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.
Claims20
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.
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to:
- receive, from a terrestrial based transmitter, a digital broadcast multiplex;
- locate a physical layer pipe in the received digital broadcast multiplex that includes broadcast protocol signaling information for one or more neighboring satellite multiplexes;
- extract the signaling information for at least one of the one or more neighboring satellite multiplexes from the physical layer pipe;
- and
- store data related to the extracted signaling information for the at least one of the one or more neighboring satellite multiplexes.
A method comprising:
- encoding a digital broadcast multiplex configured for transmission from a terrestrial based transmitter, the digital broadcast multiplex encoded to include one or more physical layer pipes having broadcast protocol signaling information for one or more neighboring satellite multiplexes;
- and
- causing the encoded digital broadcast multiplex to be transmitted from the terrestrial based transmitter.
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to:
- encode a digital broadcast multiplex configured for transmission from a terrestrial based transmitter, the digital broadcast multiplex encoded to include one or more physical layer pipes having broadcast protocol signaling information for one or more neighboring satellite multiplexes;
- and
- cause the encoded digital broadcast multiplex to be transmitted from the terrestrial based transmitter.
