Huawei USN cloud Paging scheme

Hello guys.
I got precise paging enabled with paging rule for voice.
Example: data paging > last eNB > last neighbor eNB
Voice> off

no paging group and TA list configured

Now how will voice paging(volte) works. When paging USN will page the Last TA that the UE latched?. Also what part in Hedex can I see the info?
