Section: 8.137 Monitoring Event Extension Information
Content: The Monitoring Event Information contains the monitoring event parameters that are necessary to transfer over the S3/S16/S10 interface. The Monitoring Event Extension Information is coded as depicted in Figure 8.137-1. Figure 8.137-1: Monitoring Event Extension Information The SCEF Reference ID, the SCEF ID and the SCEF Reference ID Ext shall be encoded as specified in clause 8.4.4, 8.4.5 and 8.4.82 of 3GPP TS 29.336[ Home Subscriber Server (HSS) diameter interfaces for interworking with packet data networks and applications ]  [69]. The SCEF ID Length indicates the length of the SCEF ID in octets. The following bits within Octet 5 indicate: - Bit 1 – LRTP (Remaining Minimum Periodic Location Reporting Time Present): This flag is used to indicate that Remaining Minimum Periodic Location Reporting Time shall be present. - Bit 2 – SRIE (SCEF Reference Id Extension): if this flag is set to "1", the SCEF Reference ID Ext field shall be present to contain the 64-bit SCEF Reference ID Ext for the event. In this case, the receiver shall ignore the SCEF Reference ID received in octets 5 to 8. NOTE: The sender can set any value for SCEF Reference ID if the SCEF Reference ID Ext is included. - Bit 3-8 Spare. Remaining Minimum Periodic Location Reporting Time indicates the current value of the timer for minimum periodic location reporting. It shall be encoded as specified in clause 8.4.29 of 3GPP TS 29.336[ Home Subscriber Server (HSS) diameter interfaces for interworking with packet data networks and applications ]  [69]. The target MME/SGSN shall start the timer with the Remaining Minimum Periodic Location Reporting Time to continue detecting the location change. If the timer expires, the target MME/SGSN shall restart the timer with the value of the Periodic-Time AVP within the Monitoring-Event-Configuration AVP provided by the HSS.
