Notes:
<context_name>
must be the name of the context where you want to enable IMS Authorization service.
<imsa_service_name>
must be the name of the IMS Authorization service to be configured for Rel. 7 Gx
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
msisdn-
prefix-from
<msisdn_prefix_from>
and
msisdn-prefix-to
<msisdn_prefix_to>
with the
starting and ending MSISDNs respectively.
To enable the Gx interface to connect to a specific PCRF for a specific subscriber, configure both
msisdn-
prefix-from
<msisdn_prefix_from>
and
msisdn-prefix-to
<msisdn_prefix_to>
with the same
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>
Important:
This command is obsolete in release 11.0 and later releases.
