Abstract

PURPOSE: A multi-point call service method using a caller ID and a system therefor are provided to allow multiple parties to quickly and conveniently share information by performing call according to selection or authentication of users without having to make a reservation for a group call time point. CONSTITUTION: A user inputs an ID to be connected with a management server(S10). A CID(Caller ID) tracking unit of the management server tracks and recognizes the CID of the user by interworking with a communication system(S12). A call group is generated or a member is added(S15). If a group call is desired without generation of an additional call group, call group information corresponding to the tracked CID are fetched from a call group DB and a group select menu is displayed on an origination terminal(S40). When a call group is selected by the caller, calling is made to every member terminal of the selected call group through a multi-channel connecting unit(S45). The multi-channel connecting unit determines whether the call connection is successful(S50). Successfully connected participants, namely, the caller and called members, are informed the connection state(S80), and channel allocation and call processing are performed for simultaneous call through the multi-channel connecting unit to thereby proceed with a group call(S85).

Preferably, the present invention is characterized in that a message is transmitted to the callback service together with the call, and the callback is made from the member terminal to the management server according to the access action of the member side after the end of the group call service.

According to another aspect of the invention, the storage unit for storing the call group information for each user; CID tracking unit for detecting the caller ID (CID) of the user connected to the call; Drawing means for extracting call group information corresponding to the calling party number (CID) from the storage and displaying the same on the user terminal; And a multi-channel connection unit for performing a call to a member terminal of a talk group selected by a user and performing channel assignment and call processing for a group call between a user and members who have responded to the call. Is provided.

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

First, Figure 1 shows a preferred embodiment of a multi-party call service system according to the present invention. Referring to the drawings, the present invention provides a user terminal including a calling party terminal 1 and a called party terminal 2, and a management server 10 interworking with the communication system 5 and providing a multi-party call service to the user terminal. Is implemented.

The communication system 5 here is a conventional communication device on the wired and / or wireless carrier side, including a signal network switch, a subscriber switch and the like. In the communication system 5, although not shown in the drawings, a gateway may be installed to connect different types of communication networks.

As a user terminal, a mobile terminal such as a mobile phone or a PDA can be used for easy menu selection, and a computer terminal based on Voice over Internet Protocol (VoIP) can be used, and ARS (Automatic) is provided on the management server 10 side. If a response system is additionally established, a wired telephone may be used.

In the present invention, one user terminal may be both a calling terminal and a called terminal, but for convenience, the side requesting a group call by first connecting to the management server 10 will be referred to as a calling terminal.

The management server 10 includes a CID tracking unit 11 for recognizing caller ID (CID), a data input / output control unit 12 for inputting and outputting data to and from the call group DB 13, a multi-channel connection unit 14, And an additional service control unit 15 and a billing processing interlocking unit 16.

The CID tracking unit 11 tracks and detects the CID information in association with the communication system 5 to recognize the identification number of the calling terminal 1 connected to the management server 10 and converts the information into a data input / output control unit ( To 12).

The data input / output control unit 12 stores the call group related information input from the calling terminal 1 or the called terminal 2 in the call group DB 13 which is a storage unit, and is transmitted from the CID tracking unit 11. The call group information corresponding to the CID is withdrawn from the call group DB 13 so that the call group menu is displayed on the calling terminal 1 corresponding to the CID information.

In the present invention, the call group DB 13 may have a data structure including a table as shown in FIG. 2, where each field is entered by a creator of a group or a recipient approves joining a group. This is about the information field of members belonging to the registered group.

2 (a) is a member data structure, where Group_Id represents a unique ID of a group assigned by a management server 10 when a user creates a group, and Member_Id is unique to a member of each group in the management server 10. ID (e.g., subscriber's phone number) is given. Active_Flag indicates whether the corresponding member is currently participating in the group call, and Approw_Flag indicates whether or not the user wants to participate in the group call. Member_MIN represents a field corresponding to a terminal number of a member, and may include a plurality of subfields when there are several terminals registered by a member.

2B is a call group data structure, where Group_Owner_MIN is a field indicating a caller number (CID) of a group creator, that is, a terminal number. Group_Id is the same as (a) of FIG. 2, and Simple_Id represents a unique ID configured by, for example, 1 to 2 digits to simply refer to a call group. In addition, Active_Flag is a field indicating whether a corresponding talkgroup is currently in a service state, and Priority indicates a priority value determined by the call frequency, talk time, group size, etc. of the talkgroup. Intro_Message represents the self introduction, group introduction, and group call request input by the group creator. Name_SMS is information transmitted through SMS for group call request and corresponds to text information representing each call group. In addition, Image_Animation represents an animation information field such as a character representing a call group transmitted to a called terminal for a group call request. data is a field for storing group call contents and indicates recorded call information for a user who does not participate in a group call.

In this case, Group_Id is used as a key field for interconnecting call group data and member data, but if necessary, the data structure may be separated into two or more data structures, or other data fields may be used to interconnect data structures. .

In addition, it is preferable to automatically check the service status and information of the call group belonging to the user when the user's management server 10 is connected.

The multichannel connection unit 14 performs channel allocation and call processing in association with the communication system 5. That is, when the user of the calling terminal 1 selects a talk group, each call terminal 2 corresponding to the call group member is called, and each called terminal 2 and the calling terminal corresponding thereto are called. (1) Allocate a channel among them to perform call processing to enable group calls. Here, the channel allocation or call processing technique for the group call can use, for example, conventional methods and other various known methods.

The additional service control unit 15 induces group registration or provides additional services for user convenience, such as transmitting various guide information, recording call contents, and call back service for the multi-party call service of the present invention.

To this end, the additional service control unit 15, it is preferable to include an audio information generating unit for generating a sound message is transmitted to the member terminal when the call to guide the group call service, or receives a voice message from the user Do.

In addition, more preferably, as a guide window that is transmitted to the member terminal side during the call to guide the group call service, generating a guide window including at least one of a text message, animation, a call group identifier or a billing information guide message. The guide window generator may be included in the additional service controller 15.

In addition, the additional service control unit 15 cooperates with the data input / output control unit 12 to activate the call group when the call group information corresponding to the detected CID is active, an activation frequency, a group size, and the like. This function determines the priority according to the information. Accordingly, for example, it is possible to first read information of a group having a high frequency of communication from the call group DB 13 and display it on the calling terminal 1 side.

In addition, the additional service control unit 15 may transmit a message for instructing a callback service to the member who did not participate in the group call, and even after the group call is completed, the member accesses the management server 10 and records the recorded call contents. You can listen to it.

The billing processing linkage unit 16 generates billing information according to service usage while interworking with the billing processing system of the telecommunications provider and automatically performs billing processing based on the billing information. In this case, the billing processing linkage unit 16 may apply a billing form or a rate (Rate) differently for each group or individual, based on the size of the group, the group call time zone or the individual access time.

Next, a process of performing the multi-party call service method according to the present invention through the system configured as described above will be described with reference to FIGS. 3 and 4. 4 shows a screen displayed on the calling terminal 1 side.

First, the user who wants to receive the service is connected to the service system, that is, the management server 10 by inputting an identification number on the calling terminal 1 as shown in ① of FIG. 4 (step S10). In this case, alternatively, a dedicated button provided in the calling terminal 1 or a shortcut key such as ** SEND may be connected in such a manner.

When the user connects to the system, the CID tracking unit 11 of the management server 10 tracks and recognizes the calling party number (CID) in association with the communication system 5 (step S12).

After the user accesses the service, a process of selecting a call group or adding a member as shown in ② of FIG. 4 is performed (step S15). When accessing the first service or registering a call group, the user wants to join as a member. The recipient's identification number is entered (step S20).

The additional service control unit 15 of the management server 10 transmits a message for inducing group member registration to the destination terminal 2 corresponding to the inputted identification number of the called party, including information for guiding group call registration (step S25). ). Accordingly, the voice terminal or sound for guiding the group call may be transmitted to the called terminal 2 side, and a text message for guiding the group call may be transmitted as shown in FIG. 5, and more preferably, as shown in FIG. 6. Guidance information including animations representing groups is displayed.

Here, it is preferable that the sender or the calling group name is transmitted together with the guide information, and information such as a billing type and a billing rate according to service use may be additionally transmitted.

In step S30, when the called party approves the group call and takes an optional action of pressing the 'OK' button to transmit the approval item to the management server 10, the data input / output control unit 12 of the management server 10 is transmitted. Member registration is made in the call group DB 13 (step S35).

On the other hand, when the caller wishes to make a group call without creating an additional call group, the call group information corresponding to the CID information tracked in step S12 is extracted from the call group DB 13 through the data input / output control unit 12, for example. In step S40, the group selection menu is displayed on the calling terminal 1 as shown in ③ of FIG. In this case, the item of the group displayed on the calling terminal 1 may be displayed with the priority of the currently active group, and may additionally indicate the number of activated members (see the number in parentheses). .

When the call group is selected by the caller, the call is performed to all member terminals of the corresponding call group through the multi-channel connection unit 14 (step S45), and the caller terminal receives a message indicating that the call is being performed as shown in ④ of FIG. It can be displayed.

Subsequently, the multi-channel connection unit 14 determines whether a call connection is successful (step S50). Accordingly, when it is recognized that the connection has failed, it is determined whether the communication failure is the cause again (step S55), and when the communication failure or the call is performed, the redial process is performed, in which case, the number of repetitions of the redial can be limited. Step S60).

If the cause of the connection failure is not a communication failure, the multi-channel connection unit 14 checks whether or not a group call rejection event has occurred from the called terminal 2 side (step S65), and if the called party rejects the caller, the caller reports the matter. After notifying the member, the transmission to the member is terminated.

On the other hand, if the call is not connected without the event of rejection, for example, the missed call message as shown in FIG. 7 is transmitted (step S70). At this time, the missed call message further includes information for guiding the callback service, and the called party can later access the management server 10 through the callback service and listen to the group call contents stored in the call group DB 13. It is desirable to. Such a callback service guide message is not necessarily transmitted to a missed call, but may be transmitted to all members during a call so that the user can conveniently reconnect and check the stored contents after the service ends.

On the other hand, as shown in ⑤ of FIG. 4, the participant who has successfully made a call, that is, the caller and the members responding to the call is notified of the connection state (step S80), and the channel allocation for the simultaneous call through the multi-channel connection unit 14 is performed. An over-call process is performed and group call proceeds (step S85).

In addition, as described above, the call group creator can start a group call as well as start a group call with the members of the group to which the group belongs by using the call group DB 13, which also includes all members of the call group. can do. That is, the member_Id stored in the call group DB 13 of the management server 10 may be searched to allow a group call to be initiated to members belonging to the group if a corresponding group exists.

In the above, preferred embodiments of the present invention have been described with reference to the accompanying drawings. Herein, the terms or words used in the present specification and claims should not be interpreted as being limited to the ordinary or dictionary meanings, and the inventors properly define the concept of terms in order to explain their own invention in the best way. It should be interpreted as meaning and concept corresponding to the technical idea of the present invention based on the principle that it can. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

In the multi-party call service according to the present invention, since the call service is performed at any time according to the user's selection or approval without having to reserve a group call point in advance, there is an effect that the information can be quickly and conveniently shared between the multi-party.

In particular, the present invention has an advantage that the cumbersome unique number assignment or authentication process for the group call can be omitted because the call group is automatically activated by recognizing the caller's CID to initiate the group call.

In addition, the present invention provides a service for transmitting a text message, a voice message, a sound, an animation, etc. to the called party to induce joining a talkgroup, thereby creating and expanding a talkgroup.
