Gx Policy Event Trigger Values
MATRIXX Policy includes default event trigger definitions.
Default Gx Event Trigger Values lists the default supported event triggers. You
can add to this list by adding an event trigger in My MATRIXX. For more information, see the discussion about event triggers.
| Trigger Name | Trigger Value | Description |
|---|---|---|
| SGSN_CHANGE | 0 | Change in the serving Service GPRS Support Node (SGSN) address. |
| QOS_CHANGE | 1 | Change of Quality of Service (QoS). |
| RAT_CHANGE | 2 | Change of Radio Access Technology (RAT) type. |
| TFT_CHANGE | 3 | Change in the Traffic Flow Template (TFT). |
| PLMN_CHANGE | 4 | Change of SGSN Mobile Network Code (MNC) Mobile Country Code (MCC) tuple. |
| LOSS_OF_BEARER | 5 | Bearer associated with PCC rules was lost. |
| IP-CAN_CHANGE | 7 | Change of IP Connectivity Access Network (IP-CAN) type. |
| QOS_CHANGE_EXCEEDING_AUTHORIZATION | 11 | Change in requested QoS beyong the authorized values for a specific bearer. |
| RAI_CHANGE | 12 | Change in Routing Area Identity (RAI). |
| USER_LOCATION_CHANGE | 13 | Change in user location. |
| NO_EVENT_TRIGGERS | 14 | No event triggers associated with the Gx session. |
| OUT_OF_CREDIT | 15 | Credit limit was reached. |
| REALLOCATION_OF_CREDIT | 16 | Subsequent quota granted. |
| REVALIDATION_TIMEOUT | 17 | Upon revalidation timeout, Policy and Charging Enforcement Function (PCEF) informs the Policy and Charging Rules Function (PCRF). |
| UE_IP_ADDRESS_ALLOCATE | 18 | Allocate an IPv4 address for a dual-stack capable UE. |
| UE_IP_ADDRESS_RELEASE | 19 | Release an IPv4 address for a dual-stack capable UE. |
| DEFAULT_EPS_BEARER_QOS_CHANGE | 20 | Change in the Evolved Packet System (EPS) Bearer QoS. |
| AN_GW_CHANGE | 21 | Change of serving Access Node Gateway Address. |
| SUCCESSFUL_RESOURCE_ALLOCATION | 22 | Resources for a rule were successfully allocated. |
| RESOURCE_MODIFICATION_REQUEST | 23 | PCC rules were requested for a resource modification request initiated by the UE. |
| PGW_TRACE_CONTROL | 24 | Trace activation or deactivation request for the Packet Data Network Gateway (P-GW). Trace activation is indicated with the Trace-Data AVP (TraceData MDC field) with relevant trace parameters. Trace deactivation is indicated with the Trace-Reference AVP (TraceId MDC field). |
| UE_TIME_ZONE_CHANGE | 25 | The time zone in which the UE is located has changed. The new value of the UE's time zone is indicated in the 3GPP-MS-TimeZone AVP. |
| TAI_CHANGE | 26 | Change in the Tracking Area Identity (TAI). |
| ECGI_CHANGE | 27 | Change in the E-UTRAN Cell Global Identifier (ECGI). |
| CHARGING_CORRELATION_EXCHANGE | 28 | Reports the access network charging identifier. |
| APN_AMBR_MODIFICATION_FAILURE | 29 | APN AMBR modifications failed. |
| USER_CSG_INFORMATION_CHANGE | 30 | Change in the Closed Subscriber Group (CSG) information. |
| USAGE_REPORT | 33 | Reports accumulated usage volume when the usage threshold provided by the Application Function (AF) has been reached. |
| DEFAULT_EPS_BEARER_QOS_MODIFICATION_FAILURE | 34 | Default EPS Bearer QoS modifications failed. |
| USER_CSG_HYBRID_SUBSCRIBED_INFORMATION_CHANGE | 35 | A user enters or leaves a hybrid cell to which the user is subscribed. |
| USER_CSG_HYBRID_UNSUBSCRIBED_INFORMATION_CHANGE | 36 | A user enters or leaves a hybrid cell to which the user is not subscribed. |
| ROUTING_RULE_CHANGE | 37 | Change in a routing rule |
| MAX_MBR_APN_AMBR_CHANGE | 38 | 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. |
| APPLICATION_START | 39 | An application has started. |
| APPLICATION_STOP | 40 | An application has stopped. |
| ADC_REVALIDATION_TIMEOUT | 41 | Cause the PCEF to trigger a PCRF interaction to request ADC rules from the PCRF for an established IP CAN session. |
