Abstract

The invention relates to a long term evolution (LTE) data plane software architecture, the software architecture runs in a multi-core processor hardware platform, and the software architecture comprises a PDCP software module which is used for finishing one or more operations of encryption / decryption, compression / decompression and integrity verification operations of a data packet; an RLC softwaremodule used for completing the operations of data unpacking, segmenting / series connection, reordering, recombining and the like; a MAC software module used for completing multiplexing / demultiplexingof data comprising logic channels, and scheduling each logic channel group package and data receiving and transmitting operation; Each software module of the software architecture runs on any one processor core in the multi-core processor independently. By adopting a distributed structure, software modules of the software architecture are distributed on a plurality of processor cores for operation, and the software modules are optimized, so that the execution efficiency of an LTE data surface assembly line is improved.

Description

technical field [0001] The present invention relates to third-generation mobile communication LTE (Long Term Evolution, long-term evolution) technology, in particular to an LTE data plane software architecture. Background technique [0002] LTE is the evolution of 3G. It improves and enhances the air access technology of 3G. It adopts OFDM (Orthogonal Frequency Division Multiplexing) technology and MIMO (Multiple-Input Multiple-Out-put) technology. Under the 20MHZ spectrum bandwidth, it can provide uplink 50Mbps and downlink 100Mbps peak rate, which improves the performance of cell edge users, improves cell capacity and reduces system delay. [0003] figure 1 It is a schematic diagram of an LTE system network architecture in the prior art. shown figure 1 As shown, the entire LTE system consists of three parts: core network (EPC), base station (eNB) and user equipment (UE). Among them, the eNB is responsible for the access network part, also known as E-UTRAN; the EPC is r...
