Method for realizing optimization of point-to-point protocol data transmission of mobile communication wireless Modem terminal

Abstract

The invention relates to a method for realizing the optimization of point-to-point protocol data transmission of a mobile communication wireless Modem terminal. Data transmission processing performed on a wireless Modem by terminal equipment comprises that: the terminal equipment performs PPP encapsulation on a downlink data packet; a terminal equipment side driver layer performs analysis and UDF encapsulation on the data packet and transmits the data packet to the Modem; and the Modem side driver layer performs UDF analysis and subsequent processing on the data packet; and the data transmission processing performed on the terminal equipment by the wireless Modem comprises that: the Modem performs the UDF encapsulation on an uplink data packet on a driver layer, and transmits the data packet to the terminal equipment; a terminal equipment side driver performs the UDF analysis and the PPP encapsulation on the data packet; and a PPP layer performs the analysis and the subsequent processing on the data packet. The method for realizing the optimization of the point-to-point protocol data transmission of the mobile communication wireless Modem terminal reduces the CPU occupancy rate of a Modem terminal, saves hardware system resources, has stable and reliable working performance, and can be widely suitable for a second generation mobile communication system and a third generation mobile communication system.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to the technical field of mobile communication terminals that can be used as Modem equipment, and specifically refers to a method for realizing the optimization of point-to-point protocol data transmission of wireless Modem terminals in mobile communication. Background technique [0002] Modern communication is developing in the direction of broadband, intelligence, personalization and business integration. In order to meet people's increasing demand for communication speed, the second-generation wireless mobile communication system represented by GSM is transitioning to the third-generation wireless mobile communication system represented by WCDMA at a very fast speed around the world. [0003] The speed of the wireless Modem terminal is also increasing continuously. Taking WCDMA (with HSDPA) data card as an example, the downlink rate is getting closer to the theoreti...

Problems solved by technology

Therefore, traverse all the contents of the data packet on the Modem side, calculate the FCS, send it to the PC through the physical link, traverse it again on the PC side, and calculate the FCS to judge the correctness of the packet. For the Modem terminal, this method is The efficiency and performance are very low, unable to meet the needs of high-speed data transmission, and will increase the input-output ratio, thereby increasing the hardware design and manufacturing costs, which is not conducive to the promotion and application of mobile communication technology
