System and Method for Intermediation of Simultaneous Call Using Auto Response Service in Wireless Communication System

The present invention relates to a simultaneous call system in which a large number of participants can call simultaneously, and more particularly, to a simultaneous call intermediation system using an auto answering service that enables simultaneous call to all targets who want to call simultaneously. And to a method.

Simultaneous calls are phone calls made by three or more participants at the same time, and are primarily used for conference calls. Conventionally, in order to make a simultaneous call, a specific caller has to repeat the process of attempting to call the next person after maintaining a waiting state when a call path is formed by attempting a call to the person to be called.

However, this method has to try to call as many as the number of counterparts wishing to make a simultaneous call, and thus there is a problem in that it takes a lot of time to connect to the call. There is also the inconvenience that all participants must be on hold until the last participant answers the call.

In order to solve the problem of the simultaneous call, a method of requesting a connection request to all the targets who want to make a simultaneous call with only one call attempt has been studied. Therefore, the method of handling the simultaneous call request has to be further refined.

The present invention has been made to solve the above-described problems, it is possible to request a simultaneous call to a plurality of group members with only one call attempt, and to guide the simultaneous call method and progress by using an automatic answering service when the simultaneous call is requested. There is a technical problem to provide a simultaneous call intermediation system and method using an automatic answering service in a wireless communication system.

Another technical problem of the present invention is to wirelessly complete an unconnected call according to a disconnected reason when connected to a call according to a simultaneous call request, and to process an event according to a tone signal input by a user during a concurrent call. The present invention provides a simultaneous call intermediation system and method using an auto answer service in a communication system.

In addition, the present invention is connected to a plurality of wireless terminals and wired terminals through a communication network, to register the group consisting of at least three users to the wireless terminal user, and to the group according to the request of the caller using the wireless terminal A simultaneous call brokerage method for simultaneously attempting a call to an included group member, comprising: a simultaneous call connection process for receiving a simultaneous call request call from the originator; A group identification process for transmitting a announcement to the caller to select a group according to the caller's attempted simultaneous call and confirming whether the group selected for the simultaneous call is registered by the caller and sending a confirmation result to the announcement; A group call attempting process for simultaneously attempting a call to all group members in the group and transmitting a call attempt process and a connection result to the caller as a guide when the group selected by the caller exists; A busy event processing step of processing the user's request by transmitting a result of the simultaneous call connection as a guidement to the caller and interpreting a signal input by the user after the simultaneous call is started according to the group call attempt; And an unconnected call processing process for releasing a call that does not respond after attempting a call to the group members at the same time in the group call attempt process.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, a group means a set of three or more wireless terminal or wired terminal users that can simultaneously participate in a call, and each user included in the group is referred to as a group member.

1 is an exemplary diagram of a communication network to which a simultaneous call brokerage system according to the present invention is applied.

As shown, the simultaneous call intermediation system 30 of the present invention is connected to a plurality of wireless terminals (10-1 ~ 10-n) through a wireless network operator 20, the public switched telephone network (PSTN, 50) It is connected with a plurality of wired terminals 40 through. The base station controller BSC 202 of the wireless network operator 20 enables the wireless terminal to access the wireless network operator 20 through a base station (not shown) and manages the base station. In addition, the exchange (MSC) 40 is connected to the base station controller 202 to perform call setup and release functions of the wireless terminals 10-1 to 10-n, and to perform various functions related to call processing and additional services. It also works with other networks. The home location register (HLR) 206 is a database that stores information, location information, additional service information, etc. of the subscribers of the wireless terminals 10-1 to 10-n, and includes a switch 204 and a visitor location register (not shown). ) To perform functions related to call processing and supplementary services and to control services.

Simultaneous call intermediary system 30, as the user of the wireless terminal (10-1 ~ 10-n) is trying to simultaneously call at least two or more of the wireless terminal (10-1 ~ 10-n) or wired terminal 40, Checks the group of simultaneous calls registered by the user (caller) who requested the simultaneous call, and simultaneously attempts to call the selected group members. When the called party responds to such a call attempt, the simultaneous call intermediation system 30 notifies the caller that the group member has responded to the call attempt, while notifying the called party that a simultaneous call is required, so that the caller's You can check the status of the response and ensure that the called party is not embarrassed by a sudden simultaneous call request. Announcement can be generated and sent as appropriate for every situation that can occur during the simultaneous call as well as the simultaneous call connection attempt process.

In addition, when a call is formed between a plurality of users and a simultaneous call is in progress, when a DTMF (Dual Tone Multi Frequency) pulse or a disconnect request signal is input by the user, simultaneous calls are released and group members are connected according to the corresponding key. Functions such as release, private secret call, etc. can be performed. The simultaneous call relay system 30 may be operated by the wireless network operator 20 or may be operated by an independent operator of the wireless network operator. FIG. 2 is a detailed configuration diagram of the simultaneous call brokerage system shown in FIG. 1. .

As shown, the simultaneous call intermediation system 30 is a group management means 302, announcement processing means 304, call attempt means 306, busy event processing means 308, disconnected call processing means ( 310, a charging means 312 and a database 320. Here, the database 320 includes a group DB 322, the announcement DB 324 and the billing DB 326, each of which may be configured as an independent table or a table. .

The group managing means 302 stores and manages information of a call group composed of at least three or more group members who wish to use the simultaneous call service, and information of each group member constituting the group in the group DB 322. The group information may be, for example, group characteristics, group names, number of members, and the like, and information of each group member may be a phone number, name, age, gender, etc. of the group member.

The announcement processing means 304 requests a simultaneous call when a user who wants a group call connects to the simultaneous call intermediation system 30, when the called party answers a call, or when an event such as a tone input during a call occurs. Or, guides to guide the group members how to use the simultaneous call, progress, etc. are extracted from the guidement DB 324 according to each situation and sent to the user.

For example, if the user of the wireless terminal wants to make a simultaneous call with a desired group, the announcement processing means 304 of the simultaneous call relay system 30 is, for example, a simultaneous call service. Press 1 for concurrent calls, 2 for group management and 3 for help. Press the asterisk to move to the upper menu during the use, and press the well sperm to go to the first time, so that even if you are the first time to use the simultaneous call, you can request the simultaneous call without difficulty. In addition, if the called party responds to the caller's request for simultaneous call, for example, the call is requested by ***. Please wait. Send a comment like this to inform the called party that the current call is a simultaneous call.

As the call attempting means 306 selects a group to which the caller wants to make a simultaneous call, the group attempts to simultaneously call all group members of the group with reference to the group DB 322. In this case, the group member may be a user of the wireless terminals 10-1 to 10-n or the wired terminal 40, and, in the case of the users of the wireless terminals 10-1 to 10-n, through the wireless network operator 20, In the case of the user of the wired terminal 40, a call is attempted through the PSTN 50.

During a call, the event processing unit 308 may disconnect a call, disconnect a group member, or disconnect a private call according to a dual tone multi frequency (DTMF) pulse inputted from a call participant during a call, a disconnect request signal, and the like. After the function is performed, the unconnected call processing means 310 attempts a call to all group members of the corresponding group according to the caller's request, and then requests the unanswered call to release the connection to the base station. The charging means 312 is to calculate the charge according to the time of the simultaneous call and to store the calculation result in the charging DB 326. The charging means 312 is used by the wireless network operator 20. It is a good idea to share and use your own billing server.

3 is a flowchart illustrating a simultaneous call mediation method according to the present invention.

Simultaneous call intermediation method according to the present invention is a simultaneous call connection process (P10), the caller attempts a simultaneous call request call, a group checking process (P20) to check whether the group selected by the caller according to the caller's attempt to call simultaneously registered, Group call attempt process (P30), which attempts to simultaneously call all group members in the group if the group selected by the caller exists, and dual tone multi frequency (DTMF) signal input by the user after the simultaneous call is started according to the group call attempt Or an unconnected call processing process (P50) for releasing an unanswered call after attempting a call to a group member at the same time as a busy event processing process (P40) for interpreting a disconnect request signal and processing a user request. .

Detailed description of each process (P10 ~ P50) will be described later with reference to FIGS.

4 is a flowchart illustrating a simultaneous call connection process, that is, a caller attempting a call requesting a simultaneous call in the simultaneous call intermediation method according to the present invention.

As the caller attempts to make a call using the wireless terminal (S101), the wireless network operator 20 checks whether the corresponding call is a general call or a call requiring simultaneous calling (S102). Here, the general call and the simultaneous call can be distinguished by the simultaneous call identifier, and the simultaneous call identifier can be any one of a specific number, a specific symbol, and a combination of specific numbers and symbols. It is set in advance.

As a result of confirming whether the wireless network provider 20 is a general call or a simultaneous call request call, when the general call is performed, the general call processing process is performed (S103), while in the case of a simultaneous call request call, the simultaneous call is performed by the simultaneous call intermediation system 30. The call request fact is transmitted (S104). Accordingly, the group management means 302 of the simultaneous call intermediation system 30, after referring to the group DB 322 to verify that the caller who requested the simultaneous call is a suitable user (S105), the caller and the simultaneous call identifier Check whether the group number desired for simultaneous call is entered together (S106). That is, in step S101 where the caller attempts to make a call, it is checked whether the group number desired for the simultaneous call is input together with the simultaneous call identification symbol.

If the group number is not input as a result of the check, the guidement processing means 304 of the simultaneous call intermediation system 30 guides the wireless terminal user how to use the simultaneous call with reference to the guidement DB 324. If you want to use the simultaneous call (S108) is switched to the simultaneous call service mode (S109). Here, the announcement is for example a simultaneous call service. Press 1 for concurrent calls, 2 for group lookup and editing, and 3 for help. You may be able to use the instructions such as asterisk to move to the upper menu during the use and press well sperm to go to the first time.

If a group number is input in step S106, the process proceeds to a group checking process (P20) of checking whether a corresponding group exists.

FIG. 5 is a flowchart illustrating a group checking process in the simultaneous call brokering method according to the present invention. After the caller attempts the simultaneous call in FIG. 4, the caller is allowed to select a group for the simultaneous call and whether the selected group exists. A diagram illustrating the checking process in detail.

When a caller requests a simultaneous call by simultaneously entering a simultaneous call identifier and a group number, and after the simultaneous call intermediation system 30 switches to the simultaneous call service mode, the simultaneous call intermediary system 30 attempts to simultaneously call the caller. It is requested to select a group to be made (S201). At this time, it is preferable that the guidement processing means 304 guides the group details registered by the caller with reference to the guidement DB 324. For example, select the desired call group. The friend group is 1, the company group is 2, and the reunion group is 3. If you want to hear it again, you can send a comment like 0, press the asterisk to go to the upper menu during use, and press the well sperm to go to the first time.

Accordingly, when the caller inputs the desired group number (S202), the simultaneous call intermediation system 30 checks whether a group corresponding to the input group number exists (S203), and if the registered group does not exist again, The user selects a group (S201), and if there is a registered group, confirms whether the group checks the corresponding group information or attempts to make a simultaneous call (S204). Thereafter, if the caller wants to check the group information, the caller sends a group information announcement such as a group member list to the caller wireless terminal (S205), and proceeds to step S201 to select a simultaneous call group (S206). Here, the announcement is, for example, the group members of a friend group are: No. 1 ***, no. 2 000, no. 3 &&&. If you want to hear it again, it can be 0, press the asterisk to go to the upper menu during use, or press the well sperm to go first.

On the other hand, if a caller wants to make a simultaneous call with the group member, for example, a call is sent to the first friend group, informing all group members of the group corresponding to the group number entered by the user to attempt the simultaneous call. Send the announcement (S207)

6 is a flowchart illustrating a call attempt process for each group in the simultaneous call mediation method according to the present invention.

After the caller selects a group to be called simultaneously and guides the call to the corresponding group (S207), the call attempt means 306 of the simultaneous call intermediation system 30 is assigned to the group member stored in the group DB 322. With reference to the telephone number and attempts to call all the group members of the group at the same time (S301). At this time, while attempting a call to the group member, the caller sends a notice to the caller's wireless terminal indicating that the call is being attempted (for example, the group member is being called. Please wait a moment) (S302).

After attempting a call to a plurality of group members at the same time, the terminal continuously checks whether a normal incoming response is received from the called party (S303), and if it is not normal, proceeds to an unconnected call processing process (P50). P50) will be described later with reference to FIG. 8.

On the other hand, when a normal incoming response is received from the called party, the caller is notified that the corresponding group member has responded (for example, *** has been connected 1 time) (S304), and the called party participates in the simultaneous call. Guide (for example, XXX has requested a simultaneous call) (S305). As a result, after at least one called party answers, a call path is formed between the caller and the called party, and then a call is possible between users connected to the call path while listening to the announcement about the simultaneous call progress. At this time, while waiting for all the group members to respond, the message indicating the response status of the group members may be heard in the background.

After that, verify that all group members are connected, and if all group members are connected, instruct caller and callee how to connect and how to use the simultaneous call (for example, all three group members are connected. For individual reconnections, press 1 and the group member number, and for individual disconnection during a call, press the 2nd group member number) (S307, S308), if there is an unconnected group member, call the caller and the called party. Before we show you the results of the connection and how to use the simultaneous call, you will be informed of the unconnected group member information and the reason for the disconnection (power off, no response, congestion, etc.). The circle is &&& &&& is currently busy If you want to reconnect while you are in use, press 1 and the group member number, and then disconnect each call. Press rupwon number) so that the group members can see the list of participants in the simultaneous call (S309, S310).

7 is a flowchart illustrating an event processing process of a simultaneous call mediation method according to the present invention.

After the simultaneous call is initiated by the process described with reference to FIGS. 4 to 6, the caller and the received group member are notified of the unconnected group member, the connection result, and a method of use (S309 and S310). And continuously checking whether a key is input by the called party (S401), and checking whether the input signal is a DTMF signal or a disconnect request signal (S402).

If the input signal is the disconnect request signal, check whether the disconnect request signal is input from the caller or the called party (S403), and if the input signal is input from the caller, disconnect all participants (S404) to simultaneously call the call. On the other hand, if it is input from the called party, only the connection of the called party is released (S405).

On the other hand, if the signal input in step S402 is a DTMF signal, the type of the DTMF signal is checked (S406), and processing for the request indicated by the signal is performed. That is, whether the signal requesting connection retries for unconnected group members (S407), whether the signal for requesting the release of a specific participant (S408), whether the signal requires a secret call with a specific participant (S409), Check whether it is a signal for requesting the release of the secret call (S410) and perform appropriate processing.

Here, the connection retry request and the request for disconnection of individual group members are preferably made to be attempted only by the sender, and the DTMF number corresponding to the request is preferably informed to the sender and the called party in advance by using the announcement. .

The process of processing each event by confirming that the DTMF signal or disconnect request signal is input from the calling party and the called party is continuously performed until the simultaneous call is released.

8 is a flowchart illustrating an unconnected call processing process in a simultaneous call mediation method according to the present invention.

In the group call attempt process shown in FIG. 6, if a normal incoming response is not received from the group member after attempting a call to all group members of the group selected by the caller (S303), the simultaneous call intermediation system 30 receives the call. Check the reason for the incapacity (S502).

If the called party's power is turned off (S503), it is requested to release the call attempt to the exchange in order to prevent the call attempt from being switched to the voice mail service (VMS) (S506). On the other hand, if the incoming call is not answered normally (S504) to stop the call attempt to the called terminal to be disconnected (S508). In this case, when the called party's terminal is a wireless terminal, it is preferable to check the response waiting time (S507) in order to prevent switching to the voice mail service (VMS) after a designated time elapses, and disconnect the connection before the waiting time is exceeded. Do. In addition, if the incoming call is not normally received due to an error of the called number, the busy state of the called party, the congestion of traffic, etc. (S505), the call is requested to be released by the exchange (S509).

In the present invention, it is possible to easily understand how to use the simultaneous call, the progress and the like by providing a simultaneous call service that a large number of participants participate by using the answering service. In addition, various disadvantages of the simultaneous call are improved by enabling a specific participant to exit or a secret call according to the DTMF signal generated during the concurrent call.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

As described above, the present invention not only shortens the time required for simultaneous call connection by simultaneously attempting a call to all the members of the group during the simultaneous call, but also sends out a method of using the simultaneous call, the progress, and the like as a guidement. It can alleviate the inconvenience and difficulty of using simultaneous calls.

In addition, by enabling a specific participant disconnection, a secret call, etc. according to the DTMF signal input from the user during the simultaneous call, problems and inconveniences that may occur in the simultaneous call with multiple participants can be improved.
