Problems solved by technology
[0004] In the process of implementing the embodiments of the present invention, the inventors found that in this offloading architecture, the data sending device has a problem of how to determine the data rate of the offloading node device. If the offloading rate is greater than the transmission rate from the offloading node device to the target UE, It will lead to congestion of data packets in the distribution node device, resulting in increased packet delay or even packet loss; conversely, if the distribution rate is lower than the transmission rate from the distribution node device to the target UE, it will lead to waste of resources in the distribution node device
According to the existing technology, the data sending device cannot provide a suitable offloading data rate for the offloading node device

Embodiments of the present invention relate to a data distribution method, a data sending device, and a distribution node device. The data distribution method provided in the embodiment of the present invention includes: obtaining the number of data packets to be distributed buffered in the distribution node device; When the number of data packets is less than the first threshold, the distribution data is sent to the distribution node device, otherwise, the distribution data is not sent to the distribution node device. The data offloading method provided by the embodiment of the present invention can enable the data sending device to provide a suitable offloading data rate for the offloading node device.
Description
technical field [0001] The invention relates to wireless communication technology, in particular to a data distribution method, a data sending device and a distribution node device. Background technique [0002] With the rapid increase of mobile network traffic, in order to make better use of wireless channel resources, the data sending device in the network will distribute the downlink data, part of the downlink data will be sent directly to the target device, and the other part of the data will be sent through the distribution node device to the target device. For example, a long term evolution (long term evolution, hereinafter referred to as: LTE) network may offload part of the downlink data to other inter-frequency wireless networks, such as wireless broadband (wireless fidelity, hereinafter referred to as: WiFi), inter-frequency LTE network, and the like. [0003] Specifically, in an LTE network, an LTE base station directly transmits part of its downlink data to a ta...
