[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables a portable communication terminal to communicate with a wireless base station to record a call memo for making a call with the other party, and to listen to the call memo using the terminal after the call ends. Communication system.

[0002]

2. Description of the Related Art A system for making a call to a destination, recording the contents of the call, and confirming the contents later is provided with a call recording means such as a magnetic tape at a terminal, without any special operation by a terminal operator. There are a method of recording the entire call content and a method of starting the recording of the call content by the key operation of the terminal operator.

Further, in a mobile communication system in which a portable communication terminal communicates with a wireless base station to talk with the other party, the area where the radio wave transmitted from the wireless base station to the terminal reaches sufficiently is limited. However, depending on the position of the terminal within the area, the transmission / reception state of the terminal changes due to the distance difference between the wireless base station and the terminal, the battery consumption of the terminal, the presence or absence of radio wave interference, and the like.

[0004]

In the former method of recording the contents of a call with the other party, the recording means has a large capacity for recording all the contents of the call, and in order to be built in the terminal, one call is required. It is necessary to keep the allocated storage capacity within a predetermined capacity, and in that case, there is a problem that sufficient call contents cannot be recorded. In addition, the latter method allows a key operation depending on the intention of the terminal operator, so that it is possible to use a recording means that has a smaller capacity than the former, in that only the required calls need to be recorded, but recording for a long time is still possible. Is impossible.

[0005] Further, especially in a mobile communication terminal, there is a case where a person may fall into a deafness state due to radio wave interference or the like, and in that case, there is a demand to confirm the call of the other party later.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a communication system capable of listening to a call memo provided with a memory capable of recording a sufficient recording capacity as a call memo. Another object of the present invention is to provide a communication system capable of listening to a call memo that allows the call memo to be reproduced by operating a terminal.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a portable communication terminal is used to record a call memo for communicating with a wireless base station and a call is made with the other party. The communication system is audible, and is configured to record the call memo in the memory of the wireless base station.

Further, it is preferable that the memory is shared with an electronic mail memory. In addition, the call memo,
It is preferable to record all calls once and save them by a save signal from the terminal. It is preferable that the call memo is recorded by a call memo recording request signal from the terminal. Further, it is preferable that the call memo is deleted by a call memo deletion request signal from the terminal.

[0009]

According to the present invention, when a mobile communication terminal is used to communicate with a wireless base station and a call is started with the other party, the content of the call is recorded as a call memo in a memory provided in the wireless base station. Since this call memo is recorded in the memory of the wireless base station, the call memo can be left in a large capacity memory as compared with the case where it is built in the terminal, and the whole call can be recorded.

Further, when the memory is configured to be shared with the e-mail memory, it is not necessary to separately provide a memory for the call memory, and the e-mail memory can be shared for efficient use.

Further, if the call memo is configured to record all the calls once and save them by the save signal from the terminal, all the calls are recorded for each call. There is no omission of recording even when you want to record.

When the call memo is recorded by a call memo recording request signal from the terminal,
There is no need to record unnecessary call memos, and there is no need to prepare a large-capacity memory.

When the call memo is deleted by a call memo deletion request signal from the terminal, the call memo after the call memo is reproduced is not saved in the recorded state forever and the memory is effective. It can be used to prevent large capacity.

Further, the CPU 21 is connected to a telephone line interface unit 25 connected to a business operator network 41 (FIG. 1) to communicate with a telephone terminal and other data management center 40.

The CPU 21 is also connected to a data transmitting / receiving unit 26 for recording various data received from the telephone line interface unit 25 in the information data memory 28. The data in the information data memory 28 is configured to be searched and heard from the terminal via the communication unit 24, the data transmission / reception unit 27, and the information data search circuit 27. In addition, the ROM 23 connected to the CPU 21
Stores a program for processing transmission / reception and other functions in a predetermined flow.

Further, the data transmitting / receiving unit 27 has a memory 31.
Is connected to the memory 31. The memory 31 stores a message for an electronic mail of the communication terminal 1 and a call memo received via the wireless communication circuit 24. Further, the terminal output level arithmetic circuit 30 connected to the information data memory 28 and the data transmitting / receiving unit 27 measures the output level of the position registration information received from the data transmitting / receiving unit 27, and outputs a control signal via the data transmitting / receiving unit 27. And the information data memory 28 stores the output level state of the terminal.

The arithmetic circuit 30 has an output level L of the terminal.
Let t, the reference upper limit value Lmu, and the reference lower limit value Lml be L
mu ≧ Lt ≧ Lml and the terminal output level is controlled so as to be between the reference values. When the terminal output level is equal to or lower than the reference lower limit value, an output up signal is transmitted and the terminal output level is equal to the reference upper limit value. When the terminal output level does not exceed the reference lower limit value, an adjustment-disabled signal or an output level reduction signal is transmitted when the terminal output level does not exceed the reference lower limit value.

Next, the outline of the output level adjustment procedure of the terminal used in this embodiment will be described with reference to FIG. When the power switch 10 (FIG. 1) of the communication terminal A is closed, a position registration request is transmitted (50), and the base station 20 receives the position registration request signal (51). The terminal output level calculation circuit 30 of the base station 20 measures the terminal output level, and when the output level is not within the predetermined range, a control signal is transmitted (52).

In the terminal which has received the control signal, the output level adjusting circuit 18 adjusts the output level (53), and the position registration request signal is transmitted. After the exchange of the control signal and the location registration request signal within a predetermined time, when the output level of the terminal does not rise to within the reference value, it is determined that the terminal output level arithmetic circuit 30 of the base station cannot adjust, A terminal output adjustment impossible notification is transmitted (54). The terminal receiving the disabling notification displays a mark in the form of a battery on the display unit and blinks and flashes the mark (55).

When a calling signal is transmitted from the terminal (56) and the base station 20 receives the calling signal of the terminal (57), if the terminal output level cannot be adjusted by the position registration request signal, the terminal output level is adjusted. An unadjustable notification is transmitted and a call response (58) is made. The terminal receives the terminal output level adjustment inability signal, displays the battery level on the display unit 4 by voice along with the output level adjustment inability warning, and flushes the mark (59).

Ignoring this warning, when the terminal transmits the telephone number of the other party (60), the base station 20 receives the telephone number (61) and issues a call signal to the other terminal (6).
2) Do it. The terminal (63) which receives this calling signal, terminal B
If the owner of the device is not nearby, it rings the doorbell,
If busy, a busy signal is transmitted (64).

FIG. 6 is an explanatory diagram of the operation procedure of the voice mail (electronic mail) function. In the figure, when the busy signal from the terminal B is transmitted 15 times (65), the base station confirms the signal (66) and notifies the terminal A of the voice mail reception (67). At this time, if the output level of the terminal A cannot be adjusted, the warning is given by voice and flashing of the display unit. For example, by voice, "I can't adjust because the output of your terminal is low, but I cannot accept the voicemail, so I will accept voicemail."

A message for voice mail and a calling time are designated from the terminal (69). For example, after pressing the function key 7d of the terminal 1 and transmitting a message,
Using the # key, the meaning of 1:00 pm on the 14th is ((#
1413 #) is operated by key input. When the base station 20 receives the message contents and the calling time, the memory 31
It is stored and stored in (70) and a call is made to the terminal B on the designated date and designated time (71).

(72) Terminal B receiving this calling signal
Sends an off-hook signal (73), and when the base station 20 receives the signal (74), sends a message (7).
5) When the terminal B receives the message (76) and transmits the on-hook signal (77) and the base station 20 receives the on-hook signal (78), the base station 20 erases the message content (79). , End (80).

FIG. 7 is an explanatory view of the first half of the operation procedure for explaining the operation of the call memo function. In the figure, when the terminal A sends the destination telephone number (60), the terminal B sends an off-hook signal (81), and a call is started (84), the call memo is stored in the memory 31 of the base station 20. Recording begins (8
5). When the call ends (86) and the call memo key 7c of the terminal 1 is pushed, a save signal for requesting save as a call memo is transmitted (87). Upon receiving this storage signal, the base station 20 gives a storage number to the call memo, notifies the terminal of the storage number, and stores the call memo (8
9). When the terminal receives the storage number, it stores it in the memory 12 (90). If there is no storage request from the terminal A or B, it is appropriately deleted.

FIG. 8 shows a call memo reproduction procedure which is the latter half of the operation procedure of the call memo function. In the same figure, when the playback key 7e and the call key 5a are pressed in a state in which the call memo storage number is displayed on the display unit 4 of the terminal 1, the call is played back together with the call and the storage number is transmitted (94), A memo playback request is made. Upon receiving the reproduction request (95), the base station 20 searches the memory 31 by the storage number from the information data search circuit 29 and sends the call memo to the terminal (96).
I do.

When the reproduction and listening of the call memo are completed (9
8), the terminal sends a call memo deletion signal, for example, # 000 #
When the call memo deletion signal is received (100), the terminal A and B check that the call memo is not required (101), the contents of the call memo are erased and the process ends. 103). Even if the call memo deletion signal is not received from the terminal, the storage number request is deleted in consideration of the storage capacity of the memory 31 as in the case where the storage number request is inward.

Next, the flow of this embodiment in the base station 20 will be described in detail with reference to FIGS. In FIG. 9, when the power switch 10 (FIG. 2) of the terminal 1 is pressed, a terminal location registration request signal is transmitted, and when the base station 20 receives the location registration request signal (151), it is determined whether or not there is a calling signal. (102) If the calling signal is received, and further, the playback key and the storage number of the call memo are received (15).
3), step C assuming that a call memo playback request has been issued
If the reproduction request is not made, it is judged whether the terminal output level measurement is completed (15).
4) If yes, go to step B.

If the calling signal from the terminal is not received (1
52) Also, when the terminal output level measurement is not completed (154), the terminal output level measurement (155) is performed. If the terminal output level is within the normal range, the device returns to the standby state (150), but if it is not within the normal level, an output level adjustment command (157) is issued and the location registration request signal of the incoming terminal is issued. The output level of (158)
If the terminal output level is not within the normal range, it is determined whether the output level adjustment is completed, for example, whether a predetermined time has passed (160). If the adjustment is not completed, steps 157 and 158 are performed. If the output level adjustment is completed and the output level adjustment is impossible (161), the output adjustment impossible notification is sent to the terminal (162) and the standby state is returned (150).

Next, the flow of the base station when the terminal makes a call will be described. In FIG. 9, the terminal output level measurement is completed (15
4), the process proceeds to step B in FIG. FIG.
At 0, when the terminal output level cannot be adjusted,
The above-mentioned warning is sent to the terminal (164), and a warning instruction is given to the voice and the display unit. When a call is made from the terminal and the other party's telephone number is received (166), the base station 20 makes a call to the other party's terminal (167) and receives the off-hook signal (1
68) The content of the call is recorded (169). When the call ends and the save signal is received from the terminal, the save number is transmitted and the state returns to the standby state (150). Also, from terminal A,
When the save signal is not received from B as well, FIG.
The process proceeds to step E of 2 and the memo contents are erased.

In FIG. 10, when the base station 20 calls the other party (167) and the off-hook signal of the other party terminal is not received (168), the process proceeds to step D (105). . In FIG. 11, the busy signal is changed to 15
If the output level of the terminal A is not adjustable (173) after receiving the number of times (172), the terminal A is warned (174) and a message reception signal is transmitted (106). Reception of the message is started (176), the message from the terminal is received, and the message recording is completed (177). At the designated time of the terminal, a message is sent to the destination terminal (178), and when the message communication is completed (179), the content of the message is deleted (180) and the processing is ended (181).

Next, the operation of the base station when transmitting a call memo will be described with reference to the flowchart of FIG. In FIG. 9, when the call memo reproduction request and the storage number are received together with the call signal of the terminal (153), the process proceeds to step C of FIG. When the memo content is transmitted (182) and the memo transmission is completed (183), it is judged whether or not the memo deletion signal is received from the terminal A (184), and if the deletion signal is received, it is the other party. It is determined whether the terminal B has requested the storage of the call memo (185), and if the storage request is made, it is determined whether the memo deletion signal is received from the terminal B (186) and the memo deletion signal is received. When the message is received, the contents of the memo are erased (189) and the process is ended (190).

On the other hand, it is conceivable that both the terminal A and the terminal B forget the transmission of the erase signal or leave them as they are for the purpose of reproducing again later. Therefore, in such a case, when a predetermined time, for example, 24 hours has passed, the contents of the call memo are automatically deleted. That is, as shown in FIG. 12, when the memo deletion signal is not received from the terminal A (184), after a predetermined time elapses (187), and when the memo deletion signal is not received from the terminal B (188), The content of the memo is erased (189).

In the above embodiment, the busy signal of the other party is detected and the voice mail is accepted at the terminal. However, the present invention is not limited to this, and the voice message key 7d of the terminal is operated. Then, it may be accepted at the request of the terminal. Also, it is explained that the call memo is recorded for all calls, and those that have been requested to be saved are saved, and those that are not requested are deleted. A call memo request signal may be sent for recording operation.

In this embodiment, the memory 31 in the wireless base station is disclosed as the memory of the wireless base station. However, the memory 31 is not limited to this, and may be an external memory wiredly connected to the wireless base station. Needless to say, the memory may be a wirelessly connected memory that is guaranteed not to cause radio interference.

As described above, according to such an embodiment,
Since the call memo is recorded in the memory of the wireless base station, the call memo can be left in a large capacity memory as compared with the case of being built in the terminal, and the whole call can be recorded. Further, since the memory can be configured to be shared with the e-mail memory and it is not necessary to separately provide a memory for the call memory, it can be shared with the e-mail and used efficiently.

Further, when the call memo is configured to record all calls once and save the call memo by the save signal from the terminal, all calls are recorded for each call. There is no omission of recording even when you want to record. When the call memo is recorded by a call memo recording request signal from the terminal,
There is no need to record unnecessary call memos, and there is no need to prepare a large-capacity memory. Further, since the call memo is configured to be deleted after a call memo deletion request signal from the terminal or after a predetermined time, the call memo after playing the call memo is not saved in a record state forever.
It is possible to effectively use the memory and prevent the increase in capacity.

[0048]

As described above, according to the present invention,
Call memo that can be played by operating the terminal,
Since it is recorded in the memory of the wireless base station having a sufficient recording capacity, the call memo can be heard again in a place where the radio wave condition is good.
