Our High-Performing Core Network
Fully virtualizable on VMware, K8S, Docker and OpenStack containers
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.

FAQ
What is the role of the NSSF in a 5G Core network?
The Network Slice Selection Function (NSSF) is responsible for selecting the appropriate network slice instance for a user based on subscription data, service requirements, and network policies.
How does NSSF enable network slicing in 5G?
NSSF maps user requests to specific network slice instances (NSIs) and slice service types (SSTs), ensuring that each user or service is routed to the correct logical network with appropriate resources and performance.
How does NSSF interact with other 5G Core network functions?
NSSF works closely with network functions such as AMF and UDM. It provides slice selection assistance to AMF and uses subscription data from UDM to determine eligible slices for a user.
What information does NSSF use to select a network slice?
- NSSF considers:
- Subscriber slice subscription data
- Requested service type (SST/SD)
- Network policies and availability
- Roaming and access conditions
Can NSSF support multi-slice and multi-service scenarios?
Yes. NSSF supports multiple slice selection for different services, enabling operators to deliver differentiated QoS and service isolation for various use cases such as eMBB, URLLC, and mMTC.
How does NSSF support roaming scenarios?
In roaming scenarios, NSSF helps determine whether to use home-routed or visited network slices and ensures proper slice selection across different operator networks.
What deployment models are supported for NSSF?
NSSF can be deployed in centralized or distributed architectures and supports cloud-native environments for flexible scaling and high availability.
How does NSSF ensure scalability in large 5G networks?
NSSF is designed to handle large volumes of slice selection requests and can scale horizontally to support massive device connections and diverse service requirements.
