Smart signboard-based notification system
First Claim
1. A method of notifying a user of a wireless mobile device of contents of a signboard, comprising:
- downloading, by the wireless mobile device, a lookup table of signboard warning messages;
receiving, at the wireless mobile device, a notification in a vendor-specific information element of a broadcast message transmitted on a broadcast channel of a short-range wireless network, wherein the vendor-specific information element is reserved for conveying information other than information defined by a short-range wireless network standard, wherein the vendor-specific information element includes a primary bitmask indicating that the notification is included in the broadcast message and a secondary bitmask representing an index to the lookup table of signboard warning messages, and wherein an entry in the lookup table corresponding to the index represents the contents of the signboard;
decoding, by the wireless mobile device, the notification in the broadcast message transmitted on the broadcast channel of the short-range wireless network without connecting to the short-range wireless network; and
providing, by the wireless mobile device, data representing the notification to the user of the wireless mobile device based on the entry in the lookup table corresponding to the index.

Abstract
Disclosed are techniques for notifying a user of a wireless mobile device of the contents of a signboard. In an aspect, the wireless mobile device receives a notification in a broadcast message transmitted on a broadcast channel of a short-range wireless network, the notification representing the contents of the signboard, decodes the notification without connecting to the short-range wireless network, and provides data representing the notification to the user of the wireless mobile device. In an aspect, a wireless access point coupled to the signboard encodes the notification in the broadcast message transmitted on the broadcast channel of the short-range wireless network supported by the wireless access point and broadcasts the notification in the broadcast message transmitted on the broadcast channel of the short-range wireless network.

1. A method of notifying a user of a wireless mobile device of contents of a signboard, comprising:
-
downloading, by the wireless mobile device, a lookup table of signboard warning messages; receiving, at the wireless mobile device, a notification in a vendor-specific information element of a broadcast message transmitted on a broadcast channel of a short-range wireless network, wherein the vendor-specific information element is reserved for conveying information other than information defined by a short-range wireless network standard, wherein the vendor-specific information element includes a primary bitmask indicating that the notification is included in the broadcast message and a secondary bitmask representing an index to the lookup table of signboard warning messages, and wherein an entry in the lookup table corresponding to the index represents the contents of the signboard; decoding, by the wireless mobile device, the notification in the broadcast message transmitted on the broadcast channel of the short-range wireless network without connecting to the short-range wireless network; and providing, by the wireless mobile device, data representing the notification to the user of the wireless mobile device based on the entry in the lookup table corresponding to the index. - View Dependent Claims (2, 3, 4, 5, 6)

7. A method of notifying a wireless mobile device of contents of a signboard, comprising:
-
encoding, by a wireless access point coupled to the signboard, a notification in a vendor-specific information element of a broadcast message to be transmitted on a broadcast channel of a short-range wireless network supported by the wireless access point, wherein the vendor-specific information element is reserved for conveying information other than information defined by a short-range wireless network standard, wherein the vendor-specific information element includes a primary bitmask indicating that the notification is included in the broadcast message and a secondary bitmask representing an index to a lookup table of signboard warning messages on the wireless mobile device, and wherein an entry in the lookup table corresponding to the index represents the contents of the signboard; and broadcasting, by the wireless access point, the notification in the broadcast message on the broadcast channel of the short-range wireless network, wherein the notification being broadcast in the broadcast message transmitted on the broadcast channel of the short-range wireless network enables the wireless mobile device to decode the notification without connecting to the short-range wireless network. - View Dependent Claims (8, 9, 10)

11. An apparatus for notifying a user of a wireless mobile device of contents of a signboard, comprising:
-
a transceiver of the wireless mobile device configured to download a lookup table of signboard warning messages and receive a notification in a vendor-specific information element of a broadcast message transmitted on a broadcast channel of a short-range wireless network, wherein the vendor-specific information element is reserved for conveying information other than information defined by a short-range wireless network standard, wherein the vendor-specific information element includes a primary bitmask indicating that the notification is included in the broadcast message and a secondary bitmask representing an index to the lookup table of signboard warning messages, and wherein an entry in the lookup table corresponding to the index represents the contents of the signboard; at least one processor of the wireless mobile device configured to decode the notification in the broadcast message transmitted on the broadcast channel of the short-range wireless network without connecting to the short-range wireless network; and a user interface of the wireless mobile device configured to provide data representing the notification to the user of the wireless mobile device based on the entry in the lookup table corresponding to the index. - View Dependent Claims (12, 13)

14. An apparatus for notifying a wireless mobile device of contents of a signboard, comprising:
-
at least one processor of a wireless access point coupled to the signboard configured to encode a notification in a vendor-specific information element of a broadcast message to be transmitted on a broadcast channel of a short-range wireless network supported by the wireless access point, wherein the vendor-specific information element is reserved for conveying information other than information defined by a short-range wireless network standard, wherein the vendor-specific information element includes a primary bitmask indicating that the notification is included in the broadcast message and a secondary bitmask representing an index to a lookup table of signboard warning messages on the wireless mobile device, and wherein an entry in the lookup table corresponding to the index represents the contents of the signboard; and a transceiver of the wireless access point configured to broadcast the notification in the broadcast message on the broadcast channel of the short-range wireless network, wherein the notification being broadcast in the broadcast message transmitted on the broadcast channel of the short-range wireless network enables the wireless mobile device to decode the notification without connecting to the short-range wireless network. - View Dependent Claims (15, 16)
