Description

  The present invention relates to a communication method, more specifically, a plurality of terminals on the Internet or an arbitrary intranet, and a server on the Internet that manages an access method to the terminal, and is a source terminal that is one of the terminals However, when accessing a partner terminal that is another terminal registered in the address book database owned by the user, depending on the information in the address book database, the partner terminal may be accessed. The present invention relates to a communication method for specifying the access method.

  In the Internet, an IP connection is used. In this case, an IP address is used to identify a computer or the like. Since this is an enumeration of numbers, it is convenient for processing by a computer, but it is difficult for humans to remember.

  In view of this, a method has been devised in which a domain name represents a network or a computer and performs mutual conversion with an IP address. This is DNS. For example, the IP address is represented as 203.22.1155.243, while the domain name is www. saver. ne. It is expressed as jp.

  As a matter of course, in this method, the user of the transmission source needs to know the individual destination IP address or domain name in advance when accessing the destination terminal. However, as mentioned above, since it is common to remember the domain name rather than the IP address, for example, if the other party's domain name is changed, it is impossible to connect to the other party who wants to access There is a problem of becoming.

  The present invention has been made in order to solve such problems in the prior art. For example, a communication method that enables easy access to a partner even when the partner's domain name changes occurs. The issue is to provide.

The invention according to claim 1 for solving the above problem comprises a plurality of terminals on the Internet or an arbitrary intranet, and a server on the Internet that manages an access method to the terminal. When one of the sender terminals accesses a partner terminal that is another terminal registered in its own address book database, it cannot access the partner terminal using the information in the address book database. ,

Preferably, further, wherein the server when the destination terminal is offline, the steps from the previous SL originating terminal to allow receiving the message file of the addressed destination terminal, before Symbol server, from said source terminal When receiving a message file addressed to the destination terminal, when the destination terminal is online, notifying the destination terminal to that effect; and receiving the notification, the destination terminal Receiving the message file from a server.

  The present invention is as described above, and provides a communication system that can easily identify and communicate with an access method to a partner terminal by making an inquiry to the server even when the partner terminal data changes. There is a possible effect.

  Embodiments of the present invention will be described with reference to the accompanying drawings. First, the system configuration of the communication method according to the present invention will be described with reference to FIG. In the following description, WWW is a hypertext format distributed information system. In the WWW, a computer storing information is a network side SRS (Status Renewal Server), and a terminal capable of searching for information is a terminal side SRS. The Internet is a network environment that spreads around the world by connecting networks to each other. An intranet is a computer network within an organization such as a company that uses Internet technology and infrastructure. It is a system that aims to build and share information.

  The network side SRS 1 is connected to the source terminal 3, the destination terminal 4, and the proxy WWW server 5 via the network 2, and constitutes a communication system according to the present invention.

  The network side SRS 1 responds to a search access related to the terminal data of the destination terminal 4 from the source terminal 3, and the IP address 9 or the telephone number 11 that is data related to the destination terminal 4 searched using the address book database 7. Information is transmitted to the source terminal 3. The address book database 7 stores terminal data such as an IP address, a domain name, and a telephone number related to each individual terminal, and details thereof will be described later with reference to FIG. The IP address is a numerical sequence corresponding to the address of a computer connected to the Internet. The address book database 7 may be independent from the terminal side SRS 6.

  The transmission source terminal 3 has a terminal side SRS 6 that makes a telephone call to the destination terminal 4, and the terminal side SRS 6 also has an address book database 7. The terminal-side SRS 6 can make a call to the telephone number of the partner terminal 4 and connect to the partner terminal 4 via the common carrier 8 (see FIG. 3). The terminal-side SRS 6 connects the source terminal 3 to the network 2. The terminal-side SRS 6 accesses the network-side SRS 1 or the terminal-side SRS 6 of another terminal, and the other party in the address book database 7 sent from the network-side SRS 1 or the terminal-side SRS 6 of another terminal. Information on the terminal 4 is received.

  In addition, when the destination terminal 4 is offline, the message is transmitted and received. When the caller terminal 3 is in an online state, it is registered as “online” with respect to the network-side SRS 1, and when it is in an offline state, “ "Offline" is registered, and online / offline registration is performed. Further, the network side SRS 1 is accessed to confirm the online / offline of the destination terminal 4.

  The source terminal 3 and the destination terminal 4 have the same configuration, have a telephone function, and can make and receive calls from the terminal. The source terminal 3 and the destination terminal 4 can access the network side SRS 1 via the network 2 and can search the data stored in the address book database 7.

  The source terminal 3 and the destination terminal 4 are connected to each other via a common carrier 8 and a communication line. Therefore, when making a call to the destination terminal 4, by operating the source terminal 3 and calling the destination terminal 4 via the common carrier 8, the other party can be called.

  The proxy WWW server 5 accepts messages or data and manages transmission / reception. The proxy WWW server 5 can store messages, data, and the like sent from the caller terminal 3 and send the sent data to the partner terminal 4 via the network 2. Here, the data refers to data that can be transferred from the source terminal 3 to a certain content, and the destination terminal 4 can convert the data and open the original content.

  Here, the data structure of the address book database 7 will be described with reference to FIG. In the address book database 7, the IP address 9, the domain name 10, the telephone number 11, the user name 12, the location information 13, the intranet information 14, the last date information 15 to the network side SRS1, the system property 16, and the information from other terminals The access log 17, user group information 18, shared file information 19, and incoming call permission information 20 are registered as one record.

  The registration of the IP address 9 is, for example, “202.32.xxx.xxx”, the registration of the domain name 10 is, for example, “satoh.saver.ne.jp”, and the registration of the telephone number 11 is For example, “03-xxxx-xxxx” is registered, and the user name is registered, for example, “Ichiro Sato”.

  Also, the location information 13 is “Tokyo”, the intranet information 14 is “LAN”, the last update information 15 is “10.6.001: 20” 16, the name of the OS and the like are registered. Further, the access log 17 is “1”, the group information 18 is “company”, the shared file information 19 is “Lv. Are respectively registered as “Lv.1”.

  These data are centralized and managed by each terminal-side SRS 6. Therefore, when the terminal data of “Ichiro Sato” is changed, it is corrected each time, and the latest data is always registered.

  Next, the flow of the communication method according to the present invention will be described with reference to FIG. When the user of the transmission source wants to access the destination terminal 4, first, the transmission source terminal 3 is connected to the network side SRS 1 via the network 2. The transmission source terminal 3 selects a partner to be accessed. For example, by selecting “Ichiro Sato”, the input of the other party's selection information is completed (step S1).

  On the other hand, the network side SRS 1 performs a database search from the selection information. That is, the network side SRS 1 searches the address book database 7 having the data structure as shown in FIG. 2 (step S 2). When the information of the corresponding partner is hit, the network side SRS 1 transmits the search result information to the transmission source terminal 3 (step S 3). That is, network side SRS1 transmits the other party's IP address 9 or telephone number 11 to the transmission origin terminal 3, and the transmission origin terminal 3 receives information (step S4). That is, the source terminal 3 receives the information of the IP address 9 or the telephone number 11 transmitted from the network side SRS 1.

  Next, the caller terminal 3 checks the connection status of the other party. That is, the transmission source terminal 3 sends a request for online / offline confirmation of the counterpart terminal 4 to the network side SRS 1 via the network 2 using the terminal side SRS 6. The network side SRS 1 confirms the online / offline state of the counterpart terminal 4 in response to the confirmation request from the source terminal 3 (step S5).

  When the partner terminal 4 is confirmed online (S6), the caller terminal 3 makes a call, and when connected to the partner terminal 4, communication is possible. When the counterpart terminal 4 is offline, the network-side SRS 1 searches for an online third terminal that registers the access method to the counterpart terminal 4 in the address book database (S7).

  When the third terminal is present, the network side SRS 1 notifies the caller terminal 3 that access to the counterpart terminal 4 is possible via the third terminal (S8). If the presence of the third terminal cannot be confirmed, the source terminal 3 is notified that the means for accessing the counterpart terminal 4 cannot be grasped at present (S9).

  In addition, when the destination terminal 4 is offline, the user of the source terminal 3 can also perform message registration. That is, the user registers the content to be transmitted and stores it as a message file, and the terminal side SRS 6 of the transmission source terminal 3 transmits the message file to the proxy WWW server 5. That is, the terminal side SRS 6 transmits the stored message file to the proxy WWW server 5 using the IP address 9 or the telephone number 11 of the partner terminal 4 already received from the network side SRS 1, and the proxy WWW server 5 Accepts a message.

  Next, proxy WWW server 5 informs partner terminal 4 of the incoming message. On the other hand, when the destination terminal 4 is connected to the network 2 and knows that a message has arrived from the proxy WWW server 5, it can see the content if the content of the message is text and listen if it is a voice. Message transmission is possible.

  Next, a situation where the use of the communication method according to the present invention is assumed will be described with reference to FIGS. First, an example of specifying a communication partner by accessing via the common carrier 8 will be described (see FIG. 3). This case is a complete peer-to-peer access, and the source terminal 3 (terminal A) is charged. The terminal-side SRS 6 of the transmission source terminal 3 grasps the existence of the counterpart terminal 4 (terminal B).

  Next, an example of specifying a communication partner by accessing via the Internet will be described (see FIG. 4). This case is 1: n type access. By using the network-side SRS 1, the IP address 9 of the online counterpart terminal 4 (terminal A to terminal F) can be recognized, and all are charged.

  Next, an example in which a communication partner is specified by accessing via Bluetooth will be described (see FIG. 5). This case is a 1: n access at a short distance. The terminal SRS 6 of the transmission source terminal 3 (terminal A) can grasp the existence of the other party and can broadcast.

  Next, an example in which a communication partner is specified by the combined access in the cases of FIGS. 4 and 5 will be described (see FIG. 6). In this case, the source terminal 3 (terminal A) accesses the counterpart terminal 4 (terminal B) using the terminal C as a gateway. Access from terminal B to terminal A is also possible.

  Although the operation of the communication method according to the present invention has been generally described above, a specific embodiment will be described with reference to FIGS. First, an example of referring to an address book database owned by the counterpart terminal 4 will be described as a first embodiment (see FIG. 7).

  In this case, the source terminal 3 (terminal A) selects or manually inputs the telephone number of the destination terminal 4 (terminal B) from its own address book database, and makes a call to the destination terminal 4. The counterpart terminal 4 wakes up when an incoming call is received.

  The counterpart terminal 4 publishes a record that may be disclosed to the source terminal 3. The source terminal 3 downloads the necessary part and stores it in its own address book database. Alternatively, jump from the referenced address book database link to another terminal.

  When the partner terminal 4 is out of service area or not turned on, there is no means for accessing the partner terminal 4, and the partner terminal 4 knows that it has received a call from the sender terminal 3. Since the call cannot be made, the caller terminal 3 automatically calls at regular intervals and waits for connection establishment.

  Next, another example of referring to an address book database owned by the counterpart terminal 4 will be described as a second embodiment (see FIG. 8). In this case, the source terminal 3 (terminal A) goes to the partner side terminal 4 (terminal B) from the network side SRS1, but when the destination terminal 4 is offline, the destination terminal 4 is connected to the network side SRS1. Commit messages when you are online.

  When the destination terminal 4 comes online, it receives a message from the source terminal 3 from the network side SRS 1. At that time, if the source terminal 3 is online, the network side SRS 1 informs that the destination terminal 4 is online, and the source terminal 3 accesses the destination terminal 4.

  If the transmission source terminal 3 is offline, the data requested by the transmission source terminal 3 is stored in the proxy WWW server 5. When the transmission source terminal 3 comes online, the network side SRS 1 informs the proxy WWW server 5 that the requested data has arrived, and the transmission source terminal 3 refers to the data on the proxy www server 5.

  Next, another example of referring to the address book database owned by the counterpart terminal 4 will be described as a third embodiment (see FIG. 9). This case is a case where the terminal C in the online state is in a communicable state with the terminal B by Bluetooth and the terminal-side SRS, but the terminal B is offline.

  The terminal C in the online state always synchronizes the address book database of its own terminal SRS and the address book database of the network SRS1. The source terminal 3 (terminal A) goes to the network side SRS 1 by referring to the destination terminal 4 (terminal B) and knows that it can be accessed via the terminal C. Terminal C is not necessarily in the same group as terminal A or terminal B. The source terminal 3 refers to the address book database of the destination terminal 4 using the terminal C as a gateway.

  Next, as a fourth embodiment, an example of downloading a file owned by the counterpart terminal 4 will be described (see FIG. 10). In this case, the telephone number of the destination terminal 4 (terminal B) is selected or manually entered from the address book database of the source terminal 3 (terminal A), and the destination terminal 4 is dialed.

  The counterpart terminal 4 wakes up when an incoming call is received. The counterpart terminal 4 publishes a file that may be disclosed to the source terminal 3. The transmission source terminal 3 downloads a necessary file. When the destination terminal 4 is out of service area or not turned on, the source terminal 3 automatically dials at regular intervals to establish a connection. It is only after the connection to the destination terminal 4 is established that the destination terminal 4 knows what file it has.

  Next, another example of downloading a file owned by the counterpart terminal 4 will be described as a fifth embodiment (see FIG. 11). In this case, when the destination terminal 4 comes online, the terminal-side SRS and the network-side SRS1 store and synchronize the history of when and what files have been downloaded and what files have been deleted.

  The transmission source terminal 3 (terminal A) can inquire of the network side SRS 1 in advance what kind of file the destination terminal 4 (terminal B) has. If it is a necessary file, the source terminal 3 pulls the destination terminal 4 from the network side SRS1, but when the destination terminal 4 is offline, the destination terminal 4 comes online to the network side SRS1. Commit a message when

  When the destination terminal 4 comes online, it receives a message from the source terminal 3 from the network side SRS 1. At that time, if the source terminal 3 is online, the network side SRS 1 informs that the destination terminal 4 is online, and the source terminal 3 accesses the destination terminal 4.

  If the source terminal 3 is offline, the destination terminal 4 stores the data requested by the source terminal 3 in the proxy WWW server 5. When the transmission source terminal 3 comes online again, the network side SRS 1 informs the proxy WWW server 5 that the requested data has arrived, and the transmission source terminal 3 refers to the data on the proxy WWW server.

  Next, another example of downloading a file owned by the counterpart terminal 4 will be described as a sixth embodiment (see FIG. 12). In this case, the source terminal 3 (terminal A) is searching for a file of a certain keyword and searches the network side SRS1.

  If the owner of the found file has made it public as a shared file, a direct connection is established, or access is made by the proxy WWW server 5 or the Bluetooth gateway and downloaded. In this case, the best market database is realized by having as much additional information as possible such as frequency of use.

  As described above, in the present invention, the IP address 9 or the telephone number 11 of the partner is searched using the registered address book database 7 such as the IP address 9 corresponding to the user name 12 of the partner. Thus, since the communication is made with the counterpart terminal 4, even when the terminal data of the counterpart changes, the latest IP address 9 or telephone number 11 can be obtained from the centrally managed address book database 7. Therefore, the IP address of the counterpart terminal 4 can be specified without depending on the access method.
