の無線局ゾーン内のトラフィック敏をさげいている。In conventional mobile communications based on the radio station zone system that repeatedly uses radio frequencies, the number of radio frequency channels assigned to each radio station is one, and the amount of traffic expected in each radio station zone is constant. It is determined to satisfy the service standards of Then, according to the determined number of channels, radio frequencies designed to prevent radio frequency interference are fixedly allocated to each radio station zone. In each radio station zone, traffic sensitivity within each radio station zone is reduced within the range of the number of channels based on the assigned radio frequency.

ルを利用出来ないことである。However, in this method where radio frequency channels are fixedly assigned to each radio station zone, no matter how many radio frequencies are used repeatedly, as long as a fixed band of radio frequencies is used, the radio station zone method There will be waste. This waste caused by the conventional method means that channels with the same radio frequency that cannot be allocated for each station are not used even if a situation occurs in which the traffic in other radio station zones increases more than expected. The problem is that it is not possible to use channels based on radio frequencies in radio station zones where there are no radio stations.

Mobile switching center M'l' SO is located in wireless station zone Z! where traffic volume is low! Channels 6 to 10 in the radio station zone Z6 and channels 56 to 6o in the radio station zone Z6 are rotated to the radio station zone ZK. In the wireless station zones zl and Zs, the use of channel numbers transferred to the non-side station zone Z7 is restricted. Furthermore, radio station zone Z7iJ:, among the channels assigned in radio station zone Z1, ask them to turn channels 6 to 10, and if you use this as it is, the channels 1 to 10 used by the neighboring station cl') 88 zone Z8 will be rotated. Of the 10 channels, channels 6, 2, and 10 overlap, causing mutual interference.

特徴とする移動体通信におけるチャンネル方式。Radio frequency interference occurs in a zone-based mobile communication system that utilizes the limited radio frequencies effectively by repeating the same radio frequency communication channel in multiple radio station zones. It has a function to manage the radio frequency channels to prevent the traffic from being disturbed and a function to monitor the traffic volume, and the radio frequency channels pre-assigned to each radio station zone can be allocated to radio stations with less traffic disturbance according to the fluctuations in the traffic volume in the radio station zone. A channel system for mobile communication characterized in that a radio frequency channel assigned to a zone can be used in a radio station zone where traffic volume has increased.
