Abstract

The invention relates to long-term evolution (LTE) data surface software architecture, which runs on a multi-core processor hardware platform. The LTE data surface software architecture comprises a packet data convergence protocol (PDCP) software module for executing one or more of encryption / decryption, compression / decompression and completeness checking operation on a data packet, a radio link control (RLC) software module for unpacking, segmenting or serially connecting, resequencing and recombining data, and a multi-access control (MAC) software module for multiplexing or demultiplexing the data of a logic channel, scheduling each logic channel group packet and transmitting and receiving the data, wherein each software module of the software architecture independently runs on any processor kernel in the multi-core processor. By a distributed structure, the software modules of the software architecture are distributed on multiple processor kernels and are optimized, so that the execution efficiency of an LTE data surface streamline 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 device. Background technique [0002] LTE is the evolution of 3G. It improves and enhances the air access technology of 3G, adopts OFDM (Orthogonal Frequency Division Multiplexing) technology and MIMO (Multiple-Input Multiple-Out-put, multiple input multiple output) 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-UTRA...
