Cov NRF yog ib feem tseem ceeb ntawm cov 5g ua Service Based Architecture. Ntxiv rau kev ua haujlwm raws li qhov chaw khaws cia ntawm cov kev pabcuam, lub NRF kuj txhawb kev tshawb nrhiav mechanisms uas tso cai 5g ua cov ntsiab lus kom pom ib leeg thiab tau txais cov xwm txheej tshiab ntawm cov ntsiab lus xav tau.

Kuj paub, AMF yog dab tsi hauv 5g?

Nrog rau kev ua haujlwm ntawm 4G Mobility Management Entity (MME) tam sim no decomposed, lub 5g ua Core Access thiab Mobility Management Function ( AMF ) tau txais txhua qhov kev sib txuas thiab kev sib tham txog cov ntaub ntawv los ntawm Cov Khoom Siv (UE) (N1/N2) tab sis tsuas yog lub luag haujlwm rau kev tuav kev sib txuas thiab kev tswj xyuas cov haujlwm.

Ib yam li ntawd, 5g SMF yog dab tsi? Cov 5g ua Session Management Function ( SMF ) yog lub hauv paus ntsiab lus ntawm lub 5g ua Service-Based Architecture (SBA). Cov SMF Nws yog lub luag haujlwm tseem ceeb rau kev cuam tshuam nrog lub dav hlau decoupled cov ntaub ntawv, tsim kho thiab tshem tawm Cov Txheej Txheem Cov Ntaub Ntawv (PDU) ntu thiab tswj cov ntsiab lus sib tham nrog Tus Neeg Siv Dav Hlau Function (UPF).

Kuj tseem paub, UPF yog dab tsi hauv 5g?

Tus neeg siv dav hlau muaj nuj nqi ( UPF ) yog ib qho tseem ceeb ntawm 3GPP 5g ua core infrastructure system architecture. CUPS decouples Packet Gateway (PGW) tswj thiab cov neeg siv lub dav hlau ua haujlwm, ua kom cov ntaub ntawv xa mus (PGW-U) kom muaj kev faib tawm.

Dab tsi yog qhov kev sib tham PDU hauv 5g?

Hauv 5g ua , a PDU Session tuaj yeem teeb tsa nruab nrab ntawm lub davhlau ya nyob twg (tseem hu ua UE) thiab ntug ntawm tus neeg teb xov tooj lub network uas peb tam sim no pom Tus Neeg Siv Dav Hlau Function (UPF). PDU luv luv rau Packet Data Unit, thiab a PDU tuaj yeem yog IP pob ntawv. Zoo nkauj npaum li cov ntaub ntawv khiav hauv GPRS, UMTS thiab 4G.
