Uhlelo Lokuxwayisa Umphakathi lwe-5G (NR, noma i-New Radio) (PWS) lusebenzisa ubuchwepheshe obuthuthukisiwe kanye namakhono okudlulisa idatha ngesivinini esikhulu samanethiwekhi e-5G ukuze lunikeze ulwazi oluphuthumayo olufika ngesikhathi nolunembile emphakathini. Lolu hlelo ludlala indima ebalulekile ekusakazeni izexwayiso ngesikhathi sezinhlekelele zemvelo (njengokuzamazama komhlaba nama-tsunami) kanye nezehlakalo zokuphepha komphakathi, luhlose ukunciphisa ukulahlekelwa yizinhlekelele nokuvikela izimpilo zabantu.
Ukubuka Konke Kwesistimu
Uhlelo Lokuxwayisa Umphakathi (i-PWS) luhlelo lokuxhumana oluqhutshwa yizikhungo zikahulumeni noma izinhlangano ezifanele ukuthumela imiyalezo yokuxwayisa emphakathini ngesikhathi sezimo eziphuthumayo. Le miyalezo ingasatshalaliswa ngeziteshi ezahlukene, okuhlanganisa umsakazo, ithelevishini, i-SMS, izinkundla zokuxhumana, kanye namanethiwekhi e-5G. Inethiwekhi ye-5G, ngokubambezeleka kwayo okuphansi, ukuthembeka okuphezulu, kanye nomthamo omkhulu, isibe yinto ebaluleke kakhulu ku-PWS.
Indlela Yokusakaza Imiyalezo ku-5G PWS
Kumanethiwekhi e-5G, imiyalezo ye-PWS isakazwa ngeziteshi zesisekelo ze-NR ezixhunywe ku-5G Core Network (5GC). Iziteshi zesisekelo ze-NR zinomthwalo wokuhlela nokusakaza imiyalezo yesixwayiso, kanye nokusebenzisa ukusebenza kwe-paging ukwazisa Imishini Yomsebenzisi (UE) ukuthi imiyalezo yesixwayiso iyasakazwa. Lokhu kuqinisekisa ukusatshalaliswa okusheshayo kanye nokumbozwa kabanzi kolwazi oluphuthumayo.
Izigaba Eziyinhloko ze-PWS ku-5G
Uhlelo Lokuxwayisa Ngokuzamazama Komhlaba kanye Ne-Tsunami (ETWS):
Yakhelwe ukuhlangabezana nezidingo zesaziso sesixwayiso ezihlobene nokuzamazama komhlaba kanye/noma izehlakalo ze-tsunami. Izexwayiso ze-ETWS zingahlukaniswa njengezaziso eziyinhloko (izexwayiso ezimfushane) kanye nezaziso zesibili (ezinikeza ulwazi oluningiliziwe), ezihlinzeka ngolwazi olufika ngesikhathi noluphelele emphakathini ngesikhathi sezimo eziphuthumayo.
Uhlelo Lwesaziso Seselula Yezentengiselwano (i-CMAS):
Uhlelo lwesaziso esiphuthumayo somphakathi olunikeza izaziso eziphuthumayo kubasebenzisi ngamanethiwekhi eselula ezentengiselwano. Kumanethiwekhi e-5G, i-CMAS isebenza ngendlela efanayo ne-ETWS kodwa ingahlanganisa izinhlobo eziningi zemicimbi ephuthumayo, njengesimo sezulu esibi kanye nokuhlasela kwamaphekula.
Izici Eziyinhloko ze-PWS
Indlela Yesaziso ye-ETWS ne-CMAS:
Kokubili i-ETWS ne-CMAS zichaza ama-System Information Blocks (SIBs) ahlukene ukuze athwale imiyalezo yesixwayiso. Ukusebenza kwe-paging kusetshenziselwa ukwazisa ama-UE mayelana nezinkomba ze-ETWS ne-CMAS. Ama-UE ezifundazweni ze-RRC_IDLE kanye ne-RRC_INACTIVE aqapha izinkomba ze-ETWS/CMAS ngesikhathi semicimbi yawo ye-paging, kuyilapho ezifundazweni ze-RRC_CONNECTED, nawo aqapha le milayezo ngesikhathi seminye imicimbi ye-paging. I-paging yesaziso se-ETWS/CMAS ibangela ukutholwa kolwazi lwesistimu ngaphandle kokulibazisa kuze kube yisikhathi esilandelayo sokuguqulwa, okuqinisekisa ukusatshalaliswa ngokushesha kolwazi oluphuthumayo.
Ukuthuthukiswa kwe-ePWS:
Uhlelo Lokuxwayisa Lomphakathi oluthuthukisiwe (i-ePWS) luvumela ukusakaza okuqukethwe okusekelwe olimini kanye nezaziso kuma-UE ngaphandle kokusetshenziswa komsebenzisi noma ukungakwazi ukubonisa umbhalo. Lokhu kusebenza kufezwa ngokusebenzisa amaphrothokholi athile kanye namazinga (isb., i-TS 22.268 kanye ne-TS 23.041), okuqinisekisa ukuthi ulwazi oluphuthumayo lufinyelela kubasebenzisi abaningi.
I-KPAS kanye ne-EU-Alert:
I-KPAS kanye ne-EU-Alert yizinhlelo ezimbili ezengeziwe zokuxwayisa umphakathi ezenzelwe ukuthumela izaziso eziningi zesexwayiso ngasikhathi sinye. Zisebenzisa izindlela ezifanayo ze-Access Stratum (AS) njenge-CMAS, futhi izinqubo ze-NR ezichazwe ku-CMAS zisebenza ngokulinganayo ku-KPAS kanye ne-EU-Alert, okuvumela ukusebenzisana kanye nokuhambisana phakathi kwezinhlelo.
Ekuphetheni, i-5G Public Wear System, kanye nokusebenza kwayo kahle, ukuthembeka, kanye nokusabalalisa kabanzi, inikeza ukwesekwa okuqinile kwezixwayiso eziphuthumayo emphakathini. Njengoba ubuchwepheshe be-5G buqhubeka nokukhula nokuthuthuka, i-PWS izodlala indima ebaluleke kakhulu ekuphenduleni izinhlekelele zemvelo kanye nezehlakalo zokuphepha komphakathi.
I-Concept inikeza uhla oluphelele lwezingxenye ze-microwave ezingasebenzi ze-5G (NR, noma i-New Radio) Public Werning Systems: I-Power Power divider, i-directional coupler, i-filter, i-duplexer, kanye nezingxenye ze-LOW PIM ezifika ku-50GHz, ngekhwalithi enhle namanani ancintisanayo.
