Data concurrence transmission method based on cross-layer optimization in wireless heterogeneous network system

Abstract

The invention relates to a data concurrence transmission method based on cross-layer optimization in a wireless heterogeneous network system. The data concurrence transmission method based on cross-layer optimization in the wireless heterogeneous network system comprises the following steps: a gateway is defined as an assembling point of a plurality of wireless heterogeneous networks which are assembled between a server and a terminal; a new protocol layer, namely a cross-layer processing layer, is built between a network layer and a data link layer of the gateway, and meanwhile, a visual interface card is built on the cross-layer processing layer; when data transmitted from the server arrives at the gateway, an internet protocol (IP) data package is abstracted from the network layer of the gateway, and meanwhile, information channel quality information of each wireless heterogeneous network is detected by the gateway; and the IP data package to be sent is allocated to the each wireless heterogeneous network by the cross-layer processing layer according to detection results and is sent to terminal equipment; the terminal receives the data, puts the received IP data package into a receiving buffering area, and conducts reordering and processing routines on the IP data package in the buffering area. The data concurrence transmission method based on cross-layer optimization in the wireless heterogeneous network system can increase end-to-end transmission speed of the network, reduce service end-to-end transmission delay, and achieve equalization transmission of concurrence data in the wireless heterogeneous network system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a data concurrent transmission method based on cross-layer optimization in a wireless heterogeneous network system. Background technique [0002] In recent years, wireless communication technology has made great progress, and various new wireless communication concepts and technologies emerge in an endless stream, forming a wireless heterogeneous network with multiple systems coexisting. At the same time, with the rapid development of mobile Internet and communication technology, people's quality of life is gradually improving, and diversified smart terminals are becoming popular. People's demand for the capacity, speed, flexibility and quality of communication networks is increasing day by day. Due to the low end-to-end throughput and high delay, the network can no longer meet the existing needs, and many cellular network providers are beginning to feel very anxious about t...

However, in the past, the research on joint radio resource management mainly focused on the selection of specific networks when providing services, so as to take advantage of the technical advantages of a single network. Although the situation of other networks in heterogeneous network environments was also considered, as a joint The multi-mode or reconfigurable technology, which is one of the foundations of radio resource management, has not been fully utilized. Technically, with the support of multi-mode technology or reconfigurable technology, terminals with multiple sets of antennas have the ability to simultaneously access the The ability of multiple wireless access networks, thus a new concept of wireless resource management emerges: to divide a single service data flow, and transfer the sub-data flow to multiple networks for parallel transmission
