Configuring the S6d Diameter Interface (S4 Only)
This section describes how to configure the S6d Diameter interface to support S4 functionality.
The S6d interface is a Diameter-based interface used to support S4 functionality by enabling the S4-SGSN to
communicate with the HSS. The HSS is a master user database that contains all subscription related information, and
performs the following functions:
communicate with the HSS. The HSS is a master user database that contains all subscription related information, and
performs the following functions:
Authentication and authorization of the user
Provides the subscribers location information
Provides the subscribers IP information
To support the S6d interface, an HSS Peer Service must be configured and associated with a Diameter endpoint. This
HSS Peer Service is then associated with the configured SGSN and/or GPRS services to enable communication with the
HSS via the S6d interface. Optionally, operators can configure an operator policy-based interface selection.

Configuring the S6d interface consists of the following procedures:
1. Configuring a Diameter Endpoint for the S6d interface
2. Configuring the HSS Peer Service and Interface Association for the S6d interface
3. Associating the HSS Peer Service with the SGSN and GPRS Services for the S6d interface.
4. Optional. Configuring operator policy-based interface selection for the S6d interface.

4. Optional. Configuring operator policy-based interface selection for the S6d interface.
Configuring the Diameter Endpoint for the S6d Interface
Use the following procedure to configure the Diameter endpoint for the S6d interface:
Step 1
Configure a port that will be bound to an interface (at step 3) to be used as the S6d interface.
Step 2
Configure an Ethernet interface to be used as a diameter endpoint.
Step 3
Configure a Diameter endpoint to be used as the S6d interface.
Step 4
Specify the origin host address and the IP address of the Ethernet interface to be used as the S6d interface.
Step 5
Specify the origin realm. The realm is the Diameter identity. The originator’s realm is present in all Diameter messages
and is typically the company or service provider’s name.
and is typically the company or service provider’s name.
Step 6
Specify the peer name, peer realm name, peer IP address and port number. The peer IP address and port number are the
IP address and port number of the HSS.
IP address and port number of the HSS.
Step 7
Specify the route entry peer. This parameter is optional. The route entry peer parameter is required if multiple HSS
peers are configured under a Diameter point and operators want to associate a routing weight to each HSS peer so that
the S4-SGSN contacts each HSS based on the weight distribution.

Step 8
Optional. Enable or disable the
watchdog-timeout
parameter.
Step 9
The
use-proxy
keyword can be specified in the
diameter-endpoint
command to enable the proxy mode. The usage
of proxy mode depends on the operator’s HSS capabilities.
