GPRS QoS Mapping Table
Smartphone and Pocket PC internally convert the 3G GPRS QoS settings to 2G GSM GPRS QoS settings by using the following mapping table. It is listed in 3GPP TS 23.107 V3.5.0 (2000-12).
| GSM GPRS used QoS Name |
Value |
WAP Provisioning Defined 3GPP QoS Value |
Name |
|---|---|---|---|
| Delay class | 1 | Conversational | Traffic class |
| 1 | Streaming | Traffic class | |
| 1 | Interactive | Traffic class | |
| 1 | Traffic handling priority | ||
| 2 | Interactive | Traffic class | |
| 2 | Traffic handling priority | ||
| 3 | Interactive | Traffic class | |
| 3 | Traffic handling priority | ||
| 4 | Background | Traffic class | |
| Reliability class | 2 | <= 10-5 | SDU error ratio |
| 3 | 10-5 < x <= 5*10-4 | SDU error ratio | |
| 4 | > 5*10-4 | SDU error ratio | |
| <= 2*10-4 | Residual bit error ratio | ||
| 5 | > 5*10-4 | SDU error ratio | |
| > 2*10-4 | Residual bit error ratio | ||
| Peak throughput class | 1 | < 16 | Maximum bit rate (Kbps) |
| 2 | 16 <= x < 32 | ||
| 3 | 32 <= x < 64 | ||
| 4 | 64 <= x < 128 | ||
| 5 | 128 <= x < 25 | ||
| 6 | 256 <= x < 512 | ||
| 7 | 512 <= x < 1024 | ||
| 8 | 1024 <= x < 2048 | ||
| 9 | >= 2048 | ||
| 9 | >= 2048 | ||
| Precedence class | 1 | 1 | Allocation/retention priority |
| 2 | 2 | ||
| 3 | 3 | ||
| Mean throughput class | Always set to 31 | - | |
| Reordering required (information in the SGSN and the GGSN PDP contexts) | yes | yes | Delivery order |
| no | no |
If, by chance, a mobile operator sends a WAP provisioning XML file version that predates August 2000, the preceding mapping table is not used. The GPRS QoS settings in that specification are GSM 2G GPRS QoS settings, which Smartphone and Pocket PC support. In this case, it is a one-to-one mapping between WAP QoS and GPRS Smartphone-supported QoS settings. These settings are listed in the following mapping table.
| GSM 2G GPRS QoS settings | Old WAP Provisioning QoS parms in NAPDEF | Device converts to CM_GPRSEntries Configuration Service Provider parms |
|---|---|---|
| Precedence class | SERVICE-PRECEDENCE | GPRSInfoQOSPrecedenceClasss |
| Delay class | DELAY | GPRSInfoQOSDelayClasss |
| Reliability class | RELIABILITY-CLASS | GPRSInfoQOSReliabilityClasss |
| Peak throughput class | THROUGHPUT | GPRSInfoQOSPeakClasss |
| Mean throughput class | MEAN-THROUGHPUT | GPRSInfoQOSMeanClasss |
