  • Publication number: 20190141524
    Abstract: A system for transmission data protection includes user equipment (UE) and an access point. The access point sends a broadcast message that carries a public key for encryption. The UE receives and stores the public key for encryption. The UE obtains a global public key or a private key corresponding to the UE, and protects transmission data using the public key for encryption and the global public key or the private key corresponding to the UE.

  • Publication number: 20190041941
    Abstract: Micro-idle power in a subsystem of a portable computing device may be actively managed based on client voting. Each client vote may include a client activity status indication and a client latency tolerance indication. Votes are aggregated to provide an aggregate client latency tolerance, which may be used to obtain a set of micro-idle time values. Micro-idle timers in the subsystem may be set to associated micro-idle time values. The micro-idle timers determine whether one or more of the micro-idle time values have elapsed. A power management policy associated with each micro-idle time value determined to have elapsed may be applied to a portion of the subsystem.

  • Publication number: 20190021054
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be enabled for voice over long term evolution (VoLTE). The UE may include an audio layer to encode and decode voice information and a packet layer to transmit voice packets. The packet layer may store parameters related to a discontinuous reception (DRX) in a shared memory. The audio layer may obtain the DRX parameters and encode voice information based on the parameters. For example, the audio layer coding may be synchronized with the wake period of the DRX cycle. The audio layer may encode voice information during a wake up period of the packet layer DRX cycle, and the packet layer may transmit the voice packets while awake. The audio layer may perform back to back encodings at the beginning of the DRX cycle. The packet layer may extend the wake period to transmit the voice packets.

  • Publication number: 20190021002
    Abstract: A method for devices without SIM card (SD) to communicate directly with a core network. The method may be performed in the following matter. The SD registers with the core network through a cellular device (MD) in order to obtain a credential for the SD. The credential comprises Access ID, key, and control parameters. The SD then performs a mutual authentication directly with the core network using the credential. If the SD authenticates successfully with the core network, the SD is granted access to the servers via the core network.
