Abstract

The embodiment of the invention discloses a data scheduling method and device for a narrowband Internet of Things. The embodiment of the invention provides a technical scheme. The method comprises thesteps: determining a scheduling type through a base station MAC layer based on an object needing to be scheduled of a current service; issuing a corresponding scheduling subframe according to the scheduling type, monitoring the corresponding scheduling subframe by the terminal MAC layer according to the attachment state of the terminal MAC layer and the real-time service requirement, and allocating channel transmission resources to uplink data according to the weight of each service type in the scheduling subframe. By adopting the technical means, the adaptive scheduling of the narrow-band Internet of Things can be realized, the conditions of network bandwidth occupation and air interface channel resource shortage are avoided, and the data scheduling and transmission efficiency is optimized. Besides, channel transmission resources are allocated through a terminal MAC layer, network data scheduling is further optimized, and the utilization rate of network bandwidth is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular to a data scheduling method and device for narrowband Internet of Things. Background technique [0002] With the diversification of communication network types and the development and progress of communication technology, at present, the transmittable bandwidth of communication network is also becoming larger and larger, and the rate of data transmission is getting faster and faster. However, in the high When bandwidth communication technology is applied to some specific devices that require low speed, low cost or even low power (such as smart meters, sensor detection, etc.), it is easy to cause waste of bandwidth resources. Therefore, there is an existing narrowband Internet of Things technology, which supports cellular data connections of low-power devices in a wide area network, and has the characteristics of small communication bandwidth, l...
