HSPA+ key technologies for better user experience

Enhanced CELL_FACH

Reduce the latency of user and control plane in the CELL_FACH, CELL_PCH

and URA_PCH state by higher data peak rate

Reduce state transition delay from CELL_FACH, CELL_PCH and URA_PCH

state to CELL_DCH state

Reduce call setup delay and HTTP response time

CPC (Continuous Packet Connectivity)

DTX_DRX save power consumption of terminal so that more users can stay inCELL_DCH state and spend less time in reactivation with no need of state transfer.

L2 Enhancement

With flexible RLC PDU size, small size will be configured in poor

coverage area in order to be sent successfully.
