JPS60162318A - Release system of selective call signal - Google Patents

Abstract

PURPOSE:To attain the smooth communication even in case the reception fails for a selective call signal sent from a base station, by adding a timer to a mobile station to secure the automatic release of said call signal. CONSTITUTION:A timer 8 is provided to a call part 4 to be selected and then started at a time point when another selective call signal (clock signal) is received. Then a signal is delivered to a selection release control part 7 after a fixed period of time. The part 7 controls the part 4 by the signals supplied from the part 4 and the timer 8. Thus a sound output is delivered from a speaker 6 for monitor of other channels. At the same time, a transmission/reception operation is possible. Thus it is possible to attain the smooth communication even in case the reception fails for the selective call signal sent from a base station.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a selective paging signal release method in a wireless communication system.

FIG. 1 is a block diagram showing an example of a selective calling mobile station in a conventionally used wireless communication system.

In the figure, 1 is an antenna, 2 is a transmitter, 3 is a receiver, and 4
5 is a selected discharge section, and 5 is a control operation section.

Next, this operation will be explained.

Radio waves from the base station are received by the receiver 3 through the antenna 1, the selected call ratio multiple is detected by the selected output unit 4, and the control operation unit 5
is controlled, and the demodulated audio output from the receiver is output from the speaker 6. However, in the conventional system, the signal detection at the selective calling unit 4 is controlled only by the paging signal from the base station, so if the selective paging signal cannot be received from the base station while moving, There was an inconvenience that the system became locked and could not receive the 9th selective call signal, making it impossible to make a call.

In order to eliminate these drawbacks, the present invention provides a selective calling section 4.
The purpose is to automatically control the timer and cancel the 9 selective call ratio multiplication even if a selective call signal cannot be received from the base station, thereby ensuring smooth wireless communication. This is what I did.

FIG. 2 is a block diagram showing an embodiment according to the present invention,
The same symbols are used for the same parts as in FIG.

7 is a selection cancellation control unit, and 8 is a timer.

Next, this operation will be explained.

The reception operation of radio waves from the base station received by antenna 1 is °
Since it is the same as the example shown in FIG. 1, a detailed explanation of the selective call cancellation operation according to this embodiment will be explained below.

When a base station selectively calls any mobile station.

A plurality of other mobile stations enter a locked state. Since transmission and reception operations are disabled from the moment this lock signal is received, if the release signal from the 9th base station cannot be received, the locked state continues.

After a certain period of time has elapsed, a signal is output to the 2 selection cancellation control section 7. In the selection cancellation control section 7, the selected calling section 4 and the timer 8
The selected calling unit 4 is controlled by a signal from the station, and audio output is output from the speaker 6, allowing monitoring of other stations and enabling transmission/reception operations.

As explained above, according to the second aspect of the present invention, even if the mobile station is in a state where radio wave propagation is poor, the locked state does not continue for 5 times, and one call is not disabled.

Information transmission between a base station and a mobile station can be performed reliably, and a more excellent wireless communication system can be constructed.
