A telecommunications system and method is disclosed for providing adaptive thresholds for cell load sharing (CLS) based upon the current traffic situations. This can be accomplished by a Base Station Controller (BSC) monitoring the traffic load in a cell during a predetermined time period. If the traffic load is high for the entire time period, the CLS thresholds can be changed to maximize efficient channel resource utilization. In one embodiment, a look-up table can be used to set the thresholds for each cell based upon the traffic level, e.g., the percentage of idle channels, during the time period. Alternatively, the BSC can monitor only the traffic load in a cell with an usually high amount of traffic for the same time period. Thereafter, the BSC can change the thresholds in the high traffic cell and neighboring cells to maximize channel efficiency within the network. |

DETAILED DESCRIPTION The present invention is directed to telecommunications systems and methods for providing adaptive thresholds for cell load sharing (CLS) based upon the current traffic situations.
This can be accomplished by the BSC monitoring the traffic load in a cell during a predetermined time period, e.
g.
, 30 minutes.
If the traffic load is high for the entire time period, the CLS thresholds can be changed to maximize efficient channel resource utilization.
In one embodiment, a look-up table can be used to set the thresholds for each cell based upon the traffic level, e.
g.
, the percentage of idle channels, during the time period.
Alternatively, the traffic load in both the serving cell and neighboring cells (preferably neighbors that are frequent handover candidates, e.
g.
, three neighboring cells) can be monitored for the same time period.
If the BSC determines that the traffic load is higher than usual in the serving cell, the CLS thresholds can be changed in the serving cell as follows: a) increase the threshold for accepting load; and b) decrease the threshold for sharing load.
At the same time, if the traffic load in one of the neighboring cells is normal or lower than usual, the CLS threshold for that neighboring cell can also be changed as follows: a) decrease the threshold for accepting load; and b) increase the threshold for sharing load.
