Description

Data scheduling method, device and system

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a data scheduling method, apparatus, and system. Background technique

In order to alleviate the congestion of the wireless mobile communication network, part of the data in the wireless mobile communication network may be offloaded to other supplementary networks such as Wireless Fidelity (WiFi) for offloading, that is, a part of the data of the user equipment is directly moved by wireless. The air interface of the communication network is transmitted, and the other part of the data is transmitted through the supplementary network.

In the prior art, when the user needs to be offloaded through the WiFi network, the user needs to manually set the WiFi on the user equipment side; and when the user equipment has the uplink data transmission, the communication resource needs to be contending. The specific competition rule is: the user equipment detects the transmission channel. If the transmission channel is busy, the user equipment continues to perform transmission channel detection until the transmission channel is idle and the idle time is greater than the distributed interframe space, the user equipment enters a contention window; in the contention window, the user equipment sets a random time, Before the random time expires, if the transmission channel is always idle, the competition succeeds after the random time expires, and the user equipment starts to send data to the access point device (Access Point, AP); if the transmission channel is busy before the random time expires , indicating that the competition failed, and continues to detect the transmission channel. Therefore, when the transmission channel of the WiFi is busy, the user equipment is always in the transmission channel detection, and the uplink data cannot be transmitted. In order not to affect the data transmission, the user needs to manually cancel the WiFi on the user equipment side to use the air interface of the wireless mobile communication network. For data transmission, not only the user experience is poor, but also the data transmission efficiency of the WiFi network is low.

Further, when there are multiple user equipments in the WiFi network, it is possible that multiple user equipments have the same random time set in the competition, and multiple user equipments simultaneously send uplink data to generate data collisions, resulting in multiple user equipments.
