Example 1

If the caller radio terminal 1a, the receiver radio terminal 1b, and the base station 2 are in an initial state in which call connection is not established, and there is a call request S100 from the caller radio terminal 1a, the base station 2 Confirms the location information of the receiver wireless terminal 1b.

After confirming the location information, the base station 2 requests the paging of the receiver radio terminal 1b (S101).

Subsequently, the base station transmits measurement data of the received electric field strength of the receiver radio terminal and the transmitter radio terminal to the receiver 5 of the transmitter radio terminal 1a and the receiver radio terminal 1b (S102).

The received electric field strength of the radio terminal transmitted to the receiver 5 of the sender radio terminal 1a and the receiver radio terminal 1b, respectively, is transmitted to the receive field strength meter 11 and graphed by decimal or step. The data is quantified, and the quantified data is displayed on each wireless terminal display unit 8.

While the received electric field strength of the wireless terminal metered as described above is displayed, a paging response (S103) is made between the base station 2 and the receiver radio terminal 1b irrespective of the display of the electric field strength, and the paging response is made. When this is done, the base station 2 transmits the incoming information to the caller radio terminal 1a (S104).

When the incoming information is transmitted to the caller radio terminal, the base station allocates a channel between the caller radio terminal and the receiver radio terminal, and switches to the call state mode.

Of course, even in the call state, the base station 2 continuously transmits the received field strength data of the receiver and the sender's radio terminal to the receiver field strength meter 11 of the sender radio terminal 1a and the receiver radio terminal 1b. And display on the display unit 8 of the wireless terminal, so that the reception field for the position of the caller's wireless terminal for the T time period after the call is made after the base station 2 confirms the position of the receiver wireless terminal is established. The intensity information can be provided in real time.

Next, a method for displaying received field strength in a structure in which the receiving field strength meter is configured in the base station will be described with reference to FIG. 4.

Example 2

If the caller radio terminal 1a, the receiver radio terminal 1b, and the base station 2 are in an initial state where call connection is not established, and there is a call request S200 from the caller radio terminal 1a, the base station 2 Confirms the location information of the receiver wireless terminal 1b.

After confirming the location information, the base station 2 requests the paging of the receiver radio terminal 1b (S201).

  Subsequently, the base station measures the data of the received electric field strength of the receiver radio terminal and the sender radio terminal, and quantifies the measured data graphed by decimal or step using a receiving field strength meter (not shown) configured in the base station.

The metered data is displayed on the display unit 8 of the sender radio terminal 1a and the receiver radio terminal 1b (S202).

While the received electric field strength of the wireless terminal metered as described above is displayed, a paging response (S203) is made between the base station 2 and the receiver radio terminal 1b irrespective of the display of the electric field strength, and the paging response is made. If this is done, the base station 2 transmits the incoming information to the caller radio terminal 1a (S204).

When the incoming information is transmitted to the caller radio terminal, the base station allocates a channel between the caller radio terminal and the receiver radio terminal, and switches to the call state mode.

Of course, even in the call state, the base station 2 continuously transmits the received field strength data of the receiver and the sender's wireless terminal to the display unit 8 of the sender wireless terminal 1a and the receiver wireless terminal 1b. From the moment of confirming the position of the wireless terminal to the end of the call after the call connection is made can be provided in real time the location information of the wireless terminal of the caller.

The present invention quantifies the received electric field strength for the position of the wireless terminal of the caller during the T time when the call is made from the call request moment as described above to continuously alarm through the display of the wireless terminal, attempting to call In the process, it is possible to know in advance whether or not the call connection will be made normally.

In addition, when a call drop occurs during a call, the cause thereof can be easily known, thereby improving the service quality of the wireless terminal user.

In addition, the present invention has been described taking a structure in which the received electric field strength for the caller's terminal is quantified in decimal or graph as an example. However, the present invention may be configured by quantifying the sound through a speaker of the terminal or a text message.

The present invention provides a step of making a call connection between the receiver radio terminal 1b and the sender radio terminal 1a via the base station 2, at a position of the radio terminal where the call connection is made before and after the call connection. Measuring each received electric field strength and transmitting the received electric field strength to a receiver of the other party's wireless terminal; quantifying the received electric field strength transmitted to the receiving unit through a receiving electric field strength meter configured in each wireless terminal; By configuring the wireless terminal call system to go through the step of displaying the change in the electric field strength in real time on the display of each wireless terminal,

It is effective for the caller to know the information about the call connection state from the moment of the call request until the call is terminated.

In addition, by providing the information on the received field strength, when the call drop (call drop) occurs during the call can be easily understood the cause can be further improved the quality of service for the user of the wireless terminal.
