Method and device for changing the presence information

The present invention relates to an IMS service, and more particularly, to a method and apparatus for reservation change of presence information in an IMS-based service.

With the development of technology that combines voice call and data communication, as a variety of communication environments are provided, the presence system that informs mobile subscribers of network access and status information has emerged as a basic service that meets new communication service needs. It was.

Presence system provides subscribers with online status, access method, and status information of subscribers, enabling more efficient Voice over IP (VoIP), video calling, and instant messaging services. Make it easy for subscribers to understand their situation.

Session Initiation Protocol (SIP) is adopted to implement such a presence system. SIP is an application level protocol that can guarantee the mobility of the subscriber because the session is connected by the same identifier (identifier).

Therefore, it is possible to check the location of online subscribers based on SIP and to provide current status information of buddy, which is another user who can communicate.

Currently, in the case of an IM (instant messaging) service, there is a problem in that a corresponding service must be accessed in order to update the presence information (more detailed state information).

The present invention is to provide a method and apparatus for changing the presence information that can change the presence information without accessing the IM service.

In addition, the present invention is to provide a method and apparatus for changing the presence information that can change the presence information according to the schedule of the user.

According to one aspect of the present invention, a method for changing the presence information is provided.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting of the present invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this application, the terms "comprise" or "have" are intended to indicate that there is a feature, number, step, operation, component, part, or combination thereof described in the specification, and one or more other features. It is to be understood that the present invention does not exclude the possibility of the presence or the addition of numbers, steps, operations, components, components, or a combination thereof.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The presence server according to the present invention may change the presence information of the terminal regardless of whether the terminal is connected according to the received reservation information.

In this specification, for convenience of understanding and explanation, the presence server receives the presence reservation information from the terminal and changes the presence information, and receives the schedule information from the mail server and changes the presence information. Let's do it. That is, in the present specification, although reservation information is used as divided into presence reservation information or schedule information below, it should be understood that each of the reservation information refers to reservation information.

First, the configuration of the IMS presence service will be briefly described to facilitate understanding and explanation.

1 is a diagram illustrating a configuration of an IMS presence service according to an embodiment of the present invention.

Presence information herein refers to the user's IMS service connection status (e.g., online, idle, away, busy, meal, It will be defined as a variety of personal information, including meetings (lesson), etc.).

In addition, the presence information may be used in various meanings as well as personal information of the user, as well as environment information necessary for driving the IMS service, element information required by various applications provided by the IMS service, and the like. Such presence information may be generated based on XML according to a MIME type and provided to each terminal.

In addition, according to the nature of the presence information, there are two main methods of delivering the corresponding presence information to the presence server.

Presence information is valid only when the IMS service is connected, and information that is not valid when the connection is terminated (Soft-state Presence information) is transmitted through the Session Initiation Protocol (SIP) interface (using the Publish method). Status information (e.g. online, away, eating, busy)

On the other hand, the information (Hard-state Presence information) that is not dependent on the user's IMS service access and is maintained until the user's change is transmitted through the XML Configuration Access Protocol (XCAP) interface. This includes information such as telephone numbers and addresses.

The presence server collects soft-state and hard-state presence information from the first terminal 120 and transmits the soft-state and hard-state presence information to the terminals registered in the buddy list corresponding to the first terminal 120.

2 is a flowchart illustrating a process of transmitting presence information to a first terminal through a SIP interface according to an embodiment of the present invention.

The information transmitted to the first terminal 110 through the SIP interface is valid only when the IMS service is connected and is soft-state information that is lost when the connection is terminated as described above.

First, the second terminal 120 transmits a "PUBLISH" message to the presence server through the IMS core, and the "PUBLISH" message includes state information of the second terminal 120. The presence server that has received the message "PUBLISH" sends a "200 OK" response of acknowledgment to the second terminal 150 through the IMS core to inform that the processing for "PUBLISH" is completed.

Thereafter, the presence server transmits a "NOTIFY" message including the state information of the second terminal 120 to the first terminal 110 through the IMS core.

3 is a flowchart illustrating a process of transmitting presence information to a first terminal through an XCAP interface according to an embodiment of the present invention.

As described above, the information transmitted to the first terminal 110 through the XCAP interface is hard-state information maintained until the change of the user regardless of the IMS service access.

First, the second terminal 120 generates hard-state information (for example, its own group list, user permission information on presence information, etc.) in the PIDF format through the XCAP interface to generate an XML Data Manipulation Server (XDMS). Register at

Thereafter, the XDMS transmits a "NOTIFY" message including hard-state information of the second terminal 120 to the presence server, and the presence server delivers a "NOTIFY" message to the first terminal 110.

Hereinafter, in the present specification, the presence information should be understood to mean not only soft-state information but also hard-stat information.

4 is a diagram illustrating presence information according to an embodiment of the present invention.

Presence information refers to information representing various personal information including a user's IMS service connection status. In addition, the presence information may be defined as various types of information such as environment information necessary for driving an IMS service and element information required by various applications of a communicator. The presence information may also be written in an XML based language of a MIME type as described above.

As shown in FIG. 4, the presence information may include location information, access information, and status information of the user.

The location information is information indicating a point where the terminal is currently located, and may include country and state / region region information. Location information may be obtained using cell information of the base station.

In addition, the connection information is information indicating whether the terminal of the current user is connected to the IMS service. For example, the connection information may be in an active state or an idle state.

The status information is information indicating the current status of the user by the user's selection and the terminal of the current user connected to the IMS service. As described above, the state information is valid only when the IMS is in service and is soft-state presence information that loses validity when the connection is terminated.

For example, the status information can be any of away, busy, meal, meeting or not. Of course, the status information may include other states (for example, vacation, business trip, etc.).

5 is a block diagram showing an internal functional configuration of a presence server according to an embodiment of the present invention.

As shown in FIG. 5, the presence server 500 according to the present invention includes a data transceiver 510, a state manager 515, a buddy manager 520, a database 525, and a controller 530. .

The data transceiver 510 is coupled with a plurality of terminals and other servers through a communication network to perform a function of transmitting and receiving data.

For example, the data transceiver 510 receives the presence reservation information from the terminal. Here, the presence reservation information includes access information or status information and time information. That is, the presence reservation information may include connection information indicating an active or non-accessing idle while the user is accessing the IM service, or status information indicating the user's state. However, hereinafter, for convenience of understanding and explanation, the connection information or state information included in the presence reservation information will be collectively described as the target state information.

In addition, the data transceiver 510 may transmit the presence information to a terminal of another user. Presence information is transmitted over a SIP-based or XCAP-based interface as described above.

The state manager 515 manages the access information and the state information of the subscriber by using the presence information of each subscriber received through the data transceiver 510. In addition, if the presence reservation information is received through the data transmission / reception unit 510, the state manager 515 registers by changing the state information of the subscriber with the target state information when the reservation time is reached. The state manager 515 may generate the presence information including the changed state information and transmit the presence information to a terminal of another subscriber who shares the presence information with the corresponding subscriber.

For example, assume that the target status information is idle and the time information is "4 o'clock". The state manager 515 may forcibly change the subscriber's access information to an idle at the time of four o'clock. As such, when the connection information is forcibly changed, it is natural that the presence server 500 may forcibly release the connection of the terminal corresponding to the subscriber.

For example, the status manager 515 may obtain, from the buddy manager 520, list information of buddies corresponding to the subscriber (that is, list information of other users sharing the presence information).

The buddy manager 520 manages a list of buddies set according to the subscriber. That is, the buddy manager 520 manages each buddy list set as a contact and a service policy of the buddy.

The database 530 stores information about each subscriber, presence information of each subscriber, and the like.

The control unit 530 is the internal functional configuration of the presence server 500 according to the present invention (for example, data transmission and reception unit 510, state management unit 515, buddy management unit 520, database 520, etc.) It performs the function of controlling.

6 is a flowchart illustrating a method of changing a presence information by a presence server according to an embodiment of the present invention. Each step described below is performed by each internal component of the presence server 500, but will be collectively described as a presence server for the convenience of understanding and explanation.

In operation 610, the presence server 500 receives the presence reservation information from the terminal.

For example, a user sets status information on when he / she is expected to be unable to access the IM service, and then creates a presence reservation information including the status information and time information, and the presence server (eg, 500).

In operation 615, the presence server 500 determines whether time information is not included in the received presence reservation information or whether the time information included in the presence reservation information is earlier than the current time.

If the time information is not included or before the current time, in step 620, the presence server 500 immediately registers by changing the state information of the subscriber of the terminal with the target state information included in the presence reservation information.

Here, if the target state information includes the state information indicating the termination of the connection of the terminal, the presence server 500 may forcibly terminate the connection of the terminal being connected.

However, if the time information is not included or not before the current time, at step 625 the presence server 500 determines whether the reservation time has been reached.

For example, the presence server 500 may extract time information included in the presence reservation information and compare the current time with the current time, and determine that the reservation time has been reached if there is a time difference within the same value or within a threshold.

If it is determined that the reservation time has been reached, the presence server 500 registers by changing the status information of the subscriber using the target status information in step 630.

In operation 635, the presence server 500 checks whether other users who share the presence information are connected. Here, the presence server 500 may check whether other users who share the presence information are connected at predetermined time intervals, and when the presence information is received from each subscriber, the presence information of each subscriber ( That is, status information and connection information) can be changed and updated.

In operation 640, the presence server 500 transmits the changed presence information to other users who are connected.

As such, when the user is expected to be unable to access the IM service, the status information of the user may be reserved and then changed by the presence server 500 to be transmitted to other users. As a result, there is an advantage that can prevent misunderstanding due to the non-response to the conversation request of other users.

7 is a diagram illustrating a system that can change the presence information according to another embodiment of the present invention.

As shown in FIG. 7, the system 700 capable of changing the presence information according to the present invention includes a terminal 710, a schedule server 720, and a presence server 500.

The terminal 710 is a terminal that can access an IM service through a communication network. For example, the terminal 710 may be a mobile communication terminal, a notebook computer, a PDA, or the like.

The schedule server 720 is a server that registers / stores and manages a schedule input by a user. For example, the schedule server 720 may be an Outlook server, but is not necessarily limited thereto. That is, in addition to the Outlook server, it includes all devices capable of storing and managing schedule related information in a wired or wireless environment.

The schedule server 720 is coupled to the presence server 500 through a communication network, and transmits schedule information registered by the user to the presence server 500. Here, the schedule information may include time information about each schedule.

In the present specification, it is assumed that the schedule server 720 transmits the schedule information to the presence server 500. However, the description will be mainly focused on the schedule server 720. However, the terminal 710 may transmit the schedule information to the presence server 500. .

The presence server 500 manages information about whether buddies are online, how to connect, and the status of subscribers based on SIP (or XCAP). Server that manages logical and physical state information.

In addition, the presence server 500 is coupled to the terminal 710 and the schedule server 720 through a communication network. The presence server 500 receives schedule information from the schedule server 720, and changes the presence information of the subscriber to the terminal of another user who shares the presence information with the subscriber. Can be transmitted.

For example, the presence server 500 may register by changing status information or a screen name using a title of schedule information. The presence server 500 may transmit the presence information including the changed status information or the screen name to a terminal of another user who shares the presence information with the subscriber.

8 is a flowchart illustrating a method of changing the presence information according to an embodiment of the present invention. Hereinafter, a subscriber accesses a schedule server having a schedule function and registers a schedule, and then the schedule information registered in the schedule server is transmitted to the presence server 500. Of course, the schedule information may be transmitted to the presence server 500 through the terminal of the subscriber, but in this specification, it is assumed that the schedule information registered by the subscriber is received through the schedule server 720. Shall be. As described above, the schedule server 720 may be an Outlook server having a schedule function.

In operation 810, the schedule server 720 receives a schedule from a user. The schedule server 720 generates schedule information by using the registered schedule and time information according to the schedule, and transmits the schedule information to the presence server 500. Here, it is obvious that the schedule information may be daily, weekly, monthly or annually.

In addition, as described above, after the subscriber's terminal receives a schedule from the user, the subscriber's terminal may generate schedule information and transmit the schedule information to the presence server 500.

In operation 815, the presence server 500 receives schedule information from the schedule server 720.

In operation 820, the presence server 500 analyzes the received schedule information to determine whether a time corresponding to the schedule information has been reached.

For example, the presence server 500 may compare the schedule and time information included in the schedule information with the current time information and determine whether the time corresponding to the schedule information has been reached. Of course, when the presence information 500 includes a plurality of schedules, it is natural that the schedule server 500 may determine whether the time corresponding to each schedule has been reached by comparing the current time with each schedule. .

If it is determined that the time corresponding to the schedule information has been reached, the presence server 500 changes the subscriber's presence information using the schedule information in step 825.

For example, the presence server 500 may change the status information or the screen name of the subscriber by using the title of the schedule included in the schedule information.

In operation 830, the presence server 500 may transmit the changed presence information to a terminal of another user who shares the presence information with the subscriber.

Before transmitting the changed presence information, the presence server 500 may precede the process of determining whether another user who shares the presence information with the subscriber is connected. Accordingly, the presence server 500 may transmit the changed presence information to other users who are connected.

However, if the time corresponding to the schedule information has not been reached, wait at step 820.

In addition, the presence server 500 may determine whether the time information is not included in the schedule information or whether the time information included in the schedule information is before the current time. If it is determined that it is before the current time or does not include time information, the presence server 500 may immediately change the presence information by using the schedule information and transmit the presence information to a terminal of another user who shares the presence information.
