Abstract

The invention discloses a method for obtaining Iub interface transmission bandwidth information by a DSP algorithm unit. The method includes the following steps: the transmission unit of the base station detects and obtains the Iub interface transmission bandwidth information, and transmits the Iub interface transmission bandwidth through an Iub interface transmission bandwidth allocation request message. The information is sent to the DSP algorithm unit. Can find out from above-mentioned scheme, because the present invention provides to DSP algorithm unit configuration Iub interface transmission bandwidth information, DSP algorithm unit can calculate each parameter of HS-DSCH capacity distribution according to Iub interface transmission bandwidth information, thereby realizes in HSDPA mode Next, control the Iub interface traffic. The invention makes up for the deficiency of the existing protocol and keeps compatibility with the existing technology. The invention can timely and quickly provide the Iub interface transmission bandwidth information to the DSP algorithm unit, so as to control and adjust the flow of the Iub interface in time.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for obtaining Iub interface transmission bandwidth information by a digital signal processing (DSP) algorithm unit in a High Speed ​​Downlink Packet Access (HSDPA) service mode. Background technique [0002] With the increasing development of mobile communication technology, HSDPA was introduced in the third generation partnership project (3GPP) protocol evolution plan from the third generation version to the fifth generation version. As a very cutting-edge new technology, HSDPA has attracted Great attention and enthusiasm from the industry. Once HSDPA is adopted, in theory, the downlink data rate of the Wideband Code Division Multiple Access (WCDMA) system can be increased to about 10 megabits per second (Mbps), which significantly improves the capacity of the communication system, so that the media of digital TV quality can be transmitted. Business, so HS...
