DataBase Subsystems
Administrative Data Center
The Administrative Data Center (ADC) is customer supplied and may be used to
enter user information into the DAP and MSC Home Location Registers (HLRs).
Dispatch Application Processor
Dispatch Call Processing uses data in the DAP to define and control access to the
iDEN system and the system services.
DAP Home
Location Register
The Dispatch Home Location Register (D-HLR) is a DAP-resident database that
stores information about dispatch access rights and features allocated to each MS.
The D-HLR performs the Subscriber Access Control. It is queried each time a
dispatch call is initiated or call features are requested to manages access to the
system and services. The D-HLR database contains Mobile Station ID data and
Fixed Network data. Mobile Station ID data includes:
• International Mobile Equipment Identifier (IMEI)
• Billing Number or International Mobile Subscriber Identity (IMSI)
• Dispatch Individual ID
• Dispatch Group IDs
• Dispatch Fleet ID
•Urban ID
• Fleet, Talk Group, Fleet Member
Dispatch Home Location Register Fixed Network data includes:
• Services: Allow/Deny
• Private Call, Group Call, Call Alert, PTT ID
• Optional features (Priority and Emergency)
This data is loaded into the D-HLR database by individual service provider policies
and procedures often using the Administrative Data Center (ADC).
DAP Visited
Location Register
The DAP - Visited Location Register (D-VLR) is a Random Access Memory (RAM)
resident database that contains the most recent location information on each MS. As
an MS travels it reports its location to the DAP which updates the D-VLR with the
latest data. The D-VLR contains the MS ID, subscriber data and the current status of
the MS. The D-VLR is a very fast access database with data about recently active
and active MSs. It is a fast look up of authentication and services during Dispatch
call processing. The fast lookup helps reduce the call setup delay because the recent
list is shorter than the complete list in the D-HLR.
