  Next, operations of the communication system 100 and the mobile device 1 will be described with reference to FIGS. First, channel list creation processing performed by the mobile device 1 according to the embodiment will be described with reference to FIG. Each process of step A1 to step A18 in the sequence of FIG. 6 is performed by the broadcast wave processing unit 25. In particular, each process of step A2 to step A9 is performed by the channel scanning unit 251 and each process of step A11 and step A12 is performed by the remote control ID determination unit 252. In addition, each process of step A13 and step A14 is performed by the service ID determination unit 253, and the process of step A16 is performed by the reception level determination unit 254.

  First, the broadcast wave processing unit 25 initializes a storage area for the broadcast information N1 provided in the memory unit 17 (step A1). Thereafter, the channel scanning unit 251 sequentially starts scanning each physical channel from the broadcast wave of 13 channels (physical channel) in the UHF band (step A2). In this case, the channel scanning unit 251 performs broadcast wave synchronization processing in the broadcast wave receiving unit 13b for each physical channel (scan ch) to be scanned (step A3). The channel scanning unit 251 determines whether or not broadcast wave synchronization has been established by the synchronization processing in step A3 (step A4). If it is determined that synchronization has been established (step A4; Yes), step A5 And the reception level of the broadcast wave whose synchronization has been established is measured (step A5).

  If the channel scanning unit 251 determines in step A4 that the synchronization of the broadcast wave has not been established (step A4; No), the channel scanning unit 251 proceeds to step A8. After step A5, the channel scanning unit 251 acquires program arrangement information such as NIT and SDT from the broadcast information included in the broadcast wave of the scanned physical channel (step A6).

  After step A6, the channel scanning unit 251 extracts the remote control ID and service ID from the broadcast information included in the broadcast wave of the scanned physical channel, and measured the extracted remote control ID and service ID at the stage of step A5. The reception level is stored in the memory unit 17 as channel information C of broadcast information N1 (see FIG. 3) in association with the physical channel of the broadcast wave (step A7).

  After step A7, the channel scanning unit 251 determines whether or not physical channel scanning (processing from step A3 to step A7) has been performed up to 62 channels in the UHF band (step A8). If the channel has not reached 62 channels (step A8; No), the channel number of the scan channel is incremented by 1 (step A9), and the processing from step A3 to step A7 is repeated for the scan channel after this increase. . In step A8, when the scan ch reaches 62 channels (step A8; Yes), the broadcast wave processing unit 25 starts to create a channel list based on the broadcast information N1 stored in the memory unit 17 (step A8). A10).

  The remote control ID determination unit 252 checks the remote control ID information N12 based on the broadcast information N1 stored in the memory unit 17 (step A11), and the remote control ID is duplicated (in the same meaning, the same applies hereinafter). It is determined whether it is included in N12 (step A12). If the remote control ID determination unit 252 determines in step A12 that multiple remote control IDs are included in the remote control ID information N12 (step A12; Yes), the process proceeds to step A13 and overlaps. If it is determined that a plurality of remote control IDs are not included in the remote control ID information N12 (step A12; No), the process proceeds to step A18. In step A18, the broadcast wave processing unit 25 creates a channel list using the channel information C stored in the memory unit 17 in step A7 (step A18).

  In step A13, the service ID determination unit 253 further collates the service ID information N13 based on the broadcast information N1 stored in the memory unit 17 (step A13), and the plurality of service ID determination units 253 respectively correspond to a plurality of overlapping remote controller IDs. It is determined whether or not a plurality of overlapping service IDs are included in the channel information C (step A14). That is, in step A14, it is determined whether or not there is a plurality of channel information C in which both the remote controller ID and the service ID overlap.

  When the service ID determination unit 253 determines in step A14 that the plurality of channel information C respectively corresponding to the plurality of overlapping remote controller IDs includes the plurality of overlapping service IDs, that is, the remote controller If it is determined that there is a plurality of channel information C in which both ID and service ID overlap (step A14; Yes), the process proceeds to step A16. The reception level determination unit 254 further collates the service ID information N13 based on the broadcast information N1 stored in the memory unit 17, and for a plurality of channel information C in which each of the remote control ID and the service ID overlaps. The level of the reception level is determined (step A16), and the broadcast wave processing unit 25 selects the channel information C with the highest reception level for creating a channel list (step A17).

  In addition, when the service ID determination unit 253 determines in step A14 that the plurality of channel information C respectively corresponding to the plurality of overlapping remote controller IDs does not include the plurality of overlapping service IDs, that is, If it is determined that the remote control IDs are duplicated but the service IDs are not duplicated (step A14; No), the process proceeds to step A15. The broadcast wave processing unit 25 selects the channel information C belonging to the living area designated in advance by the living area determining unit 255 or the like for channel list creation (step A15). Note that the channel information C that was not selected is assigned to a free channel number without being discarded. That is, the selected channel information C is assigned according to the remote control ID, and the channel information that has not been selected is finally assigned to the remaining channel number. As a result, the selection range of channel information is not reduced.

  In this case, the broadcast wave processing unit 25 performs the selection in step A15 based on data indicating the channel information C in each living area (data stored in the memory unit 17 in advance). Also, the designation of the residential area by the residential area determination unit 255 or the like is performed by the processing of the sequence in FIG. In the following, the living area means an area where the user who carries the mobile device 1 is mainly present (resident). The user carrying the mobile device 1 moves in various regions, and among the moving regions, the region where the user stays the longest is the region where the user mainly exists (resides).

  And the broadcast wave process part 25 transfers to step A11 after step A15 or step A17. After step A15 or step A17, the remote control ID determination unit 252 checks the remote control ID information N12 again (step A11), and determines whether another overlapping remote control ID is included in the remote control ID information N12. (Step A12), and the processing after Step A12 is executed.

  Next, with reference to FIG. 7, the residential area determination process which the communication system 100 which concerns on embodiment performs is demonstrated. Each process of Step B1 to Step B7 in the sequence of FIG. 7 is performed by the living area determination unit 255 of the mobile device 1, and the process of Step C1 is performed by the control unit 3c of the base station 3.

  When the mobile device 1 starts wireless communication with the base station 3 (for example, when the power of the mobile device 1 is turned on), the living area determination unit 255 sends a communication start notification together with the mobile device ID information to the base station. Transmit to station 3 (step B1). When receiving the communication start notification and the mobile device ID information from the mobile device 1, the control unit 3c of the base station 3 transmits the communication area information related to the base station 3 to the source mobile device 1 (step C1). This communication area information includes information (area ID) corresponding to the area ID information N24 included in the communication area information N21 of the correspondence table information N2 shown in FIG. Note that two types of information (subarea ID and communication area name) corresponding to each of the subarea ID information N25 and the communication area name information N23 may be included.

  When receiving the communication area information from the base station 3, the living area determination unit 255 records (registers) the communication area information in the memory unit 17 (step B2). And the residence area determination part 255 adds only the registration frequency of the registered communication area information by 1 (step B3). That is, the living area determination unit 255 counts the communication area information registration frequency for each communication area information, and records the counted value in the memory unit 17. This registration frequency is updated every predetermined counting period (for example, for one month). Note that the living area determination unit 255 may count the registration frequency (add the registration frequency by 1) at any timing when the broadcast wave reception starts, during reception, or at the end of reception. Alternatively, the registration frequency may be counted at a predetermined cycle (for example, at the beginning of each month), and the registration frequency may not be counted until the next timing when the moving area can be identified.

  In addition, the living area determination unit 255 registers the registration frequency with a weight that increases according to the elapsed time from the time of initial registration or a predetermined time (for example, one day) after the initial registration. The frequency may be counted. For example, assuming that the same communication area information is registered three times, the registration frequency at the first registration is “1”, the registration frequency at the next registration is “1 + 1.2”, and finally (ie, ) (Recently), the registration frequency at the time of registration is counted to be “1 + 1.2 + 1.3”. For this reason, the period during which the mobile device 1 exists in a certain communication area (how long it has existed in the past) is appropriately reflected in the registration frequency. Note that the counting method of the registration frequency is not limited to this, and any counting method may be used as long as the numerical value added to the registration frequency increases with the lapse of time from the time of registration.

  After step B3, the residential area determination unit 255 determines whether or not the total registration frequency of the communication area information has reached a specified value (step B4). The total registration frequency is the total registration frequency of all registered communication area information. In this case, the living area determination unit 255 determines in step B4 whether or not the total registration frequency of all registered communication area information has reached a specified value. In step B4, the residential area determination unit 255 may determine whether there is a communication area in which the registration frequency has reached a specified value among the registered communication area information.

  Moreover, the residence area determination part 255 may perform determination of step B4, after predetermined | prescribed evaluation periods, such as said counting period, in order to reduce power consumption. In this case, the living area determination unit 255 determines whether or not the evaluation period has elapsed in step B4, and if the evaluation period has elapsed, determines whether or not the total registration frequency has reached a specified value. If the evaluation period has not elapsed, the residential area determination process is terminated.

  In step B4, when the total registration frequency reaches the specified value (step B4; Yes), the living area determination unit 255 indicates the communication area indicated by the communication area information with the maximum registration frequency among the registered communication area information. Is specified as a moving area (step B5). In step B4, when the total registration frequency has not reached the specified value (step B4; No), the residential area determination unit 255 ends the residential area determination process.

  After step B5, the living area determination unit 255 specifies a broadcast area corresponding to the movement area (ie, communication area) specified in step B5 based on the correspondence table information N2 (see FIG. 4) (step B6). . The broadcast area refers to two types of information (broadcast area code and broadcast area name) corresponding to each of broadcast area code information N27 and broadcast area name information N28 included in the broadcast area information N26 of the correspondence table information N2 shown in FIG. ).

  In this case, the living area determination unit 255 includes area ID information N24, sub-area ID information N25 and communication area name information N23 included in the communication area information N21, broadcast area code information N27 and broadcast area included in the broadcast area information N26. Based on the name information N28, the broadcast area corresponding to the communication area indicated by the communication area information is specified from the communication area information related to the moving area specified in step B5. Then, after step B6, the residential area determination unit 255 identifies the broadcast area identified in step B6 as the residential area, and records this residential area in the memory unit 17 (step B7).

  As described above, the communication system 100 according to the embodiment automatically designates the living area of the user of the mobile device 1 in advance. Therefore, even in a region where a plurality of broadcast areas overlap, a suitable channel list can be automatically created based on broadcast information (remote control ID and service ID) corresponding to this living area. Therefore, conventionally, when the service ID is different but the remote control ID is the same, the user has to manually set a favorite service ID (broadcast information corresponding to this service ID). In the communication system 100 according to the above, even when the service IDs are different but the remote control ID is the same, a service ID suitable for the user can be automatically set without manual operation.

  Even when the remote control IDs do not overlap, it may be determined whether or not the service IDs overlap, and any one service ID may be selected based on the reception level of the broadcast wave. Further, the communication system 100 is not limited to the residential area determination process shown in the sequence of FIG. 7 described above, and may perform the residential area determination process shown in any of the sequences of FIGS.

Note that the control unit 5c may count the registration frequency (add the registration frequency by 1) at any timing at the start of reception of the broadcast wave, during reception, or at the end of reception.

  And the control part 5c determines whether the total of the registration frequency of communication area information reached the regulation value (step D3). The total registration frequency is the total registration frequency of all registered communication area information. In this case, in step D3, the control unit 5c determines whether or not the total registration frequency of all registered communication area information has reached a specified value. In step D3, the control unit 5c may determine whether there is communication area information whose registration frequency has reached a specified value among the registered communication area information.

  In addition, the control unit 5c may perform the determination in step D3 after a predetermined evaluation period such as the counting period has elapsed in order to reduce power consumption. In this case, in step D3, the control unit 5c determines whether or not the evaluation period has elapsed. If the evaluation period has elapsed, the control unit 5c determines whether or not the total registration frequency has reached a specified value. If the evaluation period has not elapsed, the residential area determination process is terminated.

  In step D3, when the total registration frequency reaches the specified value (step D3; Yes), the control unit 5c identifies a communication area with the maximum registration frequency as a moving area among the registered communication areas (step D3). D4). In step D3, when the total registration frequency has not reached the specified value (step D3; No), the control unit 5c ends the living area determination process.

After step C4, when the living area determining unit 255 receives the moving area information from the network server 5 via the base station 3, the living area determining unit 255 moves based on the received moving area information based on the correspondence table information N2 (see FIG. 4). A broadcast area corresponding to the area (that is, the communication area) is specified (step B10).

  In this case, the living area determination unit 255 includes area ID information N24, sub-area ID information N25 and communication area name information N23 included in the communication area information N21, broadcast area code information N27 and broadcast area included in the broadcast area information N26. A broadcast area is specified based on the name information N28.

<Fourth Modification>
Next, the living area determination process shown in the sequence of FIG. 11 will be described. Each process of step B8 and step B12 of the sequence of FIG. 11 is performed by the living area determination unit 255 of the mobile device 1, and each process of step C2 and step C5 is performed by the control unit 3c of the base station 3. And each process of step D1, step D3, step D4, step D6-step D8 is performed by the control part 5c of the network server 5. FIG. First, the living area determination unit 255, the control unit 3c, and the control unit 5c perform the process of step K5 shown in FIG. And after the control part 5c performs the process of step D8 among step K5, the control part 5c, the control part 3c, and the living area determination part 255 perform the process of step K4 shown in FIG. In the fourth modification, the communication unit 5a of the network server 5 has functions of a server reception unit and a server transmission unit, and the control unit 5c has functions of a server registration unit, a server counting unit, and a server broadcast area specifying unit. Have In addition, the communication unit 13a of the mobile device 1 has a function of a receiving unit, the channel scan unit 251 has a function of broadcast information acquisition unit, and the broadcast wave processing unit 25 has a function of channel list creation unit.

  In the first and third modified examples described above, the communication area information registration frequency is counted not in the mobile device 1 but in the network server 5, so that the burden on the mobile device 1 is reduced. In the second and fourth modified examples, in addition to counting the registration frequency, since the broadcast area is specified not in the mobile device 1 but in the network server 5, the burden on the mobile device 1 is further reduced.

  Note that the above-described mobile device 1 (including the mobile devices 1 of the first to fourth modifications) may be able to add channels to the channel list. FIG. 12 is a flowchart for explaining the channel addition process. When an instruction to add a new channel is input by the user via the operation unit 19 (step A20), the channel scanning unit 251 extracts a remote control ID and a service ID from broadcast information included in the broadcast wave of the new channel to be added. The extracted remote controller ID and service ID are stored in the memory unit 17 as channel information C (referred to as new channel information) of the broadcast information N1 in association with the physical channel of the broadcast wave (step A21). Next, the broadcast wave processing unit 25 refers to the channel list stored in the memory unit 17 and determines whether or not channel information overlapping with the new channel information is included in the channel list (step A22). Specifically, the broadcast wave processing unit 25 includes the physical channel, the service ID, and the remote control ID that are the same as the physical channel, service ID, and remote control ID of the new channel information to be added stored in the memory unit 17 in step A21. It is determined whether or not the information is included in the channel list (step A22).

  At the stage of step A22, if the channel list includes channel information that overlaps with the new channel information (step A22; Yes), the broadcast wave processing unit 25 ends the channel addition processing and overlaps the channel. If the information is not included in the channel list (step A22; No), the process proceeds to step A23, the addition of a new channel is started (step A23), and the process proceeds to step A24. The remote control ID determination unit 252 refers to the channel list stored in the memory unit 17 to collate the channel number (remote control ID) (step A24), and the same channel number (remote control ID) as the remote control ID of the new channel information is obtained. It is determined whether it is included in the channel list (step A24).

  When the channel number (remote control ID) that is the same as the remote control ID of the new channel information is not included in the channel list at step A24 (step A24; No), the broadcast wave processing unit 25 uses the remote control ID of the new channel information. Based on the above, new channel information is added to the channel list (step S25), and the channel list is updated (step A25). If the channel number (remote control ID) identical to the remote control ID of the new channel information is included in the channel list at step A24 (step A24; Yes), the service ID determination unit 253 is stored in the memory unit 17. The service list is checked with reference to the channel list (step A27), and it is determined whether or not the same service ID as the service ID of the new channel information is included in the channel list (step A28).

  When the service ID identical to the service ID of the new channel information is not included in the channel list at step A28 (step A28; No), the broadcast wave processing unit 25 is included in the new channel information and the channel list. The broadcast area corresponding to each of the remote channel ID of the new channel information and the overlapping channel information is collated with the broadcast area corresponding to the living area recorded in the memory unit 17 (step A29). The broadcast wave processing unit 25 is the same as (or in the vicinity of) the broadcast area corresponding to the residential area among the new channel information and the channel information included in the channel list and overlapping with the remote control ID of the new channel information. ) Select channel information corresponding to the broadcast area, record the selected channel information in the channel list, and record other channel information in the channel list after assigning it to an unused unused remote control ID (channel number). (Step A30). Thereafter, the broadcast wave processing unit 25 determines whether or not there is unprocessed new channel information (step A31). If there is unprocessed new channel information (step A31; No), the process proceeds to step A24. The above process is repeated.

  When the service ID identical to the service ID of the new channel information is included in the channel list at step A28 (step A28; Yes), the broadcast wave processing unit 25 sets the new channel information to an unused unused channel information. Is assigned to the remote controller ID (channel number) and recorded in the channel list (step A32), and then the process proceeds to step A31. As described above, new channel addition processing is performed. As a result, a new channel can be added to the already created channel list.

  Further, the broadcast wave processing unit 25 (corresponding to the recording means) of the mobile device 1 (including the mobile devices 1 of the first to fourth modified examples) described above is provided with a broadcast area (further, a communication area, a mobile area, and a residence At least one of the areas and the like may be recorded on the removable storage medium 17a, and the control unit 5c (corresponding to the recording means) of the network server 5 described above may be a broadcast area (and further a communication area). , At least one of a moving area and a living area) may be recorded in the memory unit 5b in association with the mobile device ID information. Thereby, even when the user replaces the mobile device 1 (including the case of new replacement such as replacement by purchase or the case of using a plurality of mobile devices 1 properly), the broadcast area obtained in the past (further, Communication area, moving area, living area, etc.) can be reused. A channel list may be recorded in the recording medium 17a of the mobile device 1 or the memory unit 5b of the network server 5.

  Further, when the above-described mobile device 1 (including the mobile devices 1 of the first to fourth modified examples) can use an application such as FeliCa (registered trademark), this type of application is used to It is also possible to set the communication area registration timing (timing for adding the communication area registration frequency) when the ticket gate passes. Furthermore, the registration frequency of the communication area information, such as the timing at which it is detected that the mobile device 1 has passed the ticket gate, the timing at the start or end of broadcast reception, and the timing at which the mobile device 1 is turned on / off, It is possible to set a plurality of types of registration timing to be added, and when adding the registration frequency of communication area information, the number set for each of the plurality of types of registration timing (not only “1” but other than “1”) May be added to the registration frequency of the communication area information. For example, the number added to the registration frequency at the registration timing at the start of broadcast reception can be “10”, and the number added to the registration frequency at the registration timing when passing through the station ticket gate can be “3”. Thereby, it is possible to add the registration frequency according to the usage status of the mobile device 1.

  Further, the position information of the mobile device 1 corresponding to the position area information may be acquired using a GPS positioning method. As the GPS positioning method that can be used by the above-described mobile device 1 (including the mobile devices 1 of the first to fourth modifications), a GPS method and a multiple base station method can be used. The GPS method is a method of acquiring the position information of the mobile device 1 from the positioning result in the GPS module, and the multiple base station method is the position information of the mobile device 1 by combining the positioning result in the GPS module and the positioning result in the base station. It is a method to acquire. Further, a GPS positioning method called a cell-based method can also be used. The cell-based method is a method for acquiring position information of the mobile device 1 using cell information (base station information) of the base station 3 to which the mobile device 1 is connected. The mobile device 1 acquires the base station information from the base station 3 as latitude / longitude information. In this case, the mobile device 1 or the network server 5 stores in advance the table information in which the location information of the mobile device 1 acquired using the above-described GPS positioning method and the broadcast area information are associated with each other in the memory unit of the mobile device 1. 17 or in the memory unit 5b of the network server 5. By referring to this table information, the mobile device 1 or the network server 5 can easily identify the corresponding broadcast area from the location information of the mobile device 1 acquired using the GPS positioning method. By using such a GPS positioning method, highly accurate position positioning can be easily performed.

  Next, operations and effects of the communication system 100 according to the present embodiment will be described. A mobile device 1 capable of transmitting and receiving communication data via a base station 3 and receiving a plurality of broadcast waves, registers the communication area information of the base station 3 received from the base station 3, and stores the registered communication area information.

A channel scanning unit 251 to acquire, and a broadcast wave processing unit 25 to create a channel list based on broadcast information acquired by the channel scanning unit 251 The plurality of broadcast information having the same remote controller ID but different service IDs are acquired by the living area determination unit 255 in the plurality of broadcast information. If the same broadcast information as the broadcast information received in the broadcast area is included, a channel list is created based on this broadcast information. In areas where the broadcast areas overlap, a plurality of broadcast information can be used. However, the plurality of pieces of broadcast information may include a plurality of pieces of broadcast information having different service IDs but the same remote controller ID. In this regard, according to the mobile device 1, when a plurality of pieces of broadcast information having the same service ID but the same remote control ID are acquired, the broadcast area is specified according to the previously specified registration frequency. A channel list can be created based on broadcast information corresponding to an area. Therefore, a suitable channel list can be automatically created according to the movement status of the user (mobile device 1) even in an area where a plurality of broadcast areas overlap.

  In addition, the communication system 100 according to the second and fourth modifications includes a mobile device 1 that can transmit and receive communication data via the base station 3 and can receive a plurality of broadcast waves, and broadcast area information to the base station 3. A network server 5 for transmitting to the mobile device 1 via the base station 3, the network server 5 receives communication area information indicating the communication area of the base station 3 from the base station 3 and transmits the broadcast area information via the base station 3. The communication unit 5a to be transmitted to the mobile device 1 and the communication area information received by the communication unit 5a are registered, the registration frequency of the registered communication area information is counted for each communication area information, and the movement is performed based on the counted registration frequency.

When a plurality of pieces of broadcast information having the same remote control ID but different service IDs are acquired, the processing unit 25 indicates the broadcast area information received by the communication unit 13a in the plurality of pieces of broadcast information. If the same broadcast information as the broadcast information received in the broadcast area is included, a channel list is created based on this broadcast information. To. In areas where the broadcast areas overlap, a plurality of broadcast information can be used. However, the plurality of pieces of broadcast information may include a plurality of pieces of broadcast information having different service IDs but the same remote controller ID. In this regard, according to the communication system 100 according to the second and fourth modified examples, when a plurality of pieces of broadcast information having the same service ID but the same remote control ID are acquired, the registration frequency specified in advance is set. Accordingly, a broadcast area is specified, and a channel list can be created based on broadcast information corresponding to this broadcast area. Therefore, a suitable channel list can be automatically created according to the movement status of the user (mobile device 1) even in an area where a plurality of broadcast areas overlap. In addition, since the registration frequency of the communication area is counted not in the mobile device 1 but in the network server 5, the burden on the mobile device 1 is reduced.

If a plurality of pieces of broadcast information having different remote control IDs but different service IDs are acquired, If it contains the same broadcast information and broadcast information received by the broadcasting area specified by the area determining unit 255 creates a channel list based on the broadcast information. In areas where the broadcast areas overlap, a plurality of broadcast information can be used. However, the plurality of pieces of broadcast information may include a plurality of pieces of broadcast information having different service IDs but the same remote controller ID. In this regard, according to the communication system 100 according to the first and third modifications, when a plurality of pieces of broadcast information having the same service ID but the same remote control ID are acquired, the registration frequency specified in advance is set. Accordingly, a broadcast area is specified, and a channel list can be created based on broadcast information corresponding to this broadcast area. Therefore, a suitable channel list can be automatically created according to the movement status of the user (mobile device 1) even in an area where a plurality of broadcast areas overlap.

  Furthermore, in the communication system 100 (including the first to fourth modification examples), the living area determination unit 255 or the control unit 5c (first to fourth modification examples) is heavy depending on the elapsed time since registration. And the registration frequency is counted. In this way, since the registration frequency is counted with a weight that increases according to the elapsed time from the initial registration (for example, the initial registration), the period during which the communication terminal exists in a certain communication area ( How long it has existed in the past) will be appropriately reflected in the registration frequency.

  Furthermore, in the mobile device 1 (including the mobile devices 1 of the first to fourth modifications), the broadcast wave processing unit 25 has already created when the new broadcast information acquired by the channel scan unit 251 is acquired. The updated channel list may be updated based on the new broadcast information. As a result, a new channel can be added to the already created channel list.

  Furthermore, the mobile device 1 (including the mobile devices 1 of the first to fourth modifications) further includes a removable recording medium 17a, and the broadcast wave processing unit 25 stores the broadcast area information indicating the broadcast area as the recording medium. The channel list may be created using the broadcast area information recorded in the recording medium 17a. Thereby, even when the user exchanges the mobile device 1 (including the case of new replacement such as replacement by purchase or the case of using a plurality of mobile devices 1 properly), the broadcast area information obtained in the past is reused. it can.

  Furthermore, in the mobile device 1 (including the mobile devices 1 of the first to fourth modifications), the living area determination unit 255 responds to the type of registration timing at which the communication area information is registered when counting the registration frequency. A predetermined number may be added to the registration frequency. Thereby, it is possible to add the registration frequency according to the usage status of the mobile device 1.
