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.
The video networking is an important milestone of network development, is a real-time network, can realize high-definition video real-time transmission, and pushes a plurality of Internet applications to high-definition video, and high definition is face-to-face.
The video networking adopts a real-time high-definition video exchange technology, can integrate required services such as dozens of services of video, voice, pictures, characters, communication, data and the like on a system platform on a network platform, such as high-definition video conference, video monitoring, intelligent monitoring analysis, emergency command, digital broadcast television, delayed television, network teaching, live broadcast, VOD on demand, television mail, personal Video Recorder (PVR), intranet (self-office) channels, intelligent video broadcast control, information distribution and the like, and realizes high-definition quality video broadcast through a television or a computer.
The nouns are explained as follows:
DHCP: the Dynamic Host Configuration Protocol is a network Protocol of a local area network. The method is characterized in that a server controls a segment of lP address range, and a client can automatically obtain the lP address and the subnet mask distributed by the server when logging in the server.
GGSN: the Gateway GPRS Support Node, the Gateway GPRS Support Node and the boundary between the GPRS network and the external network are internally responsible for the transmission of the Gn network and externally are an Internet router. The BGGSN (Border GGSN) is responsible for connecting Gn networks between different operators to implement inter-network roaming. The GGSN is connected to other GGSNs and SGSNs via a GPRS backbone network based on IP protocol.
The establishment of a network transmission is established on a fixed IP address + port, and the end EndPoint is used as the identifier of a network channel link. Generally, there is one and only one EndPoint when one network card establishes a connection. According to the networking mode of the core network, the base station and the terminal, the IP address of the terminal device may or may not change during the networking process, and specifically, the IP address changes mainly in the following cases 2 and 3:
1. the IP address cannot be changed when the base station is switched in the same area;
the 4G ensures seamless switching between the base stations, namely the process of switching the base stations, as long as the network is not disconnected (4G link, not data switch) in the switching process, the random access is not initiated again, and the original IP address of the IP address is obtained;
2. the access is reinitiated, and the IP address is changed;
the access is reinitiated, the IP address can be changed, and after the IP address is allocated to the core network, the GGSN core network automatically allocates according to the DHCP protocol; the re-initiation of the access process, which may be a power-on restart or an airplane mode switch, is a process from no signal to a signal.
3. From one area to another, the IP address may change;
the IP address allocation is allocated by a regional GGSN core network, for example, the terminal equipment is currently accessed to the communication network of the A region in the A region, the outlet IP address is also the communication network of the A region, but when the terminal equipment moves from the A region to the B region, the access network is changed into the communication network of the B region, and the IP address connected with the terminal equipment is definitely changed;
an embodiment of the present invention mainly addresses the situation in item 3, where an embodiment of the present invention provides a data transmission method, which is used for a server to update termination point information corresponding to a network card channel identifier according to the network card channel identifier sent by a terminal device. The execution main body of the embodiment is a data transmission device and is arranged on the server.

In the embodiment of the present invention, one network card may be installed on the terminal device, or multiple network cards may be installed on the terminal device, and specifically, the network card may be set according to actual needs, which is not specifically limited in the embodiment of the present invention.
The terminal device establishes a network card channel with the server through the network card, and sends a detection data packet to the server through the established network card channel, wherein the data packet carries a network card channel identifier and first end point information, and the first end point information is EndPoint and comprises an IP address and a port number.
S102, obtaining second destination node information corresponding to the target network card channel identification according to a pre-established destination node information and network card channel identification corresponding table;
specifically, a correspondence table of destination node information and network card channel identifiers is pre-established on the server, and communication is performed with the terminal device according to the destination node information in the correspondence table, and in order to ensure that no packet loss occurs in the downlink process, after receiving a detection data packet sent by the terminal device, the server determines second destination node information corresponding to a destination network card channel identifier in the detection data packet according to the destination network card channel identifier in the detection data packet.

And S104, carrying out data transmission with the terminal equipment according to the first terminal node information.
Specifically, after updating the destination node information corresponding to the target network card channel identifier, the server performs data transmission with the terminal device according to the updated first destination node information, that is, the IP address and the port number, thereby avoiding the problem of adding a new link due to the change of the IP address in the prior art.
