QoS Rules

The Number of Rules Set define the maximum number of the Rules Set for an IP Connectivity Access Network (IP-CAN) bearer or service flow.

Range: 1 - 10

Default: 1

Tcl Parameter: GxcSrvNumRulesSet

The number of Rules Set tab depends on the Number of Rules Set you select.

Enter the length of time to Wait in seconds between execution of Rules Action (instal or remove QoS Rules).

Tcl Parameter: QxcSrvRuleInterval_1

Type: True/False

QoS Rules

The QOS Rules parameters are available only when the Number of Rule Set is > 0 and Number of Rules (QoS) is > 0. The QoS rules define the authorized QoS traffic class for an IP connectivity Access Network (IP-CAN) bearer or service flow.

The Number of Rules define the maximum number of QOS authorized for an IP Connectivity Access Network (IP-CAN) bearer or service flow.

Valid Options: 1 - 12

Tcl Parameter: GxcSrvNumQr_0

Rule n

The Rule Name defines a name for QOS rule and uniquely identifies a QOS traffic rule within the GXc. For example, the default Rule Name for Rule Set 1 of QoS Rule 1 is Rule Name 1_1, Rule Name for Rule Set 2 of QoS Rule 1 is Rule Name 2_1, and so on.

Tcl Parameter: QxcSrvQrRuleName_1_1

Use the dropdown list to indicate the rules Action (instal, remove, or modify QoS Rules) to execute.

Tcl Parameter: QxcSrvQrAction_1_1

Type: True/False

The QOS Class ID defines the maximum authorized traffic class for the IP-CAN bearer or service flow  

Select the QoS Class ID checkbox, enter the required QOS Class ID and define the associated maximum bandwidth for uplink and downlink IP packets.  

Range: 0 - 255

Tcl Parameter:

The Precedence parameter defines the precedence of a QOS rule in case of overlapping QOS rules. A QOS rule with a lower value in the Precedence parameter takes priority over a QOS rule with a higher Precedence value.

The Precedence parameter is also used to indicate the evaluation precedence of the TFT packet filters. Select the Precedence checkbox and enter the precedence value.

Value: True/False

Options: 1 - 4294967295

Default: 1

Tcl Parameter:

Select the checkbox to enable and enter the maximum bandwidth for Uplink and Downlink values.

Tcl Parameter: GxcSrvQrMaxBwEn_1_1

Type: True/False

• Uplink defines the maximum bit rate in kilo bits per second allowed for the Uplink IP packets.

Tcl Parameter: GxcSrvQrMaxUplink_1_1

Range: 1 — 4294967295

• Downlink defines the maximum bit rate in kilo bits per second allowed for the Downlink IP packets.

Tcl Parameter: SrvQrMaxDownlink_1_1

Range: 1 — 4294967295

Select the checkbox to enable and enter the Guaranteed Uplink and Downlink values.

Tcl Parameter: GxcSrvQrGuaranteedBwEn_1_1

Type: True/False

• The Uplink defines the Guaranteed bit rate in kilo bits per second allowed for the Uplink IP packets.

     Tcl Parameter: GxcSrvQrGuaranteedUplink_1_1

Range: 1 - 4294967295

Default: 300

• The Downlink defines the Guaranteed bit rate in kilo bits per second allowed for the Downlinklink IP packets

Tcl Parameter: GxcSrvQrGuaranteedDownlink_1_1

Range: 1 - 4294967295

Default: 300

Use the ARP (Allocation and Retention Priority) to determine the relative priority level during admission and congestion processes.

The primary purpose of ARP is to decide whether a bearer establishment/modification request is accepted or needs to be rejected in case of resource limitations (typically available radio capacity in case of GBR bearers). In addition, the ARP is also used (e.g. by the eNodeB) to decide which bearer(s) to drop during exceptional resource limitations (e.g. at handover). Once successfully established, a bearer's ARP does not have any impact on the bearer level packet forwarding treatment (e.g. scheduling and rate control).

Tcl Parameter: GxcSrvQrArpE_1_1

Type: True/False

• ARP Value

Tcl Parameter: GxcSrvQrArpValue_1_1

Range: 1 - 15

Default: None

• Pre-emption Capability: Select the checkbox to enable

Tcl Parameter: GxcSrvQrArpPreemptCapEn_1_1

Type: True/False

• Pre-emption Vulnerability: Select the checkbox to enable

Tcl Parameter: GxcSrvQrArpPreemptVulnEn_1_1

Type: True/False

Select the Number of Filters from the dropdown list. The number of Packet Filter rows depend on the value selected in the Number of Filters dropdown list.

Tcl Parameter: GxcSrvQrNumFilters_1_1

Range: 1 - 16

Default 1

• Description: Indicates whether the IP address is that of the traffic permitted in or traffic sent out.

• Dest IP: Depending on the description:

• • Enter the IP Address from which the traffic is permitted in, OR

  • Enter the IP address from where the traffic is sent to the destination IP Address.

• IP Ext: Enter the IP extension from which the traffic is permitted in, as per the description.

• Ip Type: Select the type as IPv4 or IPv6 from the dropdown list.

Select the Tunnel Information checkbox to enable the Tunnel Filter,  Header Length and enter the header length.

The Tunnel information is used to identify the tunnel used for forwarding service data flow identified in a QoS rule (between a Mobile Access Gateway (MAG/S-GW) and Local Mobility Anchor (LMA/P-GW)).

Tcl Parameters:

The Tunnel Filter rule is optional and allows you to define the traffic filter (uplink/downlink) for the tunnel. The terms Filter, User IP to Destination IP, and Destination IP to User IP refer to the Tunnel IP address which applies QOS Rules on the traffic traversing it.

• Description: Indicates whether the IP Address if from which the traffic is permitted in or out.

• Dest IP: Depending on the description:

• • Enter the IP Address from which the traffic is permitted in, OR

  • Enter the IP address from where the traffic is sent to the destination IP Address.

• IP Ext: Enter the IP extension from which the traffic is permitted in or out, as per the description.
