THE DISTRIBUTION OF SLICE SERVICE RESOURCES IN 5G NETWORKS

Abstract

The trend of mobile networks 5G is growing with the increase in the
number of users and the speed of transmission. Many operators are turning to small
cellular and internal coverage of telecommunication network services.Limited in
resources and space, the micro operator has the character of service regionalization,
enabling it to provide, in conditions where hardware infrastructure is scarce and
resources are limited, different regional services according to different domains.
Which makes it possible for mobile users to access services in the surrounding areas.
Due to the emergence of software-specific network technologies and virtualization of
network functions, the ISP can deploy its networks more flexibly and dynamically. In
addition to changing the model for deploying a wireless mobile network, it also
determines the tendency for micro-operators to develop (μO). Communication
operators can provide regional network services through public buildings, shopping
malls or industrial facilities. In addition, localized network services are provided and
bandwidth consumption is reduced. The distributed μO architecture meets the
computing requirements for applications, data, and services from the cloud data
center to the peripheral network devices or the micro-data center μO. The μO service
model is able to reduce network latency in response to applications with a low latency
for the future 5G boundary computing environment. This article discusses the design
of the micro-operator 5G and proposes a mechanism for redirecting flows based on
the decision tree (DTBFR) to redirect traffic flows to neighboring service nodes. The
DTBFR mechanism allows different microcontrollers to share network resources and
accelerate the development of border computing in the future.
