CSCF PCRF-Policy-Control Configuration Mode Commands

 

The PCRF-Policy-Control Configuration Mode is used to enable PCRF policy control within the service.

Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

authorization mediatype

Enables media authorization, using external PCRF via Rx, of specific media types (present in the SDP of a SIP message) only.

Product

SCM (P-CSCF, A-BG)

Privilege

Administrator

Syntax

[ no ] authorization mediatype { application | audio | control | data | message | others | text | video }

mediatype { application | audio | control | data | message | others | text | video }

Enables the external authorization of calls for the following SDP media types:

•	application

•

audio

•

control

•

data

•

message

•

others

•

text

•

video

no

Disables external authorization for the specified media type.

Usage

As Per 3GPP 29.214V8.5, P-CSCF/A-BG will authorize VOIP calls only for the media types enabled via this command. The P-CSCF/A-BG sends all media information for all supported media types present in SDP in AAR message to PCRF via Rx. For the other (unsupported) media types, P-CSCF will not send media information in AAR.

Be default, media authorization for all the media types is enabled.

Example

Enables the P-CSCF to authorize calls for audio media types:

authorization mediatype audio

Disables the authorization of calls for audio media types:

no authorization mediatype audio

authorization policy-interworking-failure

Allows/rejects a session based on configuration in case of failure from PCRF.

Product

SCM (P-CSCF, A-BG)

Privilege

Administrator

Syntax

authorization policy-interworking-failure { session-continue | session-reject [ response-code code ] )

default authorization policy-interworking-failure

session-continue

P-CSCF continues session in case of failure from PCRF.

session-reject

P-CSCF rejects session in case of failure from PCRF.

response-code code

Specifies SIP response code for rejected session.

number must be an integer from 400 to 699. Default is 500.

default

By default, session-reject is activated to reject session with default response code 500.

Usage

Use this command to configure for policy interworking failure. Allow or reject a session based on configuration in case of failure from PCRF.

Example

The following command rejects session in case of failure from PCRF with SIP response code 450:

authorization policy-interworking-failure session-reject response-code 450

end

Exits the current mode and returns to the Exec Mode.

Product

All

Privilege

Administrator

Syntax

end

Usage

Change the mode back to the Exec mode.

exit

Exits the current mode and returns to the previous mode.

Product

All

Privilege

Administrator

Syntax

exit

Usage

Return to the previous mode.

signaling-bearer-loss

Enables subscription to Notification of Signaling Transmission Path Status, as well as IPCAN Change type notification. This command is enabled by default.

Product

SCM (P-CSCF, A-BG)

Privilege

Administrator

Syntax

[ no ] signaling-bearer-loss subscription

no

Disables subscription to Notification of Signaling Transmission Path Status, as well as IPCAN Change type notification.

subscription

Enables subscription to Notification of Signaling Transmission Path Status, as well as IPCAN Change type notification.

Usage

Use this command to enable or disable subscription to Notification of Signaling Transmission Path Status, as well as IPCAN Change type notification.

When enabled, the P-CSCF/A-BG sends AAR to the external PCRF via the Rx interface after UE registration. When disabled, the P-CSCF/A-BG will not subscribe to any event during Registration with PCRF and no diameter session will be established.

Example

Enables subscription to Notification of Signaling Transmission Path Status, as well as IPCAN Change type notification:

signaling-bearer-loss subscription

Disables subscription to Notification of Signaling Transmission Path Status, as well as IPCAN Change type notification:

no signaling-bearer-loss subscription
