Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flowchart illustrating steps of a method for processing a video call according to an embodiment of the present invention is shown, where the method for processing a video call is applicable to a GIS, and the GIS can be communicatively connected to a network management system and a conference management system, respectively. The processing method of the video call specifically comprises the following steps:

step 101, in response to a first selection operation of a user on a terminal list imported from a network management system in advance, acquiring related information of a first terminal.

In an embodiment of the invention, the GIS is communicatively coupled to a network management system. The network management system can import a terminal list to the GIS, and the terminal list can include area information, number information, affiliated organization information, type information, address information, network card information, creation time information, modification time information, and principal information of the terminal, and the like.

For example, the terminal list includes the following information of each terminal:

zonedevno: area code + device number

Zoneno: area code

Ssjgid: affiliated organization id

equipmentad: device corresponding area id

ip: IP address

type: type (B)

address: address

And long: longitude (G)

lat: latitude

mac: MAC address

createTime: creation time

modifyTime: modifying time

primary: person in charge of unit

In this step 101, when the user performs a selection operation on a certain terminal in the terminal list, the terminal corresponding to the selection operation is used as the first terminal in response to the selection operation, and further, the related information of the first terminal is acquired.

It should be noted that the first terminal may be an initiator terminal of a video call, and the first terminal and the GIS belong to the same autonomous region. The related information of the first terminal may include at least number information of an autonomous area to which the first terminal belongs and number information of the first terminal.

And 102, responding to a second selection operation of the user aiming at the autonomous area list imported from the network management system in advance, and acquiring the area information of the second terminal.

In an embodiment of the present invention, after the user selects the originator terminal of the video call, the user then selects the autonomous area to which the recipient terminal of the video call belongs. Therefore, the user executes a second selection operation for the autonomous area list imported from the network management system, and takes the autonomous area corresponding to the second selection operation as the autonomous area to which the second terminal belongs, thereby acquiring area information of the second terminal. It should be noted that the first terminal and the second terminal belong to different autonomous areas.

In the embodiment of the present invention, the network management system may import an autonomous area list to the GIS, in addition to the terminal list to the GIS, where the autonomous area list may include name information, organization structure information, address information, creation time information, database information, and number information of the autonomous area.

For example, the autonomous area list includes the following information of each autonomous area:

id: primary key ID

And Pid: parent ID

Name: name of autonomous area

Ip: IP address

Regiogid: organization structure ID

Xxdz: detailed address

Longituude: longitude (G)

Latitude: latitude

Createtime: creation time

Dbname: name of database

Dbhost: database address

Dbport: database port

Dbpwd: database password

Zonecode: region code

And 103, receiving the number information of the second terminal input by the user.

In the embodiment of the present invention, the user may manually input the number information of the second terminal, or the user may select the second terminal from the terminal list in the GIS, so as to obtain the number information of the second terminal. The embodiment of the present invention does not specifically limit the technical means for receiving the number information of the second terminal.

And step 104, calling an interactive interface of the conference management system, and sending the relevant information of the first terminal, the area information of the second terminal and the number information of the second terminal to the conference management system, so that the conference management system can execute the video call operation between the first terminal and the second terminal according to the relevant information of the first terminal, the area information of the second terminal and the number information of the second terminal.

In an embodiment of the invention, the conference management system may provide an interaction interface for GIS calls. And the GIS calls the interactive interface and sends the related information of the first terminal, the area information and the number information of the second terminal to the conference management system so that the conference management system can execute the video call operation between the first terminal and the second terminal according to the related information of the first terminal, the area information and the number information of the second terminal.

In a preferred embodiment of the present invention, the GIS invokes an interactive interface provided by a conference management service of the conference management system, sends the relevant information of the first terminal and the area information and the number information of the second terminal to a conference scheduling service of the conference management system, so that the conference scheduling service generates a scheduling service signaling according to the relevant information of the first terminal and the area information and the number information of the second terminal, and transmits the scheduling service signaling to the core server. The core server can execute the video call operation between the first terminal and the second terminal according to the scheduling service signaling.

Based on the above description about a method for processing a video call, a method for inter-area dialing a video call based on a video network is introduced below. Referring to fig. 2, a flow diagram of a method for cross-domain video call based on video networking is shown. And the GIS acquires the autonomous area list data and the terminal list data through a network management system. A user selects a terminal of a local autonomous region in the GIS as an initiator terminal of a video call, and the user selects a terminal of a non-local autonomous region in the GIS as a receiver terminal of the video call. And the GIS performs data interaction on the relevant information of the initiator terminal and the relevant information of the receiver terminal with the conference management system. Specifically, the conference management system provides an interactive interface to the outside. The GIS transmits the relevant information of the initiator terminal and the relevant information of the receiver terminal to a conference management system through an interactive interface, a scheduling service in the conference management system generates a scheduling service signaling according to the relevant information of the initiator terminal and the relevant information of the receiver terminal, and transmits the scheduling service signaling to a video networking core server through a video networking, and the video networking core server realizes the video call service between the initiator terminal and the receiver terminal.

In practical application, when the GIS performs data interaction with the conference management system, data including the following information may be transmitted to the conference management system:

userId: operating user id

userGroupID: operating user group id

name: video call service name

boxnum: number of initiator terminal

destboxnum: receiver terminal number

dev 1: initiator terminal complete 8-digit equipment number

dev 2: complete 8-digit equipment number of receiver terminal

area 1: initiator terminal area number

area 2: receiver terminal area number

In practical application, the dispatch service can be understood as a dispatch service system based on a video networking protocol, and is mainly used for realizing video call service between terminals in a video networking. After receiving the scheduling service signaling, the scheduling service may address the initiator terminal according to the MAC address of the initiator terminal therein, and transmit related information of the initiator terminal and related information of the receiver terminal. And addressing to the receiver terminal according to the MAC address of the receiver terminal, and transmitting the relevant information of the initiator terminal and the relevant information of the receiver terminal. The initiator terminal addresses the receiver terminal in the video networking protocol according to the related information of the receiver terminal, and correspondingly executes the calling function of the video call. The receiving party terminal receives the calling instruction to execute the called function, displays the called function and can select to answer or hang up.

Referring to fig. 3, a schematic diagram of a method for cross-regional video call dialing based on the internet of vision in the embodiment of the present invention is shown. The network management system performs cutover operation on a plurality of terminals including a first terminal and a second terminal to form an autonomous area list divided according to autonomous areas to which the plurality of terminals belong. The GIS acquires an autonomous area list and a terminal list from a network management system. The user can select a local default initiator terminal through the front end of the GIS and select a receiver terminal. And the GIS calls an interactive interface of the conference management system to transmit the relevant information of the initiator terminal and the relevant information of the receiver terminal to the conference management system. The conference management system manages the initiator terminal and the receiver terminal together through the network management system. The conference management service in the conference management system transmits the relevant information of the initiator terminal and the relevant information of the receiver terminal to the conference scheduling service in the conference management system, the conference scheduling service sends a scheduling service signaling to the video networking core server, and the video networking core server acquires the state information of the initiator terminal and the receiver terminal through the network management system, so as to execute the video call service dialed by the initiator terminal to the receiver terminal and return the state information of the initiator terminal and the receiver terminal to the network management system.

The processing scheme of the video call provided by the embodiment of the invention is applied to a GIS (geographic information system), and the GIS can be in communication connection with a network management system and a conference management system. The network management system can manage the terminal and provide the terminal related information for the GIS.

the video network is a centralized control network structure, and the network can be a tree network, a star network, a ring network and the like, but on the basis of the centralized control node, the whole network is controlled by the centralized control node in the network.

As shown in fig. 5, the video network is divided into an access network and a metropolitan network.

The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

2. Video networking packet definition

2.1 Access network packet definition

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 (R)

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.
