Table 12.64.2: DTM Handover PS Radio Resources 3 information element details

Cell Identification (information element)
This information element is defined in sub-clause 12.23.

MAX_LAPDm (3 bit field)
This field indicates the maximum number of LAPDm frames into which a layer 3 message can be segmented sent on the main DCCH. It is coded as described in 3GPP TS 44.018.

GPRS_MS_TXPWR_MAX_CCH (5 bit field)
The GPRS_MS_TXPWR_MAX_CCH field is coded as the binary representation of the ‘power control level’ in 3GPP TS 45.005 corresponding to the maximum TX power level a mobile station may use when accessing on a packet control channel. This value shall be used by the mobile station according to 3GPP TS 45.008.

GPRS Cell Options (information element)
The GPRS Cell Option information element is defined in sub-clause 12.24.

GPRS Power Control Parameters (information element)
The GPRS Power Control Parameters information element is defined in sub-clause 12.9a.

RLC_RESET (1 bit field)

This field is defined in sub-clause 12.42.

EGPRS mode 2 IE

This information element is defined in sub-clause 12.48a.1.

EMST_NW_Capability (1 bit field)

See sub-clause 11.2.29 (Packet Uplink Assignment message).

TFI (5 bit field)

See sub-clause 11.2.31 (Packet Timeslot Reconfigure message).

RLC_MODE (1 bit field)

See sub-clause 11.2.31 (Packet Timeslot Reconfigure message). If the RLC_RESET field indicates that any given RLC entity is not reset across PS handover then the mobile station shall ignore this field and use the same RLC mode that was used for the corresponding PFC in the old cell.

EGPRS Window Size
This information element is defined in sub-clause 12.5.2.

PFI (7 bit field)

See sub-clause 11.2.31 (Packet Timeslot Reconfigure message).

NPM Transfer Time (5 bit field)

This field contains the NPM Transfer Time limitation for TBF or RLC entity assigned to operate in RLC non-persistent mode. If EMSR is supported this field contains the NPM Transfer Time limitation for a specific Packet Flow Context configured to use RLC non-persistent mode.

MTTI_DOWNLINK_ASSIGNMENT_C1 (1 bit field)

MTTI_DOWNLINK_ASSIGNMENT_C2 (1 bit field)

See sub-clause 11.2.7 (Packet Downlink Assignment message).

MTTI_UPLINK_ASSIGNMENT_C1 (1 bit field)

MTTI_UPLINK_ASSIGNMENT_C2 (1 bit field)

See sub-clause 11.2.29 (Packet Uplink Assignment message).

EMSR Additional PFCs 1

EMSR Additional PFCs 2

EMSR Additional PFCs 3

See sub-clause 11.2.7 (Packet Downlink Assignment message).

EGPRS Packet Downlink Ack/Nack Type 3 Support (1 bit field)

See sub-clause 11.2.7 (Packet Downlink Assignment message).

Primary TSC Set (1 bit field)

Secondary DL TSC Set (1 bit field)

See sub-clause 12.46.

Primary TSC Value (3 bit field)

See sub-clause 12.46.

Secondary DL TSC Value (3 bit field)

See sub-clause 12.46.
