Abstract

PURPOSE:To make the quality of call connecting service uniform by gathering real traffic data on respective radio base stations, and dynamically allocating the number of channels and radio frequencies of the respective radio base stations at specific time intervals according to real traffic which varies daily and hourly. CONSTITUTION:A mobile body terminal 5 is connected to transceivers 1 of plural radio base stations 2, 3, and 4 and connected to a mobile body communication exchange 9 by plural multiplex line interface circuits through controllers 8. The exchange 9 sends the result of the traffic gathering statistical processing of an originating and terminating signal quantity from the terminal 5 to a radio source allocation processor 12 periodically and processes and determine the number of channels and radio frequency data of the transceivers 1 at specific time intervals according to the traffic intensities which vary by the radio base stations 2, 3, and 4. The data are sent to a data down-loading circuit 13, which sends out the number of in operation channels and allocation frequency variation data to the control circuits 8 of the respective base stations.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system using radio, and relates to a radio channel allocation method for a plurality of radio base stations.

[0002]

2. Description of the Related Art A conventional radio channel allocation method collects and analyzes traffic data for each radio base station from a control device or an exchange and analyzes the radio channel allocation for each radio base station as semi-fixed data for the control device or the exchange. This is a method of inputting commands to the data area and allocating based on the data.

[0003]

Since the radio channel allocation in this conventional system is a system in which semi-fixed data is changed by command input, a mobile communication subscriber is required to change a plurality of radios in time like a mobile communication system. Move freely within the service area covered by the base station,
When the traffic corresponding to each wireless base station changes depending on the day of the week, it is difficult to variably specify the number of wireless channels corresponding to each wireless base station and the used wireless frequency.

SUMMARY OF THE INVENTION In the wireless channel dynamic allocation system, the gist of the present invention is a traffic collection statistic processor for collecting real traffic of a plurality of radio base stations and collecting statistics, and this traffic collecting / statistical processor. And a radio resource allocation processing device that determines the required number of radio channels and allocation of radio frequencies to be used on the basis of the output data of the radio channel and the radio channel resource allocation data to each radio base station. A mobile communication system switch including a data downloading circuit; and a radio base station control device for receiving radio channel resource allocation data sent from the data downloading circuit through a data line and controlling the radio device. In a mobile communication system composed of a plurality of radio base stations having radio channels, collecting actual traffic data of each radio base station,
The quality of the call connection service is made uniform by dynamically allocating the number of radio channels and the radio frequency of each radio base station at predetermined time intervals according to the actual traffic that fluctuates depending on the time of day.

[0005]

The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In a mobile communication system composed of a plurality of radio base stations 2, 3 and 4 having a plurality of radio transceivers 1, a mobile terminal 5 preliminarily receives an antenna 6 and an antenna multiplexer 7 of these radio base stations 2, 3 and 4 in advance. The radio base station controller 8 connected to the selected radio transceiver 1
The mobile communication switching system 9 is connected to the mobile communication switching system 9 via a plurality of digital multi-line interface circuits 10. In the mobile communication exchange 9, the traffic collection statistics processing device 11 performs the traffic collection statistics processing of the outgoing / incoming call volume from the mobile terminals 5 corresponding to the respective radio base stations 2, 3 and 4, and the result is a cycle. Wireless resource allocation processing device 1
Sent to 2. In the radio resource allocation processing device 12, the radio base stations 2, 3 and 4 are required to have a predetermined time interval according to the amount of traffic that fluctuates with time for each radio base station 2, 3 and 4. Processes the number of channels of the radio transceiver 1 and the radio frequency data to be assigned. This data is sent to the data downloading circuit 13 at a predetermined time interval. The data downloading circuit 13 sends the number of operating channels of the radio transceiver 1 and the assigned radio frequency change data to each station via the digital multi-line interface circuit 10 to the radio controller 8 of each radio base station 2, 3, 4. To do. By allocating the above dynamic radio channel and radio frequency data, the grade of the call connection service linked to the actual traffic is made uniform.

[0006]

As described above, according to the present invention, the actual traffic for each radio equipment value station is measured and statistics are obtained, and the required number of radio channels and the related radio frequency of each radio base station are periodically determined based on the data. By determining and downloading the necessary data to each radio base station controller, there is an effect that the grade of the call connection service linked to the actual traffic can be made uniform.
