Service Resource Control Method in Heterogeneous Network Convergence System

Abstract

The invention provides a service resource control method in a heterogeneous network convergence system. The method comprises the specific steps that an FBS firstly divides fixed QoS restrain service users and variable QoS restrain service users according to user service types and records QoS requirements of all users; then the FBS carries out power distribution according to division of the user sets of different types and different service user QoS restrain values, on the basis of guaranteeing quality of the Femtocell fixed service users and quality of the variable service users, resource equitable distribution optimization is carried out on the FBS in order to maximize the Nash bargaining solution of the Femtocell variable service users, and finally the optimization theory is adopted to solve the optimization problem to obtain power distribution optimization vectors of the FBS.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for fair control of service resources in a heterogeneous network fusion system. Background technique [0002] In the research of key technologies in the heterogeneous network convergence scenario, how to realize high-throughput wireless communication at low cost and high efficiency is one of the key points, and the use of wireless resource sharing and allocation technology can rationally optimize limited network resources . [0003] In a heterogeneous network scenario, a large number of femtocells (Femtocells) are deployed in macrocell (Macrocell) cells, so they form a heterogeneous network architecture with macrocells. Due to the relative scarcity of wireless spectrum resources, the spectrum resource architecture of Femtocell and macrocell in the same frequency band has been more and more recognized by people. However, the ensuing cross-layer co...

Problems solved by technology

Using the same resource allocation scheme for different services cannot dynamically and adaptively allocate resources according to service characteristics and user needs, resulting in waste of resources in the Femtocell network

[0006] Most of the existing heterogeneous network power control methods are based on the centralized or distributed power control methods of heterogeneous network base stations, and optimize the power allocation of Femtocell network base stations in order to solve the problem of maximizing network resource utilization under different network architectures.
