Thus, in the mobile phone 1, the communication cost notification LED 10 is turned on in the "red" lighting color so that the data communication can be executed by the communication method (wide area silent communication method) having a high communication cost. Is made to be recognized by the user.

In step SP4, the control unit 20 determines whether or not the synchronization with the wireless LAN access point 28 is established and the wireless LAN access point 28 can be connected.

If a negative result is obtained here, this means that the wireless LAN access point 28 cannot be connected.
That is, the mobile phone 1 is connected to the wireless LAN access point 2
8 does not exist within the communication range of 8, and at this time the control unit 20 moves to the next step SP6.

On the other hand, if a positive result is obtained in step SP4, this means that the wireless LAN access point 2

As a result, in the mobile phone 1, the communication cost notification LED 10 is turned on in the "yellow" lighting color so that the communication method (wireless LAN) has a low communication cost.
The user can be made aware that the data communication can be executed by the communication method).

In step SP6, the control unit 20 determines whether or not the synchronization has been established with the Bluetooth access point 30 and connection with the Bluetooth access point 30 is possible.

If a negative result is obtained here, this means that connection with the Bluetooth access point 30 cannot be established, that is, that the mobile phone 1 is not within the communication range of the Bluetooth access point 30. At this time, The control unit 20 moves to next step SP8.

At step SP8, the control section 20 determines whether or not the communication cost notification LED 10 is currently turned on in the lighting color of "yellow" or "red".

When a negative result is obtained in step SP8, this means that the communication cost notification LED 10 is not currently lit in the "yellow" or "red" lighting color, that is, the mobile phone 1 is in the wide area wireless base station 26. , The wireless LAN access point 28 and the Bluetooth access point 30 do not exist within the communication range. At this time, the control unit 20 again executes step SP2.

Is made to be able to be recognized.

As described above, the portable telephone 1 causes the communication cost notification LED 10 to gradually light up the lighting color corresponding to the connectable communication system in the order in which the communication cost is required. The communication cost in a possible communication system is made to be gradually recognized by the user from an expensive one to a low one.

(1-3) Communication cost notification processing procedure in the first embodiment Next, a communication cost notification processing for notifying the communication method that requires the least communication cost among the communication methods that can currently perform data communication. The procedure will be described with reference to the flowchart of FIG.

The control unit 20 enters from the start step of routine RT2 and moves to step SP20. Step SP2
At 0, the control unit 20 determines whether or not it is possible to connect to the Bluetooth access point 30.

If a positive result is obtained here, this means that the Bluetooth access point 30 can be connected, or the Bluetooth access point 30 concerned.
This means that the mobile phone 1 has moved into the communication range of (1) and is now ready for connection. At this time, the control unit 20 moves to next step SP21.

At step SP21, the control section 20
By executing the notification LED lighting preparation process described above, if the communication cost notification LED 10 is currently lit in the "blue" lighting color, the communication cost notification LED 10 is continuously lit in the "blue" lighting color, and the Bluetooth access point Three
When it becomes possible to newly connect due to moving into the communication range of 0, for example, the lighting color of "yellow" or "red" which is currently lit on the communication cost notification LED 10 is changed to the lighting color of "blue". Then, the process proceeds to next step SP26.

As a result, in the mobile phone 1, the communication cost notification LED 10 is turned on with the lighting color of "blue" so that the data communication can be executed free of charge at the present time without being aware of the communication method. The user is made to be able to intuitively recognize a certain thing through visual sense.

On the other hand, if a negative result is obtained in step SP20, this means that the data is not connected to the Bluetooth access point 30 and the data communication cannot be performed free of charge according to the Bluetooth communication method. This means that the control unit 20 moves to the next step SP22.

At step SP22, the control section 20
It is determined whether the wireless LAN access point 28 can be connected.

If a positive result is obtained here, this means that the wireless LAN access point 28 can be connected, that is, there is no mobile phone within the communication range of the Bluetooth access point 30, and the wireless LAN access point 28 within the communication range, and at this time the control unit 20 proceeds to the next step SP.
Move to 23.

At step SP23, the control section 20
For example, when the communication cost notification LED 10 is currently lit in the "yellow" lighting color, the communication cost notification LED 10 is continuously lit in the "yellow" lighting color, and the communication cost notification LED 10 is "blue".
Alternatively, when the lighting color is "red", the lighting color is changed to "yellow" and the process proceeds to the next step SP26.

As a result, in the mobile phone 1, by turning on the communication cost notification LED 10 in the "yellow" lighting color, it is possible to carry out data communication at a low communication cost at this point without being aware of the communication system. It is designed so that the user can visually and intuitively recognize it.

On the other hand, if a negative result is obtained in step SP22, this means that the wireless LAN access point 28 is not connected and the data communication cannot be executed at a low communication cost according to the wireless LAN communication system. At this time, the control unit 20 performs the next step SP24.
Move to.

At step SP24, the control section 20
It is determined whether the wide area wireless base station 26 can be connected.

When a positive result is obtained here, this means that only the wide area wireless base station 26 can be connected, that is, the mobile phone is within the communication range of the Bluetooth access point 30 and the wireless LAN access point 28. It does not exist, which means that it exists only within the communication range of the wide area wireless base station 26. At this time, the control unit 20 moves to next step SP25.

At step SP25, the control section 20
For example, when the communication cost notification LED 10 is currently lit in the "red" lighting color, the "red" lighting color is continuously lit, and the communication cost notification LED 10 is lit in the "blue" or "yellow" lighting color. If so, the lighting color is changed to "red" and the process proceeds to the next step SP26.

As a result, the mobile phone 1 can be connected only to the wide area wireless base station 26 at the present time, and the data communication is executed at the highest communication cost according to the wide area wireless communication system. 20 moves to the next step SP25.

As a result, in the mobile phone 1, the communication cost notification LED 10 is turned on in the "red" lighting color to enable data communication requiring a high communication cost at the present time without being aware of the communication method. Is made to be intuitively perceptible to the user.

On the other hand, if a negative result is obtained in step SP24, this means that this is not connected to any of the Bluetooth access point 30, the wireless LAN access point 28, and the wide area wireless base station 26, and the data communication is currently performed. In this case, the control unit 20 returns to step SP20 again, and repeats the above-described processing until connection with any of the Bluetooth access point 30, the wireless LAN access point 28 or the wide area wireless base station 26 becomes possible. .

That is, in the mobile phone 1, if the data communication can be executed by the Bluetooth communication method having the highest priority, the communication cost notification LED 10 is first turned on with the lighting color of "blue". Then, the data communication cannot be executed by the Bluetooth communication method, but if the data communication can be executed by the wireless LAN communication method, the communication cost notification LED 1 is displayed in a lighting color of “yellow”.
0 is turned on.

Therefore, the mobile phone 1 sends the communication cost notification L
Based on the lighting color to be turned on by the ED 10, the user can be notified in real time of the communication method desired by the user that requires the least communication cost.

At step SP26, the control section 20
A predetermined communication method automatic selection button provided on the operation unit 5 is pressed to automatically select a communication method corresponding to the lighting color of the communication cost notification LED 10 and start a data communication. Is given.

When a negative result is obtained here, this means that the automatic selection communication start command has not been given, and at this time the control unit 20 returns to step SP20 and repeats the above-described processing.

On the other hand, when a positive result is obtained in step SP26, this means that the user has pressed the communication system automatic selection button to give the automatic selection communication start command, and at this time, the control unit. 20 moves to the next step SP27.

At step SP27, the control section 20
Step SP21, step SP23 or step SP
The data communication is started by the communication method corresponding to the lighting color when the communication cost notification LED 10 is turned on by any one of 25 (here, for example, the Bluetooth communication method corresponding to "blue"), and the process proceeds to the next step SP28.

As a result, the mobile phone 1 automatically selects the Bluetooth communication method which requires the least communication cost at the present time by simply pressing the communication method automatic selection button without causing the user to perform a complicated operation, and the Bluetooth communication concerned. The data communication can be performed by a method.

At step SP28, the control section 20
It is determined whether or not a communication end command for ending the data communication is given via the operation unit 5, and the process waits until the communication end command is given.

On the other hand, when an affirmative result is obtained in step SP28, this means that the communication end command has been given, and at this time the control unit 20 proceeds to the next step S.
The procedure moves to P29, and the communication cost notification processing procedure described above ends.

Then, the control unit 110 executes the condition information allocation program to cause the wide area wireless communication processing unit 11 to execute.
1, the communication cost lighting color table T500A, the communication speed lighting color table T500B, and the connection degree lighting color table T5 based on the respective condition information acquired from the wireless LAN communication processing unit 112 and the Bluetooth communication processing unit 113.
00C is used to assign a lighting color to each communication method.

That is, the control unit 110 assigns the lighting color to the communication cost, the communication speed, and the connection degree based on the respective condition information received from each access destination, so that each communication system as shown in FIG. An allocation table T600 in which a lighting color is allocated for each is generated, and this can be stored in the RAM (not shown) of the control unit 110.

For example, Bluetooth access point 1

Data, wireless LAN speed data indicating that the maximum communication speed is 11 [Mbit / sec] (that is, high communication speed), and one wireless LAN access point 115.
The communication range that can be covered by the wide area wireless base station 114
Since the wireless LAN connection degree is narrower than that of the Bluetooth access point 116 and narrower than that of the Bluetooth access point 116, the degree of connection is weaker than that of the wide area wireless communication method and is stronger than that of the Bluetooth communication method. Data and are included.

As a result, the allocation table T600 of the wireless LAN communication system generated based on the wireless LAN condition information.
"Yellow" for the communication cost notification LED 101A, "blue" for the communication speed notification LED 101B,
"Yellow" is stored in association with each of the connection degree notification LEDs 101C.

Wide area connectivity data indicating that the degree of connection is strong because the communication range covered by the wireless base station 26 is wide is included.

As a result, in the wide area wireless communication system allocation table T600 generated based on the wide area condition information, the communication cost notification LED 101A is "red", the communication speed notification LED 101B is "red", and the connection degree is Notification L
“Blue” is associated and stored with the ED 101C.

Incidentally, in the portable telephone 100, the allocation table is set in accordance with the lighting color table T500 each time the conditions (communication cost, communication speed, and degree of connection) related to the communication connection of each communication method are received as condition information from each access destination. T600 can be sequentially updated.

Here, in the mobile phone 100, a communication mode in which the communication cost is the most important and the user is informed of the communication method advantageous to the user through the communication cost notification LED 101A, and the communication mode in which the communication cost is the most important condition, and the communication mode The communication speed priority mode in which the communication speed is the most important condition so that the communication method having the highest speed and advantageous to the user is notified via the communication speed notification LED 101B, and the communication method having the strongest connection degree and advantageous to the user are connected. Degree notification LED
It has a connectivity priority mode in which the connectivity is the most important condition as notified via 101C.

Then, in the mobile phone 100, the user selects the cost-oriented mode, the communication speed-oriented mode, or the connection-oriented mode via the operation unit 5 as the selection means, and the communication cost is calculated based on the above-mentioned allocation table T600. Notification LED 101A, communication speed notification LED 101
B and the connection degree notification LED 101C are each turned on with a predetermined lighting color.

(2-2) Connection Condition Notification Processing Procedure in Second Embodiment Next, based on the selection of the cost-oriented mode, the communication speed-oriented mode or the connection degree-oriented mode, the most advantageous and excellent condition for the user is set. A condition notification processing procedure for notifying the communication method of the user will be described with reference to the flowchart shown in FIG.

The control section 110 enters from the start step of routine RT3 and moves to step SP40. Step S
In P40, control unit 110 determines whether or not the condition information for the predetermined communication method has been received.

When a negative result is obtained here, this means that the condition information for the predetermined communication system has not been received, that is, synchronization by the wide area wireless communication system, the wireless LAN communication system or the Bluetooth communication system has been established. This means that the data communication cannot be executed at this moment, and at this time, the control unit 110 waits until any condition information is received.

On the other hand, when an affirmative result is obtained in step SP40, this means that the condition information for the predetermined communication system has been received, that is, the synchronization by the wide area wireless communication system, the wireless LAN communication system or the Bluetooth communication system is at least obtained. One of them is established and indicates that the data communication can be executed according to any one of the communication methods at this moment, and at this time, the control unit 110 moves to the next step SP41.

At step SP41, the controller 110
Is an allocation table T600 (FIG. 9) according to the lighting color table T500 for each condition information received in step SP40.
Is generated and stored in RAM, and the next step S
Move to P42.

At step SP42, the controller 110
Determines whether the cost-oriented mode has been selected.

If an affirmative result is obtained here, this means that the cost-oriented mode in which the communication cost is the most important condition is selected, that is, the communication cost is currently the highest among the communication methods capable of executing data communication. This indicates that the user wants to recognize an advantageous communication method that is unnecessary, and at this time, the control unit 110 causes the control unit 110 to perform the next step SP4.
Move to 3.

At step SP43, the controller 110
Is, for example, BT condition information and wireless LA in step SP40.
When the N condition information and the wide area condition information are received and the data communication can be executed according to the Bluetooth communication method, the wireless LAN communication method and the wide area wireless communication method, the communication cost is the highest based on the allocation table T600 (FIG. 9). A free Bluetooth communication method that is advantageous to the user (the communication cost is the lowest) is selected, and the process proceeds to the next step SP44.

At step SP44, the controller 110
Displays the lighting color assigned to the Bluetooth communication method selected in step SP43 to the communication cost notification LED
101A, the communication speed notification LED 101B, and the connection degree notification LED 101C are turned on respectively, and the next step SP
Move to 48.

As a result, the mobile phone 100 turns on "blue" assigned to the communication cost of the Bluetooth communication method to the communication cost notification LED 101A so that the communication cost is the most important at the present time without being aware of the communication method. The user is made aware that advantageous data communication is possible.

At this time, in the mobile phone 100, the communication speed notification LED 101B lights up "yellow" assigned to the communication speed of the Bluetooth communication system, so that the communication speed is neither high nor low. The user is made to simultaneously recognize that data communication can be executed at a speed, and "red" assigned to the connection degree of the Bluetooth communication method is turned on by the connection degree notification LED 101C. At the same time, the user is made to recognize that the degree of connection is weak.

That is, the mobile phone 100 allows the user to recognize the superiority or inferiority of the communication cost, which the user attaches most importance to, based on the lighting color of the communication cost notification LED 101A.
Communication speed notification LED 101B and connection degree notification LED 10
The superiority or inferiority of the communication speed and the degree of connection can be simultaneously recognized in an auxiliary manner based on the lighting color of each of the 1C lights.

As a result, the mobile phone 100 is superior in the Bluetooth communication system when the user desires to download contents having a certain amount of data such as a simple home page without requiring communication costs. Thus, it is possible to visually and intuitively recognize that the data communication can be executed under the best condition at the present time.

Incidentally, for example, when the BT condition information has not been received at the present time and the data communication cannot be executed according to the Bluetooth communication method, the wireless LAN which does not require the next communication cost according to the priority order of the allocation table T600 in step SP43. Select communication method, step SP4
The lighting color assigned to the wireless LAN communication method in 4 indicates the communication cost notification LED 101A and the communication speed notification LED 1
01B and the connection degree notification LED 101C are turned on respectively.

On the other hand, when a negative result is obtained in step SP42, this means that the cost-oriented mode has not been selected, that is, the communication method having the highest communication speed among the communication methods capable of executing data communication at the present time or This means that the user wants to recognize one of the communication methods with the highest degree of connection. At this time, the control unit 11
If 0, the process proceeds to next step SP45.

At step SP45, the controller 110
Determines whether or not the communication speed priority mode is selected.

If a positive result is obtained here, this means that the communication speed priority mode in which the communication speed is the most important condition is selected, that is, the communication speed is the most important among the communication methods capable of executing data communication. , Which indicates that the user wants to recognize the communication method with the best communication speed (the highest communication speed) at this moment, and at this time, the control unit 110 moves to the next step SP46.

At step SP46, the controller 110
For example, when the Bluetooth condition information, the wireless LAN condition information and the wide area condition information are received in step SP40 and the data communication can be executed according to the Bluetooth communication method, the wireless LAN communication method and the wide area wireless communication method, the allocation table T600 (see FIG. Based on 9), the wireless LAN communication method which is most advantageous for the user and has the highest communication speed is selected, and the process proceeds to the next step SP44.

At step SP44, the controller 110
Displays the lighting color assigned to the wireless LAN communication method selected in step SP46 to the communication cost notification LED 10
1A, communication speed notification LED 101B, and connection degree notification LE
D101C is turned on respectively, and the next step SP48.
Move to.

Thus, the portable telephone 100 turns on the communication speed notification LED 101B in the "blue" lighting color, so that the communication speed is the highest at the present time and data communication can be executed at high speed without being aware of the communication method. The user can be made aware of this.

At this time, the portable telephone 100 can simultaneously let the user recognize that the data communication can be executed at a low communication cost by turning on the communication cost notification LED 101A in the "yellow" lighting color. ,
By lighting the connection degree notification LED 101C in the "yellow" lighting color, the user can be made to simultaneously recognize that the connection degree is medium.

As a result, the portable telephone 100 can use the wireless LAN communication in the case where the user desires to download the contents of large-capacity data that requires real-time processing such as moving image distribution and music distribution. The method is excellent, and is thus made to visually and intuitively recognize that the data communication can be performed under the best condition at the present time.

On the other hand, if a negative result is obtained in step SP45, this means that the communication speed priority mode is not selected.
The connection degree priority mode, in which the connection degree is the most important condition, has been selected, that is, among the communication methods that can perform data communication, the connection degree is the most important and the connection degree is the best at the moment (the connection degree is the most important). This indicates that the user wants to recognize the (strong) communication method, and at this time, the control unit 110
Moves to the next step SP47.

At step SP47, the controller 110
Is, for example, BT condition information and wireless LA in step SP40.
When the N condition information and the wide area condition information are received and the data communication can be executed according to the Bluetooth communication method, the wireless LAN communication method, and the wide area wireless communication method, the connection degree is strongest based on the allocation table T600 (FIG. 9). A wide area wireless communication method advantageous for the user is selected, and the process proceeds to the next step SP44.

At step SP44, the controller 110
Displays the lighting color assigned to the wide area wireless communication system selected in step SP47 to the communication cost notification LED 101.
A, communication speed notification LED 101B and connection degree notification LED
Each of them lights up at 101C, and the process proceeds to the next step SP48.

Thus, the cellular phone 100 turns on the connection degree notification LED 101C in the "blue" lighting color, and informs the user that the data communication can be maintained even when the connection degree is strong and the user is moving without being aware of the communication method. It is designed to be recognized.

At this time, in the mobile phone 100, the communication cost notification LED 101A is turned on in the "red" lighting color so that the user can simultaneously recognize that data communication can be executed at a high communication cost. The communication speed notification LED 101B is turned on in a "red" lighting color so that the user can simultaneously recognize that the communication speed is low.

As a result, the cellular phone 100 is the best in the wide area wireless communication system because the data communication is less likely to be disconnected when it takes time such as downloading moving images while moving at high speed. Thus, it is possible to visually and intuitively recognize that the data communication can be executed under the best condition at the present time.

At step SP48, the controller 110
When a predetermined communication system automatic selection button (not shown) provided on the operation unit 5 is pressed, the communication cost notification LED 1
01A, communication speed notification LED 101B and connection degree notification L
A communication method corresponding to the lighting color of the ED 101C is automatically selected, and it is determined whether or not an automatic selection communication start command for starting data communication is given.

If a positive result is obtained in step SP48, this means that the communication system automatic selection button has been pressed and an automatic selection communication start command has been given, that is, the cost-oriented mode has been selected in step SP42, At SP44, the lighting color corresponding to the Bluetooth communication method is the communication cost notification LED 101A and the communication speed notification L
When the ED 101B and the connection degree notification LED 101C are lit, the user recognizes that the auxiliary communication speed and the connection degree are advantageous conditions in addition to the communication cost of the Bluetooth communication method, and the Bluetooth communication method is selected. This means that the selection is decided. At this time, the control unit 110 moves to the next step SP50.

On the other hand, when a negative result is obtained in step SP48, this means that the communication system automatic selection button is not pressed and the automatic selection communication start command is not given, that is, the cost priority mode is selected. In the Bluetooth communication system, the most important communication cost is free, but it is hard to say that the auxiliary communication speed or connection degree is an advantageous condition for the user. This means that the change command is given because the user desires to recognize the condition (here, the wireless LAN communication method in which the communication cost is low), and at this time, the control unit 110 moves to the next step SP49.

At step SP49, the controller 110
Selects the wireless LAN communication system with the second highest priority set next to the Bluetooth communication system in the cost-oriented mode based on the allocation table T600 (FIG. 9), returns to step SP44 again, and is assigned to the wireless LAN communication system. The lighting color indicates the communication cost notification LED 101A, the communication speed notification LED 101B, and the connection degree notification LED 101C.
Light up.

As described above, the control section 110 has the step SP.
By sequentially repeating step SP49 and step SP44 until a positive result is obtained at 48, the communication cost notification LED 101A, the communication speed notification LED 101B, and the connection degree notification LED 101C are lit with the lighting colors corresponding to the communication methods in descending order of priority. It is designed to do.

As a result, the mobile phone 100 allows the user to recognize the superiority or inferiority of the connection condition of the highest importance and the superiority or inferiority of other conditions at the same time, so that the communication system which is in the most advantageous condition for the user as a whole can be obtained. You have a choice.

When the communication speed priority mode is selected in step SP45, the communication methods are sequentially selected according to the priority set for the communication speed in accordance with the allocation table T600 in step SP49, and the selection is made in step SP44. The lighting color assigned to the selected communication method is turned on to the communication cost notification LED 101A, the communication speed notification LED 101B, and the connection degree notification LED 101C.

When the connection importance mode is selected in step SP45, the communication system is sequentially selected according to the priority set for the connection according to the allocation table T600 in step SP49, and the SP is selected.
The lighting color assigned to the selected communication method at 44 is the communication cost notification LED 101A and the communication speed notification LE.
The D101B and the connection degree notification LED 101C are turned on.

At step SP50, the controller 110
Indicates, for example, a communication cost notification LED 101 with a lighting color corresponding to the Bluetooth communication method in the cost-oriented mode.
A, communication speed notification LED 101B and connection degree notification LED
When the light is turned on in 101C, data communication is executed by the Bluetooth communication method, and the next step SP5
The process moves to 1 and waits until the communication end command of the data communication is given.

If a positive result is obtained in step SP51, this means that a communication end command for data communication has been given, and at this time the control unit 110 moves to the next step SP52 and makes a connection condition notification process. Finish the procedure.

(2-3) Operation and Effect of Second Embodiment In the above configuration, when the mobile phone 100 receives the condition of the communication method from the access destination as the condition information, it receives the condition according to the lighting color table T500. Allocation table T6 in which the lighting color is allocated for each communication method based on the condition information
00 is generated.

Then, in the portable telephone 100, based on the most important condition corresponding to the cost-oriented mode, the communication speed-oriented mode or the connection degree-oriented mode selected by the user,
At the present time, a communication method having the most advantageous and excellent conditions for the user is selected, and the lighting color assigned to the selected communication method is turned on to the communication cost notification LED 101A, the communication speed notification LED 101B, and the connection degree notification LED 101C, respectively.

Therefore, in the mobile phone 100, the communication cost notification LE is displayed in the lighting color assigned to the selected communication method.
D101A, the communication speed notification LED 101B, and the connection degree notification LED 101C are turned on to allow the user to recognize the superiority or inferiority of the most important condition that is most emphasized by the user, and also to simultaneously supplementarily recognize the superiority or inferiority of other conditions of the communication system. Even if the user does not know in advance the superiority or inferiority of the conditions that the communication method has, in addition to the superiority or inferiority of the main priority condition that does not make the user aware of the communication method, the superiority or inferiority of other auxiliary conditions. Accordingly, it can be determined whether or not to execute the data communication.

In the mobile telephone 100, the most important condition is the best, but when the other conditions are not excellent and the condition is not advantageous to the user as a whole, the change command gives the most important condition. The communication system having the next highest priority is selected according to the allocation table T600, and the lighting color associated with the selected communication system is notified of the communication cost L
The ED 101A, the communication speed notification LED 101B, and the connection degree notification LED 101C are turned on.

Therefore, in the mobile phone 100, in addition to the most important condition, the merits and demerits of other conditions are recognized at the same time.
