Configuring IMS Authorization Service at Context Level
Use the following example to configure IMS Authorization Service at context level for IMS subscribers in
GPRS/UMTS networks:
configure
context
<context_name>
ims-auth-service
<imsa_service_name>
p-cscf table { 1 | 2 } row-precedence
<precedence_value>
{ address
<ip_address>
| ipv6-address
<ipv6_address>
}
p-cscf discovery { table { 1 | 2 } [ algorithm { ip-address-modulus | msisdn-
modulus | round-robin } ] | diameter-configured }
policy-control
diameter origin endpoint
<endpoint_name>
diameter dictionary
<dictionary>
failure-handling cc-request-type { any-request | initial-request | terminate-
request | update-request } { diameter-result-code { any-error |
<result_code>
[ to
<end_result_code>
] } } { continue | retry-and-terminate | terminate }
diameter host-select row-precedence
<precedence_value>
table { 1 | 2 } host
<host_name>
[ realm
<realm_name>
] [ secondary host
<host_name>
[ realm
<realm_name>
] ]
diameter host-select reselect subscriber-limit
<subscriber_limit>
time-
interval
<duration>
diameter host-select table { 1 | 2 } algorithm { ip-address-modulus | msisdn-
modulus | round-robin }
end
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 the Gx
interface authentication.
A maximum of 16 authorization services can be configured globally in a system. There is also a system limit for
maximum number of total configured services.
Secondary P-CSCF IP address can be configured in the P-CSCF table. Refer to the
Command Line Interface
Reference
for more information on the
p-cscf table
command.
To enable Rel. 6 Gx interface support, specific Diameter dictionary must be configured. For information on the
Diameter dictionary to use, contact your Cisco account representative.
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>
