The intra-cell call hand-over technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining a standby radio traffic channel upon which to hand over a call. Communication between the base station and subscriber terminal is carried out on an inband or associated signalling channel for the selection of the standby traffic channel. The standby radio channel is the channel, which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal. The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service. This subset is comprised of those channels having little interference as measured by the base station. The call hand-over technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.
La méthode de transfert d'appels intracellulaire de la présente invention est caractérisée par l'utilisation d'une information sur les canaux obtenue de la station de base et d'un terminal d'abonné pour choisir le canal radio sur lequel l'appel doit être transféré. La communication entre la station de base et le terminal de l'abonné se fait sur un canal de bande interne ou un canal de signalisation connexe pour choisir le canal d'attente. Parmi les canaux examinés par le terminal de l'abonné, le canal choisi est celui qui est le moins parasité d'après le terminal de l'abonné. L'ensemble des canaux examinés par le terminal de l'abonné est un sous-ensemble de l'ensemble des canaux affectés au service. Ce sous-ensemble comprend les canaux peu parasités d'après la station de base. La méthode de l'invention est telle que les appels sont transférés sur des canaux peu parasités aux points de vue de la station de base et du terminal de l'abonné.
