Heterogeneous network data parallel transmission system and method

Abstract

The invention discloses a heterogeneous network data parallel transmission system. The system comprises a multi-mode terminal, an aggregation server and a transmission control unit; the multi-mode terminal comprises an LTE wireless network card and a WiFi access wireless network card; the aggregation server provides LTE mobile cellular access and wifi access for the multi-mode terminal at the same time; the transmission control unit is used for periodically detecting each physical link bandwidth, shunting according to a detected bandwidth proportion and moreover sorting received service data packets by using a receiving window. Correspondingly, the invention also provides a downlink transmission method and uplink transmission method based on the system. According to the system and the methods, the problem that a relatively high transmission rate cannot be realized by a single access technique because of limitations of factors such as bandwidths is solved; the advantages of two access techniques are utilized fully; parallel transmission between the two access techniques is realized; and therefore, the total transmission rate of the data is greatly increased, and the pursuit of a user for high rate transmission is satisfied.

Description

technical field [0001] The invention belongs to the field of mobile communication technology and wireless local area network technology, and more specifically relates to a heterogeneous network data parallel transmission system and method. Background technique [0002] At present, due to the rapid development of multimedia technology and the rapid popularization of mobile terminals such as smartphones and tablet computers, users are pursuing higher and higher Internet access speeds. However, due to the scarcity of frequency resources and the extreme use of various new technologies, it is very difficult to further increase the transmission rate quickly. A single access network technology is far from satisfying users' pursuit of high transmission rates. [0003] At the same time, due to the rapid development of wireless technology in recent years, a large number of mobile cellular base stations and wifi access points have been widely deployed, overlapping coverage, and often a...
