I-5G (Irediyo Entsha) Uhlelo Lwesexwayiso Lomphakathi Nezimpawu Zalo

I-5G (NR, noma i-New Radio) Public Warning System (PWS) isebenzisa ubuchwepheshe obuthuthukisiwe namandla okudlulisa idatha ngesivinini esikhulu samanethiwekhi e-5G ukuze inikeze ulwazi olufika ngesikhathi nolunembile lwesixwayiso esiphuthumayo emphakathini. Lolu hlelo ludlala indima ebalulekile ekusabalaliseni izexwayiso ngesikhathi sezinhlekelele zemvelo (njengokuzamazama komhlaba nama-tsunami) kanye nezehlakalo zokuphepha komphakathi, okuhloswe ngazo ukunciphisa ukulahleka kwezinhlekelele nokuvikela izimpilo zabantu.

Ukubuka konke Kwesistimu
I-Public Warning System (PWS) iwuhlelo lokuxhumana olusetshenziswa ama-ejensi kahulumeni noma izinhlangano ezifanele ukuthumela imilayezo yesixwayiso emphakathini ngesikhathi sezimo eziphuthumayo. Le miyalezo ingasatshalaliswa ngeziteshi ezahlukahlukene, okuhlanganisa umsakazo, umabonakude, i-SMS, izinkundla zokuxhumana, kanye namanethiwekhi e-5G. Inethiwekhi ye-5G, ene-latency ephansi, ukuthembeka okuphezulu, nomthamo omkhulu, isiye yabaluleka kakhulu ku-PWS.

I-Message Broadcasting Mechanism ku-5G PWS
Kumanethiwekhi e-5G, imilayezo ye-PWS isakazwa ngeziteshi eziyisisekelo ze-NR ezixhunywe ku-5G Core Network (5GC). Iziteshi eziyisisekelo ze-NR zinomthwalo wemfanelo wokuhlela nokusakaza imilayezo yesixwayiso, nokusebenzisa ukusebenza kwekhasi ukwazisa Isisetshenziswa Somsebenzisi (UE) ukuthi imilayezo eyisixwayiso iyasakazwa. Lokhu kuqinisekisa ukusatshalaliswa okusheshayo kanye nokufakwa okubanzi kolwazi oluphuthumayo.

Izigaba Eziyinhloko ze-PWS ku-5G

Uhlelo Lwesexwayiso Ngokuzamazama komhlaba kanye ne-Tsunami (ETWS):
Idizayinelwe ukuhlangabezana nezimfuneko zesaziso esihlobene nokuzamazama komhlaba kanye/noma izehlakalo ze-tsunami. Izexwayiso ze-ETWS zingahlukaniswa njengezaziso eziyinhloko (izaziso ezimfushane) kanye nezaziso zesibili (ezinikeza imininingwane enemininingwane), zinikeze ulwazi olufika ngesikhathi noluphelele emphakathini ngesikhathi sezimo eziphuthumayo.
Uhlelo Lokwazisa Ngeselula Yezentengiso (CMAS):
Uhlelo lokwazisa oluphuthumayo olusesidlangalaleni oluletha izexwayiso zesimo esiphuthumayo kubasebenzisi ngamanethiwekhi eselula ezentengiso. Kumanethiwekhi e-5G, i-CMAS isebenza ngendlela efanayo ne-ETWS kodwa ingase ihlanganise uhla olubanzi lwezinhlobo zezenzakalo eziphuthumayo, njengesimo sezulu esibi nokuhlasela kwamaphekula.

Izici ezibalulekile ze-PWS
Indlela Yokwazisa Ye-ETWS ne-CMAS:
Kokubili i-ETWS ne-CMAS ichaza ama-System Information Blocks (SIBs) ahlukene ukuze aphathe imilayezo eyisixwayiso. Ukusebenza kwekhasi kusetshenziselwa ukwazisa ama-UE mayelana nezinkomba ze-ETWS ne-CMAS. Ama-UE asezifundazweni ezingu-RRC_IDLE nase-RRC_INACTIVE aqapha izinkomba ze-ETWS/CMAS phakathi nezikhathi zokuphega, kuyilapho kusimo se-RRC_CONNECTED, aphinde agade le milayezo ngezinye izikhathi zokupheja. Ukuphegiswa kwesaziso se-ETWS/CMAS kubangela ukutholwa kolwazi lwesistimu ngaphandle kokulibazisa kuze kube yisikhathi esilandelayo sokulungiswa, okuqinisekisa ukusatshalaliswa ngokushesha kolwazi oluphuthumayo.

Izithuthukisi ze-ePWS:
Uhlelo Lwesexwayiso Lomphakathi oluthuthukisiwe (i-ePWS) luvumela ukusakaza okuqukethwe okuncike olimini kanye nezaziso kuma-UEs ngaphandle kokusetshenziswa kubonwa noma ukungakwazi ukubonisa umbhalo. Lokhu kusebenza kufinyelelwa ngamaphrothokholi namazinga athile (isb, i-TS 22.268 ne-TS 23.041), ukuqinisekisa ukuthi ulwazi oluphuthumayo lufinyelela kusisekelo sabasebenzisi esibanzi.

I-KPAS ne-EU-Alert:
I-KPAS kanye ne-EU-Alert amasistimu amabili angeziwe esexwayiso asesidlangalaleni aklanyelwe ukuthumela izaziso eziningi zesixwayiso ngesikhathi esisodwa. Basebenzisa izindlela ezifanayo ze-Access Stratum (AS) njenge-CMAS, futhi izinqubo ze-NR ezichazwe ku-CMAS zisebenza ngokulinganayo ku-KPAS ne-EU-Alert, okuvumela ukusebenzisana nokuhambisana phakathi kwamasistimu.

Sengiphetha, Uhlelo Lwezixwayiso Lomphakathi lwe-5G, nokusebenza kahle kwalo, ukwethembeka, nokufaka kabanzi, luhlinzeka ngosekelo oluqinile lwesixwayiso esiphuthumayo emphakathini. Njengoba ubuchwepheshe be-5G buqhubeka nokuthuthuka futhi buthuthuka, i-PWS izodlala indima ebaluleke nakakhulu ekuphenduleni izinhlekelele zemvelo kanye nezigameko zokuphepha komphakathi.

I-Concept inikeza uhla olugcwele lwezingxenye ze-microwave ezingenzi lutho ze-The 5G (NR, noma I-New Radio) Yezixwayiso Zomphakathi : Isihlukanisi Samandla Amandla , i-directional coupler , isihlungi , i-duplexer , kanye nezingxenye ze-PIM EZINGAPHANSI ezifika ku-50GHz, ezinekhwalithi enhle nezintengo ezincintisanayo.
