Description

Method and terminal for displaying of calling identification using presence information}

The present invention relates to a mobile communication system, and more particularly, to a method and a terminal capable of displaying caller information using IMS-based presence information.

Caller ID service, commonly known as a Caller Identification Display (CID) service, displays the caller's phone number on the display when receiving a call to a subscriber's terminal, so that the caller can be identified before the call is made. It is a mobile communication additional service that provides a function.

 Existing caller ID (CID) service provides the caller's information to the terminal or the dedicated display device of the receiver before the call is initiated, thereby preventing infringement of communication privacy such as anonymous call violence and obscene calls.

The caller ID display service allows the caller's terminal number to be displayed on the LCD screen before or during a call to selectively make calls, to protect against call violence such as violence and mischief calls, and to provide information about the caller's information on a missed call. The time was displayed so that you could check all of your missed receptions. In addition, an automatic call can be made to the calling number displayed on the screen, and a new call can be checked even during a call.

Currently, the caller information display service includes a short phrase designated by a user or a URL including multimedia information designated by the user in a call reception notification message.

However, when the URL is included in the incoming call notification message and transmitted, the caller information is displayed by downloading the contents of the URL by connecting the data call after receiving the URL. For this reason, it takes a considerable time to display the caller information, there is a problem that can not display the caller information because the content corresponding to the URL is not downloaded when the network traffic situation is not good.

The present invention is to provide a caller information display method and a terminal capable of displaying caller information by using the presence (presence) information.

In addition, the present invention is to provide a caller information display method and a terminal that can display the caller information immediately after the incoming call to reduce the time delay caused by the caller information display.

In addition, the present invention is to provide a method and a terminal for displaying a caller information that can prevent the caller information is not displayed due to network traffic.

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

According to an embodiment of the present invention, a method of displaying presence information as a caller information in a called terminal, the method comprising: receiving and storing the presence information of the calling terminal; Receiving a communication call connection message corresponding to the calling terminal; And extracting the presence information of the calling terminal in response to the communication call connection message and outputting the presenting information as caller information.

According to another aspect of the present invention, a terminal capable of displaying presence information as caller information is provided.

According to an embodiment of the present invention, a called terminal for displaying the presence information as caller information, the called terminal comprising: a storage unit for storing the presence information of the calling terminal; A receiving unit receiving a communication call connection message from the calling terminal; A controller which determines whether presence information mapped to the calling terminal is present according to the communication call connection message, and extracts and outputs presence information mapped to the calling terminal if present; And a display unit for outputting the presence information to the outside under the control of the controller.

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

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., active, offline, 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 originating terminal 120 and transmits the soft-state and hard-state presence information to terminals registered in the buddy list corresponding to the originating terminal 120.

The present invention transmits the presence information of the calling terminal to a plurality of terminals (i.e., called terminals) that share the presence information with the calling terminal, and then the presence information corresponding to the origination signal of the calling terminal. It can be displayed as caller information. Accordingly, for the purpose of convenience of understanding and explanation, the subject information is changed, and the subject to which the presence information is transmitted is collectively referred to as the calling terminal, and received and stored the presence information of the calling terminal. According to the present invention, a terminal displaying the presence information as caller information will be described collectively as a called terminal.

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

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

First, the originating terminal 120 transmits a "PUBLISH" message to the presence server through the IMS core, and the "PUBLISH" message includes the state information of the originating 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 calling terminal 120 to the called terminal 110 through the IMS core.

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

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

First, the calling terminal 120 generates hard-state information (for example, its own group list, user permission information about presence information, etc.) in PIDF format through the XCAP interface, and sends it to the XML Data Manipulation Server (XDMS). Register.

Thereafter, the XDMS transmits a "NOTIFY" message including hard-state information of the calling terminal 120 to the presence server, and the presence server delivers a "NOTIFY" message to the called 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 required for driving the 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.).

In addition, although not illustrated in FIG. 4, the presence information may include nickname information set by the user. In addition, the presence information according to the present invention may be set differently for each group registered in the buddy list.

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

Referring to FIG. 5, the calling terminal 120 according to the present invention includes a transceiver 510, an input unit 515, an information setting unit 520, a storage unit 525, a display unit 530, and a controller 535. It is configured to include.

The transceiver 510 is connected to a server (not shown) or another terminal that provides arbitrary information through a communication network to transmit and receive data.

For example, the transceiver 510 may transmit the presence information set by the information setting unit 520 to the terminal of the user registered in the buddy list of the IMS service through the IMS network. Here, the transceiver 510 may transmit the presence information to a presence server (not shown) under the control of the information setting unit 520, or may transmit the presence information to each registered terminal via the presence server.

For example, when a call key is pressed by a user's key operation, the calling terminal 120 may request an outgoing signal to an exchange (not shown) through the base station. In response, the exchange may transmit a communication call connection message to the called terminal in response to the call request. The called terminal may display the caller information using the presence information when the communication call connection message is received.

The input unit 515 is a means for receiving various control commands for controlling the operation of the calling terminal 120 from the user. For example, the input unit 515 may be implemented as a plurality of key buttons (for example, numeric / character keys, * or # symbols, and one or more function keys (for example, menu keys, call keys, confirmation keys, etc.). It may be implemented in the form of a touch screen or the like.

The information setting unit 520 receives information to be displayed on behalf of the caller in response to the originating signal of the calling terminal 120 from the user through the input unit 515 and sets it as the presence information. For example, the presence information in this specification may be nickname information registered on the IMS service.

In addition, the information setting unit 520 may set the presence information for each group by receiving information differently for each group registered in the buddy list of the IMS service.

In the present specification, it is assumed that the information setting unit 520 receives the information to be displayed corresponding to the originating signal and sets the information as the presence information. Naturally, for example, a nickname can be set differently and transmitted.

The information setting unit 520 is configured to share the presence information through the transmission / reception unit 510 with each other (that is, a terminal of each user registered in the buddy list in the IMS service (eg, each called terminal). Presence information can be transmitted with)).

As another example, the information setting unit 520 may be selected (or set) as an image for displaying the caller from the user and may be set as the presence information.

In the present specification, the presence information may be used by receiving (or selecting) all of the information for identifying the caller in the called terminal 110 in response to an outgoing call of the calling terminal 120.

The storage unit 525 stores various information files received through an algorithm, software, and a transceiver unit 510 for operating the calling terminal 120 according to the present invention.

The display 530 displays data corresponding to a command input by the user through the input unit 515 and data received through the transceiver 510. For example, the display unit 530 may be a liquid crystal display (LCD).

The control unit 535 is the internal function of the calling terminal 120 according to the present invention (for example, the transceiver 510, the input unit 515, the information setting unit 520, the storage unit 525, the display unit 530, etc.).

6 is a block diagram showing an internal functional configuration of a called terminal according to an embodiment of the present invention. Hereinafter, a description overlapping with the calling terminal 120 described with reference to FIG. 5 will be omitted.

As shown in FIG. 6, the destination terminal 110 includes a transceiver 610, an input unit 615, a presence information management unit 620, a storage unit 625, a display unit 630, and a control unit 635. It is configured to include. Hereinafter, descriptions of functions of the transceiver 610, the input unit 615, the storage unit 625, and the display unit 630 similar to those described with reference to FIG. 5 will be omitted.

The presence information manager 620 receives and stores the presence information of the calling terminal 120 through the transceiver 610.

For example, the presence information manager 620 may obtain an identification number (for example, a phone number, a MIN number, etc.) of the calling terminal 120, and may map and store the identification number and the presence information.

When the communication call connection message corresponding to the calling terminal 120 is received through the transceiver 610, the controller 635 determines whether there is presence information mapped to the calling terminal 120. If the presence information exists, the controller 635 extracts the presence information of the calling terminal 120 and outputs the same through the display 630 as caller information. However, if the presence information mapped to the calling terminal 120 does not exist, caller information is displayed by the same method as in the related art.

For example, the called terminal 110 may use some information from the presence information as information for calling party display. That is, the called terminal 110 may display the caller information by using the extracted state information or call information from the presence information.

7 is a flowchart illustrating a method in which a called terminal displays presence information as caller information according to an embodiment of the present invention. Each step described below is performed by each internal function configuration of the destination terminal 110, but will be collectively described as a destination terminal for the convenience of understanding and explanation.

In step 710, the calling terminal 120 receives the information from the user and sets the presence information. In addition, the calling terminal 120 transmits the set presence information to terminals corresponding to each user registered in the buddy list.

As described above, the calling terminal 120 may receive the information for each group registered in the buddy list, set the presence information, and then transmit the presence information set to each terminal corresponding to the user included in each group. . Of course, the calling terminal 120 may receive the information for each individual and set the presence information.

In step 715, the called terminal 110 receives and stores the presence information of the calling terminal.

In step 715, the called terminal 110 is requested to connect to the communication call from the calling terminal 120.

In operation 720, the called terminal 110 determines whether presence information corresponding to the calling terminal 120 exists.

For example, the called terminal 110 may determine whether the presence information mapped to the identification information of the calling terminal 120 is stored using the identification information of the calling terminal 120.

If present, the called terminal 110 extracts the presence information corresponding to the calling terminal 120 in step 725.

In operation 730, the called terminal 110 outputs the extracted presence information through the display unit 630 as caller information.

If not present, however, in step 735, the called terminal 110 outputs caller information through the display unit 630 according to a conventional caller display method. If the calling terminal 120 is not subscribed to the caller ID service, the called terminal 110 outputs the identification number of the calling terminal 120 through the display unit 630.
