Embodiment Construction

[0072] The core of the present invention is that the mobile terminal and the base station system limit the waiting time when the RLP (radio link protocol) layer (terminal side or base station side) receives network layer data packets in the data transmission process, and collect the data packets collected within a predetermined time. The complete data packet is uploaded to the network layer of the receiving end. If the data frame of the complete data packet is not received within the predetermined time, the data packet will be discarded to avoid excessive time delay due to data frame loss; at the same time, according to the arrival of the data frame The time jitter situation dynamically adjusts the RLP receiving buffer to ensure the voice quality of the VoIP service.

[0073] Those skilled in the art know that WCDMA (Wideband Code Division Multiple Access) / CDMA2000 is a third-generation mobile communication system, which adopts a structure similar to that of the second-generati...

Abstract

The invention discloses a method for reducing the time delay and the time delay vibration of real-time service, which is characterized in that: said method comprises: setting the size of initial receiving buffer area; setting the data frame waiting time according to the sizes of initial receiving buffer area and the application service bandwidth; the sending end divides the network data package of real-time service into several wireless chain protocol data frames to be transmitted to the receiving end; the receiving end receives the wireless chain protocol data frames in the waiting time of data frame; regulating the size of buffer area according to the time delay vibration condition that the wireless chain protocol data frames reach the receiving end. The invention can reduce the time delay vibration caused by the chain circuit transmission, reduce the voice vibration of VoIP service and improve the voice quality of VoIP service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for reducing real-time service delay and delay jitter. Background technique [0002] CDMA (Code Division Multiple Access) mobile communication network is playing an increasingly important role in the mobile communication system because of its large unit capacity, high communication quality and ease of upgrading to the third generation mobile communication system. The current CDMA system, like the GSM (Global System for Mobile Communications) system, basically focuses on processing voice services, but with the vigorous development of Internet (Internet) services, simple calls can no longer meet the requirements of users. Many users hope that the mobile communication system can provide more functions, such as accessing the Internet to query or send information through the mobile phone, organizing video conference calls, and performing remote diagnosis, etc. when nee...
