Abstract
Identificación de vacíos de cobertura usando medidas de traspaso inter-RAT.#Se describen realizaciones de sistemas y técnicas para identificar vacíos de cobertura en una tecnología de acceso por radio (RAT). En algunas realizaciones, un aparato de gestión de red (GR) puede recibir un primer informe, incluyendo una o más medidas tomadas por un primer equipo de usuario (EU), en respuesta a un evento relacionado con un traspaso del primer EU entre una primera tecnología de acceso por radio (RAT) y una segunda RAT diferente de la primera RAT. El aparato de GR puede recibir un segundo informe que incluye una o más medidas tomadas por un segundo EU en respuesta a un evento relacionado con un traspaso del segundo EU entre la primera RAT y una tercera RAT diferente de la primera RAT. El aparato de GR puede identificar un vacío en un área de cobertura de la primera RAT en base, al menos en parte, al primer y segundo informes. Pueden describirse y reivindicarse otras realizaciones.
