Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication method and an information providing method, and more particularly to a communication method and an information providing method using a wireless tag.
[0002]
[Prior art]
[Conventional technology 1: Service number and routing number / physical number]
(If the service number is a routing number or physical number)
In the normal basic connection of the telephone network, the service number is a telephone number, and is a routing number / physical number. That is, the exchange in the telephone network selects a route according to the telephone number (routing), and arrives at the intended destination.
[0003]
(If the service number is not a routing number or physical number)
On the other hand, even in a telephone network, in a service such as toll-free, a telephone number as a service number is not a routing number / physical number. This is because the telephone number includes a service identification number such as 0120, so that information as a routing number is insufficient. Therefore, in the case of a service such as toll-free, a service control device called NSP (Network Service Control Point) or SCP (Service Control Point) converts the service number into a routing number / physical number, and reaches the destination. Routing and incoming.
[0004]
The personal number service of the telephone network called UPT (Universal Personal Telecommunication) is to define the "person's" phone wherever the subscriber is and dial the personal number to receive it. Also in the case of this personal number service, the telephone number that is the service number is not a routing number / physical number. Again, a service control device called NSP or SCP converts the service number into a routing number / physical number, routes to the destination, and receives the call.
[0005]
In addition, the definition of “the person” phone is executed by performing a specific registration procedure. Usually, the registration procedure is executed by calling the registration accepting apparatus from the telephone that is to be used as the "person's" telephone and notifying the person who made the telephone call from the telephone after connection.
[0006]
Also, an e-mail address that is a service number in the e-mail service is not a routing number / physical number. By using DNS (Domain Name System), an e-mail address is converted into an IP address which is a routing number / physical number, and the e-mail is routed and delivered to an e-mail destination.
[0007]
In addition, in the e-mail, the following device is devised in order to perform the conversion efficiently. First, an e-mail address has a structure of “name @ host name (domain name)”, and a DNS server (IP address) corresponding to the service number “name @ host name (domain name)” in the DNS server determined by the host name. ) Conversion.
[0008]
The host name (domain name) is host-a. company-x. co. A hierarchical description such as jp is made, and a DNS that actually performs conversion is also hierarchically started from an initial point called a root, a DNS server of a jp domain, and a co domain in the DNS server The DNS server can be searched in order, and finally the DNS having the conversion information can be reached.
[0009]
[Conventional technology 2: Location notification service]
As a location notification service, (1) a service in which a third party obtains location information by specifying the location of the terminal by GPS or the like, and the terminal notifies the specified location to the network or sends it to the other party during communication, ▲ 2 ▼ A service that identifies the location of a specific mobile terminal (person who has a specific mobile terminal) is known to the location information user by identifying the radio base station under which the mobile phone company uses the radio base station. It has been.
[0010]
[Problems to be solved by the invention]
However, in recent years, apart from the conventional technique 1 and the conventional technique 2, a device called a wireless tag or RFID (Radio Frequency-IDentification) (hereinafter simply referred to as “wireless tag”) has been realized and is going to spread. Yes. The wireless tag has a specific ID, and the advanced tag has a memory, an encryption circuit, an authentication circuit, and the like. An inexpensive one has only a specific ID. Wireless communication on the scale of several tens of centimeters to several tens of meters is possible. If there is a wireless tag detector in the wireless communication area, the wireless tag detector reads the wireless tag ID and memory contents.
[0011]
This wireless tag is attached to many people and things, and may be used for article management or the like instead of a barcode (low-cost wireless tag (tens of yen)). In addition, a slightly larger and more advanced wireless tag can be used for preschoolers, kindergarteners, and elderly people to check their actions so that they do not leave the controlled area.
[0012]
Therefore, in view of such circumstances, the present invention makes it easy for a caller to easily communicate with a person having a wireless tag, and for a service provider to easily provide information on an object equipped with a wireless tag or a person having a wireless tag. It aims at providing the information provision method which can be provided to.

[0059]
Hereinafter, the communication method according to the first embodiment will be described in detail.
[0060]
This communication method is roughly divided into two. The first is that any one of the wireless tag detectors 110 to 113 indicates that a person having the wireless tag of FIG. 6 has entered the conference room 101 of FIG. 2 and is seated in any one of the chairs 103 to 106. Is a step (hereinafter referred to as “first step”) until the detection result is registered in the wireless tag detector management database 203, and the second is someone who is a subscriber phone 211 or mobile phone. Steps until a communication request is made to the person having the wireless tag of FIG. 6 via the telephone (or PDA) 208 or the computer 209 and communication according to the request is executed (hereinafter referred to as “second step”). It is said.)
[0061]
(First step according to the first embodiment)
Assume that the owner of the wireless tag 601 in FIG. 6 (hereinafter referred to as “the called party”) enters the conference room 101 and sits on the chair 104. The wireless tag detector 111 provided in the chair 104 detects the wireless tag 601 attached to the called party.
[0062]
As information of the wireless tag 601 detected by the wireless tag detector 111, in the case of only the wireless tag ID of the wireless tag 601 (in this case, the wireless tag is referred to as “low price wireless tag”), in addition to the wireless tag ID. Service number yamada @ company-x. co. jp may also be included (the wireless tag in this case is referred to as an “advanced wireless tag”).
[0063]
Then, the wireless tag detector 111 notifies the wireless tag detector management apparatus 203 of “detection” of the detected information via the network 202.
[0064]
Upon receiving the “detection” notification from the wireless tag detector 111, the wireless tag detector management device 203 extracts the wireless tag ID from this notification and writes it to the wireless tag database device 205 via the network 202 in order to write information to be described later. to access.
[0065]
The wireless tag detector management device 203 that has accessed the wireless tag database device 205 searches for the wireless tag detector management information in FIG. 7 and manages the wireless tag detector 111 using the wireless tag ID (“1234468233”) as a key. A management database device is detected. In addition, the wireless tag detector management device 203 that has accessed the wireless tag database device 205 searches for the wireless tag detector information of the wireless tag database device 205 using the wireless tag ID (“1234468233”) as a key, and the corresponding record. Reference is made to FIG.
[0066]
Then, the wireless tag detector management device 203 includes the wireless tag detector number 111 that detects the wireless tag 601 in the wireless tag detector number column and the building management database device column in the corresponding record in FIG. Write the building management database device name (building management database device 204).
[0067]
Thus, the first step is completed.
[0068]
(Second step according to the first embodiment)
For example, it is assumed that a PDA user (hereinafter referred to as “caller”) on the telephone network / mobile phone network 210 of FIG. 1 wants to communicate with the callee of FIG. At this time, the caller is not aware of what terminal the callee is near.
[0069]
However, the caller knows that the service number of the callee is “yamada@company-x.co.jp”.
[0070]
The caller accesses the service number connection device 207 via the network 202 using the IP telephone client software for service number connection service. Specifically, the service number “yamada@company-x.co.jp” of the callee is entered in the destination column of the connection request signal on the IP telephone client software for service number connection service, and the connection for which this input has been made The request signal is put into an IP packet destined for the service number connection device 207 and sent to the service number connection device 207 via the network 202.
[0071]
The service number connection device 207 that has received this IP packet identifies that it is a connection request signal, and reads the service number of the callee specified as the destination. The service number connection device 207 that has read the service number accesses the service number wireless tag ID conversion database device 206 via the network 202 and reads the wireless tag ID corresponding to this service number.
[0072]
The service number connection device 207 that has read the wireless tag ID accesses the wireless tag database device 205 via the network 202, searches the wireless tag detector information of FIG. 4 using the read wireless tag ID as a key, The wireless tag detector number 111 and the building management database device name (building management database device 204) are read out.
[0073]
The service number connection device 207 that has read the wireless tag detector number 111 and the building management database device name (building management database device 204) accesses the building management database device 204, and uses the wireless tag detector number 111 as a key for the wireless tag. The telephone number (or IP address) of the room where the detector is installed is read (in the case of only the telephone number information, not the IP address information, the connecting device 207 confirms that the telephone number is the IP telephone number. And the IP telephone number / IP address converter in the network 202 converts the telephone number into an IP address.
[0074]
Then, the service number connection device 207 replaces the service number “yamada@company-x.co.jp” input in the destination column of the connection request signal with the telephone number “03-3399-1234”. Is sent to an IP packet with the IP address corresponding to the telephone number “03-3399-1234” as the destination IP address, and the IP packet is delivered to the IP telephone 107 via the network 202.
[0075]
As described above, IP phone 107 receives the connection request signal transmitted from the caller via mobile phone 209.
[0076]
Although the telephone 107 is an IP telephone in the first embodiment, the present invention is not limited to an IP telephone. Therefore, in the present invention, the telephone 107 may be a subscriber telephone. In this case, the service number connection device 207 uses the destination IP address of the IP packet as the IP address of the gateway device between the network 202 and the telephone network 211 (not shown) to which the subscriber telephone is connected. The data is transmitted to the gateway device via the network 202.
[0077]
When the connection request signal is included in the received IP packet, the gateway device reads the telephone number “03-3399-1234” from the destination column of the connection request signal, and the telephone number “03-3399-1234”. The connection request signal is transmitted to the subscriber telephone via the telephone network 211 (not shown).
[0078]
The service number “yamada@company-x.co.jp” in the first embodiment includes English characters, but the service number according to the present invention is not limited to English characters.
Therefore, in the present invention, the service number can be composed only of numerals.
[0079]
In this case, for example, the above-mentioned callee is given two service numbers (a service number with numbers only for access from a subscriber phone or mobile phone, and a service number with easy-to-remember alphanumeric characters, Japanese or Kanji). Can be assigned.
[0080]
In addition, if a service number composed of a numeric identifier and a number that is consistent with the telephone / mobile phone number system is given, the service number composed of a numeric identifier and a number can be changed using the service number connection device 207, etc. The first embodiment can be applied as it is by converting the service number into
[0081]
In the first embodiment, for simplicity of explanation, the service number wireless tag ID conversion database device 206 is one. However, in the present invention, a plurality of service number wireless tag ID conversion database devices 206 are provided. It can also be provided. In this case, the service number wireless tag ID conversion database device 206 can have a structure corresponding to the structure of the service number.
[0082]
Specifically, the service number wireless tag ID conversion database device 206 can be hierarchized that is used in Internet DNS or the like.
[0083]
For example, in a method of inserting a break (delimiter) of a hierarchy “.” Into a name consisting of an arbitrary character string, the service number is “yamada.company-x.co.jp”.
[0084]
In this case, as shown in FIG. 8, a database called “root” has an address of a database such as “jp” under the umbrella, and a database called “jp” has an address of a database such as “co” under the umbrella, A structure that specifies the data accommodation database hierarchically is defined.
[0085]
As a result, the number of service subscribers according to the present invention is enormous, and in the first embodiment, it is difficult for the service number wireless tag ID conversion database device 206 to search for the corresponding wireless tag ID. Even in the situation, the service number wireless tag ID conversion database device 206 searches corresponding wireless tag IDs in a distributed and efficient manner.
[0086]
That is, in the example of “yamada.company-x.co.jp”, co and company-x are sequentially traced from the root. For example, when the service number is small, xxx. co. It may contain all service numbers in the format jp. Alternatively, since only the next company-x may be another database, in that case, in that database, information to that effect (subordinate database (here, database called company-x)) Address information for access).
[0087]
Furthermore, when the lowest part of this hierarchy is treated specially and only the part of the part is represented by @, the format is “yamada@company-x.co.jp”. Furthermore, a format (for example, personal: yamada@company-x.co.jp) using an identifier (for example, personal) for indicating a service number is also conceivable.
[0088]
According to the present invention, since any of the above hierarchies can be realized, the scale can be increased.
[0089]
Furthermore, as will be described later, even in the example of extracting the RFID tag detector number from the building name (from the building number) in the building management database device, the building number is hierarchized, and the database structure is prepared accordingly to prepare the database structure. Search is possible.
[0090]
In the case of a service number of only numbers that can be transmitted from a telephone / mobile phone, hierarchization can be achieved in the same manner as described above. Specifically, (communication) business operator number, business operator branch number, etc. are defined, service number (example: 050)-business operator number (example: 124)-business operator branch number (example: 7)-personal correspondence department (Example: 2783). The hierarchy of the database is configured in the form of each company under the root and each business branch under the company.
[0091]
In the above description, an example in which a simple incoming service is realized with a service number has been described. However, in the first embodiment, for example, a destination telephone or a called party (called party) is placed in a conference room. If it is, it can be combined with incoming condition control such as not receiving a call, making a voice mail connection, or receiving in the work room.
[0092]
[Second Embodiment: Application to Anycast Communication]
In the first embodiment described above, a mode in which communication to the called party is communicated with the service number is described. However, according to the second embodiment of the present invention, the service number "Company X Sales Department" is used. It is also possible to apply to a form in which a plurality of persons in the sales department of company X are designated and communication is performed with one or all of them. For example, it is a form of communicating with one person in the sales department of company X in the xxx building.
[0093]
The first step in the second embodiment is that the number of wireless tag numbers corresponding to the service number in FIG. 5 is plural, and the registration in the first communication step is performed for each wireless tag. Although the first step in the first embodiment is different, the other steps are the same.
[0094]
The second step in the second embodiment is as follows.
[0095]
For example, assume that a PDA user (ie, “caller”) on the telephone network / mobile phone network 210 of FIG. 1 wants to communicate with one of the sales departments of company X in the xxx building. At this time, the caller is not aware of what kind of terminal the person in the sales department of Company X is near.
[0096]
However, the caller knows that the service number of the sales department of company X is “sales@company-x.co.jp”.
[0097]
The caller accesses the service number connection device 207 via the network 202 using the IP telephone client software for service number connection service. More specifically, an anycast connection request signal on the IP telephone client software for service number connection service (anycast means that if there are a plurality of destination candidates, it communicates with one of them) X in the destination column Enter the service number “sales@company-x.co.jp” of the company sales department, enter “I am in xxx building” in the condition area, and send the anycast connection request signal with this input to the service number connection device It is put into an IP packet with 207 as the destination, and sent to the service number connection device 207 via the network 202.
[0098]
The service number connection apparatus 207 that has received this IP packet identifies that it is an anycsst connection request signal, and reads the service number and conditions of the sales department of company X designated as the destination. The service number connection device 207 that has read the service number accesses the service number wireless tag ID conversion database device 206 via the network 202 and reads a plurality of wireless tag IDs corresponding to the service number.
[0099]
The service number connection device 207 that has read a plurality of RFID tags accesses the RFID tag database device 205 via the network 202, and searches the RFID tag detector information of FIG. 4 using the read RFID tag ID as a key. Then, each RFID tag detector number and the building management database device name are read out.
