Title (EN) METHOD AND APPARATUS FOR PERFORMING A CANDIDATE FREQUENCY SEARCH IN A WIRELESS COMMUNICATION SYSTEM
(FR) PROCEDE ET APPAREIL DE RECHERCHE D'UNE FREQUENCE CANDIDATE DANS UN SYSTEME DE TELECOMMUNICATIONS SANS FIL
Abstract: front page image
(EN)A method and apparatus for decreasing the probability of dropping a call during a hard handoff procedure in a wireless communication system (FIG. 1). The two primary functions of the candidature frequency (CF) search method and apparatus of the present invention are to detect the strong pilots (908-916) on a candidate frequency in the area of the mobile station and to maintain adequate service quality during the CF search (FIG. 8).
(FR)L'invention porte sur un procédé et un appareil réduisant la probabilité d'interruption d'une communication pendant une procédure difficile de transfert dans un système de télécommunications sans fil. Les deux fonctions primaires du procédé et de l'appareil de recherche d'une fréquence candidate (CF) de ladite invention, consistent à détecter les pilotes forts (908-916) d'une fréquence candidate dans l'aire de la station mobile et maintenir une qualité adéquate de services pendant la recherche de la fréquence candidate.
