5g Core Network Architecture 3gpp

Security aspects of service enabler architecture layer seal for verticals.

5g core network architecture 3gpp. 3gpp system architecture evolution sae. 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. Reference point system architecture. A distinct key feature of the 5g system architecture is network slicing.

Minimize dependencies between the access network an and the core network cn. It needs to deliver a seamless service experience across fixed and wireless access technologies. Etsi ts 123 501 v15 2 0 2018 06 5g. 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.

System architecture for the 5g system 3gpp ts 23 501 version 15 2 0 release 15 technical specification. 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. Compared to this 5g network slicing is a more powerful concept and includes the whole plmn.

Within the scope of the 3gpp 5g system architecture a network slice. The architecture is defined with a converged core network with a common an cn interface which integrates different access 5g core architecture models. 3gpp has defined a new 5g core architecture that supports service delivery over wireless fixed or converged networks. 3gpp specified and presents both versions of 5g system architectures.

For a successful 5g launch the operator needs to secure a network that includes end to end e2e capabilities aligned across devices ran core and management systems. Security aspects of non 3gpp accesses. The 5g core will be the heart of the network and acts as an anchor point for multi access technologies. The 5g core network architecture is at the heart of the new 5g specification and enables the increased throughput demand that 5g must support.

The previous generation supported certain aspects of this with the functionality for dedicated core networks. The relevant basics of ng ran are also covered. This course presents the 5g system 5gs as defined by 3gpp focusing on the functionalities of the 5g core 5gc network.
