Sisitemu yo kuburira abaturage ya 5G (Radiyo Nshya) n'imiterere yayo

Sisitemu yo kuburira abaturage ya 5G (NR, cyangwa New Radio) (PWS) ikoresha ikoranabuhanga rigezweho n'ubushobozi bwo kohereza amakuru ku buryo bwihuse bw'imiyoboro ya 5G kugira ngo itange amakuru nyayo kandi y'ukuri ku baturage ku gihe. Iyi sisitemu igira uruhare runini mu gutanga amakuru mu gihe cy'ibiza (nk'imitingito na tsunami) n'impanuka z'umutekano w'abaturage, igamije kugabanya igihombo mu ibiza no kurengera ubuzima bw'abantu.

Incamake ya Sisitemu
Sisitemu yo kuburira abaturage (PWS) ni uburyo bw'itumanaho bukorwa n'inzego za leta cyangwa imiryango bireba kugira ngo bwohereze ubutumwa bw'ububurira abaturage mu gihe cy'impanuka. Ubu butumwa bushobora gukwirakwizwa binyuze mu nzira zitandukanye, harimo radiyo, televiziyo, ubutumwa bugufi, imbuga nkoranyambaga, n'imiyoboro ya 5G. Umuyoboro wa 5G, ufite igihe gito cyo gutinda, icyizere cyo hejuru, n'ubushobozi bunini, warushijeho kuba ingenzi muri PWS.

Uburyo bwo gutangaza ubutumwa muri 5G PWS
Mu miyoboro ya 5G, ubutumwa bwa PWS bunyuzwa kuri sitasiyo za NR zihujwe na 5G Core Network (5GC). Sitasiyo za NR zishinzwe gutegura no gutangaza ubutumwa bw'ububurira, no gukoresha uburyo bwo kumenyesha ibikoresho by'ububurira (UE) ko ubutumwa bw'ububurira burimo gutangizwa. Ibi bituma amakuru y'ububurira akwirakwizwa vuba kandi amakuru y'ubutabazi akwirakwizwa ku buryo burambuye.

Ibyiciro by'ingenzi bya PWS muri 5G

Sisitemu yo kuburira abantu ku mutingito na Tsunami (ETWS):
Byakozwe kugira ngo bihuze n'ibisabwa ku imenyesha ry'umuburo rijyanye n'impanuka z'umutingito cyangwa tsunami. Ubuhanuzi bwa ETWS bushobora gushyirwa mu byiciro nk'amatangazo y'ibanze (amatangazo magufi) n'amatangazo y'inyongera (gutanga amakuru arambuye), gutanga amakuru arambuye ku gihe kandi yuzuye ku baturage mu gihe cy'impanuka.
Sisitemu yo gutanga amakuru ku bijyanye n'ubucuruzi kuri telefoni zigendanwa (CMAS):
Sisitemu yo gutanga amakuru yihutirwa ku baturage itanga amakuru yihutirwa ku bakoresha binyuze mu miyoboro ya telefoni zigendanwa z'ubucuruzi. Muri imiyoboro ya 5G, CMAS ikora kimwe na ETWS ariko ishobora gutanga amakuru menshi ku bwoko bw'impanuka, nk'ikirere kibi n'ibitero by'iterabwoba.

Ibintu by'ingenzi bya PWS
Uburyo bwo gutanga amakuru kuri ETWS na CMAS:
ETWS na CMAS byombi bigena uburyo butandukanye bwo gutanga amakuru ku buryo bwa System Information Blocks (SIBs) kugira ngo bijyane ubutumwa bw'umuburo. Imikorere ya paging ikoreshwa mu kumenyesha UE ibimenyetso bya ETWS na CMAS. UE muri leta za RRC_IDLE na RRC_INACTIVE zikurikirana ibimenyetso bya ETWS/CMAS mu gihe cyo gukora paging, mu gihe muri RRC_CONNECTED, nazo zikurikirana ubwo butumwa mu gihe cyo gukora paging. ETWS/CMAS notification paging ituma amakuru ya system aboneka nta gutinda kugeza igihe cyo guhindura gitaha, bityo amakuru yihutirwa agakwirakwizwa ako kanya.

Inyongera za ePWS:
Sisitemu yo kumenyesha abantu bose (ePWS) yemerera gusakaza ibikubiye mu rurimi n'amatangazo kuri UE nta miyoboro cyangwa ngo ishobore kwerekana inyandiko. Iyi mikorere igerwaho binyuze muri gahunda n'amahame byihariye (urugero, TS 22.268 na TS 23.041), bituma amakuru yihutirwa agera ku bakoresha benshi.

KPAS na EU-Alert:
KPAS na EU-Alert ni izindi sisitemu ebyiri z’inyongera zo kuburira rubanda zagenewe kohereza amatangazo menshi y’ububurira icyarimwe. Zikoresha uburyo bumwe bwa Access Stratum (AS) nk’ubwa CMAS, kandi inzira za NR zigenwa kuri CMAS zikoreshwa kimwe kuri KPAS na EU-Alert, bigatuma habaho imikoranire no guhuza sisitemu.

Mu gusoza, Sisitemu yo kuburira abaturage ya 5G, hamwe n'imikorere yayo, uburyo bwizewe, kandi ikaba ikora neza, itanga ubufasha bukomeye ku baturage mu gihe cy'ubutabazi bwihutirwa. Uko ikoranabuhanga rya 5G rikomeza gutera imbere no kunoza, PWS izagira uruhare runini mu guhangana n'ibiza n'impanuka z'umutekano rusange.

Igitekerezo gitanga ubwoko bwose bw'ibice bya microwave bidakoreshejwe kuri sisitemu yo kuburira rubanda ya 5G (NR, cyangwa New Radio): Imashini igabanya ingufu, ihuza icyerekezo, iyungurura, iyungurura, hamwe n'ibice bya LOW PIM kugeza kuri 50GHz, hamwe n'ubwiza bwiza n'ibiciro bishimishije.
