Description

Specification

Technical field of IMPS system, IMPS client device, IMPS provision method, and program

[0001] The present invention includes a plurality of IMPS (Instant Message and Presence Service) client devices and an IMPS server device as components, and the IMPS between the plurality of IMPS client devices. The present invention relates to an IMPS system, an IMPS client device, an IMPS providing method, and a program that transmit / receive presence information via a server.

Background art

[0002] IMPS (Instant Message and Presence Service) system power is known as a communication tool using the Internet (see, for example, Patent Document 1).

[0003] Here, IM (instant message) service is a system that relays and forwards a message transmitted from a terminal on the transmission side to a partner terminal via a server in real time. In a normal e-mail system, sent mail is stored in the mailbox of the other party on the Internet, and the receiving user needs to download the mail from the mailbox. However, using the IM service eliminates the need for cumbersome processing such as downloading emails, and allows users to exchange messages in real time with a specific party that has been approved in advance.

[0004] Also, PS (Presence Service) is the sharing of “presence information” that indicates the status (status) of a user who uses the communication network among the members of the group, which allows the current status of the user to be It is a communication service that realizes “only now, only here, and only your own communication” in line with the situation.

[0005] The “status” of the user indicated by the presence information is generally interpreted in a very broad sense, for example, the user's current online / offline connection status, busy / free time, watching / not watching the monitor. As well as the current location of the user, It is thought to include all sorts of conditions, such as the desires, demands, and time that a person has at that time.

[0006] A user can update his / her presence using his / her communication terminal. The updated presence information can be sent unconditionally in real time to other group members who wish to obtain that user's presence information and have approved it.

[0007] In addition, a person who desires to obtain the presence information of other users Each time, the user is asked for approval, and the presence information is provided only within the range approved by the user. A form of providing presence information is also allowed.

[0008] Protocols used for IMPS are based on the standard specifications of ○ MA (Open 'Mopile' Alliance: an industry group that was established by a group of mobile communication companies and aims to standardize standards). is doing.

[0009] It should be noted that “IM (instant messaging) service” and “PS (presence service)” are the most effective services when they are combined with each other. Because it can be provided, the presence service (PS) is regarded as an evolved form of IM service, and both services may be collectively referred to as “instant messaging service” or “instant messaging”. Some people call it “presence service” with an emphasis on sharing. Although these expressions are different, it is considered that there is no difference in the actual contents.

[0010] Here, in this specification, IMPS (Instant Message 'and' Presence Service) that combines IM (Instant Message) Service and PS (Presence Service) from the viewpoint of accurate description of service contents. ) Is used. However, as mentioned above, the fact that an immediate exchange of messages is possible means that it is possible to exchange and share instant presence information, so it is necessary to stick to the name of the service. There is no.

Disclosure of the invention

Problems to be solved by the invention [0011] IMPS (Instant Message 'and' Presence Service) is a technology that realizes real-time transfer of messages or presence as described above, and realizes "information sharing" at that time. In other words, the current IMPS stops at the “information sharing stage” between members connected by a communication network, and what is to be done between the members using the shared information is as follows. Depends on the voluntary device operation of each member.

[0012] Therefore, for example, if the presence information of another member arrives at a communication terminal of a certain member, but the member forgets to check the presence information, the presence information is generated at the end. No positive action is taken.

[0013] In addition, the member power S that has received presence information of other members, the power S that the presence information is checked S, and how to utilize the presence information for the next action, do not think, and take the next action In this case as well, in the end, there will be no positive action based on the presence information.

[0014] Thus, the current IMPS (Instant Messaging 'and' Presence Service) relies on each user's voluntary behavior in terms of “active use of shared information”, and therefore It is not necessarily a situation where IMPS (Instant Messaging 'and' Presence Service) has the full potential.

[0015] The present invention has been made on the basis of such considerations, and the functions of IMPS (Instant Message & Presence Service) are improved from the viewpoint of active use of shared information. The purpose is to expand, enhance the content of IMPS, and promote the diversification of IMPS usage.

Means for solving the problem

[0016] An IMPS system of the present invention includes a plurality of IMPS client devices and an IMPS server device, and transmits and receives presence between the plurality of IMPS client devices via the IMPS server. The presence includes an application identifier that specifies an application to be activated in the IMPS client device that receives the updated presence, and time information for specifying the activation time of the application. And the IMPS client device received A presence analysis unit that specifies an application to be started and a starting time from the application identifier and the time information included in the presence, and schedule management that manages a schedule for starting the application at the specified starting time And an application activation unit that activates the application at the activation point.

[0017] While the OMA standard specifications do not define a protocol for transferring presence information, the presence information is allowed to be extended. Focusing on this point, in the present invention, an application identifier for designating an application to be activated and time information indicating the activation time are newly added to the presence attribute value list included in the presence information. In addition, the IMPS service layer, which is the top layer of the IMPS client program, reads and analyzes the above newly added information, functions for managing schedules, and under the condition that user approval has been obtained. Add a new function to start the specified application at the specified time.

[0018] Thereby, the IMPS client program on the side that has received the presence information can start the specified application at the specified start time. Here, the expanded presence information functions as a kind of message that is sent from the sender to the receiver to encourage participation in the communication. As a result, the sender makes a separate call (call) to the receiver. You can easily communicate your intentions to the other party without having to do it. On the other hand, even if the receiver does not perform any special device operation, the receiving IMPS client reads the sender's intention and voluntarily launches the necessary application at the timing desired by the client sending the presence information. Is possible.

[0019] Therefore, even if the sender does not make a special action (call), and even if the receiver does not perform a special device operation to participate in communication in response, Collaboration between the IMPS client device and the receiving IMPS client device (such as establishing a link for communication) is automatically realized. This makes it possible to start a chat or video conference by a predetermined member from a predetermined time, or to receive an e-mail or a video letter from a communication partner at a desired time. This can be achieved naturally and easily. In other words, presence information From the perspective of the user on the sending (updating) side, it is now easier to realize the environmental power S that enables you to enjoy optimal communication in your own situation.

. This contributes to increasing the attractiveness of IMPS and promoting its use.

[0020] Further, the IMPS client device of the present invention is an IMPS client device that transmits and receives presence via an IMPS server, and the presence is received in the IMPS client device on the side of receiving the updated presence. An application identifier that specifies an application to be activated, and time information for specifying the activation point of the application, and is activated from the application identifier and the time information included in the received presence. A presence analysis unit that identifies an application to be started and a starting point, a schedule management unit that manages a schedule for starting the application at the specified starting point, and an application starting unit that starts the abrasion at the starting point Ready It is intended.

[0021] As a result, client devices that support IMPS (instant message 'and' presence service) (portable terminals such as mobile phone terminals and PDAs, terminals and devices with image capturing and editing functions, and provision of predetermined information) (Including various devices such as server-type devices that can be performed).

[0022] The IMPS client device of the present invention is a portable terminal having a communication function.

[0023] IMPS (instant message and presence service) is originally positioned as a communication tool for mobile communication terminals. The mobile terminal supporting IM PS improved according to the present invention is not limited to the passive function of sharing information, but has a more aggressive function of realizing communication that vigorously uses the information, Multifunctionality of mobile terminals and improvement of practical value will be realized.

[0024] Further, the IMPS providing method of the present invention is an IMPS providing method in which presence is transmitted / received between a plurality of IMPS client devices via an IMPS server, and a user of one IMPS client device transmits presence information. And an application identifier for designating the application to be started in the IMPS client device that receives the updated presence, and the starting time of the application. A first step including time information and the updated A second step of transmitting a response to another IMPS client device via the IMPS server; and the other IMPS client device that has received the updated presence, the received presence included in the presence, From the application identifier and the time information, the application to be started and the starting time are specified, schedule management for starting the application at the specified starting time is performed, and the application is started at the starting time. 3 steps are included.

[0025] The extended presence information is updated, the updated presence information is transferred to the IMPS client device on the receiving side, the presence information is analyzed, the application to be started and the starting time are identified, and the application is started at the starting time. Is to start. Here, the expanded presence information serves as a message for encouraging some kind of communication from the sending user to the receiving user. Then, the receiving side device reads the intention of the transmitting side user, and the receiving side device automatically performs processing for establishing communication on behalf of the receiving side user.

[0026] Thereby, for example, a chat or video conference by a predetermined member is surely started from a predetermined time, or an e-mail or video reference is reliably received from a communication partner at a desired time. This can be achieved naturally and easily. In other words, from the viewpoint of the user who sends (updates) the presence information, the environmental power S that can be enjoyed in a variety of communication that is optimal and suitable for the situation is realized more easily. become.

[0027] The program of the present invention is for causing the IMP S client apparatus to execute each step of the IMPS providing method of the present invention.

[0028] Improve the data structure of the IMPS service layer, which is the top layer of the IMPS client program, and read and analyze the newly added presence information, manage the schedule, and at the specified time This is a new function that starts the specified application. Schedule management machines and application startups can be easily implemented with less data changes with less processing. As a result, the IMPS client program that received the presence information is specified. It becomes possible to start the specified application at the time of starting.

[0029] Therefore, even if the sender does not make a special action (call), and the receiver does not perform any special device operation to participate in communication in response, the sender side Cooperation between the IMPS client device and the receiving IMPS client device (such as establishing a link for communication) can be automatically realized.

The invention's effect

[0030] According to the IMPS system of the present invention, the potential capabilities of IMPS (Instant Message 'and' Presence Service) are fully extracted from the viewpoint of active use of information by improving the data structure. IMPS functions can be enhanced and the use of IMPS can be diversified.

[0031] Therefore, even if the sender does not make a special action (call), and even if the receiver does not perform any special device operation to participate in communication in response, Cooperation between the IMPS client device and the IMPS client device on the receiving side (such as establishing a link for communication) is automatically realized. As a result, it is possible to greatly save the effort required for each user to communicate.

[0032] For example, a chat or video conference by a predetermined member can be started reliably from a predetermined time, or an e-mail or video letter can be reliably received from a communication partner at a desired time. It ’s natural and easy to do.

[0033] In other words, from the viewpoint of the user who transmits (updates) the presence information, an environment where the user can enjoy a variety of communication that is optimal and suitable for the situation is more easily realized. It will be.

[0034] This contributes to increasing the attractiveness of IMPS and promoting its use.

[0035] In addition, the client device (for example, a mobile terminal) of the present invention is compatible with IMPS, and is not limited to a passive function of information sharing, and realizes communication that makes use of the information. Therefore, it is equipped with more aggressive functions, so that it is possible to increase the functionality and practical value of the device (terminal).

[0036] Further, according to the IMPS providing method of the present invention, for example, a chat or video conference by a predetermined member can be surely started from a predetermined time, or a communication partner can be connected at a desired time. Therefore, receiving e-mails and video letters reliably can be realized naturally and easily.

BEST MODE FOR CARRYING OUT THE INVENTION

First, the difference between the technical idea of the prior art and the technical idea of the present invention will be described. In the following explanation, it is assumed that IMPS is used and user A and user B chat using mobile terminals.

[0043] First, let us consider the procedure when user A and user B chat using mobile terminals using conventional IMPS (instant message 'and' presence service). The procedure in this case is as follows, for example.

Step (1): User A informs User B that he / she is online (presence), thereby sharing common information between User A and User B. Step (2): One of user A or user B calls the other, for example, using e-mail, “Do you want to chat from 0:00?”.

Step (3): In response to the call, the other party responds to the other party, for example, using electronic mail to “agree to chat”.

Procedure (4) User A and user B manage their time.

Step (5) And when the promised time is reached, each of the user A and user B's power S and the chat application installed on their mobile terminal is started and the IMPS server is accessed.

Step (6) A chat room is created in the IMPS server. Then, user A and user B start chatting.

[0044] As described above, even if presence information is shared between user A and user B, the procedure (2) ~ Without step (5), user A and user B cannot communicate.

[0045] In other words, the act of communicating is the first to be realized after the start time is determined in consideration of the circumstances of each person under the agreement of a plurality of users that are not unilateral. In essence, the procedure is cumbersome.

[0046] However, for example, when considering chatting with close friends, one of them has made a commitment in advance that "If you contact me anytime, I will respond to chat immediately". If so, the other person does not need to make an inquiry about whether or not to respond to the chat one by one. Moreover, if the other person can inform the other person of the chat start time by some means, there is no problem in starting the chat from that time. In this case, the procedures (2) to (5) are not necessary.

[0047] The present invention is based on such consideration, expands the format of presence information, adds information on the application to be activated and information on activation time in the client device on the receiving side to the presence information, As a general rule, the receiving client device analyzes the received presence information, and the client program automatically manages the schedule based on the additional information included in the presence information. It automatically launches applications and establishes communication between users.

[0048] In other words, the present invention provides a slight modification to the presence information client program within the range allowed by the standard specification of OMA, and conventionally, the user has manually operated the device to perform the processing. Can be automatically performed on the IMPS system side (network side), so that the burden on the user can be greatly reduced and various communication services can be enjoyed more easily. To do.

Next, an embodiment of the present invention will be specifically described with reference to the drawings.

[0050] (First embodiment)

In the present embodiment, the main features of the present invention will be briefly described.

FIG. 1 is a block diagram for explaining the features of the IMPS (Instant Messaging 'and' Presence Service) system of the present invention, and (a) shows the main configuration of the system. (B) is a diagram for explaining the configuration and operation of the function block included in the IMPS client program on the receiving side.

[0051] As shown in Fig. 1 (a), the IMPS system includes IMPS client devices (hereinafter simply referred to as client devices) 10a and 10b, and IMPS server 30 such as the Internet. Connected via communication line.

[0052] The IMPS client devices 10a and 10b are, for example, mobile phone terminals having a voice over IP function (a function of converting voice into a bucket and communicating via the Internet). IMPS client programs 57a and 57b are installed in the IM PS client devices 10a and 10b.

[0053] As shown on the right side of Fig. 1 (a), in the present invention, the data format of presence information (PRS) is expanded, and additional information DK (that is, an application designating an application to be started) is expanded. Identification information and time information indicating when the application was started).

[0054] Also, the IMPS client programs 57a and 57b of the present invention receive the received presence information.

In addition to a function for analyzing (updated presence information), a function for performing schedule management in cooperation with schedulers 59a and 59b based on application identification information and time information included in the presence information, and an application (for example, , Chat application) 58a and 58b are activated at a designated time.

[0055] Further, the IMPS server 30 includes profile information of users who can receive the IM service and presence service, and a database that stores the presence information of each user (this point is not shown in FIG. 1). (See below with reference to Figure 4).

Hereinafter, the operation of the IMPS system of the present invention will be described.

[0057] As shown in FIG. 1 (a), the user of the IMPS client apparatus 10a updates his / her presence information (step S500). At this time, the updated presence information includes additional information DK (that is, application identification information specifying an application to be started and time information indicating whether the application has been started or not).

[0058] For example, the IMPS server 30 transfers and distributes the updated presence information to other users in real time (step S501). [0059] The IMPS client program 57b installed in the IMPS client device 10b on the receiving side reads the received presence information (PRS), analyzes it, and transmits it from the additional information DK included in the presence information (PRS). The user who wants to start the service knows the application that the user wants to start and its start time, sets the necessary information in the scheduler 59b, and starts the schedule management.

[0060] Then, the user power of the IMPS client device 10b on the receiving side has previously approved the contents of the additional information DK included in the presence information from other users (ie, performs processing depending on the additional information DK). When the designated time is reached, the MPS client program 57b automatically starts an application (here, a chat application) 58b. If the user does not approve the contents of the additional information DK, the user is asked whether or not to approve, and the application (chat application) 58b only if the approval is confirmed. Start up. As a result, the IMPS client device 10b on the receiving side automatically accesses the IMPS server 30, and a communication link for chat is established (step S503).

On the other hand, at the same time, the user of the IMPS client device 10a on the transmission side also accesses the IMPS server 30 using the chat application 58a, and a communication link for chat is established (step S502). As a result, the user of the IMPS client device 10b on the receiving side can participate in the chat without performing a troublesome procedure.

[0062] Next, a characteristic configuration of the IMPS client programs 57a and 57b according to the present invention will be described with reference to FIG.

[0063] As shown in Fig. 1 (b), the service layer (service layer) 100, which is the uppermost layer of the IMPS client program, includes, as functional blocks, a presence analysis unit 71, a schedule management unit 72, and application activation. A unit 73 and an application interface 74.

[0064] The presence analysis unit 71 reads and analyzes the received presence information (PRS), and from the additional information DK included in the presence information (PRS), the application that the transmission side user wants to start and the start thereof The time is grasped, and when the activation time is first, the information of the application and the activation time is passed to the schedule management unit 72. On the other hand, the startup time is In the present case (immediate activation), the presence analysis unit 71 passes information on the application to be activated to the application activation unit 73.

The schedule management unit 72 performs schedule management for automatic application startup in cooperation with the scheduler 59b, and passes information on the application to be started up to the application start-up unit 73 at the start point. The scheduler 59b may have a scheduler function in the schedule management unit 72 itself, which is not essential.

The application activation unit 73 activates the application 58b based on the information passed to the presence analysis unit 71 and the schedule management unit 72.

[0067] Thus, according to the present invention, even if the sender does not make a special action (call), the receiver performs a special device operation in order to participate in communication in response. Even without this, cooperation (such as establishing a link for communication) between the IMPS client device on the sending side and the IMPS client device on the receiving side is automatically realized. As a result, it is possible to greatly save the time and effort required for each user to communicate.

[0104] (Third embodiment)

In the present embodiment, an example of using the IMPS system of the present invention (an example of immediately starting an application in a client terminal on the receiving side) will be described.

[0105] FIG. 10 is a diagram for explaining an example of a usage pattern of the IMPS system. In FIG. 10, parts that are the same as those in the previous drawings are given the same reference numerals.

[0106] In the IMPS system of FIG. 10, one member of a specific group updates presence information, distributes the presence information to other members, and the IMPS application on the receiving client device analyzes the presence information. Based on the application identifier and time information included in the presence information, the chat application is started in real time, which automatically and immediately realizes the state of chatting between members.

[0107] As shown in the figure, four users (A to D) are registered in a user list (not shown in FIG. 10) in the IMP S server 30 as members of a predetermined group. In principle, messages and presence can be exchanged using the mobile phone terminals 10a to 10d that support IMPS. However, in the present embodiment, it is assumed that the following conditions are set for each user (A to D).

(1) That is, the user A transmits information indicating that “the chat is immediately started” in the presence information.

(2) User B is a chat application based on the presence information received from User A. The case has been approved in advance to automatically start the case (automatic approval).

(3) User C does not approve in advance that the chat application is automatically activated based on the presence information received from user A. Therefore, when starting a chat application, it is necessary to present this fact to User C and obtain approval from the user's device operation (manual approval).

(4) User D is not permitted to receive presence information from user A.

[0108] Under such conditions, first, User A adds presence information “Let me chat”, “Chat start time is real time (immediately now)”, and “Gnoles for chatting” "Is a XX group" is added and the presence information is updated (step S101). Immediately after that, the chat application is started and the IMPS server 30 is accessed. Thus, a chat room is formed on the IMPS server 30. Then, it waits for the participation of other members (step S102).

[0109] The updated presence information is transmitted to users B and C of the IMPS server 30 (steps S103-1, S103-2).

[0110] User B automatically participates in the specified group X X chat because automatic response is permitted.

[0111] For user C, since the automatic response is not permitted, the mobile phone terminal 10c asks user C for approval (step S105). If it is approved, it participates in the chat for the designated dul XX (step S106).

[0112] Presence information from user A is not received for user D (step S107).

FIG. 11 is a sequence diagram showing operation procedures of the IMPS server and the client device in the IMPS system of FIG. In FIG. 11, the same steps as those shown in FIG. 10 are denoted by the same reference numerals.

[0114] As shown in the figure, user A updates the presence information (step S101). As shown in the lower left side of FIG. 11, the updated presence information includes receiver information, application information to be activated, and time information (in this case, immediate) indicating the activation point. [0115] The updated presence information is notified to users B and C (see the formats in FIGS. 8 and 9: steps S103-1, 103-2). As shown in the lower right of Fig. 11, the presence notification includes information indicating that the sender is A, that the application to be activated is chat, and that the start time of chat is immediate. .

[0116] For user B, the chat application is automatically started immediately (step S104). For user C, after obtaining confirmation from user C (step S105), the chat application is automatically started (step S106).

[0117] (Fourth embodiment)

In this embodiment, another example of using the IMPS system of the present invention (an example of starting an application after a predetermined time in a client terminal on the receiving side) will be described.

[0118] FIGS. 12 (a) and 12 (b) are diagrams for explaining another example of the usage form of the IMPS system.

(a) is a diagram for explaining presence distribution processing, and (b) is a diagram for explaining automatic activation processing of an application. In FIGS. 12 (a) and 12 (b), parts that are the same as in the previous drawings are given the same reference numerals.

[0119] In the IMPS system in Figs. 12 (a) and (b), one member of a specific group updates presence information, distributes the presence information to other members, and receives the client device of the receiving side. The IMPS application analyzes the presence information and starts the chat application after a predetermined time based on the application identifier and time information included in the presence information, and automatically chats between the members. Actually realized.

[0120] As shown in Fig. 12 (a), four users (A to D) have a user list in IMPS server 30 as members of a predetermined group (not shown in Fig. 12 (a)). In principle, each person can exchange messages and presence with the mobile phone terminals 10a to 10d that support IMPS. However, in the present embodiment, it is assumed that the following conditions are set for each user (A to D).

(1) That is, the user A transmits information indicating that “the chat is immediately started” in the presence information. (2) User B approves in advance that the chat application is automatically activated based on the presence information received from user A (automatic approval).

(3) User C has not approved in advance that the chat application is automatically activated based on the presence information received from user A. Therefore, when starting a chat application, it is necessary to present this fact to User C and obtain approval from the user's device operation (manual approval).

(4) User D is not permitted to receive presence information from user A.

[0121] Under these conditions, as shown in Fig. 12 (a), user A first wants to chat in the presence information, and the chat start time is 8:00 pm And the presence information is updated by adding the information that “the group subject to chat is a XX group”. Step ST21). Then, it waits until 8 pm (step S22).

[0122] The updated presence information is transmitted to the user B and the user C of the IMPS server 30 (steps S23-1, S23-2).

[0123] Since user B is allowed to respond automatically, user B performs schedule management in order to automatically participate in the specified group XX chat (ST24).

[0124] Since the automatic response is not permitted for user C, mobile phone terminal 10c requests approval from user C (step ST25). If approved, schedule management is executed to participate in the chat of the specified group XX (step ST26).

[0125] Presence information from user A is not received for user D (step ST27).

[0126] When two hours have elapsed, as shown in Fig. 12 (b), the chat application is activated in each of the mobile phone terminals 10a to 10c of the users A, B, and C, and each mobile phone Terminals 10a to 10c: 10c accesses the IMPS server 30 all at once (ST28_1, 28-2, 28-3). A chat room is formed on the IMPS server 30 at the earliest access timing, and chatting is started.

FIG. 13 shows an IMPS server and client device in the IMPS system of FIG. It is a sequence diagram which shows the operation | movement procedure. In FIG. 13, the same steps as those shown in FIGS. 12 (a) and 12 (b) are denoted by the same reference numerals.

[0128] As shown, user A updates presence information (step ST21). The updated presence information includes receiver information, application information to be activated, and time information indicating the activation time (in this case, 2 hours later), as indicated by a dotted line on the left side of FIG. included.

[0129] The updated presence information is notified to the users B and C (see the formats in FIGS. 8 and 9: steps S23_l and 23-2). In the presence notification, as indicated by the dotted line on the right side of Fig. 13, the sender is A, the application to be activated is chat, the chat start time is 2 hours later, Is included.

[0130] User B's mobile phone terminal 10b registers in the scheduler that the chat application is activated after 2 hours, and starts schedule management (step ST42).

[0131] Further, in the mobile phone terminal 10c of the user C, after obtaining the confirmation of the user C (step St

44) Register in the scheduler that the chat application launch time is 2 hours later, and start schedule management (step ST45).

[0132] After two hours, the mobile phone terminals 10a to 10c start the chat application all at once and access the IMPS server 30 (ST28-1, 28-2, 28-3). This initiates a chat between users A-C.

[0133] ( ^Fifth Embodiment)

FIG. 14 is a block diagram for explaining the characteristic configuration of the client device in the IMPS system of the present invention and the procedure for updating and distributing the presence information. The basic configuration shown in FIG. 14 is the same as that of FIG. 1, and the same reference numerals are given to the portions common to FIG. 1 and the previous drawings.

As shown in the figure, the mobile phone terminals 10a and 10b as IMPS client devices include transmission / reception units 50a and 50b, IMPS client programs 57a and 57b, chat applications 58a and 58b, a scheduler 59a, 59b.

[0135] In the mobile phone terminal 10a that transmits the presence information, the IMPS client product 57a registers the activation time (starting time) of the chat application in scheduler 58a (step ST11). Thereafter, the updated presence information is transmitted via the transmission / reception unit 50a (step ST12, step ST13).

[0136] Upon receiving the updated presence information from user A, IMPS server 30 updates the presence information related to sender A stored in presence information storage unit 37 (see Fig. 4).

[0137] Next, the IMPS server 30 transmits presence information (presence notification: see the formats in Figs. 8 and 9) to the mobile phone terminal 10b of the user B (step ST14).

[0138] Presence information (presence notification) received by the transmitting / receiving unit 50b of the mobile phone terminal 10b is passed to the IMPS client program 57b (ST15). The IMPS client program 57b analyzes the passed presence information and recognizes the activation target application and the activation time.

[0139] When the IMPS client program 57b determines that schedule management is necessary from the startup time information, the IMPS client program 57b registers the startup time (startup time) information in the scheduler 59b and performs schedule management (step ST16). .

FIG. 15 is a block diagram for explaining an operation at the time of application activation in the IMPS system of the present invention shown in FIG. The basic configuration shown in FIG. 15 is the same as that of FIG. 1, and the same reference numerals are given to the portions common to FIG. 1 and the previous drawings.

[0141] In the mobile phone terminals 10a and 10b of the users A and B, the schedulers 59a and 59b notify the IMPS client programs 57a and 57b when the application activation time comes (step ST51 (a), step ST51 (b)).

[0142] Next, the IMPS client program 57a, 57b starts the application 58a, 58b (step ST52 (a), step ST52 (b)), and then sends the IMPS server 30 to the transmitting / receiving units 50a, 50b. (Step ST53 (a), step ST53 (b)). The transmission / reception units 50a and 50b access the IMPS server 30 (step ST54 (a), step ST54 (b)). A chat link is established.

[0143] As described above, according to the present invention, the presence information and the client program are slightly modified within the range permitted by the standard specification of 〇MA, and conventionally, the user manually operates the device. The IMPS system side (network side) can automatically perform the processing that has been performed, which greatly reduces the burden on the user, and each user has a variety of communication functions. You will be able to enjoy the Chillon service more easily. Note that the present invention is not limited to the above-described embodiment, and various modifications and applications are possible. For example, the automatic activation of an application can select automatic approval / manual approval for each user or group. In addition, the presence information can include various information in addition to the information on the application to be activated and the information on the activation time. For example, the application to be launched can include information specifying more than one function, and which of these functions can be used. In addition, in the case where an external device is controlled via an activated application, a control signal (signal for instructing control contents) of the external device can be included in the presence information.

[0144] As described above, according to the IMPS system of the present invention, IMPS (Instant Message 'and' Presence Service) possesses from the viewpoint of active use of information by improving the data structure. Potential capabilities can be fully exploited, IMPS functions can be enhanced, and IMP S usage forms can be diversified.

[0145] Therefore, even if the sender does not make a special action (call), and even if the receiver does not perform any special device operation to participate in communication in response, Cooperation between the IMPS client device and the IMPS client device on the receiving side (such as establishing a link for communication) is automatically realized. As a result, it is possible to greatly save the effort required for each user to communicate.

[0146] For example, a chat or video conference by a predetermined member is surely started from a predetermined time, or an e-mail or video letter is reliably received from a communication partner at a desired time. It ’s natural and easy to do.

[0147] In other words, from the viewpoint of the user who sends (updates) the presence information, an environment where the user can enjoy a variety of communication that is optimal for him / her in the current situation can be realized more easily. It will be.

[0148] This contributes to increasing the attractiveness of IMPS and promoting its use.

[0149] Further, the client device (for example, portable terminal) of the present invention is compatible with IMPS and has information. It is equipped with a more aggressive function that realizes communication that vibrates the information, not just sharing and reviewing information, and thus enabling multifunctional devices (terminals) Improves practical value.

[0150] Further, according to the IMPS providing method of the present invention, for example, a chat or a video conference by a predetermined member is surely started from a predetermined time, or an e-mail or video is transmitted from a communication partner at a desired time. Receiving a letter reliably can be realized naturally and easily.

[0151] Further, in the present invention, the data structure of presence information is improved within the allowable range in the specification, and the presence information includes the identification information of the application to be activated and the information of the activation time. Make it possible. By expanding this presence information, the presence information contributes to actively encouraging participation in communication with other parties that are not just passive type information (conventional information). Type information will also be added. Therefore, with a simple improvement, the use value and use range of IM PS can be significantly improved compared to the past.

[0152] In the present invention, the data structure of the IMPS service layer, which is the top layer of the IMPS client program, is improved, and newly added presence information (application identifier and time information) is read and analyzed to manage the schedule. It is possible to launch the specified application with the user's approval. As a result, the specified client application can automatically start the specified application at the start point specified by the received presence information. Therefore, with a simple improvement, the value and range of use of IMPS can be significantly improved compared to the past.
