Procedure

Establish a UE-PSTN voice call successfully



When the UE handover from 3G to 2G and end in 2G ,the 2G network will force the UE reselect from 2G to 3G

Remarks

RELOCATION REQUIRED – relocation target CID

HANDOVER REQUEST -- target CID in signal info container

PREPARE HANDOVER RESPONSE – Handover Number
