1. A method comprising:
- receiving, at a computing device from a terrestrial transmitter, a digital broadcast multiplex;
extracting signaling information from a physical layer pipe in the digital broadcast multiplex;
decoding network profile information in the signaling information, the network profile information indicating, when a first value, that one or more neighboring satellites transmitting one or more neighboring satellite multiplexes and one or more neighboring terrestrial transmitters transmitting one or more neighboring terrestrial multiplexes form a single-frequency network, and the network profile information indicating, when a second value, that the one or more neighboring satellites and the one or more neighboring terrestrial transmitters form a multi-frequency network; and
storing data related to the network profile information.

Abstract
A hybrid satellite/terrestrial wireless network having a plurality of terrestrial cells and satellite coverage areas is disclosed. A multiplex transmitted in a terrestrial cell may include signaling information for neighboring terrestrial cells and neighboring satellite coverage areas. The signaling information may include indicators identifying different profiles for the hybrid satellite/terrestrial network, and include other information enabling handover from the terrestrial cell multiplex to one of the neighboring terrestrial or satellite multiplexes.
