Abstract
This invention relates to methods of initiating a reconfiguration of a cell regarding the number of signalling channels in relation to the number of traffic channels. Each signalling channel (SDCCH/8) contains a number of dedicated control channels (SDCCH). The invention can be divided into two parts, an increase condition in which a traffic channel (TCH) is converted to a signalling channel (SDCCH/8) and a decrease condition in which a signalling channel is reconverted to a traffic channel. These two conditions can be performed independently of each other. In the increase condition, the conversion to a signalling channel is done based on three conditions (1,2,3; FIG. 3) depending on the number of idle dedicated channels (SDCCH) and the number of traffic channels (TCH). In the decrease condition, the conversion (FIG. 4; FIG. 5) is based on the number of signalling channels (SDCCH/8) and the dedicated control channels (SDCCH) in the cell.
