1 is a diagram illustrating a mobile communication system 100 according to an embodiment of the present invention. As shown in FIG. 1, the mobile communication system 100 may include a terminal and a mobile communication network.

The terminal may include personal digital assistants (PDAs) having a wireless communication function, computers, and the like, as well as devices used for wireless communication. The terminal may be fixed or mobile, and may be referred to as terms such as a mobile station (MS), a user equipment (UE), a subscriber station (SS), a wireless device, etc., but is not limited thereto.

Such a terminal may be classified into an originating terminal for sending a call and a terminating terminal for receiving a call according to a role in the mobile communication system. The terminal performs location registration for the local area. The location area refers to a geographical limit in which a terminal registers a location. The location area may vary depending on the mobile communication network, but the minimum unit is coverage. The location area may be a range of each base station, may be a combination of a range of several adjacent base stations, and may be broadly all base station ranges managed by one mobile exchange. When a call connection is attempted to the called terminal, a paging for searching for the called terminal is broadcast from all base stations in the location area.

The called terminal may include a call rejection device according to an embodiment of the present invention. That is, the apparatus for rejecting a call may mean a part of a called terminal or may mean a called terminal itself. The do not reject device may provide a user interface for rejecting an incoming call received at the called terminal and transmitting guide content related to the rejection. A more detailed description of the rejection apparatus will be described later with reference to FIG. 2.

The mobile communication network may include a circuit service network 10 and / or a packet service network 20. The circuit-switching network 10 refers to a network using a circuit-switching scheme. In the circuit-switching network 10, when a communication line for a call is established between users, the line is dedicated to only those involved in the call during the call. In contrast, the packet-switching network 20 refers to a network using a packet-switching method, which divides data into packet units and transmits the packet to a destination address included in the packet.

The circuit switched network 10 described above includes a base station 110, a radio network controller (RNC) 120, a mobile switching center (MSC) 130, and a home location register (HLR) 150. , And a gateway mobile service switching center (GMSC) 140.

The base station 110 may transmit / receive various signals and data with a terminal in a cell managed by the base station 110, and may perform a role such as wireless channel management in the base station 110. The base station 110 may also be referred to as terms such as node-B, base transceiver system (BTS), and access point.

The RNC 120 may control the base station 110 and manage radio resources. More specifically, the RNC 120 may instruct the base station 110 to allocate a communication channel to the terminal and control the transmission output of the base station 110. In addition, the radio network controller may support handoff for a terminal moving between base stations.

The MSC 130 may also be referred to as a 'voice exchanger', and may be connected to one or more RNCs 120 to relay communication between the terminal and another terminal. In addition, the MSC 130 may serve as a service switching point (SSP) for providing an intelligent network service. For example, the subscriber's incoming and outgoing call processing, location registration procedure, and handoff procedure processing. In addition, interworking with external networks can be performed. In addition, the MSC 130 may perform a function of a visitor location register (VLR).

The GMSC 140 may serve as a gateway that enables communication between a mobile communication network and an external network (eg, PSTN, ISDM). That is, the call and traffic coming into the mobile communication network from the external network, and the call and traffic output from the mobile communication network to the external network may be forwarded by the GMSC (140).

The HLR 150 stores and manages the location information of the subscriber (for example, the address of the VLR where the destination terminal is currently located, the MSC 130 address, status information, etc.) and provides it to the system requesting this information. do. In addition, the HLR 150 stores information necessary for a subscriber to receive a communication service, such as subscriber additional service information, in a database, and if necessary, transfers the information to the MSC 130 or the Visitors Location Register (VLR). Helps you get additional services.

Meanwhile, the packet switched network 20 may include a packet switching support node (SGSN: Serving GPRS Support Node, 160), a packet switching gateway (GGSN: Gateway GPRS Support Node, 170), and a packet data switching node (PDSN: 180). And a packet data gateway node 190 (PDGN). Of these, SGSN 160 and GGSN 170 are equipments required to provide packet data services in an asynchronous network (eg, W-CDMA, UMTS, GPRS, etc.). The PDSN 180 and the PDGN 190 are equipments for providing a high speed data service in a synchronous network (eg, a 3GPP2 standard mobile communication network based on CDMA2000).

SGSN 160 supports the mobility management of the terminal for the GPRS (General Packet Radio Service), the call processing procedure, and session management, authentication and billing functions for processing the transmission and reception of packet data. It also has a routing processing function of packet data.

The GGSN 170 is a serving node of an IP (Internet Protocol) -based packet network that provides a high-speed packet data service for GPRS data service. The GGSN 170 manages a session for packet data service and performs routing of packet data. It provides an interface for connecting packet switched network and internet network.

PDSN 180 may perform a function similar to SGSN 160. For example, the terminal is responsible for authentication and authorization required for receiving packet services, packet routing, handover for ensuring mobility, QoS, accounting, and the like. PDSN directly handles data without going through MSC, assigns IP to terminals, or manages overall wireless Internet connection.

The PDGN 190 may perform a function similar to the GGSN 170.

If the user input unit 210 and the output unit 220 are implemented in a hardware-separated form, the user may select a desired call rejection method using a button or a key provided in the user input unit 210. If the user input unit 210 and the output unit 220 are implemented in a hardware-integrated form such as a touch screen, the user can directly select a desired call rejection method from the listed items.

As shown in FIG. 3, the call rejection apparatus 200 according to an embodiment of the present invention is a call rejection method, and a method of transmitting only a voice message (hereinafter, referred to as a 'un rejection voice message') for the call rejection, and the call forwarding. How to send a text message on the reason for refusal after sending a rejection voice message, how to allow a caller to record a voice message after sending the refusal voice message, and how to send the contents of the rejection. It can be seen that.

As a call rejection method, if a method of transmitting only a call rejection voice message is set, when the call is received, as illustrated in FIG. 4, the caller's telephone number of the calling terminal 21 and the rejection icon for executing call rejection ( A user interface 400 can be provided that includes 410. When the rejection icon 410 is selected in the user interface 400 of FIG. 4, the rejection voice message (for example, a voice message of 'I cannot answer a call') is displayed as guide information for the rejection. It is transmitted to the calling terminal 21. At this time, the call rejection voice message may be a sound source that is basically stored in the rejection apparatus 200, or a sound source recorded directly by the user may be used.

As a method of rejection, if a method of transmitting a text message for the cause of rejection after the rejection voice message is set, the user interface 400 as illustrated in FIG. Can be. When the rejection icon 410 is selected in the user interface 400 illustrated in FIG. 4, the rejection voice message may be transmitted to the calling terminal 21 as guide information for the rejection. Thereafter, as shown in FIG. 5, a user interface 500 may be provided for transmitting a text message for the cause of the rejection. The user interface 500 for sending a text message includes an item in which the user can directly write a text message on the reason for rejection, such as' newly created ', and' in a meeting ',' during driving ',' during class', ' May include items that are stored by default with respect to the refusal reason. When a predetermined item is selected in the user interface 500 illustrated in FIG. 5, a text message related to the selected item may be transmitted to the calling terminal 21. Specifically, when an item 510 of 'in a meeting' is selected in the user interface illustrated in FIG. 5, for example, a text message of 'now in a meeting and cannot receive a call' is sent to the calling terminal 21. Can be sent.

As a call rejection method, if a method for allowing a caller to record a voice message after a call forwarding voice message is set, the user interface 400 as illustrated in FIG. 4 may be provided at the time of call forwarding. . When the rejection icon 410 is selected in the user interface 40 illustrated in FIG. 4, the rejection voice message may be transmitted to the calling terminal 21 as guide information for the rejection. Thereafter, a guide comment for guiding voice message recording may be provided to the calling terminal 21.

If the call rejection method is set to transmit the guide content for the rejection, the user interface including the rejection icon 610 and the menu icon 620 as illustrated in FIG. 600 may be provided. When the rejection icon 610 is selected in the user interface 600 of FIG. 6, the rejection voice message may be transmitted to the calling terminal 21 as guide information for the rejection. If the menu icon 620 is selected, as illustrated in FIG. 7, a user interface 700 including summary information about pre-stored guide contents may be provided.

Here, examples of the guide content may include a still image, a video, and an emoticon. These guide contents may be photographed through a camera provided in the receiving terminal 20, or may be downloaded from a content storage server 30 connected to a mobile communication network, and may be received from an external device such as another terminal or a personal computer. It may be, but is not limited thereto.

Summary information of the guide content is information that allows the user to grasp the content of the guide content at a glance. The summary information on the guide content may be initially set by the content provider providing the corresponding guide content, or may be modified by a user who receives and uses the guide content from the content provider. If the guide content is generated by the called terminal 20 itself, the user can directly set the summary information on the generated guide content.

Such guide content may be classified into categories according to contents and stored in the storage unit 240. For example, the contents may be classified and stored according to categories such as work, driving, and movies according to contents of the guide content. In this case, the guide contents may be automatically classified and stored according to categories according to the summary information, or when the user directly designates a specific category, the guide contents may be stored in a designated category regardless of the summary information of the guide contents.

When only one guide content exists for each category, as illustrated in FIG. 7, a user interface 700 in which summary information items of pre-stored guide contents are provided is provided as it is. However, when a plurality of guide contents exist in one category, FIG. 8. As such, the name of the category to which the plurality of guide contents belong may be provided through the user interface 800. In this case, an icon 840 indicating that a plurality of guide contents exist in the corresponding category may be displayed beside the name of the category. When a category including a plurality of guide contents is selected, a user interface 850 including summary information of guide contents belonging to the selected category may be provided.

On the other hand, if a predetermined summary information item is selected in the user interface 700 or 800 illustrated in FIG. 7 or FIG. 8, and then the transmission icon 710 or 810 is selected, the call forward is rejected together with the guide content corresponding to the selected summary information item. The voice message may be sent to the calling terminal 21. For example, if the transmission icon 810 is selected after the summary information 850 of 'in a meeting !!' is selected in the user interface 800 of FIG. 8, the guide content as illustrated in FIG. 9 is a rejection voice. The message may be transmitted to the calling terminal 21 together with the message.

As described above, the transmission of the rejection voice message and the guide content may be performed when the separate transmission icons 710 and 810 are selected after the selection of the summary information is selected, or may be performed simultaneously with the selection of the summary information. . Specifically, unlike the user interfaces 700 and 800 illustrated in FIG. 7 or 8, as illustrated in FIG. 10, the user interface 900 including summary information about the guide contents does not include a reject icon. If not, the user selects the summary information 910 of 'driving' and at the same time, the selected guide content and the rejection voice message may be transmitted to the calling terminal 21.

11 is a flowchart illustrating a call rejection method according to an embodiment of the present invention. Prior to describing the call rejection method according to an embodiment of the present invention, it is assumed that the call rejection method in the called terminal 20 is a method of transmitting the guide content after the call rejection voice message is set.

The call generated from the calling terminal 21 may be received by the called terminal 20 via the circuit switched network 10 (S11). Here, the call reception process to the called terminal 20 will be described in more detail. First, when a call occurs in the calling terminal 21, the base station 111 of the calling party recognizes a radio signal from the calling terminal 21, converts it into a digital signal, and transmits the signal to the RNC 121 of the calling party. The RNC 121 of the calling party transmits call request information including the telephone number of the called terminal 20 to the MSC 131 of the calling party. The MSC 131 of the calling party requests the VLR in the MSC 131 for additional information (eg, whether to stop calling, authentication information, etc.) about the calling terminal 21, and the calling terminal 21 as a response to the request. Additional information about is provided from the VLR. After the authentication of the calling terminal 21 is performed based on the additional information provided from the VLR, the MSC 131 of the calling party requests the RNC 121 of the calling party to allocate a radio channel for a call. Then, the RNC 121 of the calling party determines the radio channel to be used for the call, and requests the base station 111 of the calling party to set the radio channel. Then, the base station 111 of the calling party sets the radio channel for the call to the calling terminal 21. Thereafter, the MSC 131 of the calling party requests the information of the called terminal 20 from the HLR 150 in which the called terminal 20 is registered. The HLR 150 transmits the related information of the called terminal 20 including the information of the MSC 130 where the called terminal 20 is located to the MSC 131 of the calling party. The MSC 131 of the calling party notifies the MSC 130 of the called party the telephone number of the called terminal 20, and requests connection of the call. The MSC 130 of the called party requests the VLR in the MSC 130 for location information about the called terminal 20 and information related to the called party. Then, in response to the request, the VLR in the MSC 130 transmits information related to the called terminal 20 to the called MSC 130. When the MSC 130 of the called side uses the location information of the called terminal 20, paging for setting up a call to the called terminal 20 to the RNC 120 of the called side 20 when an incoming signal occurs in the mobile terminal. Call the terminal through the RNC of the zone where the terminal is located. The RNC 120 transmits a paging message for call connection with the called terminal 20 to the base station 110 at the called side. Then, the base station 110 of the called party calls the called terminal 20 through the wireless channel.

When the call is received by the called terminal 20 through the above-described process (S11), the called terminal 20 according to the preset call rejection method, as shown in FIG. 6, the rejection icon 610 and the menu icon 620 A user interface 600 including) may be provided (S12).

When the user interface 600 of FIG. 6 is provided, it may be determined which icon is selected from the reject icon 610 and the menu icon 620 (S13). The determination process may be performed by the controller 230 described above.

If the reject icon 610 is selected in the user interface 600 of FIG. 6, a call rejection voice message may be transmitted (S14). Specifically, when the reject icon is selected, the called terminal 20 transmits a response signal to the paging, and then opens a traffic channel. Then, the rejection voice message may be transmitted to the base station 110 through the corresponding traffic channel. The transmitted rejection voice message may be transmitted to the calling terminal 21 through the circuit switched network 10.

If the menu icon 620 is selected in the user interface 600 of FIG. 6, as illustrated in FIG. 7 or 8, user interfaces 700 and 800 including summary information about pre-stored guide contents are illustrated. May be provided (S15).

After the predetermined summary information item is selected in the user interface 700 or 800 of FIG. 7 or FIG. 8 (S16), and when the transmission icons 710 and 810 are selected (S17), the guide content corresponding to the selected summary information item and The unsubscribe voice message may be transmitted (S18). Specifically, when the summary information item is selected, the called terminal 20 opens a traffic channel after transmitting a response signal to the paging. Then, the call rejection voice message and the selected guide content may be transmitted to the base station 110 through the corresponding traffic channel. The transmitted rejection voice message may be transmitted to the calling terminal 21 through the circuit switched network 10. The transmitted guide content may be transmitted to the calling terminal 21 through the packet switching network 20.

On the other hand, unlike the user interface (700, 800) of Figure 7 or 8, as shown in Figure 10, if the user interface 900 including a summary item for the pre-stored guide content does not include a transmission icon, the guide content After the step S16 of selecting the summary information item, the step S17 of selecting the transmission icon may be omitted.
