    Abstract: Systems, methods, and apparatuses for reducing delays associated with an attachment procedure are disclosed. In accordance with the present disclosure, a user equipment (UE) may initiate an attachment procedure with a network over a non-access stratum (NAS) layer and detect a condition that may delay completion of the attachment. Based on the detection, the UE may determine whether the condition may be resolved before failure in the attachment procedure. If the UE determines that the condition can be resolved before attachment failure, the UE may suspend a timer associated with the attachment procedure at the NAS layer to allow more time for the UE to complete an authentication associated with the attachment. Conversely, if the UE determines that the condition cannot be resolved before attachment failure, the UE may abort the attachment procedure with the network and initiate a fallback attachment procedure with the network via a different base station.

    Abstract translation: 公开了用于减少与附接过程相关联的延迟的系统，方法和装置。 根据本公开，用户设备（UE）可以通过非接入层（NAS）层发起与网络的附接过程，并检测可能延迟附件完成的状况。 基于检测，UE可以在附件过程中的故障之前确定该条件是否可以被解决。 如果UE在安装失败之前确定可以解决该情况，则UE可以在NAS层挂起与该附件过程相关联的定时器，以允许更多的时间来完成与附件相关联的认证。 相反，如果UE在安装失败之前确定该条件无法解决，则UE可以中止与网络的连接过程，并且经由不同的基站发起与网络的后退连接过程。

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a cellular modem may transmit, to an applications processor, an indication to use a non-Third Generation Partnership Project (non-3GPP) interworking function (N3IWF) for non-access stratum (NAS) signaling. Accordingly, the cellular modem may establish a first virtual interface with the applications processor. The cellular modem may further perform an Internet Key Exchange (IKE) procedure with a core network using the first virtual interface and the N3IWF and transmit a key generated during the IKE procedure to the applications processor. Numerous other aspects are described.

    IPC: H04W36/00

    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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. Further, the apparatus may be configured to determine that content is available for reception based on broadcast context information. In an aspect, the apparatus may be in an idle or inactive mode and may be associated with a first base station that is associated with a first radio access technology (RAT) that does not support broadcasting of the content. The apparatus may be further configured to receive a release message from the first base station, the release message including redirection information indicating a second base station associated with a second RAT that supports broadcasting of the content, establish a connection with the second base station based on the redirection information, and receive the content from the second base station using the second RAT.

    Abstract: A new radio (NR) user equipment (UE) registration procedure that may be executed by a UE and a network is disclosed, resulting in a UE registration that may be more efficient than existing UE registration procedures. For example, the UE registration procedure may utilize messaging between an extensible authentication protocol (EAP) component and a non-access stratum (NAS) component to abort the registration procedure when a non-recoverable EAP failure occurs, or suspend or re-start a NAS registration timer when a recoverable EAP failure occurs.
