Description

  The present invention relates to a communication network system and a telephone that enable browsing of Web pages together with telephone conversations.

  In recent communications, in addition to telephone networks such as wired telephones, mobile telephones, and Internet telephones, electronic mail communications via the Internet are frequently used. Furthermore, various information is provided through a Web page (homepage) via the Internet.

  As described above, in the telephone network, only telephone conversation, facsimile communication, and data communication are performed, and in the Internet, in addition to electronic mail communication, provision of various information and Internet telephones by browsing web pages worldwide. Was done. Furthermore, communications are being conducted for various and advanced communications using both telephone conversations and browsing of web pages on the Internet.

  As communication in this communication, for example, a telephone caller makes a business meeting with a person who is scheduled to travel far away through a telephone call, and browses a local weather forecast Web page of the business trip to each other, There is communication (communication based on cooperation between telephone conversations and Web page information) for improving work efficiency, such as deciding to hold an outdoor exhibition at a visit based on a forecast.

  As a communication system for linking such telephone conversation and Web page information, Patent Document 1 proposes a communication method and system by linking a telephone call and Web page browsing.

  In the above-described method and system, URIs (Uniform Resource Identifiers) corresponding to the telephone numbers of the destinations are transmitted from the caller telephone to the callee telephone through a predetermined network. The receiving small-sized general-purpose computer accesses the received URI Web page through the network, displays the Web page, and transmits the URI from the receiving side to the calling-side small general-purpose computer. Then, the small-sized general-purpose computer on the transmission side accesses the web page corresponding to the received URI through the network and displays the web page. Then, the telephone on the calling side and the telephone on the receiving side are line-connected.

  While referring to the display screen of this Web page, the calling side and the called side have a conversation through the telephone. That is, communication is performed by cooperation of telephone conversation and Web page information. In this case, it is possible to easily refer to the web page between the caller and the callee only by making a phone call, and even if the content of the webpage cannot be accurately and quickly transmitted only by telephone conversation. Coordination with information content enables smooth and complete communication.

  A variety of examples have been proposed as application examples of communication in this case. For example, as described above, there is an example in which a web page of a local weather forecast of a business trip destination is browsed and the business meeting is performed. In addition, there is an example of communication in which stock prices in two remote stock markets are displayed on the screen by notifying their URIs and considered together with telephone conversations.

  In the method of Patent Document 1, the calling side transmits a URI corresponding to the telephone number of the telephone destination stored on the calling side to the receiving side telephone. Then, the receiving side transmits a URI corresponding to the telephone number stored at the receiving side to the calling side telephone. Therefore, the Web page that is finally displayed on the caller side is a Web page corresponding to the URI stored by the other party (caller) in association with the telephone number of the caller (caller).

  However, there are not a few situations in which the sender side requests a lot of information on the called side in situations where a telephone conversation and information on a Web page need to be linked. For example, in order to ask about the menu of the store while calling a restaurant, it is common to browse the Web page of the store displaying the menu. Patent Document 1 does not sufficiently cope with such a situation.

As described above, according to the present invention, it is possible to acquire a partner's Web page including various contents only by a telephone call and to browse the Web page on its own terminal. Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 2 shows a conceptual diagram of the communication network system according to the first embodiment of the present invention. In this network system, a telephone call is made between two terminals A and B. Here, the terminal A is configured by a telephone having a function (browser) that can be connected to a network such as the Internet. A typical example of the terminal A is a mobile phone, but it can also be composed of a fixed terminal having a telephone call function and a network connection function. On the other hand, the terminal B can use a telephone that has a telephone call function but does not have a browser, that is, does not have a network connection function. Accordingly, the terminal B can be configured by a normal landline telephone. The terminal A includes a display (display unit) that displays a Web page, but the display can be provided in a device separate from the terminal A.

  In the present embodiment, the two terminals A and B are both mobile phones, and both are connected so as to be able to talk over a mobile phone network (telephone line) through a base station (BS). When both terminals are connected by a wired line, a base station is not necessary.

  Furthermore, in the present embodiment, a URL search server C (resource identifier search server) that constitutes a resource identifier accumulation unit and a Web content server D that constitutes a content accumulation unit are arranged on the network. The URL search server C receives the telephone number of the terminal B from the terminal A, and transmits a URL (Uniform Resource Locator) as a resource identifier associated with the telephone number to the terminal A. Also, the Web content server D receives the URL from the terminal A, and the content constituting the Web page corresponding to the URL (including all components of the Web page such as documents, images, sounds, hyperlinks, etc.) To terminal A.

  In this embodiment, communication is performed according to the following procedure.

(1) The user of terminal A performs a normal call start operation on terminal B.
(2) Along with the call start operation, the terminal A requests the URL of the Web page prepared by the terminal B to the URL search server C.
(3) The URL search server C transmits the searched URL to the terminal A.
(4) The terminal A requests the web content server D for the web content of the acquired URL.
(5) The Web content server D transmits the Web content of the URL to the terminal A. Terminal A displays a Web page including the content.
(6) Terminal A and terminal B start a call.

  In FIG. 2, for convenience of illustration, two networks are shown, but information can be transmitted and received through one network. It is also possible to carry out the steps (2) to (5) at the same time as the above step (6) or after the step (6).

  Next, the processing procedure of the terminal A during communication will be described using the flowchart shown in FIG. First, the user of terminal A performs a call operation (call) to terminal B (step S11).

  At this time, it is determined whether or not the URL of the terminal B is held in a predetermined memory that stores the call history in the terminal A (step S12). When it is determined that the URL of the terminal B is not held (step S12; No), the terminal A transmits the telephone number of the terminal B to the URL search server C, thereby requesting the URL of the terminal B from the server C. (Step S13), the terminal A analyzes the received data corresponding to the request (Step S14). On the other hand, if it is determined that the URL of the terminal B is held (step S12; Yes), the terminal A does not request the URL of the terminal B from the server C, and performs the process of step S16 described later.

  When the URL of the terminal B does not exist in the analyzed received data (step S15; No), the call between the terminal A and the terminal B is started without any operation such as a web page request (step S18). On the other hand, when the URL of the terminal B exists in the analyzed received data (step S15; Yes), the terminal A requests the Web content server D for the Web content of the acquired URL, and acquires the Web content (step S15). S16) A web page including the web content is displayed on its own display (step S17). Thereafter, a call between the terminal A and the terminal B is started (step S18).

  Next, the processing procedure of the URL search server C during communication will be described using the flowchart shown in FIG. When receiving the URL acquisition request from the terminal A (step S21), the URL search server C searches the URL from its own database (step S22). This search is performed from a predetermined table in which the telephone number and the URL are associated in advance using the telephone number of the terminal B.

  If the corresponding URL does not exist (step S23; No), an error display indicating that the URL does not exist is set as a response (step S24), and a response to the search request is transmitted to the terminal A (step S26). ). When the corresponding URL exists (step S23; Yes), the URL is set as a response (step S25), and a response to the search request is transmitted to the terminal A (step S26).

  FIG. 5 is a sequence diagram showing a processing procedure among the terminal A, the URL search server C, the terminal B, and the Web content server D, and summarizes the description so far. In the first step of the terminal A, the user of the terminal A can select the display mode and non-display mode of the web page on the display of the terminal A. The steps described thereafter are steps after the Web page display mode is selected.

  Further, FIG. 5 illustrates that “calling” and “communication start” after the calling operation are performed after the Web page of the terminal A is displayed. However, the timings of “calling” and “communication start” are arbitrary, and can be set at any time between “calling operation” and “web page display”.

  A block diagram of the terminal 100 constituting the terminal A is shown in FIG. The terminal 100 includes a communication unit 101, a URL reception unit 103, a URL acquisition request transmission unit 105, a URL acquisition control unit 107, a call / browser control unit 109, a browser activation control unit 111, a browser 113, a call A start control unit 115, a call unit 117, a URL holding / non-holding determination unit 119, a call operation control unit 121, a telephone book (resource identifier storage unit) 123, and a display (display unit) 125 are provided.

  When the user of the terminal A performs a call operation (calling) to the terminal B, the call operation control unit 121 activates the URL holding / non-holding determination unit 119. Then, the URL holding / non-holding determining unit 119 searches the call history stored in the phone book 123 configured by a predetermined storage device that stores the call history, and determines whether the URL of the terminal B is held. To do. When it is determined that the URL of the terminal B is not held, the call / browser control unit 109 activates the URL acquisition control unit 107. The URL acquisition control unit 107 transmits the telephone number of the terminal B to the URL search server C via the URL acquisition request transmission unit 105 and the communication unit 101, and simultaneously requests the URL of the terminal B from the server C. The URL acquisition control unit 107 and the URL acquisition request transmission unit 105 constitute a resource identifier acquisition unit.

  When receiving the received data corresponding to the request, the call / browser control unit 109 analyzes the received data. When the URL of the terminal B does not exist in the analyzed received data, when the call / browser control unit 109 activates the call start control unit 115, a telephone line connection with the terminal B is performed via the call unit 117.

  When the URL of terminal B exists in the analyzed received data, the URL is received by the URL receiving unit 103 under the control of the URL acquisition control unit 107. The call / browser control unit 109 activates the browser 113 by the browser activation control unit 111 and requests the web content server D for the obtained web content of the URL via the communication unit 101. When the web content is acquired, a web page including the web content is displayed on the display 125. The browser activation control unit 111 and the browser 113 constitute a content acquisition unit. Thereafter, when the call / browser control unit 109 activates the call start control unit 115, a telephone line connection with the terminal B is performed via the call unit 117.

  A block diagram of the server 200 constituting the URL search server C is shown in FIG. The server 200 includes a URL search unit 201, a URL transmission unit 203, a telephone number acquisition unit 205, a communication unit 207, and a URL information database 209.

  When receiving the URL acquisition request from the terminal 100 (terminal A), the telephone number acquisition unit 205 acquires the telephone number of the terminal B via the communication unit 207. Then, the URL search unit 201 searches the URL information database 209 for the URL. This search is performed using a table that stores the telephone number and URL of the counterpart terminal shown in FIG. This table is stored in the URL information database 209, and telephone numbers and related URLs are stored in a two-dimensional matrix format.

  If the corresponding URL does not exist, the URL transmission unit 203 sets an error display indicating that the URL does not exist as a response, and transmits a response to the search request to the terminal A. If there is a corresponding URL, the URL transmission unit 203 sets the URL as a response, and transmits a response to the search request to the terminal A via the communication unit 207.

  The URL information database 209 does not necessarily have to be physically stored in the server 200, and can be configured by a storage device such as a separate hard disk connected to the server 200. Further, the URL information database 209 can be provided in another server accessible from the server 200.

(Second Embodiment)
FIG. 9 shows a conceptual diagram of a communication network system according to the second embodiment of the present invention. In this network system, the terminal A is configured in the same manner as in the first embodiment, but the configuration of the terminal B is different from that in the first embodiment. The terminal B in this embodiment has a browser as well as a telephone call function, that is, a network connection function. In the present embodiment, the Web content server D exists on the network, but the URL search server C in the first embodiment does not exist. In this embodiment, communication is performed according to the following procedure.

(1) The user of terminal A performs a normal call start operation on terminal B.
(2) Along with the call start operation, the terminal A requests the URL of the Web page prepared by the terminal B to the terminal B itself.
(3) Terminal B transmits its URL to terminal A.
(4) The terminal A requests the Web content server D for the Web content of the URL of the acquired terminal B.
(5) The Web content server D transmits the Web content of the URL to the terminal A. Terminal A displays a Web page including the content.
(6) Terminal A and terminal B start a call.

  As in FIG. 2, two networks are shown in FIG. 9 for convenience of illustration, but information can be transmitted and received through one network as a matter of course. It is also possible to carry out the steps (2) to (5) at the same time as the above step (6) or after the step (6).

  Next, the processing procedure of terminal A during communication will be described using the flowchart shown in FIG. First, the user of terminal A performs a call operation (calling) to terminal B (step S31).

  At this time, it is determined whether or not the URL of the terminal B is held in a predetermined memory that stores the call history in the terminal A (step S32). When it is determined that the URL of the terminal B is not held (step S32; No), the terminal A requests the URL from the terminal B (step S33), and the terminal A analyzes the received data for the request (step S33). Step S34). On the other hand, when it is determined that the URL of the terminal B is held (step S32; Yes), the terminal A does not request the URL from the terminal B, and performs the process of step S36 described later.

  If the URL of the terminal B does not exist in the analyzed received data (step S35; No), the call between the terminal A and the terminal B is started without an operation such as a web page request (step S38). On the other hand, when the URL of the terminal B exists in the analyzed received data (step S35; Yes), the terminal A requests the Web content server D for the Web content of the acquired URL, and acquires the Web content (step S35). S36) A web page including the web content is displayed on its own display (step S37). Thereafter, a call between the terminal A and the terminal B is started (step S38).

  Next, the processing procedure of terminal B at the time of communication will be described using the flowchart shown in FIG. When receiving the URL acquisition request from the terminal A (step S41), if the terminal B does not have its own URL (URL corresponding to its own telephone number) (step S42; No), the fact that the URL does not exist Is set as a response (step S43), and a response to the search request is transmitted to the terminal A (step S45). If it has a corresponding URL (step S42; Yes), the URL is set as a response (step S44), and a response to the search request is transmitted to the terminal A (step S45).

  The steps (1) to (6) described above are achieved by carrying out the above steps and step S49 described later. In this embodiment, the terminal B, together with the incoming call from the terminal A, adds itself as an additional function. The Web page is displayed on the display (displayed with a dotted line in FIG. 9). This additional function is achieved in steps S46 to S49 described below.

  After step S45, the terminal B determines whether or not a cache corresponding to the history of accessing its web page exists in its own memory (step S46). If the cache does not exist (step S46; No), the web content is requested from the web content server D, the web content is acquired (step S47), and the web page including the web content is displayed on its own display ( Step S48). Thereafter, a call between the terminal A and the terminal B is started (step S49). If the cache exists (step S46; Yes), the web content is not requested to the web content server D, and the web page is displayed on its own display based on the cache (step S48). Thereafter, a call between the terminal A and the terminal B is started (step S49).

  FIG. 12 is a sequence diagram illustrating a processing procedure between the terminal A, the terminal B, and the Web content server D, and summarizes the description so far. Similar to FIG. 5, the timing of “call start” is arbitrary, and can be set to any point in time between “call operation” and “web page display”. Further, the timing of the exchange between the terminal B and the web content server D (step S46 to step S49 in FIG. 11) is also arbitrary, and can be performed at a timing unrelated to the exchange between the terminal A and the web content server D. is there.

  The configuration of the terminal A in the present embodiment is the same as the configuration in the first embodiment shown in FIG. FIG. 13 shows a block diagram of the terminal 150 constituting the terminal B in the present embodiment. The terminal 150 includes a communication unit 101, a URL transmission unit 129, a URL request reception unit 131, a URL notification control unit 127, a call / browser control unit 109, a browser activation control unit 111, a browser 113, and a call start. A control unit 115, a call unit 117, a display 125, and a memory (resource identifier storage unit) 133 that stores the URL of the terminal B are provided. Each of communication unit 101, call / browser control unit 109, browser activation control unit 111, browser 113, call start control unit 115, call unit 117, and display 125 is the same as that of terminal 100 in FIG. It is comprised similarly.

  When the URL request receiving unit 131 controlled by the URL notification control unit 127 receives a URL acquisition request from the terminal A via the communication unit 101, the call / browser control unit 109 stores its own URL in the memory 133. If not, an error display indicating that the URL does not exist is set as a response, and the URL transmission unit 129 transmits a response to the search request to the terminal A. When the corresponding URL is stored in the memory 133, the URL is set as a response, and the URL transmission unit 120 transmits a response to the search request to the terminal A.

  Further, the call / browser control unit 109 controls the browser 113 by activating the browser activation control unit 111 and displays the Web page of the terminal B itself on the display 125. Thereafter, when the call / browser control unit 109 activates the call start control unit 115, a telephone line connection with the terminal B is performed via the call unit 117.

  According to the present invention, it is possible to acquire a Web page (homepage) using only a telephone number during a call, and this technology is achieved by a combination of a conventional telephone function and a browser.

And according to the present invention,
It is possible to automatically acquire the URL of the other party only by the call operation and automatically start displaying the web page. For this reason, it is possible to easily make a telephone conversation while viewing the other party's Web page. Since it is possible to browse a Web page from which a large amount of information about the other party can be obtained, communication can be facilitated and advanced.

 In addition, since the terminal itself obtains the URL and Web page of the other party simultaneously with the call, it is possible to obtain the other party's Web page smoothly and quickly. If the URL of the other party is held in the terminal, it is expected to obtain the Web page more quickly.

  In the present invention, the type of the telephone line is not particularly limited, and the present invention can be applied to a scene of a telephone call through any telephone network such as a wired telephone, a mobile telephone, and an Internet telephone. In the case of an Internet telephone, a voice signal converted into data passes through the Internet, and in this situation, the telephone line and the network are made common.

  Further, in this specification, the “resource identifier” includes all kinds of objects that can identify resources on the network, including URI, URL, URN (Uniform Resource Name), and the like.

  In addition, for requesting and transmitting resource identifiers (URLs in the embodiment), various communication formats according to network modes such as TCP / IP (Transmission Control Protocol / Internet Protocol) and SMS (Short Message Service) are adopted. There is no particular limitation.

  Although various embodiments of the present invention have been described above, the present invention is not limited to the matters shown in the above-described embodiments, and those skilled in the art can make modifications and applications based on the description and well-known techniques. This is also the scope of the present invention, and is included in the scope of seeking protection.
