8.137 Monitoring Event Extension Information
29.2743GPP3GPP Evolved Packet System (EPS)Evolved General Packet Radio Service (GPRS) Tunnelling Protocol for Control plane (GTPv2-C)Release 18Stage 3TS
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 shall be encoded as specified in clause 8.4.4 and 8.4.5 of 3GPP TS 29.336 [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 2-8 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 [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.
