  The configuration and processing of the group subscription mobile device charging system according to an embodiment of the present invention will be described below.

  FIG. 1 is a block diagram showing a configuration of a group subscription mobile device billing system according to the present embodiment.

  The group subscription mobile device charging system according to the present embodiment includes grouped mobile devices (1 to 10), a base station 11, a mobile communication switching center (Visit Location Resister) 12, an HLR (Home Location Resister) 13, and a charging It has a server 14.

  Each of the mobile devices (1 to 10) performs wireless communication with the base station 11. The base station 11 is connected to a mobile communication switching center 12, and the mobile communication switching center 12 is connected to an HLR 13 provided for each predetermined area.

  The mobile communication switching center 12 performs call processing control, authentication location registration control, and radio control, and controls outgoing / incoming connections in the mobile devices (1 to 10).

  The base station 11 relays information communication between the mobile communication switching center 12 and the mobile station (1 to 10) by controlling the control channel and the communication channel set for the antenna. The mobile devices (1 to 10) are used as subscriber communication terminals in areas where mobile radio communication is possible with base stations provided in various places.

  The mobile devices (1 to 10) are groups in which 10 mobile devices are set for five line contracts, and outgoing / incoming calls in the group are managed as five mobile devices. In addition, the HLR 13 to which the mobile device (1 to 10) belongs includes a use state storage memory in which the current use state of the call channel of the mobile device (1 to 10) is written, and the connection state of the mobile device (1 to 10). The first to fifth memory units to be monitored are included. When any one of the mobile devices (1 to 10) is connected by calling / receiving, the use state storage memory stores that fact in any of the first to fifth memory units. At this time, the connection status is stored as “empty = 0” and “in use = 1”. Further, the use state storage memory includes a subscriber ID for identifying the subscriber, a password required for the subscriber when changing the number of simultaneous connections, a mobile unit number that is a number unique to each mobile unit, and outgoing and incoming calls of each mobile unit Incoming and outgoing call information including a history and a communication result of each history (in this embodiment, information indicating whether or not outgoing call from the mobile device or incoming call to the mobile device is connected) is stored.

  When the mobile station (1 to 10) makes / receives a call, the mobile switching center 12 checks the information stored in the use state storage memory, and performs connection for outgoing / incoming calls by the number of memory units in which “0” is stored. . In the present embodiment, the maximum number of simultaneous connections for outgoing / incoming calls of mobile devices (1 to 10) is limited to five.

  Next, the connection at the time of outgoing / incoming call of the group subscription mobile device billing system according to the present embodiment will be described with reference to FIG.

  First, when there is a call from the mobile device 1 (including the mobile device number), the mobile switching center 12 receives the call via the base station 11 (step S401), and the mobile device 1 belongs based on the mobile device number. The HLR 13 is determined (step S402). When the HLR 13 is determined, the mobile switching center 12 accesses the HLR 13 (step S403) and confirms the states of the first to fifth memory units in the group to which the mobile device 1 belongs (step S404).

  Here, it is determined whether or not “0” is stored in any of the first to fifth memory units (step S405). When “0” is stored in any of the first to fifth memory units (step S405 / YES), the mobile communication switching center 12 performs the connection process of the mobile device 1 (step S406). When the mobile device 1 is connected, the HLR 13 rewrites one of the memory units in which “0” of the first to fifth memory units of the use state storage memory is stored from “0” to “1”, The usage status information part of the usage status storage memory of the mobile device 1 is rewritten from “0” to “1” (step S407). Further, it is stored in the use state storage memory as outgoing / incoming information of the mobile device 1 (step S408). If “0” is not stored in any of the first to fifth memory units, the mobile communication switching center 12 performs a disconnection process on the mobile device 1 (step S409). Even when the transmission from the mobile device 1 is disconnected, it is stored in the use state storage memory as outgoing / incoming information from the mobile device 1 (step S408).

  Next, processing when the call by the mobile device 1 is finished will be described with reference to FIG.

  When the call of the mobile device 1 is completed (step S501), the mobile switching center 12 notifies the HLR 13 to that effect (step S502). Upon receiving the notification, the HLR 13 rewrites one of the first to fifth memory units of the use state storage memory to which the mobile device 1 belongs, for example, the first memory unit from “1” to “0”, and the mobile device 1 The usage status information part of the usage status storage memory is rewritten from “1” to “0” (step S503). As a result, any of the other mobile devices that wish to communicate can be made / received. In addition, when outgoing / incoming information including the outgoing / incoming call history is added to the outgoing / incoming information while a call is being made by the mobile device 1, the outgoing / incoming call is disconnected based on the outgoing / incoming history. The machine is notified that communication is possible (step S504).

  Next, processing when receiving an incoming call to the mobile device will be described with reference to FIG.

  For example, when the mobile communication switching center 12 receives an incoming call to the mobile device 2 (step S601), the mobile communication switching center 12 determines the HLR 13 to which the mobile device 2 belongs (step S602). When the HLR 13 is determined, the mobile switching center 12 accesses the HLR 13 (step S603) and checks the states of the first to fifth memory units of the group to which the mobile device 2 belongs (step S604). Then, it is determined whether or not “0” is stored in any of the first to fifth memory units (step S605). When any one of the first to fifth memory units is “0” (step S605 / YES), the mobile switching center 12 performs a connection process to the mobile device 2 (step S606). When the mobile device 2 is connected, the HLR 13 rewrites any of the first to fifth memory units of the usage state storage memory to which the mobile device 2 belongs from “0” to “1”, and the usage status of the mobile device 2 The usage state information part of the storage memory is rewritten from “0” to “1” (step S607). Further, the outgoing / incoming information of the mobile device 2 is stored in the use state storage memory (step S608).

  If “0” is not stored in any of the first to fifth memory units (step S605 / NO), the mobile communication switching center 12 disconnects the incoming call to the mobile device 2 (step S609). . Even when the incoming call to the mobile device 2 is disconnected, the outgoing / incoming information of the mobile device 2 is stored in the use state storage memory (step S608).

  When communication in the mobile device (1 to 10) is completed and any one of the first to fifth memory units is stored as “0”, the mobile communication switching center 12 notifies the HLR 13 to that effect. Receiving the notification, the HLR 13 rewrites the first to fifth memory units storing the communication state of the mobile device (1 to 10) whose communication has been completed from “1” to “0”, and the communication is completed. The usage status information part of the usage status storage memory of the mobile device is rewritten from “1” to “0”. As a result, any of the other mobile devices that wish to communicate can be made / received. Then, when the incoming / outgoing call information to / from the mobile station (1 to 10) is stored in the use state storage memory, the mobile station (1 to 10) is sent to the mobile station (1 to 10). The mobile device that has made a call, the mobile device that has received the incoming call (1 to 10), and the mobile device that wants to make a call (1 to 10) are notified that communication is possible.

  As a result of the above processing, the number of simultaneous connections of the mobile devices (1 to 10) is limited to five based on the states of the first to fifth memory units of the use state storage memory.

  Next, an operation for changing the number of simultaneous connections will be described with reference to FIG.

  First, when a signal for requesting a change in the number of simultaneous connections (hereinafter referred to as a connection number change signal) is transmitted by the subscriber using the mobile device (1 to 10) (step S701), the mobile switching center 12 Receives the transmission via the base station 11, and determines the HLR 13 to which the mobile station that transmitted the signal belongs based on the mobile station number (step S702). At the same time, the mobile switching center 12 requests the mobile station (1 to 10) that has transmitted the connection number change signal to transmit the subscriber ID and password (step S703).

  Upon receiving the subscriber ID and password from the mobile device (1 to 10) from which the HLR 13 has been determined and the connection number change signal has been transmitted, the mobile switching center 12 accesses the HLR 13 (step S704), and the mobile switching center 12 compares the subscriber ID and password stored in the use state storage memory with the subscriber ID and password received from the mobile device (1 to 10) (step S705). If the mobile communication switching center 12 does not match, the mobile communication switching center 12 rejects the change in the number of simultaneous connections (step S711). On the other hand, if the two match (step S705 / YES), the mobile switching center 12 requests the mobile station to transmit the desired number of simultaneous connections (step S706). When the desired number of simultaneous connections is received from the mobile device, the mobile communication switching center 12 checks the states of the first to fifth memory units of the group to which the mobile device belongs (step S707).

  Here, it is determined whether or not the number of memory units storing “1” among the first to fifth memory units is larger than the number of simultaneous connections desired from the mobile device (1 to 10) (step 708). ). When the number of memory units storing “1” among the first to fifth memory units is larger than the number of simultaneous connections desired from the mobile device (1 to 10) (step S708 / YES), The mobile communication switching center 12 refuses to change the number of simultaneous connections (step S711). On the other hand, when the number of memory units storing “1” among the first to fifth memory units is smaller than the number of simultaneous connections desired from the mobile device (1 to 10) (step S708 / NO). The mobile communication switching center 12 requests the HLR 13 to change the number of memory units (step S709). When the HLR 13 receives a request to change the number of memory units from the mobile switching center 12, the HLR 13 provides the same number of memory units as the number of simultaneous connections desired from the mobile devices (1 to 10) (step S710).

  Through the above processing, the subscriber can change the number of simultaneous connections as required. In addition, when accepting a request for changing the number of simultaneous connections, by requesting the mobile station that sent the connection number change signal to enter the subscriber ID and password, the number of unauthorized simultaneous connections by a third party other than the subscriber Can be prevented.

  Next, the operation of the billing server 14 that charges the subscriber a line usage fee according to the number of simultaneous connections set by the subscriber will be described.

  The billing server 14 stores the subscriber ID stored in the use state storage memory, the change history of the number of memory units classified for each subscriber ID, and the number of memory units (number of simultaneous connections) corresponding to each change history. It has a storage unit for storing.

  The change history is added to the storage unit in response to a notification from the HLR 13 every time the number of memory units for each subscriber is changed in the HLR 13. The billing server 14 determines the line usage fee for the subscriber according to the change history stored in the storage unit and the number of simultaneous connections corresponding to the change history.

  Specifically, the line usage fee for the subscriber is determined through the following processing shown in FIG.

  The HLR 13 notifies the accounting server 14 that the processing for changing the number of memory units has been performed at the same time that the number of memory units is changed (step S801). At that time, the HLR 13 also notifies the charging server 14 of the subscriber ID of the subscriber whose number of memory units has been changed. The accounting server 14 that has received the notification that the change processing has been performed accesses the HLR 13 and acquires information regarding the number of memory units after the change based on the notified subscriber ID (step S802). The accounting server 14 that has acquired the information on the number of memory units after the change classifies them into subscriber IDs, and stores the number of memory units together with the change history in the storage unit (step S803).
