US Patent 10205505 Communications methods and apparatus

Methods and apparatus for supporting efficient communications of time varying data are described. A wireless device monitors to detect receipt of a first identifier, e.g., an LTED OTACode, via a first network interface, said first identifier corresponding to first information that is available via the first network, said first information indicating a source of first time varying data and a description of the first time varying data. The wireless device monitors to detect receipt of a second identifier, e.g., a hash value, via a second network interface, e.g., a WIFI, interface. The wireless device determines if the first identifier was received on the first interface and if a second identifier, corresponding to the first identifier, was received on the second interface. The wireless device makes a decision whether or not to retransmit the second identifier. The wireless device retrieves, uses and/or supplies the first time varying data to other devices.
