Description
To provide GPRS with a lower quality radio link while providing a higher throughput when the conditions are good, the CS level should be controlled dynamically.
The following topics are affected:
- Initial CS selection. Currently this is done by configuration. It could also be done by using measurement values provided by the DSP (RSSI and TA) or the MS (C_VALUE, RXQUAL, ...)
- Monitoring ACK/NACK for a DL TBF to adjust the encoding (DL)
- Monitoring packet errors for an UL TBF (poll timeout?)
- Configuration of maximum CS values (UL and DL separately)
- Handle stalls due to enqueued DL RLC/MAC blocks with a CS level that is too high to be received correctly by the MS (TBF termination?)
- Configuration of adaptation parameters
- VTY command to dump per-MS information (overview + detail)
