DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an embodiment of the present invention. In the figure, reference numeral 1 denotes the Internet, and a plurality of Internet service providers individually build provider networks PN1 to PNm and Internet protocol addresses (hereinafter, referred to as IPs). The network comprises an IP address management server 3 of an IP address management center that manages these networks, and a backbone network 4 interconnecting these networks.

In the provider networks PN1 to PNm, a mail server 6 and a WWW (World)
Wide Web) server 7 and DNS (Domain)
A name system (server) 8 is connected, and an access point 9 composed of a dial-up router is provided. The access point 9 is connected to an information processing terminal 11 such as a personal computer used in a general home via a public line 10. Is connected to another router 12 via the leased line 13 and the corporate network 1
4 are connected.

The information terminal 11 is connected to a display 21, a keyboard 22, and a mouse 23, and is connected to a global positioning system (GPS).
GPS satellite 24 that constitutes an oning system)
GPS which receives the radio wave from and outputs the latitude and longitude information
A satellite radio wave receiving device 25 is provided, and the latitude and longitude information output from the GPS satellite radio wave receiving device 25 is read as its own installation position information, and the provider network P is read.
When connecting to Ni (i = 1, 2,..., M), the installation location information is transmitted, and the corresponding IP address is dynamically allocated, or the area registered in the IP address management center in advance. Select an IP address that has uniqueness.

The corporate network 14 has a backbone LAN 15, and mail servers 17a and W are connected to the backbone LAN 15 via routers 16a to 16c.
The WW server 17b and the DNS server 17c are connected, and an in-house LAN 19 is connected via a router 18. A server 20 and a number of information processing terminals 21 are connected to the in-house LAN 19.

The IP address management center is provided, for example, in a resident registration section of a ward, municipal government, and assigns an IP address as a global address corresponding to the installation position of the information processing terminal when registering as a resident. It is managed by the server 3. here,
The assignment of the IP address is performed based on, for example, a postal code. The postal code is composed of a total of 7 digits of "123"-"4567", and the upper two digits of the first three digits correspond to prefectures. For example, in Tokyo, "1"
“0” to “20” are “21” to “25” in Kanagawa Prefecture.
However, in Ishikawa prefecture, "92" is assigned, and in Toyama prefecture, "93" is assigned, and the remaining one digit is assigned to the ward, municipal,
The last four digits indicate the area within the city. Therefore, it is possible to specify a detailed postal administrative division in a prefecture, a ward, a municipal or the like from the postal code, and by assigning this postal code as a part of the IP address, the postal information in which the information processing apparatus is arranged by the IP address itself. It can represent an administrative division.

By the way, since the current IP address is version 4 and is composed of a 32-bit numerical value, a 7-digit numerical value is required to incorporate the postal code into the IP address as described above. , 24 bits are required in terms of the number of bits.
Because it is difficult to include all of the digits in the postal code,
7-bit postal information representing two digits representing a prefecture is set as a predetermined bit.

However, in version 6 which is the next-generation IP address standard currently being studied, the IP address is expanded from 32 bits to 128 bits, and
It is considered to be a continuous address space in which the concept of classification used in the current version 4 is removed. Therefore, by assigning a postal code to 24 bits starting from a predetermined bit of the 128 bits constituting the IP address, the IP address includes information indicating the installation position of the information processing apparatus. By reading the postal code information of the predetermined bits, the installation position of the information processing apparatus can be specified.

When a new IP address is to be assigned, an IP address management center is arranged in the resident registration section of the municipalities. A global address is issued by inserting a postal code corresponding to the address of the resident registration into a predetermined bit of the IP address. Specifically, the IP address management server 3 manages an IP address that requires pre-assigned management and an IP address that manages the IP address.
An address management table is provided, and the IP address management server 3 executes the IP address assignment processing shown in FIG.

In this IP address assignment processing, first, in step S1, an IP address registration screen is displayed, and then the process proceeds to step S2, where a name and address, a telephone number, and a contact address such as an e-mail address are input. If the name and address have not been entered, the process waits until these are entered. If the name, address and contact information have been entered, the process proceeds to step S3 to search for the postal code based on the address. Referring to the table, the postal code corresponding to the address is extracted, and then the process proceeds to step S4 to extract the extracted postal code.
Based on 24-bit zip code information representing a zip code of a digit, an IP address management table for managing an IP address and user information in association with each zip code is searched, and an IP address for which an assignment destination is not registered is searched. Then, the process proceeds to step S5, where the address, name, telephone number, or e-mail address to be assigned is registered at the extracted IP address position in the IP address management table, and then, the process proceeds to step S6 to be determined. After printing out the IP address or storing the IP address in a portable storage medium such as a flexible disk, the process returns to step S1.

In the processing of FIG. 2, the processing of steps S1 and S2 corresponds to the installation position information setting means, and the processing of steps S3 to S6 corresponds to the communication address allocating means. The printed IP address or a storage medium storing the IP address is handed to the resident registrant, and the resident registrant registers the IP address in a predetermined storage area such as a hard disk of the information processing apparatus 11 at home. By contracting with an Internet service provider, it becomes possible to access a WWW server on the Internet via an access point of the provider network PNi.

On the other hand, in the case where a resident who has already been registered as a resident installs the information processing apparatus 11, the information processing apparatus 11 receives a radio wave from the GPS satellite 24 and receives the latitude as shown in FIG. In the case where a GPS satellite radio wave receiving device 25 that outputs longitude information is provided, the latitude and longitude information output from the GPS satellite radio wave receiving device 25 is taken in as current position information, and the public line 10 and the provider network PNi are connected. By accessing the IP address management server 3 via the Internet and transmitting the current location information,
The address server 3 assigns an IP address including the postal code information at a predetermined bit position as a global address.

That is, the information processing apparatus 11 executes the IP address acquisition processing of FIG. 3 by activating predetermined Internet service provider connection application software. This IP address acquisition processing
First, in step S11, the GPS satellite radio wave receiving device 25
Is read as the current position information, and then the process proceeds to step S12 where the public line 1
0, access the IP address server 3 via the provider network PNi to transmit the IP address request command and the current position information and the user information such as the address, name, contact information, etc., and then proceed to step S13 to It is determined whether or not the IP address has been received. If the IP address has not been received, the process waits until the IP address has been received.
After the address is stored as a global address in a predetermined storage area such as a hard disk or a semiconductor memory, the process ends.

On the other hand, the IP address management server 3 executes an IP address assignment process shown in FIG. In this IP address assigning process, first, in step S21, it is determined whether an IP address request command, current position information and user information have been received from the information processing apparatus 11, and the IP address request command, current position information and usage information are determined. When the user information is not received, the process waits until it is received, and when the IP address request command, the current location information and the user information are received, the process proceeds to step S22, where the postal code in the corresponding area is determined based on the current location information. Then, the process proceeds to step S23, where the IP address and the user information are managed in association with each other based on the postal code.
With reference to the P address management table, a vacant IP address that includes postal code information in a predetermined bit position and is extracted is then extracted. Then, the process proceeds to step S24, where the user information is stored in the extracted IP address position in the IP address management table. Is written, the process proceeds to step S25, the IP address is transmitted to the information processing apparatus 11 via the provider network PNi, and the process returns to step S21.

In the processing of FIGS. 3 and 4, the processing of steps S11 and S12 and the processing of step S21 correspond to the installation position information setting means, and are performed in steps S22 to S25.
Corresponds to the communication address allocating means. When the IP address including the postal code information is stored in the predetermined storage area of the information processing device 11 at the predetermined bit position as the global address, the Internet can be accessed.

Therefore, for example, a WWW server function, a mail server function, DNS
Assuming that, for example, weather forecast information for each region is stored in the database server 17 having a function, for example, the information processing apparatus 1 is connected via the provider network PN1.
When accessing the database server 17 from 1,
By obtaining the IP address of the accessed information processing apparatus 11, by extracting the postal code information arranged at a specific bit of this IP address, the area where the accessing information processing apparatus is installed is determined. The weather forecast of the corresponding area can be immediately transmitted to the accessed information processing terminal.

For this reason, the user can immediately obtain the weather forecast at the current position, so that the access time to the database server 17 can be reduced, and the access time at the user side can be reduced at the database server 17 side. By shortening, more user access can be answered. On the other hand, when it is desired to search the WWW server existing in a specific area from the information processing apparatus 11, when a desired search condition name is specified as a search condition and a search is performed in a prefecture unit,
By specifying the upper two digits of the postal code information set in a predetermined bit of the IP address, it becomes possible to search for a WWW server having a desired search condition name among WWW servers existing in the specified prefecture. Further, when it is desired to narrow down to the ward, municipal, and municipal areas, it is possible to narrow down to a desired area by designating the upper three digits of the postal code information or the upper four digits or more as a search condition.

In the first embodiment, the case where the IP address including the postal code is assigned as the global address has been described. However, the present invention is not limited to this. After dialing up from the information processing apparatus 11 of the user, after performing user authentication, the IP address including the postal code corresponding to the position where the access point 9 is located in a predetermined bit is dynamically determined, and the information processing apparatus 11 of the user is dialed up. 11, the IP address may be stored in a predetermined storage area such as a hard disk of the information processing apparatus 11 of the user, and the dial-up IP connection may be completed.

Also in this case, the user selects an access point close to the installation position of his / her information processing apparatus 11 from the relation of the call charge. The location can be substituted, and the same operation and effect as in the first embodiment can be obtained. In addition, since the IP address is not a global address but a dynamic address, it is possible for another person to search for the IP address. There are advantages that are not possible.

Further, in the first embodiment, the case where the current position is measured using the global positioning system has been described. However, the present invention is not limited to this. The current position can be specified from the electric field strength of the user, or any other current position measuring means can be disliked. Further, in the first embodiment, the case where the postal code is searched from the current position information has been described. However, the present invention is not limited to this, and it is possible to specify the current position directly from the latitude / longitude information. Instead, a unique IP address may be generated.

Further, in the first embodiment, the case where the IP address is generated by the IP address management server 3 and is notified to the information processing apparatus 11 has been described. However, the present invention is not limited to this. An IP address for each postal code may be assigned to the service provider in advance, and the IP address may be assigned by the Internet provider.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, when the information processing apparatus is not an installation type such as a desktop, but is a node-type personal computer or another mobile device, the installation position is specified by carrying and carrying the information processing apparatus.

Therefore, by setting the base station 32 as the installation position of the mobile communication device 31, the current position of the mobile communication device 31 can be ascertained, and the base station 32 acquires the IP address from the mobile communication device 31. When a predetermined command indicating that the user wants to do so is received, an IP address including a postal code corresponding to the current position of the own station in a predetermined bit, which is previously allocated from the IP address management server 3, is dynamically allocated. Have been.

Therefore, when starting communication with the base station 32, the mobile communication device 31 executes the IP address acquisition processing shown in FIG. In this IP address acquisition processing, first, in step S31, it is determined whether or not a communication connection with the base station 32 has been made. If the communication connection has not been made, the process waits until a communication connection is made. If it has been performed, the process proceeds to step S32 and the base station 3
2, an IP address request command is transmitted, and then the process proceeds to step S33 to determine whether an IP address has been received from the base station 32. If an IP address has not been received, this is received. If an IP address has been received, the process proceeds to step S34, where the received IP address is stored in a predetermined storage area such as a hard disk or a semiconductor memory, and the process is terminated. Thereafter, the user accesses a desired homepage on the Internet 1 using the IP address stored in the predetermined storage area.

On the other hand, the base station executes the IP address assignment processing shown in FIG. This IP address assignment processing
First, in step S41, it is determined whether or not an IP address request command has been received from the mobile communication device 31, and if it has not been received, the process jumps to step S45 described later. The telephone number is not registered from the IP address assignable range including the postal code corresponding to the current position of the own station in the predetermined bit managed by the own station with reference to the IP address management table. A free IP address is searched, and this free IP address is
Determined as a dynamic IP address to be assigned to 1, and
The process proceeds to step S43 to register the telephone number of the mobile communication device 31 at the determined IP address position in the IP address management table, and then proceeds to step S44 to transmit the determined dynamic IP address to the mobile communication device 31. Then, the process proceeds to step S45.

In step S45, the mobile communication device 3
It is determined whether there is a communication device whose connection state has been disconnected. If there is no mobile communication device 31 whose connection state has been disconnected, the process returns to step S41 and the mobile communication device whose connection state has been disconnected. If there is, the process proceeds to step S46, where the IP address management table is searched based on the telephone number of the disconnected mobile communication device 31, and the telephone number of the IP address in which the telephone number is registered Is deleted and returned to the empty state, and then the step S4 is performed.
Return to 1.

In the processing of FIGS. 6 and 7, the current position is specified by communicating with the base station 32 in the processing of steps S31 and S32 and the processing of step S41. The processing of steps S42 to S45 corresponds to the communication address allocating means. Next, the operation of the second embodiment will be described.
