Abstract

PURPOSE:To transfer an incoming call to plural transfer destination telephone sets or to use plural messages for a caller on its purpose by devising the terminal equipment such that plural receptible subaddresses to one communication terminal equipment and the subaddress is used for a password. CONSTITUTION:When a subaddress is designated in a 'setup' message of an incoming call, a registered subaddress is collated with a received subaddress by a subaddress registration means 111 under the control of a subaddress collation means 114 and a function number is decided according to a function number decision means 115. When the call is set up, a message table is retrieved and a relevant message is outputted toward a caller. After the message is outputted to the caller, a transfer table is retrieved according to a transfer means 117 and a telephone number of a transfer destination described on the transfer table is dialed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multifunctional communication terminal device that connects to an I5DN user/network interface and has a voice message output and a telephone transfer isi.

[Prior Art] Some answering machines that can be connected to existing telephone networks have a function in which a caller selects and outputs a plurality of messages using a tone from a button. The answering machine can store a plurality of messages, and a password corresponding to each message is determined.

A caller places a call to an answering machine, and when the answering machine receives the call, it begins playing a normal answering message.

At this time, when the caller enters a predetermined several-digit number as a PIN using the button, the answering machine recognizes the tone of the button, matches the PIN, and displays the verification result. In response, a message is started to be played on the assumption that the user who knows the password will pause the message.

In addition, after recording the caller's message, such answering machines can forward the message to a pre-specified forwarding destination, and the forwarding destination's phone number is also a PIN code using the tone of the ash button. There are some things that can be specified by

[Intelligence M to be Solved by the Invention] However, in existing telephone networks, before a call is established, the caller's terminal I! Since the call cannot be controlled, it is necessary to enter the PIN number after the call is established in both cases of selecting a message and selecting a forwarding destination telephone number. Therefore, since the caller cannot input the telephone number and password of the other party consecutively, there is a problem that billing is performed even while inputting the password.

By the way, the Integrated Services Digital Network (ISDN: In
tegrated 5erveces Digital
Network), the interface that specifies the connection conditions at the boundary points when connecting terminals and networks is called the user-network interface, and is based on the international standard (CCI).
TT) as the 1.400 series, and is generally called the ■interface. TSDN
These services are VTMed using layer 3 (network layer) information, and this layer 3 information is generally called a message.

Call control is realized by exchanging messages such as call setup, response, and disconnection between the calling side, the network, and the called side.

In the following, messages that are used in normal terms, such as voice messages, will be simply referred to as voice messages, and layer 3 messages such as call setup, answering, and disconnection will be referred to as "call setup" messages, "answer" messages, and "disconnection" messages. It is written in brackets like ``''.

15DN has a caller ID notification function that allows the called party to know the caller's number. Using this function, it is possible to use different messages depending on the caller number. In other words, multiple recorded messages are registered in advance on the telephone, and when a call arrives, the telephone checks whether the caller number is the pre-registered caller number, and if it matches, plays the corresponding recorded message. It is something to do. Similarly, it is possible to register a plurality of forwarding destination telephone numbers and select the forwarding destination telephone number according to the caller number.

Using this feature will solve the above problem.

However, with this method, it is not possible to respond to calls made from public lines in either case of selecting a voice message or selecting a forwarding destination telephone number. Also, when multiple users use one caller number, the caller number cannot be used to uniquely identify the other party! ! There is a problem.

Therefore, the present invention allows the caller to enter a PIN number after the caller's phone number before establishing the call, and the receiver to verify the PIN before the call is established. Furthermore, by identifying the caller using that PIN, it is possible to use multiple voice messages depending on the caller, or to forward incoming calls to multiple forwarding destination phone numbers depending on the caller. The purpose of the present invention is to provide a communication terminal device that is possible.

[Means for Solving the Problems] In order to solve such problems, the first invention provides a sub-address registration means for registering a plurality of sub-addresses in correspondence with function numbers, and a sub-address registration means for registering a plurality of sub-addresses in correspondence with function numbers, and call setting information received at the time of an incoming call. a sub-address matching means for matching the included receiving sub-address with a registered sub-address registered in the sub-address registration means; A function number determining means searches for a function number corresponding to a sub-address, and control is performed by the function determined by the function number determining means.

A second invention is based on the first invention, and includes a message registration means for registering a message corresponding to a function number, and a message registration means for registering a message corresponding to the function number determined by the function number determination means. Message output means for outputting to the caller side.

A third invention is a transfer number registration means for registering a transfer telephone number in correspondence with a function number in the first invention, and a transfer registered by the transfer number registration means corresponding to the ll11 number determined by the function number determination means. and a transfer means for transferring an incoming call to a telephone number.

[Operation] In such a configuration, the 15DN numbering plan is standardized based on the telephone numbers of the existing telephone network according to the International Standards (CCITT), which uses subaddresses as passwords. The number regulations are determined at the user/network interface, and are the defining point between the user side and the network side. Therefore, on the terminal side, a number other than the 15DN number (corresponding to the telephone number in the existing telephone network) is used to identify the terminal or extension. Extension selection can be performed using the subaddress, which is number information.

15DN user/network interface allows multiple terminals to be connected, and by inputting a subaddress, it is possible to uniquely identify a terminal. 0 If the calling user specifies a subaddress, the network sends a message to the called side. The "call setup" message that is sent includes subaddress information.

When the terminal connected to the user/network interface on the called side receives the "call setup" message, it checks the subaddress to see if it matches the subaddress of its own terminal. If it is consistent, it will send a “call” to the network.
Sends either a ``call setup acceptance'' or ``answer'' message. If they do not match, either it is ignored or a ``release complete'' message is sent to the network that includes the information ``Reason: Terminal attribute mismatch.'' The subaddress can be up to 4 digits long and is entered in addition to the other party's phone number when making a call.

In the present invention, this subaddress is used as a password. In the user/network interface of l5DN, one type of sub-address is usually set for one terminal, but here, one type is assigned as a regular sub-address, and multiple sub-addresses are also set. Even when a ``call setup'' message is received, a ``response'' message is returned to the network.

Including the above, with the configuration described in the section of means for solving one problem, the caller side can input the subaddress consecutively after the phone number as a PIN number, and the subaddress is transferred from the network to the called party. included in the ``call setup'' message sent to the ``call setup'' message so that the PIN number can be verified before the call is established. As mentioned above, the subaddress can be set up to 40 digits, so
Needless to say, there is no problem with the accuracy of the PIN number.

Therefore, it is possible for the calling party to enter a PIN number before establishing a call, especially in sequence with the called number, and for the called party to be able to verify the PIN number before the call is established, A communication terminal that can use multiple voice messages depending on the caller, or transfer incoming calls to multiple forwarding destination phone numbers depending on the caller, by identifying the caller using a number. equipment can be provided.

Mode management means 118 is for managing whether the telephone is in home mode or absentee mode, and mode switching is performed using keyboard 106.

Table 1 Table 1 is a diagram showing an example of a sub-address table showing the correspondence between sub-addresses and function numbers registered and stored in the sub-address registration means 111.

Here, the subaddress in function number -0 ("40" in Table 1) means a regular subaddress defined by the user/network interface.

Regarding function number -0, the 0 function number and subaddress, which is positioned as a function for incoming calls from unspecified callers, are set using the keyboard 106.

Table 2 Table 2 shows the voice storage section 1 in which the function numbers and messages registered and stored in the message registration means 112 are stored.
05 is a diagram illustrating an example of a message table showing correspondence with an address of 05. FIG. Furthermore, if the message is not recorded by the user, the message flag is "0".
In this case, it is indicated that a fixed form message prepared in advance in the voice storage section 105 is to be used. On the other hand, when the message flag is "1", it indicates that a message recorded by the user is to be used. These settings are also performed using the keyboard 106.

Table 3 Table 3 is a diagram showing an example of a transfer table showing the correspondence between function numbers registered and stored in the transfer number registration means 113 and transfer telephone numbers. If the forwarding telephone number is set, the forwarding flag is set to "1", and if the forwarding telephone number is not set, the forwarding flag is set to Q".

These settings are also performed using the keyboard 106.

Next, the operation of the present invention upon receiving a call will be explained according to the flowchart shown in FIG. When the mode management means 118 sets the "at-home mode", if step 0 determines that there is an incoming call, step 1 determines the at-home mode, and as shown in step 2, the telephone functions as a normal telephone. below,
``I will explain the case where the absence mode J is set.

When a sub-address is specified in the incoming "call setting" message, the sub-address matching means 114 compares the registered sub-address registered in the sub-address registration means 111 with the received sub-address in step 4. If it is determined in step 5 that the sub-addresses match, the function number determining means 115 searches the sub-address table as shown in Table 1 for the corresponding function number as shown in step 6 and determines the function number. If it is determined in step 3 that the call is not a subaddress designated call, the function number is determined to be "0" as shown in step 7.

After determining the function number, send a "response" message to the rope as shown in step 8. If a "response confirmation" message is received from the network in step 9, the call has been established, and the message table is searched in step 10. If the message flag is 1'' in step 11, the message output means 116 Step 1 is performed according to the function number determined according to the address of the voice storage unit 105 recorded in the message table as shown in Table 2.
As shown in 2, a corresponding message is output to the caller.

If the message flag is 0'' in step 11, a fixed message message or message is output as shown in step 13.In step 9, if a ``response confirmation'' message is not received and a ``release'' message is received from the network. If so, call release processing is performed as shown in step 14. After outputting the recorded message to the caller, the transfer means 117 searches the transfer table as shown in Table 3 using the function number determined as shown in step 15, and in step 16, it is determined that the transfer flag is "1". If so, call the forwarding destination phone number listed in the forwarding table as shown in step 17, and if a "response" message is received from the network in step 18, call back the two B channels as shown in step 19. Perform phone forwarding for use with.

In step 18, if a "response" message is not received from the network due to reasons such as the other party is busy, but instead a "release" message is received, a fixed form message to the effect of failure is output to the caller as shown in step 2o. , step 21
Call release processing is performed as shown in .

It should be noted that the present invention is not limited to the above-described embodiments; it goes without saying that the present invention can be applied not only to telephones but also to various terminal devices such as facsimile machines, as long as they can be connected to the user/network interface of I5DN.

[Effects of the Invention] As explained above, the present invention enables one communication terminal device to set a plurality of sub-addresses that can receive data, and allows the sub-addresses to be used as a password. By associating messages, voice messages, and forwarding phone numbers, it is possible for the caller to enter the PIN number consecutively with the called number before establishing a call, and the called party's communication terminal device can enter the PIN number before establishing the call. By verifying the PIN number before establishing a call, and further identifying the caller using the PIN number, you can use multiple voice messages depending on the caller, and multiple forwarding destinations depending on the caller. It has the effect of being able to forward incoming calls to a telephone number.
