Nyob rau hauv 2015, lub thoob ntiaj teb kev sib txuas lus union (ITU) tso tawm IMT lub zeem muag: 5G architecture thiab tag nrho cov hom phiaj, uas txhais tau peb daim ntawv thov scenarios ntawm enhanced mobile broadband (eMBB), ultra-siab kev ntseeg siab thiab tsawg latency (uRLLC), loj tshuab hom kev sib txuas lus (mMTC. ), thiab yim qhov tseem ceeb ntawm kev ua tau zoo xws li tus nqi siab tshaj thiabtsheb ceev.
Piv nrog rau 4G, 5G yuav muab tsawg kawg kaum npaug ntawm qhov siab tshaj plaws ntawm 4G, millisecond kis tau tus mob qeeb thiab ntau lab ntawm kev sib txuas ib square km.
Los ntawm qhov kev xav ntawm network architecture, 5G network txuas ntxiv tag nrho cov yam ntxwv 4G, suav nrog kev nkag mus rau network, core network thiab daim ntawv thov txheej sab saud (raws li qhia hauv daim duab hauv qab no). Txhawm rau ua kom tau raws li qhov xav tau ntawm kev lag luam sib txawv ntawm 5G mobile Internet thiab mobile iot, 5G network tau txais cov thev naus laus zis tshiab hauv ob qho tib si hauv lub network thiab nkag mus rau network, paub txog kev tsim kho tshiab thiab kev hloov kho network.
Los ntawm kev xav ntawm thev naus laus zis, cov thev naus laus zis tseem ceeb tau txais los ntawm 5G yog:
Servitization architecture: nyob rau hauv 5G servitization architecture, network functions yog muab raws li cov kev pab cuam rau lub ntiaj teb no sab nrauv, thiab sib txawv network functions thiab cov kev pab cuam yog intercommunicated los ntawm tus txheej txheem interfaces, txhawb on-demand invocation thiab functional reconstruction, thiaj li los txhim kho qhov yooj thiab qhib. tuscore network. 5G servitization architecture yog ib qho tseem ceeb txhais tau tias kom tau raws li qhov xav tau ntawm kev lag luam ntsug hauv 5G era.
Network muaj nuj nqi virtualization: lub tshuab virtualization tau txais los txiav txim siab kho vajtse thiab software ntawm cov khoom ntiag tug ntawm lub network ib txwm muaj, tsim lub network ua haujlwm raws li kev sib koom ua ke virtual, paub txog kev tswj hwm hauv nruab nrab, kev teeb tsa zoo, sijhawm teem sijhawm thiab ntse xa mus. cov kev pab cuam, thiab shorten lub lag luam innovation voj voog ntawm kev ua hauj lwm network.
Network slicing: network slicing tuaj yeem txiav ntau qhov kev sib txuas lus nrog cov haujlwm sib txawv thiab cov yam ntxwv ntawm lub cev lub cev, thiab txhawb ntau yam kev lag luam nyob rau tib lub sijhawm. Raws li kev siv tshuab slicing network, kev siv cov peev txheej hauv network tuaj yeem txhim kho thiab cov peev txheej hauv network xav tau los ntawm cov xwm txheej lag luam sib txawv tuaj yeem raug cais tawm.
Edge xam: ntug kev xam yog nyob ntawm ntug ntawm lub network, nyob ze rau tus neeg siv, muab kev suav thiab cov ntaub ntawv ua lub peev xwm, txhawm rau txhim kho lub network cov ntaub ntawv kev ua haujlwm zoo, kom tau raws li kev lag luam ntsug network qeeb qeeb, tsheb loj thiab kev ruaj ntseg. .
Network peev xwmqhib: 5G network tuaj yeem qhib lub peev xwm network rau cov ntawv thov thib peb los ntawm kev muaj peev xwm qhib interface, kom cov neeg thib peb tuaj yeem tsim cov kev pabcuam network raws li lawv tus kheej xav tau.
Cov thev naus laus zis tseem ceeb ntawm kev nkag mus rau hauv lub network: 5G tau txais kev tsim qauv tsim los txhawb ntau yam kev pabcuam thiab cov xwm txheej hauv kev nkag mus rau hauv lub network, thiab siv cov txheej txheem tshiab channel coding thiab cov kav hlau txais xov loj loj los txhawb kev sib kis tau zoo thiab kev pabcuam zoo dua.
