Abstract

"PROCESSO PARA LOCALIZAçãO DE ESTAçãO MóVEL EM CONEXãO COM UMA TRANSFERêNCIA DE CONTROLE POTENCIAL, E, REDE DE COMUNICAçõES CELULARES". Uma rede de comunicações celulares incluem diversas células (100) cujas estações base possuem ambas capacidades de antena de setor (104) e antena inteligente (110). Enquanto envolvida em uma chamada (200), as medições de intensidade de sinal (202, 204) de enlace inferior da estação móvel (114) são feitas em seu próprio canal de tráfego de serviço e canais de controle das células vizinhas. Estas medições são então ajustadas (210) por um ou mais fatores que consideram as diferenças operacionais e físicas entre antena de setor e antena inteligente. Por exemplo, as medições de intensidade de sinal podem ser apropriadamente ajustadas por diferenças medidas no ganho entre a antena inteligente e a antena de setor, valores recuo de potência de saída associados a antena inteligente e antena de setor de suporte dos canais de tráfego em comparação com os canais de controle, e atenuação de controle de potência aplicada aos canais de tráfego. As medições de intensidade de sinal de enlace inferior ajustadas resultantes podem então ser comparadas com cada outra (como deslocamento por qualquer valor de histerese imposto) para localizar mais precisamente a estação móvel e definir uniformemente, previsivelmente e precisamente quando é apropriado autorizar uma transferência de controle.
