Embodiment

[0030] The operating environment of this embodiment is in the base station operation and maintenance management terminal BSM3000, which is used to realize the remote upgrade of the control program, and in the wireless data transmission product TCMK-GC, which is used to realize the file transmission function.

[0031] In this embodiment, a single-chip microcomputer system-based data stream breakpoint resume transmission method is based on the TCP or UDP basic transport layer protocol of the single-chip microcomputer system, and the carrier in the form of "frame" is used as the basic unit of data transmission, and the time slice rotation algorithm is adopted. , to achieve "concurrent" transmission of data, such as figure 1 shown, including the following steps:

[0032]Step 1, split the data stream into multiple data packets according to the size, and then encapsulate the data packets into "frames". "Frame" refers to the data packets sent each time, which is the smallest unit of ...

Abstract

The present invention discloses a single-chip microcomputer system-based data stream breakpoint continuation method, based on the TCP or UDP basic transport layer protocol that the single-chip microcomputer system usually has, by using the "time slice rotation algorithm" to simulate the realization of multi-threading, using "frame "As the basic unit of data structure, it achieves or is close to the effect of continuous transmission of data streams in the computer field, eliminates the high bit error rate in the transmission process, improves the transmission efficiency of data streams, reduces transmission time and network traffic, and reduces communication costs.

Description

technical field [0001] The invention relates to the field of single-chip computer system network communication, in particular to a single-chip computer system-based data stream breakpoint resume transmission method. Background technique [0002] Breakpoint resuming refers to dividing the downloaded or uploaded data stream into several parts, and each part uses a separate thread for uploading or downloading. When a network failure occurs, the uploading and downloading can be continued from the part that has already been uploaded or downloaded. Thus, the network transmission time can be saved and the transmission rate can be increased. In the absence of the support of continuous transmission technology, the data transmission efficiency and speed depend on the network conditions and the size of the data flow, especially in the wireless network application environment (such as GPRS, CDMA, Zigbee and VHF / UHF ultrashort wave wireless communication), When the network signal cannot...
