You define the following parameters for your emulated LTE Relay - RelayUE tab.

Ignore IPv6 Pdn Address Assignment	Select to enable the Realy UE to ignore the IPv6 PAA (Pdn Address Assignment) in the "Create Session Response" when PDN Type = both (IPv4/IPv6) on Home Address Type Type on SGW Nodal Test Configuration. Tcl parameter: LteRelayUeIgnorePaaIpv6En
RN PDN Index	Enter a value to indicate the number of Default Bearer designated as the LTERELAYUeRN. Must be less than the value of Default Bearers per Session on SGW Nodal Test Configuration. Default Bearers per Session on SGW Nodal Test Configuration must be greater than 1 for this field to be available. Default is 1. Tcl parameter: LteRelayUeRnPdnIndexEn Tcl parameter: LteRelayUeRnPdnIndex
RN APN AMBR	Select to enable APN Aggregate Maximum Bit Rate Information. Setting and behavior same as GTPv2 APN Aggregate Maximum Bit Rate Information. Tcl parameter: LteRelayUeRnAmbrEn
RN Vendor Class ID	Enable to enter Vendor Class ID. Click to use the Auto-Increment Format Wizard. Tcl parameter: LteRelayUeRnVendorClassIdEn Tcl parameter: LteRelayUeRnVendorClassId

APN Aggregate Maximum Bit Rate Information

The APN Aggregate Maximum Bit Rate (RN APN AMBR) information element indicates the initial subscribed RN-APN-AMBR when the UE establishes a PDN connection or to indicate the new RN-APN-AMBR if it is changed by the network.

In SGW Nodal Test Case, the AMBR information element indicates the APN-AMBR for Bearer Modifications initiated by HSS, MME, UE.

NOTE: The Uplink and Downlink for Extended Rates and Extended-2 Rates are available only when GTPv2 Version is 8.0.0.

Downlink

Enter Downlink AMBR.

Range : 0 to 4294967295 (When GTPv2 Version > 8.0.0)

When GTPv2 Version = 8.0.0 the Downlink AMBR includes Octet 3.

Range: 0 — 255 (Use the conversion wizard for rate/value conversion.)

Default: 1

Tcl Parameter:

LteRelayUeRnAmbrDownlink

Value	Description
0	Subscribed bit rate/reserved
1— 63	Maximum bit rate in 1 kbps increments (1 — 63 kbps)
64— 127	Maximum bit rate in 8 kbps increments (64 — 568 kbps) calculated as (64 kbps + ( (value - 64 kbps) * 8 kbps)).
128— 254	Maximum bit rate in 64 kbps increments (576 — 8,640 kbps) calculated as (576 kbps + (value - 128 kbps) * 64 kbps)).
255	0 kbps

Uplink

Enter Uplink AMBR.

Range : 0 to 4294967295 (When GTPv2 Version > 8.0.0)

When GTPv2 Version = 8.0.0 the Uplink AMBR includes Octet 4.

Range: 0 — 255 (Use the conversion wizard for rate/value conversion.)

Default: 1

Tcl Parameter:

LteRelayUeRnAmbrUplink

Value	Description
0	Subscribed/reserved bit rate
1— 63	Maximum bit rate in 1 kbps increments (1 — 63 kbps)
64— 127	Maximum bit rate in 8 kbps increments (64 — 568 kbps) calculated as (64 kbps + ( (value - 64 kbps) * 8 kbps)).
128— 254	Maximum bit rate in 64 kbps increments (576 — 8,640 kbps) calculated as (576 kbps + (value - 128 kbps) * 64 kbps)).
255	0 kbps

Extended Rates: Downlink

Extended Rates are only applicable when GTPv2 Version = 8.0.0.

Use the checkbox to include octet 5 when a downlink rate larger than 8,640 kbps should be requested. The bit rates are calculated in 100 kbps increments (8,700 — 256,000 kbps) as (8600 kbps + (value * 100 kbps)).

Value	Description
0	Use the value indicated by the APN-AMBR for downlink in octet 3. For all other values, ignore the value indicated by the APN-AMBR for downlink in octet 3 and use the following values:
1— 74	The APN-AMBR is 8600 kbps + ((the binary coded value in 8 bits) * 100 kbps), to giving a range of values from 8700 kbps to 16000 kbps in 100 kbps increments.
75— 186	The APN-AMBR is 16 Mbps + ((the binary coded value in 8 bits - 186) * 1 Mbps), to giving a range of values from 17 Mbps to 128 Mbps in 1 Mbps increments.
187— 250	The APN-AMBR is 128 Mbps + ((the binary coded value in 8 bits - 186) * 2 Mbps), to giving a range of values from 130 Mbps to 256 Mbps in 2 Mbps increments.
The rest...	All other values are interpreted as 250.

Range: 0 — 250 (Use the conversion wizard for rate/value conversion.)

Default: 1

Tcl Parameter:

LteRelayUeRnAmbrDownlinkEx	LteRelayUeRnAmbrDownlinkExEn
LteRelayUeRnAmbrDownlinkEx2	LteRelayUeRnAmbrDownlinkEx2En

Extended Rates: Uplink

Extended Rates are only applicable when GTPv2 Version = 8.0.0.

Use the Extended Rates Uplink checkbox to include octet 6, which is an extension of the APN-AMBR for Uplink in octet 4 and is identical to that of the APN-AMBR for Extended Rates: Downlink.

Range: 0 — 250 (Use the conversion wizard for rate/value conversion.)

Default: 1

Extended-2 Rates: Downlink

Extended Rates are only applicable when GTPv2 Version = 8.0.0.

Use the APN-AMBR for Extended-2 Rates Downlink checkbox to include octet 7.

Range: 0 — 254

Default: 1

Value	Description
0	Use the value indicated by the APN-AMBR for Downlink and APN-AMBR for Extended Downlink octets 3 and 5.
1— 254	The APN-AMBR is (the binary coded value in 8 bits) * 256 Mbps + (the value indicated by the APN-AMBR for Downlink and APN-AMBR for Extended Downlink in octets 3 and 5), giving a range of 256 Mbps to 65280 Mbps
255	0 kbps

Extended-2 Rates: Uplink

Extended Rates are only applicable when GTPv2 Version = 8.0.0.

Use the APN-AMBR for Extended-2 Rates Uplink checkbox to include octet 8. This parameter is an extension of the APN-AMBR for Uplink and APN-AMBR for Extended Uplink in octets 4 and 6. The coding is identical to that of the APN-AMBR for Extended-2 Rates Downlink.

Range: 0 — 254

Default: 1
