Description

  The present invention relates to a service support system that provides an auxiliary function for improving the convenience of a service in a network service that provides a service to a user via a network. It is about the system which recommends the use of.

  When a service provider recommends the use of a service to a user, there are roughly two types. One is performed for an unspecified number of users before the user uses the service for the first time, and the other is to prompt the user to restart the service when the user interrupts the service after starting to use the service. . The present invention relates to the latter.

  In the latter case, it is clear that a user who has used the service once has a certain degree of interest compared to the former case, and is expected to have a relatively high recommendation effect. From the service provider's point of view, this leads to an increase in the revisit rate of users. From the user's point of view, there is a case in which a certain service is used and the service is forgotten to be resumed after being temporarily interrupted on the assumption that it will be resumed later. By recommending service use (continuation / resumption) from the service side, a reminder is provided to the user, which leads to improvement of user convenience.

  As a conventional technique for the latter related to the present invention, a user is registered with a contact address such as an e-mail address at the time of user registration, and a message recommending service use is transmitted to a registered e-mail address according to the user's service use situation. It is common to do. For example, if the service of Non-Patent Document 1 does not log in to the service for a certain period, the service is notified to the user by e-mail that the service has not been used recently. In addition, information (trigger information) that can identify a restart method for the system to restart the service is embedded in the e-mail body, and the user specifies the trigger information to the system ( For example, you can easily restart the service by clicking the displayed trigger information. By transmitting the trigger information for starting the service together with the notification, the number of user operations from receiving the notification to restarting the service is reduced as much as possible.

  As notification means other than e-mail, Instant Messaging (IM), a mobile phone short message service (SMS), or the like may be used.

  The idea of sending notifications for prompting service restart and trigger information to a user can be applied to various services. However, the conventional technology is premised on a web service on the Internet that is operated and browsed by a web browser on a personal computer, and there is a problem when assuming a service that uses more advanced functions on a plurality of terminals having different capabilities. .

  The conventional technology does not consider whether or not the service can be executed on the notified terminal. As for the service executed by the Web browser, this is not a problem because the Web browser absorbs the difference in capability of each terminal to some extent. However, for example, the video playback software must be started for a service that distributes a specific type of video. If it is necessary, in a terminal in which necessary software is not installed, the service cannot be resumed when the trigger information is referred to.

  Furthermore, personal computers and other terminals with various specifications have recently become widespread, and mobile phones are equipped with means for receiving notifications such as e-mails. In such a situation where there are a plurality of terminals having different capabilities, it is conceivable that the screen size and processing capability are insufficient to execute the service on the notified terminal. The conventional technology does not consider the difference in capability of each terminal as described above.

  Also, even if the terminal capability is sufficient to execute the service, depending on the user's intention and the situation at that time, there may be a desire to execute the service on a terminal different from the terminal that received the notification is assumed. For example, it is possible to receive a notification from a mobile phone and execute the service with a Web browser of the mobile phone, but want to receive the service on a personal computer at home because you want to see the video displayed there in more detail there is a possibility. In such a case, the received notification and trigger information are not meaningless for the user, and troubles such as transferring the trigger to a terminal where the user wants to receive the service are generated.

  The present invention has been made in view of such problems, and an object of the present invention is to transmit service restart trigger information that can easily restart a service to a terminal that can restart a suspended service.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration of a network system according to a first embodiment of the present invention. The network system of the present invention includes a service support system 10, a service providing system 20, and a terminal system 40. The service support system 10 includes a context collection unit 11, a context management unit 12, a terminal information management unit 13, A service information management unit 14 and a notification transmission unit 15 are provided.

  In a situation where the service providing system 20 provides a service to the terminal system 40 via the communication system 30, an operation of the user 50 using the terminal system 40, a result of processing in the service providing system 20, or A situation is assumed in which the service is interrupted due to a system failure or the like, and a notification is sent to the user 50 prompting the user to restart the service.

The context collection unit 11 detects service interruption, service identification information for identifying the interrupted service type from some or all of the service providing system 20, the communication system 30, and the terminal system 40, and the interruption. User identification information for identifying the user 50 who has used the service is collected, and context information including them is transmitted to the context management unit 12.
The context management unit 12 holds context information and transmits context information to the notification transmission unit 15.
The terminal information management unit 13 holds terminal capability information related to the capability of the terminal system 40 that allows the user to receive the service restart notification according to the present invention in association with the user identification information.
The service information management unit 14 holds service request information describing the capability required of the terminal system 40 for executing the service and service resumption trigger information describing a procedure for resuming the interrupted service.
The notification transmission unit 15 acquires context information from the context management unit 12. Based on the user identification information described in the context information, terminal capability information is acquired from the terminal information management unit 13 for each terminal system 40 that is a candidate for notification transmission to the user. Further, the service information management unit 14 acquires service request information and service resumption trigger information for a service corresponding to the service identification information described in the context information. The obtained service request information and terminal capability information are compared, a terminal system 40 having a capability necessary for executing the service is selected, and service resumption trigger information is provided to the selected terminal system 40 by a given communication means. Send.

  The service support system 10 based on the above configuration can selectively send a notification prompting the user to restart the service and trigger information for restarting the service to the terminal system 40 that can restart the service.

Next, the operation of the service support system according to the first embodiment will be described with reference to FIG.
A situation is assumed in which the service providing system (S) 20 provides a video distribution service to the user (X) 50 via the communication system 30 and the terminal system (A) 40. The service providing system (S) 20 is considered to hold information necessary for executing the service as shown in Table 1.

  In this state, when the video delivery service is interrupted by the operation of the user (X) 50, the service providing system (S) 20 includes the service with the service ID1 being provided corresponding to the interrupted service among the information in Table 1. The type and user ID are notified to the context collection unit 11 of the service support system 10 of the present invention.

  The context collection unit 11 transmits the service type received from the service providing system (S) 20 to the context management unit 12 as service identification information and the user ID as user identification information. Information transmitted to and held at the context management unit 12 at this time is called context information, and Table 2 shows an example thereof.

In the first embodiment, the playback position of the distribution video shown in Table 1 is included in the context information as service status information as shown in Table 2, and the service is resumed after restoring the service execution status. It is an example.
Further, in the first embodiment, since a notification to the user is periodically transmitted, a registration time that is a time when the context information is transmitted to the context management unit 12 in the context information. And the previous notification time.
In the first embodiment, the service identification information includes an ID for uniquely identifying the service providing system (S) 20 in the service support system 10, and the interrupted service unique in the service providing system (S) 20. Includes an ID for identification. This is because the service support system 10 is assumed to be used from a plurality of service providing systems. For the same reason, the user ID used by the service providing system may be different between the service providing systems. In the first embodiment, the user ID in the service providing system (S) 20 and the user identification information held by the context management unit 12 match, but the user ID in each service providing system and the service support system are internal. In some cases, a function for converting the user identification information used in the process is required.

  The notification transmission unit 15 acquires a list of context information shown in Table 2 from the context management unit 12. Next, the notification transmission unit 15 inquires of the terminal information management unit 13 about the terminal system 40 that can be used for notification to the user by using the user identification information described in each context information as a key. An example of information of the terminal system 40 held by the terminal information management unit 13 is shown in Table 3.

  Table 2 describes user identification information “user_X”. When the terminal system corresponding to “user_X” is examined from the user identification information column of Table 3, the three lines from the top correspond to these terminal systems. (A), the terminal system (B), and the terminal system (C) are extracted as candidate terminal systems to be notified to user_X.

  Next, the notification transmitting unit 15 searches for service request information in which functions required for the terminal system 40 are described when providing the service, using the service identification information described in the context information as a key. Table 4 shows an example of service request information held by the service information management unit 14.

  The service identification information “Service Providing System S: Movie_1” is obtained from the context information in Table 2, and the service request information corresponding to this is described in the first and second lines of Table 4.

When comparing the terminal capability information and the service request information obtained in this way, the terminal system (A) 40 is compatible with both types of service request information, and the terminal system (B) 40 is described in the second line. It can be seen that “flv, 1 Mbps” is satisfied.
Through the above processing, the notification transmission unit 15 can select the terminal system (A) 40 and the terminal system (B) 40 as terminal systems that can restart the service.

  A notification can be transmitted to either or both of these two types of terminal systems. In the first embodiment, it is assumed that the terminal system (B) 40 is selected. As an example of a method for transmitting a notification to the terminal system (B) 40, it is conceivable that a list of destinations is held for each terminal as shown in Table 3.

  In Table 3, since the destination of the terminal system (B) 40 is “im: userX@192.168.1.2”, the IM of the terminal system with the IP address 192.168.1.2 (Instant Messaging) The notification content is transmitted as a message for user_X to the service port.

  In this way, the transmission destination of the notification is determined, and the notification transmission unit 15 needs to determine the notification content to be transmitted. The notification content includes service restart trigger information that is interpreted by the terminal system that is the notification transmission destination and is necessary for the terminal system to perform the service restart process. According to Table 4, service resumption trigger information corresponding to service request information “flv, 1 Mbps” determined to be compatible with the terminal system (B) 40 is “http://www.service_s.co.jp/movie_1.flv”. "

Although it is conceivable that the service restart trigger information obtained in this way is included in the notification contents as it is, in the first embodiment, as described above, the service status information in Table 2 is also transmitted. In the context information shown in Table 2, service state information is described as “the 1234th frame”, and a method of adding the numerical value of 1234 to the end of the service restart trigger information and transmitting it can be considered. For example, “http://www.service_s.co.jp/movie_1.flv?offset=1234”. As a result, it is possible to include the service status information necessary for resuming the service after restoring the service in the interrupted state in the notification content.
In addition, the notification content can include a sentence that is written in a natural language and is intended to be read by the user, and that prompts the service to be restarted. In the first embodiment, the sentence is omitted.

  There are various timings for the notification transmitter 15 to transmit the notification, but in the first embodiment, periodic transmission is assumed. When the elapsed time up to the current time exceeds the predetermined notification interval starting from the previous notification time or the registration time in the case of the first notification described in the context information shown in Table 2, the context information Periodic transmission is possible, for example, by trying to send a notification regarding the message. In addition to periodic notifications, notifications when there is a request from the service providing system 20, when the user 40 activates the terminal system 40, or the user status in the terminal system 40 (eg, login status, presence) ) May change when the change occurs.

  The above is the operation of each component of the service support system according to the first exemplary embodiment of the present invention. An example of a terminal system that operates in cooperation with the service support system is described below. The destination terminal system (B) 40 receives a message “http://www.service_s.co.jp/movie_1.flv?offset=1234” from the notification transmission unit 15. The message part is recognized as a URI (Uniform Resource Identifier) by IM (Instant Messaging) software of the terminal system (B) 40 and displayed as a clickable link on the display screen of the IM software. Normally, when such a URI is clicked, an appropriate video playback software is started via the web browser software, and the user 50 clicks this link to stop the service once in a few steps. Can be resumed. Further, the portion of “offset = 1234” in which the service status information is embedded is interpreted by the service providing system 20 so that the reproduction can be resumed from the reproduction position at the time of interruption, and the user (X) 50 The trouble of restarting the service, such as fast-forwarding to where it has already been viewed, can be eliminated.

Next, as a method for obtaining information held by the service support system in the present embodiment, the table shown in Table 4 held by the service information management unit 14 is static information that does not change frequently. A method is assumed in which information is obtained from the operator of the service providing system 20 and manually registered in the system.
On the other hand, the information in Table 3 held by the terminal information management unit 13 dynamically changes depending on the situation such as whether or not the terminal system is activated. For example, by using a mechanism that allows the terminal system to register its own state with the server, such as SIP (Session Initiation Protocol) described in Non-Patent Document 2, the terminal activation status and the like are displayed in real time in the table shown in Table 3. Can be reflected.

  In this embodiment, the context collection unit 11 collects information such as a user ID that is the source of context information from only the service providing system 20, but when collecting from the communication system 30, for example, the service providing system 20 and the terminal Collecting flow information grasped by a router device that mediates communication of the system 40, session information grasped by a SIP server or the like that instructs other communication devices to start a communication session between the service providing system 20 and the terminal system 40 Can be considered. Since both the flow information and the session information can include the addresses of the service providing system 20 and the terminal system 40, the service support system 10 holds the association between the address information and the service providing system 20 and the terminal system 40. It is possible to grasp which terminal system is receiving the service. With regard to collecting context information from the terminal system 40, it is conceivable to collect the internal state of client software executing services on the terminal system 40.

  The service interruption targeted by the present invention is expected not only by one session or transaction interruption such as interruption of a series of information transfer shown in this embodiment, but also by a service provider who provides the service. Refers to general stagnation in user behavior in one-way or bifurcation sequences. For example, it includes a case where there is no use after a user registers for a certain service, or a case where a user does not lead to purchase behavior after registering a product in a “shopping cart” at a shopping site.

  FIG. 2 is a diagram showing the configuration of the service support system according to the second embodiment of the present invention. The service support system 60 illustrated in FIG. 2 includes a preference information management unit 16 that manages preference information indicating user preferences regarding what terminal system the service is to be resumed, and the terminal system in the notification transmission unit 15 By adding preference information to the selection criterion, it is possible to solve the problem that the user's intention regarding which terminal system receives the service in the prior art cannot be reflected.

Here, only the difference from the first embodiment shown in FIG. 1 will be described.
The preference information management unit 16 holds preference information of the user 50. Table 5 shows an example of information held by the preference information management unit 16.

As in the first embodiment shown in FIG. 1, the notification transmission unit 15 uses the information from the terminal information management unit 13 and the service information management unit 14 to select a terminal system that can provide a service. As a result, it is assumed that the terminal system (A) 40 and the terminal system (B) 40 are selected as in the above-described embodiment.
The notification transmission unit 15 sends a user (X) from the preference information management unit 16 for a service whose service identification information is “service providing system S: movie_1”, to which a notification is sent from the preference information management unit 16. ) Get 50 preference information. According to Table 5, it can be seen that the content is desired to be provided with high quality. As described in the first embodiment, from Tables 3 and 4, when the service is resumed for the terminal system (A) 40, the bit rate is 8 Mbps, and for the terminal system (B) 40 is 1 Mbps. In this case, the terminal system (A) 40 is selected.
In this way, the service support system 60 shown in FIG. 2 makes it possible to restart the service with the terminal system reflecting the user's wishes.

  There are several examples of means by which the preference information management unit 16 obtains preference information. First, it is conceivable that the user's personal preference information is registered in the service providing system 20 at the beginning of the service subscription, and the preference information management unit 16 collects the preference information. Alternatively, when the user interrupts the service, the preference information is specified and then interrupted, and the preference information is transmitted to the preference information management unit 16 via the service providing system 20 or the terminal system 40. Can be considered. Alternatively, once the notification is transmitted, trigger information for registering the preference information is included in the notification content, and the user registers the preference information in the preference information management unit 16 using the trigger information. Examples are also conceivable.

  FIG. 3 is a diagram showing a configuration of a service support system according to the third exemplary embodiment of the present invention. The service support system 70 shown in FIG. 3 includes a presence information management unit 17 that acquires and manages presence information representing the status of the user 50 in the terminal system 40, and the notification transmission unit 15 includes service request information, Based on the terminal capability information and the presence information of the user 50 provided by the presence information management unit 17, the user 50 selects the terminal system 40 that is predicted to be more appropriate for receiving the notification. .

Here, only the difference from the first embodiment shown in FIG. 1 will be described.
The presence information management unit 17 collects the presence information of the user 50 from each terminal system 40 by the method described in Non-Patent Document 3. Table 6 shows an example of information held by the presence information management unit 17 as a result of collection.

As in the first embodiment shown in FIG. 1, the notification transmission unit 15 uses the information from the terminal information management unit 13 and the service information management unit 14 to select a terminal system that can provide a service. As a result, it is assumed that the terminal system (A) 40 and the terminal system (B) 40 are selected as in the above-described embodiment.
The notification transmission unit 15 acquires presence information of the user 50 in the terminal system (A) 40 and the terminal system (B) 40 from the presence information management unit 17. According to Table 6, the terminal system (A) 40 is “being away”, the terminal system (B) 40 is “contactable”, and it is predicted that it is appropriate to send a notification to the terminal system (B) 40. Is done. As a result, the terminal system (B) 40 is selected as the notification transmission destination. The subsequent processing is the same as in the above-described embodiment.

  FIG. 4 is a diagram showing a configuration of a service support system according to the fourth exemplary embodiment of the present invention. The service support system 80 shown in FIG. 4 converts the information that the service providing system 20 transmits to the terminal system, and even in a terminal system that lacks the capability required to execute the service. A transcoding unit 19 that enables execution, and a transcode information management unit 18 that holds transcoding information that is a pair of service request information and terminal capability information that can be converted by the transcoding unit 19 and transmits the transcoding information to the notification transmission unit 15 The notification transmission unit 15 selects the notification transmission destination terminal system in addition to a terminal system having a terminal capability that satisfies the service request information acquired from the service information management unit 14, and transmits the transmission request to the service request information. Corresponds to transcoded service request information obtained by applying code information It is characterized in that selecting a terminal system having a terminal capability.

Here, only the difference from the first embodiment shown in FIG. 1 will be described.
In the present embodiment, the terminal information management unit 13 holds the information in Table 7, and the service information management unit 14 holds the information in Table 8.

When the notification transmitting unit 15 acquires service request information necessary for the suspended service described in the context information of Table 2 from Table 8, and searches the terminal system of the user (X) 50 having the corresponding terminal capability from Table 7, As a result, the corresponding terminal system does not exist.
Here, referring to the transcode information in Table 9 held by the transcode information management unit 18, when the transcode unit 19 whose transcoder identification information is 1 is used, the file type “wmv” included in the service request information is changed. It can be seen that the terminal system (B) 40 can convert to “flv”, and the bit rate can be converted to “2 Mbps” or less, which is the performance limit of the terminal system (B) 40. As a result, it is understood that the service can be restarted by the terminal system (B) 40 by using the transcoding unit 19.

  From these results, the notification transmitter 15 transmits a notification to the terminal system (B) 40. Since the transcoding unit 19 needs to mediate the notification content, the URI for using the transcoding unit 19 is “http://transcode.sss.co.jp/?id=transcoder identification information & ft = file Assuming the type & br = bit rate & sp = original URI of the service providing system, the notification content is “http://transcode.sss.co.jp/?id=1&ft=wmv&br=2 Mbps & sp = http: // /Www.service_s.co.jp/movie_1.flv?offset=1234 ”. The terminal system (B) 40 that has received this accesses the transcoding unit 19 shown at the beginning of the URI, similarly, when the user 50 clicks. The transcoding unit 19 interprets the “?” Transition of the URI, executes the appropriate transcoding unit 19, acquires information from the service providing system 20, converts it, and transmits it to the terminal system (B) 40. .

  In addition, although the 2nd-4th Example was demonstrated separately as mentioned above, this invention can also combine 2 or more of each of the 2nd-4th Example.
