Patent CA-2319439-A1 (CA)
Inventor: WESTROOS ANDERS KJELL
IPC: H04L1/00
Filed: 1999-01-29
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 (110) of a cell (100) is capable of assigning (220) speech calls of mobile terminals (120-180) to either a full-rate (FR)(240) or a half-rate (250) (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 (210) is low, an MSC assigns connections to FR (240) channels. After occupied cell capacity (210) reaches a predetermined threshold (230) value, the MSC assigns connections to HR (250) 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.

Abstract: Selon l'invention, un module de compensation de dispersion est couplé à une fibre optique d'émission. Ce module de compensation de dispersion comporte des segments de fibre optique présentant différentes longueurs, dont certains présentent une dispersion positive tandis que d'autre présentent une dispersion négative. Des segments choisis de fibre optique sont couplés les uns aux autres de façon à produire une dispersion nette voulue et à décaler la dispersion associée à la fibre optique d'émission. De cette façon, au lieu d'utiliser un seul segment de fibre à dispersion compensée pour chaque intervalle, on peut utiliser le même module de compensation de dispersion pour des intervalles présentant différentes longueurs et différents types de fibres, en connectant simplement les segments appropriés de fibres dans le module.
