終端在5G(NR)網(wǎng)絡(luò)中的RNTI取值和用途

終端在5G(NR)網(wǎng)絡(luò)中根據(jù)其連接狀態(tài)的不同，標(biāo)識(shí)也不同；其中：RNTI(RadioNetworkTemporaryIdentifier)終端在無(wú)線網(wǎng)絡(luò)中的的動(dòng)態(tài)標(biāo)識(shí)，而C-RNTI是由基站分配給UE的動(dòng)態(tài)標(biāo)識(shí)，唯一標(biāo)識(shí)了一個(gè)小區(qū)空口下的UE，且只有處于連接態(tài)下的UE，C-RNTI才有效。整理kangguoying20200725
