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 algorithms of radio network controller.

摘要:
A self-adaptive jitter buffer adjustment method for packet-switched network is presented in this invention, which involves both positive adjustment to jitter buffer and negative adjustment to jitter buffer. The positive adjustment part performs a positive adjustment to the jitter buffer according to an indication of a sequence number of the packet delaying, to absorb larger network jitters by dynamically detecting sequence numbers of the packets in the jitter buffer. The negative adjustment part performs a negative adjustment to the jitter buffer when the filling level descends, to match smaller network jitters by periodically detecting a filling level of the jitter buffer. This invention realizes the dynamic tracking of network jitter, so that a self-adaptive adjustment to the jitter buffer working parameters can be achieved. Comparing with traditional methods for self-adaptive buffer adjustment, the present method reduces the complicacy and computational costs of the self-adaptive jitter buffer adjustment algorithm. At the same time, the impact of self-adaptive jitter buffer adjustment on the performance of the entire system is greatly reduced.
