Abstract

PURPOSE:To enable a large capacity subscriber system by using a radio control channel efficiently without use of a periodic position registration signal. CONSTITUTION:A subscriber A of a mobile body radio terminal equipment 19 uses in advance a key pad 23 to enter operating time band data using a terminal equipment and data for a service area block in use and sends the data to a radio base station A4 by a radio transmitter-receiver 21 and an antenna 20. The information is sent from the radio base station A4 to a mobile object communication controller 12, a central processing unit 13 processes the data, and the operating time zone data of the mobile object radio terminal equipment number and the service area block data are stored in a memory device 14. When a call comes to the mobile object radio terminal equipment 19, a call signal of the mobile object radio terminal equipment 12 is sent to the radio base station A4 from the radio control channel control circuit 16 based on the stored data.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless mobile communication system, and more particularly to a call control system for mobile terminals.

[0002]

2. Description of the Related Art As a call control method for a mobile terminal in a conventional mobile communication system, there is a method called an all-cell page method. A mobile terminal is called using a control channel of a radio base station. There is also a method called a partial page method, in which a calling signal is transmitted only to the service area based on a periodic location registration signal from a mobile terminal.

[0003]

In the conventional mobile terminal calling method described above, in the former all-cell page method, call (page) signals are sent to all incoming calls of all mobile terminals. Since the data is transmitted, there is a problem that the channel usage rate in the downlink direction (direction from the radio base station to the mobile terminal) of the radio control channel is squeezed as the mobile terminal and the call volume increase.

On the other hand, in the latter partial page system, since the location registration signals periodically rise from all mobile terminals in the uplink direction of the radio control channel (direction from the mobile terminals to the radio base station), the radio control channel is also generated. There was a problem of overwhelming the usage rate.

Also, since both of these systems generate a large amount of radio control channel signals, there is a problem in that the load on the processing unit of the mobile communication control unit becomes large and a large-capacity processing unit is required.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a calling system for a mobile terminal, which reduces the usage rate of a radio control channel and reduces the load on a control device. ..

[0007]

In order to achieve the above object, a mobile terminal calling system according to the present invention has a plurality of mobile wireless terminals accommodated in a mobile communication system using radio having a plurality of service areas. In addition, the mobile communication control device is provided with a sending means for sending a service area classification and a usage time zone to be used in advance to the mobile communication control device via a wireless control channel. Registration means for registering the band, confirmation means for confirming whether the present time is the previously registered time zone when an incoming call to the wireless terminal occurs in the mobile communication control device, and when the confirmation means confirms Calling that sends the call signal of the wireless terminal to the wireless control channel only for the service area category registered in advance A configuration equipped with means.

[0008]

According to the mobile terminal calling system having the above configuration, the mobile terminal previously uses the uplink of the radio control channel for the service area classification information and the usage time zone information used by the subscriber for communication. Then, the mobile communication control device registers these pieces of information, and when an incoming call is made to the wireless terminal, the mobile communication control device confirms whether it is a pre-registered time zone and registers it in advance. The call signal of the wireless terminal is sent to the wireless control channel only for the service area in which it is provided.

Confirmation means for confirming whether the current time is the previously registered time zone when an incoming call to the terminal occurs, and calling the wireless terminal only for the previously registered service area classification when the confirmation means confirms And a calling means for sending a signal to the radio control channel via the radio control channel control circuit 16.

The mobile radio terminal 19 comprises an antenna 20, a radio transmitter / receiver 21, a control circuit 22, a keypad 23 and a handset 24.

The control circuit 22 has a function of sending the service area division and the use time zone, which are input from the keypad 23 and used by the mobile radio terminal, to the radio base station through the radio transceiver 21 in advance.

The details of the operation will be described below. Here, FIG. 2 is a subscriber data configuration diagram of the memory device 14 in FIG. The mobile radio terminal 19 is tuned to the radio control channel 7 of the radio base station A4 having the strongest radio wave except during a call. The subscriber A of the mobile radio terminal 19 previously uses the keypad 23 to input the use time zone data 26-a for using the terminal and the service area classification data 27-a for use. The control circuit 22 of the mobile radio terminal 19 transmits these pieces of information to the radio base station A4 in the service area A1 by the radio transceiver 21 and the antenna 20 which are tuned to the radio control channel 7.

The radio base station A4 receives the information on the antenna 9 and the radio control channel 7, and the data line 1

When an incoming call is made to the mobile radio terminal 19 from the public communication terminal 18 connected to the public communication network 17, the program stored in the memory device 14 of the mobile communication control device 12 causes a central operation. The processing device 13 performs call connection control, but checks the use time zone data 26-a and the service area classification data 27-a stored in the memory device 14 corresponding to the mobile radio terminal number 25-a. , The current time is confirmed by the clock circuit 15, and if it is within the use time zone data 26-a, based on the data of the service area classification data 27-a, if the service area A1
In the case of only the division, the free radio voice channel 8 of the radio base station A4 is secured, and the radio control channel control circuit 16 stores the call signal of the mobile radio terminal 12 and the radio voice channel 8 information in the radio control channel 7. Is transmitted via the data line 10. Antenna 9 at radio base station A4
More radio waves are emitted.

In the mobile radio terminal 19, the antenna 20 and the radio transmitter / receiver 21 receive the calling signal and the radio voice channel 8 information, and the radio transmitter / receiver 21 is designated by the control circuit 22 from the radio control channel 7. Switch to audio channel 8. As a result, the handset 24

And the use time zone information are registered in the mobile communication control device by using the uplink of the wireless control channel, so that it is not necessary to send a call signal to all incoming calls in all service areas, and The usage rate of the downlink channel of the control channel can be suppressed.
Further, the periodic position registration signals from all mobile terminals are unnecessary, so that the usage rate of the uplink channel of the radio control channel can be suppressed.

Further, by providing a communication use time zone for each mobile terminal, it is possible to suppress the transmission of unnecessary call signals, which has the effect of reducing the usage rate of the radio control channel. Further, the total signal amount is reduced, which has the effect of reducing the load on the processing device of the mobile communication control device.
