The PDC / P constructed as described above
By subscribing to a mobile phone (PDC) service, the HS complex type mobile phone is given a mobile phone number, and information necessary for connection is stored in the EEPROM 18,
Accordingly, actual communication via a PDC wireless base station (hereinafter, this communication method is referred to as “mobile”) has become possible, and by subscribing to a PHS public network service, a PHS telephone A number is given, and information necessary for connection is stored in the EEPROM 18, so that actual communication via the PHS radio base station (hereinafter, this communication method is referred to as "PHS") is enabled. By registering with the private PHS exchange, the extension number is given and the information necessary for connection is EEPRO.
M18, so that actual communication via the private PHS exchange (hereinafter, this communication method is referred to as “OS (office station)”) is enabled. The extension number is given by registering with the handset, and information necessary for connection is stored in the EEPROM 18, and accordingly, actual communication via the digital cordless telephone base unit (hereinafter, this communication method is referred to as "HS (Home) Station) ”).

In the "PHS", in addition to the above, P
There is also a communication system that enables the use of “PHS” inside a room through a home antenna having a repeater function installed indoors in the service area of the HS radio base station. Description is omitted.

Hereinafter, the PDC / P constructed as described above will be described.
First, the operation of the "mobile phone" of the HS complex type mobile phone will be described by dividing the operation into "standby", "incoming call", "communication", and "outgoing call".

[Standby] When the power is turned on, the microcomputer 12 reads a subscriber number (MSN), a mobile station number (MSI), a perch channel number and the like from the EEPROM 18, and measures reception levels of frequencies corresponding to all perch channel numbers. , A table is created in the order of the reception level, and the storage unit 1
7 is stored in the RAM. Then, first, the frequency is switched to the highest level, synchronization is established by the channel codec of the PDC baseband unit 4 and the microcomputer 12 (frame synchronization and superframe synchronization), and the broadcast information from the base station is transmitted to the microcomputer 12. Reads and checks the standby conditions and the like, and shifts to the standby channel specified by the broadcast information.

When the synchronization is not achieved or when the standby condition is not satisfied, the frequency is switched to the next frequency based on the level order table stored in the RAM of the storage unit 17, and the above operation is repeated.

During standby, the channel codec of the PDC baseband unit 4 intermittently receives the PCH (paging channel) on the common control channel, and during standby, it is instructed by its own station and the broadcast information. The electric field strength of the peripheral channel is intermittently measured by the receiving means of the PDCRF unit 3.

[Incoming Call] The PDC radio base station transmits incoming call information on the PCH to the calling mobile station. The mobile station receives the incoming information on the PCH every time by the channel codec of the PDC baseband unit 4, and the microcomputer 12
As a result of the information analysis, if the incoming information is addressed to the own station, the microcomputer 12 controls the voice codec 7 to output a ring tone to the buzzer 11 or vibrate the vibrator 15 and blink the incoming LED 14.

At this time, a radio status report including the field strengths of the local station and peripheral channels is transmitted to the PDC radio base station, and the microcomputer 12 thereafter transmits the PDC signal to the PDC baseband unit 4 via the channel codec. By exchanging messages with the radio base station, a communication channel is set in accordance with the digital car telephone system standard.

[Communication] In the communication channel, either voice communication or data communication is performed. In the case of voice communication, reception is performed by the antenna 1 or 2.
(Switching by diversity) and receive PDC
A signal from the RF unit 3 is output to the receiver 8 or the earphone microphone jack 10 via the PDC baseband unit 4 and the audio codec 7, and the audio input from the microphone 9 or the earphone microphone jack 10 is output to the audio codec 7 and the PDC. Baseband unit 4 and PDCRF unit 3
Is transmitted as a radio wave from the antenna 2 via the.

On the other hand, in data communication, radio waves are transmitted and received in the same manner as in the voice communication described above.
A signal from the C baseband unit 4 is output to an external interface connector via an interface circuit (not shown), and data communication is performed by an external device connected to the external interface connector.

[Originating] While the mobile station is waiting, the input unit 1
When the transmission operation is performed by the key operation or the like of 6, the microcomputer 12 creates a message including the other party number and the peripheral electric field strength, and transmits the message from the antenna 2 through the channel codec of the PDC baseband unit 4 and the PDCRF unit 3. P
While transmitting to the DC radio base station,
Exchanges messages with the PDC wireless base station via the channel codec of the PDC baseband unit 4, thereby setting a communication channel in accordance with the digital mobile phone system standard.

The above is the operation of the “mobile”, and then the “P”
The operation of the “HS” will be described separately for “standby (intermittent reception)”, “incoming call”, and “outgoing call”. Note that the [communication] is the same as the above-described "mobile" operation, and therefore will not be described. Also, the mobile station is set to “PS” so as not to be confused with the operation of the “mobile” described above.
(Personal Station), base station "CS" (Cell Stati
on) will be described below.

[Standby (intermittent reception)] When the power is turned on, the microcomputer 12 reads the CS-ID from the EEPROM 18
(CS identification code) and PS-ID (PS identification code) are read and supplied to the PHS baseband unit 6, and then the PHS
The baseband unit 6 receives, via the antenna 2 and the PHSRF unit 5, the broadcast channel on which the CS is performing intermittent transmission, and the CS-I in the received broadcast channel.
The microcomputer 12 compares D with the CS-ID read from the EEPROM 18, and when the CS-ID matches, the PS validates the information in the broadcast channel.

Similarly, the paging channel on which the CS is performing intermittent transmission is also received. When the CS-IDs are compared with each other, the information of this channel is validated and the operation proceeds to the intermittent reception operation. During the intermittent reception operation, the intensity of the radio wave coming from the CS is measured by the receiving means of the PHSRF unit 5.

[Incoming Call] In the intermittent transmission of the CS, if there is an incoming call during the intermittent reception of the PS, the CS transmits the incoming call information to the paging channel to notify the incoming call to the PS (similar to the intermittent transmission). Steps). When the PS receives the paging channel containing the incoming call information, the microcomputer 12 controls the voice codec 7 to output a ring tone to the buzzer 11 or vibrates the vibrator 15 and blinks the incoming call LED 14 to ring the incoming call. After that, the connection confirmation information is returned to the CS through the dedicated cell channel.

[Transmission] In the intermittent transmission of the CS, when the transmission operation is performed by the key operation of the input unit 16 of the PS during the intermittent reception of the PS, the microcomputer 12 causes the baseband unit 6 and the PH to operate.
Using the SRF unit 5, the control carrier transmits a link channel establishment request to the CS using the dedicated cell channel. Then, the CS receiving this performs, for example, carrier sense of a communication carrier selected at random, and returns a link channel assignment with a control carrier to the PS if the slot of the carrier is not used, and switches to the assigned carrier. Wait for a sync burst.

On the other hand, the PS that has received the link channel assignment switches to the assigned communication carrier, performs carrier sensing, and then transmits a synchronization burst, and thereafter transmits the communication channel according to the second generation digital cordless telephone system standard. Set.

The above is the operation of the “PHS”, and the “OS”
The detailed description of the operation of “HS” and “HS” is omitted, and the operation when displaying an available communication method will be described based on the flowchart shown in FIG. 3 and the explanatory diagrams shown in FIGS. I do.

It is assumed that the storage unit 17 stores a communication system with the highest priority and parameters of each communication system.
Among these, as shown in FIG. 4 (a), the highest-priority communication methods are the items of “number of the highest-priority communication method” and “number of the highest-priority communication method of the PHS group” representing the highest-priority communication method. The parameters of each communication method are shown in FIG.
As shown in (b), the "number" of each communication method, the "communication method" representing the actual communication method, the "number of the next-priority communication method" representing the next communication method to be shifted, and the like. “Group type” indicating which group the communication method belongs to, “selection” indicating the selected communication method, “display element (when not selected)” indicating a display element when not selected, and display element when selected. "Display element (when selected)", "usability" indicating whether the communication method is registered and usable, and "usability (service) indicating whether the communication method is currently serviceable. Yes / No) ”.

The “number of the highest-priority communication method”, “number of the highest-priority communication method of the PHS group”, and “number of the next-priority communication method” are PDCRF units 3 and P.
The setting is automatically performed by detection of out-of-service area / in-service area based on the reception electric field strength and synchronization detected and output by the reception unit of the HSRF unit 5, or is manually set by an operation of the input unit 16 by a user. First,
As shown in FIGS. 5A and 5B, an example of the priority of the group type is displayed on the display unit 13 so as to be selected, and then, FIGS. 5C and 5D. As shown in
It is preferable to display an example of the priority order within the group on the display unit 13 so that the user can select the priority order. Note that this priority is determined by the order of selection of the communication method to be used when making a telephone call, the order of selection of the communication method to be selected as the display target of the radio field intensity level, the order of switching the communication method by pressing the mode button, and the like. This is used as a communication system selection order when automatic transmission is performed by automatically switching to another communication system when transmission fails.

The “usability” is set by data stored in the EEPROM 17, and the “usability (service availability)” is determined by the reception electric field strength detected and output by the receiving means of the PDCRF unit 3 and the PHSRF unit 5. Out-of-service / in-service detection based on
The “usability” is updated each time a new communication system is registered in the EEPROM 17, and the “usability (service availability)” is periodically updated by intermittent reception in the “standby” operation.

In the state where the highest priority communication method and the parameters of each communication method are stored in the storage unit 17 as described above, the first display such as at power-on or at the end of communication is performed. First, the communication system with the highest priority stored in the storage unit 17 is selected in the parameters of each communication system stored in the storage unit 17 (step S
1) That is, "●" is moved to the item of "selection" in the parameter of the communication system with the highest priority, the display on the display unit 13 is cleared (step S2), and the highest priority stored in the storage unit 17 is stored. The communication method is processed (step S
3).

Then, the parameters of the communication method to be processed are acquired from the storage unit 17 (step S4), and it is determined whether the service is selected or not (steps S5 and S6). When it is determined that the selected item is selected, the display element of the selected display is displayed on the display unit 13.
Are displayed left-justified (step S7), and when it is determined that the service is being performed and not selected, the display element of the non-selected display is displayed left-justified on the display unit 13 (step S7).
8) When it is determined that the service is not in service, and when the display element of the display at the time of selection or the display at the time of non-selection is displayed, whether or not the “number of the next priority communication method” is “end”; That is, it is determined whether or not the display of all the communication methods has been completed (step S9). At this time, if it is determined that the display of all the communication methods has not been completed, the “communication method of the next priority order” is determined. The communication method based on the “number” is set as a processing target (step S10), and the above-described operation control (steps S3 to S3) is performed.
S10) is repeated.

On the other hand, "the number of the communication system of the next priority"
If it is determined that the display of all the communication methods has ended with `` End '', the communication method in which the `` selection '' of the parameters of each communication method is `` ● '', that is, the selected communication method The electric field strength of the communication system
The reading is performed from the receiving unit of the F unit 5 (step S11), and the read electric field strength is converted into a level bar to convert it into a level bar.
3 (step S12), and displays the in-range / out-of-range determination on the display unit 13 based on the “usability (service availability)” of each communication method (step S13).

The display unit 1 is controlled by the above operation control.
3, the communication methods that are actually available and are in service are arranged in priority order from the left, and the character display of the selected communication method is displayed as the character displayed when selected, and is not selected. When the user operates the mode key of the input unit 16 (step S14) in a state where the character display of the communication method is displayed by the non-selected display element, the parameter of the currently selected communication method is used. Recognize "the number of the next priority communication method" (step S15), and if the recognized number is "end", select the highest priority communication method (steps S16 and S17), and Recognized number is "end"
If not, the communication system of the recognized number is selected (steps S16 and S18), the selection mark "●" is moved to the selected communication system (step S19), and the above-described operation control (steps S4 to S4) is performed. S13) is performed to update the display content of the display unit 13.

That is, for example, as shown in FIG. 4, “1” is stored as the number of the highest priority communication means, and “2” is stored as the number of the highest priority communication method of the PHS group.
"Mobile" as the communication method of the number "1", "2" as the number of the next priority communication method, "Mobile" as the group type, "●" as the selection, and the display element (when not selected) "Mobile" as the display element (when selected), "black and white" inversion of "mobile", "possible" as usable or non-usable (service possible) as "possible", and communication of number "2". "PHS" as the method, "3" as the number of the next priority communication method, "PHS public" as the group type, "-" as the selection, and "PHS" as the display element (when not selected). , The display element (when selected) is “PHS” black-and-white inversion, and “OK” is
“Available” is stored as the availability (service availability), “OS1” is used as the communication system of the number “3”, “End” is used as the number of the next priority communication system, and “PHS self-employed” is used as the group type. , "-" As a selection, "OS1" as a display element (when not selected), and a display element (when selected)
"OS1" is black and white inverted, and "OK"
Is stored as "usable" (usable or unserviceable), "HS1" is used as the communication method of the number "4", "-" is used as the number of the next priority communication method, and "PHS" is used as the group type. Self-employed, “-” as a selection, “HS1” as a display element (when not selected), “HS1” as a display element (when selected), black / white inversion, “impossible” as usable or non-usable ( If “OK” is stored as “service availability” in FIG.
As shown in FIG.
Is displayed in order from the left, and a bar indicating the radio wave intensity of the mobile phone and the word "PHS" are displayed in order from the left, and the characters of "mobile" and "PHS", which are black and white inverted, are displayed in order from the left. You.

When the mode button of the input unit 16 is pressed once in this state, as shown in FIG.
A bar indicating the radio field intensity of S and the letters “PHS” are displayed in order from the left, and the letters “mobile” and the letters “PHS” inverted in black and white are displayed in order from the left,
Further, when the mode button of the input unit 16 is pressed once in this state, as shown in FIG. 6 (a), a character “mobile” and a bar indicating the radio field intensity of the mobile are displayed above the display unit 13. The letters "PHS" are displayed in order from the left, and the letters "mobile" and "PH"
The letters "S" are displayed in order from the left.

Therefore, according to the above-described operation control, when the display of the communication method is started, only the communication method that is actually usable and is in service among the communication methods mounted on the device body. Since the display elements are displayed in descending order of priority from the left, the communication system with the highest priority can be selected. For example, “PHS” is the first priority and “mobile” is the second priority. In the case of, when you make a temporary call with "mobile" from a place that is not suitable for "PHS" such as in a moving train, "mobile" is the first priority and "PHS" is When the facsimile communication is temporarily terminated in-band using the earphone / microphone jack 10 at the time of the second priority, the telephone is automatically switched to “PHS” or “mobile” when the call or the facsimile communication is completed. Return, frequency Since the communication method high normally used is selected, it is possible to increase the convenience of the user.

Each time the mode button is pressed, the one with the lowest priority is sequentially selected. When the mode button is pressed while the communication system with the lowest priority is selected, the highest priority is selected. Since the selection can be switched cyclically so as to select the communication method, and the reception strength of the selected communication method can be displayed, when communication is started in the selected communication method, As a guideline of how much call quality can be obtained, the selected communication method becomes a communication method used when the user performs a calling operation, and the convenience of the user can be increased.

In the above operation control, while the communication systems that are actually available and in service are arranged in order of priority from the left, the selected communication system is not selected as a display element at the time of selection. The case where the communication method is displayed by the display element of the non-selected display has been described. However, the present invention is not limited to this. For example, only the actually usable communication methods may be displayed regardless of the priority order. In this case, whether or not to display the display element of each communication method may be determined based on the “usability” of the parameter of each communication method, and the communication method is not in service. However, corresponding display elements may be displayed for communication methods that can be actually used. In this case, the characters “mobile” and “PHS” displayed at the top of the display unit 13 are displayed. In addition, when the bar indicating the reception strength is used to indicate that the service is being used, the display of "mobile" or "PHS" is stopped when the mobile or PHS is not in service, and only the OS or HS is in service Only the bar should be displayed.

Further, in the above-described embodiment, the case where the display is performed based on the communication system and the control program built in advance has been described. However, the present invention is not limited to this.
For example, a wireless communication modem or a wired communication modem or the like is added and used, a PCMCIA card slot is provided and a wireless communication card is replaced and used, or service subscription information and the like are stored and replaced on a card. By this, it is possible to increase or decrease the communication method that can be used in the device main body, and for the increased or decreased communication method, a corresponding display element may be displayed when the communication method is actually enabled. The control program is read from the recording medium and stored in the storage unit 17 or received via a wireless base station and stored in the storage unit 17, and the above-described operation control is executed based on the stored control program. Is also good.

As described above, according to the first or seventh aspect of the present invention, since a communication method that can be actually used can be recognized on a single screen, a complicated operation is required. Instead, the user can immediately check the available communication methods.

According to the second or seventh aspect of the present invention, the currently selected communication system can be recognized using the display element representing the actually usable communication system. The user can immediately confirm the available communication method and the currently selected communication method without inviting or requiring a complicated operation.

According to the third or seventh aspect of the present invention, the currently selected communication mode can be recognized by using the display element indicating the actually usable communication mode.
Since the operation required by the user can be reduced, erroneous operation when communication using a plurality of communication methods is enabled can be reduced, and usability can be improved.
