5GC, 5G Core Network Solution ∣ IPLOOK

5G Core Network(5GC)

5G Core Network(5GC) holds a key role in realizing the full potential of 5G services. Without 5GC, fully-fledged NR services cannot be obtained. 5G NSA deployment leaning on traditional LTE network and EPC allows for a quick launch of 5G services, but also hinders the realization of 5G' s full potential.

Base on Service Based Architecture(SBA), in 5GC, a cloud native design is introduced to enable flexible scaling and upgrades.

IPLOOK's Ultra 5G Core Network
IPLOOK's 5GC includes the elements: UPF, AUSF, UDM, AMF, SMF, PCF, NSSF, NRF, NEF
Highly compact, IPLOOK 5GC can be implemented on low end COTS servers, or can utilize available CPU capacity in a radio by embedding directly into available CPU cores within the radio itself. It can also be containerized for deployment on an NFV platform.
IPLOOK 5GC has higher compatibility and will be upgraded to support 3G and 4G user access. Users can register for 3G/4G/ 5G networks, thus ensuring a smooth upgrade to 5G for existing 3G/4G users.
We enable 5G services for Service Providers, Systems Integrators, Enterprises and Government Organizations while optimally leveraging investments of existing networks and systems, at price levels which are significantly lower than the products of the established tier 1 vendors.

User Plane Function(UPF)
User Plane Function(UPF)
The User Plane Function (UPF) represents the data plane evolution of a Control and User Plane Separation (CUPS) strategy, which is a fundamental component of the 3GPP 5G core network(5GC).

The UPF plays the most critical role in the process of data transfer. It provides the interconnect point between the mobile infrastructure and the Data Network (DN), i.e. encapsulation and decapsulation of GTP-U.

Network Exposure Function(NEF)
Network Exposure Function(NEF)
NEF, located between the 5G core network and external third-party application functionaries (and possibly some internal AFs), is responsible for managing the external open network data, and all external applications that want to access the internal data of the 5G core must pass through the NEF.

By opening the network capability to third-party applications, it can realize the friendly connection between network capability and business requirements, improve business experience and optimize network resource allocation.

Network Repository Function(NRF)
Network Repository Function(NRF)
NRF, one of the network functions of the 5G core network(5GC). It supports the service discovery feature, which receives NF discovery requests from NF instances and provides information about the discovered NF instance (discovered) to another NF instance. Registration information includes NF type, address, service list, etc.

Network Slice Selection Function(NSSF)
Network Slice Selection Function(NSSF)
Network slicing is a key native capability of 5G that can maximize the performance of communication networks and reduce network construction and operation and maintenance costs, and it has become an industry consensus that 'slicing is capability and slicing is product' in the 5G era.
The core network, as a key anchor point for network differentiation and operation, has emerged as a more important network in the 5G era, providing the ability to deploy network functions and resources on-demand to meet the diverse business needs of future vertical industries.
