The 5G (New Radio) Public Warning System ndi Makhalidwe Ake

The 5G (NR, kapena New Radio) Public Warning System (PWS) imagwiritsa ntchito matekinoloje apamwamba komanso mphamvu zotumizira mauthenga othamanga kwambiri pamanetiweki a 5G kuti apereke chidziwitso chadzidzidzi chanthawi yake komanso cholondola kwa anthu. Dongosololi limagwira ntchito yofunika kwambiri pakufalitsa zidziwitso pakagwa masoka achilengedwe (monga zivomezi ndi tsunami) komanso zochitika zachitetezo cha anthu, pofuna kuchepetsa kutayika kwa masoka ndikuteteza miyoyo ya anthu.

System Overview
Public Warning System (PWS) ndi njira yolankhulirana yoyendetsedwa ndi mabungwe aboma kapena mabungwe ofunikira kuti atumize machenjezo kwa anthu panthawi yadzidzidzi. Mauthengawa amatha kufalitsidwa kudzera munjira zosiyanasiyana, kuphatikiza wailesi, wailesi yakanema, ma SMS, ma social media, ndi ma network a 5G. Maukonde a 5G, omwe ali ndi latency yochepa, yodalirika kwambiri, ndi mphamvu zazikulu, zakhala zofunikira kwambiri mu PWS.

Message Broadcasting Mechanism mu 5G PWS
Mumanetiweki a 5G, mauthenga a PWS amafalitsidwa kudzera m'malo oyambira a NR olumikizidwa ndi 5G Core Network (5GC). Masiteshoni a NR ali ndi udindo wokonza ndi kuwulutsa mauthenga ochenjeza, ndikugwiritsa ntchito ma paging kuti adziwitse Zida Zogwiritsa (UE) kuti mauthenga ochenjeza akufalitsidwa. Izi zimatsimikizira kufalitsa mwachangu komanso kufalitsa zambiri zadzidzidzi.

Magulu Akuluakulu a PWS mu 5G

Chenjezo la Chivomezi ndi Tsunami (ETWS):
Zapangidwa kuti zikwaniritse zofunikira za zidziwitso zokhudzana ndi chivomezi ndi/kapena zochitika za tsunami. Machenjezo a ETWS atha kugawidwa ngati zidziwitso zoyambira (zidziwitso zazifupi) ndi zidziwitso zachiwiri (zopereka zambiri), zomwe zimapereka chidziwitso chapanthawi yake komanso chokwanira kwa anthu panthawi yadzidzidzi.
Dongosolo Lazidziwitso Zam'manja Zamalonda (CMAS):
Dongosolo lodziwitsa anthu zadzidzidzi lomwe limapereka zidziwitso zadzidzidzi kwa ogwiritsa ntchito kudzera pamanetiweki am'manja amalonda. Mumanetiweki a 5G, CMAS imagwira ntchito mofanana ndi ETWS koma imatha kuphimba mitundu yambiri ya zochitika zadzidzidzi, monga nyengo yoopsa komanso zigawenga.

Zithunzi za PWS
Njira Zodziwitsa za ETWS ndi CMAS:
Onse a ETWS ndi CMAS amatanthauzira ma System Information Blocks (SIBs) osiyanasiyana kuti azinyamula mauthenga ochenjeza. Kugwiritsa ntchito tsamba kumagwiritsidwa ntchito kudziwitsa ma UE za ETWS ndi CMAS zowonetsa. Ma UEs ku RRC_IDLE ndi RRC_INACTIVE madera amayang'anira ma ETWS/CMAS akamalemba matsamba, pomwe ali m'chigawo cha RRC_CONNECTED, amawunikanso mauthengawa pamasamba ena. ETWS/CMAS notification pageging imayambitsa kupezeka kwa zidziwitso zamakina popanda kuchedwetsa mpaka nthawi yosintha, kuwonetsetsa kufalitsidwa mwachangu kwa chidziwitso chadzidzidzi.

Zowonjezera ePWS:
The Public Warning System (ePWS) yowongoleredwa imalola kuti zidziwitso ndi zidziwitso zigwirizane ndi chilankhulo ku ma UE popanda mawonekedwe kapena osatha kuwonetsa mawu. Izi zimatheka kudzera mu ndondomeko ndi mfundo zina (monga TS 22.268 ndi TS 23.041), kuwonetsetsa kuti zambiri zadzidzidzi zifika kwa anthu ambiri.

KPAS ndi EU-Alert:
KPAS ndi EU-Alert ndi njira ziwiri zowonjezera zochenjeza anthu zomwe zimapangidwa kuti zitumize zidziwitso zochenjeza nthawi imodzi. Amagwiritsa ntchito njira zomwezo za Access Stratum (AS) monga CMAS, ndipo njira za NR zofotokozedwa za CMAS zimagwiranso ntchito ku KPAS ndi EU-Alert, zomwe zimathandizira kuti zitheke kugwirira ntchito limodzi ndi kugwilizana pakati pa machitidwe.

Pomaliza, 5G Public Warning System, ndikuchita bwino kwake, kudalirika, komanso kufalikira kwakukulu, imapereka chithandizo champhamvu chadzidzidzi kwa anthu. Pomwe ukadaulo wa 5G ukupitilirabe kusintha ndikusintha, PWS itenga gawo lofunikira kwambiri pakuyankha masoka achilengedwe komanso zochitika zachitetezo cha anthu.

Lingaliro limapereka zigawo zonse za ma microwave amtundu uliwonse wa The 5G (NR, kapena New Radio) Public Warning Systems : Power divider, directional coupler, fyuluta, duplexer, komanso zigawo za LOW PIM mpaka 50GHz, zokhala ndi khalidwe labwino komanso mitengo yampikisano.
