Problems solved by technology
[0014] It can be seen from the above description that the current HSDPA flow control method must include two processes, that is, the process of NodeB responding to RNC with RADIO LINK SETUP RESPONSE / RADIO LINKRECONFIGURATION READY message, and the process of NodeB sending HS-DSCHCAPACITYALLOCATION control frame to RNC. HSDPA The flow control process needs to be further optimized
Moreover, in application scenarios such as sufficient bandwidth of the Iub interface, and scenarios such as requiring fixed bandwidth allocation to users (such as VOIP services), after the RNC performs initial authorization, it must also receive the HS-DSCH CAPACITY ALLOCATION control frame before sending NodeB sends MAC-dPDU, resulting in a long delay in sending MAC-d PDU
In addition, the HS-DSCH CAPACITYALLOCATION control frame of the data layer does not adopt the confirmation mechanism, which affects the reliability of the HSDPA flow control technical solution

Embodiment Construction
[0034] When the base station in the embodiment of the present invention sends the HS-DSCH capacity allocation information to the corresponding base station controller, it carries the HS-DSCH capacity allocation information in the control layer message and sends it to the base station controller. The base station can send HS-DSCH capacity allocation information to the base station controller after the HSDPA channel is successfully established, and the base station can also send HS-DSCH capacity allocation information to the base station controller in other cases. The embodiment of the present invention does not limit the base station to the base station The timing at which the controller sends a control layer message carrying HS-DSCH capacity allocation information. The establishment of the HSDPA channel here can be for the base station to establish an HSDPA channel according to the RADIO LINK SETUP REQUEST message sent by the base station controller, or for the base station to ...

The invention provides a method, a system and a device for controlling high speed downlink packet accessing flow. A base station carries capacity distribution information of high speed downlink shared channel HS-DSCH in control layer information for sending to a base station controller; the base station controller controls high speed downlink packet accessing flow HSDPA according with the HS-DSCHcapacity distribution information after obtaining HS-DSCH capacity distribution information from received a control layer. The control layer information can establish response information for wireless link and complete information for wireless link reconfiguration; and HS-DSCH capacity distribution information carried in wireless link can be established in extended HS-DSCH initial capacity distribution information unit for responding information / wireless link reconfiguration completing information. The execution mode of the invention can increase HSDPA flow control reliability, and optimize technical scheme of HSDPA flow control.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a high-speed downlink packet access flow control method, system, base station and base station controller. Background technique [0002] HSDPA (High Speed Downlink Packet Access) is an important technology in WCDMA (Wideband Code Division Multiple Access) communication system. [0003] At present, the HSDPA flow control method includes the following steps: [0004] Step 1, RNC (the base station controller in the WCDMA system) sends the RADIO LINK SETUPREQUEST / RADIO LINK RECONFIGURATION PREPARE (radio link establishment request / radio link reconfiguration preparation) command to the NodeB (the base station in the WCDMA system) to Instruct NodeB to establish HSDPA channel. [0005] Step 2, NodeB responds to RNC RADIO LINK SETUP RESPONSE / RADIOLINK RECONFIGURATION READY (radio link setup response / radio link reconfiguration complete) message, this message can optional...
