CN100367736C - Method and apparatus for connecting a workstation to a wide area network - Google Patents

Now,, will be connected to

2 such as the workstation1 of personal computer (PC) such as modulator-demodulator in order to be connected to specific

3 referring to Fig. 1.Specific

3 can be any one particular network that special services can be provided to following client, and described client subscribes their service.

The invention provides as lower device, described device solves is not comprising mutual and the problem during via

2 visit given wide-

3 of Any user.This just means and might come h.323-configured

2 and can obtain state information from

3 via

2 with minimum user intervention under the situation that is independent of the residing pattern of

2 operations.

When the local area network (LAN) set up between workstation1 and the

2, provide an in house software program to workstation1, described in house software program only is used under beginning and/or layoutprocedure.The first dedicated fixed IP address is provided for

2, attached workstation1 uses described IP address at the purpose of above-mentioned foundation, and the 2nd IP address (only can be identical with described fixed address under route pattern) is provided for

2, described the 2nd IP address is used to set up and the communicating by letter of given wide-area net 3.Thereby after aforesaid operations, a beginning sequence just has been established, and this begins process is inactive under the proper communication business.Disturb if certain can take place after a while, then workstation1 just restarts identical beginning process.

Sometimes, the keeper of

3 upgrades the communication feature of network.Subsequently, wide area network can send to the reservation workstation1 with this updated information with described network.Then, workstation1 is collected the NEW BEGINNING program from

3.

Workstation1 restarts process at the beginning, to use new being provided with

2 is installed.

Software program in the workstation1 can be upgraded to the software in the

2, and can also obtain state information from gateway 2.Also can provide such process automatically, and carry out any operation without the user of workstation1.

In the middle of second embodiment as shown in Figure 2, can with the more than one work station in the middle of the Local Area Network (1.1,1.2 ... 1.N) be connected on the gateway 2.Provide actual software program to the work station of each connection, the work station of each connection all has the device of the local area network (LAN) that is used to be mounted to

2 like this.Finish after the fitting operation, and each work station (1.1,1.2 ... 1.N) just can both communicate by letter with specific

3.

2 according to the present invention has the fixedly private ip address of appointment, even not on same subnet,

2 also usually responds described IP address.Utilize the method, can use generic browser, and connect in

2 and be configured or the like.

1.IP number is generally from the Dynamic Host Configuration Protocol server on the ISP end.If gateway 1 (modulator-demodulator) is not configured, then just can't carry out work, and workstation1 (PC) can't obtain the IP address to the connection of given wide-area net 3.If have implicit IP connectivity, then can utilize fixing special I P number to connect described gateway in any case, and then it is configured again, so that the connection of given wide-

3 is able to work.

2. the user needn't change any setting in order to interrelate with

2 in the workstation1.If workstation1 does not have on subnet and gateway or the same fixed ip address of ISP end, it can also be worked so.

3. the user needn't remember the IP number of

2.

4. for the gateway of all this type, the fixedly special I P number that is used for getting in

2 all is identical usually.This makes and becomes easier for gateway provides configuration and administrator tool.

1. one kind is connected to the method for the given wide-area net (3) that this work station (1) will be assigned to work station by a gateway (2), it is characterized in that:

A fixed IP addresses is provided for this gateway (2);

This work station (1,1.1,1.2 ... insert a program 1.N), this program is used for setting is provided to this gateway (2), and described setting is suitable for communicating by letter with described given wide-area net (3).

2. the method for claim 1 is characterized in that:

In the time of in this setting being provided to this gateway (2), just between this work station (1) and this given wide-area net (3), provide the proper communication business automatically.

3. method as claimed in claim 1 or 2 is characterized in that:

With more than one work station (1.1,1.2 ... 1.N) be connected to this gateway (2), each work station all is assigned to a Local Area Network;

As long as one of described work station is provided to described setting in this gateway (2), just automatically each work station (1.1,1.2 ... 1.N) and between this given wide-area net (3) provide the proper communication business.

4. one kind is used for work station (1) is connected to the device of this work station (1) with the given wide-area net (3) that is assigned to, it is characterized in that:

Gateway (2) has a fixed ip address, is used to make this gateway (2) to be connected to this work station (1);

The program that provides in this work station (1), when this work station (1) had been addressed to described fixed ip address in this gateway (2), described program was used for providing the setting that is suitable for given wide-area net (3) at gateway (2).

5. device as claimed in claim 4 is characterized in that:

Be used for after described gateway (2) provides described setting described work station (1,1.1,1.2 ... 1.N) and the device of proper communication business is provided between the described given wide-area net (3).

6. as claim 4 or 5 described devices, it is characterized in that:

Be connected to described gateway (2) more than one work station (1,1.1,1.2 ... 1.N), each work station all is assigned to a Local Area Network;

Be used for when when described gateway (2) provides described the setting automatically each work station (1,1.1,1.2 ... 1.N) and the device of proper communication business is provided between the described given wide-area net (3).

7. device as claimed in claim 6 is characterized in that:

Described gateway has the identical fixedly special I P number that is used for described local area network communication.

8. as claim 4 or 5 described devices, it is characterized in that:

For upgrading, described given wide-area net (3) is suitable for sending to described work station the program of a renewal; Then, described work station utilizes the program of described renewal to be reset at described setting in the described gateway (2).
