Base station user plane data processing and optimizing method based on Linux system

Abstract

The invention provides a base station user plane data processing and optimizing method based on a Linux system. The method comprises the steps as follows: package classification is completed by using a package processing acceleration module; the interrupt of package reception is reduced in an intelligent switching manner for interrupt polls; memory copying is avoided by using a core space-user space memory mapping technology; and context switching between a core state and a user state is reduced by using a lock-free queue technology, so that the performance for processing base station user plane data is remarkably improved.

Description

technical field

[0001] The invention relates to the technical field of wireless communication, in particular to a Linux system-based base station user plane data processing optimization method. Background technique

[0002] With the advancement of wireless communication technology, the requirements for user plane data processing of LTE (3GPP Long Term Evolution) base stations, especially in the downlink direction, are getting higher and higher. LTE base station user plane data is mainly GTPU (Tunneling Protocol) service carried on UDP (User Datagram Protocol). The traditional processing method is to use the network card to receive the message, and the network card notifies the Linux kernel through an interrupt, and the Linux kernel passes through the network The layer-by-layer processing of the protocol stack, for GTPU business, includes the Ethernet layer, IP (Internetwork Interconnection Protocol) layer, UDP layer, Socket (network socket) layer, wakes up the user mode prog...
