A method and related apparatus for performing wireless data offload in a public transportation vehicle comprising at least one access point and at least one data storage comprising a plurality of pieces of data, the method comprising: searching for available offload nodes in the vehicle; sending a request for wireless offload of the data at least to a first offload node, the request including one or more offload parameters; offloading, upon an acknowledgement from the first offload node, a first piece of data to the first offload node; and registering the first piece of data as offloaded to the first offload node.

Method for wireless data offload

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.

Method and system to signal network information in TPS bits

The present invention provides methods and apparatus for supporting geographical-based services in a communications system. In an embodiment of the invention, a terminal node (e.g., a wireless terminal) inserts geographical information into a header portion of an IPv6 datagram. The serving network utilizes the geographical information to support a geographical-based service. In another embodiment, a terminal node, which is located in a geographical area, receives service configuration information regarding service regions from a serving network and determines what services are supported in the geographical area. In an embodiment, header formats for the inserted geographical information in a propagated signal between a terminal node and a serving network are provided.

Geographical position extension in messaging for a terminal node

Systems and methods are provided for receivers of digital broadband broadcast signals to determine a time of delivery and a version of a particular signaling table. The receiver is able to determine whether an update of the signaling table is needed based on factors such as whether the update applies (e.g., a DVB-H specific change for a mobile terminal in a DVB-H network). The receiver may power down while awaiting delivery of the signaling table (or utilize the radio for other purposes), powering back up in time to receive the signaling table.

Methods and apparatus for signaling offsets and changes in digital broadcast networks

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.

Determining geographical position in IPV6 networks

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.

Method and system for providing quick service access

A method and apparatus are disclosed whereby a time-slicing approach to the delivery of packet data is enabled. The approach is particularly suited to enabling power management by mobile terminals where receiver demands otherwise place strenuous requirements on an internal power source such as a battery.

Content delivery

A method of limiting the quality of service of data transmission in a wireless telecommunications system, in which the quality of service of data transmission is defined by means of quality of service parameters. Subscriber-specific maximum values are defined for the quality of service parameters and stored in a database comprising subscriber data. When the terminal requests connection establishment defined with quality of service parameters, the subscriber-specific maximum values are checked in the database and they are compared with the quality of service parameters requested by the terminal. Depending on whether the quality of service parameters requested by the terminal are within the limits defined by the maximum values of the parameters or whether at least one quality of service parameter requested by the terminal exceeds the maximum value defined for said parameter, either a connection is established or connection establishment is rejected.
