VoLTESBC/P-CSCF收到主叫VoLTE终端发起的呼叫、VoLTESBC/P-CSCF呼叫被叫VoLTE终端,2种场景下,VoLTESBC/P-CSCF通过Rx接口指示PCRF通过Gx接口索取VoLTE主叫用户或VoLTE被叫用户的当前位置信息的路径正确的是()
A.漫游用户:漫游地VoLTESBC/P-CSCF→漫游地L-DRA→漫游地PCRF→漫游地L-DRA→漫游地P-GW/PCEF→归属地S-GW→漫游地MME→漫游地eNodeB→(后续沿原路径返回归属地VoLTESBC/P-CSCF,略)
B.漫游用户:漫游地VoLTESBC/P-CSCF→漫游地L-DRA→漫游地PCRF→漫游地L-DRA→漫游地P-GW/PCEF→漫游地S-GW→漫游地MME→漫游地eNodeB→(后续沿原路径返回归属地VoLTESBC/P-CSCF,略)
C.未漫游用户:归属地VoLTESBC/P-CSCF→归属地L-DRA→归属地PCRF→归属地L-DRA→归属地P-GW/PCEF→归属地S-GW→归属地MME→归属地eNodeB→(后续沿原路径返回归属地VoLTESBC/P-CSCF,略)
