  As shown in Patent Document 1, there are various differences between overseas telecommunications carriers and domestic telecommunications carriers not only in the voice compression method but also in other services provided. For example, e-mail cannot be used in some countries, and videophones cannot be used.

  Furthermore, the mobile phone has an address book in which phone numbers of acquaintances, friends, etc. are registered in advance. Normally, a user performs a call process without inputting all the phone numbers by using this address book. Yes. However, it is considered that telephone numbers registered in the normal address book are often registered on the assumption that they will be used in Japan, and telephone numbers are not registered on the assumption that they will be used overseas. Absent. Therefore, when trying to make a call using an address book from overseas, the registered phone number format is different, that is, the number of digits in the phone number is different, or the country code is required, so the call cannot be processed. is there.

  Accordingly, in order to solve the above-described problems, an object of the present invention is to provide a communication device and an operation confirmation method that can notify a user of operation confirmation of a communication device such as a mobile phone that can be used overseas.

  In order to solve the above-described problem, the communication apparatus of the present invention is recognized by the recognition unit that recognizes the region information indicating the region of the communication network to be connected to the communication unit, and when the calling process is performed. Judgment means for judging whether or not the area is a predetermined area, and a notifying means for notifying the fact that the area recognized by the recognition means by the judging means is not a predetermined area And.

  In the operation confirmation method of the present invention, the recognition step for recognizing the region information indicating the region of the communication network to be connected for communication and the region information recognized by the recognition step when the calling process is performed are determined in advance. A determination step for determining whether or not the region information is determined, and a notification step for notifying the fact that the region information recognized by the recognition means in the determination step is not predetermined region information. I have.

  According to the present invention, when the area information indicating the area of the communication network to be connected for communication is recognized and the transmission process is performed, it is determined whether or not the recognized area information is the predetermined area information. . If the recognized area information is not predetermined area information, the fact can be notified. As a result, the user can recognize that he / she is not in a predetermined area prior to the outgoing call processing. For example, when he / she is in a foreign country and tries to make a call using the address book, the so-called home network It is possible to recognize that the user is not in the country, and it is possible to prevent or reduce the situation where the outgoing call processing cannot be performed normally.

  Moreover, it is preferable that the alerting | reporting means in the communication apparatus of this invention alert | reports to a user so that operation confirmation may be performed.

  According to the present invention, the user can be notified to confirm the operation, and the user can be recognized so as not to perform an erroneous call process. Therefore, for example, when you are in a foreign country and you try to make a call using the address book, you need to confirm the operation, such as the need to enter a country code or 0 for the entered phone number. Therefore, it is possible to prevent or reduce the situation where the calling process cannot be normally performed.

  The communication device of the present invention further includes subscriber information storage means for storing carrier information indicating a contracted communication carrier and area information indicating a region to which the communication carrier belongs, and the determination means. It is preferable to determine whether or not the area information recognized by the recognition means is the area information stored in the subscriber information storage means.

  According to this invention, the subscriber information storage means such as USIM stores and recognizes the carrier information indicating the contracted telecommunications carrier and the regional information indicating the region to which the telecommunications carrier belongs. By comparing the stored area information with the stored area information, the user can recognize that he / she is not in the area where he / she normally resides when trying to use the communication device in an area where he / she is not normal such as overseas. .

  The communication device of the present invention further includes storage means for storing a database indicating a region and a telecommunications carrier provided in the region, and the recognizing unit recognizes the region information, Recognizing person information, and the determining means determines whether or not the area information recognized by the recognizing means is predetermined area information. Is determined whether or not the information is predetermined business information, and the notification means determines that both the regional information and the business information are not predetermined regional information and business information by the determination means. Informs the user of the telecommunications carrier that provides the telecommunications business in the area indicated by the regional information recognized by the recognition means based on the database stored in the storage means. It is preferable.

  According to the present invention, in addition to determining whether or not the recognized area information is predetermined area information, it is determined whether or not the recognized company information is predetermined company information. If it is determined that neither the regional information nor the business operator information is predetermined regional information and business operator information, the business operator information providing the communication business in the area indicated by the recognized regional information is stored in the database. Based on this, the user can be notified. Therefore, the user can know which telecommunications carrier provides the service at the location where the user is currently located, and can understand why the calling process cannot be performed.

  Further, the storage means in the communication apparatus of the present invention further stores destination information indicating a request destination of a service list indicating a service that can be provided by the communication carrier in association with the communication carrier, and is recognized by the determination means. If the regional information recognized by the means is not predetermined regional information, but the business information recognized by the recognition means is determined to be predetermined business information, the business operator recognized by the recognition means It is preferable that the information processing apparatus further includes an acquisition unit that acquires destination information of information from the storage unit and acquires a service list based on the acquired destination information.

  According to this invention, when it is determined that the recognized regional information is not the predetermined regional information but the recognized business information is the predetermined business information, it corresponds to the recognized business information. Destination information to be acquired, and a service list can be acquired based on the acquired destination information. Therefore, it is possible to know what service can be received at the location where the user is currently located, and it is possible to provide an easy-to-use communication device.

  According to the present invention, the user can recognize that he / she is not in a predetermined area prior to making a call. For example, when he / she is in a foreign country and tries to make a call using an address book, a so-called home is provided. It is possible to recognize that the user is not in the country of the network, and prevent or reduce the situation where the outgoing call processing cannot be performed normally.

In addition, USIM18 and USIM105 point out the same thing here. Hereinafter, each functional block will be described based on the functional blocks shown in FIG.

  The RF unit 101 is a part that processes a radio signal received via the antenna 101 a, and outputs the processed radio signal to the communication processing unit 103. In the present embodiment, the RF unit 101 receives, in addition to a radio signal composed of a voice signal, a data signal, and the like, broadcast information broadcasted by a base station for connecting to a mobile communication network, and outputs it to the communication processing unit 103. Part. The broadcast information output from the base station includes a country code, a provider code, and base station information. The country code is information indicating the country in which the base station is located (or receiving service provision), the operator code is code information indicating the communication operator providing the communication service, and there are a plurality of base station information. This is identification information for specifying a certain base station.

  The operation unit 102 is a part that operates the communication device 100 such as a numeric keypad, and accepts a telephone number or a call instruction when performing call processing for making a call. When the telephone number and the call instruction are accepted, the operation unit 102 instructs the communication processing unit 103 to perform the communication connection process. In addition, the operation unit 102 accepts input from the user.

  The communication processing unit 103 is a part that extracts the country code indicating the country in which the communication device 100 is located, the operator code, and the base station information from the notification information received from the base station. The extracted country code, operator code, and base station information are output to determination section 106. In addition, when the communication processing unit 103 receives a transmission instruction by an operation from the operation unit 102, the communication processing unit 103 performs a transmission process and a communication process.

  The USIM management unit 104 is a part that performs recognition processing on the USIM 105 when a predetermined condition is satisfied, such as when the communication device 100 is powered on. The USIM management unit 104 is a part that extracts and temporarily stores an IMSI (International Mobile Subscriber Identity) including a country code and a carrier code stored in the USIM 105 after the recognition process. . When the USIM management unit 104 receives a call instruction from the operation unit 102, the USIM management unit 104 outputs a country code to the determination unit 106, and causes the determination unit 106 to determine whether the country codes match or do not match.

  The USIM 105 is a storage unit that stores subscriber information such as a user ID and a telephone number, IMSI, that is, a carrier code indicating a contracted communication carrier, and a country code indicating a country to which the communication carrier belongs. The USIM 105 is detachably attached to the communication device 100. The country code stored in the USIM 105 indicates the country to which the telecommunications carrier with the main contract belongs, that is, the so-called home network country. The home network described below is used in that sense.

  The determination unit 106 is a unit that determines whether or not the information is different from the information stored in the USIM 105 based on the country code and the operator code output from the communication processing unit 103. That is, the determination unit 106 compares the country code output from the communication processing unit 103 with the country code stored in the USIM 105. If the determination unit 106 determines that the country codes are different, the determination unit 106 outputs an instruction to generate a message to the message generation unit 108.

  The memory 107 is a part that stores predetermined fixed help information, and is a part that stores a plurality of help information that is a message corresponding to a determination result by the determination unit 106. For example, if it is determined that the country codes are different, the message is stored so that a message such as “add + and country code to the beginning and take the leading 0” can be provided. This standard help information is created so that “country name” or “home network country” can be replaced with the country name based on the country code, etc. The name of the actual country will be pasted.

  The memory 107 stores a database in which country codes and country names are associated with each other as shown in FIG. In the figure, the country code is shown in an abbreviated form such as xxx. In the above-described help information, the country name is read from the country code based on this database, and the country name is pasted on the corresponding part of the help information.

  The message generation unit 108 is a part that generates help information, which is a message for confirming the state of the communication device and the operation of the user, using the standard help information stored in the memory 107. The message generation unit 108 reads out the country name based on the country code stored in the USIM 105, and generates help information by pasting the country name read out in the "Home network country" column in the standard help information. . Similarly, the country code acquired by the communication processing unit 103 is pasted on the “country name” of the standard help information by pasting the country name according to the database to generate help information. The message generation unit 108 outputs the generated help information to the display 109.

  For example, the message generation unit 108 generates a help information message shown in FIG. FIG. 5 is a diagram showing a screen example (message example) of the display 109 that displays help information. According to FIG. 5, when calling processing is performed for “Home network country”, a telephone number is displayed. The user is informed of a message that the international call identification code “+” and the country code are added to the head, and 0 indicating the area code at the time of domestic call is unnecessary. In addition, when calling processing is performed for a country (country name) where the user is located, a message is displayed indicating that the calling processing may be performed as it is.

  Here, based on the country code stored in the USIM 105, the message generation unit 108 reads the country name corresponding to this country code from the database in the memory 107. Then, the read country name is pasted in the “home network country” column of the standard help information, and help information is generated. In addition, the country name based on the country code acquired from the broadcast information is read from the database, and the read country name is pasted in the “country name” column of the standard help information to generate help information. Become.

  In FIG. 5, underlined portions of “Please take at the head” and “You can leave it as it is”, an anchor is set for this portion. Therefore, when the user clicks or selects this part, the communication apparatus 100 can access a desired Web page (which can be online or offline), and the user can see an explanation regarding this part. it can.

  In addition to confirming the operation, this help information is used to confirm that the user is aware of the fact that he / she is overseas, such as a country code different from the home network country. It is good also as information for. This is because if the user can recognize that at least the country where the user is currently located is different from the country where the user is always present (for example, the country of the home network), the user can confirm the operation.

  The display 109 is a part that displays help information generated by the message generation unit 108. In addition, the display 109 displays the telephone number input by the operation unit 102.

  Next, the operation of the communication apparatus 100 configured as described above will be described. FIG. 4 is a flowchart showing the operation of the communication apparatus 100 when displaying help information based on the country code.

  When predetermined processing such as power-on is performed, the USIM management unit 104 recognizes the USIM 105 (S101), and the home network country code included in the IMSI is read and stored in the USIM management unit 104. (S102). Next, the broadcast information is received from the base station by the RF unit 101, and the country code included in the broadcast information is grasped by the communication processing unit 103 (S103).

  The determination unit 106 compares the country code recognized by the communication processing unit 103 with the country code stored in the USIM management unit 104 (the country code stored in the USIM 105) (S104). Here, if it is determined by the determination unit 106 that the country codes match (S104: NO), the standby state (for example, reception standby state) is continued, and the process of grasping the notification information periodically received is performed. Is called. In addition, when there is an incoming call process and an outgoing call process in the meantime, the respective processes are performed.

  Further, when the determination unit 106 determines that the country codes do not match (S104: YES), when only the country code is different among the plurality of fixed help information stored in the memory 107 by the determination unit 106 A flag is set so that the corresponding standard help information is read (S105). Thereafter, when a call operation is received from the operation unit 102 by the user's operation (S106), the communication processing unit 103 performs a process of temporarily stopping the call operation (S107), and the message generation unit 108 uses the country code of the home network. Help information based on the country code in which the user is located is generated, and the help information is displayed on the display 109 (S108).

  When the help information is displayed on the display 109, the user can recognize the continuation of the outgoing call operation, and when the user performs an operation not to continue in the operation unit 102 (S109: NO), A predetermined change is performed by a user operation on the operation unit 102, for example, the input telephone number is changed, and the communication processing unit 103 performs outgoing call processing to the changed telephone number (S110). If the user performs a continuous operation (S109: YES), the transmission operation is continued as it is, and the communication processing unit 103 transmits the call to the telephone number input in the process of S106 by the operation unit 102. Is performed (S111).

  As described above, when it is determined that the communication device 100 is in an overseas roaming service area based on the country code, help information that calls attention to a call operation can be displayed. Therefore, it is possible to prevent or reduce outgoing mistakes, and to provide an easy-to-use communication device 100.

  Next, a modification of this embodiment will be described. In this modification, in addition to the country code, it is intended to display help information by looking at the agreement of the business code. The functional blocks of the communication apparatus 100 in this modification are the same as those of the communication apparatus 100 of the present embodiment, but some of the configurations have the following differences. That is, in order to perform such processing, in the communication apparatus 100, the USIM management unit 104 extracts the business code in addition to the country code from the USIM 105, and the determination unit 106 determines whether the country code matches or does not match. At the same time, a process for determining whether the business code matches or does not match is performed. Further, the memory 107 needs to store the database shown in FIG. FIG. 6 is an explanatory diagram illustrating a specific example of the database in the memory 107 of the communication apparatus 100 according to the modification. As shown in FIG. 6, in addition to the country code and the country name, the database stores a partner company code and a partner company name in association with each other. For example, here, country code “XXX”, country name “Korea”, partner company code “aaa”, partner company name “XX Telecom”, partner company code “bbb”, partner business It is shown that the person name “xxx phone” is stored in association with each other.

  If the determination unit 106 determines that the business operator codes match, the determination unit 106 outputs the fact to the message generation unit 108, and the message generation unit 108 displays the help information shown in FIG. 5 (that is, the help information in the present embodiment). ) Is generated and displayed on the display 109. If the determination unit 106 determines that the business operator codes do not match, the determination unit 106 outputs a message to that effect to the message generation unit 108, and the message generation unit 108 displays the help information shown in FIG. Help information) is generated and displayed on the display 109.

  Specifically, the message generation unit 108 is a service only in the “partner name” area within “country name” in FIG. In the standard help information described as “...”, the part indicated in square brackets (“country name”, “partner company name”) is the country code and company code obtained from USIM105. Using the database stored in the memory 107, the country name corresponding to the country code and the partner company name corresponding to the company code are acquired, and the country name and partner company name are pasted to the standard help information. And generate help information. That is, the message generator 108 pastes the acquired country name and partner company name in the “country name” field and the “partner company name” field of the standard help information shown in FIG. Will be generated. In addition, it is not restricted to the help information shown in FIG. 7, The communication carrier which can receive a service in the country in which the communication apparatus 100 is located should just be displayed with help information. It is also preferable to include in the help information that it cannot be used because it is outside the service area.

  As described above, in the communication apparatus 100 according to the modification, the determination unit 106 can display help information based on the provider code by determining whether the provider code matches or does not match the country code.

  Next, the operation of the communication apparatus 100 in this modification will be described. FIG. 8 is a flowchart showing the operation of the communication apparatus 100 when help information is displayed using a business operator code.

  When predetermined processing such as power-on is performed, the USIM management unit 104 recognizes the USIM 105 (S201), the home network country code and the operator code included in the IMSI are read, and the USIM management unit 104 (S202). Next, broadcast information is received from the base station by the RF unit 101, and the country code and the operator code included in the broadcast information are grasped by the communication processing unit 103 (S203).

  The judgment unit 106 compares the country code recognized by the communication processing unit 103 with the country code stored in the USIM management unit 104 (country code stored in the USIM 105) (S204). Here, if the determination unit 106 determines that the country codes match (S204: NO), the standby state (for example, reception standby state) is continued, and processing for grasping the notification information received periodically is performed. Is called. In addition, when there is an incoming call process and an outgoing call process in the meantime, the respective processes are performed.

  If the determination unit 106 determines that the country codes do not match (S204: YES), it is further determined whether or not the company code received by the communication processing unit 103 matches the partner company code. It is judged by 106 (S205). If it is determined that the operator codes match (S205: NO), help information display processing is performed when the country codes do not match. Specifically, the processing of S105 to S111 in FIG. 4 is performed.

  If it is determined that the operator codes do not match (S205: YES), the help information can be displayed so that the help information when the country code and the operator code are different is displayed. Standard help information is flagged. Thereafter, when a call instruction is received from the operation unit 102 by a user operation (S206), a process for temporarily stopping the call operation by the communication processing unit 103 is executed (S207), and the help information flagged on the display 109 is displayed. (S208). Here, the help information shown in FIG. 7 is displayed on the display 109, and the transmission operation by the communication processing unit 103 ends (S209).

  As described above, if the country code is different and the business operator code is different from the partner business operator code, the service area is not covered at the location where the user is currently located. By doing so, it is possible to notify the user why communication is not possible. Therefore, it is possible to provide a communication device 100 that is easy to use.

  Next, a second modification of the present embodiment will be described. The functional block of the communication device 100 in the second modification has the same configuration as that of the communication device 100 of the present embodiment, but has the following differences with respect to some configurations.

  That is, the memory 107 of the communication apparatus 100 in the second modification example stores the database shown in FIG. FIG. 9 is an explanatory diagram showing a specific example of the database. As is clear from FIG. 9, in the second modification, in addition to the country code, country name, partner company code, and partner company name, SMS (Short Message Service) destination number is stored in association with each other. Yes. As will be described later, the communication processing unit 103 can make a service list request using this SMS destination number.

  The memory 107 stores an SMS request message for requesting a service list.

  Further, the memory 107 stores the help information shown in FIG. 10 in addition to the help information shown in FIGS. FIG. 10 is a diagram illustrating a screen example of the display 109 that displays help information in the second modification. According to FIG. 10, in the second modification, the current “partner company name” is included in the help information, so that the user can be notified of which partner company can be currently connected. Furthermore, the help information shown in FIG. 10 can notify the user that the service list can be acquired using SMS. The user can select YES / NO by operating the operation unit 102. When the user selects a service list request, the communication processing unit 103 performs the following processing.

  That is, the communication processing unit 103 obtains a request message stored in the memory 107 after the message is generated by the message generation unit 108 and the help information is displayed on the display 109, and is transmitted by SMS and a response to the request message. A function to receive certain list data has been added. The communication processing unit 103 displays the received list data on the display 109, whereby the user can be informed of services that can be used in the current service area. After the service list is displayed, when the user operates the operation unit 102, the communication processing unit 103 can be instructed whether to continue the transmission process to be performed or to interrupt the transmission process. The communication processing unit 103 performs a process of continuing or interrupting the calling process according to the instruction.

  In addition, the message generation unit 108 acquires the name of the affiliated business operator corresponding to the business operator code of the notification information received by the communication processing unit 102 from the database of the memory 107, and the help information “ Help information can be generated by pasting a company name based on the company code included in the notification information in the “partner company name” column.

  The operation of the communication apparatus 100 of the second modified example configured as described above will be described. FIG. 11 is a flowchart illustrating the operation of the communication apparatus 100 according to the second modification. When predetermined processing such as power-on is performed, the USIM management unit 104 recognizes the USIM 105 (S301), the home network country code and operator code included in the IMSI are read, and the USIM management unit 104 (S302). Next, broadcast information is received from the base station by the RF unit 101, and the country code and the operator code included in the broadcast information are grasped by the communication processing unit 103 (S303).

  The determination unit 106 compares the country code recognized by the communication processing unit 103 with the country code stored in the USIM management unit 104 (the country code stored in the USIM 105) (S304). Here, if the determination unit 106 determines that the country codes match (S304: NO), the standby state (for example, the reception standby state) is continued and the process of grasping the notification information periodically received is performed. Is called. In addition, when there is an incoming call process and an outgoing call process in the meantime, the respective processes are performed.

  If the determination unit 106 determines that the country codes do not match (S304: YES), it is further determined whether or not the business operator code received by the communication processing unit 103 matches the partner business operator code. It is judged by 106 (S305). If it is determined that the business code does not match (S305: YES), help information display processing is performed when the country codes do not match and the business code does not match (S306). Specifically, the processing of S206 to S209 in FIG. 8 is performed. In other words, in the country indicated by the country code acquired in the notification information, the calling process is stopped, and it can be used only in the area of the contracted business operator stored in the USIM 105 and out of the area at the current location. Help information indicating that it is unusable is displayed.

  If the determination unit 106 determines that the provider codes match (S305: NO), a flag is set in the standard help information for making a service request so as to perform a service list request process using SMS. Thereafter, when a call instruction is received from the operation unit 102 by a user operation (S307), a process of temporarily stopping the call operation by the communication processing unit 103 is executed (S308), and the fixed help information flagged on the display 109 is displayed. Help information generated based on the information is displayed. Here, as described above, the help information shown in FIG. 10 is displayed on the display 109, and an inquiry is made as to whether or not to request a service list by SMS (S309). The service list request is transmitted to a predetermined server. When the server receives a message indicating a request for a service list, it extracts a service that can be provided based on the contract contents by the contractor, and returns the extracted service name as a service list.

  Here, when the user requests the service list using SMS and cannot receive the response, or when the service list is not requested (S310: NO), the help information shown in FIG. 5 is displayed. Thereafter, it is accepted from the user whether or not to continue the outgoing call process. And according to a user's operation, the transmission operation | movement which continues transmission operation | movement or added the predetermined change is performed. These processes are the same as the processes of S108 to S111 in FIG.

  When a service list, which is a response to a service list request using SMS, is received by the communication processing unit 103 (S310: YES), the service list is displayed on the display 109 (S312). Whether or not to continue is received from the user (S313). Then, when an instruction to continue is received by the operation of the user by the operation unit 102 (S313: YES), the transmission operation is continued by the communication processing unit 103, and the transmission process is performed (S314). When an instruction not to continue is accepted (S313: NO), the transmission processing by the communication processing unit 103 is stopped. Thereafter, the user can refer to the service list and instruct the communication processing unit 103 to perform the calling process or the data communication connection process so that an arbitrary service can be received.

  By performing the above processing, what services can be received by the user requesting a service list indicating the services that can be received in the area where the communication apparatus 100 is located using SMS. I can know.

  Next, operational effects of the communication device 100 of the present embodiment will be described. In the communication apparatus 100 according to the present embodiment, the communication processing unit 103 extracts a country code from broadcast information distributed from a base station in a communication network to be connected for communication. The determination unit 106 compares the country code acquired by the USIM management unit 104 when the power is turned on with the country code acquired by the communication processing unit 103. If the determination unit 106 determines that they do not match, the message generation unit 108 generates help information for notifying the user of the operation confirmation and outputs the help information to the display 109. This help information may be information for recognizing that the user is abroad, such as having a country code different from the home network country, in addition to making the operation confirmation. The display 109 displays the help information. Accordingly, when the user tries to use the communication device 100, the user can recognize that he / she is not in a predetermined area. For example, when he / she is in a foreign country and tries to make a call using the address book, It is possible to recognize that the country is not in a so-called home network, and it is possible to prevent or reduce a situation in which transmission processing cannot be performed normally. More specifically, when you are in a foreign country and you try to make a call using the address book, you need to enter a country code or confirm that the entered phone number does not require 0. Therefore, it is possible to prevent or reduce the situation where the transmission process cannot be performed normally.

  In the communication device 100 according to the modification of the present embodiment, the determination unit 106 determines whether the country code extracted from the notification information is the country code stored in the USIM management unit 104. In addition, it is determined whether or not the business operator code extracted from the notification information is a business operator code stored in the USIM management unit 104. Here, when the determination unit 106 determines that neither the country code nor the company code is the country code and the company code stored in the USIM management unit 104, it is indicated by the country code extracted from the broadcast information. It is possible to notify the user of the telecommunications carrier provided in the country to be displayed on the display 109 based on the database stored in the storage unit 107. Therefore, the user can know which telecommunications carrier provides the service at the location where the user is currently located, and can understand why the transmission process cannot be performed.

  In the communication apparatus 100 according to the second modification of the present embodiment, the country code extracted from the notification information is not the country code stored in the USIM management unit 104, but the business code extracted from the notification information is the USIM management unit 104. When the determination unit 106 determines that the business code is stored in the communication code, the communication processing unit 103 acquires destination information corresponding to the extracted business code from the database in the memory 107. Based on the acquired destination information, the communication processing unit 103 can acquire a service list indicating services that can be used in the country where the user is currently located. Therefore, it is possible to know what service can be received at the location where the user is currently located, and it is possible to provide the communication device 100 that is easy to use.
