  • Patent number: 9949296
    Abstract: Aspects of resolving conflicting configuration parameters during wireless communication include triggering reselection to a new cell from a current cell and determining that a user equipment (UE) is configured in a forward access channel (FACH) state and is waiting for a Layer 2 Acknowledgement (L2 ACK) message from a network entity when reselection to the new cell is triggered. Further, the aspects include performing a collision resolution procedure in response to the determination that the UE is configured in the FACH state and is waiting for the L2 ACK message. In some aspects, the collision resolution procedure establishes which one of a plurality of information elements (IEs) to choose for a reconfiguration procedure.

  • Patent number: 9949121
    Abstract: A method for authenticating a circuit switched (CS) call on a virtual subscriber identity module (VSIM) includes: authenticating the VSIM for a packet switched (PS) call connection using authentication information obtained from a remote server through a software subscriber identity module (soft-SIM) connection to the remote server; initiating a call connection on a CS radio access technology (RAT) between the VSIM and a first communication network; and authenticating the VSIM CS call connection to the first communication network through the VSIM PS connection in response to an authentication request for the call connection on the CS RAT.

  • Patent number: 9942805
    Abstract: The disclosure provides for a UE handling messages in wireless communication. The disclosure provides for a UE partially exchanging a first signaling-related message associated with a first UE configuration with a network entity and triggering a state transition message that initiates a change to a second UE configuration different from the first UE configuration. In an aspect, the UE determines that the first message has not been successfully received or successfully transmitted. In an aspect, the UE sends an indication message to coordinate discarding of the first message with the network entity and receives, after sending the indication message, a second signaling-related message associated with the second UE configuration. In another aspect, the UE, after partially sending a signaling-related message, receives a reconfiguration request associated with a second UE configuration. In an aspect, the UE determines that the message has not been successfully transmitted and causes a reconfiguration failure.

  • Publication number: 20170303181
    Abstract: Wireless communication at a user equipment (UE) is described. In some cases, a UE may determine that a voice call is about to be setup or in the process of being setup with a cell that supports voice calls. While the voice call is pending, the UE may be motivated to connect to a cell that does not support voice calls. The UE may recognize that the cell does not support voice calls and refrain from connecting to the cell until after the voice call setup, and/or the voice call itself, has completed.

  • Publication number: 20160316373
    Abstract: The present disclosure describes a method and an apparatus for managing security mode command (SMC) integrity failures at a user equipment (UE). For example, a method is provided for managing SMC integrity failures which receives a SMC message at the UE from a network entity. A message authentication code for data integrity (MAC-I) failure based at least on a mismatch of a security parameter at the UE may be detected at the UE. Moreover, a corrective action may be performed at the UE in response to the detection of the MAC-I failure at the UE.

  • Publication number: 20160212622
    Abstract: Aspects of the disclosure provide for a method of efficiently implementing security configurations for multiple domains between a network entity and a UE in a wireless system. For instance, this disclosure provides for a network entity sending to a UE a first security mode command for a first domain, receiving a first security mode complete message in response to the first security mode command, and sending a second security mode command for a second domain. In an aspect, the second security mode command is sent in response to receiving the first security mode complete message. In an aspect, the UE does not receive a RLC acknowledgement. In another aspect, the UE saves the second security mode command until it receives the RLC acknowledgement. In an aspect, the network entity sends the second security mode command in response to receiving a message protected with first security procedure parameters.

  • Publication number: 20160135114
    Abstract: Aspects described herein relate to throttling packet-switched (PS) call establishment in wireless communications. A circuit-switched (CS) call can be conducted by using a first radio access technology (RAT). A cell update (CU) procedure for a PS call using a second RAT can be detected as due to one or more conditions. A cause for the one or more conditions can be determined based on one or more parameters related to a transmitter or receiver.

  • Publication number: 20150365856
    Abstract: The present disclosure presents a method and an apparatus for managing radio resource control (RRC) state transitions at a user equipment (UE). For example, the method may include transmitting a reconfiguration complete message to a network entity, starting a reselection delay timer simultaneously with the transmitting of the reconfiguration complete message, identifying initiation of a cell reselection procedure at the UE, delaying the cell reselection procedure at the UE until the UE receives a layer 2 acknowledgement (L2 ACK) message from the network entity, stopping the reselection delay timer in response to receiving the L2 ACK message, and transitioning the UE to a cell_paging channel (cell_PCH) state from a cell_forward access channel (cell_FACH) state after the stopping of the reselection delay timer. As such, managing RRC state transitions at a UE may be achieved.

  • Publication number: 20150304061
    Abstract: Aspects are described for synchronizing a user equipment (UE) and at least one network entity at, for example, a Radio Link Control (RLC) layer entity. The aspects may include receiving a first status packet data unit (PDU). In some aspects, the first status PDU may be a most recent non-erroneous status PDU. Further, the aspects may include receiving a second status PDU. In some aspects, the second status PDU may be received subsequent to receiving the first status PDU. Moreover, the aspects may include determining whether the first status PDU and the second status PDU are transmitted from a same network entity. Additionally, the aspects may include performing a RLC reset based at least in part on a determination being made that the first status PDU and the second status PDU are transmitted from the same network entity.

  • Publication number: 20150271083
    Abstract: Techniques for configuring a window size are described. A user equipment (UE) may identify a first window size for communications between the UE and a source network and determine that the first window size is invalid for a target configuration of communications between the UE and a target network. When the first window size is invalid for the target configuration, the UE may calculate a second window size for the target configuration of communications between the UE and the target network based on one or more parameters of the target configuration. The calculation of the second window size may be based on one or more parameters of the target configuration. Moreover, the one or more parameters may at least include a stored window size from a previous configuration of the communications between the UE and the source network.

  • Patent number: 8688166
    Abstract: A communication device establishes a connection in a congested wireless communications network environment by systematically reducing a probability of attempting to connect to a strongest, but overly-congested, cell. A transceiver of the communications device attempts at least one first Random Access Channel (RACH) procedure with a first cell that is currently designated as a serving cell. A RACH controller of the communications device detects a failure to successfully connect to the first cell via the at least one first RACH procedure, autonomously determines, based at least on a probability value, which is greater than 0% and less than 100%, whether to de-prioritize the first cell for a period of time, and, in response to determining to de-prioritize the first cell, reduces a priority value assigned at the UE to the first cell for cell selection/reselection, and assigns a selected time period during which the priority value remains reduced.
