Embodiment 1
[0095] Based on the above description, if figure 2 As shown, the resource allocation method for improving network quality in a multi-slice network provided by the present invention includes the following steps:
[0096] 1) Slice the heterogeneous network to be tested according to the user's business needs, and model the resource allocation problem that affects the network quality of each slice, and establish a resource allocation model for each slice, specifically:
[0097] 1.1) According to user service requirements, the heterogeneous network to be tested is sliced into rate-priority slices and delay-priority slices.
[0098] 1.2) Set the resources that tenant 1 uses to control rate-first slicing, and tenant 2 that controls the resources that delay-priority slicing. Aiming at the problem of resource allocation that affects the network quality of each slice, with the goal of scoring the network services of the two tenants, establish each The slice corresponds to the non-co...
Embodiment 2
[0206] This embodiment provides a resource allocation system for improving network quality in a multi-slice network, including:
[0207] The resource allocation model building module is used to slice the heterogeneous network to be tested, and model the resource allocation problem that affects the network quality of each slice, and establish the resource allocation model of each slice;
[0208] An approximate convex function determination module is used to process non-convex functions in each resource allocation model to obtain an approximate convex function of each resource allocation model;
[0209] The continuous convex approximation module is used to solve the approximate convex objective function of the resource allocation model of each slice by using the continuous convex approximation algorithm under the condition that the tenants corresponding to each slice equally share the total subcarriers, and determine the Optimal slice resource allocation strategy and scoring cri...

Abstract
The invention relates to a resource allocation method and system for improving the network quality in a multi-slice network, and the method is characterized in that the method comprises the followingsteps: 1) slicing a to-be-tested heterogeneous network, and building a resource allocation model of each slice; 2) obtaining an approximate convex function of each resource allocation model; 3) underthe condition that the tenant corresponding to each slice equally divides the total subcarriers, solving an approximate convex objective function of each slice resource allocation model by adopting acontinuous convex approximation algorithm according to the number of the subcarriers of each slice, and determining an optimal slice resource allocation strategy and a scoring standard of each slice;4) under the condition that the tenant corresponding to each slice does not equally divide the total subcarrier, solving the approximate convex objective function of each slice resource allocation model by adopting a non-cooperative game method according to the number of subcarriers of each slice, determining the optimal slice resource allocation strategy and scoring standard of each slice, and the method can be widely applied to the technical field of network quality evaluation.
Description
technical field [0001] The invention relates to a resource allocation method and system for improving network quality in a multi-slice network, and belongs to the technical field of network quality assessment. Background technique [0002] The comprehensive index evaluation of the communication network is mainly composed of the overall network utility quality and the network comprehensive performance score. The overall network utility quality evaluation index reflects the utility value of the current network from the perspective of network quality, avoiding the tedious work of checking indicators one by one; the network comprehensive performance The score combines various types of network indicators through normalization to present the performance of all aspects of the network, which can speed up the positioning of specific KPIs (key performance indicators) that affect network quality. [0003] At present, there has been some research on the performance evaluation of the net...
