  FIG. 4 shows a configuration example of a mobile phone system in which the base station apparatus of the present invention shown in FIGS. 1 and 3 is installed in each radio base station. In this configuration, all of the radio base stations 101 to 104 have a function of relaying signals for original mobile phone communication, and the base station apparatuses of the radio base stations 101, 103, and 104 have the second function described in FIG. A control unit is provided, and a telephone number is given to each. Hereinafter, the telephone numbers given to the radio base stations 101, 103, and 104 are “090-1234-5671”, “090-1234-5673”, and “090-1234-5675”, respectively. These telephone numbers are assumed to be registered in the radio network controller as terminals located in the service area of each radio base station. A monitor camera 1011 as an external device is connected to the wireless base station 101, a control device 1031 as an external device and monitor cameras 1032 and 1033 controlled via the control device are connected to the wireless base station 103, and The wireless base station 104 is connected with a control device 1041 as an external device, an air conditioner 1042 and an indoor lamp 1043 controlled via this control device.

  The USIM card installed in the USIM unit of the base station apparatus of the radio base stations 101, 103, 104 includes, for example, identification information of the USIM card, external device, in addition to the telephone number given to the radio base station. The administrator information of the connection function part, the connection number to the function part, the device control information of the camera connected to the external device connection function part, etc. are recorded, and the communication time, fee, call history etc. It may be recorded at the time of use.

  Hereinafter, the operation of the apparatus of the present invention will be described using the cellular phone system of FIG. FIG. 5 is a flowchart showing the operation of the second controller 1532. When the mobile phone terminal 1012 located in the service area of the wireless base station 101 captures and monitors the image of the monitor camera 1032 installed in the wireless base station 103, the mobile phone terminal 1012 first calls the telephone of the wireless base station 103. Call the number "090-1234-5673". This call signal is sent to the radio network control apparatus 201 via the radio base station 101, and the radio network control apparatus 201 checks the location registration information of the called telephone number. Yes, since this is registered within the service area of the radio base station 103, the radio network controller 201 transmits a call signal to the radio base station 103. These transmissions and receptions are performed via a common channel.

  When the paging signal is received by the radio base station 103, the base station apparatus control unit of the radio base station 103 starts the process of FIG. 5 (step 501). Then, the information on the wired transmission path is stealed, and the calling telephone number included in the calling signal is compared with the telephone number of the local station registered in the USIM card attached to the own apparatus (step 502). ), When this is a “mismatch”, this is notified to the channel resource management unit 1531A, whereby the call signal is transmitted from the radio unit 151 to the service area, and the processing is passed to normal call control, line connection, etc. (Step 503).

  When the comparison result is “match” in step 502, this is notified to the channel resource management unit 1531A. In this case, the telephone numbers compared here are both “090-1234-5673” and “match”. At this time, the channel resource management unit 1531A that has been notified does not perform call connection processing to a normal mobile phone terminal, and does not wastefully use radio resources. Then, the local station transmits a connection request to the upper radio network control apparatus via the uplink common channel, thereby forming a communication path with the mobile phone terminal 1012 that has made a call in the same manner as in a normal case (step 504). ). Of course, this communication channel is a channel using individual channel resources, and the subsequent communication between the radio base station and the mobile phone terminal is performed using this channel.

  When the communication path is formed, the mobile phone terminal 1012 transmits control information for controlling the control target device. In this case, control information instructing to send the image information of the monitor camera 1032 is transmitted to the control device 1031. As this control information, for example, a DTMF (Dial Tone Multi Frequency) signal is used. When the base station apparatus of the radio base station 103 receives this control information (Yes in step 505), the content of the control information is examined to check whether the control target device and the control content are for the device provided in the own station. (Step 506). At this time, information about the device provided in the local station is registered in the USIM card and used.

  If the check information in step 506 is not control information corresponding to the device of the local station, the mobile phone terminal is notified of the mismatch (step 507), and the process moves to step 510 and new information is sent from the mobile phone terminal. Wait for. If it is received here, it is checked whether the information is new control information or an end signal (step 511). If it is new control information, the process returns to step 506. In this way, when the control information of the device provided in the own station, in this case, the monitor camera 1032 is correctly sent (Yes in step 506), the control information is transferred to the control device 1031 and the control device is preloaded. And the captured image of the monitor camera 1032 is captured (step 508).

  When the control device acquires image data and returns it to the control unit of the base station device, the base station device transmits it to the mobile phone terminal 1012 (step 509) and waits for a response from the mobile phone terminal (step 510). If new control information is sent in this way, the corresponding control is performed (steps 506 to 509). If an end signal is sent (Yes in step 511), the wireless network control device is notified of the end, and the cellular phone The communication path with the terminal 1012 is disconnected (step 512).

  Control of the monitor camera 1033, the air conditioner 1042 of the wireless base station 104, the room light 1043, and the like can be performed in the same manner. In addition, these devices can be controlled from a personal computer or a general telephone connected to the public network 5 (FIG. 4). In device control via these control devices 1031 or 1041, a control program for each device may be prepared in the control device. For example, the mobile phone terminal 1021 located in the service area of the radio base station 102, In order to be able to control the monitor camera of the radio base station 101 that does not have a control device as an external device from any mobile phone terminal within the service area of the radio base station 101, the control program is stored in the base station device. It shall be prepared in the control part.

  As described above, the monitor camera and various devices provided at the installation location of the wireless base station can be operated from the mobile phone terminal by allowing the base station apparatus itself to be connected to the network as a terminal apparatus. Thus, by providing a new service to the owner of the wireless base station installation location, it becomes easy to secure the installation location of the wireless base station. This is very effective when more radio base stations need to be installed in order to realize future high-quality communication.

  Also, if the USIM card is opened to individuals, it can be a new source of fee income. Also, by opening the USIM card to the general public, it becomes possible to provide a new service using a device installed in the radio base station. Furthermore, when a wireless network control device wants to send and receive data between a device at the location of the wireless base station and a public network terminal, a mobile phone terminal has conventionally been prepared there, via a wireless line. Although it is necessary to perform data transmission / reception, if the base station apparatus of the present invention is installed, the data transmission / reception can be performed only by the wired transmission path, and there is an effect that the utilization efficiency of the wireless transmission path can be improved.
