1. A method comprising:
- receiving, at a computing device from a terrestrial based transmitter, a digital broadcast multiplex;
locating a physical layer pipe in the received digital broadcast multiplex that includes broadcast protocol signaling information for one or more neighboring satellite multiplexes;
extracting the signaling information for at least one of the one or more neighboring satellite multiplexes from the physical layer pipe; and
storing data related to the extracted signaling information for the at least one of the one or more neighboring satellite multiplexes.

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.
