The Serving Gateway needs the Bearer QOS information for IP packet Uplink and Downlink. The Serving Gateway ensures that the granted QOS does not exceed the Authorized QoS per IP flow. The authorized bit rate/sec is defined separately for Uplink and Downlink packet flow. Bearer QoS is also defined for bearer initiated modifications (MME and UE).
| Summary/Individual |
You can define one QOS for all bearers or a different QOS for every bearer per subscriber.
When you select Individual, a Bearer sub-tab is displayed for each Maximum Bearer per subscriber (selected on the Mobile Subscriber pane on the Test Configuration tab). For example, if Maximum Bearers Per Subscriber is 3, the bearer QoS tabs displayed are Default, B2, and B3. |
|||||
| Class Identifier |
The Class ID in the Bearer QOS applies to the Uplink (UL) and Downlink (DL) IP flows. LTE test cases provide you with the ability to configure various QCI. You can choose to use the same QoS Class ID for all IP contexts or you can define different Class IDs for each context. Range: 0 — 255
Tcl Parameter: TgtGtp2QosClassId_1
|
|||||
| ARP Priority Level |
Use the ARP (Priority of Allocation and Retention) 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).
Range: 0 - 15 Default: 1 Tcl Parameter: TgtGtp2QosArpValue_1 |
|||||
| Set Bit Rates |
The Set Bit Rates checkbox is available only when Class Identifier value is 0 or between 10 and 255. Range : 0 to 255 Select the Set Bit Rates checkbox to enter Maximum Bit Rates and Guaranteed Bit Rates values for UL and DL traffic. Tcl Parameter: TgtGtp2QosBrEn_1 |
|||||
| Pre-emption Capability |
Selecting this checkbox indicates that the bearer may preempt other bearers with a lower ARP value when resource limitations are reached. |
|||||
| Pre-emption Vulnerability |
Selecting this checkbox indicates that a bearer is vulnerable to being dropped when resource limitations have been reached and there is a bearer with a higher ARP value in service. Tcl Parameter: TgtGtp2QosArpPreemptVulnEn_1 |
|||||
| Maximum Bit Rates and Guaranteed Bit Rates |
Define the IP flow Maximum Bit Rates and Guaranteed Bit Rates for UL and DL traffic. Range: 0 - 10000000000 Default: 1
