FIG. 4 is a time chart for explaining an example of the operation of the subscriber wireless access system according to the present embodiment, in which both the external power supply voltage and the built-in battery voltage are required to drive the subscriber unit 6. At time T0, the power supply is switched to the power supply by the built-in battery 16 at time T0.
At 1, the remaining capacity of the built-in battery 16 decreases and the state immediately before the subscriber unit 6 stops due to power cut-off, then the subscriber unit 6 stops due to power cut-off, and the power failure is restored at time T2. An operation example in which power is supplied from the external power supply circuit 15 is shown.

In FIGS. 1-4, the external power supply is cut off at time T0 due to a power failure or the like from a state where both the external power supply voltage and the built-in battery voltage satisfy the voltage values necessary to drive the subscriber unit 6. External power supply voltage is 0 [V]
And the built-in battery voltage satisfies the voltage value required to drive the subscriber device 6, the message generator 12 determines that power is being supplied from the built-in battery 16, A battery power supply signal is sent to the communication processing unit 11.

Upon receiving the internal battery power supply signal, the communication processing section 11 sends the signal to the wireless service control device 4 via the base station 5. In the wireless service control device 4, when the message receiving unit 8 receives the built-in battery power supply signal via the communication processing unit 7, the message receiving unit 8 writes the content into the memory 9.

At time T 1, the internal battery voltage becomes lower than a predetermined value (warning voltage) during operation with the internal battery 16, for example, a voltage value required for operating the subscriber unit 6 (operation required voltage). If it is just before the drop, the message generator 12 sends a built-in battery voltage warning signal to the communication processor 11.

In the wireless service control device 4, when the message receiving unit 8 receives the built-in battery voltage warning signal via the communication processing unit 7, the message receiving unit 8 writes the content into the memory 9. Thereafter, the internal battery voltage reaches the required operation voltage, and the operation of the subscriber device 6 is turned off.

At time T2, when the external power supply is restored and the power supply is switched to the external power supply circuit 15, the message generator 12 informs that the external power supply voltage is higher than the voltage value required to drive the subscriber unit 6. And sends an external power supply signal to the communication processing unit 11. The built-in battery 16 is charged by the restored external power supply voltage. When receiving the external power supply signal, the communication processing unit 11 sends the signal to the wireless service control device 4 via the base station 5.

By confirming the contents on the display 10, it is possible to know whether the current power supply to the subscriber device 6 is performed by the external power supply or the built-in battery 16. Also, when the built-in battery voltage from the built-in battery 16 falls shortly before dropping below the voltage value required to operate the subscriber unit 6,
Since the message generator 12 sends out the internal battery voltage warning signal immediately before the operation of the subscriber device 6 is stopped, even if the subscriber device 6 cannot communicate with the base station 5, It is possible to distinguish whether the cause is a power failure or a failure.
