Abstract: This invention relates to methods of reconfigurating a cell. 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. The increase condition comprises the step of increasing the basic configuration by configure a traffic channel (TCH) to a dedicated control channel (SDCCH/8) if the channel utilization indicates that the basic configuration would have given a certain congestion level. The decrease condition comprises the step of decreasing the basic configuration by configure a dedicated control channel (SDCCH/8) to a traffic channel (TCH) if the channel utilization indicates that the basic configuration woul d have given a certain congestion level.

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.

Abstract: A method and system for load balancing used in a mobile telecommunications network. The load balancing system includes a mobile services switching center and a first base station controller coupled to the mobile services switching center for managing a first plurality of cells. The load balancing system further includes a second base station controller coupled to the mobile services switching center for managing a second plurality of cells, where one cell of the first plurality of cells is adjacent to one cell of the second plurality of cells. The second base station controller includes a processor responsive to receiving a first load indication message from the first base station controller in order to determine whether to handover at least one ongoing call from the one cell of the second base station controller to the one cell of the first base station controller.

Abstract: Methods of reconfiguring a cell regarding the number of signaling channels in relation to the number of traffic channels. Each signaling channel (SDCCH/8) contains a number of dedicated control channels (SDCCH), wherein a number of dedicated control channels are included in a basic configuration of control channels. If the channel utilization indicates that a basic configuration of control channels is congested for more than a certain percentage of time, a dedicated control channel is added to the basic configuration. If it is determined that the basic configuration, less one control channel, is congested less than a certain percentage of time then a control channel is removed from the basic configuration.
