DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing the configuration of a mobile terminal incorporating the redial device according to the first embodiment of the present invention. The redial device according to the present embodiment is incorporated into a mobile terminal having a packet communication function.
[0027]
As shown in FIG. 1, a mobile terminal 100 incorporating the redial device according to this embodiment includes an antenna 110 that transmits / receives data to / from the network, and transmits or modulates data received via the antenna 110. The modulation unit 120, the control unit 130 for controlling the operation of the redial device, the data storage unit 140 for storing the address book, and the calling unit 150 for generating a voice in response to a signal from the control unit 130 and notifying the user. And an operation unit 160 for the user to input data to the control unit 130, and a display unit 170 for displaying data typed in or received from the operation unit 160.
[0028]
Further, the control unit 130 controls the character call function control unit 131 that controls the character call of the mobile terminal 100 in which the redial device is incorporated, the automatic redial function, and the amount of packets to be communicated at the time of redialing and the redial interval. A redial function setting unit 132 that stores data related to the packet, and a packet amount counter 133 that counts the packet communication amount at the time of redialing.
[0029]
The control unit 130 constitutes a redial device according to the present embodiment.
[0030]
The redial device according to the present embodiment is effective for a mobile terminal device having a packet communication function and capable of text communication (chat).
[0031]
FIG. 2 is a flowchart showing the operation of the mobile terminal 100 incorporating the redial device according to the present embodiment.
[0032]
Hereinafter, with reference to FIG. 2, the operation of the mobile terminal 100 incorporating the redial device according to the present embodiment will be described.
[0033]
First, when the first user 1 starts a character call with the second user, the first user performs a predetermined operation for starting a character call via the operation unit 160.
[0034]
Thereafter, the character call function control unit 131 performs D / A conversion on the transmission data in the modulation unit 120 and then transmits the data to the network side via the antenna 110. That is, a call is made (step A1).
[0035]
Next, the mobile terminal 100 of the first user establishes a packet communication channel with the network via the antenna 110 and establishes a virtual circuit connection (step A2).
[0036]
Next, the mobile terminal 100 of the first user transmits data for logging in to the server and the mail address and other data of the mobile terminal of the second user, and logs in to the server (step A3).
[0037]
After the mobile terminal 100 logs in to the server, the server tries to connect to the mobile terminal of the second user (step A4).
[0038]
Next, the server determines whether or not the second user's mobile terminal is busy, that is, whether or not the second user's mobile terminal is connectable (step A5).
[0039]
The server transmits a notification that it can connect to the mobile terminal of the second user to the first user's mobile terminal 100 via the network (NO in Step A5), and then the mobile terminal 100 of the first user. Is connected to the mobile terminal of the second user (step A9).
[0040]
Next, the network transmits to the first user's mobile terminal 100 that the connection between the first user's mobile terminal 100 and the second user's mobile terminal has been completed.
[0041]
The character call function control unit 131 of the mobile terminal 100 of the first user receives the notification from the network via the antenna 110, and then A / D-converts the data from the modulation unit 120, and calls the call unit 150 and the display unit 170. The first user is notified of the completion of preparation for the start of the text call, and the text call is started (step A10).
[0042]
On the other hand, when the fact that the second user's mobile terminal is in a text call is transmitted from the network to the first user's mobile terminal 100 (YES in step A5), the redial function setting in the control unit 130 is set. The unit 132 is activated and asks the first user whether or not to exercise the automatic redial function via the display unit 170 (step A6).
[0043]
In response to this question, the first user inputs either an answer for setting or not setting the redial function via the operation unit 160.
[0044]
If the first user chooses not to set the redial function (NO in step A6), the character call function control unit 131 transmits a signal for disconnecting the packet communication channel from the antenna 110 to the network, Disconnect the packet communication channel. Thereby, the operation of the mobile terminal 100 of the first user is finished (step A11).
[0045]
When the first user selects to set the redial function (YES in step A6), the character call function control unit 131 keeps the packet communication amount that can be consumed by redialing as the preset packet communication amount. Or ask the first user via the display unit 170 whether to set a new one.
[0046]
In response to this question, the first user selects either a preset packet traffic or a newly set packet traffic. When the newly set packet traffic is selected, a numerical value of the newly set packet traffic is input via the operation unit 160. The amount of packet communication that can be consumed by redialing set in this way is set to n (step A7).
[0047]
Meanwhile, the character call function control unit 131 maintains the packet communication channel established between the first user's mobile terminal and the network without disconnecting.
[0048]
Next, the character call function control unit 131 transmits data for connecting to the mobile terminal of the second user to the server. After receiving the data, the server calls the second user's mobile terminal (step A8).
[0049]
Next, the server determines whether or not the second user's mobile terminal is busy, that is, whether or not the second user's mobile terminal is connectable (step A12).
[0050]
If the response from the server transmitted via the network is connectable to the mobile terminal of the second user (NO in step A12), the server will connect the mobile terminal 100 of the first user and the second user terminal. The user's mobile terminal is connected (step A9), and a character call is started (step A10).
[0051]
On the other hand, if the mobile terminal of the second user is in a character call state (YES in step A12), the character call function control unit 131 determines that the packet communication amount N by redialing counted by the packet amount counter 133 is It is determined whether or not the packet communication amount n set in step A7 is greater than or equal to n (step A13).
[0052]
If the actual packet communication amount N by redialing is smaller than the limit packet communication amount n (N <n), the process returns to step A8 and again tries to connect to the mobile terminal of the second user.
[0053]
When the packet communication amount N is equal to or greater than the limit packet communication amount n (N ≧ n), the redial function setting unit 132 and the character call function control unit 131 display the calling unit 150 and the display. The first user is notified through the unit 170, the established packet communication channel is disconnected, and the series of operations is terminated (step A11).
[0054]
FIG. 3 shows a mobile terminal 100 of a first user, a base station 101 of the mobile terminal 100, a server, a mobile terminal 200 of a second user, a second user when redialing is performed by the redial device according to the present embodiment. 6 is a timing chart showing the progress of the operation of the mobile terminal in the base station 201 in time series.
[0055]
When the mobile terminal 100 of the first user makes a call to the mobile terminal 200 in order to start a text call with the mobile terminal 200 of the second user, the mobile terminal 100 sends a packet communication registration request. A transmission is made to the base station 101 (step 301).
[0056]
Next, the base station 101 sends a packet communication registration response to the mobile terminal 100 (step 302).
[0057]
The mobile terminal 100 that has received the packet communication registration response transmits a virtual line connection request to the base station 101 (step 303), and receives the virtual line connection request from the base station 101 (step 304).
[0058]
As a result, the establishment of the line between the mobile terminal 100 and the base station 101 is completed, and the mobile terminal 100 uses the data for logging into the server, the mail address of the mobile terminal 200 that is the other party for text communication, etc. Transmit to the station 101 (step 305).
[0059]
The base station 101 transmits the received data to the server (step 311), logs in the mobile terminal device 100, and tries to connect to the mobile terminal device 200.
[0060]
However, at this time, since the mobile terminal 200 is in a text call with another party, the server cannot connect the mobile terminal 100 and the mobile terminal 200.
[0061]
The base station 101 that has received notification from the server that the mobile terminal 200 is busy (step 312) notifies the mobile terminal 100 that the mobile terminal 200 is busy (step 306).
[0062]
Here, it is assumed that the first user sets the limit packet communication amount that can be consumed by automatic redial to n.
[0063]
The mobile terminal 100 executes the first redial after setting the packet traffic n (step 307).
[0064]
Here, the base station 101 requests the server again to connect the mobile terminal device 100 and the mobile terminal device 200 (step 313). At this time, the mobile terminal device 200 is still busy. The server receives a notification that the mobile terminal 200 is busy and cannot be connected from the server (step 314).
[0065]
The base station 101 transmits the result to the mobile terminal 100 (step 308).
[0066]
As long as the mobile terminal 200 is busy, this operation (steps 307, 313, 314, 308) is repeated at regular intervals.
[0067]
If the mobile terminal 200 has finished the call before the number of redials within a range where the actual packet traffic N by redial does not exceed the limit packet traffic n (steps 309 and 315), the server In order to connect the mobile terminal device 100 and the mobile terminal device 200, the base station 201 is requested to establish communication with the mobile terminal device 200 (step 321).
[0068]
The base station 201 throws paging to search for the mobile terminal 200 of the second user (step 331).
[0069]
The paged mobile terminal 200 transmits a packet communication registration request to the base station 201 (step 332), and the base station 201 that has received this packet communication registration request transmits a packet communication registration response to the mobile terminal 200. (Step 333).
[0070]
The mobile terminal 200 that has received the packet communication registration response receives the virtual line connection request from the base station 201 (step 334), and then transmits a virtual line connection response to the base station 201 (step 335). Establish.
[0071]
After establishing the line, the base station 201 notifies the server of the completion of connection with the mobile terminal 200 (step 332).
[0072]
Next, the server notifies the base station 101 that the connection with the mobile terminal 200 has been completed (step 316).
[0073]
The mobile terminal device 100 of the first user receives a notification from the base station 101 that the connection with the mobile terminal device 200 is completed (step 310), and then starts a character call with the mobile terminal device 200.
[0074]
FIG. 4 shows the mobile terminal 100 of the first user, the base station 101 of the mobile terminal 100, the server, and the movement of the second user when the packet communication channel is disconnected after redialing by the redial device according to the present embodiment. It is a timing chart which shows the progress of the operation | movement in the base station 201 of the terminal device 200 and the 2nd user's mobile terminal device in time series.
[0075]
In FIG. 4, the same steps as the steps 301 to 308 shown in FIG. 3 are executed. That is, steps 301, 302, 303, 304, 305, 311, 312, 306, 307, 313, 314, 308 in FIG. 3 are steps 401, 402, 403, 404, 405, 421, 422, 406, FIG. 407, 423, 424, and 408, respectively.
[0076]
If the mobile terminal 200 is still busy even after performing M (M is a positive integer) redial within the range where the actual packet communication amount N by redial does not exceed the limit packet communication amount n (step 409, 425, 426, 410), and (M + 1) -th redial, the packet communication amount N reaches the limit packet communication amount n set by the first user or set in advance.
[0077]
The mobile terminal 100 and the base station 101 try to connect to the mobile terminal 200 (steps 411 and 427), but the server notifies the base station 101 that the mobile terminal 200 is in a text call (step 428). ).
[0078]
The base station 101 further transmits a message to that effect to the mobile terminal 100 (step 412).
[0079]
At this point, the mobile terminal 100 has already redialed up to n, which is the limit packet traffic of automatic redialing. Therefore, the mobile terminal 100 transmits a packet communication deregistration request to the base station 101 in order to disconnect the packet communication channel established with the base station 101 (step 413). A packet communication registration cancellation response is transmitted to the terminal device 100 (step 414).
[0080]
As a result, the line is disconnected and the entire process is completed.
[0081]
According to the redial device according to the present embodiment described above, the following effects can be obtained.
[0082]
The first effect is that between mobile terminals having a packet communication function and capable of text calls (chatting), when the other party calling to start a text call is busy, the set packet communication volume is exceeded. The user can redial automatically until the user repeats the call himself / herself, can move to the text call start operation in a simpler operation and in a short time, and can further reduce the communication fee.
[0083]
This is because, when the other party calling to start a character call is busy, the character call function control unit 131 maintains the packet communication channel established for starting the character call without disconnecting it. This is because the automatic redial is performed through the line and the data transmission / reception with the base station 101 required for newly connecting the line can be reduced.
[0084]
In addition, for the user, since the mobile terminal 100 automatically redials, the user only has to set the limit packet communication amount n required for redialing, and simplifies the work of re-calling to start a text call. There is an advantage that can be made.
[0085]
FIG. 5 is a flowchart showing the operation of the mobile terminal incorporating the redial device according to the second embodiment of the present invention.
[0086]
The redial device according to the present embodiment is applied when it is determined that the other party starting the text call is out of service area or the terminal power is turned off before it is determined that the other party is talking.
[0087]
The mobile terminal incorporating the redial device according to the present embodiment has the same configuration as the mobile terminal incorporating the redial device according to the first embodiment shown in FIG.
[0088]
First, steps B1, B2, B3, and B4 similar to steps A1, A2, A3, and A4 shown in FIG. 2 are executed.
[0089]
Next, it is determined whether the mobile terminal of the second user is within a communicable range, out of the communicable range, or powered off (step B5).
[0090]
When the second user's mobile terminal is within the callable range, steps B6, B7, B8, which are the same as steps A5, A6, A7, A8, A9, A10, A11, A12, A13 shown in FIG. B9, B17, B18, B19, B20, and B21 are performed.
[0091]
On the other hand, if the mobile terminal of the second user is out of the callable area or is in a power-off state, the character call function control unit 131 asks the user whether to set redial (step). B10).
[0092]
When redial is not set (NO in step B10), the character call function control unit 131 of the first user's mobile terminal disconnects the packet communication channel established with the network (step B19).
[0093]
When setting redial (YES in step B10), after setting the limit packet communication amount m that can be consumed by redialing (step B11), the mobile terminal of the second user 2 is called (step B12).
[0094]
Next, it is determined whether the second user's mobile terminal is within a callable area, or is outside the callable area or is powered off (step B13).
[0095]
If the mobile terminal of the second user is within the callable range, the process proceeds to step B6 (step B16), and steps after step B6 are performed.
[0096]
Conversely, if the mobile terminal of the second user is out of service area (step B13), the character call function control unit 131 determines whether the packet communication amount M consumed by redial exceeds the limit packet communication amount m. Is determined (step B14).
[0097]
If the packet communication amount M consumed by redial does not exceed the limit packet communication amount m (M <m), the second user's mobile terminal call (step B12) and the second user's mobile terminal call The determination (step B13) as to whether the user is within or outside the possible range is repeatedly executed.
[0098]
If the packet communication amount M consumed by redial is the same as the limit packet communication amount m or exceeds the limit packet communication amount m (M ≧ m), the mobile terminal of the first user has already been established. The packet communication channel being disconnected is disconnected (step B15).
[0099]
Next, the mobile terminal of the first user notifies the first user of the result and ends the series of operations.
[0100]
FIG. 6 shows a mobile terminal 100 of a first user, a base station 101 of the mobile terminal 100, a server, a mobile terminal 200 of a second user, a second user when redialing is performed by the redial device according to the present embodiment. 6 is a timing chart showing the progress of the operation of the mobile terminal in the base station 201 in time series.
[0101]
In FIG. 6, the same steps as the steps 401 to 421 shown in FIG. 4 are executed. That is, steps 601, 602, 603, 604, 605, 621 in FIG. 6 correspond to steps 401, 402, 403, 404, 405, 421 in FIG.
[0102]
Thereafter, the server connects to the base station 201 (step 631) and tries to connect a line between the base station 201 and the mobile terminal 200 in order to connect to the mobile terminal 200.
[0103]
As a result, the base station 201 pages the mobile terminal 200 (step 641). However, since the mobile terminal 200 is out of a callable area or is turned off, no response to the paging is returned. For this reason, the server notifies the base station 101 that the response from the mobile terminal device 200 does not come (step 622), and the base station 101 transmits the same notification to the mobile terminal device 100 (step 606).
[0104]
After receiving this notification, the first user sets the automatic redial limit packet traffic m, performs the first redial, and calls the mobile terminal 200 of the second user (step 607).
[0105]
Steps 623, 632, and 642 similar to steps 321, 631, and 641 are performed. However, since the mobile terminal device 200 is still outside the callable area or is powered off, the response from the mobile terminal device 200 A notification that the message does not come is transmitted from the server to the mobile terminal 100 via the base station 101 (steps 624 and 608).
[0106]
Even if redial is performed for the Lth (L is a positive integer) in the range where the actual packet communication amount M by redial does not exceed the limit packet communication amount m, the mobile terminal 200 is out of the communication range or the power source When it is in an OFF state (steps 609, 625, 633, 642, 624, 608), the packet traffic M is set by the first user by the (L + 1) -th redial, or a limit packet set in advance It is assumed that the communication volume reaches m.
[0107]
The mobile terminal 100 and the base station 101 try to connect to the mobile terminal 200 (steps 611, 627, 634, and 644), but the mobile terminal 200 from the server to the base station 101 is out of a callable area, or power It is notified that the state is OFF (step 628).
[0108]
Next, the base station 101 notifies the mobile terminal device 100 to that effect (step 612).
[0109]
At this point, the mobile terminal 100 has already redialed up to m, which is the limit packet traffic of automatic redial. Therefore, the mobile terminal 100 transmits a packet communication deregistration request to the base station 101 to disconnect the packet communication channel established with the base station 101 (step 613). A packet communication registration cancellation response is transmitted to the terminal 100 (step 614).
[0110]
As a result, the line is disconnected and the entire process is completed.
[0111]
When the redial packet communication amount M does not exceed the limit packet communication amount m (M <m), when the mobile terminal 200 returns from the callable range to the callable range or is turned on, Steps after step 305 shown in FIG. 3 are performed.
