Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for sending a reduced size message. One of the methods includes receiving, by a wireless device, a request to send, over a wireless network, a message comprising one or more phrases; determining that a connection quality for the wireless network does not satisfy a connection quality threshold; generating, responsive to determining that the connection quality threshold is not satisfied, a reduced-size message based at least in part on the one or more phrases; and sending, by the wireless device and via the wireless network, the reduced-size message.
Core Innovation
The invention describes reducing the size of a wireless message when connection quality falls below a threshold, particularly for important or emergency messages. The described approaches include mapped phrase codes, natural language processing-based next-phrase prediction, human-readable summaries, and model-based bit-stream encoding. A receiving device uses a decompression engine and phrase-to-code mapping to reconstruct message content.
The disclosure addresses the need to transmit messages when connection quality is low and utilizes message-size reduction as the approach. The system transmits a fuller message when connectivity improves. The system receives a message with an element indicating whether phrases from an original message are omitted or included, decides whether to decompress the message, and performs actions based on that decision.
Claims Coverage
The claims identify two independent claims comprising two inventive features directed to a computer-implemented method and an apparatus.
Message-element-based decompression decision
Independent claim 1 covers receiving a wireless message whose element indicates that the first device has a decompression engine and that the message does not comprise one or more phrases from an original message. The device uses that determination to decide whether to decompress the message and performs one or more actions based on the decompression decision.
Apparatus-based message and address determination
Independent claim 11 covers an apparatus that receives a wireless message and evaluates an included element to determine whether the message represents phrases from an original message and is not a reduced-size message. The determination includes whether the first device has a predetermined address; the apparatus then decides whether to decompress the message and performs one or more actions based on that decision.
Together, the independent claims cover method and apparatus implementations that use information in a received wireless message to determine whether decompression is appropriate, followed by actions based on that determination.
Stated Advantages
Improves the probability and latency of message delivery.
Reduces bandwidth use, network congestion, retransmissions, and transmission power.
Documented Applications
Wireless messaging, particularly the transmission of important or emergency messages when connection quality is low.
An emergency services system is identified as a predetermined system relevant to the apparatus's decompression decision.
