Table 12.8.4.2: DLMC Frequency Parameters information element details

TSC (3 bit field)
This field is the binary representation of the training sequence code, see 3GPP TS 45.002. Range: 0 to 7.

ARFCN (10 bit field)
This field is the binary representation of the absolute radio frequency channel number (ARFCN) defined in 3GPP TS 45.005. Range 0 to 1023.

MA_NUMBER (4 bit field)
This field is the binary reference to a GPRS mobile allocation received in either the PSI2 information, the SI13/PSI13 information or a previous assignment message, see sub-clause 5.5.1.6. Range: 0 to 15.

CHANGE_MARK_1 (2 bit field)
CHANGE_MARK_2 (2 bit field)
These fields are the binary representations of the allowed values for the PSI or SI change mark associated with the GPRS mobile allocation that the MA_NUMBER field refers to. Range: 0 to 3.

GPRS Mobile Allocation (information element)
The GPRS Mobile Allocation information element is defined in sub-clause 12.10a.

HSN (6 bit field)
This field is the binary representation of the hopping sequence number, see 3GPP TS 45.002. Range: 0 to 63.

MA Frequency List contents (variable length octet string)
This variable length octet string is the representation of a set of radio frequency channels defining a GPRS mobile allocation. The encoding of the octet string is defined by the value part of the type 4 information element Frequency List, defined in 3GPP TS 44.018. The allowed formats of the Frequency List information element are the bit map 0, 1024 range, 512 range, 256 range, 128 range and variable bit map formats.
