In S22, the relay station 2 relays the radio wave condition to the server 1. Then, the server 1 receives and stores the radio wave condition from the mobile terminals 3, 4 and the like.

In S23, the server 1 transmits a radio wave condition interval change request to the relay station 2. For example, the relay station 2 may be requested to change from the state in which the radio wave status is collected from the mobile terminals 3 and 4 at intervals of 5 minutes to the state in which the radio wave status is collected from the mobile terminals 3 and 4 at 1 minute intervals.

In S33, the portable terminals 3 and 4 transmit the radio wave condition (radio wave intensity or out of service area, position information, time) to the relay station 2 at regular intervals.

In S34, the relay station 2 relays the radio wave condition to the server 1. As described above, the server 1 arbitrarily changes the transmission interval of the radio wave condition to the mobile terminal as occasion demands, changes in the radio field intensity with the passage of time, and further, at each position when each mobile terminal moves. It is possible to collect the radio field strengths in detail and create a map in which the status of the radio wave strengths is displayed in detail on the map.

FIG. 8 is a flowchart (part 2) for explaining another operation of the present invention. In FIG. 8, in S21, the portable terminals 5 and 6 outside the service area obtain the radio wave condition at regular intervals,
Save until it is within the area. This is because the mobile terminals 5 and 6 are out of range and the radio wave condition cannot be transmitted to the relay station 2. Therefore, the radio wave condition is stored here in association with the time.

In step S22, when the portable terminals 5 and 6 enter the area, the stored radio wave conditions (out-of-range, position / position information,
Time) to the relay station.

In S23, the relay station 2 relays the radio wave condition to the server 1. From the above, when the mobile terminal is out of range,
Save out-of-range, location information, time as radio wave condition,
When the mobile terminal moves into the service area, the stored radio wave status is transmitted to the server 1 via the relay station 2, and the server 1 receives the radio wave status from the mobile terminal out of the service area (out of service area, location information, time).
It is possible to collect and display the symbol of the mobile terminal and the fact that it is out of range on the map.

FIG. 9 is a flowchart (No. 3) for explaining another operation of the present invention. In FIG. 9, in S41, the mobile terminals 3 and 4 acquire the radio wave condition (here, the radio wave intensity or out-of-range, position information, time) at a constant interval and store it.

In S41 ', the mobile terminals 5 and 6 acquire the radio wave condition (here, out-of-range, position information, time) at a constant interval and store it.

In S42, if the radio wave condition can be shared between the mobile terminals 3, 4, 5 and 6, the radio wave condition is shared (the communication of the mobile terminals 3, 4, 5 and 6 described later in FIG. 10). According to the method, directly communicate with each other to share and keep the radio wave condition).

In step S43, the portable terminals 3 and 4 are transmitted to the relay station 2 when the portable terminals 3 and 4 are in the zone of the relay station 2 or have entered the zone. As a result, when any one of the mobile terminals 3 and 4 is within the range of the relay station 2 or when the mobile station enters the range, the mobile terminals which are within the range or within the range are shared and held. , 5 and 6 are collectively (represented) and transmitted to the relay station 2.

In S44, the radio wave condition of any one of the mobile terminals 3 and 4 transmitted to the relay station 2 in S43 among the mobile terminals 3 and 4 is discarded.

In S45, a discard request is transmitted to all the mobile terminals that store the transmitted radio wave condition.

In S46, the transmitted radio wave condition is discarded when a predetermined time has passed or when a discard request is received. As a result, all radio wave conditions transmitted to the relay station 2 are discarded.

Through S41 to S46 described above, the radio wave conditions (radio wave intensity or out-of-range, position information, time) acquired by communicating with each other among the mobile terminals 3, 4, 5, 6 are shared, and When the mobile terminal is in or out of the service area, all the radio wave conditions that are collectively held in the relay station 2 are transmitted and relayed to the server 1, so that the server 1 is in service or out of service. , It is possible to collect the radio wave conditions of all the mobile terminals and create the map such as that shown in FIG.

In S48, the server 1 transmits a radio wave condition interval change request to the relay station 2. For example, the change request from the 5-minute interval to the 1-minute interval is transmitted.

In step S49, the request for changing the radio wave condition interval is transmitted to the mobile terminals 3 and 4 within the range of the relay station 2.

In step S50, when the radio wave conditions can be shared between the mobile terminals 3, 4, 5, and 6, the radio wave condition interval change information is shared (here, 5 to 1 minutes are shared).

In S51, the intervals at which the mobile terminals 3 and 4 acquire and save are changed (for example, changed from 5 minutes to 1 minute).

In S52, the portable terminals 3 and 4 are both out of service here. In S53, since the mobile terminals 5 and 6 have received the interval change in S50, the interval at which the radio wave condition is acquired and stored is changed (here, changed from 5 minutes to 1 minute).

In step S54, if the radio wave condition can be shared between the mobile terminals 3, 4, 5, and 6, the radio wave condition is shared (communicate with each other and hold the radio wave condition).

In S55, the portable terminal 3 is in the range here. In S56, the mobile terminal 3 transmits the radio wave condition to the relay station. Here, all the radio wave conditions of the mobile terminals 3, 4, 5, 6 which are shared by the mobile terminal 3 are transmitted to the relay station 2.

In S57, the radio wave condition transmitted by the mobile terminal 3 is discarded. In S58, a discard request is transmitted to all the mobile terminals (here, the mobile terminals 4, 5 and 6) that store the transmitted radio wave condition.

In S59, the transmitted radio wave condition is discarded when a predetermined time has elapsed or when a discard request is received. As a result, in this case, the mobile terminals 4, 5, and 6 have discarded all radio wave conditions transmitted to the relay station 2 by the mobile terminal 3.

In S60, the relay station 2 receives the radio wave condition transmitted in S56 and relays it to the server 1.

By the above S48 to S60, the server 1
It is possible to change the radio wave condition acquisition interval from, for example, 5 minutes to 1 minute, and collect the radio wave condition from each mobile terminal 3.4.5.6 at a changed interval regardless of whether it is in the service area or out of the service area.

In step S61, the server 1 transmits to the relay station 2 the end of changing the radio wave condition interval. In S62, the end of changing the radio wave condition interval is transmitted to the mobile terminals 3 and 4 within the range of the relay station 2.

In S65, if the radio wave condition can be shared between the mobile terminals 3, 4, 5 and 6, the radio wave condition is shared (the radio wave condition is communicated between the mobile terminals 3, 4, 5 and 6 to each other. Save each other).

In step S66, when the mobile terminals 3 and 4 are within the range of the relay station 2 or when the mobile terminals 3 and 4 enter the range, the data is transmitted to the relay station 2 (all the radio wave conditions of the mobile terminals 3, 4, 5 and 6 are relayed). Send to station 2).

In S67, the relay station 2 relays the radio wave condition to the server 1. By the above S61 to S67, the radio wave condition acquisition interval is returned to the original value (for example, every 5 minutes), and the server 1 can collect the radio wave conditions of all mobile terminals regardless of whether they are in the service area or out of the service area. .
