Even in such a case, the customer can receive information from a plurality of notification requesters with a single portable terminal.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a wireless notification system according to an embodiment of the present invention.
A wireless notification system using a public wireless system includes a wireless notification device including a gateway device 3 and a database device 4 included in the gateway device 3, a wireless base station 7, and a public wireless network 8 between the wireless base station 7 and the portable terminal 9. Consists of. In the figure, a notification request server 1 of a service provider that provides various services to a customer is connected to a gateway device 3 of a wireless notification service provider by way of a network 2 such as the Internet. The gateway device 3 and the wireless base station 7 are connected by a wired network 6 via a router 5, and the gateway device 3 and the customer's portable terminal 9 are closest to the portable terminal 9 so that they can wirelessly communicate with each other. Communication is performed via the wireless base station 7. Although there are a plurality of notification request servers 1 and portable terminals 9, only one is shown here.

  The database device 4 is a computer device such as a database server, for example, and is a service provider requesting notification of information related to a service requested by a customer, that is, a notification requester for identifying a requester of a wireless notification service. ID (notification requester identification), a set of service ID (notification destination identification) that identifies a customer to be notified in the service provider, and a public address of the portable terminal 9 used in the public wireless network 8 Information for associating with the terminal ID is held.

  The gateway device 3 is a computer device such as a server, for example, and the terminal of the portable terminal 9 from the database device 4 using the notification requester ID and service ID set in the notification message received from the notification request server 1 as keys. The ID is read, and the read terminal ID is set as the destination of the notification message and output.

  The portable terminal 9 is a computer device such as a mobile phone terminal in a public mobile phone network or a wireless terminal in a wide area ubiquitous network. Based on the received notification message, the portable terminal 9 outputs information notified to an output unit such as a display or a lamp provided in the portable terminal 9.

FIG. 2 is a diagram illustrating a setting example of address management data held by the database device 4.
The address management data includes a plurality of entry data in which the notification requester ID and service ID are associated with the terminal ID of the portable terminal 9. Here, the IP address of the notification request server 1 is used as the notification requester ID, but an electronic certificate, FQDN (Fully Qualified Domain Name), or the like may be used. The service ID uses the address system of the e-mail address, but other address systems may be used. The terminal ID is a public address used in the public wireless network 8. When the public wireless network 8 is a mobile phone network, the terminal ID is a mobile phone number, and when the public wireless network 8 is a wide area ubiquitous network. The terminal ID in the wide area ubiquitous network can be used.

Next, the operation procedure of the wireless notification system shown in FIG. 1 will be described.
The terminal ID of the portable terminal 9 shown in FIG. 1 is “12345678”, and the IP address of the service provider notification request server 1 is “10.10.10.10”. At this time, the wireless notification service provider registers the address management data shown in FIG. Further, the service provider registers the service ID “okyakusama @ hogehoge” of the portable terminal 9 in the notification request server 1. The terminal ID is not informed to the service provider.

  When the service provider's notification request server 1 notifies information related to the service requested by the customer, the service ID “okyakusama @ hogehoge” that is managed by the service provider and specifies the notification destination is set. The notification message having the destination information and the source information set with its own IP address “10.10.10.10” is transmitted.

  Upon receipt of the notification message transmitted from the notification request server 1, the gateway device 3 receives the service ID “okyakusama @ hogehoge” from the destination information of the notification message, and the IP address “10.10. 10.10 "is extracted. The gateway device 3 transmits a search request message for requesting to search for a terminal ID to the database device 4. In the search request message, the service ID extracted from the notification message and the IP address of the notification request server 1 are set.

  When the database device 4 receives the search request from the gateway device 3, the database device 4 stores the service ID “okyakusama @ hogehoge” in the search request and the IP address “10.10.10.10” of the notification request server 1 as keys. The terminal ID “12345678” is read out from the address management data (FIG. 2) to be sent back to the gateway device 3.

  When the gateway device 3 receives the terminal ID “12345678” from the database device 4, the gateway device 3 sets the terminal ID to the destination information in the notification message received from the notification request server 1 of the service provider, and transmits it to the portable terminal 9. To do. Thereby, the portable terminal 9 receives the notification message from the wireless base station 7 to which the mobile terminal 9 currently belongs via the public wireless network 8, and outputs to the output means based on the information indicating the notification content read from the notification message. Do. By confirming the output of the portable terminal 9, the customer can know the notification content from the service provider, for example, information related to the service.

  Note that the database device 4 registers the IP address of the notification request server 1 in the search request in the case where the IP address of the notification request server 1 stored in advance is not registered in the address management data. If not, an error is returned to the gateway device 3. When the gateway device 3 receives an error from the database device 4, the gateway device 3 discards the notification message.

Next, an application example of the above-described public wireless system will be described.
FIG. 3 is a diagram showing an example applied to a cleaning service. Here, information regarding cleaning is exchanged between a cleaning company as a service provider and a customer.
That is, the customer receives the portable terminal 9 also serving as a voucher when the product requested for cleaning is delivered to the cleaning company. In order to notify the customer of the cleaning status, the cleaning company transmits a notification message in which information indicating the cleaning status is set to the gateway device 3 from the notification request server 1 held by itself. The gateway device 3 transmits the address information of the portable terminal 9 in the public wireless network 8 set in the destination information of the notification message, and the portable terminal 9 turns on the lamp corresponding to the cleaning status indicated by the received notification message. Let After the lamp indicating the completion of cleaning is turned on, the customer takes the portable terminal 9 to the cleaning company and exchanges it for a product that has been cleaned.

FIG. 4 is a diagram showing an example applied to a failure repair service. Here, information on failure repair is exchanged between the customer and the customer of the failure repair as a service provider.
That is, the customer receives the portable terminal 9 that also serves as a voucher when the product for which the repair is requested is delivered to the contractor for the repair. The failure repair contractor sends a notification message in which information indicating the failure repair status is set to the gateway device 3 from the notification request server 1 held by the failure repair contractor to notify the customer of the failure repair status. The gateway device 3 transmits the address information of the portable terminal 9 in the public wireless network 8 set in the destination information of the notification message, and the portable terminal 9 turns on the lamp corresponding to the repair status indicated by the received notification message. Let After the lamp indicating the completion of repair is turned on, the customer takes the portable terminal 9 to the contractor for repair and exchanges it for a repair product.

  3 and 4, the portable terminal 9 may be a mobile phone owned by a customer, a wireless terminal in a wide area ubiquitous network, or the like.

According to the above, the gateway device 3 of the wireless notification service provider provides the customer used in the public wireless network from the combination of the service provider ID and the ID that identifies the customer of the notification destination in the service provider. It is possible to acquire the original address information of the portable terminal and notify the customer's portable terminal of the information requested by the service provider. Therefore, the customer can receive only information regarding his / her desired service wherever he / she is while keeping his / her original address secret from the service provider. In addition, in the unlikely event that customer service information held by a service provider is leaked, it is possible to prevent the customer's original address from leaking and to correctly convert information from third parties. Since this is not possible, information that is not intended for the purpose is not sent to the customer.
Also, since service IDs are different for different service providers even for the same customer, a wireless notification service is provided to a plurality of service providers of the same or different industries using a single gateway device 3 can do. Even in such a case, the customer can receive information from a plurality of service providers with a single portable terminal.

  The notification request server 1, the gateway device 3, the database device 4, and the portable terminal 9 have a computer system therein. The operation processes of the notification request server 1, the gateway device 3, the database device 4, and the portable terminal 9 described above are stored in a computer-readable recording medium in the form of a program, and the computer system reads this program. The above processing is performed by executing the above. The computer system here includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case is also used to hold a program for a certain period of time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The wide area ubiquitous network that can be applied to the wireless notification system will be described below. As for wide area ubiquitous network, Hiroshi Saito, Masahiro Umehira, Masahiro Morikura, “Discussion for Wide Area Ubiquitous Network Infrastructure”, IEICE Transactions 2005/11 Vol. J88-B No. 11 etc.

  Wide-area ubiquitous networks are broadly divided into two types: mobile terminal services that are assumed to carry mobile phones and other terminals, and embedded environment services that are based on an environment where sensors and other objects are attached to people and objects. Separated. The former is based on mobile phones that are mature in terms of population penetration, but it is also assumed that mobile phones will be used as gateways to accommodate ultra-small sensors, and in reality these boundaries are not clear. .

FIG. 5 is a diagram illustrating a configuration of a currently assumed ubiquitous network.
From the viewpoint of wide-area network infrastructure, the terminal accommodation form is divided into two, direct accommodation (direct acquisition) and accommodation via a gateway, and the latter is the form of the network (described as “local network”) beyond the gateway. Thus, it is divided into gateway accommodation and gateway network accommodation. The terminal accommodation of the gateway is a form in which the terminal in the local network communicates only with the gateway, and the network termination of the gateway is a form in which the terminal in the local network communicates with other terminals in the local network.

In the case of direct acquisition, the terminal needs an end-to-end communication function and a unique address on the network. In the case of gateway accommodation, the terminal only needs to be able to communicate with only the gateway (gateway terminal accommodation) or with the gateway and other terminals in the local network (gateway network accommodation). Therefore, it is easy to apply a local address or a special protocol suitable for the local network. The difference between network accommodation and terminal accommodation depends on the protocol used in the local network. In order to accommodate the network, it is necessary to use a multi-hop such as Bluetooth or ZigBee or introduce a routing protocol. Although it is easier to accommodate terminals, when a wireless link is used, network accommodation is necessary to physically cover a wide area with one local network.
At present, the mobile phone network is the most powerful network infrastructure for direct acquisition. The network infrastructure in the case of accommodating a gateway is assumed to be an Internet access network and an Internet / IP network or a mobile phone network.

  In the wide area ubiquitous network, compared to the currently assumed ubiquitous network described above, the “scalability” regarding the number of terminals, the “wide area” capable of covering a physically wide range, the “mobility management” corresponding to the mobile terminal, the terminal Because of the large number of terminals, low-capacity terminals with low functionality and limited computing capacity and memory capacity are assumed from the viewpoint of total terminal cost, so "low-capacity terminal support" that can accommodate them, many terminals Since it is connected to the network, it is necessary to provide "economics" that reduce network costs. Therefore, the wide area ubiquitous network is realized by a complex network set as shown in FIG.

Next, a specific implementation example of the wide area ubiquitous network system will be described.
FIG. 7 shows a configuration example of a wide area ubiquitous network system. In the figure, the wide area ubiquitous network system holds a wireless terminal 101, gateway nodes (hereinafter referred to as GW nodes) 102 to 105 capable of wireless communication with the wireless terminal 101, and position information of the wireless terminal 101. A mobile communication network having a location registration database 109 and an Internet 110 to which personal computers (hereinafter referred to as PCs) 111 and 112 as terminals to which messages from the wireless terminal 101 are connected are connected to an Internet gateway. (Hereinafter, referred to as the Internet GW).

In addition, the network system includes relay nodes 106 and 107 and a registration management system 108 that holds the address of the PC 101 as a terminal that is a transmission destination determined in advance for each wireless terminal 101.
Communication between the wireless terminal 101 and the PC 111 or PC 112 as a terminal is roughly performed as follows.
When transmitting a message from the wireless terminal 101 to the PC 111 or the PC 112, when any of the GW nodes 102 to 105 receives a wireless frame from the wireless terminal 101, the GW nodes 102 to 105 access the registration management system 108 for each wireless terminal. The terminal address of the message destination is specified, and the message is transmitted to the PC 111 or the PC 112 which is the specified destination terminal via the Internet GW 113.

  Further, when a message is transmitted from the PC 111 or the PC 112 to the wireless terminal 101, the Internet GW 113 accesses the location registration database 109, acquires location information from the ID of the wireless terminal 101, and applies the corresponding location information from the acquired location information. The gateway node transfers the message to the wireless terminal.

  The wireless terminal 101 can perform wireless communication with the GW nodes 102 to 105. The GW nodes 102 to 105, the registration management system 108, and the location registration database 109 are connected to each other via the relay nodes 106 and 107, and can communicate with each other. The wireless terminal 101, the GW nodes 102 to 105, the registration management system 108, the location registration database 109, and the relay nodes 106 and 107 constitute a mobile communication network.

The mobile communication network is also connected to the Internet 110 via the Internet GW 113 and can communicate with personal computers (PCs) 111 and 112 connected to the Internet 110.
Here, the GW nodes 102 to 105, the relay nodes 106 and 107, and the Internet GW 113 all have IP addresses and can communicate with the PCs 111 and 112 via the Internet 110.

The wireless terminal 101 is mounted on a moving object, and position registration is required when moving.
Each of the GW nodes 102 to 105 wirelessly broadcasts the paging area number, and the wireless terminal 101 receives a number different from the paging area number held by itself and recognizes the change of the area in which it is located. When the service area changes, the wireless terminal 101 (1) updates the paging area number held by itself, and (2) the paging area number (service area) that the user has visited via the GW node / relay node. Number) is notified to the location registration database 109. The location registration database 109 stores a set of {wireless terminal ID, presence area number} shown in FIG. 8 as location information.

  The wireless terminal 101 can receive a message from a predetermined PC 111 and an arbitrary PC 112. The PCs 111 and 112 transmit the communication message to the Internet GW 113 via the Internet 110 in a TCP / IP packet with the originating address as its own address and the destination address as the Internet GW 113 address.

  At the beginning of the communication message, the own address is entered as the source address, the ID of the wireless terminal 101 is entered as the destination address, and the message to be transmitted is entered thereafter. The Internet GW 113 that has received the packet extracts the message and recognizes that the communication is for the wireless terminal 101. Then, the location registration database 109 is accessed, and the located area number is acquired from the wireless terminal ID. The internet GW 113 obtains the address of the GW node in which the wireless terminal 101 is located by drawing the address table of the GW node corresponding to the area in which it is held as shown in FIG.

Then, the extracted message is transmitted in a TCP / IP packet in which the source address is the own address and the destination address is the address of the GW node in which the wireless terminal 101 is located. The GW node that has received the TCP / IP packet extracts a message from the packet and recognizes that the communication is for the wireless terminal 101. Then, the same message is transmitted to the wireless terminal 101 through the wireless channel.
When the communication source is only the PC 111 determined in advance, the source address area of the message can be deleted.

  For example, when the Internet GW 113 has the function of the gateway device 3, the PCs 111 and 112 are the notification request server 1, the Internet 110 is the network 2, the relay nodes 106 and 107 are the router 5, and the GW nodes 102 to 105 are As the base station 7, the terminal 101 can be considered as a portable terminal 9.
