Abstract

<B>MéTODO E APARATO PARA AJUSTE ADAPTáVEL DE FORçA DE TRáFEGO INICIAL<D> Um método e aparato que permite estações base a adaptivamente ajustar níveis de força iniciais em canais de tráfego de conexão de transmissão (por exemplo, estação base para unidade móvel) baseado em uma medida de interferência, onde a medida de interferência é a diferença entre o piloto transmitido de estação base E~ c~ /I~ o~ e o piloto recebido de unidade móvel E~ c~ /I~ o~ . A medida de interferência indica quanta interferência está presente oriundas de outras estações base na localidade de unidade móvel, ruído de receptor móvel e outras fontes similares. Qualidade de chamada e capacidade de sistema são otimizados uma vez que o nível de força inicial é ajustado de acordo com o ambiente interferente. O método da invenção implementa o ajuste adaptável pela extração de piloto recebido de unidade móvel E~ c~ /I~ o~ da mensagem de acesso transmitida pela unidade móvel. A medida de interferência é então determinada e usada pela estação base para ajustar o nível de força inicial no canal de tráfego de conexão de transmissão.
