Dedicated physical channel allocation method and RNC (radio network controller)

Abstract

The invention provides a dedicated physical channel allocation method and an RNC (radio network controller). The method comprises steps as follows: the RNC recognizes the business type of a terminal; the RNC inquires the optimum matching bandwidth corresponding to the business type in a preset business-bandwidth correspondence table according to the recognized business type; and the RNC allocates a dedicated physical channel to the terminal according to the optimum matching bandwidth. According to the invention, the corresponding bandwidth is obtained based on the recognition result of the business type through table lookup, thereby realizing the allocation of the dedicated physical channel. Compared with the prior art, waiting traffic accumulation and RB (radio bearer) reconfiguration are not required, thereby overcoming the time delay problem.

Description

technical field [0001] The invention relates to a dedicated physical channel allocation method and an RNC, and belongs to the technical field of the third generation mobile communication (abbreviation: 3G). Background technique [0002] Dedicated physical channel allocation technology is a 3G system, including: Time Division Synchronous Code Division Multiple Access (TD-SCDMA for short) system and Wideband Code Division Multiple Access (WCDMA, Abbreviation: WCDMA) technology commonly used in the system. A common practice in the industry is to allocate channel resources according to traffic reports reported by terminals. [0003] Specifically, when the terminal detects that the traffic volume is higher than a certain threshold, it reports a 4A report, and the radio network controller (Radio Network Controller, referred to as: RNC) increases the bandwidth resource of the dedicated physical channel of the terminal according to the 4A report; similarly , when the terminal dete...

AI Technical Summary

Problems solved by technology

The amount of traffic that needs to be accumulated depends on the threshold and the delay of the radio bearer (Radio Bearer, RB) reconfiguration process. The wireless transmission bandwidth can be effectively improved after the RB reconfiguration is completed. At this time, the data transmission to be sent The longer the delay, the higher the Transmission Control Protocol (Transmission Control Protocol, referred to as: TCP) protocol transmission congestion.

[0006] 2. This allocation method is only allocated based on the detection results of the terminal without considering the bandwidth requirements of the service itself, so it is easy to cause a mismatch between the allocated bandwidth and the bandwidth required by the service, resulting in waste of resources and an increase in the number of RB reconfigurations

[0007] 3. Since this allocation method does not consider the bandwidth requirements of the business itself, it is impossible to tilt the resources of key businesses during resource allocation to achieve targeted business guarantees
