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.
Claims16
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.
2 more elements
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 transmitter, a digital broadcast multiplex;
- extract signaling information from a physical layer pipe in the digital broadcast multiplex;
- decode 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
- store data related to the network profile information.

- and
- causing the digital broadcast multiplex to be transmitted from the terrestrial 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 transmitter, the digital broadcast multiplex encoded to include one or more physical layer pipes having signaling information including network profile 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;
