DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having a function of notifying a called terminal of a called number and connected to a communication network such as an ISDN network.

[0002]

2. Description of the Related Art In recent years, telephones having an answering machine function have been widely used. Here, the answering machine function of the conventional telephone automatically responds to an incoming call generated while the answering machine mode is set, sends out a preset voice message, and records the incoming voice. Therefore, whether to activate the answering machine function is determined by whether to set the answering machine mode. Also, the type of voice message to be sent is determined.

[0003]

As described above, in the conventional telephone, whether or not to activate the answering machine function is determined by whether or not to set the answering machine mode. For example, it is inconvenient to make a ringing tone and wait for the user to go off-hook, and respond when the user goes off-hook. That is, for example, there is a case where the answering machine mode is set in order to prevent a prank call at night, but in this state,
Phone calls from family members and emergency calls are also handled by the answering machine.

[0004] Further, since only one type of voice message is transmitted, it is inconvenient. That is, for example, when one telephone is shared between a store and a home, registering a voice message for a store cannot respond to a call for home use, and registering a voice message for a home causes a call to the store. Cannot respond to outgoing calls. In such a case, you have to register either voice message,
Not the best message.

The present invention has been made in view of such circumstances, and it is an object of the present invention to use a mixture of a normal incoming call operation and an incoming call operation using an answering machine function. An object of the present invention is to provide a highly convenient telephone that can be used.

[0006]

According to a first aspect of the present invention, there is provided a mobile communication system in which predetermined information indicating whether to activate the answering machine function in association with each of a plurality of incoming numbers including those having different subscriber numbers. Is stored in the storage means. Then, it is determined based on information stored in the storage means whether to activate the answering machine according to the incoming call number notified from the communication network in response to the incoming call, and if the answering machine function should be activated, the answering machine function is activated. Upon activation, a preset message is transmitted, and otherwise, the calling means is activated to generate a ringing tone. In the second invention, predetermined information indicating the type of message to be transmitted by the answering machine function in association with each of a plurality of called numbers including those having different subscriber numbers is stored in a storage means. deep. Then, a message is selected from a plurality of types of messages based on the information stored in the storage means in accordance with the incoming call number notified from the communication network in response to the incoming call, and the selected answering message is transmitted to the answering machine function. I did it.

[0007]

By taking such means, for example, for each of a plurality of subscriber numbers or for each of a plurality of subaddresses, a message to be activated by either the answering machine function or the calling means or to be transmitted by the answering machine function In accordance with the incoming call number notified from the communication network in response to an incoming call, either the answering machine function or the calling means is activated, or the message sent by the answering machine function is appropriately switched. . Therefore, one telephone can be used like a plurality of telephones. Moreover, it is possible to switch whether to activate the answering machine function or the calling means, or to switch the message sent by the answering machine function according to the subscriber number in the called number. It is also possible to use the answering machine function properly even for an incoming call from a terminal that is dedicated to and does not have a subaddress designation function.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a functional block diagram showing the configuration of the telephone according to the present embodiment. In the figure, reference numeral 1 denotes a control unit for generally controlling the telephone. 2 is an ISDN line interface for interfacing with the ISDN network;
The layer 1 protocol (matching electrical and physical conditions), the layer 2 protocol (link setting control, error control), and the layer 3 protocol (call control) in N are executed under the control of the control unit 1. I do.

An audio signal processing unit 3 includes a codec and the like. The audio signal processing unit 3 reproduces an audio signal from the received audio data supplied from the ISDN line interface 2 and supplies the reproduced audio signal to a receiver 4 a of the handset 4. The voice signal output from the transmitter 4b is converted to voice data via the ISDN line interface 2 as voice data.
Output to N network.

Further, an operation panel 5 and an absence registration table 6 are connected to the control unit 1, respectively. Here, the operation panel 5 includes, for example, a liquid crystal display (LCD) for the user to input an instruction to the control unit 1 and a key operation unit 5a for the control unit 1 to display various information to the user. And a display unit 5b. The absence registration table 6 is, for example, a RAM, and registers whether or not to activate the answering machine function and the type of message to be transmitted in association with the incoming call number.

Reference numerals 7 and 8 denote message memories for storing voice messages to be sent out at the time of answering machine response, each of which can store one type of message. These message memories 7 and 8 are provided with changeover switches 9 and 10
Is selectively connected to the audio signal processing unit 3 to store the audio data given from the audio signal processing unit 3 under the control of the control unit 1 or to store the stored audio data in the audio signal processing unit 3. Or output to. Reference numeral 11 denotes a recording device for recording the voice arriving at the time of answering machine response.

The control unit 1 has, for example, a microcomputer as a main control circuit. In addition to the well-known control means of the telephone, a well-known answering machine function 1a is provided.
And answering machine control means 1b. The answering machine control means 1b refers to the absence registration table 6 based on the incoming call number notified from the ISDN network at the time of receiving a call, and
a, and determines the type of voice message to be sent.

FIG. 2 is a diagram schematically showing a memory map of the absence registration table 6. As shown in FIG. First, this phone has multiple IS
A DN address (ISDN number + subaddress) is set, and these are stored in the absence registration table 6 in the term of called number. An area for registering absence registration information and a message number is set in association with these numbers. Here, the absence registration information is information indicating whether or not to respond to an answering machine. In the present embodiment, if "absence" is designated, it indicates that an answering machine response is performed.
The message number is the number of the message sent at the time of answering machine response. In this embodiment, the message memory 7
The voice message registered in the message memory 8 is "1", and the voice message registered in the message memory 8 is "2".
The setting of these information can be arbitrarily changed by an instruction operation on the key operation unit 5a.

Next, the operation of the telephone configured as described above will be described according to the processing procedure of the control unit 1. First, in the standby state, the control unit 1 monitors the occurrence of a call and an incoming call in steps a and b as shown in FIG. Here, when a predetermined calling operation such as the handset 4 being off-hook is performed, the control unit 1 shifts the processing from step a to step c, and in step c, the calling processing is performed according to a well-known general procedure. Do.

On the other hand, when an incoming call occurs in the standby state and this is notified from the ISDN line interface 2, the control section 1 shifts the processing from step b to step d.
In step d, the control unit 1 takes in the called number notified from the ISDN. Subsequently, in step e, the control unit 1 searches the absence registration table 6 for the incoming call number captured in step d, and reads the corresponding absence registration information and message number. Subsequently, in step f, based on the absence registration information read in step e, the control unit 1 determines whether or not absence registration has been performed for the called number of the current incoming call.

Here, for example, if the called number is "881111"
If the number is "-000", "absence" is not set in this number as shown in FIG. 2, so the control unit 1 shifts the processing from step f to step g and performs a normal incoming call processing. . The normal incoming call process is a process of, for example, generating a ringing tone, waiting for an off-hook, and responding with the off-hook.

For example, if the incoming call number is "881111-
If it is "001", "absence" is set in this number as shown in FIG. 2, so that the control unit 1 shifts the processing from step f to step h. In step h, the control unit 1 determines whether the message number read in step e is "1" or "2".
If it is "1", the changeover switches 9, 1 in step i
After switching 0 to the message memory 7, the process proceeds to step k. If "2", the changeover switches 9 and 10 are switched to the message memory 8 in step j, and then the process proceeds to step k. Then, in step k, the control unit 1 performs a well-known answering machine response process using the answering machine function 1a. That is, for example, after a link is set, the voice message stored in the one selected by the changeover switches 9 and 10 of the message memories 7 and 8 is given to the voice signal processing unit 3, and this is sent to the ISDN line interface. 2 to the ISDN network. Further, the voice arriving during a predetermined period thereafter is recorded by the recording device 11.

Thus, according to this embodiment, whether to activate the answering machine function and the type of voice message to be transmitted can be switched according to the incoming call number, so that a plurality of telephones are virtually installed. Can work. By the way, the subaddress in the ISDN address is notified to the called side only when specified by the calling side. If the calling side does not specify the subaddress, the subaddress is notified.
As the SDN address, only the ISDN number, which is a subscriber number managed by the network side, is notified. If the called number notified in this way is only the ISDN number, it can be considered that this is equivalent to the sub-address being “000”. In the present embodiment, the notified called number is “ 881111 ", then" 881111-00
"0" and the notified incoming number is "881"
If it is "112", the answering machine function can be properly used based on the setting relating to "881112-000". As a result, according to the present embodiment, the caller side
Even in the case of an STN (Public Switched Telephone Network) terminal or the like where it is impossible to specify a subaddress, it is possible to properly use the answering machine function by properly using the ISDN number on the caller side. .

That is, if different ISDN addresses are set for the store and the home, respectively, when the store closes, the answering machine responds to an incoming call with the store ISDN address, and the home ISDN. For an incoming call at an address, a usage method such as performing a normal incoming call operation can be adopted. In addition, by registering voice messages for shops and homes, IS
A message for a store can be sent for an incoming call with a DN address, and a home message can be sent for an incoming call with a home ISDN address, and the most appropriate message can be transmitted to the caller. Can be. In this way, it can be used as if two telephones for a store and a home were installed.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, both the "function of switching whether or not to answer a message" and the function of switching a voice message are provided, but only one of them may be provided. In the above embodiment, the telephone is connected to the ISDN network. However, the present invention can be applied to any telephone connected to a network having a function of notifying a called terminal of a called number.

In the above embodiment, two message memories are provided and two types of voice messages can be registered. However, three or more voice messages may be registered. In addition, various modifications can be made without departing from the spirit of the present invention.

[0022]

According to the present invention, for example, for each of a plurality of subscriber numbers or for each of a plurality of subaddresses, which of the answering machine function and the calling means is activated, or the type of message sent by the answering machine function Based on the setting, according to the incoming call number notified from the communication network in response to an incoming call, whether to activate the answering machine function or the calling means, or to appropriately switch the message sent by the answering machine function, Normal incoming call operation and incoming call operation using answering machine function can be used together,
In addition, a highly convenient telephone that can use the answering machine function properly even when an incoming call is generated by making a call by designating only the subscriber number.
