Abstract: A method is provided. The method may be performed by a UE. The method includes attempting to attach to or to perform a tracking area update in an EPS network to obtain voice services for a number of times. The method includes starting a modified timer based on a failure to attach to or to perform the tracking area update in an EPS network for the number of times and based on a configuration parameter. The modified timer may be modified based on a default timer. The method includes keeping an S1 mode enabled when starting the modified timer. The method includes attempting to obtain the voice services based on one or more access technologies other than EPS. The method includes attaching to or performing a tracking area update in the EPS network to obtain voice services based on the modified timer.

Abstract: Methods and apparatus are provided for avoiding attempts by a UE to attach to a RAT network when that RAT network is unavailable. According to certain aspects, the UE may detect scenarios when the RAT network is unavailable and take preemptive action to prevent the UE from attempting to acquire service on that RAT. For example, the UE may effectively remove that RAT from a list of supported RATs by sending a UE capability message indicating that RAT is not supported, which may prevent network-initiated transitions of the UE to that RAT. The UE may also remove the unavailable RAT from an internal list of supported RATs, which may prevent UE-initiated transitions to that RAT.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving data service availability. Certain aspects provide methods and apparatus for wireless communications by a UE including determining, while the UE is in a coverage area of a first network, that a connection to a second network, comprising a packet data network (PDN), is disconnected locally, and taking at least one action to avoid a rejection of a request to connect to the second network.

Abstract: Methods, systems, and devices for wireless communication are described for inter-RAT mobility from a first radio access technology (RAT) to a second RAT, including cases in which different RATs correspond to different generations of networks. Approaches described herein include providing a preemptive indication of inter-RAT mobility for one or more geographic areas such to a user equipment (UE). The UE can thus use a mobility procedure to transition from the first RAT to the second RAT that is supported in the UE's location without first attempting an unsupported mobility procedure, reducing transition latency.

Abstract: Techniques are described for power conservation in emergency broadcast message reception in a wireless communications system. In accordance with a method for conserving power, one or more segments of an emergency broadcast message in an access stratum are received. The emergency broadcast message is identified as a duplicate emergency broadcast message based at least in part on one or more identifiers of the received one or more segments. The receipt of additional segments of the emergency broadcast message is terminated.

Abstract: Aspects of the disclosure are directed to congestion control in a user equipment in connected mode including upon receipt of a trigger, using a register to determine if a data packet transmission has been initiated by an application associated with the UE, wherein the UE is in a connected mode; retrieving an Application-specific Congestion control for Data Communication (ACDC) category mapped to the application associated with the UE, wherein a mapping between the ACDC category and the application is performed a priori to a transition to the connected mode; retrieving at least one access control parameter based on the ACDC category; and determining if the application is allowed to perform the data packet transmission based on the at least one access control parameter.
