Abstract

Patente de Invenção: MéTODO E EQUIPAMENTO PARA EFETUAR REPASSE EM UM SISTEMA CDMA ATRAVéS DO USO DE REPETIDORAS. Um método e um equipamento para prover repasse entre dois sistemas de comunicação. Os sistemas podem ser sistemas CDMA operando em freq³ências diferentes ou sistemas empregando diferentes tecnologias. No primeiro sistema, uma estação base (4) está configurada para prover comunicações para dois ou mais setores, com pelo menos um setor designado para uma correspondente repetidora (8) a qual provê cobertura que se sobrepõe àquela de ambos os sistemas. A medida que a estação remota (6) se move para a área de cobertura da repetidora (8), o sinal piloto da repetidora (8) é identificado, medido e enviado para o primeiro sistema. Caso o sinal piloto medido esteja acima de um limite de adição predeterminado, a repetidora (8) é adicionada ao conjunto ativo da estação remota. O primeiro sistema pode repassar a estação remota (6) para o segundo sistema: (1) quando do início de um repasse suave pela estação base do primeiro sistema; (2) caso a força do sinal piloto da repetidora (8), tal como medida pela estação remota (6), supera um limite de repasse predeterminado; (3) caso a estação base (4) do primeiro sistema seja retirada do conjunto ativo da estação remota (6); (4) caso a repetidora do primeiro sistema seja retirada do conjunto ativo da estação remota (6); ou (5) caso a estação base (4) e a repetidora (8) do primeiro sistema sejam retiradas do conjunto ativo da estação remota (6).Invention Patent: METHOD AND EQUIPMENT FOR TRANSFERING A CDMA SYSTEM THROUGH THE USE OF REPEATERS. A method and equipment to provide transfer between two communication systems. The systems can be CDMA systems operating at different frequencies or systems using different technologies. In the first system, a base station (4) is configured to provide communications for two or more sectors, with at least one sector designated for a corresponding repeater (8) which provides coverage that overlaps that of both systems. As the remote station (6) moves to the repeater coverage area (8), the pilot signal from the repeater (8) is identified, measured and sent to the first system. If the measured pilot signal is above a predetermined addition limit, the repeater (8) is added to the remote station's active set. The first system can transfer the remote station (6) to the second system: (1) when a smooth transfer through the base station of the first system begins; (2) if the repeater pilot signal strength (8), as measured by the remote station (6), exceeds a predetermined pass-through limit; (3) if the base station (4) of the first system is removed from the active set of the remote station (6); (4) if the repeater of the first system is removed from the active set of the remote station (6); or (5) if the base station (4) and the repeater (8) of the first system are removed from the active set of the remote station (6).
