Some of these are collectively referred to as portable terminals) having a function of inputting and editing personal information such as schedule data. In a conventional mobile terminal, a user is notified of a predetermined schedule of schedule data stored therein by a voice or by displaying a message on a screen or the like at a start time of the schedule or a predetermined time before the start time. A schedule alarm function is realized. In this case, the mobile terminal compares the current time of a clock provided therein with an alarm start time set in advance for a predetermined schedule in the schedule data. Is notified to the user.

By the way, for example, in consideration of notifying a schedule of attending a meeting in a company, if a user is in a company, it is sufficient to notify the user five minutes before the meeting start time. However, if the user is not at work but at home, it is meaningless to notify the user five minutes before the conference start time. In this case, for example, it is necessary to notify the user one hour before the conference start time.

[0004] However, in the conventional portable terminal, the schedule is not notified in consideration of the place where the user is located, that is, the place where the portable terminal is located.

[0005]

As described above, in the conventional portable terminal, when notifying the schedule, the location where the portable terminal is present is not taken into consideration. However, the schedule is notified according to a preset alarm start time. For this reason, depending on the location where the mobile terminal is present, even if the schedule is notified at a preset alarm start time,
The notice was sometimes meaningless.

Accordingly, an object of the present invention is to provide a mobile terminal and a data notification method capable of appropriately performing data notification according to the location of the mobile terminal.

[0007]

According to the present invention, there is provided a portable terminal for storing schedule data and notifying the schedule data before the start time of the schedule data. Storage means, search means for searching for devices present around the mobile terminal, determination means for determining the location of the mobile terminal from the device detected by the search means, and determination means for determining Setting a notification time of the schedule data stored in the schedule data storage means according to the location of the portable terminal, and notifying the schedule data at the set notification time. Features.

A data notification method according to the present invention includes a schedule data storage means for storing information including a start time with respect to schedule data, and a data notification method for a portable terminal for notifying before the start time of the schedule data. Searching for devices existing around the mobile terminal, determining the location of the mobile terminal based on the device detected as a result of the search, and retrieving the schedule data stored in the schedule data storage means to the mobile terminal. The notification is made at a time corresponding to the location where the information exists.

Thus, it is possible to appropriately perform data notification according to the location where the user exists.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

According to the present invention, a portable terminal such as a portable telephone or a PDA searches for another device such as a PC around the portable terminal, and when the device is detected, the portable terminal is detected by the device. The location is determined, the notification time or the content is changed according to the location, and the schedule data is notified.

For example, a portable terminal is at an office desk,
When a device such as a PC is present near the mobile terminal, the mobile terminal searches for a device present near the device, and determines from the devices detected as a result of the search that the location where the mobile terminal is located is the office. Then, based on the condition that the current time and the place where the mobile terminal is located are offices, the portable terminal notifies schedule data according to the condition. Here, the schedule data “meeting from 10 o'clock” is stored in the mobile terminal, and when the schedule is notified, when the mobile terminal is in the office, the schedule is notified five minutes before the start time. On the other hand, if the mobile terminal is at the user's home, the schedule is notified one hour before the start time. As described above, when the location where the portable terminal is located is different from the location in the schedule, the schedule is notified earlier. In addition,
Notification of schedule data is performed by the mobile terminal and when the mobile terminal notifies the device of the schedule data,
It is assumed that it is performed by the device.

Here, it is assumed that the device search by the portable terminal uses a wireless communication technology of a wireless communication standard called Bluetooth described below. The mobile terminal performs a search for a device by determining whether there is a device with which Bluetooth communication is possible in the vicinity.

(Schedule Notification Operation) Next, a schedule notification operation in the portable terminal 100 will be described.

Here, it is assumed that the registration setting described below is performed in advance on the portable terminal 100. The registration setting means that a plurality of devices (PC30 shown in FIG. 3) that can communicate with each other in Bluetooth
0 is also registered for each device. As device information, Bluetooth
h device name, Bluetooth address, priority,
Search time-out time, attributes, etc. are included, and the mobile terminal 1
00 is stored in the memory 102. Bluetooth
An actual communication partner with the mobile terminal 100 is specified by the device name and the Bluetooth address. The priority defines which device the mobile terminal 100 preferentially searches among a plurality of devices registered in the mobile terminal 100, and the mobile terminal 100 Search in order. The search timeout time is
The upper limit of the time when the mobile terminal 100 continues searching for one device is defined. The attribute is data indicating the location of the device.

The schedule data stored in the portable terminal 100 is in a form having a task, a date, a start time, an end time, an attribute, and the like for each schedule. The mobile terminal 100 stores the schedule data in the memory 102. The attribute of the schedule data is data indicating a place where the schedule is executed, and is, for example, an office (an attribute that specifies a place more than in a company), a company, a home, and the like. Further, data representing the travel time from a location (for example, an office) serving as a base point of the travel is also considered as an attribute.

PDA engine section 200 of portable terminal 100
The schedule program 201 changes the time and contents of the schedule notification from the location where the mobile terminal 100 is determined based on the attribute and the detected device. When transmitting schedule data to the detected device and causing the device to notify the schedule, the schedule program 201 transmits one of a plurality of schedules stored as schedule data, It is possible to transmit a specific range in one schedule (that is, specific data in a task, a date, a start time, an end time, and an attribute).

Next, when the user of the portable terminal operates the PC 300 in the office near the start time of the schedule registered in the portable terminal 100, the portable terminal 100
The operation of the mobile terminal according to the present invention will be described by taking as an example a case where a schedule is transmitted from PC to PC 300 and the schedule is displayed on the screen of PC 300. At this time, the mobile terminal 1
00 may be in the vicinity of the PC 300, and may be in a bag or the like.

FIG. 5 shows a flow of a search operation of another device in the portable terminal 100. Note that this mobile terminal 10
0 search operation, specifically, the CPU of the mobile terminal 100
101 is performed via the wireless module 120 based on the communication program 202. On the other hand, in the PC 300, the communication program 402 performs a communication operation with the portable terminal 100 via the wireless module 320 in accordance with the search operation.

First, the portable terminal 100 searches for other devices existing in the vicinity (step S1). In other words, the mobile terminal 100 uses the Bluetooth registered in the memory 102.
The search is performed in order from the Bluetooth device specified by the other device name and the Bluetooth address, in descending order of priority. B specified by a predetermined Bluetooth device name and Bluetooth address
The search for the Bluetooth device is continuously performed for the set search time-out time, and when the search time-out time elapses, the next highest priority Bluetooth is set.
In order to switch to the search for the et othoth device, the process is once ended (YES in step S2).

On the other hand, when the portable terminal 100 detects a predetermined Bluetooth device within the search timeout period (YES in step S2, YE in step S3).
S), Bluetooth with detected Bluetooth device
An attempt is made to establish an Ethernet connection, and if the connection is successful, a network (piconet) is formed (step S4). For example, the Bluetooth of the PC 300 existing in the office
When the priority of the device name and the Bluetooth address is the second, the portable terminal 100 detects the PC 300 in the second search and forms a network with the PC 300.

Next, the portable terminal 100 detects from the Bluetooth device that has detected and formed a network,
The location where the mobile terminal 100 exists is determined (step S
5). That is, the Bluetooth that formed the network
h device Bluetooth device name or BL
The location where the Bluetooth device is located is determined from the attribute stored corresponding to the Bluetooth address, and the location where the Bluetooth device is located is determined as the location where the portable terminal 100 is located. Bluetooth device that has formed a network is PC3
If it is 00, “office” is stored as an attribute of the PC 300, and the mobile terminal 100 determines that the location where the mobile terminal 100 itself is located is an office based on the attribute. The mobile terminal 100 stores its own location information (office) in the memory 102.

Next, the operation of the portable terminal 100 at the time of schedule notification will be described. In FIG. 6, a schedule is transmitted from the mobile terminal 100 to another device,
The operation when notifying a schedule in another device is shown. Note that the operation of the schedule notification is specifically performed by the CPU 101 of the mobile terminal 100 based on the schedule program 201.

First, the portable terminal 100 acquires a schedule to be notified next (step S11). That is, the portable terminal 100 obtains the current time from the RTC 106.
Then, a schedule whose start time is later than the current time in the schedule data stored in the memory 102 is acquired.

Next, the portable terminal 100 determines by the above-described operation for searching for another device (the operation in FIG. 5) and acquires the position information of the portable terminal 100 itself stored in the memory 102 (step S12). . Then, the portable terminal 100 compares the attribute of the schedule acquired in step S1 with the portable terminal 1.
00, how long before the acquired schedule is notified of the acquired schedule is set based on the own location information (step S13). That is, the mobile terminal 100 compares the attribute of the schedule with the position information of the mobile terminal 100 itself, determines whether or not the two match, and if they match, sets the time of notification of the schedule to the start of the schedule. The predetermined time is set before the time and relatively close.
On the other hand, if the two do not match, the schedule notification time is set to a predetermined time earlier than the case where they match.

The portable terminal 100 is connected to the RTC 106
It is determined whether or not the current time at the time has reached the notification time of the schedule set in step 13 (step S13).
14) In order to notify the schedule when the schedule is reached, the schedule is transmitted to the detected device, and the device is notified of the schedule (step S).
15).

For example, it is assumed that "meeting from 10:00 (attribute: office)" is stored as a schedule, and the current time is 9:30. In this case, since the position information of the mobile terminal 100 itself is “office”, the notification time “9:55” is set so as to notify the schedule at 9:55, which is five minutes before. Then, when the current time has reached 9:55, the portable terminal 100 transmits information on the schedule “meeting (attribute: office) from 10:00” to the PC 300. On the PC 300 side,
The user is notified by displaying the received schedule on the screen of the LCD 303 or the like. Note that P
The notification operation of the schedule in C300 is specifically performed by the CPU 301 based on the communication program 402.

Consider a case where the portable terminal 100 is located at "home". In this case, assuming that another device (for example, a PC) exists around the mobile terminal 100, the mobile terminal 100 searches for the other device and finds that its own location is “home”. Judge. Here RTC1
When the current time obtained from 06 is “8:30”, the mobile terminal 100 notifies the schedule “meeting (attribute: office) from 10:00”, for example, 9:00 which is one hour before. Thus, the notification time “9:00” is set. When the current time reaches 9:00, the mobile terminal 1
00 is set to schedule “10” for another device existing at home.
Information about the meeting (attribute: office) from time to time is transmitted.

If no other device is present around the portable terminal 100 and no other device can be detected, the portable terminal 100 sets the schedule based on the start time of the schedule.
When the current time reaches the start time of the schedule, the notification is made by displaying the schedule on the LCD 103 of the portable terminal 100.

Further, the content of the schedule to be notified may be changed depending on the location where the portable terminal 100 is located. For example, if the location where the mobile terminal 100 is located is “office”, only information on the schedule “meeting from 10:00 (attribute: office)” is displayed. On the other hand, the mobile terminal 1
If the location where “00” is located is “home”, in addition to the information on the schedule “meeting (attribute: office) from 10:00”, a message prompting the user to move to the office is displayed. The time required for movement, a timetable of a train, a bus, or the like may be displayed.

In the above description, the portable terminal 100
Does not notify the schedule, but transmits the schedule to other devices existing in the vicinity, and the other device notifies the schedule.
It is also possible to notify the schedule by itself.

The portable terminal 100 may be able to determine whether the notification of the schedule is made by the portable terminal 100 itself or by another device existing around the portable terminal 100. For example, consider a case where a schedule is notified by screen display. In this case, if the peripheral devices have a large display screen such as a PC, displaying the schedule on the large display screen is easier for the user to understand than displaying the schedule on the mobile terminal 100 having a small display screen. . Also, when a PC is present in the surroundings, it is expected that the user is operating the PC relatively frequently. Therefore, in this case, the portable terminal 100 controls so that the devices existing in the vicinity notify the schedule.

On the other hand, if the schedule notification is set to be performed by voice, the portable terminal 100 itself notifies the schedule.

Further, when the user uses the portable terminal 100, the portable terminal 100 detects it (for example, by detecting the presence or absence of data input), and
The notification of the schedule (screen display or voice) may be performed by itself.

In this manner, the location of the portable terminal itself is determined from other devices existing around the portable terminal,
Since the notification start time of the schedule is set and notified according to the location, it is possible to notify the appropriate schedule according to the location where the user exists.

When the peripheral device is a PC,
Since the schedule is displayed on the large display screen of the PC,
An easy-to-understand schedule can be notified to the user. Further, by displaying the schedule on the display screen of the PC which is likely to be operated by the user, it is possible to increase the possibility of the user seeing the notification of the schedule, and to more reliably notify the user of the schedule. Is possible.

In the above description, the device is P
Although the description has been made assuming that the case is C, the present invention is not limited to this.
Similar to C, home appliances such as a television, a video, a refrigerator, etc., which have a Bluetooth communication function may be used.

Further, it may be possible to set in advance whether the notification of the schedule is performed by the portable terminal or by the devices existing in the vicinity. If the peripheral device is a PC, the process is performed on the PC side, and if the device is a home appliance such as a television, a video, a refrigerator, the process is performed on the portable terminal side. If you want to be notified of the schedule by voice,
The operation may be always performed on the portable terminal side.

In the above description, the case where Bluetooth was used as the communication interface was described. However, the communication interface is not limited to this, and may be of another type. Regardless of radio.

[0053]

As described in detail above, according to the present invention, the location of the portable terminal is determined from the devices existing around the portable terminal, and data notification is performed according to the location. Data notification can be appropriately performed according to the location where the data exists.
