Later, the signal is transmitted from the indoor antenna 2 to the closed space wirelessly via the duplexer 5. In addition, a signal (uplink signal) wirelessly transmitted from the mobile station apparatus existing in the closed space is received by the indoor antenna 2, separated by the transmitter / receiver demultiplexer 5, and supplied to the amplifier 7 via the directional coupler 6.

In this example, when an identification signal of the indoor mobile station apparatus is included in a radio signal directed from the indoor mobile station apparatus to the outdoor base station apparatus, the identification signal is extracted from the radio signal. As another configuration example, when the identification signal of the indoor mobile station device is included in the radio signal from the outdoor base station device to the indoor mobile station device, the identification signal is extracted from the radio signal. It is also possible to use a configuration to extract.

The communication system of the radio signal used by booster apparatus A1 of this example is shown.

In this case, in this example, signals P1 to P3 for each slot as shown in FIG. 2 are transmitted by radio from each mobile station apparatus MS1 to MS3 by the TDMA method.
In the booster apparatus A1, the indoor antenna 2 receives uplink signals from the mobile station apparatuses MS1 to MS3 in the closed space R1. The received radio signal is frequency-separated by the transmitter / receiver demultiplexer 5, demultiplexed by the directional coupler 6, and input to the decoder 8. The decoder 8 converts the input radio frequency band signal into a baseband signal and outputs it to the circuit of the detector 9. The detector 9 first searches for the synchronization signal from the input baseband signal, and if it finds the synchronization signal in the baseband signal, the detector 9 identifies the mobile station apparatus located at a predetermined time away from the synchronization signal. Extract the signal. The extracted identification signal of the mobile station apparatus is transmitted to the external apparatus A2 via the input / output apparatus 10.

(2) It is assumed that the mobile station device MS2 moves from the inside to the outside of the closed space R1 from the above state and changes to a state in which the two mobile station devices MS1 and MS3 exist in the closed space R1.
In this case, in this example, the booster device A1 does not receive the uplink signal from the mobile station device MS2, and therefore does not receive the identification signal of the mobile station device MS2. Therefore, the identification signal of the mobile station device MS2 is transmitted to the external device. No transmission to A2.
In the external device A2, for example, at a regular timing, the time when the mobile station device identification signal recorded in the MS status list was last received is read from the MS status list, and for a certain time such as 10 minutes, When the mobile station apparatus identification signal (in this example, the identification signal of the mobile station apparatus MS2) is not transmitted from the booster apparatus A1, the corresponding mobile station apparatus (in this example, the mobile station apparatus MS2) is closed space. It is determined that the mobile station apparatus has moved out of R1, and information (mobile station apparatus identification signal information and reception time information) related to the mobile station apparatus is deleted from the MS state list.
Here, FIG. 5 shows an example of recorded contents of the MS state list. In this example, for each of the two mobile station apparatuses MS1 and MS3 remaining in the closed space R1, the mobile station apparatus identification signal and its reception time are recorded in association with each other.
