LOCATION UPDATE LUPISD
1 Do a Location update (LU) (i.e. switch on
the mobile phone) 2 LU distributed to an HLR-S 3
HLR-S requests and downloads the Subscriber data
from CUDB with an LDAPsearch message 4 HLR-S
processes the LU 5a HLR-S stores the new Location
data (VLR address) in the CUDB by means of
LDAPModify 5b Subscriber data change is
replicated to other CUDB nodes 6 HLR-S sends
Insert Subscriber Data (ISD) message to
the VLR and terminates the location update
operation

SUBSCRIBER AUTHENTICATION - SAI
1 Generate an Authentication operation
request by switching off and on a telephone
with a WCDMA or GSM subscription. 2 SAI
message distributed to one of the HLR-S 3 AUC
Subscriber Data is requested from the HLR to
the CUDB 4 AuC Subscriber Data is downloaded
from the CUDB 5 Decryption of eKi and generation
of Authentication Vectors???? 6 HLR/AuC
Server send the SAI response with the
Authentication Vectors

UDC interfaces and protocols

• OSS UDC components SNMPTelnet, sftp, SSH Used
  for OM purposes FM, CM, PM, SM
• 6. PG - HSS SOAP
• Used for notification of data changes towards
  HSS-FE
• 6. CUDB - HLR SOAP
• Used for notification messages due to SAE
  Mobility Management function

• HLR/AUC and HSS FE CUDB LDAP Used by the
  HLR/AuC FEs to access the data layer
• CAS Provisioning Server CAI3G, CLI, MML For
  the provision commands for the data layered
  architecture
• Provisioning Server HLR/AuC FE MMLUsed by the
  PG/PS for validation and notification request to
  the HLR/AuC FEs
• Provisioning Server CUDB LDAPUsed for
  accessing application data stored in CUDB to
  create, read, modify and delete user data
