Problems solved by technology

[0014] This method avoids the ping-pong adjustment phenomenon of SRNC to the data delivery time. However, when the time delay of the two branches is greatly different, the data transmission between SRNC and base station is as follows: Figure 4 As shown, the data of the branch with a small delay falls before the time window of the base station, and the branch will continuously report the time adjustment control frame, requiring the SRNC to delay the data delivery time. This frequently transmitted time adjustment control frame takes up The transmission bandwidth between the base station and SRNC, thus affecting normal data transmission and wasting network resources

Embodiment Construction

[0044]If the SRNC only adjusts the data sending time according to the reference link, and the data sent to the base station according to the adjusted data sending time can fall within each time window as much as possible, then the ping-pong adjustment of the data sending time by the SRNC can be effectively avoided And when the wireless link transmission delay difference is large, the base station frequently reports the time adjustment control frame, which affects the normal data transmission.

[0045] Therefore, the core of the present invention is: obtain the data transmission time delay of each wireless link of the interface between SRNC and the base station, adjust the corresponding time window parameters of each wireless link according to the data transmission time delay of each wireless link, according to the described each The data transmission delay of the wireless link determines the reference link, and the SRNC adjusts the data sending time according to the time adjust...

Abstract

This invention provides a method for adjusting data downward send time of SRNC including: obtaining data transmission time delays of the radio links of the interfaces between SRNC and the base station, adjusting the time window parameters corresponding to the radio links based on the data transmission time delays, determining a primary link based on the time delay, the SRNC adjusts its data downward send time based on the time adjustment control frame reported by the primary link.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for SRNC to adjust the time for sending data. Background technique [0002] In the wireless communication system, the base station maintains a data receiving window, which is usually called the time window. The schematic diagram of the base station receiving data sent by the RNC (Radio Network Controller) through the time window is shown in the attached figure 1 shown. [0003] figure 1 Among them, the data sent by RNC should fall within the time window of the base station. When the data sent by RNC falls outside the time window, the base station will pass the FP (frame protocol) definition of the IUB (a standard interface) interface. In the in-band signaling process, a time adjustment control frame is sent to the RNC, and the time adjustment control frame contains the difference TOA between the time when the data actually arrives at the base station and...
