Description

  The present invention recognizes an event that a mobile phone user has changed a mobile phone company using number portability (carrier change) as meaningful marketing information, and quickly detects information on carrier changes that occur daily.・ New technologies in the telephony field.

  The fact that a certain mobile phone user changed the carrier due to the number portability is natural default information for the carrier before and after the change. However, there has been no way for a user who is involved in the change and a third party other than the carrier to know specific information that the carrier has been changed from one carrier to another at a certain mobile phone number.

  The inventor of the present application considers that the specific information of the career change that occurs every day among a huge number of mobile phone users is meaningful as marketing information, and uses a computer connected to ISDN to We have developed a computing technology that detects carrier changes based on telephone numbers.

=== Creation process of invention ===
As explained in detail in Japanese Patent No. 2801969, a PC-class computer is connected to ISDN as an ISDN terminal, and a 10-digit number unknown whether it is used as a fixed telephone number is called a called number. When a call setup message describing “unrestricted digital” is transmitted to the network, and the response from the network to the call is a disconnect message describing reason display number 3 (no route to the other party), it is described as a called number. The 10-digit number can be determined to be a number used as a fixed telephone number. At this time, the ringing bell of the called telephone is not ringed.

  The inventor of the present application uses a computer connected to ISDN and uses an 11-digit number known to be used as a mobile phone number or an 11-digit number known not to be used as a mobile phone number. An experiment was repeated in which a call setup message describing the unrestricted digital as the called number and the transmission capability was sent to the network, and the response to the call returned from the network was analyzed.

  The exchange between the ISDN terminal and the network is stipulated in detail in TTC standard JT-Q931 “ISDN user / network interface layer 3 specification”. In the case of the above-mentioned Japanese Patent No. 2801969, the ISDN and the analog telephone network Therefore, the network response to the call setup message is almost the same as that specified in the ISDN specification.

  However, the state of the network response to a call setup message in which the 11-digit number used as the mobile phone number is the called number and the transmission capability is “unrestricted digital” cannot be read from the ISDN specification. When designing a detailed specification of ISDN, a system that allows a mobile phone network to be connected to ISDN and that enables a call between an ISDN terminal and a mobile phone has not been specifically assumed.

  The inventor obtained the following knowledge as a result of the above-mentioned demonstration experiment. When a call setup message is sent from a computer connected to ISDN with the 11-digit number used as the mobile phone number as the called number and the transmission capability set to "unrestricted digital", a disconnect message is returned from the network. The calling process for the called number mobile phone does not proceed.

The inventor has also obtained the following knowledge. The disconnect message from the network includes descriptions of “reason display” and “generation source”. The 11-digit number used as the mobile phone number is the called number, and the transmission capability is “unrestricted digital”. In the case of a disconnect message for a call setup message, the description of “reason display” and “generation source” differs for each telecommunications carrier (carrier), and the called party number is set according to the “reason display” and “generation source” in the disconnect message. The carrier to which the mobile phone number belongs can be determined. Specifically, it is as follows.
● NTT DOCOMO reason display = 69, generation source = 3
● SOFTBANK MOBILE reason display = 69, generation source = 4
● KDDI reason display = 3, generation source = 3

  The inventor has also obtained the following knowledge. The above three types of “reason display” and “generation source” are described for a call setup message in which the 11-digit number that is not used as a mobile phone number is the called number and the transmission capability is “unrestricted digital”. A message different from the disconnected message is returned from the network. Therefore, in response to a call setup message in which an 11-digit number that is unknown whether it is used as a mobile phone number is a called number and the transmission capability is “unrestricted digital”, the above three types of “ When a disconnect message describing either “reason indication” or “generation source” is returned from the network, the 11-digit number is determined to be the number used as the mobile phone number in the corresponding carrier. Good.

  Furthermore, the inventor obtained the following knowledge. At the time of this application, for example, for the call setup message in which the 11-digit number used as the mobile phone number of NTT DOCOMO is the called number and the transmission capability is “unrestricted digital”, as described above, When a disconnect message of display = 69, generation source = 3 returns from the network, this may change in the future. Such cases were experienced in the process of the above demonstration experiment. When such a change actually occurs, it can be recognized immediately, and can be easily dealt with by adapting the subsequent criteria to the reaction information after the change.

=== The core of the invention ===
Based on the knowledge obtained from the above demonstration experiment, the inventor uses a computer connected to ISDN, sets the mobile phone number recorded in the survey target list as the called number, and sets the transmission capability to “unrestricted digital”. A call setup message is transmitted to ISDN, a disconnect message from the network for the call is received, and the carrier of the mobile phone number is specified based on the description contents of “reason indication” and “generation source” of the disconnect message The carrier identification information that can be recorded in association with the mobile phone number is periodically repeated, and the carrier identification information from the latest survey and the carrier identification information from the previous survey for a certain mobile phone number Determines whether they indicate the same carrier, and if they indicate different carriers, at least a new key. It has created information and the cellular phone number and the method of computing which performs a process of outputting associating identifying the rear.

It is the schematic of the computer system in an Example.

  An overview of a system for performing computing according to the present invention is shown in FIG. Here, a general personal computer 1 is used as the ISDN terminal. The computer 1 includes a CPU 2, a memory 3, a hard disk device 4, a display device 5, a keyboard 6, an ISDN communication board 7, and the like. The computer 1 is connected to the ISDN via an ISDN communication board 7 and a line connection unit (DSU) 8. It should be noted that the features of the present invention are not expressed in the illustrated configuration.

The hard disk device 4 stores an investigation target list. In the survey target list, a plurality of mobile phone numbers are described. Each mobile phone number records a history of survey results for each survey date. The survey results include the following information:
● Information specifying the type of message received from the network for the sent call setup message ● Description of “reason for disconnection” and “source” when receiving a disconnect message ● “reason for disconnection” and “source” Carrier identifier determined from the description of "

As already described in detail, the computer 1 operates in accordance with the program, and transmits a call setting message with the mobile phone number recorded in the survey target list as the called number and the transmission capability “unrestricted digital” to the ISDN. If the called number at this time is a number that is used as a mobile phone number, the network will send a disconnect message with the following “disconnection reason” and “generation source” description in one of the following three types: Come back from.
● NTT DOCOMO reason display = 69, generation source = 3
● SOFTBANK MOBILE reason display = 69, generation source = 4
● KDDI reason display = 3, generation source = 3

  In the system of this embodiment, a determination table in which a carrier identifier is associated with each of the above three types of “reason for disconnection” and “generation source” is provided, and the description content of the received disconnect message is compared with the determination table. The corresponding carrier identifier is specified, and the carrier identifier is recorded as the result of the search for the corresponding mobile phone number in the search target list. Since the carrier can be easily determined from the description contents of “reason for disconnection” and “generation source”, there can be an embodiment of computing in which this description itself is regarded as a carrier identifier.

  If there is a number that is no longer used as a mobile phone number in the investigation target list, the disconnection message from the network for the call setting message corresponding to that number will contain a “disconnection reason” and “generation source” other than the above three types. In this case, it may be determined that the number is no longer used, and a specific determination flag may be attached to the search result column for the corresponding mobile phone number, or this mobile phone number may be included in the survey target list. May be deleted, or may be processed by other appropriate methods.

  In this embodiment, when a disconnection message from the network for a call for a certain mobile phone number A is received, carrier determination is performed, and when the carrier identifier is entered in the investigation result column, the carrier identifier and the mobile phone number A In contrast to the carrier identifier in the previous survey result column, if the two are different, it is determined that the carrier has changed, and the mobile phone number A and at least the changed carrier identifier are associated with each other and output. .

  As a preferred embodiment, a mobile phone whose carrier before change and carrier after change are common, such as a list of mobile phone numbers changed from NTT Docomo to Softbank Mobile and a list of mobile phone numbers changed from SoftBank Mobile to KDDI. A list of telephone numbers may be created and output together with carrier identification information before and after the change.

  Furthermore, when a carrier change is detected for a certain mobile phone number, the event is recorded together with the detection time, the elapsed period is counted starting from the carrier change detection time for each mobile phone number, and the mobile phone is used with the carrier. By adopting a computing method that outputs information indicating the possibility of expiration of the carrier contract period together with the relevant number when a predetermined period related to the normal contract period of the contract has passed, more meaningful marketing information can be obtained. Can be obtained.

  In addition, by using a computer programmed to function as an IP phone terminal and analyzing the reaction from the IP phone network to the call, the 11-digit number that was called is the number used as each mobile phone number It is also possible to identify which carrier the mobile phone number belongs to.
