Description

  The present invention defines a communication terminal as a parent among a plurality of communication terminals capable of short-range communication with each other, and the parent terminal represents a single communication terminal and communicates with another communication terminal (hereinafter referred to as a child terminal). The present invention also relates to a wireless communication system that communicates with an external network.

Third-generation (3G) mobile phone system “W (Wideband: Wideband) -CDMA (Code Division Multiple Access)” data communication speed-up standards include HSDPA (High Speed Uplink Packet Access) and There is HSUPA (High Speed Downlink Packet Access). HSDPA is a technology that improves the packet communication speed in the downstream (base station to terminal) direction, and HSUPA is a technology that improves the packet communication speed in the upstream (terminal to base station) direction. (Packet Access).
In addition, there is a standard called Super3G (S3G) as a further evolution of the high-speed data communication standard “HSPA” of the third generation mobile phone system “W-CDMA”.

  High-speed wireless communication based on these high-speed data communication standards such as HSDPA, HSUPA, and S3G is a service of a best effort type (communication network without guarantee of quality of service (QoS)) using a shared channel. For this reason, as the number of communication terminals (users) connected to the communication network increases, the individual throughput decreases when a plurality of users perform data communication simultaneously. In addition, the shared channel is shared by the user as a single physical channel for the entire bandwidth of 5 MHz width, and all the available bandwidth can be used effectively, and requires multiple voices and data using time multiplexing and code multiplexing. Bandwidth is allocated to the user.

  In particular, even when multiple users handle the same payload data in the same area, use wireless bands wastefully to secure bandwidth (resources) in the shared channel for each user individually. There is a problem of end. In the same area, when multiple users handle the same payload data, for example, when children gather together to play a network game, or when the same content (movie, etc.) is downloaded in a community such as a family is assumed.

  On the other hand, when using a network application such as chat using a communication terminal, a conventional communication system uses a single communication terminal as a base unit and a wireless link function of the communication terminal, so that a plurality of communication terminals Are linked locally (see, for example, Patent Document 1).

  In the conventional wireless LAN system, each transmission / reception means is controlled so as to switch between the first state at the normal time and the second state at the time of control transfer. Then, when a control delegation reason to any of the child communication devices occurs in the first state, a control delegation signal that permits the transmission / reception means of the child communication device to be turned on is sent from the parent communication device to each near field communication device. To the child communication device. Thus, switching to the second state is performed (see, for example, Patent Document 2).

  Moreover, the temporary parent determination method of the conventional wireless conference system is that the wireless terminal stores the terminal information storage unit that stores the terminal information of the terminal itself, and the other terminal information storage that temporarily stores the terminal information transmitted from the other wireless terminal. And a base unit determining unit that determines a wireless terminal suitable for becoming a temporary parent based on the stored terminal information. The parent device determination unit determines a temporary parent based on specific information from terminal information such as transmission power, battery information, and network address information (see, for example, Patent Document 3).

Japanese Patent Laid-Open No. 2001-244928 Japanese Patent No. 3759928 JP-A-11-146030

  However, in the temporary parent determination method of the conventional communication system, wireless LAN system, and wireless conference system, the number of slave units (slave communication devices) that follow the master unit (parent communication device) cannot be recognized on the network side. For this reason, in a conventional communication system or the like, billing relating to a carrier line usage fee (hereinafter referred to as a line usage fee) and a content usage fee (hereinafter referred to as a content usage fee) can be performed only for the parent device. There is a problem.

  In addition, since it is possible to reduce the bandwidth that should be originally allocated to the slave unit in the common channel by making the slave unit follow the master unit, the master unit reduces the bandwidth usage rate in the shared channel the more slave units it can follow. Contribute to. However, in a conventional communication system or the like, even if the number of slave units that can follow the master unit can be recognized on the network side, the shared channel bandwidth is reflected in the number of slave units that follow the master unit. However, there is a problem that there is no return in return for reducing the share of the shared channel.

  The wireless communication system determines one parent terminal according to the wireless quality of each communication terminal among a plurality of communication terminals requesting the same content, and groups communication terminals other than the parent terminal as child terminals. A communication terminal group is provided. In addition, the wireless communication system includes a wireless control server that allocates a bandwidth in a shared channel to the parent terminal when downloading content data from the application server that provides the content to the parent terminal. The parent terminal transmits the terminal information of the own terminal and the terminal information of the child terminal acquired from the child terminal to the radio control server, receives content data from the radio control server, and sends the content data to the child terminal. Send. Also, the radio control server allocates a band in the shared channel for the parent terminal based on the terminal information transmitted from the parent terminal, and transmits the content data to the parent terminal.

  The disclosed wireless communication system can allocate a bandwidth according to the number of child terminals that can be followed by the parent terminal in the shared channel to the parent terminal, and can use a line for all the communication terminals of the parent terminal and the child terminals. There is an effect that it is possible to perform billing related to the fee and the content usage fee.

  Next, a processing procedure in the wireless communication system according to the present embodiment will be described with reference to FIGS. In the following description, three communication terminals 10 that request the same content will be described as an example. In addition, it is assumed that the three communication terminals 10 are in the same cell, and the communication terminals 10 exist within a short-range wireless communication area.

  First, a process of determining one parent terminal 10a among the three communication terminals 10 will be described with reference to FIGS. In the following description, since the three communication terminals 10 perform the same processing operation, the three communication terminals 10 will be described without distinction.

  The user operates the input unit 1 of the communication terminal 10 to select desired content displayed on a display unit (not shown) (step S1), and the input unit 1 outputs selection information to the application unit 7 (step S1). S2).

The application unit 7 activates the representative terminal download service based on the selection information input from the input unit 1 (step S3).
The application unit 7 outputs a request for establishing a link with another communication terminal 10 (hereinafter referred to as an inter-terminal link establishment request) to the short-range communication unit 2 (step S4). Wait for an agreement (response) to the link establishment request between terminals.

The short-range communication unit 2 receives the inter-terminal link establishment request input from the application unit 7, and transmits the inter-terminal link establishment request to the other communication terminals 10 (step S5). The short-range communication unit 2 receives a response from the other communication terminal 10 (step S6), establishes a link with the other communication terminal 10 (step S7), and establishes a link with the other communication terminal 10. The establishment is notified to the application unit 7 (step S8).
The application unit 7 reads radio quality information from the radio quality status management unit 4 based on the notification from the short-range communication unit 2 (step S9).

  In addition, the application unit 7 outputs a wireless quality information exchange request (wireless quality information of its own terminal) to another communication terminal 10 to the short-range communication unit 2 (step S10), and a response from the other communication terminal 10 Wait for (wireless quality information of other terminals).

  Upon receiving the wireless quality information exchange request (the wireless quality information of the own terminal) input from the application unit 7, the short-range communication unit 2 receives the wireless quality information exchange request (of the own terminal) from the other communication terminal 10 (Radio quality information) is transmitted (step S11). Further, the short-range communication unit 2 receives a response (radio quality information of another terminal) from another communication terminal 10 (step S12), exchanges radio quality information with the other communication terminal 10, The wireless quality information of the communication terminal 10 is output to the application unit 7 (step S13).

  When the wireless quality information of the other communication terminal 10 is input from the short-range communication unit 2, the application unit 7 receives the wireless quality information of the own terminal acquired from the wireless quality status management unit 4 and the other communication terminal 10. The wireless quality information of the other terminal is compared to determine whether or not the wireless quality of the terminal itself is the best (step S14).

  If it is determined in step S14 that the wireless quality of the terminal is the best, the application unit 7 determines that the terminal is the parent terminal 10a, and transitions the terminal to the parent terminal 10a (step S15).

  If it is determined in step S14 that the wireless quality of the terminal itself is not the best, the application unit 7 determines that the terminal is the child terminal 10b, and transitions the terminal to the child terminal 10b (step S16).

Through the above processing, one parent terminal 10a among the plurality of communication terminals 10 can be determined.
Next, processing in which the parent terminal 10a requests content instead of the two child terminals 10b on behalf of the communication terminal group will be described with reference to FIGS. In the following description, “a” is added to the end of the code of each block in the parent terminal 10a, and “b” is added to the end of the code of each block in the child terminal 10b. Further, in the following description, since the two child terminals 10b have the same processing operation, the two child terminals 10b will be described without distinction.

  When the communication terminal 10 transitions to the parent terminal 10a, the application unit 7a of the parent terminal 10a reads the terminal information of the own terminal (parent terminal 10a) from the terminal information storage unit 5a, and the terminal information of the own terminal (parent terminal 10a). Is held (step S101).

  The application unit 7a of the parent terminal 10a outputs a terminal information reading request (hereinafter referred to as a terminal information acquisition request) from the child terminal 10b from the child terminal 10b to the short-range communication unit 2a (step S102). Wait for a response (terminal information) from the child terminal 10b.

  Upon receiving the terminal information acquisition request input from the application unit 7a, the short-range communication unit 2a of the parent terminal 10a transmits a terminal information acquisition request to the child terminal 10b in order to obtain the terminal information of the child terminal 10b (step S103).

  Upon receiving the terminal information acquisition request from the parent terminal 10a (step S104), the short-range communication unit 2b of the child terminal 10b outputs the terminal information acquisition request to the application unit 7b (step S105).

  The application unit 7b of the child terminal 10b receives the terminal information acquisition request input from the short-range communication unit 2b, and reads the terminal information of the own terminal (child terminal 10b) from the terminal information storage unit 5b (step S106).

  And the application part 7b of the child terminal 10b outputs the terminal information of the own terminal (child terminal 10b) read from the terminal information storage part 5b to the near field communication part 2b (step S107).

  The near field communication unit 2b of the child terminal 10b transmits the terminal information of the own terminal (child terminal 10b) input from the application unit 7b to the near field communication unit 2a of the parent terminal 10a (step S108).

  When the short-range communication unit 2a of the parent terminal 10a receives the terminal information of the child terminal 10b from the child terminal 10b (step S109), it outputs the terminal information of the child terminal 10b to the application unit 7a (step S110).

When the application unit 7a of the parent terminal 10a acquires the terminal information of the child terminal 10b from all the child terminals 10b, a request for establishing a link with the radio control server 110 is made to the long-distance wireless communication unit 3a (hereinafter, referred to as “the terminal”). The mobile wireless link establishment request is output (step S111). Note that terminal information of the parent terminal 10a and the child terminal 10b in the grouped communication terminals is added to the portable wireless link establishment request.
The long-distance wireless communication unit 3a of the parent terminal 10a transmits a portable wireless link establishment request input from the application unit 7a to the wireless control server 110 (step S112).

Through the above processing, the parent terminal 10a can request content instead of the two child terminals 10b on behalf of the communication terminal group.
Next, processing on the network side of the carrier core network 100 and the external network 200 will be described with reference to FIGS.

  When the wireless control server 110 receives the mobile wireless link establishment request (including terminal information) from the communication terminal 10 (step S201), the subscriber authentication unit 111 determines whether the child authentication link 111 is based on the terminal information included in the mobile wireless link establishment request. It is determined whether or not the access is from the communication terminal 10 (parent terminal 10a) following the terminal 10b (step S202). That is, the subscriber authentication unit 111 determines whether the terminal information received from the communication terminal 10 is a plurality of terminal information.

  If it is determined in step S202 that the access is from the parent terminal 10a followed by the child terminal 10b, the subscriber authentication unit 111 sends a mobile radio link establishment request to which the terminal information of the parent terminal 10a and the child terminal 10b is added. And transmitted to the gateway server 140 (step S203a).

  When the gateway server 140 receives the mobile radio link establishment request from the radio control server 110 (step S204a), the gateway server 140 requests authentication of whether the parent terminal 10a and the child terminal 10b are subscribers of its own carrier (hereinafter referred to as terminal subscriber authentication request). Is transmitted to the subscriber information management server 120 (step S205a).

  When the subscriber information management server 120 receives the terminal subscriber authentication request from the gateway server 140 (step S206a), the subscriber information management server 120 compares the managed subscriber information with the terminal information of the parent terminal 10a and the child terminal 10b, and determines the parent terminal 10a. And the child terminal 10b are authenticated as to whether they are subscribers of the own carrier (step S207a).

  Then, the subscriber information management server 120 transmits the authentication result of the parent terminal 10a and the child terminal 10b in response to the terminal subscriber authentication request to the radio control server 110 via the gateway server 140 (step S208a).

  When the subscriber authentication unit 111 of the wireless control server 110 receives the authentication result transmitted from the gateway server 140 (step S209a), all of the parent terminal 10a and the child terminal 10b are subscribers of their own carriers based on the authentication result. Is determined (step S210a).

  In step S210a, when it is determined that the parent terminal 10a and the child terminal 10b include the communication terminal 10 that is not a subscriber of the own carrier, the subscriber authentication unit 111 includes an error indicating that the communication terminal 10 is not a subscriber of the own carrier. A notification is transmitted to the parent terminal 10a (step S211a).

  In step S210a, when it is determined that all the subscribers are subscribers, the subscriber authentication unit 111 assigns the bandwidth in the shared channel to the parent terminal 10a to which information on the number of child terminals 10b according to the parent terminal 10a is added. The request is output to the shared channel resource information determination unit 112 (step S212a).

  The shared channel resource information determination unit 112 determines the occupancy rate of the shared channel with respect to the parent terminal 10a based on the number information of the child terminals 10b input from the subscriber authentication unit 111 (step S213a). Further, the shared channel resource information determination unit 112 outputs information on the determined share channel occupancy to the shared channel resource allocation control unit 113 (step S214a). Note that the share channel share ratio is proportional to the share channel share ratio for the communication terminal 10 that cannot follow the child terminal 10b, for example, in proportion to the number of child terminals 10b that follow the parent terminal 10a. It is conceivable that the channel occupation rate is multiplied by an integer.

  The shared channel resource allocation control unit 113 allocates a bandwidth in the shared channel to the parent terminal 10a based on the shared channel occupancy rate information input from the shared channel resource information determination unit 112 (step S215a). A portable radio link with the radio control server 110 is established (step 216a).

  Then, the wireless control server 110 requests the application server 210 that stores the content requested by the communication terminal 10 via the gateway server 140, which is an existing operation, to transmit the content data of the content (step S217a). .

  In response to a request from the communication terminal 10, the application server 210 starts downloading desired content data to the parent terminal 10a via the gateway server 140 and the wireless control server 110 (step S218a). In this case, the content data is transmitted to the parent terminal 10a according to the band in the shared channel for the parent terminal 10a assigned by the shared channel resource assignment control unit 113 of the radio control server 110 (step S219a).

  In addition, the line usage fee billing request unit 114 of the wireless control server 110 performs a line usage fee billing process for each of the parent terminal 10a and the child terminal 10b via the gateway server 140, which is an existing operation. Request to 130 (S220a).

  The charging management server 130 charges the line usage fee for each communication terminal 10 of the parent terminal 10a and the child terminal 10b in response to the charging processing request from the line usage fee charging request unit 114 of the wireless control server 110. (Step S221a). In this case, it is conceivable that the charge for the line usage fee for each child terminal 10b is charged uniformly to the parent terminal 10a and the child terminal 10b, for example, as the same amount as the charge for the line usage fee for the parent terminal 10a. It is also possible to apply a group discount or the like that lowers the charging coefficient for the parent terminal 10a and the child terminal 10b as the number of child terminals 10b that can follow the parent terminal 10a increases.

  When the application server 210 finishes transmitting all the content data in the content requested from the parent terminal 10a to the parent terminal 10a, the application server 210 ends the download of the content data (step S222a).

  In addition, the charging management server 130 performs content usage fee charging processing for each communication terminal 10 of the parent terminal 10a and the child terminal 10b (step S223a). In this case, the content usage fee for each child terminal 10b may be charged uniformly to the parent terminal 10a and the child terminal 10b, for example, as the same amount as the content usage fee for the parent terminal 10a. It should be noted that the content usage fee may be charged by applying a group discount or the like that lowers the charging coefficient for the parent terminal 10a and the child terminal 10b as the number of child terminals 10b following the parent terminal 10a increases.

  Then, when the download of the content data, the charging of the line usage fee, and the charging of the content usage fee are completed, the wireless control server 110 releases the mobile wireless link with the parent terminal 10a (step S224a).

  If it is determined in step S202 described above that the access is not from the parent terminal 10a, as shown in FIGS. 7 to 9, the process corresponds to step S203a to step S224a, step S203b to step S224b. Detailed description is omitted. Note that in steps S203b to S224b, the parent terminal 10a and the child terminal 10b that are subject to subscriber authentication, bandwidth allocation in the shared channel, and line usage fee and content usage fee are not subject to the child terminal 10b. The communication terminal 10 is a target.

  Next, the processing until the parent terminal 10a acquires content data instead of the two child terminals 10b on behalf of the communication terminal group and distributes the content data to the child terminal 10b is shown in FIG. 11 and FIG. It explains using.

  In step S216a described above, a portable wireless link with the network is established, download starts in step 218a, and the long-distance wireless communication unit 3a of the parent terminal 10a receives the content data transmitted from the wireless control server 110 in step S219a. (Step S301). Then, the long-distance wireless communication unit 3a of the parent terminal 10a outputs the received content data to the application unit 7a (step S302).

The application unit 7a of the parent terminal 10a stores the content data input from the long-distance wireless communication unit 3a in the data storage unit 6a (step 303).
When the application unit 7a of the parent terminal 10a finishes downloading the content data transmitted from the radio control server 110 (steps S304 and S221a), the application unit 7a reads the content data stored in the data storage unit 6a (step S305).

  The application unit 7a of the parent terminal 10a notifies the short-range communication unit 2a of a content distribution request to the child terminal 10b together with the content data read from the data storage unit 6a (step S306).

  The near field communication unit 2a of the parent terminal 10a transmits the content data input from the application unit 7a to the near field communication unit 2b of the child terminal 10b based on the distribution request from the application unit 7a (step S307).

  When the short-range communication unit 2b of the child terminal 10b receives the content data from the parent terminal 10a (step S308), it outputs the content data to the application unit 7b (step S309).

The application unit 7b of the child terminal 10b stores the content data input from the short-range communication unit 2b in the data storage unit 6b (step S310).
When all the content data is stored in the data storage unit 6b, the child terminal 10b ends the representative terminal download service (step S311).

  When the parent terminal 10a completes the transmission of the content data to all the child terminals 10b, the master terminal 10a ends the representative terminal download service (step S312), and releases the mobile wireless link with the radio control server 110 (step S313). Step S224a).

  As described above, the wireless communication system according to the present embodiment has a shared channel for the parent terminal 10a according to the number of child terminals 10b that the parent terminal 10a can follow compared to the communication terminal 10 that cannot follow the child terminal 10b. By increasing the occupancy rate, content data can be downloaded comfortably. Thereby, the radio | wireless communications system which concerns on this embodiment has an effect that the parent terminal 10a can be given a return that is commensurate with the reduction in the occupancy rate of the shared channel by the slave terminal 10b.

  In addition, the wireless communication system according to the present embodiment has the effect of being able to charge not only the parent terminal 10a but also the child terminal 10b to which the parent terminal 10a follows, in connection with the line usage fee and the content usage fee. Play.

  In addition, the wireless communication system according to the present embodiment, in a best effort service using a wireless shared channel such as HSDPA, HSUPA or S3G, a plurality of users logically share the wireless band, There is an effect that it can be effectively used.

  In the wireless communication system according to the present embodiment, the case where the short-range communication unit 2 is compatible with short-range wireless communication has been described, but the case where the wireless communication system is compatible with wired communication is the same as the parent terminal 10a. Grouping is performed with the child terminal 10b, and the above-described processing is performed.

  In the radio communication system according to the present embodiment, one parent terminal 10a is determined according to the radio quality of each communication terminal 10 among the plurality of communication terminals 10 during grouping. It is not limited to the method. For example, among a plurality of communication terminals 10 that request the same content, the communication terminal 10 that has selected the content first, the communication terminal 10 that is subscribed to the carrier with the lowest line usage fee, or the communication that has the highest processing speed. It is conceivable that the terminal 10 or the like is the parent terminal 10a.

  Further, in the wireless communication system according to the present embodiment, the case where the parent terminal 10a in the communication terminal group downloads content on behalf of the communication terminal group has been described. However, the parent terminal 10a represents data on the application server 210 and uploads the data. May be.

  Furthermore, in the wireless communication system according to the present embodiment, if communication terminals 10 requesting the same content that subscribes to the own carrier gather, the desired content can be downloaded by grouping. You may only be able to download.

  Specifically, group information (for example, family discounts, etc.) consisting of a plurality of communication terminals 10 predetermined in a contract with a carrier is registered in the subscriber information management server 120, and in step S208a described above, The group information is read and transmitted together with the authentication result. In step S210a described above, it is determined whether all of the parent terminal 10a and the child terminal 10b are subscribers of the own carrier, and all of the parent terminal 10a and the child terminal 10b belong to a common group. Determine whether or not. If the user does not belong to the common group, the process proceeds to step S211a described above, and the subscriber authentication unit 111 transmits an error notification indicating that the user does not belong to the common group to the parent terminal 10a.

  Further, in the wireless communication system according to the present embodiment, the shared channel resource information determination unit 112 determines the occupancy rate of the shared channel for the parent terminal 10a according to the number of child terminals 10b that the parent terminal 10a can follow. However, it may be determined according to the contract form with the carrier.

  Specifically, information on the contract form (for example, contract plan, fixed amount / pay-for-use system, etc.) of each communication terminal 10 determined in advance by a contract with the carrier is registered in the subscriber information management server 120 and described above. In step S208a, the contract form information of each communication terminal 10 is read and transmitted together with the authentication result. In step S213a described above, based on the contract form information of the parent terminal 10a and the child terminal 10b read from the subscriber information management server 120, the occupation rate of the shared channel for the parent terminal 10a is determined. As a result, in the wireless communication system according to the present embodiment, the occupancy rate of the shared channel assigned to the parent terminal 10a by the carrier core network 100 side is determined by the contract form in all the communication terminals 10 of the parent terminal 10a and the child terminal 10b. There is an effect of being able to.

  Further, in the wireless communication system according to the present embodiment, even when content data is being downloaded, the share channel occupancy rate is changed in response to the new subscription or withdrawal of the child terminal 10b according to the parent terminal 10a. Alternatively, charging may be collected or stopped for the newly joined or withdrawn child terminal 10b.

  Specifically, the application unit 7a of the parent terminal 10a monitors the new participation and withdrawal of the child terminal 10b via the short-range communication unit 2a even when the content data is being downloaded. Then, triggered by the new subscription or withdrawal of the child terminal 10b, the application unit 7a of the parent terminal 10a notifies the radio control server 110 of the new subscription or withdrawal of the child terminal 10b via the long-distance wireless communication unit 3a.

  Then, the subscriber authentication unit 111 of the radio control server 110 subscribes the terminal information of the child terminal 10b that has been changed via the gateway server 140 in order to perform subscriber authentication of the newly joined or withdrawn child terminal 10b. The person information management server 120 is notified. In addition, the charge management server 130 charges the line usage fee to the newly joined child terminal 10b, and stops charging the line usage fee to the withdrawn child terminal 10b. Further, the shared channel resource information determination unit 112 of the radio control server 110 changes the occupancy rate of the shared channel for the parent terminal 10a according to the number of changed child terminals 10b as subscribers, and allocates shared channel resource allocation. The control unit 113 is requested to change the bandwidth in the shared channel. As a result, the wireless communication system according to the present embodiment allows the bandwidth in the shared channel for the parent terminal 10a and the parent terminal to increase or decrease in the number of child terminals 10b that the parent terminal 10a follows even during the content data download process. There is an effect that it is possible to change the charging process for 10a and the child terminal 10b.

  Further, in the wireless communication system according to the present embodiment, individual authentication may be performed from the wireless control server 110 to the child terminal 10b in order to prevent forgery of terminal information of the child terminal 10b by the parent terminal 10a.

  Specifically, when it is determined in step S210a described above that all of the parent terminal 10a and the child terminal 10b are subscribers of the own carrier, before proceeding to step S212a described above, the following processing shown in FIG. Will do.

  The subscriber authentication unit 111 of the wireless control server 110 individually receives a subscriber authentication confirmation request (hereinafter referred to as an individual authentication confirmation request) by mobile wireless communication to each child terminal 10b that is determined to be a subscriber of the own carrier. Is transmitted) (step S401).

  When the long-distance wireless communication unit 3b of the child terminal 10b receives the individual authentication confirmation request from the wireless control server 110, it notifies the application unit 7b of the individual authentication confirmation request (step S402). If the application unit 7b of the child terminal 10b is a communication terminal 10 that belongs to a communication terminal group under the control of the parent terminal 10a and uses the same download data, the application unit 7b recognizes the approval for the individual authentication confirmation request over a long distance. The data is output to the wireless communication unit 3b (step S403). The long-distance wireless communication unit 3b of the child terminal 10b transmits an approval for the individual authentication confirmation request to the wireless control server 110 (step S404).

  When the subscriber authentication unit 111 of the wireless control server 110 receives the approval for the individual authentication confirmation request from all the child terminals 10b determined to be subscribers of the own carrier, the process proceeds to step S212a described above. Note that the subscriber authentication unit 111 of the wireless control server 110 proceeds to step S211a described above when the approval for the individual authentication confirmation request cannot be received from all the child terminals 10b determined to be subscribers of the own carrier. Then, the subscriber authentication unit 111 transmits an error notification indicating that the child terminal 10b cannot be authenticated to the parent terminal 10a. As a result, it is possible to confirm whether or not the parent terminal 10a has illegally transmitted the terminal information (number) of the child terminal 10b to the carrier core network 100 side, and the authentication is performed more than the number of child terminals 10b that can be actually followed. Thus, there is an effect that it is possible to prevent misuse of increasing the occupancy rate of the shared channel.
