GTP downlink data transmission optimization method and device

Abstract

The embodiment of the invention provides a GTP downlink data transmission optimization method and device. The method comprises the steps of analyzing an obtained first Ethernet data packet; if judgingthat the first Ethernet data packet comprises a first GTP data packet, extracting a tunnel ID and a payload in the first GTP data packet; searching first destination terminal information corresponding to the tunnel ID in the first GTP data packet; and storing the first destination terminal information and the payload in the first GTP data packet in a buffer area. According to the GTP downlink data transmission optimization method and device provided by the embodiment of the invention, the IP protocol stack of the Linux system kernel is logically avoided, and the switching overhead of the kernel mode and the user mode is reduced. After the Ethernet data packet is received, the GTP data is directly processed in the Linux system kernel mode, so that the GTP data processing flow is greatly simplified, the data processing efficiency is improved, and the data transmission rate is further improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile communications, and in particular to a GTP downlink data transmission optimization method and device. Background technique [0002] The data transmission of the current mobile communication network is asymmetrical between uplink and downlink, and users' demand for downlink data is much higher than uplink data, and in the 5G era, downlink data traffic will gradually increase, and higher requirements are put forward for base stations. Therefore, it is imperative to optimize the transmission performance of downlink data. [0003] figure 1 It is a schematic diagram of the uplink and downlink data transmission process of the 5G base station in the prior art, such as figure 1 As shown, the data transmission in the base station is passed up through the physical (Physical, PHY) layer to the medium access control (Media Access Control, MAC) layer, radio link control (Radio Link Contr...

Problems solved by technology

[0005] However, the first solution in the prior art needs to consume a large amount of Linux kernel IP protocol stack resources, the switching overhead of Linux user mode space and kernel space is large, the data processing efficiency is low, and the data transmission rate needs to be improved

The second solution requires that the base station and EPC need to be modified together. In the case where the EPC has been deployed in the live network, adding a base station cannot implement this GTP private protocol solution.
