Description

  The present invention relates to a telephone service control system and a telephone service control method, and more particularly to a system and method for realizing a call connection service in a wired telephone network by connecting a wireless communication telephone to a wired telephone network. More specifically, the present invention relates to a telephone service control system and a telephone service control method for providing a high-function telephone connection service having a control function between a wireless communication telephone and a wired telephone network switch and a call connection control function between a plurality of telephone networks.

Wireless communication telephones such as mobile phones and PHSs (Personal Handyphone Systems) are within the reach of radio waves transmitted from base stations in the wireless communication telephone network, that is, within the calling area at any time and at any time. It is a device that enables a call. Wireless communication telephones have a high personal penetration rate because of their high portability, but there are also inconveniences such as inability to make calls in places where radio waves do not reach, and inability to make calls due to battery exhaustion. As one approach for solving such a problem, a mobile telephone that secures communication connectivity by connecting a wireless communication telephone to a wired telephone network is disclosed (for example, see Patent Document 1). In Patent Document 1, in a private branch exchange system, when a mobile phone runs out of batteries, it is connected to a wired line to receive power, and the location information of the mobile phone is registered via a wired telephone network.

  As described above, the wireless communication telephone has a high personal penetration rate, but it is difficult to say that the connectivity is high because of the coverage of the wireless base station. For this reason, as one of the measures for improving the connectivity of personally owned wireless communication telephones, a service model for connecting to a fixed telephone line that is already spread over a wide area can be considered. In fixed telephone lines, with the spread of wireless communication telephones, for example, the number of public telephones is decreasing, and the direction of degeneration is being followed. However, as part of these wired telephone networks, a telephone line interface such as a public telephone adapter is installed in place of the public telephone set so far, and a wireless communication telephone is connected to the telephone line interface, so that the wired telephone is connected. The ability to make calls over the network will ensure high call connectivity for wireless telephone owners and new revenues from fixed telephone service providers through the effective use of existing facilities and the provision of new services. Obtainable.

  The first problem in the construction of such a service model is that, from the viewpoint of utilizing existing equipment, a control method that eliminates the change to an existing device, particularly the terminal device, or keeps the change simple. Is to realize.

  In addition, when a wireless communication telephone is logically connected to a wired telephone network, it is assumed that the wired telephone network is a very wide area network and interconnected with many other telephone service provider networks. Therefore, the information necessary for the call connection, such as a telephone number, is enormous. Therefore, in a configuration in which a database is held in units of exchanges as in Patent Document 1, there is a possibility of being uneconomical and causing a reduction in processing capacity, and application to a wide area network is not realistic. In addition, the case where the wireless communication telephone is moved and connected to another exchange is not supported. Therefore, since the service model is a wide area network, it is a second problem to construct a realistic network model by efficiently deploying functions while utilizing existing facilities.

  Patent Document 2 described above describes, for example, that a modular plug of a mobile phone can be inserted into a modular jack so that wired communication can be performed in the same manner as a fixed phone. For example, it is not possible to charge the mobile phone and display the caller ID.

  In view of the above, the present invention provides a telephone service control system and a telephone in which an owner of a wireless communication telephone can receive provision of high-quality telephone service by connecting the owned wireless communication telephone to a wired telephone network.

  FIG. 5 is a diagram showing a sequence for registering the wireless communication telephone 10 in the wired switch 40 and the service control apparatus 110 when the wireless communication telephone 10 is connected to the connection cable 30. FIG. 7 shows a control flow of the wired switch 40 when the wireless communication telephone 10 is registered and accommodated in the wired switch 40 and a connection state between the connection cable 30 after the wireless communication telephone 10 is registered. FIG. 3 is a diagram showing a control flow of the wired switchboard 40 and a control flow until starting a calling process when the wireless communication telephone 10 makes a call. FIG. 8 is a diagram illustrating a control flow of the service control apparatus 110 when registering the wireless communication telephone 10 in the service control apparatus. Next, a procedure for registering the wireless communication telephone 10 in the wired switch 40 and the service control apparatus 110 will be described with reference to FIGS.

First, the wireless communication telephone 10 having a connection function with a wired telephone line is connected to the connection cable 30 (step S500).
Here, the wireless communication telephone having a function of connecting to a wired telephone line is, for example, a wireless communication telephone as described in Patent Document 2, and an appropriate one having a function connectable to a wired telephone line is used. it can. However, it is assumed that the wireless communication telephone 10 can store and execute a program for executing the wired telephone line connection procedure of FIG. 5 in advance. The connection cable 30 is a cable prepared exclusively for connecting a wireless communication telephone, and a modular cable having a modular plug that can be connected to a general wired telephone can be used as the cable itself. Further, as an example, the connection cable side may be provided with a function for connecting to a wired telephone line and a connection means with a wireless telephone, and the wireless telephone side may be provided with a simple means for connecting with the connection cable. .

  When the wireless communication telephone 10 detects that power is supplied from the wired switch by cable connection (procedure S501), the wireless communication telephone 10 enters a call (off-hook) state (procedure S502). In addition, the wireless communication telephone 10 prevents the wireless reception circuit from functioning. When the wired switchboard 40 detects a call (FIG. 7: step S700), it sends a dial tone sound (hereinafter referred to as DT sound) to the subscriber side (wireless communication telephone side) (steps S503 and S701). Also, a PB reception function (PBR) is activated to enable reception of push button sound (hereinafter referred to as PB sound) from the subscriber side (step S703). Even if the wireless communication telephone 10 receives the DT sound from the wired exchange 40 (step S503), it does not perform any processing. The radio communication telephone 10 notifies the code indicating the start of registration of the radio telephone number with a PB sound after entering the calling state (step S504). A predetermined code such as # 111 can be used as the code. The wired switchboard 40 converts the PB sound from the subscriber side into a number code using the PB reception function (step S703). Also, the DT sound to the subscriber side is stopped (procedures S505 and S704).

  Further, it is determined whether the number code received from the subscriber side is a telephone number (step S705). For example, if the first few digits of the number code start with 090, 03, it can be determined as a telephone number. If it is not a telephone number, a number code is identified (step S706). For example, the identification is performed based on whether the number code is a predetermined number indicating a number registration start notification. When it is identified as a number registration start notification, the process proceeds to a radio telephone number reception process and waits for the telephone number to be transmitted from the subscriber side. Following the number registration start notification, the wireless communication telephone 10 notifies the telephone number of the wireless communication telephone with a PB sound (step S506), and notifies the code indicating the end of registration of the wireless telephone number with a PB sound (step S507). . The telephone number of the wireless communication telephone device can be stored in advance in an appropriate memory. The wired switchboard 40 receives the telephone number by converting the number of the PB sound from the subscriber side by the PB reception function (step S707). Thereafter, when the wired switchboard 40 receives the number registration end notification code from the subscriber side (step S708), it returns the received telephone number to the subscriber side with a PB sound (steps S508 and S709). When the telephone number is returned as a PB sound, the radio communication telephone 10 converts the number by the PB reception function provided in the telephone and receives the telephone number (step S508). Thereafter, it is determined whether or not the received telephone number is coincident with its own telephone number, and if it is correct, a code indicating that the telephone number registration to the wired exchange 40 has been normally performed is notified with a PB sound (procedure S509), an on-hook state is set (procedure S510). Further, the wired exchange 40 starts the timer 52 at an appropriate timing (for example, after step S509). If the received telephone number does not match the own telephone number, the same processing as described above is repeated from the notification of the start of number registration.

  The wired switchboard 40 converts the PB sound from the subscriber side using the PB reception function, receives the normal notification of the number notification (steps S509 and S710), and further detects that the analog line has transitioned to the on-hook state (step 510). , S711), the wireless communication telephone accommodation table 50 provided in the wired exchange 40 has the accommodation of the wireless telephone accommodation flag of the table of the accommodation position to which the wireless telephone 10 is connected from no accommodation (for example, the flag from 0). In addition, the received wireless telephone number is registered corresponding to the accommodation position (step S712). Thereafter, the wired switchboard 40 sends a conversion table addition request to the service control device 110 (steps S511 and S713). The conversion table addition request includes information on the signal station code corresponding to the exchange device number of the wired exchange 40, the accommodation position, and the wireless telephone number. The signal station code can be stored in advance in an appropriate memory of the wired exchange 40. Instead of sending the signal station code and the accommodation position, a wired telephone number may be sent, or appropriate information for identifying the wired telephone number assigned to the line at the accommodation position may be sent. . When the service control apparatus 110 receives a conversion table addition request from the wired switchboard (step S800), the service control apparatus 110 searches the telephone number conversion table 120 provided in the service control apparatus 110 to determine whether or not the received wireless telephone number has been registered (step S800). Procedure S801). It is determined whether or not it has been registered (step S802). If it has not been registered, the received radio telephone number is newly registered in the conversion table. Further, the signal station code is determined from the received signal station code and the accommodation position. It is converted into a wired telephone number corresponding to the storage location and registered (step S803). For example, the service control apparatus 110 stores a wired telephone number in advance corresponding to the signal station code and the accommodation position, and can convert it to the wired telephone number by referring to this. If registered, the registered corresponding data in the telephone number conversion table 120 is deleted (step S805), and the wireless telephone number and the wired telephone number are registered from the data received in the same manner as in the above-described registration procedure S803. (Procedure S806). After registration is completed, the completion of addition of the telephone number conversion table is notified to the wired exchange 40 (steps S512 and S804), and the service control apparatus 110 ends the wireless telephone number registration process. The wired switchboard 40 receives the completion of the addition of the telephone number conversion table from the service control device 110 (steps S512 and S714), and ends the wireless communication telephone registration process.

  Here, the telephone number of the wireless communication telephone 10 transmitted and received between the wireless communication telephone 10 and the wired exchange 40 can be transmitted and received with a code number that is encrypted and converted for security. Further, the telephone number of the wireless communication telephone 10 transmitted from the wireless communication telephone 10 to the wired exchange 40 and the telephone number of the wireless communication telephone 10 transmitted from the wired exchange 40 to the wireless communication telephone 10 are for further security improvement. You may change the encryption method.

  FIG. 6 is a diagram showing a sequence for registering and deleting the wireless communication telephone 10 from the wired switch 40 and the service control apparatus after the wireless communication telephone 10 is detached from the connection cable 30. FIG. 9 is a diagram illustrating a control flow in which the wired switch 40 monitors the state of whether the wireless communication telephone 10 has been detached from the connection cable 30 and a control flow in which registration is deleted from the wired switch 40 when the wireless communication telephone 10 is detached. FIG. 10 is a diagram showing a control flow of the service control device 110 when the registration is deleted from the service control device after the wireless communication telephone 10 is detached from the connection cable 30. Next, a procedure for deleting registration of the wireless communication telephone 10 from the wired switch 40 and the service control apparatus 110 will be described with reference to FIGS. It is assumed that the radio communication telephone 10 stores a program for executing control for notifying the cable connection state of FIG.

  First, the wireless communication telephone 10 is connected to the connection cable 30 and periodically makes a call (off-hook) state when registration with the wired telephone 40 is completed (FIG. 6: step S600). A code indicating a connection state is notified with a PB sound (step S601), and the on-hook state is set (step S602). On the other hand, when the wired switchboard 40 detects a call (FIG. 7: step S700), it sends out a DT sound to the subscriber side (step S701), and a PB reception function for enabling reception of the PB sound from the subscriber side. Is activated (step S703). When the PB sound from the subscriber side is converted by the PB reception function (step S703), the wired switchboard 40 stops the DT sound to the subscriber side (step S704). Further, it is determined whether the number code received from the subscriber side is a telephone number (step S705). If the number code is not a telephone number, the number code is identified (step S706). If the connection state notification is identified, the timer provided for wireless communication telephone connection confirmation is cleared and reset (step S716). After that, it is detected that the state has shifted to the on-hook state (step S717), and the process of confirming whether the accommodated wireless communication telephone 10 is connected to the connection cable 30 is ended.

  Also, the wired switchboard 40 periodically reads the value of a timer provided for wireless communication telephone connection confirmation (FIG. 9: step S900), and determines whether the accommodated wireless communication telephone has been detached from the connection cable. It is determined whether or not it exceeds the timer value determined in advance as a reference (step S901). If the timer is not over, monitoring is continued without doing anything. When the timer over has occurred, the radio communication telephone accommodation flag of the accommodation position where the timer over has occurred is accommodated in the radio communication telephone accommodation table 50 provided in the wired switchboard 40 (for example, 1) to no accommodation (For example, 0) is changed (step S902). Thereafter, a conversion table deletion request is sent to the service control apparatus 110 (steps S603 and S903). The conversion table deletion request includes information on the radio telephone number.

  On the other hand, when the service control apparatus 110 receives a conversion table deletion request from the wired switchboard 10 (steps S603 and S1000), the service control apparatus 110 deletes the wireless telephone number data received from the telephone number conversion table 120 (step S1001). Thereafter, a conversion table deletion completion notification is transmitted to the wired exchange 40 (steps S1002 and S604), and the wireless communication telephone registration deletion processing is terminated. The wired switchboard 40 receives the conversion table deletion completion notification from the service control apparatus 110 (step S904), and ends the wireless communication telephone registration deletion processing.

FIG. 11 is a diagram showing a control flow of the calling process in the wired exchange 40 after the calling process is started (step S715) in FIG.
With reference to FIG. 11, FIG. 1, and FIG. 7, the procedure in the case of making a call from the wireless communication telephone 10 accommodated in the wired exchange 40 of FIG. 1 to the wired telephone 21 accommodated in the wired exchange 41 will be described.
Here, the wireless communication telephone 10 is a wireless communication telephone having a connection function with a wired telephone line, and has been registered in the wired switch 40 and the service control apparatus 110 by the above-described wireless communication telephone registration procedure. . For example, the wireless communication telephone 10 makes a call to the wired telephone 21 using a telephone directory function provided in the wireless communication telephone 10. Alternatively, the telephone number of the wired telephone 21 is directly transmitted by key input. On the other hand, when the wired switchboard 40 detects a call from the wireless telephone 10 (step S700), it sends a DT sound to the wireless telephone 10 (FIG. 7: step S701), and can receive the PB sound from the wired telephone 10. In order to do this, the PB reception function is activated (step S703). When receiving the PB sound from the wired telephone 10, the wired exchange 40 converts the number of the PB sound by the PB reception function (step S703), and stops the DT sound to the subscriber side (step S704). Further, it is determined whether the number code received from the subscriber side is a telephone number (step S705). If the number code is a telephone number, the calling procedure shown in FIG. 11 is activated (step S715).

  When the calling procedure is activated, the wired exchange 40 searches the wireless communication telephone accommodation table provided in the wired exchange 40 based on the accommodation location information of the caller (FIG. 11: step S1100), and the corresponding accommodation location table. The radio telephone accommodation flag is referred to, and based on the flag, it is determined whether the caller is a radio communication telephone (step S1101). For example, since the call originates from the accommodation position where the radio communication telephone 10 is accommodated, the radio telephone accommodation flag is accommodated. The wired switchboard 40 determines that the call originates from the wireless communication telephone, and replaces the caller telephone number with the wireless telephone number in the corresponding accommodation position table in the wireless telephone accommodation table (step S1102). Thereafter, the wired switchboard 40 checks the connection destination telephone number code received from the wireless communication telephone 10 (step S1103), and determines whether it is a wired telephone number or a wireless telephone number (step S1104). For example, the determination is made based on whether the head of the telephone number code is for a wireless telephone number such as 090 or 080. In outgoing calls to the wired telephone 21, it can be determined as a wired telephone number. In the procedure so far, the source telephone number is replaced with the wired telephone number assigned to the accommodating position where the wireless communication telephone 10 is accommodated, and the connected telephone number is the wired telephone number. A telephone call can be made by executing a predetermined calling procedure to the telephone (step S1105). In the number notification service, it is also possible to notify a wireless telephone number as a caller.

With reference to FIG. 12 and FIG. 1, the procedure in the case of making a call from the wireless communication telephone 12 accommodated in the wireless exchange 60 to the wireless communication telephone 10 accommodated in the wired exchange 40 will be described.

  The radio communication telephone 12 makes a call to the radio communication telephone 10 using a telephone directory function provided in the radio communication telephone 12. Alternatively, the telephone number of the wireless communication telephone 10 is directly transmitted by key input. On the other hand, the radio exchange 60 performs call detection from the radio communication telephone 12 (FIG. 12: step S1200) and reception of the connection destination telephone number (step S1201), and the received connection destination telephone number code is a wired telephone number. Or a wireless telephone number (steps S1202 and S1203). In making a call to the wireless communication telephone 10, the connection destination telephone number is a wireless communication telephone, and a predetermined calling procedure from the wireless communication telephone to the wireless communication telephone is performed (step S1205). However, since the wireless communication telephone 10 is connected to a wired telephone and the wireless function is stopped, it is not possible to make a call by a predetermined calling procedure. The radio exchange 60 determines whether or not the call connection could not be established by a predetermined call procedure (procedure S1206), and if the call connection cannot be established, notifies the service control device 110 of a conversion table search request (procedure S1207). The conversion table search request includes information on the wireless telephone number of the connection destination. The service control device 110 searches the telephone number conversion table from the received wireless telephone number to check whether the data is registered, and if the telephone number is registered or not, the wired telephone corresponding to the wireless telephone number. The number information is returned to the radio exchange 60. The radio exchange 60 receives the search result from the service control apparatus 110 (step S1208), and determines whether or not the telephone number is registered (step S1209). Since the wireless communication telephone 10 is accommodated in the wired exchange 40 and registered in the service control apparatus 110, the received search result is registered. When registered, the wireless switch 60 replaces the connection destination telephone number with the wired telephone number received from the service control apparatus 110 (step S1210). In the procedure so far, the source telephone number is the wireless telephone number, and the connection destination telephone number is replaced with the wired telephone number assigned to the accommodating position where the wireless communication telephone 10 is accommodated. A telephone call can be made by executing a predetermined calling procedure from the communication telephone to the wired telephone (step S1211).

  FIG. 13 is a diagram showing a control flow of processing for notifying the call control information to the service control apparatus when a call is made from the wireless communication telephone at the end of the call. With reference to FIG. 13, a procedure for notifying the service control device of call information of the wireless communication telephone 10 when a call is made from the wireless communication telephone 10 accommodated in the wired exchange 40 will be described.

  When the call is finished, the wired switchboard 40 activates the process shown in FIG. 13 and determines whether the call originates from the switchboard (step S1300).

On the other hand, in the case of a call originating from the local exchange, the wireless communication telephone accommodation table is searched from the accommodation position of the caller telephone (step S1301). It is determined whether or not (step S1302). For example, if the flag is 1 (accommodated), it can be determined that the call originates from a wireless communication telephone. If the call originates from the wireless communication telephone, a call history notification is transmitted to the service control apparatus (step S1303). The call history information includes information on the connection destination telephone number, the call start date and time, the call end date and time, and the radio telephone number of the location where the caller telephone is accommodated. On the other hand, when receiving the call history notification, service control apparatus 110 adds the received information to the wireless communication telephone call history database and stores it. Instead of notifying and storing the call start time and call end time, information for specifying the call time, other call time, and call charge may be notified and stored. Thereafter, a call history reception completion notification is transmitted to the wired exchange 40. The wired switchboard 40 receives the call history reception completion notification from the service control apparatus 110 (step S1304) and ends the process. If it is not a call from the wireless telephone in step S1302 (S1302: NO), a predetermined charging procedure in the wired network is performed (S1305).

  With this procedure, a call history when the call is transmitted from the wireless communication telephones 10 and 11 accommodated in the wired exchanges 40 and 41 is accumulated in the service control apparatus 110. Based on the accumulated call history, it is possible to charge the wireless communication telephone connected to the wired switchboard according to the agreement between the wired telephone service provider and the wireless telephone service provider.
