  • Patent number: 6292664
    Abstract: 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.
