Abstract

MéTODO PARA APERFEIçOAMENTO DE ESPECTRO E SISTEMA DE LOCALIZAçãO SEM-FIO DE SUPERPOSIçAO DE REDES. Em uma solução de localização sem-fio de sobreposição de redes para unia rede de comunicações GSM ou UMTS, pode proporcionar-se uma utilização de espectro mais eficiente pela sincronização dos BTS, que podem requerer a distribuição de um sinal de sincronização para todos os BTS, ou instalação de uma unidade de sincronização baseada em satélite em cada local. A presente invenção proporciona uma arquitetura em que Unidades de Medição de Local (LMUs) são instaladas em alguns ou todos os locais de BTS para-o propósito de localização de dispositivos sem-fio. Os LMU-são usados para medir a sincronização de vários sinais de conexão ascendente e/ou conexão descendente na rede celular, no suporte de várias técnicas de localização. Estas LMU podem incluir um módulo de referência de sincronização baseado em GPS, que pode ser usado para sincronizar as bases de tempo de todas as LMU. Para reduzir o custo global de sincronização de BTS, a LMU distribui sinais de temporização, incluindo um pulso elétrico periódico, bem como informação de descrição de tempo, em uma interface em série ou outra, que se encontra disponível para outros nós para o uso para sincronização, O formato do pulso elétrico e informação de descrição de tempo são modificados através de hardware e software para adaptação às várias formás requeridas pelos vários tipos de BTS. Por exemplo, os BTS com LMUs colocalizadas podem receber um sinal de sincronização com pouco ou nenhum custo de hardware. A Unidade de Interface Externa (EIU) descrita neste contexto pode ser usada para adaptação a vários formatos de hardware de BTS. Para locais de BTS não equipados com uma LMU, poderá ser utilizada uma Unidade de Medição de Sincronização (TMS) . A TMU tem a função única de proporcionar sinais de temporização de BTS nos mesmos formatos que são proporcionados pelas LMU. Os sinais de tempo proporcionados pelas TMU são sincronos com os sinais proporcionados pelas LMU. Esta TMU somente de temporização tem um custo mais baixo do que a LMU porque ela não suporta as funções de medição de sinal de conexão ascendente ou conexão descendente. Esta abordagem permite a um operador de celular sincronizar os BTS a um custo relativamente baixo.
