1) terminal device

User end:

Uses the Xiamen mulberry glory science and technology development limited company the GPRS connection module, uses the PCMICA\ string mouth and the computer is connected, completes the user system the constitution, user's computer run user's system software and application software.

Bureau end:

Uses line and connection which the motion company provides.

Along with the technical unceasing development, portable PC\ grasps the type computer (Pocket PC) the function to be formidable day after day, specially grasps the type computer (Pocket PC) the volume unceasingly to simplify, says Pocket regarding enterprise's staffs
PC carries and the operation very is all convenient.

User system:

The user uses PC machine, uses PCMCIA the \ string mouth and this terminal is connected, realization system correspondence.

The Xiamen mulberry glory science and technology development limited company provides GPRS Modem (pcmcia card type) (the RS232 connection) the general operating environment and the formidable handling ability enables the terminal device with table model Modem to be able through to the GPRS network and the backstage application service support, rapidly completes the data inquiry and the handling of traffic.

Using service

Mainly is composed by four software:

Front end software:

Front end the software movement in the terminal, supports the local service data the inquiry and service business processes; Simultaneously manages the wireless communication network, completes the digit dialing, hangs breaks and the condition monitor; Processes regarding business requested and confirmed, realizes the reliable transmission control, the guarantee and the bureau end cooperation.

Outside net service software:

Outside net service software completes with the front end software safe authentication and adds the decipher, outside the coordination the net inquiry database completes the data inquiry request processing and the reply; In processing the net server produces outside data synchronization order maintenance net inquiry database; Serves software for in net to provide the transmission with front end software which penetration physics isolates in, enables the handling of traffic request to be allowed safely effectively to arrive the net and to carry on processing.

In net service software:

In net service software completes with the outside net service software isolation transmission, and adds the decipher with the front end software safe authentication, has business to front end to process the request to carry on the explanation, the execution, depends upon the database suitably to match level software, various services database synchronization to outside net inquiry service software.

The bureau end database suitably matches level software:

The bureau end database suitably matches level software to exist polysome to is the heterogeneous database platform service database provides the abstract connection in, supports net service software to complete business processing and data synchronization.

Used in the GPRS network wireless data transmission to pass through more than several years of constructions, China moves the GPRS net to realize the coastal area comprehensive cover and the mountainous area area place city cover, and 5.17 officially provided the service in 2002 to the user. The high quality network which the GPRS service high speed data transmission, "forever on-line", "the current capacity costs" and "the nation roams" the characteristic as well as China moves, has met the different level customer need, also has laid the solid foundation for the development profession application.

3. special lines APN transmission mode

According to the enterprise to the network security special request, the Xiamen mulberry glory science and technology limited company has designed based on the GPRS network data transmission plan, has used the many kinds of security measure, mainly includes:

Turns on the motion company GPRS network through a 2M special line, both sides interconnects between the router to use the private IP address to carry on the macrozonality connection, interconnects between the router in GGSN and the motion company to use the GRE tunnel.

For customer assignment special-purpose APN, the average consumer does not have to apply for this APN. Uses in GPRS the special net SIM card only to clear this special-purpose APN, the limit uses other APN.

The customer may from construct a set of RADIUS server and the DHCP server, GGSN provides to the RADIUS server with the head of household calls the number, picks the user to be called the authentication way which the number and the user account number unifies; The user assigns the enterprise interior after the authentication by the DHCP server the static IP address.

End-to-end encryption: Between the mobile termination and the server platform uses the end-to-end encryption, avoids the information in the entire transmission process possible divulging.

Both sides use the firewall to carry on the isolation, and carries on the IP address and the port on the firewall filters.

4. services flows

The GPRS special net system terminal accesses the net registers the server platform the flow is:

1) the user sends out GPRS to register the request, requested including by the motion company is special net APN which the GPRS special net system specially assigns;

2) acts according to requested APN, SGSN sends out the inquiry request to the DNS server, found with enterprise server platform connection GGSN, and the user requested gives GGSN through the GTP tunnel seal;

3) GGSN the user authentication information (including handset number, user account number, password and so on) delivers through the special line to Radius carries on the authentication;

4) the Radius authentication server saw authentication information and so on hand serial number, the confirmation is the request which the validated user sends in, to DHCP server request assignment user address;

5) the Radius authentication through after, carries the user address by Radius to the GGSN transmission the confirmation information;

6) the user obtained the IP address, may carry the data packet, carries on the visit to the GPRS special net system information inquiry and the handling of traffic platform.

Fourth, motion fees standard and equipment expense

1st, this service including opens a bank account to spend, to install the debugging expense, the GPRS special net working cost as well as uses GPRS to have the current capacity fees.

1) the special net opens a bank account to spend as well as installs the debugging to spend (special net application)

Opens a bank account the expense: 1,000 Yuan

Installs the debugging expense: 500 Yuan

2) the server carries the GPRS special net working cost (special net application) 1,000 Yuan/month or 10,000 Yuan/years, does not limit to the terminal number;

3) terminal GPRS current capacity fees (terminal application)

2nd, the equipment needs terminal router (customer voluntarily to choose) about 5,000 Yuan, each spot equipment GPRS wireless MODEM, probably between 2000-2800 Yuan.
