JP4595486B2 - Presence information providing system, method thereof, and presence server - Google Patents

Description

  The present invention relates to a presence information providing system in a presence service, a method thereof, and a presence server.

  In a group call or the like as a usage form of a presence service, for example, when talking to a communication partner in an instant messaging service or a Push-To-Talk service, the user first determines the status of another user who is a communication partner. It is necessary to confirm and is used to confirm the status of the user who is the communication partner.

  In the following description, “presence information” of the presence service is information representing the state of the device or the state of the user of the device. For example, “Online” and “On” indicating whether the device is connected to the network. Information such as “offline” and “response possible” and “response impossible” indicating whether the user of the communication device can immediately respond. When in doubt about the meaning of a term, it basically follows the meaning defined in RFC2778: “A Model for Presence and Instant Messaging” published by the IETF (Internet Engineering Task Force), but is limited to that. It is not a thing.

  In recent years, with the expansion of instant messaging services such as American Online and Microsoft Messenger, it is possible to exchange messages in real time using a network. There are a wide range of services that allow you to enjoy conversations (hereinafter referred to as chat) using a communication network, even though you are away. This service is spreading not only in fixed networks via the Internet but also in mobile communication networks.

  In such an instant messaging service, when each user registers as a group member in the server with the user terminal, each user can refer to the presence information of other users when accessing the server with the user terminal.

Here, a technology has been proposed in which a chat start event is generated and chat is simultaneously started between a plurality of user terminals when presence information of a specific user indicates that communication is possible (see, for example, Patent Document 1).

  According to the presence information providing system, the method thereof, and the presence server of the present invention, the presence service can be started with a combination of the presence statuses of the group members as a trigger.

  Next, the configuration of an embodiment of the present invention will be described with reference to the drawings. Note that the presence service that is started by a combination of the presence statuses of group members includes various types of services such as terminal application activation, e-mail transmission / reception, chat start, etc. Details about the start.

  Referring to FIG. 1, the presence information providing system according to the present embodiment includes terminals 10 a to 10 c and a presence server 20, which are connected via a packet communication network 100 and a mobile communication network 200. The communication method may be wired or wireless.

  The terminals 10a to 10c are information processing apparatuses that are used by a user to perform a group call. For example, a mobile phone, a PDA (Personal Digital Assistant), a notebook computer, and the like.

  When the terminal 10 responds to the group call start call from the group call control unit 23 of the presence server 20, the group call is started. When the group call is started, each user's terminal 10 is connected to the group call control unit 23 of the presence server 20, and the voice from the user's terminal 10 is sent to another user via the group call control unit 23 of the presence server 20. It is transmitted to the terminal 10.

  Further, the terminal 10 has a function of transmitting the presence status such as the current location, status, and physical condition to the presence status management unit 21 of the presence server 20 via the packet communication network 100.

  Also, the terminal 10 edits the group call start condition table 221 of the group call start condition storage unit 22 via the packet communication network 100, and automatically sets the group member's presence status to any combination when the group is in any combination. It has a function for setting conditions for starting a call.

  The presence server 20 is an information processing apparatus such as a workstation, which includes a presence state management unit 21, a group call start condition storage unit 22, and a group call control unit 23.

  The presence state management unit 21 has a function of receiving the presence state from each terminal 10 via the packet communication network 100 and reflecting the presence state in the presence state management table 211. Here, the presence status management table 211 manages the presence status such as the location, status, and physical condition of each user, and may be configured by a table on the database.

  The group call start condition storage unit 22 has a function of editing the group call start condition table 221 with information from the terminal 10 via the packet communication network 100. Here, the group call start condition table 221 holds a condition for automatically starting a group call when the presence status of each group member becomes any combination, and is configured by a table on the database. May be.

  Referring to FIG. 3, in detail, before starting the group call, the user edits the group call start condition table 221 provided in the group call start condition storage unit 22 from the terminal 10 via the packet communication network 100 in advance. To do. First, in condition 1, it is assumed that user A is a grandfather and user B and user C are the family of user A. When the user B who is a family and the user A who is a grandfather when the user C is out, the group call is automatically started by all the group members when the physical condition becomes poor at home alone. In the case of such a critical situation, it becomes possible to automatically communicate with each other by a group call with the whole family, and it is possible to live a life with peace of mind.

  In condition 2, it is assumed that user A, user B, and user C are office workers and hold a conference by group call from AM 10:00. When AM 10:00, which is a predetermined meeting time, is reached, a group call is called to all group members who are in “presence state = working”. At that time, group members who are on vacation or are participating in different meetings are not called.

  Under condition 3, user A, user B, and user C are in a group of friends, and when a situation occurs in which a plurality of friends who are in free time rather than work etc. are gathered near “Shibuya”, a group call occurs. Assumes to start.

  The group call control unit 23 is connected to the terminal 10 via the mobile communication network 200 and has a function of receiving voice from the terminal 10 of the speaking user and transmitting it to the terminal 10 of the non-speaking user during the group call.

  The packet communication network 100 relays the presence status of each user transmitted from the terminal 10 to the presence status management unit 21. Each user relays communication when the group call start condition table in the group call start condition storage unit 22 is edited from the terminal.

  The mobile communication network 200 is a network that connects the terminal 10 and the presence server 20. In particular, it is used when the group call control unit 23 of the presence server 20 communicates with the terminal 10.

  Next, with reference to FIG. 2 to FIG. 4, the flow of processing for starting a group call triggered by a combination of presence statuses of group members in the present embodiment will be described in detail based on the flowchart of FIG. .

  First, the user notifies his / her presence status from the terminal 10 to the presence status management unit 21 of the presence server 20 via the packet communication network 100 (step S501). This notification of the presence state may be performed automatically at an arbitrary timing, continuously, or manually.

  The presence status management unit 21 of the presence server 20 reflects the received presence status information in the presence status management table 211 (step S502). When there is a change in the presence status of the user, the presence status management table 211 is notified by the presence status management unit 21 of the presence server 20 being notified of the changed presence status from the terminal 10 via the packet communication network 100. It is possible to always maintain the current presence state of each user.

  Next, the presence state management unit 21 of the presence server 20 inquires of the presence state management table 211 and the group call start condition table 221 included in the group call start condition storage unit 22 of the presence server 20 (step S503). It is checked whether or not the automatic group call start condition is satisfied by the presence status change (step S504). The group call start condition storage unit 22 may be configured by a predetermined database provided on the hard disk.

  As a result of the inquiry by the presence state management unit 21 of the presence server 20 described above, when the group call start condition is not satisfied (step S504 / No), the group call start from the presence state combination is not performed and the next presence from the terminal 10 is not performed. Wait for state change notification.

  On the other hand, if the group call start condition is satisfied as a result of the inquiry by the presence state management unit 21 of the presence server 20 (step S504 / Yes), the group call from the presence state combination is started.

  That is, first, the presence state management unit 21 of the presence server 20 transmits a group call start instruction signal to the group call control unit 23 (step S505). Here, the group call start instruction signal includes information on a group call transmission target user. The group call outgoing users are users who meet the group call outgoing target conditions stored in the group call start condition table 221 with reference to the presence status management table 211 by the presence status management unit 21 of the presence server 20. It is determined by selecting.

  When the group call control unit 23 of the presence server 20 receives the group call start instruction signal from the presence state management unit 21 of the presence server 20, the terminal 10 of the group call transmission target user included in the group call start instruction signal is included. In response to this, a group call is made via the mobile communication network 200, and the terminal 10 is ringed (step S506). Note that the mobile communication network may be configured by an arbitrary network.

  When each user receives an incoming call by pressing the off-hook button of the terminal 10, a group call is started (step S507).

  As another embodiment, in the above embodiment, when the presence state management unit 21 of the presence server 20 receives the presence state change from the terminal 10, the group call start condition storage of the presence server 20 is stored. Instead of determining whether or not the group call start condition is satisfied with reference to the group call start condition table 221 of the unit 22, whether or not the group call start condition storage unit 22 satisfies the group call start condition at a predetermined timing May be determined. For example, referring to FIG. 3, when it becomes AM10: 00 of a predetermined meeting time in the condition 2, the group call start condition storage unit 22 of the presence server 20 determines whether or not the group call start condition is satisfied. Then, the presence state management unit 21 of the presence server 20 sends a group call start instruction signal to the group call control unit 23 of the presence server 20. There may be. Since the subsequent operations are the same as those in the above embodiment, a duplicate description is omitted.

  As another embodiment, instead of the user editing the group call start condition table 221 of the group call start condition storage unit 22 of the presence server 20 from the terminal 10 via the packet communication network 100, the group call organizer A configuration may be such that a person or the like accesses the group call start condition storage unit 22 of the presence server 20 via the Internet and edits the group call start condition table 221.

  Each embodiment described above is a preferred embodiment of the present invention, and various modifications can be made without departing from the gist of the present invention. For example, the processing for realizing the functions of the present system may be performed by causing each device to read and execute a program for realizing the functions of the terminal 10 and the presence server 20 in the above embodiment. Further, the program is transmitted to another computer system by a transmission wave via a CD-ROM, a magneto-optical disk or the like which is a computer-readable recording medium, or via the Internet or a telephone line which is a transmission medium. Also good.

  In each of the above-described embodiments, the system configuration in which the presence server 20 is connected as a single device has been described. However, the present invention can also be applied to a configuration in which a plurality of server devices are added for each function. Of course.
