  Hereinafter, the wireless relay device of this embodiment will be described in more detail. As shown in FIGS. 1 and 2, the wireless relay device 1 includes a main body housing 10 made of plastic or the like, and an antenna 11 provided on a side surface of the main body housing 10 and covered with plastic or the like. The antenna 11 includes a base station BS antenna 11a for wireless communication with the base station BS and a mobile station PS antenna 11b for wireless communication with the mobile station PS. In addition, a liquid crystal display unit 61 that displays the registered number of mobile stations PS registered in the wireless relay device 1 is provided on a side surface of the main body housing 10.

  The radio relay apparatus 1 shown in the present embodiment is a radio communication system such as PHS that relays radio communication between a mobile station PS and a base station BS in a 4-channel multiplexed TDMA-TDD radio communication system. It is used to relay wireless communication that performs packet switching and circuit switching between the mobile station PS and the base station BS, and supports communication at maximum of 128 kbps.

  As shown in FIG. 2, the radio relay apparatus 1 includes a base station antenna 11a, a mobile station antenna 11b, a control unit 2, a power source 3, a base station side radio communication unit 5a, and a mobile station side radio communication. The unit 5b and the liquid crystal display means 6 are provided.

  The power source 3 is supplied with power from a commercial power source and generates an operating power source for the internal circuit.

  The memory unit 4 can store various data.

  The base station side radio communication unit 5a performs radio communication with the base station BS via the base station antenna 11a, and the mobile station side radio communication unit 5b moves via the mobile station antenna 11b. Wireless communication is performed with the station PS. When relaying communication from the base station BS to the mobile station PS, the base station BS radio communication unit 5a converts the frequency of the signal from the base station BS received via the base station antenna 11a. In the control unit 2, the received information is demodulated and decoded, the received information is analyzed, then encoded and modulated, the frequency is converted by the mobile station side wireless communication unit 5 b, and externally transmitted via the mobile station antenna 11 b. Transmit to mobile station PS. On the other hand, when relaying a signal from the mobile station PS to the base station BS, the signal is relayed through a signal path opposite to that described above, and the signal is transmitted to the base station BS via the base station antenna 11a.

  The control unit 2 includes an identification number receiving unit 21, a storage unit 22, a received electric field strength measuring unit 23, and a received electric field strength threshold setting unit 24.

  The identification number receiving means 21 receives each mobile station PS from data transmitted when a call such as packet switching or circuit switching is made from the mobile station PS by the mobile station antenna 11b and the mobile station side wireless communication unit 5b. The unique identification number is extracted.

  The storage means 22 acquires the identification number of the mobile station PS from the identification number receiving means 21. By storing the acquired identification number in the memory unit 4, the corresponding mobile station PS is registered as a relay target. The storage means 22 performs an operation for storing the identification number in the memory unit 4 only for a predetermined time preset in the memory unit 4 after the operation power is turned on by the power source 3. Further, the storage means 22 performs an operation for storing the identification number in the memory unit 4 up to the maximum number of mobile stations PS that can be registered in the memory unit 4 in advance.

  The received electric field strength measuring means 23 measures the received electric field strength measurement value of the data received from the mobile station PS by the mobile station antenna 11b and the mobile station side wireless communication unit 5b. This received electric field strength measurement value is transmitted to the storage means 22 and compared with a threshold value preset in the memory unit 4. When the received electric field strength measurement value is larger than the threshold value, the storage unit 22 stores the identification number of the corresponding mobile station PS in the memory unit 4.

  The received electric field strength threshold setting means 24 changes and sets the received electric field strength threshold preset in the memory unit 4. The received electric field strength measurement value measured by the received electric field strength measuring means 23 is transmitted by the received electric field strength threshold value setting means 24 by wirelessly transmitting data from the mobile station PS ′ of the other house not to be relayed to the wireless relay device 1. The threshold value is stored in the memory unit 4.

  As shown in FIG. 3, the wireless relay device 1 and the mobile station PS to be registered are in the house A, and the adjacent houses B and C have mobile stations PS ′ and PS ′ ′ that should not be registered. There is. Since the distance to the radio relay apparatus 1 is farther from the mobile station PS 'than the mobile station PS, the received electric field strength of the mobile station PS' received by the radio relay apparatus 1 is smaller than that of the mobile station PS. Furthermore, the received electric field strength of the mobile station PS ′ ′ is even smaller. Therefore, by measuring the received field strength of the mobile station PS ′ closest to the radio relay apparatus 1 that should not be registered, and setting this received field strength measurement value as a threshold value, the mobile station PS that should not be registered. Registration can be prevented by accurately selecting “and PS”.

  Further, the contents of the registration operation of the mobile station PS can be confirmed by the liquid crystal display means 6. As shown in FIG. 1, a liquid crystal display unit 61 composed of a liquid crystal panel is provided on the side surface of the main body housing 10 of the wireless relay device A. When the power supply 3 generates operating power for the internal circuit, the liquid crystal display unit 61 is lit to indicate that the power is turned on. And the memory | storage means 22 will be in the mobile station identification number storage mode which starts time-measurement and receives registration of mobile station PS. During this mobile station identification number storage mode, the liquid crystal display means 6 acquires the number information of the mobile stations PS that can be registered from the control unit 2 and displays the number of mobile stations PS that can be registered on the liquid crystal display unit 61. For example, the number of mobile stations PS that can be registered can be displayed by numbers or symbols. Further, the liquid crystal display unit 61 can display that the mobile station identification number storage mode is within a predetermined time.

  The liquid crystal display means 6 displays the identification number stored in the memory unit 4 on the liquid crystal display unit 61. As a result, it is possible to confirm the storage of the identification number of the mobile station PS to be registered and to know that the mobile stations PS ′ and PS ′ ′ that are not relayed are registered in error. Only the necessary mobile station PS can be registered.

  An operation of registering the mobile station PS in the wireless relay device 1 will be described with reference to FIG.

  When the operation power supply for the internal circuit is generated by the power supply 3 (S1), the storage means 22 starts measuring time (S2). The time measured in the storage means 22 is compared with a predetermined time set in advance in the memory unit 4, and it is determined whether or not the time measured exceeds the predetermined time (S3). If the measured time does not exceed the predetermined time, the storage unit 22 can further register the number of identification numbers stored in the memory unit 4 and the mobile station PS set in the memory unit 4 in advance. The maximum number is compared, and it is determined whether or not the number of identification numbers has reached the maximum number (S4). When the number of identification numbers does not reach the maximum number, the received field strength measurement value is compared with the threshold value preset in the memory unit 4 or the threshold value changed and set by the received field strength threshold value setting means 24. (S5) If the received field strength measurement value is large, it is determined that the mobile station PS is to be registered. If it is determined that the mobile station PS is to be registered, it is next determined whether or not the identification number is already stored in the memory unit 4 (S6). If the identification number is already stored, the identification number is deleted (S7). If the identification number is not already stored, the identification number of the mobile station PS received by the storage means 22 is stored in the memory. Store in the unit 4 (S8). That is, the storage means 22 should register until the set maximum number is reached when the information transmitted by calling the mobile station PS within a predetermined time is acquired via the identification number receiving means 21. It is determined whether the mobile station is a mobile station, and an operation for registering the mobile station PS is performed. Furthermore, registration can be canceled by transmitting data to the radio relay apparatus 1 from the same mobile station PS within a predetermined time.

  Further, the contents of the registration operation of the mobile station PS can be confirmed by the liquid crystal display means 6. As shown in FIGS. 1 and 2, the liquid crystal display means 6 includes a liquid crystal display unit 61 and a liquid crystal display control unit 62.

  When the operation power source of the internal circuit is generated by the power source 3, the liquid crystal display unit 61 is turned on and it can be confirmed that the power source is turned on. And the memory | storage means 22 will be in the mobile station identification number storage mode which starts time-measurement and receives registration of mobile station PS. As shown in FIG. 5, when the mobile station identification number storage mode is within a predetermined time, the mobile station identification number storage mode icon 61a of the liquid crystal display unit 61 is displayed.

  When the storage unit 22 stores the identification number of the mobile station PS in the memory unit 4, the mobile station character 61 b is displayed on the liquid crystal display unit 61, thereby confirming that the mobile station PS is stored in the memory unit 4. It can be easily confirmed. The liquid crystal display unit 61 shown in FIG. 5 shows a case where the number of registerable units is four. When two units are registered, two mobile station characters 61b are displayed with solid lines, and the remaining two units are displayed. By displaying the mobile station character 61b with a broken line, the remaining number of registrations can be displayed. As a result, the number of already registered units can be grasped at a glance, and the remaining number of registered units can be grasped at a glance.

  Further, each mobile station character 61b can be displayed together with the identification number of the mobile station PS, and it can be easily confirmed which mobile station PS is registered.

  In this embodiment, the appearance of the mobile terminal is displayed on the liquid crystal and the registration status such as the number of registered mobile stations PS is displayed. However, the present invention is not limited to this. For example, instead of the appearance of the mobile terminal, The registration status such as the number of registered mobile stations PS may be displayed by changing the appearance of a character such as an animal on the liquid crystal or changing the expression.

  Further, the radio relay operation mode performs a relay process such as a call or communication performed between the mobile station PS and the mobile station BS, and is the same as a generally known relay process. Is omitted.

  Therefore, in the present embodiment, the identification number receiving means 21, the storage means 22, and the received electric field strength measuring means 23 are provided, and the storage means 22 has the mobile station PS whose received electric field strength measured value is larger than a predetermined threshold value. Since only the identification number is stored, the mobile stations PS ′ and PS ′ ′ of other houses that are not the relay target whose reception field strength is smaller than the mobile station PS existing in the home that is the relay target are stored. It is possible to select and store only the mobile stations PS existing in the house to be relayed. Further, the storage means 22 stores the identification numbers only within a predetermined time, and since the maximum number of identification numbers that can be stored is set, the identification numbers of the mobile stations PS ′ and PS ′ ′ that are not relay targets are set. The possibility of receiving and storing can be reduced. This makes it easy to store only the mobile stations PS existing in the house to be relayed. Further, since the liquid crystal display means 6 displays the number of mobile stations PS in which the identification number is stored in a liquid crystal display, the user can easily confirm the registered number of mobile stations PS on the liquid crystal display unit 61 and register it. Registration work is possible while checking the number. This makes it easy to store only the mobile stations PS existing in the house to be relayed.

  Further, since the liquid crystal display means 6 displays whether or not it is within the predetermined time when the identification number is stored by the storage means 22, whether or not it is within the predetermined time when the mobile station PS can be registered. Can be easily grasped.

  Further, since the liquid crystal display means 6 displays the identification number stored in the storage means 22 on the liquid crystal display section 61, the registered mobile station PS can be confirmed.

  And since it has the received electric field strength threshold value setting means 24 for setting the received electric field strength measurement value of the radio wave received from the mobile station PS as the predetermined threshold value, there is another adjacent house that may be erroneously registered. The received electric field intensity from the mobile station PS ′ existing indoors can be set as a predetermined threshold value. This makes it possible to easily set a predetermined threshold value for accurately selecting a mobile station PS ′ that is not a registration target.

  The storage means 22 deletes the stored identification number when the identification number of the mobile station PS that has already stored the identification number is received within a predetermined time in which the identification number is stored. Therefore, the registered mobile stations PS can be easily deleted individually.

  Next, a radio relay apparatus according to the second embodiment of the present invention will be described. Here, only matters different from those in the first embodiment will be described, and other matters (configuration, operational effects, and the like) are the same as those in the first embodiment, and thus description thereof will be omitted.

  The storage means 22 extends the predetermined time for storing the identification number when one identification number is stored. Hereinafter, an operation of registering the mobile station PS in the wireless relay device 1 will be described with reference to FIG.

  When the operation power supply for the internal circuit is generated by the power supply 3 (S11), the storage means 22 starts measuring time (S12). The time measured in the storage means 22 is compared with a predetermined time set in the memory unit 4 in advance, and it is determined whether or not the time measured exceeds the predetermined time (S13). If the measured time does not exceed the predetermined time, the storage unit 22 can further register the number of identification numbers stored in the memory unit 4 and the mobile station PS set in the memory unit 4 in advance. The maximum number is compared, and it is determined whether or not the number of identification numbers has reached the maximum number (S14). When the number of identification numbers does not reach the maximum number, the received field strength measurement value is compared with the threshold value preset in the memory unit 4 or the threshold value changed and set by the received field strength threshold value setting means 24. If the received field strength measurement value is large (S15), it is determined that the mobile station PS is to be registered. If it is determined that the mobile station PS is to be registered, it is next determined whether or not the identification number is already stored in the memory unit 4 (S16). If the identification number is already stored, the identification number is deleted (S17). If the identification number is not already stored, the identification number of the mobile station PS received by the storage means 22 is stored in the memory. Store in the unit 4 (S18).

  The storage means 22 resets the time measurement (S19) after completing the step of registering (S18) or deleting (S17) the identification number. That is, the storage means 22 resets the time every time the identification number of the mobile station PS is stored or deleted in the memory unit 4. This makes it possible to clearly grasp the predetermined time during which one mobile station PS can be registered.

  Accordingly, the storage means 22 extends the predetermined time in which the identification number is stored when one identification number is stored. Therefore, every time the mobile station PS is registered, the storage unit 22 registers a new mobile station PS. Since a predetermined time for doing so is newly secured, it is possible to secure a grace period for the registration work.
