Figure 8.2.91-1: Additional Usage Reports Information
The Number of Additional Usage Reports value shall be encoded as an unsigned binary integer value on 15 bits. Bit 7 of Octet 5 is the most significant bit and bit 1 of Octet 6 is the least significant bit.
The bit 8 of octet 5 shall encode the AURI (Additional Usage Reports Indication) flag:
– when set to "1", it indicates that additional usage reports will follow. In this case, the Number of Additional Usage Reports value shall be set to "0" by the sender and ignored by the receiver;
– when set to "0", the Number of Additional Usage Reports value shall be set to the total number of additional usage reports to be sent in PFCP Session Report Request messages.
