DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital cordless telephone terminal having an answering machine function.

[0002]

2. Description of the Related Art PHS (Personal Handy Phone System) and PDC (Personal Digital Cellular) are typical digital cordless telephone terminals.
It has been known. A PHS terminal, which is an example of a digital cordless telephone terminal currently used, is sometimes called a PHS mobile station. This PHS mobile station has an ISDN (Integrated Services) as shown in FIG.
By transmitting and receiving radio waves to and from a base station connected to a telecommunications line facility such as Digital Network, telephone or data communication can be easily performed even outdoors. At first, there was little need for an answering machine in cordless telephone terminals due to the portability of PHS mobile stations, and there were few terminals equipped with an answering machine function, but in recent years, cordless telephones have been used for reasons such as diversification of terminal users' lives. The answering machine function has become an essential function in terminals.

[0003] The answering machine function of a digital cordless telephone terminal cannot leave much data like a telephone connected to a general line because of its portability, and can leave only a few data at most. Moreover,-
The amount of data is also small.

Next, a conventional PHS mobile station will be described with reference to FIG. When an incoming call is transmitted through the radio unit B6, the user of the PHS mobile station is notified that there is an incoming call by means of ringing of the ringer B4 or vibration of a vibrator. The LCD (liquid crystal display) B3 also indicates that there is an incoming call. Terminal user operates key operation section B
When the call key of No. 9 is pressed, the state shifts to a call state, and a call is made through the handset B5. If the PHS mobile station user does not answer the phone even though there is an incoming call, answering machine recordability determination means b
4 determines whether or not a recording area still remains, and if there is a recording area, the answering machine function control section B2 activates the answering machine function section B10 to record data. The data is recorded in the data recording section in the answering machine function section B10. PHS
The mobile station user later restarts the answering machine function by pressing the play key of the key operation unit B9 to play back the data.
The fact that there is no data recording area is notified to the sender.

[0005]

As described above, as described above, PH
In a digital cordless telephone terminal such as an S mobile station, a large number of data recording areas cannot be secured due to its portability, and thus only a few data can be recorded. Also less. Therefore, for example, if the number of recordable data is three, data of the fourth or more data cannot be recorded, so that data cannot be transmitted to the terminal user. Therefore, the following problems occur.

In a state where the terminal user is waiting for a call with high importance, and when the terminal user cannot answer the call due to a situation, the answering machine is set. However, if another phone calls before the high-priority telephone and records the data, the high-priority telephone cannot record the data. As means to solve this situation,
Japanese Patent Application Laid-Open No. 78047 discloses a technique of a portable terminal capable of setting a recording limit time according to the priority of a calling number.

However, according to this prior art, it is possible to cope with a system which can be used to record any number of records within a certain period of time currently used for a telephone connected to a general line, but it is often used for a PHS mobile station. It cannot deal with systems that have a limited maximum number of records.

Japanese Patent Application Laid-Open No. 7-95281 discloses a technique in which a password is used to overwrite low-priority password data with high-priority data according to its priority. If
It is necessary to inform the sender of the password in advance, and there is a disadvantage that it is difficult for the terminal user to freely change the priority of the password.

Further, in the conventional portable terminal, after the recorded data is reproduced, the terminal user has to delete the data, so that the user may forget to delete the data. Therefore, new incoming data is not recorded. Things happened.

Accordingly, the present invention provides an easy-to-use digital cordless telephone terminal with an answering machine function that covers a small number of answering machine recording areas of the cordless telephone terminal.

Another object of the present invention is to provide a digital cordless telephone terminal with an answering machine function in which data from a specific person, that is, data of a telephone having high importance, is always recorded even if the recording area is lost.

Another object of the present invention is to provide a digital cordless telephone terminal with an answering machine function having a function of preventing unnecessary data that has been reproduced from being forgotten to be erased.

The answering machine function control unit A2 has a data reproduction judging unit a5 and an answering machine storage availability judging unit a4.

In the digital cordless telephone terminal according to the present embodiment, (1) a function of recording data from a caller who wants to receive data even if there is no recording area in the answering machine function, and (2) an answering machine function (3) a function of displaying the telephone number of the erased caller even if the data recorded in step (3) is deleted, (3) a function of automatically deleting data recorded by the answering machine function after a lapse of a fixed time, (4) A function that can set a certain time according to the caller's priority. (5) Judge whether data recorded by the answering machine function has been reproduced, and if it has been reproduced, the data can be deleted after a certain time elapses (6) a function that can set the certain time according to the priority of the caller.

Hereinafter, the functions of the digital cordless telephone terminal according to the present embodiment will be described.

The functions (1) and (2) will be described with reference to the flowchart of FIG. 2. (C1) When an incoming call is transmitted to the control unit A1 through the radio unit A6 while answering machine is waiting (C1), (C2) In A1, while recognizing the telephone number of the caller through the calling number recognizing means al, an incoming call to the digital cordless telephone terminal user (hereinafter referred to as a terminal user) is made by ringing the ringer A4 or vibrating the vibrator. Notify that there was. In response to this, the terminal user operates the key operation unit A
When the control unit A1 is given a response to the incoming call by pressing the call key of No. 9 or the like (C3), the control unit A1 uses the handset A5 to communicate between the other party and the terminal user. Is performed (C4).

However, if the answering machine is waiting for answering machine setting (C1), there is an incoming call (C2), and if the terminal user does not respond to the incoming call (C3), the control unit A1 waits for a certain period of time (C3). C5) causes the answering machine function control unit A2 to control and execute the answering machine function (C5).
6). The answering machine function control section A2 determines whether or not a data recording area remains in the data recording section of the answering machine function section A10 through the answering machine storage availability judgment means a4 (C7). If it is determined that the data recording area remains and data recording is possible, the answering machine function control unit A
In No. 2, the answering machine function unit A10 is operated to cause the data recording unit to record the transmitted data, and at the same time, the calling party number of the sender of the data and its priority are stored in the calling party number storage device A11. (C8).

On the other hand, if it is determined that there is no data recording area and data cannot be recorded, the control unit A1 stores the telephone number of the caller who perceived the incoming call in advance in the calling number / priority order registration. The calling number priority order searching means a2 checks whether or not the caller is registered in the device A7. The telephone number of the caller relating to the incoming call is included in the telephone numbers of the registered callers. Let them determine priorities. The priority of the telephone number thus determined and the priority of the telephone number of the already recorded data are compared by the calling number priority comparing means a3. If the determined priority is lower, the priority is determined. And the telephone number of the discarded caller is displayed on the liquid crystal display A3 (C10). If the priority of the determined telephone number is high, the data of the priority determined from the data of the lowest priority among the data of each priority already recorded is overwritten and recorded (C11).
The term "overwrite" in this specification is a broad concept including recording directly on existing data, or recording new data in an empty area by deleting old data.

As a result, the above functions (1) and (2) can be executed, and even if the data recording area is exhausted, if the originator of the incoming call is the other party who wants to receive data, the priority order is set. By setting it high, the data can be reliably recorded in the recording area and left, and when the recorded data of another caller is deleted, the telephone number of the other caller can be displayed. Even if the data of other callers is deleted, the terminal user can know who the caller is from the displayed telephone number from the display of the deleted caller's telephone number.

Next, the functions (3) and (4) will be described with reference to the flowchart of FIG. 3. When data from the caller concerning the incoming call is being recorded in the recording area (D1), the communication is terminated and disconnected. Or (D2), if the recordable time elapses even if the communication is not terminated (D3), the recording of the data is terminated and the answering machine function is stopped (D4).
The state shifts to the answering machine setting standby state. At this time, the control unit A1 starts the timer A8 (D5). When the fixed time set by the timer A8 elapses and the timer expires (D6), the data is erased (D7).
Thus, the terminal user can set the time from data recording to erasure. In this case, when the terminal user assigns priorities to the set time of the timer A8 in advance according to the caller, when the data of the caller relating to the incoming call is recorded by the above-described procedure, the control unit A1 sets the timer A8 The answering machine function control unit A2 can start the answering machine function unit A10 to erase the data when the time set in advance by the terminal user according to the priority order elapses. In this way, the above functions (3) and (4) can be executed, and it is possible to prevent forgetting to delete the data recorded by the answering machine function, thereby preventing the recording area of the data from the next sender from being lost. The setting time of the timer A8 is longer for high priority and important data, and the setting time is shorter for low priority data, so that the terminal user can select data according to the caller. Become.

Next, the functions (5) and (6) will be described with reference to the flowchart of FIG. 4. Whether the communication is terminated during the recording of the data from the sender regarding the incoming call in the recording area (E1) (E2) If the recordable time elapses even if the communication is not completed (E3), the data recording is terminated and the answering machine function is stopped (E4), and a transition to the answering machine setting standby state is newly made. At this time, the control unit A1 does not start the timer A8 immediately, and makes the data reproduction determination unit a5 determine whether the data has been reproduced once. When it is confirmed that the data has been reproduced (E
5), the control section A1 starts the timer A8 (E6).
Then, after the timer A8 is started, when the fixed time has elapsed and the timer expires (E7), the control unit A1 starts the answering machine function unit A10 via the answering machine function control unit A2 to erase the data ( E8). Thus, the time from data recording to erasing can be set by the terminal user.

Here, the set time of the timer A8 can be set in advance by the terminal user according to the priority of the telephone number. Thus, the above functions (3) and (4) can be executed, and data can be prevented from being erased before reproduction. The setting time of the timer A8 can be increased for high priority and important data, and the setting time can be shortened for low priority data, so that the terminal user can select data according to the caller.

[0029]

As described above, according to the present invention, the following effects can be obtained.

According to the first aspect of the present invention, there is provided a judging means for judging whether or not a recording area for recording data from a caller remains, and a telephone number of the caller and a priority of the telephone number are registered in advance. When the determination unit determines that there is no recording area for the data at the time of the incoming call, if the caller relating to the incoming call has a higher priority than other callers with reference to the registration unit Since the data from the caller relating to the incoming call is overwritten on the recording area of the data of the other caller, the data is recorded in the empty recording area, so that even if the data recording area is exhausted, the incoming call is not affected. If the caller is the other party who wants to receive the data, raising the priority will ensure that the data can be recorded and recorded in the recording area. Even if I lost the data recording area due to reasons such as it has been recorded, if the priority of the telephone number of the person you want to receive the data to the highest value, so that the data can be left always a. As a result, data with high importance is always recorded and can be transmitted to the terminal user, so that it is released from a situation where important data is not recorded and cannot be transmitted to the terminal user.

According to the second aspect of the present invention, when the record data of the other caller is deleted, the telephone number of the other caller can be displayed, so that the data is deleted even if the data is deleted. The displayed telephone number of the caller is displayed, so that the terminal user can know who the caller is from the displayed telephone number, and the data is erased as the terminal user. From the displayed phone number, it is possible to know from whom the call originated, and it is possible to take measures such as calling back later. This frees the user from not knowing who has transmitted the erased data.

According to the third aspect of the present invention, the data recorded by the answering machine function can be automatically erased after a certain period of time, so that the data recorded by the answering machine function can be prevented from being forgotten to be erased. This prevents the recording area of the data from the sender from being lost. As a result, the terminal user is freed from the trouble of erasing data after data reproduction, and is also free from forgetting to erase data, which is very effective for a portable terminal having a small answering machine recording area.

According to the fourth aspect of the present invention, the predetermined time can be set according to the priority of the caller. For important data having a high priority, the predetermined time is extended and data having a low priority is set. Can be shortened for a certain period of time, so that the terminal user can select data according to the caller. In addition, applications such as setting the time until data erasure to infinity or zero can be made. When set to infinity, the data will not be deleted unless the terminal user deletes it by himself, which is effective when the user wants to save the data. Conversely, if set to zero,
Since the data is erased immediately after the data is recorded, it is substantially the same as that the data is not recorded, and the terminal user can select the sender who can record the data.

According to the fifth aspect of the present invention, it is determined whether or not the data recorded by the answering machine function has been reproduced, and when the data has been reproduced, the data can be erased after a certain period of time. Can be prevented from being erased. Therefore, the terminal user is freed from the trouble of erasing the data by himself. It also frees you from forgetting to erase data. In addition, since the reproduction determining means is provided, the situation that data is erased due to timeout before listening to data is released.

According to the sixth aspect of the present invention, the predetermined time can be set according to the priority of the caller.
For data with low priority, the fixed time can be shortened, so that the terminal user can save important data for a long time depending on the caller, and can select data by immediately deleting non-important data.
