Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] Embodiment 1 of the present invention provides a GTP-U data forwarding method, which involves a downlink forwarding method of GTP-U data, such as figure 2 As shown, the method includes:

[0054] S11. Call the first callback function at the network driver layer of the main control unit to buffer the received GTP-U data and send it to the GTP layer.

[0055] In the downlink GTP-U data forwarding process, the GTP-U data is first sent to the network drive...

Abstract

The invention discloses a GTP-U (General Tunneling Protocol-User) data forwarding method. The method comprises the following steps of: calling a first call back function to cache the received CTP-U data by a network driving layer of a main control unit and sending the data to a GTP (General Tunneling Protocol) layer; revising a head content of the GTP-U data on the GTP layer to generate PDCP (Packet Data Convergence Protocol) data which accords with the requirements of a PDCP layer and then sending the PDCP data to a baseband processing unit; and calling the first call back function to cache the PDCP data by the network driving layer of the baseband processing unit. The invention further provides a forwarding method of the GTP-U data and the method comprises the following steps of: sending the data received by the baseband processing unit to the main control unit; calling a second call back function to cache the data by the network driving layer of the main control unit and sending the data to the GTP layer; revising the head content of the received data on the GTP layer to generate the GTP-U data needed by the GTP layer and sending the data. With the adoption of the method provided by the invention, the data can be transmitted without entering a protocol stack of a TCP / IP (Transmission Control Protocol / Internet Protocol) and the forwarding speed of the data is improved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a GTP-U data forwarding method. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is also commonly known as 3.9G, which integrates many advanced technologies and excellent system architecture. This technology can improve the data transmission rate in the wireless broadband network and guarantee stable service quality and data throughput, and is regarded as the mainstream technology in the evolution from 3G to 4G. [0003] GTP-U (User plane of GPRS Tunneling Protocol, GPRS Tunneling Protocol User Plane) is an LTE interface user plane protocol, which has Iu-PS user plane data transmission and management functions. In the GTP-U on the side of the LTE base station, the prior art forwards data based on the TCP / IP protocol stack. Take the following data forwarding as an example, figure 1 Shows the specific process of sending GTP-U data from the main contr...
