FIG. 4 is an example of a communication sequence in which the wired terminal performs the designated operation when entering the area. First, when the mobile wireless terminal 1 flows into the service area 3 from outside the service area 3, the mobile wireless terminal 1 detects entry into the service area 3 by capturing radio waves or the like (S1), and performs load balancing operation ( S
2), the in-area notification is automatically transmitted to the wired terminal 2 (S3). The wired terminal 2 responds automatically, and the wired terminal 2 detects the inflow of the portable wireless terminal 1 by sending and receiving a message (data) defined as an in-area inflow notification.

The wired terminal 2 which has detected the inflow of the portable wireless terminal 1 into the in-area has designated operation at the time of inflow into the area corresponding to the portable wireless terminal 1 stored in the storage section 25 in advance (for example, when the portable terminal corresponding to the display section 21 is in a portable state). The identification number of the wireless terminal 1 and a display indicating that the wireless terminal 1 has entered the area are displayed) (S4).

FIG. 5 shows an example of a communication sequence in which the portable radio terminal performs the designation operation when entering the area. When the mobile wireless terminal 1 flows into the service area 3 from outside the service area 3, the mobile wireless terminal 1 detects entry into the service area 3 by capturing radio waves or the like (S11), and performs load balancing operation (S12). , The area inflow notification is automatically transmitted to the wired terminal 2 (S13). The wired terminal 2 responds automatically, and by sending and receiving the message (data) defined as the in-area notification,
The wired terminal 2 detects the inflow of the portable wireless terminal 1 into the area.

The wired terminal 2 which has detected the inflow of the mobile wireless terminal 1 searches the designated operation at the time of inflow for the corresponding mobile wireless terminal 1 stored in the storage unit 25 in advance (S1).
4), the designated operation instruction is automatically transmitted to the relevant portable wireless terminal 1 (S15). The mobile wireless terminal 1 automatically responds, and by transmitting and receiving a message (data) in which the operation content is defined in advance, the corresponding mobile wireless terminal 1 receives the specified operation (for example, the display unit 11).
The character information transmitted from the wired terminal 2 is displayed) (S16).

In the processing contents shown in FIG. 5, the communication for the in-area inflow notification and the communication for the designated operation at the time of in-area inflow are separate communications.
It is also possible to carry out the transmission / reception of the telegram of the designated operation at the time of inflow within the area shown in S16 without disconnecting after the communication of the within-area inflow notification shown in S13.

FIG. 6 is a diagram showing an example of a load distribution sequence. In the mobile wireless system, a plurality of mobile wireless terminals 1a to 1n may flow into the service area at the same time. At this time, when the individual mobile wireless terminals 1a to 1n send out the in-area notification without knowing each other's state, the load on the system increases rapidly, the congestion of the exchange / transmission equipment 4 and the wired terminal 2 May cause congestion.

In order to deal with such a situation, as shown in the figure, each of the portable radio terminals 1a, 1b, ..., 1n is different in transmission timing a, b in the load balancing process (S2, S12). , ..., N are transmitted (S3, S13) to distribute the load.

As a concrete load balancing method, inflow is detected in advance for each of the portable radio terminals 1a to 1n (S1, S1).
After 1), a method of explicitly storing different transmission timings in the storage unit 16 and a portable wireless terminal 1a
There is a method in which each mobile wireless terminal 1a to 1n makes a call at random timing by using a random number or the like each time the call is made from the caller.

As a result, as shown in the figure, the plurality of portable wireless terminals 1a, 1b, ..., 1n issue in-range notifications to the wired terminal 2 at different timings, and the load on the system can be reduced. Like

For example, if the inflow notification of the mobile wireless terminals 1a to 1n is detected at random timing for 0 to 100 seconds after the inflow of the mobile wireless terminals 1a to 1n is detected, all the passengers on the bus can operate the mobile wireless terminals. Congestion can be suppressed even if the inflow occurs within the same range while holding it. In this case, there is a possibility that mobile wireless terminals that have flown into the area at a certain time will accidentally send in-range notifications at the same time due to load balancing processing. It is lower than the probability of doing and does not matter.

As described above, according to the embodiment of the present invention, by providing the in-area inflow notifying means for the portable wireless terminal 1, the in-area in advance stored in the wired terminal 2 or the portable wireless terminal 1 is stored. The designated operation at the time can be automatically performed at the same time as the inflow into the area.

Further, by providing a means for distributing the load when a plurality of portable wireless terminals 1 flow in at the same time, it is possible to avoid problems such as congestion due to a temporary increase in system load at the time of notification of inflow into the area.

[0029]

According to the present invention, the portable wireless terminal can detect the inflow in the area and automatically notify the wired terminal, and at the same time as the inflow into the area, the designated operation at the time of the inflow in the area provided by the system can be executed, and the service provided by the system. The effect of being able to start is obtained. Further, even when a plurality of mobile wireless terminals flow into the service area at the same time, the timing of notification is different, so that the load on the system can be dispersed and stable system operation can be performed.
