> 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
