摘要： Aspects of the invention are directed to service discovery in a digital broadcast network. A service discovery descriptor, which may be electronic service guide-provider and cell specific, provides mapping between a service identifier, a logical channel identifier, and a physical channel, which may be characterized by a frame identifier and a slot identifier, that is, each physical channel may have one or more slots within one or more frames. A neighboring service discovery descriptor provides mapping for the service available within neighboring cells. Aspects of the invention are directed to an encapsulation protocol that encapsulates variable length data, including, but not limited to, the service discovery descriptor and the neighboring service discovery descriptor, into fixed length data stream packets.

摘要： Embodiments are directed to defining hierarchical digital broadcast transport streams as separate cells, which reduces the signaling in OSI layer 1, and removing use of sub-cells so that the coverage area of a transposer may be treated as a cell. In accordance with at least one embodiment, each hierarchical DVB-H stream (i.e., the HP stream and the LP stream) has its own separate dedicated “current signal” frame. This allows the streams to be independent of each other (even to belong to different networks). Furthermore, in accordance with the hierarchical signal arrangement, a cell can be uniquely identified by its network_id and cell_id. In accordance with at least one embodiment, frequency may be used as an additional identifier thereby allowing a first cell to be transposed to a sub-cell.

摘要翻译： 实施例旨在将分层数字广播传输流定义为单独的小区，其减少OSI层1中的信令，并且去除子小区的使用，使得转移器的覆盖区域可被视为小区。 根据至少一个实施例，每个分级DVB-H流（即，HP流和LP流）具有其自己的独立专用“当前信号”帧。 这允许流彼此独立（甚至属于不同的网络）。 此外，根据分层信号布置，可以通过其network_id和cell_id唯一地识别小区。 根据至少一个实施例，频率可以用作附加标识符，从而允许第一小区被转置到子小区。

摘要： Aspects of the invention are directed to service and channel discovery in a digital broadcast network. A pilot synchronization symbol, which has known characteristics, is included as a first symbol of digital broadcast frames. The pilot symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. In another aspect of the invention, at least two pilot symbols may be defined and used at the beginning of each frame. The at least two pilot symbols P1 and P2 may enable fast channel search and service discovery within the frame. Signaling may be realized as a combination of L1 and L2 signaling.

摘要： A computer-readable medium, device and system for responding to a request for a geographically-based service are provided. A request for a geographically-based service is received. The received request indicates that a geographical position of a target node and a radius associated with a maximum distance from the geographical position is requested. A requesting service message is formatted that is associated with a higher-layer protocol and includes an indicator indicating that the geographical position of the target node and the radius is requested. The requesting service message is merged in a first header of a requesting datagram which is sent to the target node. A reply datagram is received from the target node and a reply position message component is extracted from the received reply datagram. A reply position message component is extracted from a second header of the received reply datagram. The first geographical position of the target node and the radius from the extracted reply position message component is determined. A response to the received request is provided based on the determined radius and the determined geographical position.

摘要： Provided are apparatuses and methods for transmitting and receiving quick access services. For example, a mobile terminal may receive a data stream containing a quick access service of a particular type. The quick access service may have a fixed Packet Identification (PID) and/or fixed IP address. The fixed PID and/or fixed IP addressed may be associated with a quick access service based on the particular type of the quick access service. In another example, a mobile terminal and a user interface on a mobile terminal may provide a menu for selection of an access mode for accessing the quick access service. Also, a quick access service may be selected based on the type of the quick access service.

摘要： Provided are apparatuses and methods for transmitting and receiving a service discovery section (SDS) associated with a service. In one example, the SDS corresponds to a channel identifier and contains mapping information. The mapping information may map the channel identifier to a packet identifier for the service. In addition, the mapping information may contain mapping information for IP addresses corresponding to the channel identifier, information identifying the network for transmission, a cell in which data is transmitted or priority information for the data.
