Abstract

The invention discloses a multi-access heterogeneous network downlink energy-saving transmission method, mainly for solving the problem of incapability of guaranteeing user experience and reducing energy consumption of large-capacity transmission service by use of a conventional turn-off energy conservation technology. The realization steps are as follows: (1), negotiating all available networks with a multimode terminal and ordering the available networks; (2), determining whether energy-saving concurrent transmission needs to be carried out; (3), selecting an optimum network set for participating in the concurrent transmission according to user needs and network states; (4), calculating an optimum transmission rate for minimization of total power consumption; (5), calculating an optimum shunting proportion according to the optimum transmission rate; and (6), carrying out the concurrent power-saving transmission by use of the proportion. The method provided by the invention has the advantage of provable minimum total transmission power consumption.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a downlink energy-saving transmission method of a multi-access heterogeneous network. Background technique [0002] With the continuous development of wireless networks and the increase of transmission rate, various emerging multimedia services (such as high-definition video services) are rapidly popularized, and the user's demand for high-speed and large-capacity transmission services has increased sharply, resulting in increasing energy consumption of equipment. At present, the information and communication technology industry has become the fifth largest energy-intensive industry, and its energy consumption accounts for 2%-6% of the global total energy consumption, resulting in greenhouse gas emissions accounting for 2% of the global total emissions. On the other hand, although wireless network bandwidth is growing rapidly, the profit of operators is growing slo...
