Simplified Network

Building efficient, intelligent, and open 5G Cloud & Network

Resource Control Center for the Network Service and Slicing

ZXUN NSR (Network Function Service Repository) realizes the functions of NRF (NF Repository Function), NSSF (Network Slice Selection Function) and Gn-DNS in the 3GPP architecture. It supports NRF functions such as NF management, NF discovery and NF OAuth to help 5GC NFs & services realize plug and play. It supports NSSF functions such as network slice selection, NSSAI availability to help end users realize slice-level user experience. It supports multiple DNS query types such as A, AAAA, SRV, NAPTR and S-NAPTR and multiple DNS query modes such as recursive query and iterative query to meet the domain name parse requirements of NEs.
