Abstract

The present invention discloses a comprehensive dynamic management scheme of HS-DSCH channel codes, which comprises the steps of: determining a remainder HS-DSCH channel resource of a system when a new HS-DSCH bearer service request is received; calculating a required HS-DSCH channel resource for the new service request; comparing the current system remainder HS-DSCH channel resource with the required HS-DSCH channel resource for the new service request; determining whether there is a need to add new HS-DSCH channel codes based on comparison results, assigning new codes or switching the service request into DCH channel for data transmission in accordance with the actual usage of the current code tree; when the existing HS-DSCH bearer service is completed, calculating a current system HS-DSCH channel resource usage ratio and hysteresis then comparing it with a predefined threshold, and determining whether there is a need to withdraw channel codes based on the results of comparison. The dynamic resource management scheme according to the present invention is well suited for application to future HSDPA technology as the technology is broadly spreading by radio resource management algo…
