Resource distribution method under heterogeneous network fusion

Abstract

A resource distribution method under heterogeneous network fusion comprises the steps of 1 initializing the system parameters, distributing the user ends (UE) of the wired backhaul bandwidth and overlapping area to each radio access network (RAN) averagely, and setting the number of the wireless channels distributed to each RAN as 0; 2, determining the distribution strategy of a first channel resource, adding a wireless channel to each RAN, solving a time delay reduction problem about the wireless channels, the wired bandwidth and the user access, obtaining the RAN subscript i* corresponding to the channels, and distributing the wireless channels to the No.ix RAN; 3 determining the distribution strategy of the residual wireless channels, taking the step 2 as reference to obtain the RAN corresponding to the wireless channels, distributing the channels to the corresponding RAN; 4 updating the system parameters, distributing the wireless channels to the RAN according to the optimal distribution strategy obtained in the step 2, distributing the UE of the overlapping area to each RAN averagely, and setting the number of the wired bandwidth units distributed to each RAN as 0.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a resource allocation method under the fusion of heterogeneous networks. Background technique [0002] With the rapid growth of business requirements and the rapid development of mobile communication and information technology, a variety of wireless access technologies have emerged. Most mobile terminals are equipped with multiple radio interfaces to access different Radio Access Networks (RAN), such as cellular network, Wi-Fi, Bluetooth, etc. HetNet has become the trend of wireless network development in the future. Different wireless networks are heterogeneous in terms of access technologies, terminals, and services, which makes it difficult to integrate different networks. In order to achieve the goals of supporting massive low-power device access under HetNet, expanding coverage, improving reliability, and reducing latency, designing resource allocation st...

Problems solved by technology

However, the complexity of this technology is high, and the calculation power consumption is large. When it comes to specific decision factors such as network delay, network reliability, and user friendliness, no actual formula is given, but it is defined based on experience.

In the case of limited cost, this will obviously bring a greater burden to the user's overhead
