Octet 5 shall be encoded as follows:

– Bit 1 – MBQE (Measurement Before QoS Enforcement): when set to "1", this indicates a request to measure the traffic usage before QoS enforcement.

– Bit 2 – INAM (Inactive Measurement): when set to "1", this indicates that the measurement shall be paused (inactive).

– Bit 3 – RADI (Reduced Application Detection Information): when set to "1", this indicates that the Application Detection Information reported to the CP function, upon detecting the start or stop of an application, shall only contain the Application ID.

– Bit 4 – ISTM (Immediate Start Time Metering): when set to "1", this indicates that time metering shall start immediately when the flag is received.

– Bit 5 – MNOP (Measurement of Number of Packets): when set to "1", this indicate a request to measure the number of packets transferred in UL/DL/Total in addition to the measurement in octets when Volume based measurement applies.

– Bit 6 – SSPOC (Send Start Pause of Charging): when set to "1", this indicate that the UP Function shall send a Start Pause of Charging indication to the upstream GTP-U entity(s) when the Dropped DL Traffic Threshold is reached.

– Bits 7 – ASPOC (Applicable for Start of Pause of Charging): when set to "1", this indicate that UP Function the the URR is applicable for Start of Pause of Charging, so that it shall stop the usage measurement for the URR when receiving Start Pause of Charging indication from the peer downstream GTP-U entity.

– Bits 8 – CIAM (Control of Inactive Measurement): when set to "1", this indicates that the UP function shall read the current value of the "INAM" flag and stop (if "INAM" is set to "1") or resume (if "INAM" is set to "0") the usage measurement accordingly for the given URR with the "APSOC" flag set to "1". If the "CIAM" flag is set to 0 for a URR with the "ASPOC" flag set to "1", the UP function shall ignore the "INAM" flag received in the Measurement Information. The "CIAM" flag shall be ignored for a URR without the ASPOC" flag set to "1".

At least one bit shall be set to "1". Several bits may be set to "1", e.g. both MBQE and MNOP bits are set to "1".
