Detailed Description
The invention relates to an EOC terminal management method based on port forwarding.A channel is established between an EOC local side and a newly added EOC terminal based on a port forwarding technology, so that the communication between the EOC local side and the newly added EOC terminal is realized; in the technical scheme of the invention, the mode of managing the newly added EOC terminal by the EOC local side is not limited to the existing MME protocol any more, and flexible management can be realized by using various modes including but not limited to Web, Telnet, JSONO and the like; in the embodiment, the implementation is performed based on the Web technology; which comprises the following steps.
S1: the newly added EOC terminal is connected to an EOC local side in a wired mode, such as an axial cable;
in this embodiment, an embedded Linux operating system is adopted in the EOC local side device, and the receiving and forwarding of the data packet of the EOC local side are all realized by a standard Linux protocol stack; the EOC local side equipment and the terminal equipment are both arranged in an EOC network based on the HomePlug AV technical scheme.
S2: the Web end of the EOC local side detects a newly added EOC terminal, and determines whether the terminal type is EOC terminal equipment with a wireless function based on the prior art;
if the EOC terminal equipment with the wireless function is not the EOC terminal equipment with the wireless function, the wireless terminal management is not carried out, and the management process is stopped;
otherwise, establishing a transmission channel between the EOC local side and the newly added EOC terminal based on the process through a port forwarding technology in the EOC local side;
in specific implementation, the port forwarding technology uses the existing technology, such as technology called "ported", and any tool or technology capable of implementing the function of redirecting Transmission Control Protocol (TCP) connection may be used.
S3: the EOC local side sets a terminal serial number for the newly added EOC terminal; once the terminal serial number is set, the terminal serial number is bound with the newly added EOC terminal, and even if the newly added EOC terminal is off-line, the EOC local side also retains the corresponding terminal serial number; when the newly added EOC terminal is connected to the EOC local side again, the same terminal serial number is used; each accessed EOC terminal has a terminal serial number thereof, so that all accessed EOC terminals are effectively managed by the system.
S4: the EOC local side calculates and generates an IP address and a port number of a newly added EOC terminal based on the board card serial number and the terminal serial number of the EOC local side;
during concrete implementation, the following steps are provided: the board card serial number cbatindex of the EOC local side is 0, and the terminal serial number cnuendex set for the newly added EOC terminal in the EOC local side is 2, then: the generated IP address of the terminal is xxx.xxx.0.2.
S5: and the EOC local side encrypts the IP address and the port number based on the transmission channel and sends the IP address and the port number to the newly added EOC terminal through the extension message type.
S6: and the newly added EOC terminal receives the message sent by the local side equipment, decrypts the message to obtain an IP address and a port number, and starts the WAN function after setting the terminal.
S7: after receiving the IP address and the port number, the newly added EOC terminal sends a response message to an EOC local side; the EOC local side can access the website of the newly added EOC terminal according to the IP address and the port number, so that the newly added EOC terminal is managed;
when the specific implementation is realized, after receiving a response message sent by a newly-added EOC terminal, the EOC local side jumps to a corresponding address, and the address format is as follows: and (3) the http:// < local side address > < port number allocated to the terminal >, and the user is guided to input the user name and the password of the newly-added EOC terminal, so that the webpage side of the newly-added EOC terminal can be directly accessed, and the management operation of the newly-added EOC terminal is carried out.
S8: after the EOC local side finishes managing the newly added EOC terminal, closing the related process of the transmission channel, and finishing the management process aiming at the newly added EOC terminal; and closing the related process after the completion, reducing the workload of the EOC local side equipment, and ensuring that the EOC local side equipment works at the optimal efficiency.
The technical scheme of the invention is an EOC terminal management method based on port forwarding technology, local side equipment configures corresponding IP addresses for WAN ports of EOC wireless terminal equipment through a port forwarding tool, thereby realizing the management of the EOC wireless terminal on a software level and simplifying a management structure; according to the technical scheme, hardware equipment does not need to be replaced, the management requirement of new wireless terminal equipment can be met on a software level, the manual maintenance work is greatly simplified, and the management cost is reduced.
