Abstract

Un sistema para transferencia intercelular entre sistemas para un sistema de comunicaciones inalámbricas soporta transmisión descendente y transmisión ascendente del equipo del usuario (UE) para diferentes tecnologías de acceso por radio, incluyendo sistemas síncronos y asíncronos. Los fallos de conexión de latencia y transferencia intercelular se reducen mediante un nodo de acceso (NodeB) que radio difunde la información acerca de los sistemas contiguos (blancos) cuando la capacidad de recepción del UE (RX) es tanto hacia dentro como hacia fuera del margen de recepción del blanco. Una cadena RX individual es suficiente, aunque una transición entre una red de área amplia inalámbrica (WWAN) hacia una red de área local inalámbrica (WLAN) se puede beneficiar ventajosamente de la operación simultánea en dos cadenas Rx. La lista optimizada de los sistemas RAT contiguos (blancos) se radiodifunde desde la red, incluyendo los parámetros de medición e instrucciones de reporte. Con esto, el reporte conducido del UE reduce al mínimo las latencias. El UE reporta las búsquedas de otros sistemas a la red sólo si es necesario para una transferencia intercelular. Además, las peticiones de transferencia intercelular se pueden empaquetar con la información de medición de otros sistemas, si necesario, para eficacias adicionales.
