Data transmission method and device based on multiple system networks

Abstract

The invention provides a data transmission method and a data transmission device based on multiple system networks. By the method, data packet sending rates suitable for air interface states of a first system network and a second system network are determined by detecting the air interface states of the first system network and the second system network; data packets are distributed to the first system network and the second system network according to the determined data packets, so that the data packets can be jointly transmitted to users through the two system networks; the bandwidths of the first system network and the second system network are fully used; the data transmission rate is increased; moreover, by detection of the air interface states of the system networks, the data transmission rates of multiple system networks can be flexibly and dynamically adjusted; and the data transmission reliability is improved.

Description

Technical field [0001] The present invention relates to communication technology, in particular to a data transmission method and device based on a multi-standard network. Background technique [0002] At present, more and more operators have deployed multi-standard networks, and multi-mode base stations have become the mainstream choice. However, in the prior art, in a multi-mode base station, services of different standards run independently, so that data services can only be transmitted on a network of one standard at a time. Although the network of the selected standard usually has a higher data transmission rate, when the air interface link status of the network of the selected standard is not good, the data transmission rate of the network of this standard will decrease. The air interface link status of the selected standard network has not reached the set threshold, which will result in the inability to switch data services to another standard network with better air inte...

Problems solved by technology

However, in the prior art, in the multi-mode base station, services of different standards run independently, so that data services can only be transmitted on a network of one standard at the same time

Although the network of the selected standard is usually a standard with a high data transmission rate, when the air interface link status of the network of the selected standard is not good, the data transmission rate of the network of this standard will drop, and at this time, due to If the air interface link status of the selected standard network does not reach the set threshold, the data service cannot be switched to another standard network with better air interface link status, higher data transmission rate, and relatively idle

As a result, the air interface resources of the relatively idle network of another standard cannot be fully utilized
