Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information providing system and device, a communication terminal device, and a program, and more particularly to an information providing system and device, a communication terminal device, and a program that realize simple and efficient push distribution.
[0002]
[Prior art]
So-called push distribution is known in which, when various information is distributed from a server to a client via a communication network such as the Internet, the updated information is automatically distributed. In such push distribution, the server manages each client and automatically distributes to connected clients (server-driven push), and the client periodically inquires of the server about distribution information ( Client-driven push or pseudo-push).
[0003]
In recent years, data communication such as Internet use and instant message exchange using a mobile communication terminal such as a mobile phone has been popular. In push distribution in such a mobile communication network, a pseudo push method is often used. For this reason, an inquiry is periodically transmitted from the mobile communication terminal as a client. In this case, even if there is no change in the distribution target information (content), an inquiry is made, and there are many useless inquiries, which imposes a load on network traffic. In addition, when a communication fee is generated for this inquiry transmission, the communication cost of the user also increases.
[0004]
On the other hand, push distribution is performed by notifying the mobile communication terminal of the client that there is information to be distributed, for example, by e-mail or SMS (Short Message Service), and accessing the server in response to this notification to obtain information. However, there is a case in which a communication fee is generated in the notification by e-mail, which increases the communication cost burden on the information distributor.
[0005]
In addition, in order to realize push distribution on a mobile communication network, for example, it may be necessary to use a predetermined call control protocol such as SIP (Session Initiation Protocol), etc., and these protocols are supported. There was also a problem that push distribution could not be done to terminals that did not.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and an object thereof is to provide an information providing system and device, a communication terminal device, and a program that realize simple and effective push distribution.
[0007]
[Means for Solving the Problems]
  In order to achieve the above object, an information providing system according to the first aspect of the present invention includes:
  An information providing system comprising a center and a plurality of communication terminal devices connected to each other via a communication line, and providing predetermined information from the center to each of the communication terminal devices,
  The center is
  Providing necessity determining means for determining whether or not a reason for providing predetermined information to the communication terminal device used by the user registered in advance has occurred;

  It is characterized by that.
[0008]
According to such a configuration, for example, when information is pushed and distributed to a mobile communication terminal (client) such as a mobile phone, the mobile communication terminal that is a delivery destination makes a call by voice communication, so that the mobile The incoming call from the distribution source (server) is recorded in the so-called incoming call history of the body communication terminal (push delivery notification). When there is an incoming call from the server in the incoming call history, the mobile communication terminal requests push delivery to the server to deliver predetermined information. The server side only needs to make a call to the target mobile communication terminal only when there is information to be distributed, so there is no need to periodically inquire the server from the client. For this reason, useless inquiries are eliminated, and the network load can be reduced. In addition, since the voice communication function that a normal mobile communication terminal naturally has is used, a special call control protocol or the like is not required, and push distribution can be easily realized for any terminal.
[0009]
Further, when a call is made from the server, for example, by disconnecting the line at the same time as the incoming call at the client, the client is caused to receive an incoming call so that a voice communication channel is not established between the server and the client. Thereby, it is possible to record the incoming call from the server in the incoming call history of the client without incurring a cost such as a communication charge, and it is possible to realize push distribution with reduced communication cost.
[0010]
Further, for example, in an instant message (IM) for exchanging messages according to the registered communication partner status (status), the communication partner is notified in real time that the status of a user has changed (push delivery). can do. In this case, the push delivery notification described above is performed only when the status of the target user changes, and the push delivery request from the client is also accompanied by this, so that it is efficient with minimal communication. Can provide and use IM services.

[0033]
The incoming call information storage unit 230 is composed of a rewritable storage device such as a flash memory, for example, and records information related to incoming calls in voice communication by the terminal device 200 (so-called incoming call history). It is assumed that the incoming call history includes at least the telephone number information of the caller.
[0034]
The program storage unit 240 is composed of, for example, a rewritable storage device such as a flash memory, and stores a predetermined operation program and necessary data for realizing each processing according to the present embodiment. Here, the operation program includes a program for performing communication by IM (hereinafter referred to as “IM program”). Information for specifying the center 100 in both voice communication and data communication (that is, a telephone number, an IP address, etc.) is stored in the program storage unit 240 together with the operation program. It is assumed that the operation program and data stored in the program storage unit 240 are provided from the center 100 via the communication network 20, for example.
[0035]
The state information storage unit 250 is composed of, for example, a rewritable storage device such as a flash memory, and the state of the terminal device 200 or the user detected based on the operation by the operation program stored in the program storage unit 240. Information (hereinafter referred to as “status information”) is stored. The status information includes information detected by the control unit 210 based on an operation program in addition to information input by a user. For example, when the user inputs “in meeting”, “busy”, etc., status information indicating that is stored. In addition, for example, when the IM program is not activated or when the terminal device 200 is powered off, the terminal device 200 can be set to, for example, “sleep state”, “ringtone OFF setting”, “(automobile In the case of a predetermined operation restriction state such as “during operation mode”, the control unit 210 detects them and stores status information indicating that.
[0036]
The input unit 260 includes, for example, a numeric keypad, other keys, and various switches, and a voice input device such as a microphone. The input unit 260 has predetermined information (such as a telephone number) and instructions (state setting and IM Input various instructions accompanying communication, etc.) and voice information.
[0037]
The output unit 270 includes, for example, a display device configured from a liquid crystal display device, a speaker, and the like, and outputs various operation screens, information received from the center 100, audio signals received through audio communication, and the like.
[0038]
Next, each process performed by the center 100 and the terminal device 200 in the information providing system 1 according to the present embodiment will be described with reference to the drawings.
[0039]
First, as pre-processing for push delivery by the center 100, terminal status notification processing by the terminal device 200 and push delivery preparation processing by the center 100 will be described with reference to the flowchart of FIG.
[0040]
The control unit 210 of the terminal device 200 detects the status of the terminal device 200 or the user (step S101). Here, as described above, in addition to the detection of the instruction input by the user using the input unit 260, the activation state of the terminal device 200 and the operation program is detected.
[0041]
If the detected status has changed from before detection (step S102: Yes), the control unit 210 controls the communication control unit 220 to indicate information indicating the detected status (hereinafter, “current status information”). Is transmitted to the center 100 (step S103). The current status information is also stored in the status information storage unit 250.
[0042]
After transmitting the current status information in step S103, or when the status has not changed (step S102: No), the control unit 210 detects whether or not the setting of the push delivery necessity flag has been changed (step S102). S104). Here, the flag is automatically changed according to a change by an arbitrary input by the user or a change in status detected in step S102. That is, the user may arbitrarily determine whether or not push distribution from the center 100 is necessary, or the current status changes to a state where IM communication is possible (for example, a change from “meeting” to “meal”, In response to a change from “sleep state” to “active state”), the flag may be automatically changed so that the control unit 210 requests push delivery. When the flag is changed (step S104: Yes), the communication control unit 220 is controlled, and information indicating the changed flag setting is transmitted to the center 100 (step S105).
[0043]
If there is no change in the flag (step S104: No), the process ends. This terminal state notification process is repeatedly executed as needed.
[0044]
On the other hand, in the center 100, when the data communication control unit 130 receives the current status information and / or the post-change flag information from the terminal device 200 (steps S201 and S203), the control unit 110 accesses the user information database 140 and responds. The “status” and / or “push delivery necessity flag” of the user's record to be updated is updated based on the received information (steps S202 and S204), and the process is terminated. This push delivery preparation process is repeatedly executed as needed. That is, the current “status” and “push delivery necessity flag” of each terminal device 200 are recorded in the user information database 140.
[0045]
Next, the delivery notification process by the center 100 will be described with reference to the flowchart of FIG. This distribution notification process is executed when the status information in the user information database 140 is updated (step S202).
[0046]
The control unit 110 refers to the record of the user whose status information has been updated, and determines whether or not another user ID is set for the “communication target user” (step S301).
[0047]
Here, when “communication target user” is set (step S301: Yes), the control unit 110 acquires user ID information of the communication target user (step S302). On the other hand, when there is no “communication target user” setting (step S301: No), the process ends.
[0048]
The control unit 110 accesses the user information database 140, refers to the “push delivery necessity flag” in the user ID record acquired in step S302, and determines whether the flag is ON (“1”). (Step S303). That is, it is determined whether or not the user desires push distribution of status information used for IM communication.
[0049]
Here, when the flag of the user is ON (step S303: Yes), the control unit 110 acquires voice communication terminal identification information (that is, a telephone number) from the record of the user (step S304). On the other hand, if the flag is OFF (“0”) (step S303: No), the process ends.
[0050]
The control unit 110 controls the voice communication control unit 120 to make a call to the telephone number acquired in step S304 via the communication network 10 (step S305). The control unit 110 detects whether or not the outgoing call is received by the counterpart terminal device 200 (step S306), and after detecting the incoming call (step S306: Yes), immediately disconnects the line (step S307). The process is terminated. Here, the line is disconnected before the communication path between the center 100 and the terminal apparatus 200 is established (that is, before the call becomes ready) by a response to an incoming call at the terminal apparatus 200 (for example, pressing of a call button). To do. For this purpose, the line is disconnected almost simultaneously with the incoming call at the terminal device 200. In this case, for example, the incoming call to the terminal device 200 can be detected by detecting the transmission of the calling signal by the local exchange having jurisdiction over the terminal device 200. Here, for example, the center 100 can monitor the voice signal in communication using the communication network 10 and detect the call signal transmission by detecting the difference in voice between the dial tone and the call signal.
[0051]
When the terminal device 200 receives a call signal from the local exchange, the terminal device 200 is notified of information indicating the telephone number of the caller (in this case, the center 100) and recorded in the incoming information storage unit 230 (incoming history). That is, since the communication path has not been established, the fact that there is an incoming call from the center 100 is recorded in the incoming call history of the terminal device 200 without incurring a communication cost such as a communication charge (call charge) for the voice communication. be able to. This implicitly notifies the target terminal device 200 that there is push distribution target information (in this case, status change of other users) (hereinafter referred to as “push distribution notification”).
[0052]
Next, push distribution request processing by the terminal device 200 that receives distribution notification from the center 100 and push distribution processing by the center 100 will be described with reference to the flowchart of FIG.
[0053]
When the push delivery request process shown in FIG. 7 is started at predetermined intervals by, for example, a treatment timer interruption, the control unit 210 of the terminal device 200 searches the incoming information storage unit 230 (step S401), and the incoming call history. It is determined whether or not telephone number information for designating the center 100 (hereinafter referred to as “center designation number information”) is recorded (step S402). The center designation number information is recorded in advance together with the operation program in the program storage unit 240, and the control unit 210 is recorded in the center designation number information and the incoming call history recorded in the program storage unit 240. The presence / absence of center designation number information is determined by comparing each telephone number information.
[0054]
When there is an incoming call from the center 100 (that is, a push delivery notification) (step S402: Yes), the control unit 210 refers to the current status information recorded in the state information storage unit 250 and can perform current IM communication. It is determined whether or not the current state (hereinafter, “communication possible state”) is established (step S403). Here, the communicable state refers to the case where the terminal device 200 and the activation state of the operation program are physically communicable, and the user is, for example, “meeting” or “during (car) driving”. A state other than a state not suitable for operation of the terminal device 200 or IM communication is assumed.
[0055]
When it is in a communicable state (step S403: Yes), the control unit 210 controls the communication control unit 220 and transmits a predetermined request command and inquiry command to the center 100 together with information for identifying the terminal device 200. In response to the push delivery notification from the center 100 (step S404).
[0056]
When there is no push delivery notification (step S402: No) or when communication is not possible (step S403: No), the process is terminated without making a response to the center 100.
[0057]
In the center 100, when the data communication control unit 130 receives a response from the terminal device 200 (step S501), the control unit 110 accesses the user information database 140 and refers to the user record of the terminal device 200 (step S502). ).
[0058]
The control unit 110 acquires, from the record, the user IDs of other users registered in the “communication target user” as the communication partner of the user. The control unit 110 refers to the record corresponding to the acquired user ID of the other user and acquires the status information of the other user (step S503).
[0059]
The control unit 110 controls the data communication control unit 130, transmits the status information of the other user acquired in step S503 to the requesting terminal device 200 (step S504), and ends the process.
[0060]
In the terminal device 200, the communication control unit 220 receives status information of other users from the center 100 (step S405), and ends the process. The terminal device 200 can acquire current status information of other users registered as communication partners, and uses this to perform desired IM communication.
[0061]
As described above, according to the information providing system 1 according to the embodiment of the present invention, push distribution can be performed to the target terminal device 200 only when the information to be distributed has changed. Reduces network load and enables efficient push delivery.
[0062]
In addition, the push delivery notification from the center 100 to the terminal device 200 is made by a call based on voice communication, and the communication path is not established, so the communication fee or the like is not generated from the center 100 to the push delivery notification. Moreover, since the push delivery request from the terminal device 200 is also made only when the delivery target information changes, the communication cost for the terminal device 200 can be minimized.
[0063]
Furthermore, notification of push delivery is performed using the voice communication function that is normally provided in normal mobile communication terminals, and various procedures for push delivery are made in response to this, so it is usually necessary to realize push delivery. No call control protocol is required. Therefore, push distribution can be performed even for terminals that do not support such a protocol.
[0064]
In the above embodiment, the case where push distribution of status information used for IM communication between users has been described as an example, but the application target of the present invention is not limited to this. For example, the present invention can also be applied to push distribution of news, various software, and the like.
[0065]
In the above embodiment, in the push delivery notification from the center 100 to the terminal device 200, the line is disconnected at the same time as the incoming call at the terminal device 200 in order not to establish the communication path, but if the communication path is not established, The method is arbitrary. For example, an operation program on the terminal device 200 side may be controlled so as to identify a center designation number for incoming calls and not establish a communication path. For example, when the center designation number is recognized, a predetermined response command or the like may be returned, and the center 100 may disconnect the line accordingly.
[0066]
In the above embodiment, whether or not the push delivery notification has been made is determined by referring to the incoming call history, but any method can be used as long as a response to the push delivery notification is possible. Applicable. For example, the operation program of the terminal device 200 determines whether it is an incoming call from the center 100 at the same time as an incoming call (that is, whether it is a push delivery notification), and responds immediately if necessary. Good. In this case, the center 100 may be inquired about the presence or absence of push distribution target information without determining whether or not the telephone number for incoming calls is a center designation number. Thus, the present invention can be applied even when the terminal device 200 cannot record the caller's telephone number information in the incoming call history.
[0067]
In the above embodiment, a mobile communication terminal has been described as an example of the terminal device 200. However, any device can be adopted as the terminal device 200 as long as both voice communication and data communication are possible. In this case, for example, a personal computer or a PDA (Personal Data Assistance: portable information terminal) to which a communication device such as a modem capable of performing voice communication and data communication is connected (or mounted) may be used.
[0068]
Note that the center 100 according to the embodiment of the present invention can be realized using a normal computer system, not a dedicated system. For example, by installing the program from a recording medium (such as a flexible disk or a CD-ROM) that stores the program for executing the above-described process in a general-purpose computer, the center 100 that executes the above-described process is configured. Can do.
[0069]
Similarly, for the terminal device 200 according to the present embodiment, the terminal device 200 according to the present embodiment can be configured by installing a program for executing the above-described processing in an arbitrary device. .
[0070]
The means for supplying these programs is arbitrary. In addition to being able to be supplied via a predetermined recording medium as described above, for example, it may be supplied via a communication line, a communication network, a communication system, or the like. In this case, for example, the program may be posted on a bulletin board (BBS) of a communication network and provided by superimposing it on a carrier wave via the network.
