Problems solved by technology

[0015] The technical problem to be solved by the present invention is to provide a data processing method for the packet service data transmission link of the terminal wireless communication system, so as to solve the problem of how to minimize the gap between the layers of the data link when designing and implementing the terminal protocol stack software. The copy operation, the optimal effect is to allocate and release the memory only once on the uplink and downlink data links, and make the number of data copies between each layer of the protocol data link zero

Abstract

The disclosed data process method for grouping business data transmission link in terminal wireless communication system comprises process ways both on transmitting and receiving data. This invention needs no copy during transmitting data on different protocol layers, reduces consumption on memory and CPU clock, and improves data transmission capacity and speed.

Description

technical field [0001] The present invention relates to a data processing method for a packet service data transmission link of a terminal wireless communication system, in particular, the present invention relates to a method for memory management and data transfer of a packet service transmission link in a wireless communication system protocol software implemented by a terminal . Background technique [0002] Wireless communication systems include GSM / GPRS / EGPRS systems, TD-SCDMA systems, and WCDMA systems. Packet service data refers to IP data packets. [0003] In the prior art, the GPRS protocol in the GSM system is mainly used as an example (EGPRS is the same as the GPRS in the protocol framework) for specific description, and the present invention is also applicable to other wireless communication systems. The general packet radio service (GPRS) is layered on the data service link. The protocol layer data link is divided into SNDCP (Subnetwork Dependent Convergence...
