5G (NR, lossis Xov Tooj Cua Tshiab) Pej Xeem Ceeb Toom (PWS) siv cov thev naus laus zis siab thiab muaj peev xwm xa cov ntaub ntawv ceev ceev ntawm 5G tes hauj lwm los muab cov ntaub ntawv ceeb toom xwm txheej ceev thiab raug raws sijhawm rau pej xeem. Cov kab ke no ua lub luag haujlwm tseem ceeb hauv kev tshaj tawm cov lus ceeb toom thaum muaj kev puas tsuaj ntuj tsim (xws li av qeeg thiab tsunami) thiab xwm txheej kev nyab xeeb rau pej xeem, txhawm rau txo qis kev puas tsuaj thiab tiv thaiv tib neeg lub neej.
Txheej txheem cej luam
Public Warning System (PWS) yog ib qho kev sib txuas lus ua haujlwm los ntawm tsoomfwv cov koom haum lossis cov koom haum cuam tshuam los xa cov lus ceeb toom rau pej xeem thaum muaj xwm txheej ceev. Cov lus no tuaj yeem tshaj tawm los ntawm ntau txoj hauv kev, suav nrog xov tooj cua, TV, SMS, social media, thiab 5G networks. 5G network, nrog nws cov latency qis, muaj kev ntseeg siab, thiab muaj peev xwm loj, tau dhau los ua qhov tseem ceeb hauv PWS.
Message Broadcasting Mechanism in 5G PWS
Hauv 5G tes hauj lwm, PWS cov lus tau tshaj tawm los ntawm NR cov chaw nres tsheb txuas nrog 5G Core Network (5GC). NR cov chaw nres tsheb hauv paus yog lub luag haujlwm rau kev teem sijhawm thiab tshaj tawm cov lus ceeb toom, thiab siv cov haujlwm ua haujlwm kom ceeb toom rau Cov Khoom Siv (UE) tias cov lus ceeb toom tau tshaj tawm. Qhov no ua kom muaj kev tshaj tawm sai thiab nthuav dav ntawm cov ntaub ntawv xwm txheej ceev.
Main Categories of PWS in 5G
Av qeeg thiab Tsunami Warning System (ETWS):
Tsim los ua kom tau raws li kev ceeb toom ceeb toom ntsig txog av qeeg thiab / lossis cov xwm txheej tsunami. ETWS cov lus ceeb toom tuaj yeem raug faib ua cov ntawv ceeb toom tseem ceeb (kev ceeb toom luv luv) thiab cov ntawv ceeb toom thib ob (muab cov ncauj lus kom ntxaws), muab cov ntaub ntawv raws sij hawm thiab nthuav dav rau pej xeem thaum muaj xwm txheej ceev.
Commercial Mobile Alert System (CMAS):
Lub kaw lus ceeb toom rau pej xeem thaum muaj xwm txheej ceev uas xa cov ntawv ceeb toom xwm txheej ceev rau cov neeg siv los ntawm kev lag luam mobile network. Hauv 5G tes hauj lwm, CMAS ua haujlwm zoo ib yam li ETWS tab sis tuaj yeem npog ntau yam ntawm cov xwm txheej xwm txheej ceev, xws li huab cua hnyav thiab kev tawm tsam kev ua phem.
Key Features of PWS
Notification Mechanism for ETWS and CMAS:
Ob leeg ETWS thiab CMAS txhais txawv System Information Blocks (SIBs) kom nqa cov lus ceeb toom. Paging functionality yog siv los ceeb toom UEs txog ETWS thiab CMAS indications. UEs hauv RRC_IDLE thiab RRC_INACTIVE lub xeev saib xyuas ETWS/CMAS cov cim qhia thaum lawv lub sijhawm paging, thaum nyob hauv RRC_CONNECTED xeev, lawv kuj saib xyuas cov lus no thaum lwm lub sijhawm paging. ETWS/CMAS ceeb toom paging ua rau kom tau txais cov ntaub ntawv kaw lus yam tsis muaj ncua sij hawm mus txog rau lub sijhawm hloov kho tom ntej, ua kom muaj kev tshaj tawm cov ntaub ntawv xwm txheej ceev.
ePWS Enhancements:
Qhov Kev Tshaj Tawm Txog Kev Ceeb Toom Hauv Pej Xeem (ePWS) tso cai tshaj tawm cov ntsiab lus raws li cov ntsiab lus thiab cov ntawv ceeb toom rau UEs yam tsis muaj tus neeg siv cuam tshuam lossis tsis tuaj yeem tso cov ntawv nyeem. Qhov kev ua haujlwm no ua tiav los ntawm cov txheej txheem tshwj xeeb thiab cov qauv (xws li TS 22.268 thiab TS 23.041), kom ntseeg tau tias cov ntaub ntawv xwm txheej ceev mus txog qhov dav dav ntawm cov neeg siv.
KPAS thiab EU-Alert:
KPAS thiab EU-Alert yog ob qho kev ceeb toom pej xeem ntxiv uas tsim los xa ntau qhov kev ceeb toom ib txhij. Lawv siv tib yam Access Stratum (AS) cov txheej txheem raws li CMAS, thiab NR cov txheej txheem teev tseg rau CMAS yog sib npaug rau KPAS thiab EU-Alert, ua kom muaj kev sib raug zoo thiab kev sib raug zoo ntawm cov tshuab.
Hauv kev xaus, 5G Public Warning System, nrog rau nws cov kev ua tau zoo, kev ntseeg tau, thiab kev pabcuam dav dav, muab kev txhawb nqa kev ceeb toom xwm txheej ceev rau pej xeem. Raws li 5G thev naus laus zis txuas ntxiv txhim kho thiab txhim kho, PWS yuav ua lub luag haujlwm tseem ceeb dua hauv kev teb rau kev puas tsuaj ntuj tsim thiab teeb meem kev nyab xeeb rau pej xeem.
Lub tswv yim muaj ntau yam ntawm passive microwave Cheebtsam rau Lub 5G (NR, los yog Tshiab Xov tooj cua) Public Warning Systems: Fais fab Fais fab divider, directional coupler, filter, duplexer, as well as LOW PIM Cheebtsam mus txog 50GHz, nrog zoo zoo thiab kev sib tw nqi.
