Without QOS, the timeslots are assigned based on:
1. MS multislot class
2. Available timeslots on cell
3. BSC/CELL parameter settings
With QOS, the application type AS WELL AS the above criteria are considered. This may not necessarily lead to an improvement in your dl multislot assignmebt, because it depends on the parameter settings. The BSS checks BOTH application and multislot class before assigning resources.
