Dynamic channel configuration method based on source rate estimation

Abstract

There has the features of burst in grouping service and large range of dynamic change in speed rate among the CDMA cellular mobile communication system. If you want to raise the utilization efficiency of the system resources, the reasonable and dynamic channel disposal should be carried out, otherwise the utilization efficiency and the communication quality will be low. The dynamic channel disposal can be realized by measuring service volume and to report the measured service volume. The present patent has provided a dynamic channel disposal method base on the estimation to the service source speed, which can estimate the instant speed of service source quickly and accurately and to dispose the new channel resources according to it for effectively raising the utilization rate of system resources and reducing the unnecessary frequency of channel redisposing.

Description

technical field [0001] The invention relates to a communication system, especially a method for dynamic channel reconfiguration based on source rate estimation in a CDMA cellular mobile communication system. Background technique [0002] With the development and rapid popularization of the Internet, more and more wireless devices (such as mobile phones) provide Internet access functions, and enjoy the packet services with very large data rates of business sources such as WWW browsing, FTP downloading, and E_Mail provided by the Internet. For example, when the user clicks on the WWW page connection, a download request will be sent. During this request, one or more packet sequences will be sent. At this time, there will be a large amount of data on the channel to request rapid transmission; After the document is downloaded, the user spends a certain amount of time reading it, so the amount of data on the channel becomes very small at this time. It can...

Similarly, after receiving a traffic report that the traffic volume is lower than the lower threshold, if the reconfigured capacity is inconsistent with the actual required capacity, it will result in an additional traffic report for reconfiguring the channel capacity

On the one hand, this cannot well meet the business needs of users. On the other hand, it also brings more and unnecessary signaling processes such as traffic reporting and channel reconfiguration, which reduces the overall performance of the system.
