Adax Solutions for the HSS
(Home Subscriber Server)
Adax Cavium-based products have the processing power to host the
combined HLR and AuC functions within the HSS and deliver the
security and signaling requirements to specific Diameter interfaces.
Adax’ integrated IPsec with SCTP functionality allows developers
tightly coupled Diameter services. The Adax QuickPort programming
and cross-compile environment makes developers feel at home right
away and allows them to port their application from their current
host onto the PacketRunner quickly and efficiently.
HSS – Home Subscriber Server
The HSS combines
the HLR (Home Location Register) and the AuC (Authentication Center) – two
functions already present in pre-IMS 2G/GSM and 3G/UMTS networks.
The HLR part of the HSS is in charge of storing
and updating, as needed, the database containing all the user subscription
information, including:
- User identification and addressing – this
corresponds to the IMSI (International Mobile Subscriber Identity)
and MSISDN
(Mobile Subscriber ISDN Number) or mobile telephone number.
- User profile information – this includes service subscription
states and user-subscribed Quality of Service information (such
as maximum allowed bit rate or allowed traffic class).
The AuC part of the HSS is in charge of generating security information
from user identity keys. This security information is provided
to the HLR and further communicated to other entities in the network.
Security information is mainly used for:
- Mutual network-terminal
authentication.
- Radio path ciphering and integrity protection,
to ensure data and signaling transmitted between the network
and the terminal is
neither eavesdropped nor altered.
