Combined type dynamic spectrum distribution method in heterogeneous network convergence scene

Abstract

The invention discloses a combined type dynamic spectrum distribution method in a heterogeneous network convergence scene. The combined type dynamic spectrum distribution method in the heterogeneous network convergence scene specifically comprises the following steps of: (1) collecting a spectrum resource of each wireless communication network to form a vector spectrum resource library; (2) establishing a combined type dynamic spectrum distribution universal model for the vector spectrum resource library according to a spectrum distribution optimizing strategy of firstly optimizing inter-network spectrum distribution and then performing secondary optimization on inner-network spectrum after the inter-network spectrum distribution is optimized; (3) obtaining a combined type dynamic spectrum distribution model by using an artificial intelligence method. The combined type dynamic spectrum distribution method in the heterogeneous network convergence scene gives consideration to collaborative distribution optimization problem of spectrum resources among networks and in the networks in the aspect of improving the spectrum resource utilization rate of a whole heterogeneous network system, provides powerful support for development of green communication and can find an optimal spectrum optimal distribution scheme.

Description

technical field [0001] The invention relates to a joint dynamic spectrum allocation method in a heterogeneous network fusion scenario, which solves the problem of shortage of mobile communication network spectrum resources by jointly optimizing and allocating spectrum resources in a heterogeneous communication network fusion scene. Background technique [0002] At present, with the continuous growth of wireless communication services, wireless spectrum resources become very scarce, making it difficult to develop new services. The existing spectrum management system allocates spectrum to registered authorized users, and unlicensed users cannot use the allocated frequency bands regardless of whether the authorized users use it or not. The disadvantage of this spectrum allocation mechanism is: in the state of shortage of spectrum resources, unlicensed users cannot use the idle spectrum resources of licensed users, resulting in waste of spectrum resources. [0003] In the futur...

Problems solved by technology

[0006] Disadvantages of the existing technology: 1. In most cases, a static spectrum allocation scheme is adopted. In a state of shortage of spectrum resources, unlicensed users cannot use the idle spectrum resources in the hands of licensed users, resulting in waste of spectrum resources; 2. In some hotspot areas, some operators adopt a dynamic spectrum allocation scheme to maximize the spectrum resources they own from the perspective of a single wireless network, but do not consider the spectrum allocation of other wireless networks. On the whole, The utilization rate of spectrum resources is not high; 3. Based on manual calculation or based on the experience and knowledge of engineering personnel, only a feasible spectrum allocation scheme is given. The spectrum allocation cost is high and the response speed is slow, so it is difficult to adapt to solve large-scale The dynamic spectrum allocation problem for
