APN-AMBR_MODIFICATION_FAILURE The PCEF shall use this value to indicate to the PCRF that APN-AMBR modifications have failed. The PCEF shall use this value in a new CCR command that indicates the failure of either a PUSH initiated modification or a PULL initiated modification. This event trigger needs no subscription. Applicable to functionality introduced with the Rel8 feature as described in clause 5.4.1. Gx, Gxx
USER_CSG_INFORMATION_CHANGE The PCRF shall use this value to indicate a request of reporting the event that the user enters/leaves a CSG cell. When the user enters a CSG cell, the User-CSG-Information AVP shall also be provided with the event report in the CCR command. Applicable to functionality introduced with the Rel9 feature as described in clause 5.4.1. Gx, Gxx
USAGE_REPORT This value shall be used in a CCA and RAR commands by the PCRF when requesting usage monitoring at the PCEF. The PCRF shall also provide in the CCA or RAR command the Usage-Monitoring-Information AVP(s) including the Monitoring- Key AVP and the Granted-Service-Unit AVP. When used in a CCR command, this value indicates that the PCEF generated the request to report the accumulated usage Gx, Sd
DEFAULT-EPS-BEARER-QOS_MODIFICATION_FAILURE The PCEF shall use this value to indicate to the PCRF that Default EPS Bearer QoS modifications have failed. The PCEF shall use this value in a new CCR command that indicates the failure of either a PUSH initiated modification or a PULL initiated modification. This event trigger needs no subscription. Applicable to functionality introduced with the Rel8 feature as described in clause 5.4.1. Gx, Gxx
USER_CSG_HYBRID_SUBSCRIBED_INFORMATION_CHANGE The PCRF shall use this value to indicate a request of reporting the event that the user enters/leaves a hybrid cell that the user subscribes to. When the user enters a hybrid cell where the user is a member, the User-CSG-Information AVP shall also be provided with the event report in the CCR command. Applicable to functionality introduced with the Rel9 feature as described Gx, Gxx
USER_CSG_HYBRID_UNSUBSCRIBED_INFORMATION_CHANGE The PCRF shall use this value to indicate a request of reporting the event that the user enters/leaves a hybrid cell that the user does not subscribe to. When the user enters a hybrid cell where the user is not a member, the User-CSG-Information AVP shall be provided with the event report in the CCR command. Applicable to functionality introduced with the Rel9 of Gx Gx, Gxx
ROUTING_RULE_CHANGE When used in a CCR command, this value indicates that the PCEF generated the request because there has been a change in the IP flow mobility routing rules for flow mobility (installation/modification/removal of the IP flow mobility routing rule). The new IP flow mobility routing rule information shall be provided in the Routing‑Rule‑Definition AVP within the same CCR command. This event trig Gx
MAX_MBR_APN_AMBR_CHANGE When used in a CCR command, this value indicates that the PCEF generated the request because there has been a change of MBR/APN-AMBR, Maximum-Bandwidth AVP is required to be provided in the same request with the new value. This event trigger needs no subscription. Applicable only to 3GPP-GPRS and 3GPP-EPS access types. Gx, Gxx
APPLICATION_START This value shall be used in CCA and RAR commands by the PCRF to indicate that the PCEF shall inform the PCRF when the start of the application’s traffic for the application, required for detection, has been identified. When used in a CCR command, this value indicates that the PCEF identified the start of the corresponding application’s traffic for an application identified by a TDF-Applicatio Gx, Sd
APPLICATION_STOP This value shall be used in a CCA and RAR commands by the PCRF to indicate that the PCEF shall inform the PCRF when the stop of the application’s traffic for the application, required for detection, has been identified. When used in a CCR command, this value indicates that the PCEF identified the stop of the corresponding application’s traffic for an application identified by a TDF-Applicati Gx, Sd
ADC_REVALIDATION_TIMEOUT This value shall be used in CCA and RAR commands by the PCRF to indicate that upon ADC revalidation timeout, the PCEF shall inform the PCRF. When used in a CCR command, this value indicates that the PCEF generated the request because there has been an ADC revalidation timeout. Gx, Gxx
CS_TO_PS_HANDOVER This value shall be used in CCA and RAR command by the PCRF to indicate that upon a CS to PS Handover, the PCEF shall inform the PCRF. When used in a CCR command, this value indicates that the PCEF generated the request because there is a CS to PS handover. Applicable only to CS to PS SRVCC functionality feature (rSRVCC). Gx,Gxx
UE_LOCAL_IP_ADDRESS_CHANGE When used in a CCR command, this value indicates that the PCEF generated the request because the UE Local IP Address assigned by the Fixed Broadband Access has changed. The UE-Local-IP-Address AVP shall be provided in the same request. This event trigger does not require to be provisioned by the PCRF. Applicable to functionality introduced with the EPC-routed feature. Gx, Gxx
NB_LOCAL_IP_ADDRESS_CHANGE When used in a CCR command, this value indicates that the PCEF generated the request because the H(e)NB Local IP Address assigned by the Fixed Broadband Access has changed. The HeNB-Local-IP-Address AVP shall be provided in the same request. This event trigger does not require to be provisioned by the PCRF. Applicable to functionality introduced with the EPC-routed feature. Gx, Gxx
ACCESS_NETWORK_INFO_REPORT This value shall be used in CCA and RAR commands by the PCRF to indicate that upon completion of an IP-CAN bearer establishment, modification or termination procedure, or upon termination of the IP-CAN session, and if the AF requests the PCRF to report the access network information, the PCEF shall report the corresponding user location and/or UE Timezone to the PCRF accordingly. When used in a Gx, Gxx
