• Theare allowed with HSDPA with the HSDSCHQoSclasses parameter.
• As all PS RABs have to be mapped to the same transport channel, a switch to DCH may thus become necessary for existing RABs if one PS RAB is not allowed to use the HS-DSCH. An active HSPA streaming service may then be reconfigured to DCH during the background RAB setup phase, for example. A new PS streaming RAB can however also trigger a DCH to HS-DSCH channel type switch (see Direct DCH to HS-DSCH switch) if the relevant resource checks are successful and no guard timers are running.
