Embodiment

[0038] Examples, such as Figure 6 As shown, the processing flow after data overload occurs:

[0039] S10. When overload occurs, the RNC data processing unit notifies the MAC-d entity of the overload information.

[0040]After the NodeB sends the traffic allocation message to the RNC, the MAC-d entity in the RNC will receive the NodeB traffic allocation message and send data on the corresponding HS-DSCH according to the traffic allocated in the traffic allocation message, each HS- DSCH has no relation to each other. Because the NodeB often only allocates traffic according to its own air interface capability or state when performing traffic allocation, without considering other factors such as Iub interface transmission resources, it may happen that the RNC is requested to send a large amount of traffic on a certain HS-DSCH at certain moments. data, which may cause the burst traffic overload on the certain HS-DSCH to cause the overload of the RNC data processing unit or the o...

Abstract

The disclosed data transmission method for high-speed down grouping access business comprises: RNC data-process unit notifies the overload information to a MAC-d entity; the latter controls flow rate according to received information. This invention can release overload efficiently, ensures network circulation and system normal running.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a data transmission method for high-speed data packet access services. Background technique [0002] With the rapid development of the third-generation mobile communication technology, the R5 protocol of WCDMA (Wideband Code Division Multiple Access) provides high-speed downlink packet access HSDPA (High Speed ​​Downlink Packet Access) technology. The technology involves the realization of the radio access network (Radio Access Network) side. Using this technology can theoretically increase the downlink data rate of the WCDMA system to about 10Mbps, significantly improve the capacity of the communication system, and transmit media services of digital TV quality. It has great application prospects and is an important technology in the third generation mobile communication technology. Through this technology, users can feel the advantages of the third-generation mobile commun...
