The invention relates to a handover method and a method for selecting the base station for connecting a multimode terminal (PP/MS) in a mobile communication system which consists of at least one first base station (BTS) and at least one second base station (FRP) controlled by a MSC, and multimode terminals (PP/MS). The handover method comprises the steps of recognizing the poor radio connection between the serving second base station (RFP) and the multimode terminal (PP/MS), selecting one of the first base stations (BTS) as the target cell for handover on the basis of the measurements carried out in the multimode terminal (PP/MS), and performing the handover. It is characteristic of the handover method according to the invention that a cell description is transmitted to the multimode terminal (PP/MS) via the second base station (RFP), the cell description including information about the frequency of at least one first base station (BTS), and measuring base station signal in the multimode terminal (PP/MS) at said frequencies, when the ongoing radio connection has been recognized to be poor.
L'invention concerne un procédé de transfert, ainsi qu'un procédé de sélection d'une station de base permettant de connecter un terminal multimode (PP/MS) à un système de communication mobile, constitué d'au moins une première station de base (BTS), d'au moins une seconde station de base (RFP), ces stations étant commandées par un central du service mobile (MSC), et de terminaux multimode (PP/MS). Ce procédé de transfert comprend les étapes consistant: à identifier une mauvaise connexion radio entre la seconde station de base de desserte (RFP), et le terminal multimode (PP/MS); à choisir l'une des premières stations de base (BTS) en tant que cellule cible pour le transfert, en fonction des mesures effectuées dans ledit terminal multimode (PP/MS); et enfin à réaliser ce transfert. Selon cette invention, ce procédé de transfert se caractérise par la transmission d'une description de la cellule au terminal multimode (PP/MS), par l'intermédiaire de la seconde station de base (RFP), cette description de la cellule comprenant des informations relatives à la fréquence d'au moins une des premières stations de base (BTS). Ce procédé se caractérise également par la mesure du signal de la station de base dans le terminal multimode (PP/MS), aux fréquences susmentionnées, lorsque l'on estime que la connexion radio en cours est mauvaise.
