看LOG學(xué)5G(63)-NSA錨點(diǎn)小區(qū)下發(fā)的切換命令

看LOG學(xué)5G(63)--NSA錨點(diǎn)小區(qū)下發(fā)的切換命令在NSA網(wǎng)絡(luò)中終端按照服務(wù)小區(qū)的測(cè)量配置對(duì)4G小區(qū)和5G小區(qū)進(jìn)行測(cè)量；根據(jù)測(cè)量報(bào)告配置上報(bào)4G和5G服務(wù)小區(qū)和鄰區(qū)的測(cè)量報(bào)告;請(qǐng)參看:看LOG學(xué)5G(62)--NSA中終端上報(bào)的測(cè)量報(bào)告)

圖1.支持雙連接UE上報(bào)的測(cè)量報(bào)告1.NSA網(wǎng)絡(luò)切換4G錨點(diǎn)小區(qū)收到終端的測(cè)量報(bào)告后，根據(jù)測(cè)量報(bào)告中的鄰區(qū)測(cè)量結(jié)果選定目標(biāo)小區(qū)；通過(guò)X2與目標(biāo)(站點(diǎn))小區(qū)進(jìn)行協(xié)商，開啟切換流程；

2.NSA網(wǎng)絡(luò)切換類型NSA網(wǎng)絡(luò)根據(jù)MN和SN服務(wù)小區(qū)的(切換)改變方式有兩種方式：站內(nèi)小區(qū)變更、站內(nèi)切換、進(jìn)一步劃分場(chǎng)景如下表所示：場(chǎng)景實(shí)現(xiàn)流程場(chǎng)景11-1

LTE錨點(diǎn)不變，NR站內(nèi)小區(qū)變更1-2

LTE錨點(diǎn)不變，NR站內(nèi)小區(qū)變更場(chǎng)景22-1
