Abstract

"PROCESSO PARA EXECUTAR TRANSFERêNCIA DE CONTROLE EM UM SISTEMA PARA RADIOCOMUNICAçãO, E, SISTEMAS PARA RADIOCOMUNICAçãO, E PARA AJUSTE DE UM CONJUNTO ATIVO DE FONTES QUE TRANSMITEM SINAIS PARA UM RECEPTOR PARTICULAR". Sistema para radiocomunicação tendo capacidades de transferência de controle suave melhoradas são descritos. Durante transferência de controle suave uma estação móvel pode ter várias fontes de transmissão (membros de conjunto ativos) a provendo com substancialmente a mesma informação. Estações móveis que não estão se movendo podem não requerer tantas fontes para prover qualidade de sinal recebido adequada. Portanto, estações móveis que não estão se movendo são identificadas usando técnicas e membros do conjunto ativo são comparadas com um limiar mais alto para remover ramais mais fracos mais rapidamente do que quando usando um limiar que é aplicado a estações móveis que estão em movimento."PROCESS TO PERFORM CONTROL TRANSFER IN A SYSTEM FOR RADIOCOMMUNICATION, AND, SYSTEMS FOR RADIOCOMMUNICATION, AND FOR ADJUSTING AN ACTIVE SET OF SOURCES THAT TRANSMIT SIGNS TO A PRIVATE RECEIVER". Radio communication systems having improved smooth control transfer capabilities are described. During smooth control transfer a mobile station can have several transmission sources (active cluster members) providing it with substantially the same information. Mobile stations that are not moving may not require as many sources to provide adequate received signal quality. Therefore, mobile stations that are not moving are identified using techniques and active set members are compared with a higher threshold to remove weaker extensions more quickly than when using a threshold that is applied to mobile stations that are in motion.
