1. A method comprising:
- a mobile terminal receiving a delivery time of a digitally broadcast signaling table;
said mobile terminal determining that an update of the digitally broadcast signaling table is required for the mobile terminal; and
in response to the determining that the update is required for the mobile terminal, thenpowering down a receiver of the mobile terminal;
powering up the receiver at a time proximate to the delivery time; and
receiving the updated digitally broadcast signaling table.

Abstract
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.

13. A method comprising:
-
determining a transmission time when an updated version of a signaling table will be transmitted; forwarding a notification of the transmission time for digital broadcast transmission, said notification including relevance information identifying a type of broadcast service standard for which changes in the updated version of the signaling table are relevant, wherein the type of broadcast service standard is digital video broadcasting for handhelds (DVB-H); and forwarding the signaling table for digital broadcast transmission at a time proximate to the transmission time. - View Dependent Claims (14, 15, 16)

17. A device comprising:
-
a processor; a receiver configured to receive a digital broadband broadcast signal; and a memory storing machine-executable instructions that, when executed, cause the device to perform the following; receiving a delivery time for a digitally broadcast signaling table; storing the delivery time in the memory; determining that an update of the digitally broadcast signaling table is required for the device; and in response to the determining; powering down the receiver; subsequently powering up the receiver at a time proximate to the delivery time; and receiving the digitally broadcast signaling table. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A method comprising:
-
receiving a first signaling table via a DVB-H signal, the first signaling table comprising notification of a time offset and a version of a second signaling table; determining that an update of the second signaling table is required based at least in part on a DVB-H update flag included with the first signaling table; powering down a receiver; powering up the receiver at a time proximate to the time offset; and receiving the second signaling table via the DVB-H signal. - View Dependent Claims (26)

27. A computer-readable medium, storing instructions to cause a processor to perform the following:
-
receive a broadcast signaling table at a mobile device; receive an indication that a new version of the signaling table will be available, the indication including a service type identifier identifying a type of broadcast service standard whose information is changed in the new version; determine that changes in the new version do not include changes to a type of broadcast service standard received by the mobile device; and in response to the determining, retain an outdated version of the signaling table in the mobile device. - View Dependent Claims (28, 29)

30. A computer-readable medium, storing instructions to cause a processor to perform the following:
-
determine a transmission time when an updated version of a signaling table will be transmitted; forward a notification of the transmission time for digital broadcast transmission, said notification including relevance information identifying a type of broadcast service standard for which changes in the updated version of the signaling table are relevant, wherein the type of broadcast service standard is digital video broadcasting for handhelds (DVB-H); and forward the signaling table for digital broadcast transmission at a time proximate to the transmission time. - View Dependent Claims (31, 32, 33)
