Abstract

"REDE TELEFôNICA MóVEL CELULAR E MéTODO PARAOPERAR A MESMA". Quando um móvel é comutado em umsistema celular, pesquisa-se primeiro pela melhor célula a que sepossa conectar e em seguida tenta enviar uma mensagem para amelhor célula encontrada. Em sistemas celulares CDMA, aprobabilidade de uma mensagem de RACH de móvel ser recebidacom êxito por uma célula depende fortemente da sua potência detransmissão. Infelizmente, ter todos os móveis transmitindo àmáxima potência possível é em muitas circunstâncias não apenasdesnecessário, mas também inaceitável, devido à resultanteinterferência entre células gerada. é revelada uma rede telefônicamóvel celular onde uma estação móvel solicita serviços em dadosmodulados em um canal de acesso aleatório (RACH) comum emum formato associado a uma primeira célula na qual a estaçãomóvel está localizada. Estações base em células adjacentes àprimeira célula são configuradas para demodular a rajada demensagem de RACH que tenham o formato associado à primeiracélula, e para passar os dados demodulados para um controladorde rede de rádio (RNC) Isto permite que a potência médianecessária para uma transmissão de RACH com êxito sejareduzida.
