Problems solved by technology

Although the above method can realize the transmission of data services at the IP Abis interface, because the packet data service is transmitted at the Abis interface, the PCU frame structure is adopted, and the upper layer processing protocol of the PCU frame does not use a line control protocol (RLC, Radio Link Control). The window mechanism has a certain degree of fault tolerance, and can sort the PCU load in the PCU frame. Therefore, compared with the voice service, the packet service is not sensitive to disorder and jitter, and the RTP buffer processing mechanism will cause a large System delay and network resource waste
Therefore, there is currently no transmission method for packet data services that is fully applicable to the IP Abis interface

Embodiment Construction

[0028] The basic idea of ​​the present invention is: set up the PCU frame based on the Abis interface protocol stack structure of UDP, and encapsulate more than one PCU frame in a UDP / IP protocol frame, and adjust the frame number jitter and disorder in the transmission process , improve the anti-jitter performance of the system.

[0029] It should be noted that the structure of the PCU frame includes the following composition methods: one composition method is that the frame number information and user data are respectively stored in different frames, such as the PCU synchronization frame used for frame number synchronization and the frame number carrying data block PCU data frame; another composition method is that frame number information and user data are in the same PCU frame, for example, a PCU frame includes a PCU frame header and a PCU payload.

[0030] In order to make the above objects, features and advantages of the present invention more comprehensible, the present...

Abstract

A system for the packet data transmission is provided by the present invention, which includes: a base transceiver station (BTS) and a base station controller (BSC). Correspondingly a method for the packet data transmission is also provided by the present invention, which includes: the BTS builds a packet control unit (PCU) frame and encapsulates the built PCU frame as a network protocol frame according to the carrier frequency, and transmits the network protocol frame to the BSC; the PCU frame is parsed by the BSC from the network protocol frame, and the PCU load is parsed from the PCU frame and the parsed PCU load is ordered, and the ordered PCU load is selected, and then the BSC builds a logical link control frame and transmits it to a core network. Therefore, the present invention can optimize the system delay and implement the reliable transmission.

Description

technical field [0001] The invention relates to packet data transmission technology in the field of wireless communication, in particular to a packet data transmission system and method. Background technique [0002] Global System for Mobile Communication (GSM, Global System for Mobile Communication) is the most widely used communication system in mobile communication, and the wireless access network equipment of GSM is usually called Base Station Subsystem (BSS, Base Station System). The role played by the BSS in GSM mainly includes: on the one hand, the BSS is connected with the mobile terminal (MS, Mobile Station) through the wireless network, and performs wireless signal transmission, reception and wireless resource management; on the other hand, the BSS and the mobile switching center (MSC, MobileSwitching Center) or mobile switching center server (MSC Sever, Mobile Switching CenterSever) is connected to realize the communication connection between MSs, or between MSs a...
