Problems solved by technology

[0006] According to the above characteristics, it can be seen that for IM-type pulse-type traffic services, if frequent migration between FACH state and DCH state will undoubtedly lead to waste of air interface resources
There is currently no effective solution to this problem

Embodiment Construction

[0021] According to the characteristics of the IM-type pulse-type traffic service mentioned above, the embodiment of the present invention provides a traffic-based channel migration method, which enables the I / B type (interactive / background, interactive type) defined by 3GPP Background class) All services (including web browsing, FTP download, IM services, etc.) should be kept on the FACH channel as much as possible, which can avoid the waste of air interface resources caused by the back-and-forth migration of FACH state and DCH state.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0023] According to an embodiment of the present invention, a method for channel migration based on traffic is provided. In this method, the tr...

Abstract

The invention discloses a service volume based channel transfering method, which comprises the following processes: presetting uplink throughput threshold, downlink throughput threshold and service volume measurement mean value threshold; setting uplink condition according to the uplink throughput threshold and the service volume measurement mean value threshold, and setting downlink condition according to the downlink throughput threshold; when a 4A event is reported and meets the uplink condition and the downlink condition, the radio network controller transfers from forward accessing channel state into dedicated channel state. Applying the invention, for the I / B type service with 3GPP definition such as IM type pulse service volume service, can avoid transferring between FACH state andDCH stat, thereby avoids air interface resource waste.

Description

technical field [0001] The present invention relates to a Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, WCDMA for short) system in the communication field, and in particular, to a method for channel migration based on traffic. Background technique [0002] In a WCDMA system, Radio Resource Control (RRC) performs dynamic radio bearer control by configuring Traffic Volume Measurements. like figure 1 As shown in the figure, the main principle of dynamic radio bearer control is: when the measured traffic value (Buffer Occupancy, BO for short) is greater than a certain threshold 4AThreshold, a 4A event (4A Event) is reported, which is used as a trigger for the low-rate radio bearer to transfer to the high-rate radio bearer. The condition of the bearer migration process or as a constraint condition of the migration, when the measured traffic value BO is less than a certain threshold 4B Threshold, a 4B event (4BEvent) is reported as a condition fo...
