Description

  The present invention relates to a method and a system for connecting between carriers in communication between communication terminals performed via a plurality of communication carriers (referred to as “carriers” in this specification), for example, telephone calls, and more. Specifically, the present invention relates to a connection method and system capable of reducing communication charges when performing communication via a plurality of carriers.

  The communication in the present invention includes any of analog, digital, IP, wired, and wireless, and the communication terminal includes various known types such as a fixed telephone, a mobile phone, a facsimile, a personal computer, and a PDA. Includes communication terminals.

  As an example of communication performed via a plurality of carriers, an example of performing communication by telephone will be described with reference to FIGS.

[Between mobile phones]
FIG. 2 is an example of a call performed between a plurality of mobile telephones via a plurality of mobile system carriers. When a telephone number assigned to the incoming telephone 51 is input by operating the outgoing telephone 31, The data output from the calling side telephone 31 reaches the POI (Point of interface) 40 via the switching network 30 of the calling side carrier, and is transmitted to the switching network 50 of the receiving side carrier via this POI 40 to be exchanged. The call is received by the receiving telephone 51 through 50 installation facilities.

  In the present specification, the “calling side” and the “calling side” both indicate the relationship at the time of the first call, and once between the communication terminals (phones in the illustrated example) 31, 51 After the connection is made, transmission and reception can be performed between the two sides.

[Between landline and mobile phone]
When a call is made between a fixed phone and a mobile phone, there are two conventional connection methods that are generally used: an example shown in FIG. 3 through a general public line network and an example shown in FIG. 4 through a dedicated line. There is.

(1) Example via public network In the example shown in FIG. 3, for example, the existing general public line of Nippon Telegraph and Telephone Corporation (hereinafter referred to as “NTT”) from the originating telephone 31 which is a fixed telephone. In this example, a call is made to the receiving side telephone 51, which is a mobile phone, via the switching network 30 of the outgoing side carrier, which is a network. When an 11-digit number bearing a number such as 090 indicating that the number is entered, this number information reaches the connection point with the switching network 50 of the called carrier that is a mobile system carrier through the above-mentioned NTT network. The incoming call carrier exchange network 50 searches for the mobile phone with its own subscriber, which is the incoming call side telephone 51, based on the signal received from this connection point. Call the machine and connect.

(2) Example via a dedicated line FIG. 4 is different from the example shown in FIG. 3 described above, in which the calling telephone 31 as a fixed telephone is connected to a dedicated line [for example, NTT Communications Corporation ( Hereinafter, it is an example of a case where it is subscribed to a dedicated line] 30 ′, which is called “NTT Communications”. Unlike the case shown in FIG. It is connected via a dedicated line 30 'to the exchange network 50 of the incoming carrier, which is a mobile system carrier.

Prior art document information of the present invention includes the following.
"Multi-media dictionary" published by Sangyo Kenkyukai (First edition: January 10, 1996) (p. 755, 756, 758)

  In the connection method configured as described above, all call charges are collected from the user by the calling carrier and distributed between the calling carrier and the receiving carrier. The breakdown is as follows: Different.

(1) Between mobile phones In the connection method shown in FIG. 2 described above, the call fee paid by the user is the network usage of the caller carrier (equipment cost from the caller phone to the POI) with respect to the call time. , The connection fee paid to the receiving carrier and the profit of the calling carrier, and this fee is determined by the calling carrier. In other words, the call charge setting right lies with the calling carrier.

  Note that the receiving carrier can receive a uniform connection fee regardless of which carrier is the calling carrier, as defined by the Ministry of Internal Affairs and Communications.

  In this way, when the connection fee is paid to the receiving carrier, the connection fee is settled in seconds, while the call charge for the user is charged in units of 30 seconds or 1 minute. ing.

  Therefore, even if the user ends the call in a time shorter than the above unit, the call charge for this is rounded up and charged accordingly, so the calling carrier collected from the user for the calling carrier There is a profit corresponding to the difference between the connection fee (30 seconds to 1 minute unit) and the connection fee (second unit) actually paid to the receiving carrier.

  As an example, when charging users in units of seconds and charging in units of 30 seconds, it is cheaper to pay about 40% when charging in units of seconds, and charging per minute. Theoretically, it is about 50% cheaper.

(2) Charge between fixed phone and mobile phone Even if a call is made from a fixed phone to a mobile phone, it is shown in FIG. 3 through a general public line network and in FIG. 4 using a dedicated line. Depending on the case, the billing method for the call charge is different and is as follows.

(2-1) In the case of going through a general line In the example shown in FIG. 3 through a general public line, the charge setting right is in the mobile system carrier on the receiving side, and the call charge set by this mobile system carrier is It is collected by the landline carrier that is the calling party.

  Then, the fixed-line carrier that is the caller who collects the call charge from the user subtracts the connection charge for the use of the company network from the collected call charge, and stores the rest in the mobile system carrier that is the callee.

  As an example, when the fixed-line carrier on the calling side is NTT and the mobile system carrier on the called side is NTT Docomo, Inc. (hereinafter referred to as “NTT Docomo”), NTT receives the information from the user. NTT collects a call charge of 70 yen / 3, and NTT subtracts 5.5 yen / 3 of the connection charge for using its own network, and pays the remaining 64.5 yen to NTT Docomo.

  In addition, when the mobile system carrier is KDDI Corporation (hereinafter referred to as “au”), NTT collects 90 yen / 3 minutes from users, and NTT collects 5.5 yen / 3 minutes from its own company. Deducted as a connection fee for network use, the difference of 84.5 yen is paid to au.

(2-2) Via a dedicated line In the example shown in FIG. 4 that connects to a mobile system carrier on the receiving side via a dedicated line, the fixed carrier 43 laid with a dedicated line has a right to set a fee. As an example, if the fixed line on the fixed telephone side is laid by NTT Communications and the user makes a call to a NTT DoCoMo mobile phone, NTT Communications A call charge of 20 yen / minute is charged and collected, and a connection charge of 0.206 yen / second is paid to NTT DoCoMo.

  Regardless of the above connection method, the telecommunications carrier invests a huge amount of capital regardless of the presence of users, lays a nationwide network, establishes a large number of exchanges, and then secures users. I'm struggling.

  For this reason, regarding the setting of call charges, a substantial risk burden is added to the actual call cost, and the burden on the part of the poor operation rate due to excessive facilities is also reflected in the call charge, which is charged to the user. If the telecommunications carrier has the right to set a call charge, the call charge paid by the user is expensive.

  Therefore, the present invention has been made to solve the above-described drawbacks in the prior art, and by connecting the switching networks of a plurality of carriers through a connection exchanger having a dedicated line, this is done. The purpose of enabling the connection between the sending and receiving sides without causing the cost of the risk burden on the actual call cost to be added to the call charge by generating the right to set the charge for the installer of the connection exchange And

  In the connection system, the communication record between the transmission side communication terminal 31 and the connection exchange 10 and the communication record between the connection exchange 10 and the reception side communication terminal 51 are recorded in the connection exchange 10, respectively. Means can be provided (claim 8).

  Further, when calling the incoming call side communication terminal 51, a number for calling the connection switch 10 via the equipment 42 of the incoming call side fixed telephone carrier B and the incoming call side dedicated line 22 is designated as the incoming call side communication terminal. It is preferable that means for notifying 51 is provided in the connection exchanger 10 (claim 9).

Furthermore, a plurality of channels are provided in the incoming side dedicated line 22, and the telephone number of each outgoing side communication terminal 31 registered in advance in the connection exchange 10 and the incoming side dedicated line assigned to the number are connected.

  The calling carrier can be a general public line carrier, and the called carrier can be a mobile carrier.

  According to the connection method and connection system between a plurality of carriers of the present invention having the above-described configuration, the following effects can be obtained.

(1) Since the switching networks 30 and 50 of a plurality of carriers can be connected by the connection switch 10 via the dedicated lines 21 and 22, a plurality of carriers can be connected without going through the existing connection points described as the prior art. The connection between the carrier exchange networks 30 and 50 could be made.

  As a result, the right to set a call charge between the calling communication terminal 31 and the connection exchange 10 and between the connection exchange 10 and the receiving communication terminal 51 is generated by the installer of the connection exchange 10, thereby enabling a substantial call. It was possible to provide a connection exchange method and a connection exchange system that enable connection between the sending and receiving sides without adding the cost of risk for the cost to the call charge.

(2) The case where the connection switch 10 records the communication record between the transmission side communication terminal 31 and the connection exchange 10 and the communication record between the connection exchange 10 and the reception side communication terminal 51, respectively. In addition, it is possible to easily settle the connection fee with each carrier, charge the user, etc., in addition to the case where the method and system of the present invention are used as a private network for a company, for example, It is convenient for the second type communication carrier and the like.

(3) Means for storing the telephone number of each outgoing communication terminal 31 registered in advance in the connection exchange 10 and the channel of the incoming dedicated line 22 assigned to the number in association with each other. A dedicated line corresponding to the telephone number of the caller communication terminal 31 that made the call via the callee fixed line carrier equipment 42 to the connection switch 10 when calling the callee communication terminal 51 In the case where the dial-in number for making a call to the channel 22 is set in front of the telephone number of the calling communication terminal 31, for example, or when only the number is notified, the communication is temporarily ended. Even if it is necessary to make a call (callback) from the incoming communication terminal 51 to the outgoing communication terminal 31 later, this can be easily performed based on the incoming call history, etc. Burden that occurs in less.

  In this case, when a call is made to the dial-in number via the receiving communication terminal 51, it may be requested to input the telephone number of the calling communication terminal 31 following the dial-in number. Further reducing the burden on the user by transferring a call from the receiving communication terminal 51 to the connection switch 10 to the telephone number of the calling communication terminal 31 corresponding to the channel of the dial-in number. I was able to.

  When the calling carrier is a carrier for a general public line and the receiving carrier is a carrier for a mobile system, the call charge between fixed and mobile phones with a relatively high call charge is greatly reduced. I was able to.

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

  In the embodiment described below, the calling carrier is described as a carrier of a general public line such as a general landline telephone, and the receiving carrier is described as a mobile system carrier such as a mobile phone. The communication mode to be connected is not particularly limited, and as described above, various types such as digital, analog, IP, wired, and wireless, and combinations thereof can be targeted, and the communication mode to be connected The combinations are not limited to these.

  Further, in the following embodiment, the transmission side communication terminal 31 is described as a fixed telephone, and the reception side communication terminal 51 is described as a mobile phone. Similarly, various known communication terminals can be used, The present invention can be applied to a case where a facsimile, personal computer, PDA, or the like is used as a communication terminal in addition to a fixed phone and a mobile phone in a narrow sense.

  In FIG. 1, reference numeral 1 denotes the whole complex network via a plurality of carriers to which the connection method of the present invention is applied. In this complex network 1, a fixed telephone as a caller communication terminal 31, and a receiver telephone Communication between the mobile telephones 51 is possible.

  The composite network 1 enables communication via a plurality of carriers as described above, and the transmission side carrier exchange network 30 to which the transmission side communication terminal 31 is connected (in the example of this embodiment, “ General public line switching network ") and a receiving side carrier switching network 50 (" mobile system carrier switching network "in the example of the present embodiment) in which a mobile phone as the receiving side communication terminal 51 is wirelessly connected. ing.

  A facility 41 of a calling side fixed telephone carrier A is connected to the switching network 30 of the calling side carrier, and a facility 42 of a receiving side fixed telephone carrier B is connected to the switching network 50 of the receiving side carrier. The connection switch 10 connected to the equipment 41 of the calling-side fixed telephone carrier A and the equipment 42 of the receiving-side fixed telephone carrier B via dedicated lines 21 and 22 such as PRI, for example. I have.

  In this way, the connection exchange 10 can be connected between the equipment 41 of the calling-side fixed telephone carrier A and the equipment 42 of the receiving-side fixed telephone carrier B through the dedicated lines 21 and 22. The installer of the device 10 can obtain the right to set a call charge between the calling fixed telephone 31 and the connection switch 10 and a call charge between the connection switch 10 and the call receiving telephone 51.

  For example, the connection between the calling telephone 31 and the connection exchange 10 is performed by connecting the telephone number of the receiving telephone 51 to the switching network 30 of the calling carrier, the equipment 41 of the fixed telephone carrier A and the dedicated line 21 of the calling side. By adding a number (for example, a four-digit number starting with 00) set in advance as a number for requesting connection to the connection switch 10 via the dial, for example, the city of the switching network 30 of the calling-side carrier The internal switching center may determine that the dialed number is a call to be sent via the route and secure a line to the connection switch 10. Therefore, unlike the connection method described in the prior art, connection via a connection point is not performed.

  The connection to the connection exchange 10 performed in the originating carrier switching network 30 is a four-digit number beginning with 00 at the beginning of the telephone number when making a call or the like via a known NCC or the like. It is possible to process by the same method as in the case of dialing by adding.

  In the case where the service by the connection method and connection system of the present invention is to be provided to a pre-registered user or the like, the call is made in advance on the caller telephone 31 or the PBX of the caller telephone. It may be configured to reduce the burden on the user by setting to make a call with a unique number added.

  This connection exchange 10 uses the receiving side telephone line 51 and the receiving side fixed telephone carrier B equipment 42 to receive the telephone number of the receiving side telephone 51 received via the calling carrier switching network 30. And the connection time between the calling telephone 31 and the connection exchanger 10 and between the connection exchanger 10 and the incoming telephone 51 is stored as a communication record. When a line is secured between the calling telephone 31 and the connection switch 10 as described above, counting of communication time between the calling telephone 31 and the connection switch 10 is started. At the same time, the connection switch 10 receives the telephone number of the receiving side telephone 51 input in the outgoing side telephone 31 and the received number of the incoming side mobile telephone 51 is received by the incoming side dedicated line 22 and the incoming line. And outputs the switching network 50 of the called party carrier through the equipment 42 side fixed telephone carrier, a call incoming side mobile phone 51 corresponding to the No. 該番.

  Then, when a call is started by securing a line between the connection switch 10 and the call receiver 51 by on-hooking of the call receiver 51, a call time count between the connection switch 10 and the call receiver 51 is increased. Be started. The two communication times and the like are counted and recorded until the call between the outgoing and incoming telephones 31 and 51 is completed.

  Contrary to the above example, in the configuration shown in FIG. 1, when the mobile phone is set as the calling side phone and the fixed phone is set as the receiving side phone, the operation reverse to the above is performed, and If the telephone number of the fixed telephone to be called is input following the input of the number assigned to the exchange, the telephone call between the fixed telephone and the mobile telephone can be performed by the reverse operation to the above-described operation. Also good.

  The connection exchange 10 described above can be provided with various functions so that the above-described call can be performed more conveniently, and the caller side telephone 51 (fixed telephone) is notified of the number. 1, before the telephone number of the calling side telephone 31, a path opposite to the path shown in FIG. 1, that is, from the incoming side telephone 51 to the incoming side carrier switching network 50 and the incoming side fixed telephone carrier B. A number necessary for making a call to the connection exchange 10 via the equipment 42 and the incoming line 22 can be added.

  As a result, even after a call based on a call from the calling side telephone 31 is terminated, a so-called “call back” is required to call the calling side telephone 31 again from the receiving side telephone 51. The user can easily connect to the connection exchanger 10 by making a call to the displayed number based on the incoming call history or the like.

  Such a callback is performed by the incoming side telephone 51 to the outgoing side telephone 31 based on voice guidance or the like issued from the connection exchange 10 after the line between the incoming side telephone 51 and the connection exchange 10 is secured. It may be configured to input a number. Preferably, however, the number necessary for connection from the incoming side telephone 51 to the connection switch 10 is added before the telephone number of the outgoing side telephone 31 as described above. Then, a number notification is output, and both numbers are continuously output from the receiving side telephone 51 so that connection to the connection exchange 10 can be performed. Alternatively, the connection switch 10 may be configured to receive the number of the receiving telephone 31 that is output after the necessary number.

  Thereby, based on the telephone number of the fixed telephone 31 that has been received, the junction exchange 10 that has received the telephone number is the outgoing side dedicated line 21, the equipment 41 of the outgoing side fixed telephone carrier A, and the outgoing side carrier switching network 30. The call may be made to the caller telephone 31 via the telephone.

  In the embodiment described above, the connection system of the present invention has been described as being able to be used for unspecified users. However, the connection method of the present invention has been registered in advance. It can also be a service provided only to a specific user.

  As an example of such a usage method, an example will be described in which communication between a fixed telephone and a mobile phone is performed in the same manner as described above, and registration or the like is performed in advance with respect to a fixed telephone contractor.

  In this case, the PRI channel number (PRI dial-in number) of the incoming side dedicated line 22 between the connection switch 10 and the equipment 42 of the incoming side fixed telephone carrier B is assigned to each registered telephone number of the outgoing side telephone 31. In addition, a storage means for storing the PRI channel number and the telephone number of the caller telephone 31 assigned to the PRI channel number in association with each other is provided in the connection exchange 10 described above.

  The connection exchange 10 is further provided with a number notification means. When the number notification means makes a call from the calling telephone 31 of the number stored in the storage means, the number is stored according to the stored correspondence. Calls the PRI dial-in number corresponding to the number notification of the calling side telephone 31 and adds the PRI dial-in number in front of the telephone number of the calling side telephone 31 or only this PRI dial-in number. As the number display of the telephone 31, it is output to the receiving telephone 51.

  In the case where the number notification means outputs only the PRI dial-in number of the receiving side dedicated line 22, when there is a callback from the receiving side telephone 51 as described above, this is indicated by the PRI dial-in number. The connection exchange 10 may further be provided with transfer means for determining that the call is for the fixed telephone 31 assigned to the number and transferring the call to the corresponding fixed telephone 31 number.

  If the number notification means outputs the PRI dial-in number together with the telephone number of the caller telephone 31, the connection exchange 10 sends the caller telephone output after the PRI dial-in number. The point that can be configured to receive the number 31 and make a call to the received number is the same as described above.

  By using the connection system between a plurality of carriers of the present invention configured as described above, a call performed via a plurality of carriers is performed through a route of public-exclusive-connection exchange-exclusive-public. As described in the related art, the connection via the connection point is not performed.

  Therefore, both the right to set a call charge from the fixed telephone 31 to the connection switch 10 and the right to set the call charge from the connection switch 10 to the receiving telephone 51 exist in the installer of the connection switch 10. It becomes.

  By using the connection system of the present invention configured as described above, for example, a charge for making a call from a fixed telephone to a mobile phone is as follows: caller carrier (NTT as an example), fixed telephone carrier B ( The actual cost is about 11.6 to 13.5 yen / minute, including the connection fee to pay for the mobile system carrier and the maintenance cost of the dedicated line, and the call charge for au call via NTT is 30 yen. / Min, compared to 20 yen / min, which is the NTT Docomo call charge via NTT Communications.

  In addition, even if the service is provided by the type 2 communication carrier, the connection fee for each carrier is set as described above by charging the user in units of 30 seconds or 1 minute. Is settled in seconds, so if the difference is taken into consideration, the call charge can be provided at about 11.5 yen / 30 seconds and 16.1 yen / 1 minute. This can be made cheaper than the call charge by any method.

  In addition, by adding the various functions as described above to the connection exchanger 10, there is no complication when the user uses it.

  The connection method and connection system between a plurality of carriers configured as described above can be used as, for example, a private network for a company or the like, and provide a communication service to a large number of specified or unspecified users. It can be used in the provision of services of type 2 communication carriers.
