Abstract

Methods and apparatus for RF handoff in a multi-frequency network. A method includes generating seamless and partially seamless handoff tables for multiplexes carried in a current LOI, wherein the seamless and partially seamless handoff tables comprise neighboring RF channels carrying one or more of the multiplexes in the current LOI, detecting a handoff event initiated by acquisition failures on a current RF, selecting a selected RF channel from the seamless and partially seamless handoff tables, and performing a handoff to the selected RF channel. An apparatus includes processing logic configured to generate the seamless and partially seamless handoff tables, detect a handoff event initiated by acquisition failures on a current RF, and select a selected RF channel from the seamless and partially seamless handoff tables. The apparatus also includes channel switch logic configured to perform a handoff to the selected RF channel.
