為滿足多(duo)應(ying)急(ji)處置(zhi)部門(men)的高效聯(lian)動(dong)(dong)、重要用戶優先呼叫等應(ying)急(ji)通信(xin)指(zhi)揮需求，集群通信(xin)是在現(xian)場進行無線(xian)指(zhi)揮調度(du)(du)和應(ying)急(ji)聯(lian)動(dong)(dong)的有效手段。集群通信(xin)的快速呼叫、群組呼叫、強插強拆、優先呼叫、脫(tuo)網直(zhi)通等特(te)點，特(te)別適用于城(cheng)市(shi)(shi)應(ying)急(ji)聯(lian)動(dong)(dong)以及(ji)現(xian)場應(ying)急(ji)通信(xin)指(zhi)揮。多(duo)個固(gu)定集群基站采用多(duo)區組網方(fang)式實現(xian)城(cheng)市(shi)(shi)中(zhong)心及(ji)周(zhou)邊地的無線(xian)覆蓋，能夠(gou)將公(gong)安、城(cheng)管、消防、急(ji)救等重要部門(men)納入統一(yi)的城(cheng)市(shi)(shi)固(gu)定應(ying)急(ji)聯(lian)動(dong)(dong)平臺。另外，集群車(che)載臺、便攜臺、手持(chi)機等用戶終端(duan)通常能夠(gou)第(di)一(yi)時間進入現(xian)場，快速開通，進行移動(dong)(dong)通信(xin)指(zhi)揮調度(du)(du)。
解決方案
以PDT/TETRA集群通(tong)(tong)(tong)信(xin)(xin)系統為(wei)核心(xin)構建(jian)(jian)應(ying)(ying)(ying)急(ji)通(tong)(tong)(tong)信(xin)(xin)網（政務(wu)(wu)共(gong)(gong)網），應(ying)(ying)(ying)急(ji)通(tong)(tong)(tong)信(xin)(xin)網（政務(wu)(wu)共(gong)(gong)網）建(jian)(jian)設(she)堅持“平(ping)戰(zhan)結合、平(ping)災兼顧”的(de)(de)(de)原則。應(ying)(ying)(ying)急(ji)狀(zhuang)態下(xia)，是一個覆蓋(gai)市、區、街鎮各(ge)級、各(ge)類應(ying)(ying)(ying)急(ji)管(guan)(guan)理工(gong)(gong)作(zuo)機構的(de)(de)(de)應(ying)(ying)(ying)急(ji)指揮通(tong)(tong)(tong)信(xin)(xin)網絡，為(wei)政府各(ge)職能部(bu)(bu)門(men)、應(ying)(ying)(ying)急(ji)管(guan)(guan)理工(gong)(gong)作(zuo)機構和基(ji)層(ceng)單元應(ying)(ying)(ying)對各(ge)種突發公共(gong)(gong)事(shi)件提供(gong)便捷(jie)通(tong)(tong)(tong)暢的(de)(de)(de)指揮通(tong)(tong)(tong)信(xin)(xin)。?而(er)在常態下(xia)，??是一個面向各(ge)級政府職能部(bu)(bu)門(men)、應(ying)(ying)(ying)急(ji)管(guan)(guan)理工(gong)(gong)作(zuo)機構和基(ji)層(ceng)單元的(de)(de)(de)日常無線通(tong)(tong)(tong)信(xin)(xin)網絡，為(wei)政府各(ge)職能部(bu)(bu)門(men)、應(ying)(ying)(ying)急(ji)管(guan)(guan)理工(gong)(gong)作(zuo)機構和基(ji)層(ceng)單元的(de)(de)(de)日常行(xing)政管(guan)(guan)理和生產作(zuo)業調度提供(gong)服務(wu)(wu)。
