Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an access control system in an incoming call connection control system for controlling access for changing a telephone number of a transfer destination for transferring an incoming call to a telephone of a transfer telephone contractor. .

[0002]

2. Description of the Related Art Transfer telephone service is a service for transferring an incoming call to the telephone of the contractor of the transfer telephone to the telephone of the transfer destination telephone number registered by the contractor. Or when you are out of the office for reasons such as closing a store at night, or when you cannot answer the phone due to important work, you can use the telephone number that has been specified in advance for the incoming call to the contractor. By transferring to a telephone, an important telephone can be properly received, which is a very useful telephone service.

In the transfer telephone service, the transferee telephone number when a transfer telephone contractor transfers an incoming call is not always the same, and is often changed. For example, if you are the owner of a store, after closing the store, you usually forward incoming calls to your home, but in some cases you may forward them to your car phone, your home, or even run your own business. Change the transfer destination phone number so that you can transfer to another store.

The change of the telephone number of the transfer destination is usually performed from the telephone of the contractor of the transfer telephone, but is not necessarily performed from the telephone of the contractor, and in some cases, from a public telephone while moving. There are many cases where it is desired to make a call from a telephone other than the subscriber's telephone, such as.

A so-called remote control function for changing the transfer destination telephone number from a telephone other than the contractor's telephone has not been provided as a function of an exchange in the past. In order to perform the call, conventionally, a remote control device is separately connected to the telephone of the transfer telephone contractor, that is, the telephone line of the contractor, and a general incoming call is performed from the other telephone to the remote control device, and then an in-channel signal is transmitted. The remote control data for changing the transfer destination telephone number is transferred to the remote control device.

When the remote control device receives the remote control data for changing the transfer destination telephone number, the remote control device autonomously makes a call and sets the transfer destination by the customer control procedure from the telephone of the subscriber of the normal transfer telephone. We are in the process of changing the phone number.

When the transfer telephone contractor's telephone is a pink telephone, if the user and the transfer telephone contractor cannot be distinguished from each other and erroneous control or mischief is a concern, customer control is performed at the terminal. It is necessary to set the number to be restricted and release the restriction each time customer control is required.

[0008]

As described above, the conventional transfer telephone does not have a so-called remote control function for changing the transfer destination telephone number from a telephone other than the subscriber's telephone. When it is desired to change the transfer destination telephone number from the telephone, it is necessary to separately connect a remote control device to the subscriber's telephone line, which is very uneconomical.

Further, in the conventional transfer telephone, in order to change the telephone number of the transfer destination from a telephone other than the telephone of the contractor, the remote control device is connected to the telephone of the contractor of the transfer telephone, and the remote controller is connected. A general incoming call is made from the other telephone to the remote control device, the remote control data for changing the transfer destination telephone number is transferred, and the remote control device automatically calls the remote control device to transfer the transfer destination telephone number. Even when changing the password, it is possible to control the password information by the terminal function regarding the remote control processing. However, since the transfer destination telephone number is changed according to the transferred information in such processing, the transfer destination telephone number is changed. The number can be freely set. Therefore, for example, it becomes possible for hackers and others to register the telephone number of the remote place to which they want to connect, and for example, it becomes possible to make illegal calls such as making a call to a remote place such as a long distance call at the local call charge. There is a problem of becoming.

Further, when the telephone of the transfer telephone contractor is a pink telephone, conventionally, it is necessary to set the customer control processing to be restricted, and to release the restriction when the customer control processing is required. Therefore, it is necessary to set and release the regulation number one by one,
There is a problem in that the operation becomes complicated and, if this operation is neglected, mischief or unauthorized use becomes possible as in the case of the remote control processing described above.

The present invention has been made in view of the above,
The purpose of this is to limit the free and easy change of the transfer destination telephone number from a telephone other than the telephone of the transfer telephone contractor to prevent unauthorized use of the transfer telephone, and to control access to the incoming call using the connection control method. To provide a method.

[0012]

In order to achieve the above object, the access control system in the connection control system for incoming calls according to the present invention comprises a calling side exchange which receives an outgoing call and a receiving side exchange which accommodates a called party. A method for connecting an incoming call based on connection control data provided in a called exchange in a communication network in which a common line signaling network is used to transmit and receive control information between exchanges via a signal relay exchange in the common signaling network In the connection control method of the incoming call for controlling the call, a control for requesting to the called side exchange including the first identification information input from the terminal accommodated in the called side exchange, which is activated by a predetermined dial operation. A control unit that creates information, sets the identification code of the signaling repeater exchange in the control information to create transfer information, and a transmitter / receiver that sends and receives the transfer information to and from a predetermined signal relay exchange. And a connection control data indicating a method of connecting an incoming call to a called party, and a first identification unit for identifying an accessor who accesses the connection control data via the remote control transmission unit. 2 identification information, input error count data of the identification information, and security data including lock status data for setting whether or not to prohibit access to the connection control data. Further, the receiving side exchange has the transmission / reception unit. The first identification information is the second
From a control unit for requesting update information of transfer related data to the remote control transmission unit when the matching result matches the identification unit of the identification information, and an updating unit for receiving the update information and updating the transfer related data. When the remote control receiving unit is activated from the remote control transmitting unit and the connection control data is updated, if the matching results in the matching unit do not match, the input error frequency data is counted up and forced. The connection control for disconnection is performed, and when the input error count data exceeds a predetermined count, the lock status data is changed to a lock status, and the lock status data is referred to at the next access to the connection control data. The gist is to perform connection control that denies access to the connection control data when the lock state is set.

Further, the access control system in the connection control system for incoming calls according to the present invention is an incoming call for controlling access for changing a telephone number of a forwarding destination for forwarding an incoming call to a telephone of a transfer telephone contractor. And a transfer-destination telephone number storage unit for storing a transfer-destination telephone number which is accessed only from the telephone of the contractor and whose setting is changed by an operation from the telephone of the contractor. From designated telephone number storage means for storing designated information for designating the actual telephone number of the transfer destination among the transfer destination telephone numbers stored in the transfer destination telephone number storage means, and a telephone other than the subscriber's telephone Personal identification information storage means for storing personal identification information for accessing the designated telephone number storage means for changing the designated information stored in the designated telephone number storage means; The personal identification information input from the other telephone is stored in the personal identification information storage means as authentication information for enabling the other telephone to access the designated telephone number storage means and change the designated information. If the collating means for collating with the existing personal identification information and both the personal identification information as a result of collation by the collating means, the other telephone accesses the designated telephone number storage means, and the operation is performed from the other telephone, The gist is to have a change control means for controlling the designated information stored in the designated telephone number storage means so that the designated information can be changed.

Further, in the access control method in the incoming call connection control method of the present invention, if the result of the collation by the collating means is that the two pieces of password information do not coincide with each other, the number of times of non-coincidence is counted, and the number of times of non-coincidence is counted. When the number of disagreements counted by the disagreement number counting means reaches a predetermined number, a lock state setting means for setting a lock state for prohibiting change of the designated information from the other telephone is further provided. .

[0015]

In the access control method of the incoming call connection control method of the present invention, when the remote control transmitter activates the remote control receiver to update the connection control data, if the collation result in the collating section does not match, the input is performed. The error count data is counted up to perform connection control for forced disconnection.If the input error count data exceeds a predetermined number, a lock state is set, and the lock state is set the next time the connection control data is accessed. Access to the connection control data is denied.

Further, in the access control method in the incoming call connection control method of the present invention, the personal identification information input by a telephone other than the telephone of the contractor is collated with the personal identification information stored in the personal identification information storage means, When the two pieces of password information match, the designated information can be changed by an operation from the other telephone, and one of a plurality of transfer destination telephone numbers is designated by this designated information.

Further, in the access control system in the connection control system for incoming calls according to the present invention, when the two pieces of password information do not match, the number of mismatches is counted, and when the number of mismatches reaches a predetermined number, another It is prohibited to change the specified information from the telephone.
