Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] Under a certain delay constraint, the energy consumption of the multi-mode terminal in parallel transmission of data over multiple channels should be minimized, that is, the sum of the transmission power of the multi-mode terminal on each wireless access network channel should be minimized. It can be seen from the large-scale fading transmission model that the minimum sum of the transmission power of the multi-mode terminal on each wireless access network channel is equivalent to the minimum sum of the reception power of each wireless access network base station. According to the Shannon formula, the receiving power of the wireless access network base station is rel...

Abstract

The invention discloses a traffic distribution method for multi-channel parallel communication of a multi-mode terminal in the technical field of communication. First, network parameters of a wireless network are detected, secondly, a data transfer rate of the multi-mode terminal is detected, finally, the number of data packages sent within distributed unit time of wireless access network channels is calculated, and data traffic is distributed to the wireless access network. According to the traffic distribution method for the multi-channel parallel communication of the multi-mode terminal, on the premise that smooth transmission of network data is guaranteed, an energy utilization rate of the multi-mode channel can be furthest improved.

Description

technical field [0001] The present invention relates to a flow distribution method for a multi-mode terminal when using multiple wireless access networks for network communication at the same time, and in particular to a method in the field of communication technology in which a multi-mode terminal simultaneously uses multiple A traffic distribution method for network communication in a wireless access network. Background technique [0002] With the widespread use of 2G, 3G cellular wireless networks, WLAN and WiMax all over the world, the next generation wireless network will be a heterogeneous network in which multiple wireless networks coexist. That is to say, the trend of future mobile communication development is no longer that one technology dominates the world, but that multiple wireless technologies coexist and complement each other to provide diversified access services and realize seamless mobility. At the same time, the development of terminal technology allows a...
