Le transfert progressif est largement adopté dans les systèmes d'accès multiple par répartition en code (CDMA) en raison de ses nombreux avantages résultant principalement de la diversité des sites. Cependant, dans la liaison aller, d'autres interférences cellulaires peuvent être augmentées par un transfert progressif, réduisant ainsi la capacité du système. Dans les futurs systèmes mobiles, il est très important de prévoir une capacité de liaison aller suffisante étant donné que la charge de la liaison aller est bien supérieure à la charge de la liaison retour dans les services multimédias mobiles tels que l'accès à Internet. Dans cet article, nous considérons une stratégie de transfert combinée dans laquelle les services vocaux sont fournis avec un transfert progressif tandis que les services de données sont pris en charge avec un transfert dur. Nous analysons l'effet de la méthode de transfert sur les performances de la liaison aller. Les mesures de performances que nous utilisons sont la probabilité de panne du rapport énergie binaire/densité de bruit et la capacité basée sur la probabilité de panne. En conséquence, nous montrons que le transfert combiné est très utile dans les réseaux cellulaires CDMA prenant en charge simultanément les services voix et données.

Abstract: The soft handoff is widely adopted in code division multiple access (CDMA) systems for its many advantages mainly resulting from site diversity. However, in the forward link, other cell interference can be increased by soft handoff, decreasing system capacity. In future mobile systems, provision for the sufficient forward link capacity is very important since the forward link load is much higher than the reverse link load in mobile multimedia services such as Internet access. In this paper, we consider a combined handoff strategy in which voice services are provided with soft handoff whereas data services are supported with hard handoff. We analyze the effect of handoff method on the forward link performance. The performance measures we use are the outage probability of the bit energy to noise density ratio and the capacity based on the outage probability. As a result, we show that the combined handoff is very useful in CDMA cellular networks supporting both voice and data services simultaneously.
