Description

数据调度方法及装置、 系统  Data scheduling method, device and system
技术领域 Technical field
本发明实施例涉及通信技术领域, 尤其涉及一种数据调度方法及装 置、 系统。 背景技术  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
为了缓解无线移动通信网络的拥塞, 可以采用将无线移动通信网络中 的部分数据分流到例如无线保真 (Wireless Fidel ity, WiFi ) 等其他补 充网络进行分流, 即用户设备的一部分数据直接用无线移动通信网络的空 口进行传输, 另一部分数据通过补充网络进行传输。  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.
在现有技术中, 当需要通过 WiFi网络分流时, 需要用户在用户设备侧 手动设置 WiFi ; 且当用户设备有上行数据传输时, 需要竞争传输资源, 具 体的竞争规则为: 用户设备检测传输信道, 若传输信道忙, 则用户设备持 续进行传输信道检测, 直至检测到传输信道空闲且空闲时间大于分布式帧 间间隔, 则用户设备进入竞争窗口; 在竞争窗口内, 用户设备设置一个随 机时间, 在随机时间超时之前, 如果传输信道一直处于空闲, 则随机时间 超时后竞争成功, 用户设备开始发送数据给接入点设备 (Access Point , AP ) ; 如果在随机时间超时前, 检测到传输信道忙, 则说明竞争失败, 继 续检测传输信道。 因此, 当 WiFi的传输信道忙时, 用户设备一直处于传输 信道检测中, 不能进行上行数据的传输, 为了不影响数据传输, 用户需要 在用户设备侧手动取消 WiFi , 才能用无线移动通信网络的空口进行数据传 输, 不仅用户体验度较差, 而且 WiFi网络的数据传输效率较低。  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.
进一步地, 当 WiFi 网络中存在多个用户设备时, 有可能多个用户设 备在竞争中设置的随机时间相同, 则多个用户设备会同时发送上行数据从 而产生数据碰撞, 造成多个用户设备的数据传输失败, 降低了 WiFi 网络 的数据传输效率。 发明内容 本发明提供一种数据调度方法及装置、 系统, 能够降低数据碰撞的概 率, 提高 WiFi网络的数据传输效率。 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. Data transmission failure, reducing the data transmission efficiency of the WiFi network. Summary of the invention The invention provides a data scheduling method, device and system, which can reduce the probability of data collision and improve the data transmission efficiency of the WiFi network.
