interface authentication.
 A maximum of 16 authorization services can be configured globally in a system. There is also a system limit for
the maximum number of total configured services.
 To enable Rel. 7 Gx interface support, pertinent Diameter dictionary must be configured. For information on the
specific Diameter dictionary to use, contact your Cisco account representative.
 When configuring the MSISDN prefix range based PCRF selection mechanism:
To enable the Gx interface to connect to a specific PCRF for a range of subscribers configure
prefix-from <msisdn_prefix_from>
starting and ending MSISDNs respectively.
To enable the Gx interface to connect to a specific PCRF for a specific subscriber, configure both
prefix-from <msisdn_prefix_from>
MSISDN.
In StarOS 8.1 and later releases, per MSISDN prefix range table a maximum of 128 rows can be added. In
StarOS 8.0 and earlier releases, a maximum of 100 rows can be added.
The MSISDN ranges must not overlap between rows.
 The Round Robin algorithm for PCRF selection is effective only over a large number of PCRF selections, and
not at a granular level.
 Optional: To configure the Quality of Service (QoS) update timeout for a subscriber, in the IMS Authorization
Service Configuration Mode, enter the following command:
qos-update-timeout <timeout_duration>
must be the name of the context where you want to enable IMS Authorization service.
must be the name of the IMS Authorization service to be configured for Rel. 7 Gx
Important:
This command is obsolete in release 11.0 and later releases.
