MDN/MSISDN value is retained during the lifetime of call, including handoffs between P-GW and services like eHRPD/trusted/untrusted WiFi. As a result, all Rf records of a session have the same MDN/MSISDN values.

Disabled by default. If disabled, the MDN/MSISDN value received in the CS request is used and the S6b authorized MDN/MSISDN is lost during handoffs. As a result, different values of MDN/MSISDN are sent in the Rf records.

apn-ambr-always-include

Always includes APN-AMBR IE in Create Session Response.

bitrates-rounded-down-kbps

Bit rate granularity provided by different interfaces was not originally aligned in 3GPP specifications. For example, the PCRF provided bits per second on the Gx and the GTP utilized kilobits per second. Due to the conversion of bps to kbps, there were scenarios where the rounding off could have resulted in the incorrect allocation of MBR/GBR values.

When this keyword is disabled, a bitrate value sent on GTP interface will be rounded up if the conversion from bps (received from Gx) to kbps results in a fractional value. However, the enforcement of bitrate value (AMBR, MBR, GBR) values will remain the same. Once the value (in kbps) that is sent towards the Access side, it needs to be rounded up. Also, show subscribers pgw-only full all will show the APN-AMBR in terms of bps.

When enabled, the previous behavior of rounded-down kpbs bitrate (AMBR, MBR, BGR) values being sent towards the Access side is enforced. In addition, show subscribers pgw-only full all displays in terms of kpbs.

By default, this command is configured to use rounded-up bitrate values.

reject-cause { no-resource [ s6b-link-failure ] { s6b-retry-code } }

For S6b interface, it modifies the GTPv2 cause code from 92/0x5C (user authentication failure) to 73/0x49 (no resource available) when S6b server is unreachable due to no-connection or unstable connection and for Diameter server result codes—3002, 3004, 3005 and 5198.

reject-cause : Configures options for handling response with reject-cause.

no-resource : Configures handling for Create Session Response with cause code no-resource.

s6b-link-failure : Responds with no-resource for S6b server unreachability during authentication.

s6b-retry-code : Respond with no-resource for S6b diameter result-code(s) 3002, 3004, 3005, 5198.

cause-code temp-fail timeout sec retry retries

Enables eGTP Cause Code Handling when the P-GW receives a temporary failure response from peer (cause code 110). By default, this option is disabled.

When enabled, all transactions that were moved to pending queue because of temporary cause failure would be re-attempted after the temporary failure timer expires. After timer expiry, the P-GW informs PCRF about the transient failure. PCRF sends new Re-Auth-Request (RAR) and Create Bearer Request (CBR)/Modify Bearer Request (MBR)/Update Bearer Request (UBR) would succeed.

timeout sec : Specifies the time to wait (in seconds) before re-attempting the CBR/MBR/UBR.

sec must be an integer from 1 to 100.

retry retries : Specifies the maximum number of retries. The P-GW discards CBR/MBR/UBR after the maximum number of retries are exceeded.

retries must be an integer from 1 to 4.

create-session-rsp

Provides an option to include APN-AMBR in the Create Session Response.

gngp-modify-bearer-rsp-with-apn-ambr

Sends Modify Bearer Response with APN-AMBR only for GnGp Handoff. By default, this option is disabled.

modify-bearer-cmd-negotiate-qos

This configuration only impacts the P-GW QoS negotiation behavior when PCRF is unreachable or disabled, or event trigger is not registered while handling Modify Bearer Command. By default, this configuration is disabled.

When enabled, P-GW will always enforce previous QoS values, which is already applied. When disabled, the P-GW will always accept new QoS values (APN-AMBR/Def-EPS-Bearer-QoS) received in Modify Bearer Command.

modify-bearer-rsp { charging-fqdn-or-gw-addr | charging-id | msisdn }

Configures parameters in Modify Bearer Response messages from P-GW service. All parameters will be disabled by default.

• charging-fqdn-or-gw-addr : Sends Modify Bearer Response with Charging FQDN or Charging Gateway address whichever is present.

• charging-id : Sends Modify Bearer Response with Charging-ID.

• msisdn : Sends Modify Bearer Response with MSISDN.

overcharge-protection [ drop-all | transmit-all ]

Configures overcharging protection by temporarily not charging during loss of radio coverage. By default, this configuration is disabled.

drop-all : Configures overcharging protection to drop all packets received in LORC.

transmit-all : Configures overcharging protection to send all packets received in LORC mode to S-GW.

s2b-ho-paa-mismatch { allow | reject } [ ims-only ]

This command configures the behavior of an S2B handover at P-GW when there is a PAA mismatch for a given APN with a different PAA for the same APN.

• allow : Accepts a new call after clearing the existing LTE/S2B session when the P-GW receives a S2B handover request

• reject : Rejects a new call after clearing the existing LTE/S2B session when the P-GW receives a S2B handover request with a different PAA for the same APN.

• ims-only : Enable this behavior for an ims-only APN. By default, its applicable to all APNs when enabled.

seconds must be an integer from 1 to 3600.

Default: 0 (disabled).

On S-GW failure indication, P-GW shall check if S-GW Restoration feature is enabled or not. If enabled, P-GW shall maintain all the affected sessions for session-hold timeout. After session-hold timeout, P-GW shall clear all the sessions which are not recovered yet.

suppress-ubr no-bitrate-change

Enables the P-GW to suppress the Update Bearer Request (UBR) message UBR if the bit rate is the same after the round-off.

As the bit rate is expressed in bps on Gx and kbps on GTP, the P-GW does a round-off to convert a Gx request into a GTP request. When the P-GW receives a RAR from the PCRF with minimal bit rate changes (in bps), a UBR is sent, even if the same QoS (in kbps) is already set for the bearer. The UBR suppression feature enables the P-GW to suppress such a UBR where there is no update for any of the bearer parameters.

When the UBR has multiple bearer contexts, the bearer context for which the bit rate change is less than 1 kbps after round-off is suppressed. If other parameters, such as QCI, ARP, and TFT, that might trigger an UBR are changed and there is no change in bit rates after round-off, then UBR is not suppressed. Suppression of UBR is applicable for UBR triggered by CCA-I, RAR, and Modify Bearer Command.

Default: disabled. This means that the UBReq should be triggered even if the Gx and GTP bit-rates in kbps are same after round-off.

If the no option is used, it will disable this feature. That is, the UBReq should be triggered even if the Gx and GTP bit-rates in kbps are same after round-off.

There is no separate default keyword for this feature. Use the no option to revert to the default behavior.

Important

The UBR Suppression Feature is a licensed-controlled feature. Contact your Cisco account or service representative for detailed licensing requirements.

Allows drift time configuration to take care of NTP drift issues.

default

Sets drift time to 180 seconds.

If P-GW detects drift less than 180 seconds, it will check for condition "MWT + ReceivedTimeStamp (time from MME) > CurrentTimeStampAtPGW", and based on that P-GW will reject the call. If this condition is not met, it will transparently forward MWT and timestamp to AAA/Gx/Gy interfaces.

no

Disables message timestamp drift. MWT and received timestamp will not be passed on to all AAA/Gx/Gy interfaces.

message-timestamp-drift time_in_seconds

Configures the drift time from the message timestamp, in seconds, up to which P-GW will consider processing the message timestamp and max-wait-time (MWT) IEs.

If the create-time from MME is off from the currenttime by configured-drift-duration, then this could lead to a high NTP drift and session uniqueness falls back to using currenttime toward Diameter servers.

If the timestamp received in CSReq is significantly off (more than configured drift), then P-GW will not take action based on MWT and received timestamp and will transparently pass it to all AAA/Gx/Gy interfaces.

When received drift is less than configured limit, P-GW will reject the call if "MWT + ReceivedTimeStamp > CurrentTimeStampAtPGW" condition is met. Otherwise, P-GW will forward the timestamp and MWT to AAA/Gx/Gy interfaces.

time_in_seconds must be an integer from 0 to 1000.

Default: 180

Configures the P-GW to accept or reject requests for a static IP address if the address is already in use by another session.
