Core network control plane elastic resource allocation method in NFV environment

Abstract

The invention belongs to the technical field of mobile communication, and particularly relates to a core network control plane elastic resource allocation method in an NFV environment. The method provided by the invention specifically comprises the following steps: step 1, establishing a core network control plane performance evaluation model by adopting an open queuing network; 2, constructing aperformance-aware core network control plane resource allocation multi-objective optimization model; and 3, proposing an improved multi-target genetic algorithm, and solving a core network control surface multi-target resource allocation problem. The problems that in the prior art, core network control plane performance evaluation precision is not high, and processing performance and resource costare not comprehensively considered in resource allocation are solved. The method provided by the invention can solve the problems that the core network control plane performance evaluation precisionis not high and the processing performance and the resource cost are not comprehensively considered in resource allocation in the prior art.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method for allocating elastic resources of a core network control plane in an NFV environment. Background technique [0002] The core network is an important part of the mobile communication network. In the traditional Evolved Packet Core (EPC) architecture, network elements of the core network are implemented as dedicated hardware devices, the flexibility and scalability of the core network are poor, and the deployment cost is high. With the advent of the 5G era, in order to cope with challenges such as explosive data traffic growth and massive device access, mobile operators must change the traditional EPC network architecture. Network Function Virtualization (Network Function Virtualization, NFV) is a new network paradigm, which has changed the traditional way of implementing network functions. Based on NFV technology, the network elements of the c...
