AI Technical Summary

Technical Problem

Existing technologies require two copies during data transmission, which significantly impacts system performance.

Method used

By encrypting the data in the AP system memory directly at the PDCP layer, the first data copy is avoided, and the AP system memory usage is notified after encryption, thus reducing the number of memory copy operations.

Benefits of technology

It improves data transmission efficiency, reduces DDR bandwidth usage, lowers CPU load, and enhances system stability and reliability, especially significantly improving system performance in high-throughput environments.

Abstract

This application provides a method for processing IP data, a PS system, a medium, and a system. The method for processing IP data includes: receiving an IP data address sent by an AP system, and encrypting the IP data using a PDCP layer based on the IP data address to obtain encrypted data. The memory used during the PDCP layer encryption of the IP data is the AP system's memory. A first memory usage completion message is generated and sent to the AP system, and the encrypted data is sent to the network side via the physical layer. The memory used during the transmission of the encrypted data to the network side via the physical layer is the PS system's memory. This solves the problem that existing technologies require two copies during data transmission, which significantly impacts system performance.
