DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless paging system.

[0002]

2. Description of the Related Art A conventional radio paging system has a configuration in which only one predetermined frequency (one channel) specific to the system is used as a carrier frequency for a radio channel.

[0003]

The conventional radio paging system described above uses only one predetermined frequency (one channel) specific to the system for the radio channel. If the amount of transmitted information increases excessively, there is a problem in that the information cannot be delivered within a certain time, or a considerable time delay occurs in the information transmission. In particular, when a large amount of information such as alphanumeric (character transmission) or numeric (numeric transmission) is transmitted, this problem becomes conspicuous.

[0004]

According to the present invention, there is provided a radio paging system comprising: a paging main transmitter and a plurality of paging sub-transmitters each transmitting paging information on a channel of a predetermined frequency; The paging command signal is received and the traffic is monitored.If the traffic is less than a preset traffic, only the paging main transmitter is controlled, and the traffic becomes a preset multi-stage traffic. A radio base station having a control unit for controlling the paging main transmitter and the plurality of paging sub-transmitters corresponding to the traffic in each of the stages, and when the traffic is less than a preset traffic, Receiving paging information from the paging main transmitter, When the traffic of the paging has a plurality of preset levels of traffic, the traffic information corresponding to the traffic of each of the stages is received from the paging main transmitter and is classified into a plurality of preset groups for the paging main transmission. And a plurality of paging receivers for receiving paging information from the plurality of paging sub-transmitters.

[0005]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, a paging main transmitter 12 and a paging sub-transmitter 13 for transmitting paging information on channels of predetermined frequencies f ₁ and f ₂ , respectively, and an exchange (not shown) When a plurality of paging command signals are received and the traffic is monitored, and the traffic is less than a preset traffic, only the paging main transmitter 12 is controlled, and when the traffic becomes a traffic of a preset stage. A control unit 1 that controls the paging main transmitter 12 and the paging sub-transmitter 13 according to the traffic at each stage.
1 and paging information from the paging main transmitter 12 when the traffic is less than a preset traffic, and when the traffic becomes a traffic of a preset stage, First, receiving traffic information corresponding to the stage traffic from the paging main transmitter 12 and classifying the traffic information into two predetermined groups and receiving paging information from the paging main transmitter 12 or the paging sub-transmitter 13.
The group of paging receivers 101 to 103 and the second group of paging receivers 111 to 113 are provided.

Next, the operation of this embodiment will be described.

In the radio base station 1, the control unit 11 receives the paging command signal from the exchange and monitors the traffic. If the traffic is less than the preset traffic, it controls only the paging main transmitter 12. by channel f ₁ to transmit the paging information Te. In this case, paging receivers 101 to 103 and paging receivers 111 to 113 are both paging main transmitter 1
By the channel f ₁ by 2 receives the paging information.

When the control unit 11 detects that the traffic exceeds the preset traffic, the control unit 11 causes the paging main transmitter 12 to transmit the traffic information, and the paging sub transmitter 13 also transmits the paging information. Control so that it can be sent.

The paging receivers 101 to 103 and 103 that have received the traffic information and the paging receivers 101 to 103 have the current channel f _1.
, And the paging receiver 111 to 113 are set to be able to receive the channel f ₂ from the paging sub transmitter 13.

As a result, the paging information from the paging main transmitter 12 is received by the paging receivers 101 to 103, and the paging information from the paging sub transmitter 13 is received by the paging receivers 111 to 113.

Incidentally, the paging receiver 1 in the present embodiment.
01-103 and 111-113 employ, for example, a synthesizer system so that they can operate on a plurality of channels.

[0014]

As described above, according to the present invention, a paging main transmitter and a plurality of paging sub transmitters, each of which transmits paging information on a channel of a predetermined frequency, and a plurality of paging commands from a switching center. When the signal is received and the traffic is monitored, and the traffic is less than the preset traffic, only the paging main transmitter is controlled. And a radio base station having a control unit for controlling the paging main transmitter and the plurality of paging sub-transmitters, and receiving paging information from the paging main transmitter when the traffic is less than a preset traffic. And the traffic becomes a multi-stage traffic And paging that receives traffic information corresponding to traffic at each stage from the paging main transmitter and is classified into preset groups and receives paging information from the paging main transmitter or multiple paging sub-transmitters. Providing the receiver makes it possible to efficiently use a plurality of channels and simultaneously transmit paging information when traffic increases almost without delay.

Claims (1)

(57) [Claims] 1. A paging main transmitter and a plurality of paging sub-transmitters each transmitting paging information on a channel of a predetermined frequency, and a plurality of paging command signals from an exchange are received to monitor traffic. If the traffic is less than a predetermined traffic, the paging main transmitter alone is controlled, and if the traffic becomes a predetermined multi-stage traffic, the paging is performed in accordance with the traffic of each of the stages. A radio base station having a main transmitter and a control unit for controlling the plurality of paging sub-transmitters, and when the traffic is less than a preset traffic, receiving paging information from the paging main transmitter; The traffic is divided into a plurality of preset traffic levels. Then, the traffic information corresponding to each of the stages of traffic is received from the paging main transmitter and is classified into a plurality of preset groups, and the paging information is received from the paging main transmitter or the plurality of paging sub transmitters. And a plurality of paging receivers.
