- UDR - Pupuri Raraunga Whakakotahi.
- UPF - Mahinga Mahinga Kaiwhakamahi.
I roto i nga huringa o te putanga 3.4.0:
- Ko te whakatinanatanga o te SBA (Service-Based Architecture) kua taapirihia he tautoko mo te kawa whakamanatanga OAuth, ka taea te whakamahi i roto i nga ratonga katoa (AMF, SMF, NRF, PCF, UDR, UDM, AUSF, NSSF) ki te whakamana me te tono tohu uru. . Kua taapirihia e te waahanga NRF (Network Repository Function) te kaha ki te mahi hei tūmau whakamana.
- He tautoko taapiri mo te Rehitatanga marama. Hei tauira, ka tukuna pea e te taputapu pūkoro a te kaiwhakamahi (UE) kua rehitatia me te AMF tawhito (Access Management Function) he tono rehitatanga ki tetahi AMF hou, ka tono pea tenei AMF hou ki te AMF tawhito kia mutu te rehitatanga.
- He tautoko taapiri mo nga tono ki te whakarereke i te ararere (“NAS Reroute”).
- Kua taapirihia e te whakahau Whakahou Whirihoranga UE te tautoko mo te tikanga NITZ (Waitunga Whatunga me te Rohe Wa) ki te whakawhiti i nga korero wa me te rohe waahi ki te taputapu a te kaiwhakamahi.
Ko etahi atu whakatinanatanga o nga hangarau mo te tuku whatunga waea pūkoro 5G ko nga kaupapa NextEPC, OpenAir, Magma, Open5GS, Open5GCore, OAI-CN me srsRAN.
