Slice Architecture For 5g Core Network

In this paper we define a flexible adaptable and programmable architecture for 5g mobile networks taking into consideration the requirements kpis and the current gaps in the literature based on three design fundamentals.

Slice architecture for 5g core network.

I split of user and control plane ii service based architecture within the core network in line with recent industry and standard consensus and iii. For this reason this technology assumes a central role to support 5g mobile networks that are. Each slice is used for different tasks to. 5g core 5gc network architecture implementation doesn t exactly follow the network evolution upgrade path as previously followed by 2g 3g and 4g networks and this is what makes 5g architecture very different from its predecessors.

Each network slice is an isolated end to end network tailored to fulfil diverse requirements requested by a particular application. In may 2017 the partners demonstrated the world s first 5g network slicing solution with multiple slices on the same device focused on using robots for building automation. Compute storage and networking resources an information model fragment for network slice and nss is defined in the 5g nrm. To support management and orchestration of network slice and network slice subnet nss which represents the management aspects of a set of managed functions and the required resources e g.

In 5g network management is envisioned to be software driven and network functions resources are virtualized at the edges and core. 1 2 the service driven 5g architecture end to end network slicing for multiple industries based on one physical infrastructure reconstructing the ran with cloud 3 1 multi connectivity is key to high speed and reliability 3 2 mce cloud native new core architecture 4 1 control and user plane separation simplifies the core network. The new 5g core as defined by 3gpp utilizes cloud aligned service based architecture sba that spans across all 5g functions and interactions including authentication security session management. This new 5g core uses a.

Explore ericsson s 5g core solution characteristics and benefits and hear what our customers have to say throughout this page. The 5g core will be the heart of the network and acts as an anchor point for multi access technologies. It needs to deliver a seamless service experience across fixed and wireless access technologies. Docomo designed the network slice creation and selection functions while ericsson developed the network slice lifecycle and service management technologies.

In short 5g core is a fundamental piece of the 5g network to enhance end user experience simplify operations add service agility and improve network capabilities all thanks to its future proof network architecture. 5g network slicing is a network architecture that enables the multiplexing of virtualised and independent logical networks on the same physical network.
