Abstract

In a mobile cellular radio system, when setting up a new call or when handing over an existing call to a new traffic channel, it is necessary to avoid disturbances on the new traffic channel which can cause poor transmission quality. In order to avoid unnecessary disturbances on the new traffic channel, the signal strength of the mobile station requesting a new channel is measured. In addition, the disturbance levels on the available traffic channels are also measured and then compared with the signal strength of the mobile station requesting a channel. Based on the comparison, a traffic channel is assigned to the mobile station so that the disturbance level on the traffic channel is at least less than or equal to a minimum threshold value. <IMAGE>
