application, referring to fig. 7, a flowchart of steps of a method for establishing a video call connection in an embodiment of the present invention is shown, and as shown in fig. 7, the method may specifically include the following steps:
step S701, receiving a call request signaling which is sent by the Internet terminal and accords with a preset call protocol, wherein the call request signaling comprises a video networking number.
The preset call protocol may be an H225 call protocol, and the H225 call protocol is a protocol standard of video telephony. Specifically, the H225 protocol is a signaling control protocol in the H323 protocol cluster, and is responsible for call control/call setup. The call request signaling can be encapsulated by an internet protocol, and the protocol conversion server can analyze the call request signaling when receiving the call request signaling, so as to obtain the video networking number carried by the call request signaling.
In practice, the internet-of-view number may be entered by the user into the call address bar of the internet terminal, so that the internet terminal generates call request signaling including the internet-of-view number.
Step S702, responding to the call request signaling, generating a registration query signaling including the video network number, and sending the registration query signaling to the gatekeeper server.
The gatekeeper server is used for responding to the registration inquiry signaling and determining whether the video networking number is a number corresponding to the video networking address.
In this embodiment of the application, in response to the call request signaling, it may be understood that after the corotation server receives the call request signaling, the corotation server may generate, based on the call request signaling, a registration query signaling including the video networking number, and send the registration query signaling to the gatekeeper server.
Specifically, the negotiation server may encapsulate the call reQuest signaling in an ARQ (Automatic Repeat-reQuest) signaling to obtain a registration query signaling, so as to send the registration query signaling to the gatekeeper server. The gatekeeper server can read the video network number from the registration inquiry signaling after receiving the registration inquiry signaling, and determine whether the video network number corresponds to the video network address.
Step S703, receiving a registration confirmation signaling returned by the gatekeeper server for the registration query signaling.
Wherein the registration confirmation signaling is generated by the gatekeeper server upon determining that the video networking number corresponds to the video networking address.
In the embodiment of the application, the gatekeeper server determines that the video networking number corresponds to the video networking address, and then indicates that the video networking number is a number mapped by the video networking address, so that the called video networking terminal is successfully registered on the gatekeeper server, and the protocol conversion server can directly determine the corresponding video networking terminal through the video networking number. At this time, the gatekeeper server may return a registration confirmation signaling, e.g., an ACF (assisted confirm) signaling, to the corotation server.
Optionally, after the coordination server receives the registration confirmation signaling, the IRR information may be replied to the gatekeeper server to inform the gatekeeper server that the registration confirmation signaling is confirmed.
Step S704, establishing a video call connection between the internet terminal and the video network terminal based on the registration confirmation signaling and the call request signaling.
When the protocol conversion server receives the registration confirmation signaling, the protocol conversion server can determine the video network terminal corresponding to the video network number in the call request signaling according to the registration confirmation signaling, that is, the protocol conversion server can identify the video network number, and then can respond to the call request signaling sent by the internet terminal to establish the video call connection between the internet terminal and the video network terminal.
Specifically, because the registration confirmation signaling can represent that the video network terminal has successfully registered on the gatekeeper server, the video network terminal can be practically managed by the gatekeeper server, and the protocol server can determine the video network terminal according to the video network number.
With reference to the foregoing embodiment, in an optional embodiment, the video call system may further include a video networking server, and then in step 704, the step of establishing a video call connection between the internet terminal and the video networking terminal may specifically include the following steps:
step S7041, responding to the registration confirmation signaling, converting the call request signaling into video networking call signaling conforming to a video networking protocol.
In this example, when the registration confirmation signaling is received, the call request signaling previously sent by the internet terminal may be converted into the video networking call signaling conforming to the video networking protocol. Specifically, since the call request signaling is encapsulated by the internet protocol, during the conversion, the internet protocol header of the call request signaling may be removed and replaced with the video networking protocol header to obtain the video networking call signaling. So that the video networking call signaling can be transmitted within the video networking to the video networking terminal.
Step S7042, the video networking call signaling is sent to the video networking server.
The video network server is used for sending the video network calling signaling to the video network terminal, and the video network terminal is used for generating a calling reply signaling based on the video network calling signaling and returning the calling reply signaling to the video network server.
In this example, the video network server is a core server in the video network, and may provide services such as data forwarding for high-definition audio and video transmission in the video network. In practice, the video network terminal and the video network server can be in communication connection, and the video network server and the protocol conversion server can be in communication connection.
When the protocol conversion server generates the video networking call signaling, the video networking call signaling can be sent to the video networking server, and the video networking server can forward the video networking call signaling to the video networking terminal. When the video networking terminal receives the video networking call signaling, in practice, the video networking call signaling can be displayed to a video networking terminal user, and a call reply signaling is returned to the video networking server according to the answering operation performed by the user, and then the video networking server sends the call reply signaling to the protocol conversion server.
Step S7043, receiving the call reply signaling returned by the video network server, and converting the call reply signaling into a target call reply signaling conforming to the preset call protocol.
In this example, when the protocol conversion server receives the call reply signaling, since the call reply signaling is a signaling conforming to the video networking protocol, the call reply signaling may be converted into a signaling conforming to the internet protocol, specifically, the video networking protocol header of the call reply signaling may be removed, and the call reply signaling from which the video networking protocol header is removed may be converted into a signaling conforming to a preset call protocol, for example, a reply signaling of the H225 protocol, and then the internet protocol header is added, thereby obtaining the target call reply signaling.
Step S7044, the target call reply signaling is sent to the Internet terminal to complete the establishment of the video call connection.
In practice, the collaboration server may send the target call reply signaling to the internet terminal, and when receiving the target call reply signaling, the internet terminal establishes a video call connection between the internet terminal and the video network terminal, that is, a data channel for transmitting audio and video data is established between the video network terminal and the internet terminal, thereby realizing a successful call of the internet terminal to the video network terminal.
After the video call connection is established, audio and video data can be transmitted between the video network terminal and the internet terminal. Specifically, the following steps may be included:
the protocol conversion server can receive first video networking audio and video data which are sent by the video networking server and collected by the video networking terminal, convert the first video networking audio and video data into first internet audio and video data which accord with an internet protocol, and finally send the first internet audio and video data to the internet terminal.
Meanwhile, the protocol conversion server can receive second internet audio and video data sent by the internet terminal, convert the second internet audio and video data into second video networking audio and video data conforming to a video networking protocol, and finally send the second video networking audio and video data to the video networking server so that the video networking server sends the second video networking audio and video data to the video networking terminal.
Through the steps, the cooperative conversion server can transmit audio and video data between the video networking terminal and the Internet terminal after the video call connection between the video networking terminal and the Internet terminal is established, so that the normal operation of the video call is ensured.
With reference to the foregoing embodiment, in an optional embodiment, after step S604, the following step may be specifically included:
step S705, receiving a call end signaling that conforms to the preset protocol and is sent by the internet terminal.
In practice, the coordination server may receive a call end signaling, where the call end signaling may be generated by the internet terminal when detecting that the video call is hung up by the user of the internet terminal, where both the call end signaling and the call request signaling may be signaling conforming to a preset call protocol, such as signaling of an H225 protocol.
Step S706, responding to the call ending signaling, disconnecting the video call connection between the Internet terminal and the video networking terminal, and generating a management releasing signaling, wherein the management releasing signaling comprises the video networking number.
In practice, the protocol conversion server may disconnect the video call connection between the internet terminal and the video network terminal in response to the call end signaling, and specifically, the protocol conversion server may interrupt forwarding of the audio and video data between the video network terminal and the internet terminal.
Because a plurality of virtual terminals can be arranged in the protocol conversion server in the video network, the virtual terminals can be understood as external data communication interfaces of the video network server. In this embodiment, the collaboration server may allocate a virtual terminal to the video networking terminal, so as to interface the video networking terminal through the virtual terminal, that is, communicate with the video networking terminal through the virtual terminal.
When the protocol conversion server receives the call ending signaling, the butt joint relation between the video networking terminal and the virtual terminal can be released, so that the video call connection between the video networking terminal and the internet terminal is disconnected. Therefore, the virtual terminal which is docked before the video network terminal is in an idle state, and the coordination server can dock the virtual terminal with the video network terminal which is newly accessed subsequently.
When the video call connection is disconnected, the coordination server may also generate a release management signaling, where the signaling may carry a video networking number, and in practice, the release management signaling may be a DRQ (discrete request) signaling to indicate that the video networking terminal needs to be released from the management of the gatekeeper server.
Step S707, sending the release management signaling to the gatekeeper server.
The gatekeeper server is used for responding to the unmanaged signaling and canceling the corresponding relation between the video networking number and the video networking address.
In practice, the coordination server may send the deregistration signaling to the gatekeeper server, and when receiving the deregistration signaling, the gatekeeper server may cancel the corresponding relationship between the video networking number and the video networking address, that is, cancel the mapping between the video networking number and the video networking address, thereby enabling the video networking terminal to be separated from the management of the gatekeeper server.
With reference to the foregoing embodiment, in an optional embodiment, after the corotation server sends the registration query signaling to the gatekeeper server, if the gatekeeper server confirms that the video networking number does not correspond to the video networking address, the corotation server may perform the following steps:
step S703' receives a registration error signaling returned by the gatekeeper server for the registration query signaling.
Wherein the registration error signaling is generated by the gatekeeper server upon determining that the view networking number is not a number corresponding to the view networking address.
Step S704', based on the registration error signaling, generating a prompt message, and sending the prompt message to the Internet terminal, where the Internet terminal is used to display the prompt message.
In practice, the protocol conversion server may receive the registration error signaling, and when receiving the registration error signaling, it indicates that the video network number is not the number mapped by the video network address, thereby indicating that the called video network terminal may not register successfully on the gatekeeper server, and may also be the video network number input on the internet terminal is wrong. At this moment, the cooperation transfer server can generate prompt information and send the prompt information to the internet terminal, so that a user of the internet terminal can know that the call is unsuccessful according to the prompt information, and the user can conveniently input a correct video networking number or know the registration state of the video networking terminal to be called.
Accordingly, in this optional example, the registration error signaling may include unregistered information or number error information, where the unregistered information ensures that the terminal of the video network is unregistered, and the number error information indicates that an error occurs in the video network number. The protocol conversion server can analyze the registration error signaling, and when determining that the registration error signaling includes unregistered information, the protocol conversion server can register the video network terminal, and the protocol conversion server specifically includes the following steps:
step S705', in response to the registration error signaling, determining whether the gatekeeper application is configured from a pre-stored configuration file.
The process of step S705' is similar to the process of step S601, and is not described herein again.
Step S706', when it is determined that the coordination server is configured with the gatekeeper application, a target registration request signaling including the video networking number is generated.
The process of step S706' is similar to the process of step S603, and is not described herein again.
Step S707', based on the gatekeeper application, a registration thread is enabled, and the target registration request signaling is sent to the gatekeeper server through the registration thread, where the gatekeeper server is configured to respond to the target registration request signaling and correspond the video networking address to the video networking number.
The process of step S707' is similar to the process of step S604, and is not described herein again. Through the step, the called video networking terminal can be enabled to be managed by the gatekeeper server.
Step S708', receiving a registration success signaling returned by the gatekeeper after the address of the video networking corresponds to the video networking number.
Step S709', based on the registration success signaling and the call request signaling, establishing a video call connection between the internet terminal and the video network terminal.
Under the condition, the cooperative conversion server can determine that the video network terminal is successfully registered through the registration success signaling, and represents that the called video network terminal is timely brought into the management of the gatekeeper server, so that the cooperative conversion server can immediately establish the video call connection between the internet terminal and the video network terminal. Specifically, the process of step S709' is similar to the process of step S704, and is not described herein again.
Example two
In this embodiment, another method for establishing a video call connection is disclosed, and a communication environment diagram of the method of this embodiment is shown in fig. 5, specifically, the method of this embodiment may be applied to a gatekeeper server, so that the gatekeeper server implements the method for establishing the video call connection, and the video network terminal is configured with a video network address.
First, the gatekeeper server may perform the following steps of registering the video network terminal in advance, including the following steps:
and step S001, receiving the registration request signaling sent by the cooperative conversion server.
The registration request signaling is generated by the protocol conversion server when the protocol conversion server is determined to be configured with a gatekeeper application based on a pre-stored configuration file, and the registration request signaling comprises a video networking number preset for the video networking terminal.
The specific process of step S001 may refer to the description of step S601, and is not described herein again.
And step S002, responding to the registration request signaling, and corresponding the video networking number with the video networking address.
The specific process of step S002 may refer to the description of step S602, and is not described herein again.
After completing the registration of the video networking terminal, the gatekeeper server may return a successful registration signaling, such as RCF (registration reply) signaling, to the corotation server to inform the corotation server of the successful registration.
Referring to fig. 8, a flowchart illustrating steps of a method for establishing a video call connection executed by a gatekeeper server after successful registration is shown, and as shown in fig. 8, the method specifically includes the following steps:
step S801, receiving the registration query signaling sent by the collaboration server.
The registration query signaling is generated by the protocol conversion server when receiving a call request signaling which is sent by the internet terminal and accords with a preset call protocol, and the registration query signaling comprises a video networking number acquired from the call request signaling.
The process of generating and sending the registration query signaling by the cooperative conversion server may refer to the description in step S701, and is not described herein again.
Step S802, responding to the registration inquiry signaling, and determining whether the video network number is a number corresponding to the video network address.
In this embodiment, the gatekeeper server may read the video networking number from the registration query signaling, and may translate the video networking number into the target video networking address, and may further compare the target video networking address obtained after the translation with the video networking address configured for the video networking terminal to determine whether the two are the same address, and if so, characterize that the video networking number is a number corresponding to the video networking address, indicating that the video networking terminal is a terminal successfully registered on the gatekeeper server. If not, the representation video networking number is not the number corresponding to the video networking address, and the fact that the video networking terminal is possibly not successfully registered on the gatekeeper server is identified, or the video networking number is possibly an error number is identified.
Step S803, when it is determined that the video networking number is a number corresponding to the video networking address, a registration confirmation signaling is generated.
Step S804, sending the registration confirmation signaling to the coordination server.
And the protocol conversion server establishes video call connection between the Internet terminal and the video networking terminal based on the registration confirmation signaling and the call request signaling.
When the video networking number is determined to be the number corresponding to the video networking address, the gatekeeper server can send a registration confirmation signaling to the protocol conversion server to inform the protocol conversion server that the video networking terminal is successfully registered. Specifically, the process of step S803 may refer to the description of step S703, and the process of step S804 may refer to the description of step S704, which is not repeated herein.
In this embodiment, the gatekeeper server may complete registration of the video networking terminal according to the registration request of the protocol server to map the video networking address of the video networking terminal to the video networking number, so that the internet terminal may call the video networking number to establish video call connection with the video networking terminal. Furthermore, the length of the address input by the user in the call address bar is simplified, the call process is simplified, and the efficiency of video call is improved.
Optionally, in this embodiment, the method may further include the following steps:
step S803', when it is determined that the video network number is not the number corresponding to the video network address, a registration error signaling is generated.
Step S804', sending the registration error signaling to the cooperative server.
Specifically, when determining that the video networking number is not the number corresponding to the video networking address, the gatekeeper server may send a registration error signaling to the protocol conversion server to inform the protocol conversion server that the video networking terminal is not registered. In this case, the steps S001 to S002 may be executed to register the unregistered terminal of the internet of view so as to ensure that the terminal of the internet of view can successfully call the terminal of the internet of view.
In an optional implementation manner, in combination with the above example of the second embodiment, after step S804, the following step may be further included:
step S805, receiving the release management signaling sent by the collaboration server.
The unmanaged signaling is generated by the protocol conversion server when the call ending signaling which is sent by the internet terminal and accords with the preset protocol is received, and the video call connection between the internet terminal and the video network terminal is disconnected, wherein the unmanaged signaling comprises the video network number.
Specifically, the process of generating the release management signaling by the collaboration server may refer to the description of step S705 and step S706, which is not described herein again.
Step S806, in response to the release management signaling, canceling the corresponding relationship between the video networking number and the video networking address.
In this example, after receiving the deregistration signaling, the gatekeeper server may cancel the correspondence between the video networking number and the video networking address, that is, the video networking address is no longer mapped to the video networking number. Thereby, the video network terminal is separated from the management of the gatekeeper server.
Referring to fig. 9, a complete flow diagram of a method for establishing a video call connection in an exemplary embodiment is shown, in fig. 9, an H323 protocol conversion server is a server that can perform audio and video communication using an H323 protocol.
Specifically, the H323 cooperation server may send an H225 registration protocol (i.e., registration request signaling) to the gatekeeper server to register the video networking terminal.
Then, the gatekeeper server replies H225 registration reply signaling to the H323 coordination server to inform the H323 coordination server that the video network terminal has been successfully registered.
Further, the H323 protocol conversion server may receive a call request of the H225 sent by the internet terminal, where the call request includes a video networking number, and the H323 protocol conversion server may further send a registration query signaling to the gatekeeper server to confirm whether the video networking number is a successfully registered number.
Then, when receiving the registration confirmation signaling returned by the gatekeeper server, the H323 coordination server may send a video networking call signaling of a video networking call protocol to the video networking server, and the video networking server sends the video networking call signaling to the video networking terminal.
And then, the video network terminal replies a video network reply protocol (namely a video network reply signaling) to the video network server, and the video network server sends the video network reply protocol to the H323 protocol conversion server.
Finally, the H323 protocol conversion server converts the video network reply protocol into an H225 call reply (i.e. a target call reply signaling), and sends the H225 call reply to the Internet terminal so as to establish a video call connection between the video network terminal and the Internet terminal.
