Abstract

"PROCESSO E SISTEMA PARA REALIZAR UMA TRANSFERêNCIA DE CONTROLE INTERCELULAR EM UM SISTEMA DE COMUNICAçàO MóVEL, E, ESTAçãO BASE DE RáDIO" Processo (300) e sistema (200, 400) são divulgados para fazer transferências de controle intercelulares pra uma célula de uma estação base (BS2, BS3), incluindo um feixe de antenas bidirecionais (401, 403). O algoritmo de transferência de controle (309) inclui levar em conta a direção de ligação, ascendente de medições de chegada (305) em pelo menos uma estação base alvo candidata, feita em sinais do terminal de rádio móvel (203, 417) para sua estação base (BSI) e diretamente após a transferência de controle, usando um lobo estreito direcional do feixe de antena. O lobo estreito pode ser usado imediatamente após a transferência de controle (313) nas estações base de rádio (BS2, BS3) que têm feixes de antenas (401, 413), através da inclusão da direção (de informação de chegada), para o terminal de rádio móvel (203, 417) na ordem de transferência de controle (311) paa a estação base alvo. Também são divulgados um método e um sistema para medição da interferência da ligação ascendente nos canais de tráfego de lobos estreitos inativos (307) e usando essa informação, quando da seleção em transferência de controle de uma estação base alvo e de um canal de tráfego (309).
