Description

  The present invention identifies a communication carrier to which a destination belongs by identifying a ringing sound pattern received in a destination call state in a telephone exchange device provided with a transmission line that is different for each communication carrier. The present invention relates to a telephone device that captures and transmits a corresponding outgoing call line according to the classification information of a communication carrier stored at the time of outgoing call.

  In a conventional telephone device, as a LCR (Least Cost Routing) function, it is determined whether or not the telephone number is for a mobile phone, and a transmission line is selected. This is shown in Patent Document 1 and the like.

JP 2000-41098 A

  However, in the conventional method, since it was determined whether or not to make a call through a mobile phone only with the telephone number dialed at the time of outgoing call, when there are multiple mobile phone carriers, each of these mobile phone carriers is individually It is not possible to efficiently use the communication cost reduction service such as the flat-rate call charge plan provided by each mobile phone carrier, especially among mobile phone carriers called MNP (Mobile Number Portability) today. With the telephone number transition system, the numbering system for each mobile phone carrier is broken, and it is not possible to identify the carrier by the phone number alone. For this reason, it has been difficult to accurately realize the LCR function for a plurality of mobile phone operators.

  An object of the present invention is to realize a means for more reliably specifying the cheapest carrier without relying only on a telephone number.

A telephone device having a communication carrier identification function of the present invention is a telephone device that can be connected to a telephone network of a plurality of communication carriers, and is a communication carrier that calls the communication partner when calling to the communication partner. A telecommunications carrier identifying means for detecting a paging tone from the telephone network and identifying a different paging beginning tone for each pre-stored telecommunications carrier to identify the telecommunications carrier; and Communication carrier information storing means for storing communication carrier classification information specifying a transmission line related to the communication carrier identified by the carrier identification means in association with the communication partner, and when communicating to the communication partner, telephone network selection hands for selecting the connection between the communication carrier sorting information telephone network of the telecommunications carrier if was stored in the communication service provider information storage means associated with If, have a, if the wireless service provider identified by the carrier identification means is different from the carrier's telephone network to which the own device is selected when originated to the communication party, a call to the communication partner And canceling the connection, selecting a connection with a telephone network of the same communication carrier as the communication carrier identified by the communication carrier identification means, and re-transmitting to the communication partner .

  According to the present invention, since the paging tone different for each communication carrier is identified in the state of being actually connected to identify the communication carrier, there is an effect that the communication carriers can be accurately distinguished.

  In addition, even if the automatic identification of the communication carrier fails or there is no call opening tone to be identified, the registration / change operation from the extension terminal can be provided to further improve the certainty.

FIG. 3 shows an example of the contents stored in the telephone directory memory or communication history memory according to the present invention. FIG. 4 is an operation flow of the control unit of the telephone device according to the present invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a block configuration of a telephone device according to an embodiment of the present invention. An extension terminal 60 is connected to the other terminals 11 to 13 via a telephone device 50 and telephone networks 21 to 25 according to the present invention. .

  After receiving the outgoing dial operation from the extension terminal 60 by the extension terminal control unit 540, the control unit 530 searches the dial (phone number) stored in the telephone directory memory 560 or the communication history memory 570, and sets the communication carrier classification information. To get.

  Next, the control unit 530 captures the outgoing lines 511 to 513 corresponding to the acquired carrier classification information, and the mobile phone adapters 41 and 43 or the IP phone adapter 44, the mobile phones 31 and 33, the IP phone network 24, and the like. A call is sent to the partner terminals 11 to 13 through the mobile phone networks 21 to 23.

  The mobile adapter 41 or the mobile adapter 43 connects an external line interface unit (in this embodiment, a transmission line) such as a PBX device and the mobile phone A31 or the mobile phone C33, and is a flat-rate call provided by the mobile phone carrier. Used to use rate plans.

  In recent years, a plan for reducing a call charge between a specific IP telephone service provider and a specific mobile telephone provider is also provided. The IP telephone adapter 44 connects the IP telephone network 24, and the IP telephone provider Used to use a reduced rate plan among the telephone operators offering it.

  If the communication carrier classification information cannot be acquired from the telephone directory memory 560 or the communication history memory 570 at the time of outgoing call, the normal outgoing line D515 and the telephone network D25 (the mobile phone adapter and the mobile phone are not connected) are connected. In this case, the call opening sound that can be heard on the communication path after the call is identified by the opening sound identifying unit 520, and the partner terminal is contracted based on the characteristics of the call opening sound. The mobile phone carrier is determined, and the carrier category information is stored in the telephone directory memory 560 or the communication history memory 570.

  As a result, according to the communication carrier classification information stored in the telephone directory memory 560 or the communication history memory 570 at the time of subsequent outgoing calls, the corresponding outgoing call line is captured, and between a predetermined flat-rate call charge plan or a specific telephone carrier. Realize outgoing connections using reduced pricing plans.

  In addition, when the mobile phone operator cannot be specified by the opening sound identification unit 520 described above, or when it is desired to set / change an arbitrary mobile phone operator, a specific operation for designating the communication operator is performed from the extension terminal 60 in the ringing state. This is detected by the communication carrier designation operation detection unit 550, and the control unit 530 may reflect the result in the corresponding storage location of the telephone directory memory 560 or the communication history memory 570.

  FIG. 2 is a diagram showing an example of a tone pattern in a call state for specifying a carrier, and is specified before an RBT (Ring Back Tone) that repeats a pause for about 2 seconds and repeats a pause for about 2 seconds. The carriers A to D are identified by the tone pattern.

  At this time, neither the tone pattern T230 of the telecommunications carrier C nor the tone pattern T240 of the telecommunications carrier D has an opening sound, and cannot identify which telecommunications carrier.

  In such a case, the telephone device 3 of the present invention displays from the extension terminal control unit 540 to the extension terminal 60 that the communication carrier cannot be specified and that the user needs to specify the communication carrier. The user of the extension terminal 60 performs a predetermined communication carrier designation operation, receives it by the communication carrier designation operation detection unit 550, and based on this designation operation, communicates in the telephone directory memory 560 or the communication history memory 570. Set the operator classification information.

  FIG. 3 is a diagram showing an example of storage contents stored in association with the memory of the telephone directory memory 560 or the communication history memory 570 according to the present invention, in which the carrier classification information (calling line designation information) corresponding to the telephone number is stored. It is remembered. (V571-V575)

  FIG. 4 is a diagram showing an operation flow of the control unit 530 of the telephone device 50 according to the present invention. This flow starts from a state where the telephone device 50 is turned on and waits for an outgoing operation from the extension terminal 60. (S5000). When the extension operation of the extension terminal 60 is detected by the extension control unit 540 (S5001, Y), the caller number is extracted, and the corresponding phone number is stored in the phonebook memory 560 using the extracted call phone number as a key, It is determined whether the corresponding telephone number is stored in the transmission history (communication history) memory 570 (S5002, S5003). If the corresponding telephone number is stored (S5002, Y, S5003, Y), further communication is performed. It is determined whether the operator identification information is stored (S5010).

  If the communication carrier identification information is stored (S5010, Y), the corresponding outgoing telephone number is stored in the transmission history (communication history) memory 570 (S5011), and the corresponding response is made based on the acquired communication carrier identification information. Any one of the transmission lines A to D is captured and transmitted to the intended destination (S5012).

  When the carrier identification information corresponding to the telephone directory memory 560 and the communication history memory 570 is not stored (S5002, N, S5003, N), and the communication carrier identification information from the telephone directory memory 560 and the communication history memory 570 Is not acquired (S5010, N), the outgoing telephone number is stored in the outgoing call history (communication history) memory 570 (S5021), and the outgoing line D (515) to be used when indeterminate is captured to obtain the target A call is sent to the other party (S5022).

  Subsequently, the opening sound identification unit 520 is enabled to identify the pattern of the calling opening sound coming from the telephone network (S5023), and when the communication carrier can be identified from the calling opening sound (S5024, Y), the outgoing call history ( The communication carrier identification information corresponding to the corresponding telephone numbers in the communication history memory 570 and the telephone directory memory 560 is stored (S5041, S5042).

  Next, the transmission to the other party is temporarily stopped (disconnected) (S5043), and any of the transmission lines A to D is captured according to the communication carrier classification information recorded in step 5041 and recorded in the transmission history. The call is re-sent to the latest destination telephone number (S5044).

  In step 5024, when the communication carrier cannot be identified (S 5024, N), the extension terminal control unit 540 displays to the extension terminal 60 a failure to identify the communication carrier and prompts specification by operation (S 5031). ), When information specifying a carrier category is received from the extension terminal by a button operation or the like (a specific operation is detected) (S5032, Y), the corresponding items in the transmission history (communication history) memory 570 and the telephone directory memory 560 Stores the carrier identification information corresponding to the telephone number (S5034, S5035).

  When the information specifying the carrier classification is not received from the extension terminal (no specific operation is detected) (S5032, N), waiting for the end of the call (S5051, Y) and entering the standby state (S5000) Return.

  After step 5012 and step 5044, the process waits for the end of the call (S5051, Y) and returns to the standby state (S5000).

  In this embodiment, in order to make the explanation easy to understand, the transmission line D is selected in S5022, and the transmission line D is temporarily disconnected in S5043. However, the present application is not limited to this. For example, any one of the transmission lines 511 to 513 is arbitrarily selected in S5022, and S5043 is S5043 only when the communication carrier of the arbitrarily selected transmission lines 511 to 513 is different from the communication carrier identified in S5023. The call may be disconnected with. Accordingly, there is an effect that it is not necessary to disconnect once when the communication carrier of the arbitrarily selected transmission line and the communication carrier of the other party are the same.
