    Abstract: Methods and user equipment devices (UEs) are disclosed for performing keep alive interval fallback. During an active connection with a remote network, a UE may operate in a steady state configuration wherein keep alive message are periodically sent to the remote network. The UE may determine that a keep alive message has failed to receive an acknowledgement (ACK) response. Based on the determination that the keep alive message has failed, the UE may trigger keep alive interval fallback, wherein the UE sends keep alive messages at a shorter duration for a predetermined period of time.

    Abstract: Some embodiments relate to a device that transmits/receives encrypted communications with another device. A first device, such as a smart phone or smart watch, may generate a message associated with a certain data class, which may determine the security procedure used in the communication of the message. The first device may establish an encryption session for the purpose of communicating the message to a second device. Prior to sending the message, the first device may wait until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the data class of the message. Similarly, after receiving the message, the second device may not be able to decrypt the message until encryption credentials are accessible according to certain conditions, which may be determined at least in part by the message data class.
