Table 12.42a.2: PS Handover Radio Resources 2 information element details

Handover Reference (8 bit field)
This field contains the reference value to be used when performing PS Handover. The field is encoded as the contents of the Handover Reference information element as defined in 3GPP TS 44.018.

ARFCN (10 bit field)
This field contains the BCCH frequency of the new cell. This field is encoded as the ARFCN defined in 3GPP TS 44.018.

Range: 0 to 1023.

SI (2 bit field)
The Synchronization Indication (SI) field indicates which type of PS Handover is to be performed.

Bit
2 1
0 0 Non-synchronized
0 1 Synchronized
1 0 Pre-synchronised
1 1 reserved

NCI (1 bit field)
The Normal Cell Indication (NCI) field indicates how the MS shall behave in case of out of range timing advance values.

Bit
1
0 Out of range timing advance is ignored
1 Out of range timing advance shall trigger a handover failure procedure.
