  By the way, in a mobile phone combined with PDC, PHS, etc., not only has a hardware configuration that enables communication using each communication method, but also subscribes to a service that provides each communication method, or a private branch exchange. Only after registration, communication using each communication method becomes possible. Like the above-described conventional device, the LED corresponding to the pressed key is turned on, or PHS is selected when PDC is selected. If the color of the backlight of the display screen is changed from time to time, the communication method such as PDC or PHS can be used unless the communication method is selected for PDC or PHS. There is a problem in that it cannot be performed, a complicated operation is required for the user, and determination cannot be made immediately.

  In addition, in a communication device capable of communication using a plurality of communication methods in this way, it is necessary to display the state / setting of each communication method and the mutual relationship between the communication methods, and displays a variety of information at a time. There was a need. Therefore, it is necessary to enlarge the display screen in the display means or to selectively or automatically display the display by dividing it into a plurality of displays. However, if the display screen is enlarged, the communication device becomes larger and the weight increases. There is a problem that it impedes portability, and there is a problem that the display needs to be operated by the user if the display is divided into multiple parts, and the display is divided into multiple parts automatically. Although what is displayed does not require an operation by the user, there is a problem in that all displays cannot be confirmed in a short time.

  The present invention is a communication method in which communication is enabled by subscribing to a service or registering in a private branch exchange among communication methods in which communication can be used by a hardware configuration without requiring a complicated operation by a user.

Control means of the communication device, the control means refers to the step of storing information indicating the priority order arbitrarily designated by the operator in the storage means, and the information indicating the priority order stored in the storage means Then, a step of sequentially determining communication methods that can actually be used in accordance with the priority order indicated by the information, and storing the availability information of each communication method in a storage unit, and storing in the storage unit as usable The display element pattern corresponding to the communication method being read is read from the storage means, displayed on the display means in an arrangement according to the priority order stored in the storage means, and the priority among the displayed display elements Displaying the display element of the communication method with the first rank as a currently selected communication method with a display form different from the display elements of other communication methods. The processing is executed in the standby state of the communication device, and only the display elements displayed on the display means by the step of displaying are used, the communication method that can actually be used, the priority specified by the operator, and the currently selected The communication method is identifiable so that it can be identified.

  The invention described in claim 2 further includes mode switching operation means for selecting a communication system in addition to the system of the invention described in claim 1, and the storage means is currently selected from the plurality of communication systems. The control means performs processing including the above steps and displays the currently selected communication system on the display means so as to be identifiable, by the operator. When the mode switching operation means is operated, it is determined whether or not the next communication method of the priority order is actually usable. If the communication method is usable, the communication method of the next priority is selected. As a system, the display elements are displayed on the display unit with different display forms from the display elements of other communication systems.

  In the invention described in claim 3, in addition to the system of the invention described in claim 2, the control means determines whether the communication system of the next priority is the result of the determination as to whether or not the communication system of the next priority is actually usable. If it is determined that the communication method is not usable, it is determined whether or not the communication method with the next priority is actually usable. If the communication method is usable, the communication method with the next communication method with the priority is currently selected. As a system, the display elements are displayed on the display unit with different display forms from the display elements of other communication systems.

  According to the first aspect of the present invention, in the standby state of the communication device, the pattern of the display element corresponding to the usable communication method is displayed on the display means in an arrangement according to the priority order, and the displayed display The display element of the communication method with the highest priority among the elements is displayed as a currently selected communication method with a different display form from the display elements of other communication methods and displayed on the display means. Thus, it is possible to make the user recognize the actually usable communication method, the priority specified by the operator, and the currently selected communication method with a single screen.

  According to the second aspect of the present invention, when the operator operates the mode switching operation means for selecting the communication method in a state where the currently selected communication method is displayed on the display means so as to be identifiable. It is determined whether or not the next communication method of the priority order is actually usable, and if it is usable, the communication method of the next communication method is selected as the communication method currently selected as the communication method currently selected. Different display forms are displayed on the display means, and the user can recognize the next communication method in the priority order.

  According to the third aspect of the present invention, when it is determined that the next communication method of the priority order is actually usable as a result of the determination as to whether or not the communication method of the next priority order is actually usable, the priority is further increased. It is determined whether or not the next communication method is actually usable, and if it is usable, the display device of another communication method is displayed as the communication method in which the next communication method of the priority is currently selected. Different forms are displayed on the display means, so that the user can recognize the communication method of the next priority.

  The PDC / PHS combined mobile phone configured as described above is given a mobile phone number by subscribing to a mobile phone (PDC) service, and information necessary for connection is stored in the EEPROM 18. Along with this, actual communication via the PDC radio base station (hereinafter, this communication method is referred to as “mobile”) becomes possible, and a PHS telephone number can be obtained by subscribing to the PHS public network service. And information necessary for connection is stored in the EEPROM 18, and accordingly, actual communication via the PHS radio base station (hereinafter, this communication method is referred to as “PHS”) becomes possible. In addition, by registering with the private PHS exchange, an extension number is given, and information necessary for connection is stored in the EEPROM 18. Actual communication via the PHS exchange (hereinafter referred to as “OS (office station)”) is possible, and an extension number is given by registering with the digital cordless telephone base unit. In addition, information necessary for connection is stored in the EEPROM 18, and accordingly, actual communication via the digital cordless telephone master unit (hereinafter, this communication method is referred to as “HS (Home Station)”) becomes possible. It is like that.

  In addition to the above, in “PHS”, it is possible to use “PHS” in the back of the indoor through a home antenna having a repeater function installed indoors in the service area of the PHS radio base station. Although there is a communication method, etc., detailed description is omitted here.

  In the following, regarding the PDC / PHS composite type cellular phone configured as described above, the operation of “mobile” will be described by dividing it into [standby] [incoming call] [communication] [outgoing call].

  [Standby] When the power is turned on, the microcomputer 12 reads the subscriber number (MSN), the mobile station number (MSI), the perch channel number, etc. from the EEPROM 18, and measures the reception level of the frequency corresponding to all perch channel numbers. A table is created in order and stored in the RAM of the storage unit 17. Then, after switching to the highest level frequency and establishing synchronization (frame synchronization and superframe synchronization) by the channel codec of the PDC baseband unit 4 and the microcomputer 12, broadcast information from the base station side is sent to the microcomputer 12. Is read to check the standby condition and the like, and shifts to the standby channel designated by the broadcast information.

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

  During standby, intermittent reception is performed in which the channel codec of the PDC baseband unit 4 intermittently receives PCH (paging channel) on the common control channel. During standby, the peripheral channel indicated by the own station and broadcast information is received. The electric field strength 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 incoming information on the PCH with the channel codec of the PDC baseband unit 4 every time. As a result of information analysis by the microcomputer 12, if the incoming information is addressed to itself, the mobile station uses the voice codec 7 from the microcomputer 12. Control is performed to output a ringtone to the buzzer 11 or the vibrator 15 is vibrated and the incoming LED 14 is blinked.

  At this time, the PDC radio base station transmits a radio status report consisting of the electric field strengths of the local station and the peripheral channels to the PDC radio base station. Thereafter, the microcomputer 12 passes through the channel codec of the PDC baseband unit 4 to By exchanging messages with, the communication channel is set in accordance with the digital automobile telephone system standard.

  [Communication] In the communication channel, either voice communication or data communication is performed, and during voice communication, the reception is received by the antenna 1 or 2 (switching by diversity), and the PDCRF The signal from the 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 base. A radio wave is transmitted from the antenna 2 through the band unit 4 and the PDCRF unit 3.

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

  [Transmission] When a transmission operation is performed by a key operation or the like of the input unit 16 while waiting for the mobile station, the microcomputer 12 creates a message including the other party number and the peripheral electric field strength, and the channel codec of the PDC baseband unit 4 In addition, the antenna 12 transmits a radio wave to the PDC radio base station via the PDCRF unit 3, and thereafter, the microcomputer 12 exchanges messages with the PDC radio base station via the channel codec of the PDC baseband unit 4. The communication channel is set in accordance with the digital automobile telephone system standard.

  The above is the “mobile” operation. Next, the “PHS” operation will be described by dividing it into [standby (intermittent reception)] [incoming call] [outgoing call]. Note that [communication] is the same as the above-described “mobile” operation, and thus will be omitted. Further, the following will be described assuming that the mobile station is “PS” (Personal Station) and the base station is “CS” (Cell Station) so as not to be confused with the above-described “mobile” operation.

  [Standby (intermittent reception)] When the PS is turned on, the microcomputer 12 reads the CS-ID (CS identification code), PS-ID (PS identification code), etc. from the EEPROM 18 and supplies them to the PHS baseband unit 6, and then the PHS. The baseband unit 6 receives a broadcast channel in which the CS is intermittently transmitted via the antenna 2 and the PHSRF unit 5, and the CS-ID in the received broadcast channel and the CS-ID read from the EEPROM 18 are microcomputers 12 compares, and when this CS-ID matches, the PS validates the information in this broadcast channel.

  Similarly, the paging channel on which the CS performs intermittent transmission is also received, and when the CS-IDs are compared and matched, the information on this channel is also validated and the operation proceeds to the intermittent reception operation. The intensity of radio waves arriving from the CS is measured by the receiving means of the PHSRF unit 5.

  [Incoming] When there is an incoming call during intermittent reception of the PS by CS intermittent transmission, the CS transmits the incoming call information on the general call channel to notify the PS of the incoming call (same procedure as intermittent transmission) . When the PS receives the general call channel containing this incoming call information, the microcomputer 12 controls the voice codec 7 to output the incoming call sound to the buzzer 11 or vibrate the vibrator 15 for the incoming call ringing, and the incoming call LED 14 blinks. After that, connection confirmation information is returned to the CS through the dedicated cell channel.

  [Transmission] In the intermittent transmission of CS, when the transmission operation is performed by the key operation of the PS input unit 16 or the like during the intermittent reception of the PS, the microcomputer 12 uses the baseband unit 6 and the PHSRF unit 5 in the control carrier. A link channel establishment request is transmitted to the CS through the dedicated cell channel. Then, the CS that has received this performs carrier sense of a communication carrier selected at random, and if the slot of that carrier is not used, returns the link channel assignment with the control carrier to the PS and switches to the assigned carrier. And 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 sense, and then transmits a synchronization burst, thereby setting the call channel in accordance with the second generation digital cordless telephone system standard. .

  The above is the operation of “PHS”, detailed description of the operation of “OS” and “HS” is omitted, and the operation when displaying a usable communication method is shown in FIG. This will be described with reference to the explanatory diagrams shown in FIGS.

  The storage unit 17 stores the highest priority communication method and the parameters of each communication method. Among these, the highest priority communication method has the highest priority as shown in FIG. It consists of items of “number of highest priority communication method” and “number of highest priority communication method of PHS group” representing communication methods, and parameters of each communication method are as shown in FIG. "Number" representing the system, "Communication system" representing the actual communication system, "Number of communication system of the next priority" representing the communication system to be transferred next, and which group the communication system belongs to "Group type" to indicate, "Select" to indicate the communication method being selected, "Display element (when not selected)" to indicate the display element when not selected, "Display element (when selected)" to indicate the display element when selected The communication method is registered and ready for use. Dolphin whether "usability" and communication method represent is composed of the item of "usability (Service availability)" indicating whether the current service available.

  The “highest priority communication method number”, “PHS group highest priority communication method number”, and “next priority communication method number” are detected by the receiving means of the PDCRF unit 3 and the PHSRF unit 5. Then, it is automatically set by out-of-service / out-of-range detection based on the received electric field strength and synchronization output, or manually set by the operation of the input unit 16 by the user. ) And FIG. 5B, an example of the priority order of group types is displayed on the display unit 13 for selection, and then, as shown in FIG. 5C and FIG. 5D. An example of the priority order within the group may be displayed on the display unit 13 and selected. This priority order is the order of selection of the communication method to be used when making a call, the order of selection of the communication method selected for the display of the radio field strength level, the order of switching the communication method when the mode button is pressed, This is used as a communication method selection order when automatic transmission is performed by automatically switching to another communication method when transmission fails.

  The “usability” is set by data stored in the EEPROM 17, and “usability (service availability)” is the received electric field strength detected by the receiving means of the PDCRF unit 3 and the PHSRF unit 5, the synchronization, etc. This “usability” is updated every time a new communication method is registered in the EEPROM 17, and “usability (service availability)” is an intermittent reception in the “standby” operation. Updated regularly by.

  In this way, in the state where the highest priority communication method and parameters of each communication method are stored in the storage unit 17, when the first display is performed, such as when the power is turned on or communication is completed, First, the highest priority communication method stored in the storage unit 17 is selected in the parameters of each communication method stored in the storage unit 17 (step S1), that is, the item “selection” in the parameters of the highest priority communication method. "●" is moved to clear the display on the display unit 13 (step S2), and the highest priority communication method stored in the storage unit 17 is set as the processing target (step S3).

  Then, the parameters of the communication method to be processed are acquired from the storage unit 17 (step S4), and it is determined whether or not the service is being selected (steps S5 and S6), and at the same time the service is being selected and selected. When it is determined that the display element is selected, the display element at the time of selection is displayed left-justified on the display unit 13 (step S7). When it is determined that the service is in progress and is not selected, the display element at the time of non-selection is displayed. Is displayed on the display unit 13 in the left-justified direction (step S8), when it is determined that the service is not being performed, and when the display element of the display at the time of selection or non-selection is displayed, "Is" End ", that is, whether or not the display of all the communication methods is completed (step S9), and at this time, it is determined that the display of all the communication methods is not completed. Case Repeats the communication scheme processed based on the "next priority number of a communication system" (step S10), and the above-described operation control (step S3 to S10).

  On the other hand, if it is determined that the display of all the communication methods is ended because “the number of the communication method of the next priority” is “end”, the “selection” among the parameters of each communication method is “●”. Is read from the receiving means of the PDCRF unit 3 or PHSRF unit 5 (step S11), and the read electric field strength is converted into a level bar and displayed. In addition to displaying on the unit 13 (step S12), based on the “usability (service availability)” of each communication method, the range / out-of-range determination is displayed on the display unit 13 (step S13).

  The communication methods that can be actually used on the display unit 13 by the above-described operation control and are in service are arranged in order of priority from the left, and the character display of the selected communication method is the character displayed at the time of selection. When the user operates the mode key of the input unit 16 in a state where the character display of the communication method that is not selected is displayed as a non-selected display element (step S14), The "communication method number of the next priority" is recognized from the parameters of the selected communication method (step S15). If the recognized number is "end", the highest priority communication method is selected. (Steps S16 and S17) If the recognized number is not “end”, the communication method of the recognized number is selected (Steps S16 and S18). Move selection mark "●" in the communication system respectively selected (step S19), and updates the display contents of the display unit 13 by performing the above-described operation control (step S4~S13).

  That is, for example, as shown in FIG. 4, “1” is stored as the number of the highest priority communication means, “2” is stored as the number of the highest priority communication method of the PHS group, and the communication method of the number “1” is stored. As “Mobile”, “2” as the communication method number of the next priority, “Mobile” as the group type, “●” as the selection, and “Mobile” as the display element (when not selected) The black and white reversal of “mobile” is stored as an element (at the time of selection), “available” is stored as availability, “available” is stored as availability (service availability), and “PHS” is stored as the communication method of number “2” "3" as the communication method number of the next priority, "PHS public" as the group type, "-" as the selection, "PHS" as the display element (when not selected), and display element (when selected) "PHS" black-and-white reversal “Permitted” is stored as “Availability (service availability)”, “OS1” is the communication method of the number “3”, “End” is the number of the communication method of the next priority order, "PHS self-employed" as the type, "-" as the selection, "OS1" as the display element (when not selected), black and white inversion of "OS1" as the display element (when selected), "Yes" as the availability “Not available” is stored as availability (service availability), “HS1” as the communication method of the number “4”, “−” as the number of the communication method of the next priority, and “PHS self-employed” as the group type. "-" As a selection, "HS1" as a display element (when not selected), black-and-white reversal of "HS1" as a display element (when selected), "impossible" as availability or not (service) (Yes / No) In the first display, as shown in FIG. 6A, the characters “mobile”, a bar indicating the radio wave strength of the mobile, and the characters “PHS” are displayed at the top of the display unit 13. The characters “mobile phone” and the characters “PHS” which are displayed in black and white are displayed in order from the left.

  In this state, when the mode button of the input unit 16 is pressed once, as shown in FIG. 6B, a bar indicating the character of “mobile” and the radio wave intensity of the PHS is displayed at the top of the display unit 13. And “PHS” are displayed in order from the left, and “mobile” and black-inverted “PHS” are displayed in order from the left. In this state, the mode of the input unit 16 is displayed. When the button is pressed once, as shown in FIG. 6A, a character “mobile”, a bar indicating the radio wave strength of the mobile, and a character “PHS” are displayed on the upper part of the display unit 13 from the left. The characters “mobile phone” and the characters “PHS” which are displayed in black and white are displayed in order from the left.

  Therefore, according to the above operation control, from the left, only the communication methods that are actually usable and in service among the communication methods installed in the device main body are displayed from the left. Since display elements can be displayed in order of highest priority and the communication method with the highest priority can be selected, for example, when “PHS” is first in priority and “mobile” is second in priority. , When you make a temporary call with "mobile" from a place that is not suitable for use with "PHS", such as on a moving train, or "mobile" is first and priority is "PHS" In the second place, when using the earphone microphone jack 10 to temporarily perform in-band facsimile communication or the like, when the telephone call or facsimile communication is terminated, the frequency automatically returns to “PHS” or “mobile”. High normal use Since the communication method is selected, it is possible to increase the convenience of the user.

  Also, each time the mode button is pressed, the one with the lowest priority is sequentially selected, and the communication method with the highest priority is selected when the mode button is pressed while the communication method with the lowest priority is selected. The selection can be switched cyclically to select, and the reception strength of the selected communication method can be displayed, so when starting communication with the selected communication method, how much In addition to being a measure of whether call quality can be obtained, the selected communication method becomes a communication method used when the user performs a call operation, and the convenience of the user can be increased.

  In the above operation control, the communication methods that are actually available and in service are arranged in order of priority from the left, and the communication method that is not selected is selected as a display element when the selected communication method is selected. Although the case where each display element is displayed in the non-selection display element has been described, the present invention is not limited to this. For example, only actually usable communication methods may be displayed regardless of the priority order. In this case, it is sufficient to determine whether or not to display the display element of each communication method based on the “usability” of the parameter of each communication method, and even if it is a communication method that is not in service. The corresponding display elements may be displayed for the communication methods that can be used in this case. In this case, the characters “mobile” and “PHS” displayed at the top of the display unit 13 and the reception strength are displayed. Is used for the display indicating that the service is in progress, the display of “mobile” or “PHS” is stopped when the mobile phone or PHS is not in service, and only the bar when the OS or HS is in service only Should be displayed.

  In the above embodiment, the case where display is performed based on a communication method and 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 is added. Can be used, or a PCMCIA card slot is provided, the wireless communication card is replaced, or the service subscription information is stored in the card and replaced. The communication element to be increased or decreased may be displayed, and the corresponding display element may be displayed when the communication method becomes actually usable. Further, the above control program is read from the recording medium and stored in the storage unit 17. Or received via the radio base station and stored in the storage unit 17, and the above-described operation is performed based on the stored control program. It is also possible to perform the control.

  According to the embodiment described above, since a communication system that can actually be used can be recognized on a single screen, the user can immediately check the communication system that can be used without requiring a complicated operation. can do.

  In addition, the display element that represents the communication method that can actually be used can be used to recognize the communication method that is currently selected, so that the user can use the display screen without increasing the size of the display screen or requiring complicated operations. It is possible to immediately confirm the possible communication method and the selected communication method.

  In addition, it is possible to recognize the currently selected communication method using display elements that represent the communication methods that can actually be used, and to reduce the operations required by the user, so communication using a plurality of communication methods is possible. In this case, it is possible to reduce the erroneous operation and improve the usability.

  In addition, a display element representing a communication method that can be actually used can be used to recognize a communication method being selected, and a display area for reporting communication method quality information can be used in a plurality of communication methods. Therefore, the user can immediately confirm the quality of the communication method used for the communication immediately before the start of communication, and the display area can be shared by a plurality of communication methods. Can also be prevented.

  Furthermore, the priority of the communication method can be recognized using display elements that represent the communication methods that can actually be used, so that the user can use the display screen without enlarging the display screen or requiring complicated operations. Possible communication methods and their priorities can be confirmed immediately.
