Slice architecture for 5g 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. The 5g core will be the heart of the network and acts as an anchor point for multi access technologies. 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. It needs to deliver a seamless service experience across fixed and wireless access technologies.

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. 5g network slicing is a network architecture that enables the multiplexing of virtualized and independent logical networks on the same physical network infrastructure. Each network slice is an isolated end to end network tailored to fulfil diverse requirements requested by a particular application. 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.

Compute storage and networking resources an information model fragment for network slice and nss is defined in the 5g nrm. Each slice is used for different tasks to. 3gpp has defined a new 5g core architecture that supports service delivery over wireless fixed or converged networks. 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.

This new 5g core uses a. Docomo designed the network slice creation and selection functions while ericsson developed the network slice lifecycle and service management technologies. 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. In 5g network management is envisioned to be software driven and network functions resources are virtualized at the edges and core.
