In an embodiment, the present invention provides a data transmission method, please refer to fig. 2, and fig. 2 is a schematic flow chart illustrating the application of the data transmission method in a server. In this embodiment, the data transmission method includes the steps of:
step S10, when receiving IP address updating information which is sent by a gateway and contains the IP address of the gateway, updating the registered IP address of the corresponding gateway according to the IP address updating information;
the IP address update information is update information generated according to the IP address of the gateway after the IP address of the gateway changes. The IP address updating information includes but is not limited to a gateway identifier and an IP address of the gateway, the gateway identifier is used for uniquely determining the gateway, and the IP address of the gateway is the current latest IP address after the gateway is updated in real time. Updating the IP address of the corresponding gateway which is registered according to the IP address updating information, namely updating the IP address of the gateway which is registered in the server through the IP address of the gateway in the IP address updating information to obtain the latest IP address of the gateway which is updated in real time, ensuring that the IP address of the gateway which is registered in the server is valid, automatically initiating a hypertext transfer protocol request by the server through the IP address of the gateway which is registered, waiting for receiving a TCP (transmission control protocol) connection establishment request initiated by the gateway, and establishing a TCP connection with the gateway for data transmission.
Step S20, when detecting that data transmission exists, sending an HTTP GET request to the gateway according to the IP address of the registered gateway;
the HTTP GET request is a request mode in a hypertext transfer protocol, and is a method for acquiring data. And sending an HTTP GET request to the gateway according to the IP address of the registered gateway so as to prepare to establish the TCP connection.
When data transmission is detected to exist, an HTTP GET request is sent to a gateway according to an IP address of a registered gateway, a target address of the data transmission to be transmitted may be obtained first, a target gateway in the data transmission process to be transmitted may be determined according to the target address, a target IP address of the target gateway may be determined from IP addresses of registered gateways of a server, and the HTTP GET request is sent to the target gateway according to the target IP address, which is not limited in this embodiment.
As an alternative implementation, referring to fig. 3, fig. 3 is a schematic flowchart of a data transmission method according to the present invention for sending a hypertext transfer protocol request, where the step S20 sending an HTTP GET request to a registered gateway according to an IP address of the gateway includes:
and step S21, sending an HTTP GET request to the gateway through the TR069 channel and the IP address of the registered gateway.
It should be noted that, in the practical application process, the gateway may be managed through a management platform of the server, the management platform may generally establish a TCP connection with the home gateway, and under a policy configured by an operator BRAS system, the home gateway may occasionally replace its own IP, which may make it difficult for the management platform to actively connect to the home gateway. In this embodiment, the integrated terminal management system in the server is further connected to another terminal such as a gateway through the TR069 channel, and the server sends an HTTP GET request to the gateway through the TR069 channel and the IP address of the registered gateway to prepare for establishing a TCP connection.
Step S30, when receiving a TCP connection establishment request returned by the gateway, establishing a TCP connection with the gateway for data transmission;
and step S40, when the data transmission is detected to be finished, sending a message for closing the TCP connection to the gateway, and disconnecting the TCP connection.
When a TCP connection establishment request returned by the gateway is received, the TCP connection is established with the gateway to carry out data transmission until the data transmission is finished, when the data transmission is detected to be finished, a message for closing the TCP connection is sent to the gateway and the TCP connection is disconnected, so that the TCP connection is established with the gateway under the condition that only the server has data transmission, and when the server does not have data transmission, the TCP connection is disconnected without needing the server and the gateway to always keep a long connection channel for carrying out data transmission, thereby achieving the purposes of reducing the server resources, the network bandwidth and the pressure loaded by a firewall and saving the energy consumption.
As an optional implementation manner, step S30 further includes, before:
receiving an authentication request sent by the gateway;
determining an authentication check result according to the authentication request, and sending the authentication check result to the gateway;
and executing step S30 when the authentication and verification result is that verification is successful.
In an actual application process, in order to ensure the security of the connection between the gateway and the server and improve the security of data transmission, the gateway may send an authentication request to the server, where the authentication request includes authentication information such as a password, a MAC address of the terminal, a serial number of the terminal, and the like. After the server side receives the authentication request, the server side can check according to authentication information in the authentication request to obtain an authentication check result, and when the authentication check result is successful, namely the authentication is passed, the server side indicates that the gateway and the server can be connected, and data transmission between the gateway and the server is safe.
For example, to facilitate understanding that the server actively initiates a gateway connection requirement to the gateway according to the latest IP address registered by the gateway, please refer to fig. 4, where fig. 4 is an interaction diagram illustrating that the server actively initiates a gateway connection requirement to the gateway according to the latest IP address registered by the gateway, and the gateway interacts with the server.
The concrete description is as follows:
1. the server has a data transmission requirement and acquires the latest IP address of the gateway from the stored IP addresses of the registered gateways;
2. informing the ITMS module of the requirement of connecting the gateway;
3. the ITMS module issues an HTTP GET request to a gateway based on a TR069 channel to prepare for establishing connection;
4. the gateway responds to the HTTP request;
5. the gateway initiates a TCP connection request to the server and transmits authentication information (mac, sn, password and the like);
6. the server verifies the authentication information;
7. the server returns authentication passing information to the gateway;
8. the gateway and the server complete the establishment of a TCP connection channel and keep alive through the timing heartbeat message;
9. the server and the gateway transmit data;
10. and after the server finishes the communication requirement of data transmission, actively closing the TCP connection.
As an optional implementation manner, the data transmission method further includes:
and when a heartbeat message request sent by the gateway is received, sending a heartbeat message corresponding to the heartbeat message request to the gateway.
The heartbeat message request may be used to detect whether a normal connection is maintained between the server and the gateway. When a heartbeat message request sent by the gateway is received, a heartbeat message corresponding to the heartbeat message request is sent to the gateway to inform the gateway, and the server and the gateway are normally connected and can continuously transmit data.
In the embodiment, the server updates the registered IP address of the corresponding gateway through the IP address of the gateway in the IP address updating information by receiving the IP address updating information sent by the gateway, so as to obtain the IP address updated by the gateway in real time, when the server has data transmission, the server can actively send an HTTP GET request to the gateway according to the registered IP address of the gateway, and establishes a TCP connection with the gateway for data transmission when receiving the TCP connection establishment request sent by the gateway, and sends a message for closing the TCP connection and disconnects the TCP connection to the gateway when detecting that the data transmission is finished, so that the server establishes the TCP connection with the gateway for data transmission when only the server has the data transmission, and immediately disconnects the TCP connection when the data transmission does not exist, and the server and the gateway are not required to always keep a long connection channel for data transmission, thereby achieving the purposes of reducing the pressure of server resources, network bandwidth and loads and saving energy consumption.
Further, it should be noted that, compared to the server and the gateway always keeping long connection, which results in long-term occupation of server resources and network bandwidth, in this embodiment, connection is actively established only when there is a data transmission communication requirement, and data transmission is immediately disconnected after completion, which can reduce a large number of TCP connections and greatly liberate the performance of the server itself. And because of the characteristics of the wide area network, the gateway connection server may pass through a multi-layer network, the TCP connection establishment request is firstly forwarded to a network firewall or other transfer servers, and when the number of TCP connections is reduced, the network bandwidth and the firewall pressure are also greatly released. In addition, by adding the TR069 channel, the server actively issues a hypertext transfer protocol request such as an HTTP GET request to the gateway through the TR069 channel and the IP address of the gateway, and the gateway sends a TCP connection establishment request to connect the server after receiving the HTTP GET request.
Correspondingly, referring to fig. 5, fig. 5 is a schematic flow chart illustrating the data transmission method of the present invention applied to a gateway. In this embodiment, the data transmission method includes the steps of:
step S50, when the change of the IP address is detected, generating IP address updating information according to the changed IP address;
step S60, the IP address updating information is sent to the server, so that the server can update the registered IP address of the corresponding gateway according to the IP address updating information;
the IP address update information is update information generated according to the IP address of the gateway after the IP address of the gateway changes. The IP address updating information includes but is not limited to a gateway identifier and an IP address of the gateway, the gateway identifier is used for uniquely determining the gateway, and the IP address of the gateway is the current latest IP address after the gateway is updated in real time.
As an optional implementation manner, step S50 is followed by:
sending an HTTP POST request to the server through a TR069 channel and the event that the IP address changes;
and when receiving the information fed back according to the HTTP POST request, executing the step S60.
The HTTP POST request is a request mode in a hypertext transfer protocol, and is a method for sending data.
It should be noted that, in the practical application process, the gateway may be managed through a management platform of the server, the management platform may generally establish a TCP connection with the home gateway, and under a policy configured by an operator BRAS system, the home gateway may occasionally replace its own IP, which may make it difficult for the management platform to actively connect to the home gateway. In this embodiment, through a terminal integrated management system in a server, the terminal integrated management system is further connected to another terminal, such as a gateway, through a TR069 channel, so that when an IP address of the gateway changes, IP address update information is generated according to the IP address after the gateway changes, and further an HTTP POST request is sent to the server through the TR069 channel and an event that the IP address of the gateway changes, wherein after receiving information fed back by the server according to the HTTP POST request, step S60 is executed, that is, IP address update information is sent to the server, so that the server updates the registered IP address of the corresponding gateway according to the IP address update information.
For example, to facilitate understanding of the interaction flow between the server and the gateway after the IP address of the gateway is changed, please refer to fig. 6, and fig. 6 is an interaction diagram illustrating the interaction between the gateway and the server after the IP address of the gateway is changed. The concrete description is as follows:
after detecting that the IP address changes, the gateway sends an HTTP(s) POST request to an ITMS module in the server through a TR069 channel;
the ITMS module responds to HTTP(s) Response;
the gateway sends the latest parameters including the current latest IP address of the gateway;
the ITMS module receives the request and informs the server to update the gateway information;
and finishing the interactive notification.
Step S70, when receiving the HTTP GET request sent by the server, after sending a TCP connection establishment request to the server, establishing a TCP connection with the server for data transmission;
and step S80, when receiving the message of closing the TCP connection sent by the server, disconnecting the TCP connection.
The method comprises the steps of receiving an HTTP GET request sent by a server, namely receiving a TCP connection establishment request signal sent by the server, sending a TCP connection establishment request to the server, then establishing TCP connection with the server to carry out data transmission until receiving a message for closing the TCP connection sent by the server, namely when the server does not have data transmission, disconnecting the TCP connection, and achieving the purposes of reducing the pressure loaded by server resources, network bandwidth and a firewall and saving performance consumption.
As an optional implementation manner, between step S70 and step S80, the data transmission method further includes:
sending a heartbeat message request to the server;
and receiving the heartbeat message fed back by the server to keep TCP connection.
The heartbeat message request may be used to detect whether a normal connection is maintained between the server and the gateway. In the actual application process, signal interference may exist in the connection process between the server and the gateway to cause abnormal connection between the server and the gateway, and by means of sending a heartbeat message request to the server, if a heartbeat message corresponding to the heartbeat message request fed back by the server can be received, it is indicated that the connection between the server and the gateway is normal, so as to keep the TCP connection to perform data transmission.
Optionally, the heartbeat message request may be sent to the server at a fixed time, or at a preset time interval, which is not limited herein.
As an alternative embodiment, in an actual application process, please refer to fig. 7, and fig. 7 is an interaction diagram illustrating that a gateway registers with a server. When the gateway is connected with the server for the first time, the gateway needs to send a registration request to the server, and after the server receives the registration request sent by the gateway, the data verification of the registration request is completed, and a response result is returned. Optionally, the response result may include an agreed period negotiation parameter, where the period negotiation parameter is used to determine the time or time period when the gateway initiates the registration request, that is, the silent period, and the period negotiation parameter may be preset. If the period negotiation parameter can be set as the registration request initiated by the gateway every 6 hours by default, the server can modify the time set by the period negotiation parameter through parameter configuration. If the server determines that the gateway is on-line, the on-line state of the gateway can be updated, a registration result response is sent to the gateway to inform the gateway of successful registration, and the IP address of the registered gateway is stored at the server side.
As an optional implementation manner, after the step S70 sends the TCP connection establishment request to the server, before establishing a TCP connection with the server for data transmission, the method further includes:
sending an authentication request to the server;
receiving an authentication check result fed back by the server;
and when the authentication and verification result is that verification is successful, the step of establishing a TCP connection with the server to perform data transmission after sending a TCP connection establishment request to the server in step S70 is performed.
In an actual application process, in order to ensure the security of the connection between the gateway and the server and improve the security of data transmission, the gateway may send an authentication request to the server, where the authentication request includes authentication information such as a password, a MAC address of the terminal, and a serial number of the terminal. After receiving the authentication request, the server side can check according to authentication information in the authentication request to obtain an authentication check result, and sends the authentication check result to the gateway, so that when the gateway receives the authentication check result and determines that the authentication check result is successful, namely the authentication is passed, the gateway and the server can establish connection, data transmission between the gateway and the server is safe, and after sending a TCP connection establishment request to the server, TCP connection is established with the server to enter a data transmission state.
For example, to facilitate understanding in this embodiment, when receiving a TCP connection establishment request sent by a gateway, a server establishes a TCP connection with the gateway for data transmission, and when detecting that data transmission is completed, sends a message for closing the TCP connection to the gateway and disconnects the TCP connection, so that a specific process that the server establishes the TCP connection with the gateway for data transmission only when there is data transmission in the server, and immediately disconnects the TCP connection when there is no data transmission in the server is realized, please refer to fig. 8, where fig. 8 is an interaction process between the gateway and the server when there is data transmission and there is no data transmission in the server, and the specific description is as follows:
1. the gateway initiates a TCP connection establishment request to a server;
2. the server authenticates the gateway information;
3. returning response information after the authentication is successful;
4. the server checks whether a long connection needs to be maintained according to service needs such as data transmission needs;
5. if no service requirement exists, closing the TCP connection;
6. if the TCP connection needs to be kept, the gateway needs to be informed to send a heartbeat request regularly to maintain the long TCP connection;
7. the gateway sends a heartbeat request at regular time, and if the heartbeat request is sent once in default 10 minutes;
8. the gateway and the server carry out data interactive transmission;
9. the server completes the service requirement and checks whether the TCP long connection needs to be closed;
10. if no service requirement exists, closing the TCP connection;
11. if the heartbeat message needs to be kept, the heartbeat message is kept.
