[0002]
[Prior art]
Mobile terminals such as mobile phones and PHSs are widely used because they can easily make a phone call anywhere and indoors.
By the way, in the portable terminal mentioned above, the thing provided with the mail function which can transmit / receive a character message etc. between portable terminals other than the original voice call is provided by recent technological innovation. If this is used, the user who owns the mobile terminal can communicate with the other party by voice or text message.
[0003]
[Problems to be solved by the invention]
Now that the use of mobile terminals has permeated various life situations, in addition to the communication function by voice or text message, the mobile terminal is required to have a function that can facilitate simpler communication.
As an example of performing simple will transmission, for example, it is conceivable that the user knows whether or not the other party is ready to answer the phone before making a call request.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention are described below. Such an embodiment shows one aspect of the present invention, and is not intended to limit the present invention, and can be arbitrarily changed within the scope of the present invention.
[0008]
(1) Configuration of the embodiment
First, FIG. 1 is a block diagram showing a circuit configuration of a mobile terminal according to the present embodiment.
As shown in FIG. 1, the mobile terminal 100 of the present embodiment includes a wireless unit 11, a storage unit 14, a control unit 12, a vibration detection unit 16, a vibration reproduction unit 17, a key input unit 13, a display unit 15, and a timer 18. Have.
The portable terminal 100 is a known portable terminal provided with a vibration detection unit 16 and a vibration reproduction unit 17.
[0009]
A wireless unit 11 shown in FIG. 1 is means for performing bidirectional wireless communication with a center (not shown), and a transmission / reception antenna 11a is connected to the wireless unit 11.
The control unit 12 is a control center of the mobile terminal, and controls each unit in the mobile terminal 100 according to various control programs stored in the program memory 14 a of the storage unit 14.
The key input unit 13 is composed of input keys (not shown) of numbers and various characters (alphabet characters) and the like, and inputs data such as telephone numbers by operating the input keys.
The storage unit 14 includes a program memory 14a and a data memory 14b.
The program memory 14a is a non-volatile memory and serves as a storage means for various control programs and control information. The program memory 14 stores a processing program and the like for transmitting data output from a vibration detection unit 16 described later to the counterpart portable terminal.
The data memory 14b is a rewritable memory and stores data output from the vibration detection unit 16 (details will be described later).
The display unit 15 is a means for displaying characters, symbols, and the like selected by the user operating the key input unit 13, and is configured by a liquid crystal panel or the like.
[0010]
Next, the vibration detection unit 16 and the vibration reproduction unit 17 will be described with reference to FIG.
FIG. 2A is a diagram illustrating an appearance of the mobile terminal 100.
The portable terminal 100 is provided with an openable / closable flip 110 that is pivotally supported at an end of the portable terminal 100. The flip 110 covers an operation button (not shown) in the closed position. A hitting surface portion 111 is provided on the surface of the flip 110. When the user strikes the striking surface portion 111, the striking strength is detected by the vibration detection unit 16.
[0011]
The vibration detection unit 16 includes a pressure sensor 16a that detects a pressure applied to the striking surface portion 111, and a pressure detection circuit 16b that outputs pressure detection data based on a signal output from the pressure sensor 16a. Details of the pressure sensor 16a and the pressure detection circuit 16b will be described later.
In the following description, hitting the striking surface portion 111 is referred to as knocking, and a signal output from the pressure sensor 16a by knocking is referred to as a knocking signal.
Data indicating the strength of knock output from the pressure detection circuit 16b is referred to as knock data.
[0012]
FIG. 2B is a cross-sectional view taken along line AA ′ of the flip 110 shown in FIG.
As shown in FIG. 2B, the pressure sensor 16 a is provided on the lower surface of the striking surface portion 111, and outputs a signal that changes according to the strength of the striking applied to the striking surface portion 111. That is, if the strength of the impact is large, the amplitude of the knock signal increases. The knock data output from the pressure detection circuit 16b also changes in accordance with the change in the knock signal.
However, the pressure detection circuit 16b detects a knock signal of a predetermined level (threshold value) or more and outputs knock data. Therefore, when a slight pressure is applied to the striking surface portion 111 against the user's intention when knocking is input (for example, a clothes collar is touching the striking surface portion 111), a minute amount is applied from the pressure sensor 16a. Even if the knock signal indicating the change is output, the knock data indicating that the pressure has been hit is not output from the pressure detection circuit 16b.
[0013]
Further, the pressure sensor 16a detects only the pressure applied to the striking surface portion 111 as described above. Therefore, even when vibration is applied to the entire mobile terminal 100 (for example, when a user who puts the mobile terminal 100 in a pants pocket runs down the stairs, etc.), pressure is applied to the striking surface portion 111. Unless otherwise, a knock signal indicating a pressure change is not output from the pressure sensor 16a.
Thus, since the control unit 12 of the mobile terminal 100 according to the present embodiment determines the presence or absence of knock input from the pressure change applied to a specific surface (striking surface portion 111), vibration applied to the entire mobile terminal 100 Is not mistakenly recognized as a knock input.
[0014]
Next, the vibration reproducing unit 17 will be described.
The vibration reproducing unit 17 is a circuit that reproduces a knock in accordance with knock data or the like sent from another mobile terminal, and includes a striking mechanism (not shown) such as a piezoelectric vibrator.
This striking mechanism is provided inside the mobile terminal 100 (not shown), and accurately reproduces the striking strength of the striking and the striking interval (time interval from striking to the next striking) by the process described later. Then, the vibration is transmitted to the entire mobile terminal 100.
Therefore, even when knock playback is performed while walking with the mobile terminal 100 in the pocket, the vibration due to the knock playback is transmitted to the entire mobile terminal 100, so that the user can experience the vibration. .
Here, a hitting mechanism such as a piezoelectric vibrator that dynamically hits the portable terminal 100 as the knock reproducing means is illustrated, but the invention is not limited thereto.
For example, a speaker may be used as the knock reproducing means, and the vibration may be reproduced by amplifying and frequency-converting the received signal in accordance with knock data transmitted from another portable terminal.
[0015]
In this way, the vibration reproduction unit 17 performs knock reproduction based on knock data or the like transmitted from another portable terminal, whereby vibration due to knock reproduction is transmitted to the entire portable terminal 100.
Here, the relationship between the vibration detection unit 16 and the vibration reproduction unit 17 will be described.
The vibration detection unit 16 detects the striking strength only when the striking surface portion 111 is hit as described above. Therefore, even when the vibration reproduced by the vibration reproducing unit 17 is transmitted to the entire mobile terminal 100, data indicating that a knock input has been made is output from the vibration detecting unit 16 unless pressure is applied to the striking surface unit 111. Never happen.
Therefore, the control unit 12 does not misrecognize vibration caused by knock reproduction as knock input.
Next, the premise at the time of transmitting / receiving knock data etc. using the portable terminal 100 mentioned above is demonstrated.
[0016]
(2) Prerequisites for operation explanation
i) Communication method
First, the data communication system in this embodiment will be described.
In the present embodiment, a wireless packet communication method is employed in which knock data or the like is packetized and data is transmitted and received.
The packet communication here is premised on a connection-type data communication method in which a connection is established (hereinafter referred to as establishing a call) and data is sent over the established connection when communication is performed between terminals. A connection refers to a connection between terminals for performing communication.
[0017]
FIG. 3 is a diagram showing a schematic configuration of the communication system in the present embodiment.
The communication system shown in FIG. 3 includes a mobile terminal 100a, a dedicated center (hereinafter simply referred to as a center) 200 for distributing knock data and the like, and a mobile terminal 100b.
The center 200 serves as a communication network (network) for portable terminals, and may be provided as a special function of a general exchange or as a dedicated exchange.
[0018]
In FIG. 3, when knock data or the like packetized is transmitted from the mobile terminal 100a, the center 200 first receives the knock data or the like. The center 200 transmits knock data or the like from the mobile terminal 100a to the mobile terminal 100b.
When transferring knock data or the like between the portable terminal 100a and the portable terminal 100b via the center 200, first, a call is established between the center 200 and the portable terminal 100a, and the center 200 is set while the call is established. Send knock data, etc. Then, after the call is disconnected and a call is established between the center 200 and the portable terminal 100b, knock data or the like is transmitted from the center 200 to the portable terminal 100b.
Here, when the knock data and the like are exchanged between the portable terminal 100a and the portable terminal 100b, the state where the call is established between the center 200 and the portable terminal 100a and between the center 200 and the portable terminal 100b is held. Thus, data may be directly exchanged between the portable terminal 100a and the portable terminal 100b.
[0019]
As described above, the connection type communication method is adopted in this embodiment, but a connectionless type communication method represented by the Internet Protocol (IP) may be adopted. Here, the connectionless communication method refers to a communication method in which it is not necessary to establish a call between terminals that transmit and receive data, and transmission and reception are always possible.
Next, a transmission mode set by the user when transmitting knock data or the like will be described.
[0020]
ii) Transmission mode
First, there are two types of transmission modes: immediate transmission mode and post-recording transmission mode.
Here, the immediate transmission mode refers to a transmission mode in which data related to the knock input is sequentially transmitted after the knock input, and the post-recording transmission mode refers to the data related to the knock once stored in the data memory 14b after the knock input. This refers to the transmission mode that transmits after a lapse of time. Specifically, it is as follows.
[0021]
First, the immediate transmission mode will be described.
FIG. 4 is a diagram illustrating an example of the operation in the immediate transmission mode.
First, it is assumed that the user knocks the striking surface portion 111 with a finger (FIG. 4A).
When the striking surface portion 111 is knocked, a knock signal nc1 corresponding to the knock is output from the pressure sensor 16a (FIG. 4B). The pressure detection circuit 16b obtains the knock strength from the signal level of the knock signal nc1, and outputs the knock data nd1 (FIG. 4C). Then, the knock data nd1 is transmitted from the wireless unit 11 of the portable terminal 100 via the antenna 11a (FIG. 4D).
The series of processes described above are repeatedly executed for each knock input.
For example, when knocking is input four times in the immediate transmission mode, knock data nd1 to nd4 (FIG. 4 (f)) indicating the strength of the knock corresponding to each knock are sequentially transmitted from the radio unit 11 via the antenna 11a. (FIG. 4E).
[0022]
In this way, the immediate transmission mode in which knock data is transmitted sequentially is a transmission mode that emphasizes immediacy. In this immediate transmission mode, when a delay occurs in the transmission path for transmitting knock data, the knock timing (time interval from the input of a knock until the next knock is input) on the transmission side and the knock on the reception side. There will be a deviation from the knock timing during playback. That is, the knock interval may not be accurately reproduced.
Next, the post-recording transmission mode will be described.
[0023]
FIG. 5 is a diagram illustrating an example of the operation in the post-recording transmission mode.
First, when the striking surface portion 111 is knocked, knock data nd1 corresponding to the knock (first knock) is output from the pressure detection circuit 16b and the timer 18 is reset (FIG. 5B). The timer 18 starts measuring time at the same time that the hitting surface portion 111 is knocked, and notifies the control portion 12 when a predetermined time T has elapsed. In this post-recording transmission mode, knock data and timer 18 time data are stored in association with the data memory 14b.
Therefore, here, the knock data nd1 and the knock timing data t1 (t1 = 0) indicating the time measured by the timer 18 are temporarily stored in the data memory 14b without being transmitted.
Then, if there is no knock input before the predetermined time T elapses after knocking the striking surface portion 111 for the first time, the knock data nd1 and the knock timing data t1 are transmitted from the radio unit 11 after the elapse of the predetermined time T (FIG. 5 (a)). In the following description, a state from when a knock is input until a predetermined time T has elapsed is referred to as a knocking state.
[0024]
Here, as shown in FIG. 5 (c), if the next knock (second knock) is input before the predetermined time T has elapsed since the knocking surface portion 111 was knocked first, Knock data nd2 corresponding to the first knock and knock timing data t2 with the time when the first knock is input as “0” are stored in association with the data memory 14b in the same manner as described above.
The timer 18 is reset and time measurement is newly started. If there is no knock input after the second knock is input until the predetermined time T has elapsed, the knock data nd1, nd2 and the knock timing data t1, t2 stored in the data memory 14b are collected from the radio unit 11 together. It is transmitted (FIG. 5 (d)).
[0025]
Thus, in the post-recording transmission mode, knock data indicating the strength of the knock and knock timing data indicating the relative time with the time when the first knock is input as the origin are stored in the data memory 14b. The
If the next knock is not input before the predetermined time T elapses, the knock data stored in the data memory 14b and the knock timing data are transmitted together (FIGS. 5C and 5D). ).
The mobile terminal 100 on the receiving side reproduces the knock according to the received knock data and the knock timing data. Therefore, there is no deviation between the knock timing on the transmission side and the knock timing at the time of knock reproduction on the reception side.
Next, the type of transmission data will be described.
[0026]
iii) Types of transmission data
FIG. 6 is a diagram illustrating the relationship between the transmission mode and the transmission data.
As is apparent from the above description, the configuration of transmission data differs depending on the type of transmission mode.
When the transmission mode is the immediate transmission mode, the transmission data is only knock data.
On the other hand, when the transmission mode is the post-recording transmission mode, the transmission data is knock data and knock timing data.
In the following description, transmission data in the immediate transmission mode is referred to as single knock data, and transmission data in the post-recording transmission mode is referred to as knock sequence data.
A type code (for example, a code for changing the vibration frequency) may be added to each transmission data, and the type of vibration may be changed depending on the position where the hitting surface portion 111 is hit. Here, as a method for detecting the position where the striking surface portion 111 is struck, for example, a plurality of pressure sensors may be provided for the striking surface portion 111, and a unique vibration frequency may be assigned to each pressure sensor.
Based on the above-mentioned premise, the operation of the embodiment will be described.
[0027]
(3) Explanation of operation of embodiment
i) Transmission processing
Next, an operation when data is transmitted using the mobile terminal 100 having the above-described configuration will be described with reference to FIGS. In the following description, simply referring to data means data relating to knocking. Here, a case is assumed in which packet data is transmitted using a system in which a mobile terminal of a transmission partner such as a PDC-P system that is currently widely used cannot directly receive packet data from a transmission source.
FIG. 7 is a flowchart showing the operation of the control unit 12 during data transmission.
Here, a case where the user selects the immediate transmission mode will be described first.
[0028]
a) Immediate transmission processing
First, the user operates the input button to input the telephone number of the transmission partner, and then sets the transmission mode to the immediate transmission mode. When the transmission mode is set to the immediate transmission mode, the control unit 12 reads the address of the center 200 stored in the data memory 14b, establishes a call with the center 200, and starts packet communication.
Next, the control unit 12 activates the designated immediate transmission mode processing program and enters a knock input waiting state (step S1). Then, the process proceeds to step S2 to determine whether or not there is a knock. Whether or not there is a knock is determined based on knock data output from the pressure detection circuit 16b.
When the knock data is output from the pressure detection circuit 16b while the processes of Step S1 and Step S2 are repeated and it is determined that there is a knock (Step S2), the knock data is stored in the data memory 14b, and the process proceeds to Step S3. In step S3, the control unit 12 resets the timer 18 (T = 0).
[0029]
In step S4, it is determined whether the network side is ready for transmission. Here, transmission preparation means establishing a call between terminals that exchange data (between the center 200 and the portable terminal 100a of the user who is the transmission source).
If it is determined in step S4 that network transmission is ready, the process proceeds to step S5. In step S5, the control unit 12 determines whether or not the transmission mode set by the user is the post-recording transmission mode. Since the transmission mode set by the user is the immediate transmission mode, the determination result is “No”, and the process proceeds to step S6. The control unit 12 reads knock data (knock strength) from the data memory 14b, and sends the knock data to the radio unit 11 (step S6). In response to this, the wireless unit 11 transmits single knock data composed of knock data for immediate transmission to the other mobile terminal via the antenna 11a.
[0030]
And it returns to step S1 again and repeats the process of step S1-step S6. During this time, when the user performs a button operation on the portable terminal 100 and the setting mode is switched from the immediate transmission mode to the call mode or the like, the control unit 12 ends the transmission process.
[0031]
Here, when the center 200 receives the single knock data from the user's portable terminal 100a, the center 200 specifies the portable terminal 100b that is the destination of the single knock data from the telephone number of the transmission partner input by the user, and the transmission destination portable terminal. A call is established with 100b.
When the center 200 establishes a call with the destination mobile terminal 100b, the center 200 transfers the single knock data sent from the user's mobile terminal 100a to the mobile terminal 100b. Even if a call is established with the center 200, the mobile terminal 100 b does not sound an incoming ring tone to notify an incoming call, and sequentially reproduces knocks according to the single knock data sent from the center 200.
[0032]
Next, the case where the user selects the post-recording transmission mode will be described with reference to FIG. 8 based on the following conditions.
<Conditions>
1: The predetermined time T measured by the timer 18 is “30”.
2: When the pressure detection circuit 16b detects knock, the minimum value of the knock data nd is “1”, and the maximum value is “10”.
[0033]
b) Transmission process after recording
The user operates the input button to specify the destination and to set the post-recording transmission mode immediate transmission mode. The control unit 12 activates the designated post-recording transmission mode processing program. Then, the controller 12 enters a knock input standby state (standby state) (step S1), and determines whether or not there is a knock (step S2).
While the processes of step S1 and step S2 are repeated, knock data nd1 (value is set to “7”) is output from the pressure detection circuit 16b as shown in FIG. 8, and it is determined that there is a knock (step S2). The knock data nd1 is stored in the data memory 14b, and the process proceeds to step S3. In step S3, the control unit 12 resets the timer 18 (T = 0). The measured value of the timer 18 at this time, that is, the knock timing data t1 (value is set to “0”) is stored in the data memory 14b in association with the knock data nd1. The timer 18 starts measuring time simultaneously with the reset.
[0034]
In step S4, it is determined whether the network side is ready for transmission. When determining that the network transmission is ready and the transmission mode is the post-recording transmission mode (steps S4 and S5), the control unit 12 proceeds to step S16. The control unit 12 determines whether or not the predetermined time T (T = 30) has elapsed in step S <b> 16 based on the measurement value of the timer 18.
[0035]
Since the timer 18 is reset, the control unit 12 determines that the predetermined time T has not elapsed, and proceeds to step S18. In step S18, the control unit 12 determines whether or not there is a knock. If the control unit 12 determines that there is a knock, the knock data nd2 (value is set to “3”) output from the pressure detection circuit 16b and the measured value of the timer 18 at this time, that is, the knock timing data t2 ( The value is set to “10”) in association with the data memory 14b (see FIG. 8). At this time, the timer 18 is reset (T = 0) and starts measuring time again. Then, the process proceeds to step S16.
[0036]
In step S <b> 16, the control unit 12 determines whether or not the measured value of the timer 18 exceeds a predetermined time T. Since the timer 18 is reset, it is determined that the predetermined time T has not elapsed, and the process proceeds to step S18. Then, it is determined whether or not there is a knock.
If it is determined in step S18 that there is no knock, the process returns to step S16 again. If the time measured by the timer 18 exceeds the predetermined time T (value is set to “30”) during the repeated execution of the processes of step S16 and step S18, the process proceeds to step S17. In step S17, the control unit 12 reads the knock data nd1 and nd2 stored in the data memory 14b and the knock timing data t1 and t2 corresponding to the knock data, and collectively sends them to the radio unit 11 (see FIG. 8A). In response, the wireless unit 11 transmits knock sequence data including a plurality of knock data and knock timing data for transmission after recording to the other mobile terminal via the antenna 11a.
[0037]
And it returns to step S1 again and repeats the process of step S1-step S5 and step S16-step S18. During this time, when the user performs a button operation on the portable terminal 100 and the setting mode is switched from the recorded transmission mode to the call mode or the like, the control unit 12 ends the transmission process.
[0038]
Here, the operation of transmitting knock sequence data from the center 200 to the transmission destination portable terminal 100b is the same as the operation of transmitting single knock data from the center 200 to the transmission destination portable terminal 100b in the above-described immediate transmission mode. Therefore, the description is omitted.
[0039]
The transmission process described above is a connection process transmission process.
As described above, in the connection-type communication system, when data is exchanged, it is necessary to first establish a call between the terminals that exchange data, specifically, between the center 200 and the source portable terminal 100a. Yes (see FIG. 3).
Therefore, when a knock is input when the transmission is not ready (before establishing a call between the center 200 and the transmission source portable terminal 100a), it is recorded whether the transmission mode set by the user is the immediate transmission mode. Regardless of whether it is the post-transmission mode, the mode shifts to the post-recording transmission mode (see step S4 shown in FIG. 7).
[0040]
Here, as described above, there are various methods for dealing with a case where a knock is input when the preparation for transmission is not completed, in addition to the method for shifting to the post-recording transmission mode.
For example, there is a method in which if a knock is input before the transmission preparation is completed, an error is detected and the knock input is not accepted until the transmission preparation is completed.
Specifically, when a knock is input before the preparation for transmission is completed, the user is notified that the transmission is not possible, for example, by displaying it on the display unit 15. Then, after the transmission preparation is completed, the user is notified again that the transmission preparation is completed.
As described above, knock input may not be accepted until preparation for transmission is completed.
[0041]
iii) Reception processing
Next, the operation on the receiving side for receiving data will be described with reference to FIGS.
FIG. 9 is a flowchart showing the operation of the control unit 12 at the time of data reception.
First, when data is sent from the center 200, the mobile terminal 100b on the receiving side determines whether or not the sent data is single knock data based on header information or the like (step S100 → step S101). . If the control unit 12 determines that the received data is single knock data, the control unit 12 sequentially reproduces knocks (step S102). Specifically, a control signal is output to the vibration reproducing unit 17 in accordance with knock data (knock strength) constituting the single knock data. The striking mechanism of the vibration reproducing unit 17 performs striking according to this control signal and transmits the vibration to the entire mobile terminal 100.
[0042]
On the other hand, when it is determined that the data sent from the center 200 is knock sequence data (step S101), the knock sequence data is temporarily stored in the data memory 14b. Then, the knock data and the knock timing data constituting the knock sequence data are read from the data memory 14b, and the knock having the strength corresponding to the knock data is reproduced according to the knock timing data. Since the specific operation of knock reproduction is the same as that of single knock data, description thereof is omitted.
As described above, knock sequence data includes knock timing data. By the above processing, there is no deviation between the knock timing at the time of knock input and the knock timing at the time of knock reproduction.
[0043]
Here, the mobile terminal 100 according to the present embodiment has an automatic destination change function that automatically changes the destination for the next call to the source of the knock data when receiving data related to the knock. . More specifically, when the portable terminal 100 receives data related to knocking, the control unit 12 reads a caller number included in the received data. Then, this caller number is stored in the data memory 14b as the telephone number of the knock transmission destination. When the transmission mode is set by the user, the control unit 12 sets the telephone number stored in the data memory 14b as the destination of data related to knocking.
Therefore, when the user who has received the knock returns the knock to the knock transmission source after following the communication, the telephone number stored in the data memory 14b is not input without inputting the telephone number of the knock transmission destination. Can read back a knock.
[0044]
iv) Processing for signal interruption
In the present embodiment, data is exchanged between the mobile terminals 100a and 100b via the center 200 as shown in FIG.
Here, the center 200 can establish (connect) a call with a plurality of terminals. For this reason, data may be sent from another portable terminal (other than 100a and 100b shown in FIG. 3) to the portable terminal 100a or 100b (a signal interruption occurs).
In addition, when data is being transmitted from the mobile terminal 100a to the mobile terminal 100b illustrated in FIG. 3, data may be transmitted from the mobile terminal 100b to the mobile terminal 100a.
The signal interrupts described above can be broadly classified into reception interrupts for transmission and reproduction interrupts from a plurality of transmission sources. Below, the processing method in each case is demonstrated.
[0045]
a) Reception interruption for transmission
Here, a case where the user receives knock sequence data or single knock data (hereinafter simply referred to as “knock”) while transmitting the knock will be described.
(1) When the transmission mode is post-recording transmission mode
First, when a user performs a knock input, if a knock arrives in a knocking state (before a predetermined time T), the incoming knock is played back (interrupt playback is permitted), or the incoming knock is played back after a predetermined time T has passed. (Interrupt playback refusal) is set by button operation.
Here, when the user sets the interrupt reproduction permission, the incoming knock is sequentially reproduced independently of the knock input. On the other hand, when the interrupt reproduction rejection is set, the data related to the incoming knock is temporarily stored in the data memory 14b. Then, when the knock input is finished (the knocking state is finished (predetermined time T has elapsed)), the control unit 12 starts control for reproducing the incoming knock, and receives the incoming call based on the data stored in the data memory 14b. Play the knock.
[0046]
(2) When the transmission mode is immediate transmission mode
As in the case described above, the user sets interrupt playback permission or interrupt playback rejection by operating a button.
When the user sets the interrupt reproduction permission, the incoming knock is sequentially reproduced independently of the knock input as in the post-recording transmission mode.
On the other hand, when the interruption reproduction rejection is set, the data related to the incoming knock is temporarily stored in the data memory 14b. Then, after the transmission process is completed (for example, the setting mode of the portable terminal 100 is switched from the transmission mode to the voice call mode or the like), the incoming knock is reproduced.
[0047]
b) Playback interruption from multiple sources
Next, processing when a knock is sent from a plurality of transmission sources will be described.
[0048]
(1) When knock sequence data is being played
When a knock is sent from another party while the knock sequence data is being reproduced from the sender, the knock interrupt reproduction is not permitted until the reproduction of the knock sequence data being reproduced is completed.
As shown in FIG. 6, knock sequence data is composed of knock data and knock timing data, and guarantees knock timing. During the reproduction of the knock sequence data, the knock timing is guaranteed by not permitting the interrupt interruption reproduction.
[0049]
(2) When playing single knock data
If a knock is sent from another person while reproducing single knock data from the caller, interrupt reproduction is permitted.
As shown in FIG. 6, the single knock data consists of knock data and does not guarantee knock timing. Accordingly, when a knock is sent from another person during the reproduction of the single knock data, the interrupt reproduction is permitted.
However, if there is an interruption knock during single knock data reproduction, the caller number of the knock data transmission source is left as the incoming call history.
For example, when the single knock data is sent from the caller B during the reproduction of the single knock data from the caller A, the knock of the caller A and the knock of the caller B are confused. In this case, it is difficult to specify the transmission source from the knock timing or the strength of the knock. However, the caller number of the knock data transmission source is stored as the incoming call history in the data memory 14b of the mobile terminal on the receiving side.
Therefore, the user can know from whom the knock has been sent by confirming this incoming call history.
[0050]
(4) Other
i) Display method of knock source
When a knock is sent from another portable terminal to the own portable terminal, it is necessary to notify the user of who the knock is sent from. A specific method for notifying the user is as follows.
[0051]
a) Displaying characters and pictures on the display
For example, the sender name is retrieved from the sender number of the knock that is sent, and the corresponding sender name is displayed on the display unit 15.
Here, in order to retrieve the sender name from the sender number, a telephone directory area (memory area in which the sender number and the sender name are stored in association with each other) provided in the data memory 14b is used. .
Therefore, the user can determine who the knock has been sent by confirming the name of the caller displayed on the display unit 15.
[0052]
b) A method of outputting sound, light, etc., for each knocker.
First, the user specifies in advance (hereinafter referred to as “knock conversion designation”) whether a knock is converted into sound for output or output after being converted into light for each knocker.
The portable terminal 100 is provided with a conversion unit (not shown) for converting knock data into sound or light. The conversion unit includes a sound source unit capable of controlling the volume, quality, and pitch of sound, And a light source unit capable of turning on and off.
When a knock arrives at the portable terminal 100, the control unit 12 compares the sender number of the transmitted data with the telephone number stored in the telephone directory area of the data memory 14b to identify the sender. Then, the control unit 12 transfers the data related to the above-described knock conversion specification to the conversion unit. The conversion unit performs reproduction by sound or light according to this data.
For example, when a knock from the caller A is received, the sound is set to sound three times to notify an incoming call with a predetermined rhythm. Further, when a knock from the caller B is received, the display unit 15 is turned on at a predetermined cycle.
By using the above-described setting and the knock reproduction setting together, the user who has received the knock can easily identify who the knock is sent from.
[0053]
c) Method of creating knock sequence data specific to each caller
First, the user freely sets the knock strength and knock rhythm, and creates unique knock sequence data (hereinafter referred to as original knock). When the creation of the original knock is completed, the original knock is stored in the data memory 14b of the mobile terminal 100.
When the user transmits the original knock, the original knock can be transmitted to the mobile terminal of the transmission partner by operating the button without inputting the knock.
On the other hand, the original knock recipient who is the transmission destination of the original knock can specify who the knock is sent from the strength of the knock and the knock timing.
In this way, the original knock recipient can identify the sender from the strength of the knock and the knock timing without confirming the caller number or the like displayed on the display unit 15.
[0054]
ii) Transition from knock reception to other communications
Next, a case where the user who has received the knock performs another communication (for example, voice communication) will be described.
When the knock is received, a timer (not shown) of the mobile terminal 100 that has received the knock is started, and time measurement is started. When the user presses the off-hook button within a predetermined time after the timer is started, the telephone number of the knocking caller is read from the reception knock stored in the data memory 14b and automatically transmitted.
Therefore, the user can perform voice communication with the knocker by a simple operation.
When a knock is transmitted, the telephone number of the knock transmission partner is stored in the data memory 14b for a predetermined period (time is measured using the above-described timer or the like) after the knock is transmitted. Therefore, when the user presses the voice transmission button within a predetermined period, a voice call can be made with the knock transmission partner.
[0055]
iii) Communication guarantee
Next, a method for determining whether or not the knock has reached the transmission partner will be described.
First, the mobile terminal that has received the knock transmits a receipt notification signal to the transmission source.
In the portable terminal on the knock transmission side, a timer (not shown) is reset simultaneously with the knock transmission, and time measurement is started. Then, it is determined whether or not a receipt notification signal is sent within a preset time. When the reception notification signal is received within the set time, it is determined that the knock has arrived at the transmission partner, and the display unit 15 displays that the knock has arrived.
[0056]
On the other hand, if the receipt notification signal is not sent within the preset time, it is determined that the knock has not reached the transmission partner, and the display unit 15 displays that the knock has not been reached. After confirming the message displayed on the display unit 15, the user performs knock input again.
In this way, the user who transmits the knock determines whether or not the knock has reached the transmission partner.
[0057]
iv) Processing when knock reception is impossible
Here, in the portable terminal that has received the knock, there is a case where it does not make sense to reproduce the knock (for example, when the portable terminal is placed in a bag and the user cannot detect the reproduction knock). Therefore, a knock enabled mode that performs knock playback when a knock arrives and a knock disabled mode that does not perform knock playback are provided on the mobile terminal, and the knock playback mode (knock enabled mode or knock disabled mode) is set by the user's button operation. It can be so.
Here, if a knock arrives while the mobile device is set to the knock invalid mode, the knock is not played or the sound is converted to sound or light instead of playing the knock, Notify the user that a knock is being received. Instead of reproducing the knock, it can be reproduced by converting to sound or light, but of course, it may be used together with the knock reproduction.
However, the fact that there has been a knock incoming call is recorded in the knock incoming call history.
If the knock is not played by leaving a record in the incoming call history, or if the user is not aware of the sound after converting it to sound or light instead of playing the knock. However, the user can confirm that a knock has been received and can return a knock to the knock sender.
[0058]
As described above, the knock reproduction mode can be set by the user's button operation. However, the control unit 12 may grasp the use state and automatically set the knock reproduction mode. For example, the following situation can be considered for determining the knock reproduction mode.
Charging at charging station → Set to knock-disable mode
During a call or button operation → Setting of knock enable mode
Thus, for example, when the mobile terminal is placed on the charging stand for charging, the control unit 12 sets the setting mode of the mobile terminal to the knock invalid mode. If a knock arrives while the mobile terminal is set to the knock invalid mode, the knock is not reproduced, or instead of reproducing the knock, the sound is converted to sound or light and reproduced. Notify that knock is being received. Since the operation of the mobile terminal in the knock invalid mode is the same as that described above (when the knock valid / invalid mode is set by a button operation), the description thereof is omitted.
[0059]
When charging of the portable terminal is completed and the user picks up the portable terminal from the charging stand, the control unit 12 switches from the knock invalid mode to the knock valid mode.
When a knock arrives while the mobile terminal is set to the knock valid mode (for example, when a call is in progress or a button is being operated), the knock is reproduced based on the received data.
In this manner, the control unit 12 may determine whether to reproduce the incoming knock based on the usage status of the mobile terminal, and control the reproduction of the incoming knock. This eliminates the need for the user to operate the button and set the knock playback mode. Therefore, the operation of the mobile terminal is further simplified.
[0060]
Furthermore, a sensor that can sense contact with a human body may be provided in a part of the mobile terminal described above, and the knock reproduction mode may be set based on the output of the sensor.
This sensor is composed of a pressure sensor and a temperature sensor, and the sensor end is exposed on the surface of the portable terminal. The pressure sensor detects whether or not the pressure value is equal to or lower than a predetermined value (for example, pressure when there is nothing in contact with the sensor). Detect whether or not. When it is determined from the detection results of both sensors whether or not a part of the user's body is in contact with the mobile terminal, and the mobile terminal determines that the part of the user's body is not in contact with the mobile terminal In this case, the mobile terminal is set to the knock invalid mode. Since the operation of the mobile terminal 100 when a knock arrives while the knock invalid mode is set is the same as that described above, the description thereof is omitted.
[0061]
In this manner, a sensor that can sense contact with the human body is provided in the portable terminal, and the knock reproduction mode may be set based on the output of the sensor.
[0062]
