The invention relates to a method for dynamically allocating the carrier's resources of GSM base station. 2~N pieces of antennas are used in one or two partitions which need to enhance the flow-volume. Among the antennas in each partition, one keeps covering on this partition, and the others are used for carrier switching of the other partitions. The local business quantity detection units detect the communication quantity of one or two partitions with enhanced flow-volume though the local user quantity detection units. Then the control units control the attenuator to schedule the carrier resources and switch carriers of the other partitions to the carrier that needs communication quantity. During the process, coverage is remained for the other partitions. So the number of the carrier can be adjusted among different partitions of one base. N is less than of equal to 6. During the progress of scheduling and releasing carrier resource, the attenuator partly reduces the signals to make the user of this carrier resource switch to the others and not disconnect. |
