  • Patent number: 9198008
    Abstract: A method of operating a cellular telephone comprises presenting a user with an option of a first rule or a second rule, and accepting a selection of the first rule or the second rule. The first rule relates to a voice message, and the second rule relates to a text message. The method determines that reception is not sufficient to establish communication, and stores an address of an intended recipient. The method also stores the voice message if the first rule was selected or the text message if the second rule was selected. When reception is sufficient to establish communication, the stored message is sent to the address.

  • Patent number: 9161082
    Abstract: A method includes determining a data capacity of a first network device of a plurality of network devices that provide content to a set-top box device. In response to the data capacity satisfying a first threshold and a second threshold, sending a first command to the first network device. The first command instructs the first network device to store media content associated with a particular channel corresponding to a predicted channel change request at the first network device. In response to the data capacity satisfying the first threshold and failing to satisfy the second threshold, sending a second command to the first network device and sending a third command to a second network device. The third command instructs the second network device to store the media content associated with the particular channel.
