Method for transmitting two-layer data in LTE system

Abstract

The invention discloses a method for transmitting two-layer data in an LTE system. The method can be used for realizing completely transparent transmission service transmission of the two-layer data between a terminal and a service network without changing the existing network deployment or network plan of users in the industry, simply changing information transmitted in a standard LTE access process and enhancing the two-layer processing ability of a PDN gateway to realize the wireless transparent transmission of the two-layer data between the terminal and the service network by transparently adding the LTE system without changing the network deployment or the network plan of the users, and meeting the data transmission demands in specific industrial fields, and meanwhile, by means of the transparent processing, the method can be used for greatly avoiding the transmission efficiency and processing efficiency problems caused by replacing a data MAC address via the PDN gateway.

Problems solved by technology

However, the standard LTE system is based on a layer-3 data transmission network. The terminal service data packets transparently transmitted by the system only support parsing and transmission of data packets containing layer-3 or above information such as IP addresses, but cannot process data containing layer-2 information such as MAC addresses. Bag

In addition, the LTE system cannot obtain the MAC address of the terminal itself and the source MAC address detection strategy of the standard layer 2 protocol stack will cause the standard LTE system to be unable to replace the terminal to provide the data packet containing the terminal layer 2 MAC address to the service network. Add the MAC address of the PDN gateway in the standard way, which will eventually lead to the failure of business data transmission and data verification

Similarly, the data packet delivered by the LTE system to the terminal cannot contain the planned MAC address of the terminal, which will cause the terminal to discard the obtained data packet
