摘要： A system and method in a wireless communications environment maximizes voice quality in low capacity situations. A Mobile services Switching Centre (MSC) that is associated with a base station of a cell is capable of assigning speech calls of mobile terminals to either a full-rate (FR) or a half-rate (HR) channel. The FR channels provide better transmitted voice quality but consume twice the bandwidth (two time slots versus only one for HR channels). When occupied cell capacity is low, an MSC assigns connections to FR channels. After occupied cell capacity reaches a predetermined threshold value, the MSC assigns connections to HR channels whenever possible. Also, handover procedures can reclaim available capacity by switching a connection from a FR to a HR channel. The superior voice quality of the FR channels are therefore provided to mobile terminal users more often.

摘要： A method for determining numbers of gear steps N for a gearbox in a motor vehicle. The vehicle has an engine connected to drive the gearbox. The numbers of gear steps N is the number of downshifts or the number of upshifts which the gearbox effects at an upshift point or a downshift point. A downshift point represents a first engine speed at which the gearbox effects a downshift. An upshift point represents a second engine speed at which the gearbox effects an upshift. The numbers of gear steps N are determined on the basis of a predicted acceleration a for the motor vehicle during a time period T. The invention relates also to a system, a motor vehicle, a computer program and a computer program product thereof for performing the method.
