Parameters in octets 5 to 14, p to q, u, v, w and y to z shall be encoded as specified in 3GPP TS 32.422 [18]. If Length of Area Scope equals zero, then Area Scope octets p to q shall not be present.
If CRRMI (Collection period for RRM measurements LTE Indicator), bit 1 of octet ‘s’, is set to "1", then the Collection period for RRM measurements LTE parameter field shall be present, otherwise octet ‘u’ shall not be present.
If MPI (Measurement period LTE Indicator), bit 2 of octet ‘s’, is set to "1", then the Measurement period LTE parameter field shall be present, otherwise octet ‘v’ shall not be present.
If PMI (Positioning Method Indicator), bit 3 of octet ‘s’, is set to "1", then the Positioning Method parameter field shall be present, otherwise octet ‘w’ shall not be present.
If PLI (PLMN List Indicator), bit 4 of octet ‘s’, is set to "1", then the Number of MDT PLMNs and MDT PLMN List parameters shall be present, otherwise octet ‘x’ and octets ‘y to z’ shall not be present.
The value of the Number of MDT PLMNs represents the number of 3-octet PLMNs contained within the MDT PLMN List parameter and shall be a number from 1 to 16. Each PLMN ID in the list shall be encoded as defined for octets 5 to 7 in clause 8.18.
