The execution stop instruction is output, and at the same time, the execution stop instruction for the movement information calculation process of the terminal body is output to the movement detection unit 110 (step S5). As a result, positioning of the current position by the GPS processing unit 109 is stopped, and calculation of movement information by the movement detection unit 110 is stopped.

After that, the CPU of the central control unit 101 determines whether or not the remaining charge of the storage battery detected by the remaining charge detector 108a has become 0 (step S6).
Here, when it is determined that the remaining charge of the storage battery is not 0 (step S6; NO), the CPU of the central control unit 101 returns the processing to step S2 and sequentially executes the subsequent processing. .

On the other hand, when it is determined in step S4 that the request instruction for stopping the acquisition of the motion related information has not been received (step S4; NO), the second communication control unit 107 transmits the wrist-type terminal 2 via the wireless PAN. It is determined whether or not the motion-related information acquisition request transmitted by the above is received (step S7).
Here, when it is determined that the instruction requesting the acquisition of the motion related information is received (step S7; YES), the operation control unit 111 executes the positioning process of the current position of the terminal main body to the GPS processing unit 109. The instruction is output, and an instruction to execute the movement information calculation process of the terminal body is output to the movement detection unit 110 (step S8).
Accordingly, the GPS processing unit 109 receives the signal transmitted from the GPS satellite S via the receiving antenna 109a, performs demodulation processing of the GPS signal to generate GPS information, and based on the generated GPS information. By performing a predetermined positioning calculation, the current position (latitude, longitude, altitude) of the terminal body is measured. Further, the movement detection unit 110 identifies the acceleration component of the terminal body from the output of the triaxial acceleration sensor 110a, calculates the step count of the user from the mode of change of the acceleration component, and calculates the calculated step count per predetermined time. Based on this, the amount of movement and the moving speed due to walking are calculated as movement information.

Next, the second communication control unit 107 acquires the position information from the GPS processing unit 109 and the movement information from the movement detection unit 110 as the movement-related information, and acquires the position information and the movement information via the wireless PAN. It is transmitted to the wrist-type terminal 2 (step S9).
When it is determined in step S7 that the request instruction for acquisition of motion-related information has not been received (step S7; NO), the CPU of the central control unit 101 shifts the processing to step S2 in the same manner as above. The process is returned and each subsequent process is executed sequentially.

After that, the CPU of the central control unit 101 shifts the processing to step S6, and determines whether or not the remaining charge level of the storage battery detected by the remaining charge level detector 108a is 0 (step S6).
Here, when it is determined that the remaining charge of the storage battery is not 0 (step S6; NO), the CPU of the central control unit 101 returns the process to step S2, and the subsequent steps in the same manner as above. Let the processes run sequentially.
On the other hand, when it is determined that the remaining charge of the storage battery has become 0 (step S6; NO), the CPU of the central control unit 101 ends the operation control process.

<List-type terminal operation control processing>
Hereinafter, the operation control processing by the wrist type terminal 2 will be described in detail with reference to FIG.
FIG. 5 is a flowchart showing an example of an operation related to the operation control process by the wrist type terminal 2.

  As illustrated in FIG. 5, the communication control unit 205 is communicatively connected to the mobile terminal 1 via a wireless PAN that is realized by a short-range wireless communication standard in which a wirelessly communicable distance is limited to a predetermined distance. (Step S11).

Next, the communication control unit 205 determines whether or not the remaining charge level of the storage battery of the mobile terminal 1 transmitted from the mobile terminal 1 via the wireless PAN is received (step S12).
Here, if it is determined that the remaining charge of the storage battery of the mobile terminal 1 is not received (step S12; NO), the communication control unit 205 causes the remaining charge of the storage battery of the mobile terminal 1 to be retained at predetermined time intervals. The process of determining whether or not the amount has been received is repeatedly executed.

When it is determined in step S12 that the remaining charge of the storage battery of the mobile terminal 1 has been received (step S12; YES), the remaining charge detector 206a of the power supply unit 206 detects the remaining charge of the storage battery ( Step S13). The detected remaining charge amount is output to the memory 202 and temporarily stored in the memory 202. The remaining charge level of the storage battery of the mobile terminal 1 received by the communication control unit 205 is acquired by the remaining charge level acquisition unit 207a.
Subsequently, the comparison unit 207 acquires the remaining charge amount of the storage battery of the wrist-type terminal 2 detected by the remaining charge amount detection unit 206a from the memory 202, and the portable terminal 1 of the mobile terminal 1 acquired by the remaining charge amount acquisition unit 207a. By comparing with the remaining charge of the storage battery, it is determined whether the remaining charge of the storage battery of the mobile terminal 1 is larger than the remaining charge of the storage battery of the wrist-type terminal 2 (step S14).

When it is determined in step S14 that the remaining charge of the storage battery of the mobile terminal 1 is not larger than the remaining charge of the storage battery of the wrist-type terminal 2 (step S14; NO), the operation control unit 210 causes the GPS process to be performed. An instruction to execute the positioning process of the current position of the terminal body is output to the unit 208, and an instruction to execute the movement information calculation process of the terminal body is output to the movement detection unit 209 (step S15).
As a result, the GPS processing unit 208 receives the signal transmitted from the GPS satellite S via the receiving antenna 208a, performs the demodulation process of the GPS signal to generate GPS information, and based on the generated GPS information. By performing a predetermined positioning calculation, the current position (latitude, longitude, altitude) of the terminal body is measured (see FIG. 6B). Further, the movement detection unit 209 specifies the acceleration component of the terminal body from the output of the triaxial acceleration sensor 209a, calculates the step count of the user from the mode of change of the acceleration component, and calculates the calculated step count per predetermined time. Based on this, the amount of movement and the moving speed due to walking are calculated as movement information (see FIG. 6B).

Subsequently, the operation control unit 210 controls the communication control unit 205 to transmit to the mobile terminal 1 a request instruction to stop the acquisition of the motion related information (position information or movement information) (step S16).
After that, the CPU of the central control unit 201 determines whether or not the remaining charge level of the storage battery detected by the remaining charge level detection unit 206a has become 0 (step S17).
Here, when it is determined that the remaining charge of the storage battery is not 0 (step S17; NO), the CPU of the central control unit 201 returns the processing to step S12 and sequentially executes the subsequent processing. .

  On the other hand, when it is determined in step S14 that the remaining charge of the storage battery of the mobile terminal 1 is greater than the remaining charge of the storage battery of the wrist-type terminal 2 (step S14; YES), the operation control unit 210 causes the GPS The execution stop instruction of the positioning process of the current position of the terminal body is output to the processing unit 208, and the execution stop instruction of the movement information calculation process of the terminal body is output to the movement detection unit 209 (step S18). ). As a result, the positioning of the current position by the GPS processing unit 208 is stopped, and the movement information calculation by the movement detection unit 209 is stopped (see FIG. 6A).

Subsequently, the operation control unit 210 controls the communication control unit 205 to transmit a request instruction for acquiring the motion related information (position information or movement information) to the mobile terminal 1 (step S19).
Then, the communication control unit 205 acquires, as the motion-related information, the position information acquired by the GPS processing unit 109 of the mobile terminal 1 and the movement information calculated by the movement detection unit 110 via the wireless PAN (step S20). . That is, when the position information acquired by the GPS processing unit 109 of the mobile terminal 1 and the movement information calculated by the movement detection unit 110 are transmitted from the mobile terminal 1, the communication control unit 205 causes the position to be transmitted via the wireless PAN. Information and movement information are received as motion related information.
After that, the CPU of the central control unit 201 shifts the processing to step S17, and determines whether or not the remaining charge level of the storage battery detected by the remaining charge level detection unit 206a is 0 (step S17).

When it is determined in step S17 that the remaining charge of the storage battery is not 0 (step S17; NO), the CPU of the central control unit 201 returns the process to step S12, and thereafter. The respective processes of are sequentially executed.
On the other hand, when it is determined that the remaining charge of the storage battery is 0 (step S17; NO), the CPU of the central control unit 201 ends the operation control process.

  The movement related information (position information or movement information) acquired by the operation control process is recorded in a predetermined storage means (for example, a recording medium or the like) in association with the current time measured by a timer (not shown).

As described above, according to the information communication system 100 of the first embodiment, the wrist-type terminal 2 is based on the comparison result between the remaining charge of the storage battery of the mobile terminal 1 and the remaining charge of the storage battery of the wrist-type terminal 2. Thus, the acquisition of the first motion related information and the acquisition of the second motion related information can be switched and executed. Specifically, when it is determined that the remaining charge of the storage battery of the mobile terminal 1 is larger than the remaining charge of the storage battery of the wrist-type terminal 2, the GPS processing unit 208 and the movement detection unit 209 acquire the movement-related information. Is stopped and the movement related information (first movement related information) acquired by the mobile terminal 1 is acquired by the communication control unit 205, while the remaining charge of the storage battery of the mobile terminal 1 is equal to that of the storage battery of the wrist-type terminal 2. If it is determined that the amount is not more than the remaining charge, the GPS processing unit 208 or the movement detection unit 209 causes the movement related information (second movement related information) to be acquired. It is possible to favorably save power in consideration of the remaining charge amount of 1.
That is, in a situation where the remaining charge of the storage battery of the mobile terminal 1 is relatively large, it is assumed that the remaining charge of the storage battery of the wrist-type terminal 2 is not sufficient, and the GPS processing unit 208 performs positioning processing and movement detection of the current position. The calculation processing of the movement information such as the movement amount and the movement speed by the unit 209 is stopped, and the position information acquired by the GPS processing unit 109 from the mobile terminal 1 and the movement information calculated by the movement detection unit 110 are used as the movement-related information ( By acquiring the information as the first movement related information), it is possible to relatively reduce the power consumption and save the power of the wrist type terminal 2 itself. On the other hand, in a situation where the remaining charge of the storage battery of the mobile terminal 1 is relatively small, it is assumed that the remaining charge of the storage battery of the wrist-type terminal 2 is sufficient, and the positioning processing by the GPS processing unit 208 and the movement detection unit 209 are performed. By executing the movement information calculation process according to, the wrist-type terminal 2 itself can acquire the movement-related information (second movement-related information).

Further, when it is determined that the remaining charge of the storage battery of the mobile terminal 1 is larger than the remaining charge of the storage battery of the wrist-type terminal 2, the communication control unit 205 acquires the first movement related information from the mobile terminal 1. The position information and movement information can be properly acquired from the mobile terminal 1 as the first motion related information. On the other hand, when it is determined that the remaining charge of the storage battery of the mobile terminal 1 is not greater than the remaining charge of the storage battery of the wrist-type terminal 2, the communication control unit 205 instructs the mobile terminal 1 to perform the first movement-related operation. Since the instruction for requesting the stop of the information acquisition is transmitted, the positioning processing of the current position by the GPS processing unit 109 and the calculation processing of the movement information by the movement detection unit 110 in the mobile terminal 1 can be stopped, and the mobile terminal 1 Power saving can be suitably achieved.
As a result, it is possible to extend the time during which the wrist-type terminal 2 and the portable terminal 1 are connected for information communication so that the power consumption of the entire information communication system 100 can be reduced.

The mobile terminal 1A is connected to the mobile terminal 1A via the mobile terminal 1 so as to be able to communicate (step S38). Subsequently, the operation control unit 210A causes the mobile terminal 1A to transmit a connection request instruction to the server 3 via the wireless PAN by the second communication control unit 214 (step S39).
As a result, the wrist-type terminal 2A enters a state in which it can communicate information with the server 3 via the mobile terminal 1A (step S40). That is, the second communication control unit 214 transmits a request corresponding to an operation signal corresponding to a predetermined operation of the wrist-type terminal 2A by the user to the mobile terminal 1A via the wireless PAN, so that the mobile terminal 1A receives the request. Is transmitted to the server 3 via the communication network N. Further, when the mobile terminal 1A receives the various information transmitted from the server 3, the mobile terminal 1A transmits the various information to the wrist-type terminal 2A via the wireless PAN (see FIG. 12A).

After that, the CPU of the central control unit 201 shifts the processing to step S17 in substantially the same manner as the operation control process of the above-described embodiment, and the remaining charge level of the storage battery detected by the remaining charge level detection unit 206a becomes zero. It is determined whether or not (step S17).
When it is determined in step S17 that the remaining charge of the storage battery is not 0 (step S17; NO), the CPU of the central control unit 201 returns the process to step S12, and thereafter. The respective processes of are sequentially executed.
On the other hand, when it is determined that the remaining charge of the storage battery is 0 (step S17; NO), the CPU of the central control unit 201 ends the operation control process.

  The display control unit 204 of the wrist-type terminal 2A causes the display unit 203 to display various information acquired by the operation control processing.

As described above, according to the information communication system 200 of the second embodiment, the wrist-type terminal 2A is based on the comparison result between the remaining charge of the storage battery of the mobile terminal 1A and the remaining charge of the storage battery of the wrist-type terminal 2. And a process of causing the second communication control unit 214 to acquire various information transmitted from the server 3 without connecting the first communication control unit 213 and the server 3, and the first communication control unit 213. It is possible to switch and execute the processing of connecting the server 3 to the server 3 and acquiring the various information transmitted from the server 3 by the first communication control unit 213. Specifically, when it is determined that the remaining charge of the storage battery of the mobile terminal 1A is larger than the remaining charge of the storage battery of the wrist-type terminal 2, the first communication control unit 213 and the server 3 are not connected. While the various information transmitted from the server 3 is acquired by the second communication control unit 214 via the mobile terminal 1A, the remaining charge of the storage battery of the mobile terminal 1A is lower than the remaining charge of the storage battery of the wrist terminal 2A. If it is determined that the number is not large, the first communication control unit 213 and the server 3 are connected to each other, and various information transmitted from the server 3 is acquired by the first communication control unit 213. Power saving can be suitably achieved in consideration of the remaining amount.
That is, in a situation where the remaining charge of the storage battery of the mobile terminal 1A is relatively large, assuming that the remaining charge of the storage battery of the wrist-type terminal 2A is not sufficient, the first communication control unit 213 and the server 3 are connected. The second communication control unit 214 acquires various information transmitted from the server 3 via the mobile terminal 1A while stopping the power consumption, so that the power consumption of the wrist-type terminal 2A itself is relatively suppressed and the power consumption of the wrist type terminal 2A itself is reduced. Can be realized. On the other hand, in a situation where the remaining charge of the storage battery of the mobile terminal 1A is relatively small, the first communication control unit 213 and the server 3 are connected on the assumption that the remaining charge of the storage battery of the wrist-type terminal 2A is sufficient. Then, various information transmitted from the server 3 can be acquired by the wrist type terminal 2A itself.

When it is determined that the remaining charge of the storage battery of the mobile terminal 1A is larger than the remaining charge of the storage battery of the wrist-type terminal 2, the second communication control unit 214 connects the mobile terminal 1A to the server 3. The mobile terminal 1A can be made to properly acquire various information from the server 3 because the instruction for requesting is transmitted. On the other hand, when it is determined that the remaining charge of the storage battery of the mobile terminal 1A is not greater than the remaining charge of the storage battery of the wrist-type terminal 2A, the second communication control unit 214 sends the server 3 to the mobile terminal 1A. Since the instruction requesting not to be connected is transmitted, it is possible to stop the mobile terminal 1 from acquiring various information from the server 3, and it is possible to appropriately save power in the mobile terminal 1A.
As a result, it is possible to further lengthen the time during which the wrist-type terminal 2A and the mobile terminal 1A are connected so that information communication can be performed, and it is possible to save power in the entire information communication system 200.

The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.

Similarly, in the second embodiment, the functions of the detection unit, the remaining amount acquisition unit, the comparison unit, and the control unit are controlled by the CPU of the central control unit 201 of the wrist-type terminal 2 so that the remaining amount of stored electricity is reduced. Although the configuration is realized by driving the detection unit 206a, the remaining charge amount acquisition unit 207a, the comparison unit 207, and the operation control unit 210A, the present invention is not limited to this, and a predetermined program or the like may be executed by the central control unit 201. The configuration may be realized by being executed.
That is, a program including a detection processing routine, a remaining amount acquisition processing routine, a comparison processing routine, and a control processing routine is stored in a program memory (not shown) that stores the program.
