Abstract

The present invention relates to the technical field of network slicing, and specifically discloses a spectrum sharing method for network slicing in a cognitive capacity collection network, including steps: S1: establishing an opportunistic capacity model for spectrum sharing based on the cognitive capacity collection network; S2: based on the The opportunistic capacity model establishes a spectrum sharing model of network slices in the cognitive capacity collection network; S3: solving the spectrum sharing model based on a greedy algorithm to obtain an allocation scheme of authorized channels and an allocation scheme of spectrum sharing. Compared with the existing algorithm, the frequency spectrum sharing method proposed in the present invention can effectively utilize the opportunistic frequency spectrum resource and further improve the channel utilization rate.

Description

technical field [0001] The present invention relates to the technical field of network slicing, in particular to a spectrum sharing method for network slicing in a cognitive capacity collection network. Background technique [0002] In recent years, the demand for wireless applications has increased sharply, so that the wireless communication network not only carries traditional mobile communication services, but also needs to further support more emerging Internet of Things (IoT, Internet of Thing) services. In the future, the wireless communication network will further develop towards a large-scale heterogeneous network oriented to heterogeneous service requirements. In response to this, network slicing came into being, which is considered to be one of the key technologies of the fifth generation (5G, 5Generation) mobile communication system [1] . Network slicing enables mobile network operators to build multiple logical networks on a common physical infrastructure to pr...
