Problems solved by technology

[0006] But, in the current GPRS network layout, BSS (base station subsystem; Base Station Subsystem) and SGSN (service GPRS support node; Servicing GPRS Support Node), and network server are often located in different cities or regions, so BSS (for example, including BSC ( The transmission network of the GB interface (Interface between BSS and 2G SGSN) between the BaseStation Controller (base station controller)) and 2G (2nd Generation; second generation) SGSN integrates various transmission media, resulting in frequent loss of the GB interface transmission network. packet phenomenon
The FTP transmission protocol is a transmission protocol with a strict TCP (Transmission Control Protocol; Transmission Control Protocol) confirmation mechanism. All transmitted data blocks need to be confirmed by the peer. Once there is a packet loss caused by transmission, because the confirmation mechanism of the TCP layer will cause subsequent generate a series of retransmissions

Abstract

The embodiment of the invention provides a data packet retransmission control method and data packet retransmission control network side equipment. The method is executed by the network side equipment, and comprises the following steps of: receiving data packets from a server; acquiring serial number information carried by the data packets from the data packets; detecting the continuity of the data packets according to the serial number information; and performing data packet retransmission control according to the continuity of the data packets. The embodiment of the invention can earlier and more quickly detect the loss of the data packets, perform corresponding retransmission control in advance, shorten retransmission time delay and solve the problem of data transmission traffic stoppage caused by overlong time delay.

Description

technical field [0001] The embodiments of the present invention relate to the field of data communication, and more specifically, relate to a method and network side equipment for data packet retransmission control. Background technique [0002] Global System for Mobile Communication (GSM for short) is a standard launched by the European Standardization Committee in 1992. It adopts digital communication technology and unified network standards to ensure communication quality, and can develop more of new services for users to use. [0003] General Packet Radio Service ("GPRS" for short) is a mobile packet data service developed on the basis of the existing GSM mobile communication system. GPRS introduces the functional entity of packet switching in the GSM digital mobile communication network to complete data transmission in packet mode. [0004] The Enhanced GPRS service (Enhanced GPRS, "EGPRS" or "EDGE") system can be regarded as performing modulation algorithm evolution ...
