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.METHOD FOR IMPROVING SPECTRUM AND WIRELESS SUPERPOSING NETWORKING SYSTEM. In a wireless overlay network location solution for a GSM or UMTS communications network, more efficient spectrum utilization can be provided by BTS synchronization, which may require the distribution of a synchronization signal to all BTS. , or installing a satellite-based sync unit at each location. The present invention provides an architecture wherein Location Measurement Units (LMUs) are installed at some or all BTS sites for the purpose of wireless device location. LMUs are used to measure the synchronization of various uplink and / or downlink signals in the cellular network in support of various location techniques. These LMUs may include a GPS-based synchronization reference module which can be used to synchronize the time bases of all LMUs. To reduce the overall cost of BTS synchronization, the LMU distributes timing signals, including a periodic electrical pulse, as well as time description information, on a serial or other interface, which is available to other nodes for use for Synchronization, Electric pulse format and time description information are modified through hardware and software to adapt to the various forms required by the various types of BTS. For example, BTS with collocated LMUs may receive a synchronization signal with little or no hardware cost. The External Interface Unit (EIU) described in this context can be used to adapt to various BTS hardware formats. For BTS locations not equipped with an LMU, a Synchronization Measurement Unit (TMS) may be used. The TMU has the unique function of providing BTS timing signals in the same formats as LMUs. The time signals provided by the TMUs are synchronized with the signals provided by the LMUs. This time-only TMU has a lower cost than the LMU because it does not support uplink or downlink signal measurement functions. This approach allows a mobile operator to synchronize BTS at a relatively low cost.
