JP5999763B2 - Subscriber accommodation call control device, call restriction method for subscriber accommodation call control device, and program - Google Patents

Description

  The present invention relates to a subscriber accommodation call control device, a call restriction method for a subscriber accommodation call control device, and a program.

  For example, when a voice communication terminal such as a telephone used by a user communicates with a voice communication terminal such as another telephone via a predetermined network such as a telephone network or an IP network, The voice communication terminal exchanges call information with the subscriber accommodation call control server (or the subscriber accommodation call control device) constituting the voice communication network, thereby establishing a call.

  In a conventional subscriber accommodation call control server, for example, for the purpose of confirming safety in an emergency such as a large-scale disaster, when a large number of calls from a voice communication terminal used by an accommodation subscriber occurs, a connected call Congestion of the subscriber accommodation call control server is caused by the occupation of the line due to the call or the re-call of the accommodated subscriber who is not connected to the call. In such a state, many voice communication terminals cannot communicate.

  In order to avoid such a situation, for example, in response to a command from an upper station such as an operation center that manages the mobile phone network, the call information stored in the home memory station is referred to. Thus, there is a technique that can avoid a state in which calls cannot be made between many voice communication terminals even when the line is congested (for example, Patent Document 1).

  Also, for example, a management service device is newly provided, and its control is used to avoid a state in which calls cannot be made between many voice communication terminals by disconnecting the line when a predetermined time elapses when the line is congested. There is a technique (for example, Patent Document 2).

  In addition, for example, in response to a command from an upper station such as an operation center that manages a mobile phone network, a call from a priority telephone number terminal group is preferentially connected, and a call other than the priority telephone number terminal group is connected. There is a technique for avoiding a state in which a telephone call cannot be made between many voice communication terminals, for example, in which the communication restriction time is determined by the number of lines and a required call loss rate (for example, Patent Document 2).

  Hereinafter, an information providing system according to an embodiment of the present invention will be described with reference to FIGS.

  An overview of call control in a communication system will be described with reference to FIG.

  For example, voice communication terminals 1-1, 1-2,..., 1-n (hereinafter referred to as voice communication terminals 1) of accommodating subscribers such as telephones are connected via the subscriber accommodating call control device 2. For example, it is connected to an IP network NGN (Next Generation Network), the Internet, or a network 3 such as a telephone network.

  The voice communication terminal 1 can be identified by a SIP (Session Initiation Protocol) address, an IP address, a MAC (Media Access Control) address, or a telephone number.

  In some cases, a subscriber accommodation call control server is installed in place of the subscriber accommodation call control device 2, but the subscriber accommodation call control server or the subscriber accommodation call control device may be the following. Therefore, in the following description, the subscriber accommodation call control device 2 will be referred to.

  When the voice communication terminal 1 requests to start communication with a voice communication terminal such as another telephone (not shown) via the network 3, first, the voice communication terminal 1 on the caller side joins the voice communication network. The call is established by exchanging call information with the person accommodating call control device 2.

  The subscriber accommodation call control device 2 is in a state where a large number of calls are made in addition to the conventional functions such as the above-described normal call control and management of the voice communication terminal 1 held by the accommodated subscriber. If a problem occurs, the call time is managed and the call connection request is accepted, so that as many of the voice communication terminals 1 that are accommodated and controlled as subscribers are given equal opportunities to talk. Can be.

  Next, with reference to FIG. 2 and FIG. 3, a function for giving a call opportunity to as many of the voice communication terminals 1 that are accommodated and controlled by the subscriber accommodation call control device 2 as subscribers will be described. To do.

  First, referring to FIG. 2, the first function is to equally give the opportunity for a call to as many of the voice communication terminals 1 that are accommodated and controlled by the subscriber accommodation call control device 2 as subscribers. The call disconnection process will be described.

  The subscriber's voice communication terminal 1 makes a call connection request to the subscriber accommodation call control device 2 (S1 in the figure), and the call is established by the subscriber accommodation call control device 2, and the subscriber's voice communication terminal 1 and the like. When a call is in progress with the voice communication terminal (S2 in the figure), the subscriber accommodation call control device 2 executes call disconnection (S3 in the figure) when the call time reaches a certain level. By disconnecting, line occupation can be suppressed.

  Next, referring to FIG. 3, the second function for equally giving the opportunity of a call to as many of the voice communication terminals 1 that are accommodated and controlled by the subscriber accommodation call control device 2 as subscribers. A call request reception control process will be described.

  The subscriber accommodation call control device 2 that controls the call of the voice communication terminal 1 of the subscriber who is in a call state with another voice communication terminal (S11 in the figure), after the call is disconnected, for a certain time (in the figure) In response to a call connection request (S12, S14 in the figure) issued from the same voice communication terminal 1 issued before elapse of t), the call connection is not accepted and an error response is returned to the voice communication terminal 1. (S13 and S15 in the figure) are executed. Then, the subscriber accommodation call control device 2 allows the call connection processing in response to the call connection request (S16 in the figure) of the voice communication terminal 1 after a predetermined time (see t in the figure) has elapsed after the call is disconnected. Then, it is possible to make a call (S17 in the figure). As a result, it is possible to provide as many voice communication terminals 1 as possible with a call while suppressing congestion.

  FIG. 4 is a functional block diagram of the subscriber accommodation call control device 2.

  The subscriber accommodation call control device 2 may have other functions necessary as the subscriber accommodation call control device in addition to the functions described with reference to FIGS. 2 and 3. For convenience of explanation, only the portions related to the functions described with reference to FIGS. 2 and 3 will be described, and the general subscriber accommodation call control apparatus has the conventional functions. This is not described in detail for the other parts.

  The subscriber accommodation call control device 2 includes a call connection request acquisition unit 11, a mass call handling processing unit 12, and a call connection / call disconnection processing unit 13.

  The call connection request acquisition unit 11 receives a call connection request from the voice communication terminal 1, and from which voice communication terminal 1 the call connection request is generated in the call connection execution control unit 23 of the mass call response processing unit 12. , And various other information indicating to which other voice communication terminal a call connection request has occurred. The information for identifying the voice communication terminal 1 or other voice communication terminals includes, for example, an SIP address, an IP address, a MAC address, or a telephone number.

  The mass call response processing unit 12 includes a mass call response processing start instruction information acquisition unit 21, a timer 22, a call connection execution control unit 23, a voice communication terminal information management unit 24, and a call disconnection control unit 25. For example, when a large number of call requests are expected to occur as represented by a disaster such as a large-scale earthquake, the processing described with reference to FIGS. 2 and 3 is executed.

  For example, when a large number of call requests are expected to occur, such as when a disaster such as a large-scale earthquake occurs, the mass call response processing start instruction information acquisition unit 21 automatically or Is received, and the call connection execution control unit 23 is notified. In addition, the mass call response process start instruction information acquisition unit 21 receives an instruction to end the mass call response process automatically or by an administrator input or the like, and notifies the call connection execution control unit 23 of the command.

  The timer 22 may count the current time, or may count the absolute time that is common to each part in the subscriber accommodation call control device 2, not the current time.

  When the call connection execution control unit 23 has not received a mass call response process start instruction information acquisition unit 21 from the mass call response process start instruction information acquisition unit 21, the call connection execution control unit 23 is based on various information notified from the call connection request acquisition unit 11. Then, the call connection / call disconnection processing unit 13 is controlled to establish a call between the voice communication terminal 1 that has generated the call connection request and another desired voice communication terminal.

  When the call connection execution control unit 23 receives a notification of a start instruction for a large volume call response process from the large volume call response process start instruction information acquisition unit 21, the voice communication terminal information management unit 24 manages the call connection execution control unit 23 at any time. The call start time of all the voice communication terminals 1 in the call state is referred to, and the timer 22 is referred to detect the voice communication terminal 1 that has passed a predetermined time from the call state, and call disconnection control is performed. The unit 25 is requested to execute call disconnection of the voice communication terminal 1 after a predetermined time has elapsed from the call state.

  In addition, the call connection execution control unit 23 receives a new call connection request from the call connection request acquisition unit 11 in a state where the notification of the start command for the large number of call response processing is received from the mass call response processing start instruction information acquisition unit 21. In response to the notification, the voice communication terminal information management unit 24 is referred to based on various information notified from the call connection request acquisition unit 11 to obtain information on the call end time of the voice communication terminal 1 that requested the call connection. At the same time, referring to the timer 22, it is determined whether or not a predetermined time has elapsed since the end of the previous call of the voice communication terminal 1 that requested the call connection.

  When the predetermined time has not elapsed since the call before the call of the voice communication terminal 1 that requested the call connection, the call connection execution control unit 23 returns an error response to the corresponding voice communication terminal 1 and performs the call connection. Do not establish.

  As described above, the connection control function that measures the time during which reconnection is possible and controls the connection is performed on the calling terminal in the previous call, thereby suppressing re-calling immediately after disconnection. This is effective in converging congestion.

  On the other hand, when a predetermined time has elapsed since the end of the previous call of the voice communication terminal 1 that requested the call connection, the call connection execution control unit 23 controls the call connection / call disconnection processing unit 13, When a call is established between the voice communication terminal 1 that has issued the call connection request and a desired other voice communication terminal, and when a call state is established, the timer 22 is referred to obtain the call state start time. Then, the call connection execution control unit 23 supplies the voice communication terminal information management unit 24 with information for identifying the voice communication terminal 1 that has issued the call connection request and information indicating the call start time, and corresponding voice communication. Control is performed so that information indicating the state of the terminal changes from “non-call” to information indicating “call”, and information indicating the time at which the state transitions in this way is updated.

  Further, the call connection execution control unit 23 performs normal call disconnection processing or call disconnection control in a state in which the mass call response processing start instruction information acquisition unit 21 receives a notification of a start command for mass call response processing. Under the control of the unit 25, the call connection / call disconnection processing unit 13 notifies the notification that one of the voice communication terminals 1 of the subscriber accommodated in the subscriber accommodation call control device 2 has been terminated. , The call end time is obtained with reference to the timer 22. Then, the call connection execution control unit 23 supplies the voice communication terminal information management unit 24 with information for identifying the voice communication terminal 1 that has finished the call and information indicating the call end time, and the corresponding voice communication terminal Control is performed so that the information indicating the state changes from “call” to “non-call”, and the information indicating the time when the state transitions is updated.

  The voice communication terminal information management unit 24 includes all the identification information of the voice communication terminals 1 owned by the subscribers accommodated in the subscriber accommodation call control device 2 and the state of those voice communication terminals 1, that is, the call state. Information indicating whether or not there is and the time when the state transitions to a call or non-call is recorded and managed.

  Even in the conventional subscriber accommodation call control device, all the identification information of the voice communication terminal possessed by the subscriber accommodated in the subscriber accommodation call control device is recorded, but the subscriber accommodation call control device 2 In addition to the identification information, the voice communication terminal information management unit 24 associates the identification information with information indicating whether each voice communication terminal 1 is in a call state, and calls or non-calls. Information indicating the time when the state transitions is recorded and managed.

  That is, the voice communication terminal information management unit 24 determines whether the voice communication terminal 1 of the subscriber accommodated in the subscriber accommodation call control device 2 has a call state based on the control of the call connection execution control unit 23. The identification information indicating the voice communication terminal 1 that has become or has ended the call and the information indicating the call start time or the call end time are acquired, and from the “call” state to the “non-call” state, or The information indicating the state held corresponding to the identification information of the voice communication terminal 1 whose state has changed from the “non-call” state to the “call” state is changed, and further information indicating the time at which the state has changed Update and record, and keep the recording state until the next update.

  Since there are only two types of states of the voice communication terminal 1, a “call” state and a “non-call” state, for example, all voice communication accommodated as a subscriber only by turning on and off a 1-bit flag. The state transition of the terminal 1 can be easily managed. In addition, since the time when the state transition is made is updated and recorded, it is not necessary to manage the call end time and the call start time separately.

  The call disconnection control unit 25 receives a request for execution of call disconnection of the predetermined voice communication terminal 1 from the call connection execution control unit 23, controls the call connection / call disconnection processing unit 13, and determines a predetermined voice in a call state. Call disconnection of the communication terminal 1 is executed.

  Then, the call connection / call disconnection processing unit 13 executes call connection establishment or call disconnection processing based on the control of the call connection execution control unit 23 or the call disconnection control unit 25. Further, when the call connection establishment / call disconnection processing unit 13 executes the call connection establishment or call disconnection processing, the call connection / call disconnection processing unit 13 notifies the call connection execution control unit 23 that the call connection / call disconnection processing has been executed. .

  Next, processing executed by the subscriber accommodation call control device 2 will be described with reference to the flowcharts of FIGS. 5 and 6.

  The mass call response processing start instruction information acquisition unit 21 of the mass call response processing unit 12 is, for example, expected to generate a large number of call requests as represented by a disaster such as a large-scale earthquake. Since a start command for a large number of call response processing is received automatically or by an administrator input or the like, in step S31, the call connection execution control unit 23 of the large number of call response processing unit 12 performs the large number of call response processing. It is determined whether or not a notification of a start command for mass call response processing has been received from the start instruction information acquisition unit 21.

  If it is determined in step S31 that the notification of the start command for the mass call response process has not been received, in step S32, the subscriber accommodation call control device 2 executes a normal call process, Returning to S31, the same processing is executed.

  That is, when the call connection request acquisition unit 11 receives a call connection request from any of the voice communication terminals 1 accommodated as a subscriber, the voice communication terminal that generated the call connection request to the call connection execution control unit 23 1 and various other information indicating to which other voice communication terminal a call connection request has occurred are notified. The call connection execution control unit 23 controls the call connection / call disconnection processing unit 13 to establish a call between the voice communication terminal 1 that has generated the call connection request and another desired voice communication terminal. Then, the call connection execution control unit 23 is in a state waiting for notification of the start command of the mass call response process from the mass call response process start instruction information acquisition unit 21 until the start command of the mass call response process is notified. Repeat the same process.

  If it is determined in step S31 that the notification of the start command for the large volume call response process has been received, in step S33, the call connection execution control unit 23 determines that the voice communication terminal information management unit 24 of the large volume call response processing unit 12 Reference is made to the call start times of all the voice communication terminals 1 in the call state that are being managed, and the timer 22 of the mass call handling processing unit 12.

  In step S34, the call connection execution control unit 23 determines whether there is a voice communication terminal 1 for which a predetermined time has elapsed from the call state.

  If it is determined in step S34 that there is no voice communication terminal 1 for which a predetermined time has elapsed since the call state, the process proceeds to step S37 described later.

  If it is determined in step S34 that there is a voice communication terminal 1 for which a predetermined time has elapsed from the call state, in step S35, the call connection execution control unit 23 sends a call disconnection control unit 25 of the call connection execution control unit 23 to the call disconnection control unit 25. The voice communication terminal 1 is requested to execute call disconnection after a predetermined time has elapsed from the call state. The call disconnection control unit 25 controls the call connection / call disconnection processing unit 13 to execute the call disconnection of the voice communication terminal 1 after a predetermined time has elapsed from the call state.

  When call disconnection is executed, for example, a message “The line will be disconnected after the remaining xx minutes (or xx seconds) because the congestion of the line is expected” may flow in advance. . Furthermore, it goes without saying that a message such as “Cannot call again for xx minutes after disconnecting the line. Thank you for your cooperation.”

  In step S36, the call connection execution control unit 23 instructs the voice communication terminal information management unit 24 to identify the voice communication terminal 1 that has finished the call, and information indicating the call end time obtained by referring to the timer 22. Supply. The voice communication terminal information management unit 24 changes the information indicating the “call” state held corresponding to the voice communication terminal 1 that has ended the call to information indicating the “non-call” state, and further, the call end time. Is recorded, and the recorded state is maintained until the next information update.

  In step S34, when it is determined that there is no voice communication terminal 1 for which a predetermined time has elapsed from the call state, or after the process of step S36 is completed, in step S37, the call connection request acquisition unit 11 calls the call connection request. It is determined whether or not an error has occurred.

  If it is determined in step S37 that a call connection request has not occurred, the process proceeds to step S44 described later.

  If it is determined in step S37 that a call connection request has occurred, in step S38, the call connection request acquisition unit 11 sends to the call connection execution control unit 23 from which voice communication terminal 1 the call connection request has been generated. , And various other information indicating to which other voice communication terminal a call connection request has occurred. The call connection execution control unit 23 refers to the voice communication terminal information management unit 24 based on the various information notified from the call connection request acquisition unit 11, and obtains information on the call end time of the voice communication terminal 1 that requested the call connection. And the timer 22 is referred to.

  In step S39, the call connection execution control unit 23 determines whether or not a predetermined time has elapsed since the end of the call of the voice communication terminal 1 that requested the call connection.

  In step S39, when it is determined that the predetermined time has not elapsed since the end of the call of the voice communication terminal 1 that requested the call connection, in step S40, the call connection execution control unit 23 sends the corresponding voice communication terminal 1 to the corresponding voice communication terminal 1. Returns an error response and does not establish a call connection. After the process of step S40 ends, the process proceeds to step S44 described later.

  At this time, it is preferable that a message such as “After the line is disconnected, the call cannot be repeated for xx minutes. Please try again after a predetermined time has passed.

  If it is determined in step S39 that a predetermined time has elapsed since the end of the call of the voice communication terminal 1 that requested the call connection, in step S41 the call connection execution control unit 23 calls the call connection / call disconnection processing unit 13. To establish a call between the voice communication terminal 1 that has generated the call connection request and a desired other voice communication terminal.

  In step S42, the call connection execution control unit 23 determines whether a call between the voice communication terminal 1 that has generated the call connection request and another desired voice communication terminal is started.

  If it is determined in step S42 that a call between the voice communication terminal 1 that has issued the call connection request and the desired other voice communication terminal has not started, the process proceeds to step S44 described later.

  If it is determined in step S42 that a call between the voice communication terminal 1 that has generated the call connection request and the desired other voice communication terminal has started, the call connection execution control unit 23 sets the timer 22 in step S43. The call state start time is obtained by reference, and the voice communication terminal information management unit 24 is supplied with information for identifying the voice communication terminal 1 that generated the call connection request and information indicating the call start time. The voice communication terminal information management unit 24 changes the information indicating the “non-call” state held corresponding to the voice communication terminal 1 that started the call to information indicating the “call” state, and further, the call start time Is recorded, and the recorded state is maintained until the next information update.

  The mass call response processing start instruction information acquisition unit 21 receives a command to start mass call response processing, for example, automatically or by an administrator input, and notifies the call connection execution control unit 23 of the command. Has been made. Therefore, if it is determined in step S37 that a call connection request has not occurred, after the process of step S40 is completed, in step S42, the voice communication terminal 1 that generated the call connection request and another desired voice communication terminal. When the call connection execution control unit 23 determines in step S44 that the call connection execution control unit 23 has not started a large number of calls, the call connection execution control unit 23 receives a large number of outgoing calls from the mass call corresponding processing start instruction information acquisition unit 21 in step S44. It is determined whether or not notification of a call response processing end command has been received.

  In step S44, when it is determined that the notification of the end instruction for the large volume call response processing has not been received, the processing returns to step S33, and the subsequent processing is repeated.

  In step S44, when it is determined that the notification of the end instruction for the mass call response process has been received, the process returns to step S31, and the subsequent processes are repeated.

  By such processing, for example, in the case of an emergency such as a large-scale disaster, even if a large number of calls occur and congestion is assumed, the call time of the voice communication terminal 1 held by the accommodating subscriber Since the re-call interval is controlled, the call volume for each accommodated subscriber can be leveled, and a call service can be provided to many subscribers.

  The subscriber accommodation call control device 2 described above is accommodated by using the information for identifying the voice communication terminal 1 held by the accommodated subscriber, which is also managed in the conventional subscriber accommodation call control device. The voice communication terminal 1 possessed by the subscriber is controlled so that the call time is within a predetermined time, and the call connection establishment interval is controlled to be a predetermined time or more. That is, the subscriber accommodation call control device 2 further associates the identification information of the voice communication terminal 1 with information indicating whether the voice communication terminal 1 is in a call or non-call state, Information indicating the time when the non-call state transitions can be recorded / updated, and the call time and re-call interval of the voice communication terminal 1 can be controlled based on the information.

  Thus, in the subscriber accommodation call control device 2, using the function of the conventionally used device and the information managed in the past, the conventional subscriber accommodation call control device and the voice call system, By adding simple information management, congestion can be suppressed without complicated system changes.

  The series of processes described above can be executed by hardware or can be executed by software. When a series of processing is executed by software, a program constituting the software executes various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a program recording medium in a general-purpose personal computer or the like.

  The program executed by the computer may be a program that is processed in time series in the order described in this specification, or in parallel or at a necessary timing such as when a call is made. It may be a program for processing.
