PUSI: in the SIP URI or TEL URI format

3.1.3 IPv4 or IPv6 AddressThe HSS9820 supports the IPv4 and IPv6 stacks. It enables a subscriber to access the IMS network by using the IPv4 or IPv6 address.



3.2 Implicit RegistrationThe HSS9820 supports implicit registration. A set of IMPUs or PUSIs forms an implicit registration set (IRS). After an IMPU or PUSI is registered, other IMPUs or PUSIs in the IRS are registered accordingly.

3.3 AuthenticationThe HSS9820 supports the following authentication schemes:

IMS authentication and key agreement (AKA) authentication

It is a standard 3GPP authentication scheme which provides ID authentication to access the IMS network for standard IMS UEs.

Early AKA authentication

It allows the GSM or UMTS subscribers whose authentication data are stored in the HLR to access the IMS network when both HSS and HLR exist.

Early IMS security

It allows the PS subscribers who do not support the IMS AKA authentication to access the IMS network. In this way, the IMS network is compatible with the current PS network.

HTTP Digest authentication

It is a cryptogram based authentication which allows a fixed network subscriber who does not support the IMS AKA authentication to access the IMS network.

NASS bundled authentication (NBA)

It allows the Network Attachment Subsystem (NASS) fixed UEs to access the IMS network.

If user equipment (UE) supports more than one scheme, the HSS9820 negotiates with the S-CSCF to choose one with the highest priority.

3.4 Charging SupportThe HSS9820 supports the following event charging and charging collection functions:

Primary event charging function (PECF)

Secondary event charging function (SECF)

Querying subscriber data in batches

You can export the subscriber data from the HSS in batches and save the data as a file.

Providing offline statistics function

You can export the subscriber data from the HSS to external database. In this way, the network operator can make statistics of the data based on specific query condition, thus providing reliable data for policy analysis and decision.

3.8 Disaster RecoveryThe HSS9820 serves as the core database in the IMS network. It stores subscription data and supports call or session setup. Because of its important network position, failures of the HSS9820 may cause a great loss to operators or subscribers.

The HSS9820 provides the 1+1 mated redundancy solution to protect the benefits of network operators and subscribers. In this solution, the two HSSs, which are located in different areas, work in active and standby mode. Both of them are connected to the peer MEs, and the data on them is synchronized on a real time basis. In normal cases, all the services are processed on the active HSS. The standby HSS takes over the services if the active HSS fails.

3.9 Template ManagementTo facilitate subscriber data management, the HSS allows you to define subscribers through a template.

The template management involves:

Managing system data through a template

Managing subscriber data through a template

Adding subscriber data through a template



You can predefine a service data template for the subscribers to be provided with the same services. When defining a subscriber, you only need to specify the subscriber ID and template ID.

3.10 NASS Nomadism ControlThe NASS nomadism control supported by the HSS involves:

Controlling the delivery of the nomadism location information

Controlling the delivery of the nomadism state

Setting and querying the nomadism authority in the business hall (BNH)

Setting and querying reference location information in the BNH

When a fixed network subscriber accesses the IMS network, the HSS checks whether the subscriber has the nomadism authority. The HSS then updates the nomadism state and the dynamic nomadism location information and delivers the information to the AS.

Through the BNH, you can set the NASS nomadism control ID. Each ID maps one template that contains the accessible and/or the inaccessible nomadic addresses.
