A eTerm connection system based on a TCP/IP protocol is characterized in that the eTerm connection system is composed of a eTerm front end, a MCSS server, a host system, an open system, an authentication module and a data transmission module, and the authentication module and the data transmission module are located between the eTerm front end and the MCSS server.
Description
Technical field
The present invention relates to a kind of eTerm connected system and method thereof based on ICP/IP protocol.By this system and method thereof, the eTerm front end can be advantageously connected to boat telecommunications services system based on ICP/IP protocol, uses the various services of boat letter.
Background technology
Before the eTerm product comes into operation, be hopeful to use the terminal of boat telecommunications services, must insert boat letter proprietary network by non-TCP/IP mode by the relevant hardware product.Agent and airline must drop into the communication link that a large amount of hardware and software costs is built boat telecommunications services system, and this situation seriously restricts the boat letter and CAAC's message area advances.Simultaneously, the boat letter also needs to drop into lot of manpower and material resources in order to safeguard that these connect.The technology facility of Internet fast development band rice and cost reduce and can't be applied to rapidly in civil aviaton's information system.At present domestic do not have Related product and technology to address this problem.But exist a large amount of non-boat letter front ends to use the eTerm agreement without permission at present, be connected to the boat communication system, boat communication system safety is reached the stable threat that brings.In this case, boat letter independent research eTerm product system comprises eTerm front end and eTerm background server, and independently defines the eTerm agreement, is provided to the connection standard of boat telecommunications services system.
ETerm connected system and method thereof based on ICP/IP protocol of the present invention is exactly in order to address the above problem.ETerm front end and eTerm agreement can solve the shortcoming of technique scheme, and the eTerm agreement provides the technical specification that is connected to the boat letter based on ICP/IP protocol.The eTerm client provides the realization of eTerm agreement, can be advantageously connected to boat telecommunications services system by the eTerm front end.As long as the user can be connected to Internet, perhaps TCP/IP is connected to the boat communication network jointly, just can use eTerm to use the various services of boat letter.
Summary of the invention
Based on above situation, the invention provides a kind of eTerm connected system and method thereof based on ICP/IP protocol.
ETerm connected system of the present invention is by eTerm front end, MCSS server, host computer system, open system, authentication module, and data transmission module, and described authentication module and data transmission module are between eTerm front end and MCSS server.
Wherein, described authentication module comprises and sends connection request module, Hash authentication module, obtains/responder module and Session Open module etc., wherein obtain/responder module can obtain and reply video identification code.
Described data transmission module comprises instruction transport module, news acquisition module, real user name acquisition module etc.
ETerm method of attachment according to the present invention comprises the steps:
Step 1, eTerm front end will comprise the bag of information such as user name, password and issue the MCSS server, and the MCSS server returns the bag that contains configuration information will for the eTerm front end.
Step 2, eTerm front end will be carried out Session Open operation, and eTerm front end all will shield according to main frame with the MCSS server during this, open screen or reimbursement voucher screen send the fixing bag of form and communicate by letter.
Step 3 is carried out the Hash authentication.
Step 4, transfer instruction, eTerm front end and MCSS server will transmit by packet format according to the rules.
If closed described eTerm front end before connecting, then carry out the step mule that obtains news information; If transmission is the group user name, then to carry out the step of obtaining the real user name; If video identification code is arranged, then to obtain and reply the step of video identification code, and carry out the main frame response steps.

The method of attachment of eTerm connected system of the present invention is described below in conjunction with accompanying drawing.
1 sends connection request
The eTerm front end will comprise the bag of information such as user name, password and issue the MCSS server, and the MCSS server returns the bag that contains configuration information will for the eTerm front end.At first from eTerm front end (the emulation terminal of CA letter independent research, down with) beginning, the first step is for sending connection request.Up (client is to server, down together) packet format regulation is as follows:
The 1st byte is version, and its value is fixed as 0x01; The 2nd byte is the byte number of this bag, is fixed as 162; The the 3rd to 18 byte is user name; The the 19th to 34 byte is password; The the 35th to 98 byte is the Key value, will provide in the table below; The the 99th to 162 byte is reserve bytes, uses after being used for.
The format specification of Key is as follows:
| Content | Bytes range |
