• From Spec
  • (ng-5G-S-TMSI)=(AMF Set ID)+(AMF Pointer)+(5G-TMSI)
    (48 bits)=(10 bits)+(6 bits)+(32 bits)
    


• 【Tool_1】Enter 48 bits from QXDM [0xB821] PCCH / Paging. It will calculate the (AMF_SET_ID)(AMF_Pointer)(_5g_tmsi[0])(_5g_tmsi[1])(_5g_tmsi[2])(_5g_tmsi[3])
  • ue-Identity ng-5G-S-TMSI :
    Convert

• 【Tool_2】Enter QXDM [0xB80A] Registration accept (AMF_SET_ID)(AMF_Pointer)(_5g_tmsi[0])(_5g_tmsi[1])(_5g_tmsi[2])(_5g_tmsi[3]), it will calculate the 48 bits [0xB821] PCCH / Paging "ue-Identity ng-5G-S-TMSI"
  • Enter the following decimal parameters:
    • AMF_SET_ID:
      
    • AMF_Pointer:
      
    • _5g_tmsi[0]:
      
    • _5g_tmsi[1]:
