Abstract: This disclosure describes a communication system associated with a radio access technology (RAT). The communication system includes an Internet protocol (IP) multimedia subsystem (IMS) server, and one or more processors configured to perform operations. The operations include receiving, from a user equipment device (UE) camped on the RAT, a request for IMS Packet Data Unit (PDU) establishment or IMS session initiation protocol (SIP) registration; sending to the UE a rejection message associated with the SIP registration or the IMS PDU establishment; receiving, from the UE, an IMS failure message that comprises an IMS failure cause; determining, based on the IMS failure message, whether the IMS failure cause is temporary or permanent; and responsive to determining that the IMS failure is temporary, temporarily disabling the RAT for the UE.

Abstract: Methods and apparatus for accepting software updates without interruption of ongoing services. Various embodiments are adapted for maintaining service continuity in multi-mode devices such as cellular devices. In one exemplary implementation, unlike prior art solutions (which interrupt user identity module software to implement changes to the network access software), unnecessary updates can be postponed or otherwise scheduled so as to minimize or eliminate service or user experience impact.

Abstract translation: 用于接受软件更新而不中断正在进行的服务的方法和装置。 各种实施例适用于在诸如蜂窝设备的多模式设备中维持服务连续性。 在一个示例性实现中，与现有技术解决方案（其中断用户身份模块软件以实现对网络访问软件的改变）不同，可以推迟或以其他方式调度不必要的更新，以便最小化或消除服务或用户体验的影响。

Abstract: A wireless electronic device having first and second baseband processors is provided. In one suitable arrangement, radio-frequency power splitters and adjustable low noise amplifiers may be form in the receive paths. The use of power splitters allow signals associated with the first and second baseband processors to be received in parallel. In another suitable arrangement, radio-frequency switches are used in place of the power splitters. The states of the switches may be controlled using at least one of the first and second baseband processors. The use of switches instead of power splitters requires that wake periods associated with the first baseband processor and wake periods associated with the second baseband processor are non-overlapping. To ensure minimal wake period collision, a wake period associated with the second baseband processor may be positioned at a midpoint between two successive wake periods associated with the first baseband processor.

Abstract: Apparatuses, systems, and methods for SoR list management and PLMN selection based on an SoR list. A UE may receive an SoR container which may include a list of OPLMNs. The UE may store a prior list of OPLMNs stored on a USIM of the UE on a memory of the UE. The UE replace the prior list of OPLMNs stored on the USIM with the list of OPLMNs included in the SoR container. The UE may consider the prior list of OPLMNs as a lower priority list as compared to the list of OPLMNs stored on the USIM. Additionally, in response to determining to move from a current PLMN, the UE may scan for a new PLMN based on the list of OPLMNs stored on the USIM.

Abstract: A processor in a mobile wireless device provisions a user identity module (UIM) card in the mobile wireless device in response to a user command. The processor detects a user command to provision the UIM card and reads a provisioning status of the UIM card from a UIM card provisioning status file in the UIM card. When the provisioning status is “not provisioned”, the processor establishes a bearer independent protocol (BIP) data connection to a server in a wireless network and exchanges provisioning data between the server and the UIM card until the UIM card commands the processor to close the BIP data connection. In representative embodiments, the UIM card provisioning status file includes fields for a UIM card provisioning status, a UIM card software version and a UIM card provisioning date/time, and the processor updates the fields during provisioning.

Abstract: This disclosure describes a user equipment device (UE). The UE includes one or more antennas; one or more radios, where each of the radios is configured to perform cellular communication using a plurality of radio access technologies (RATs) that support voice over an Internet protocol (IP) multimedia subsystem (IMS); one or more processors coupled to the one or more radios, where the one or more processors are configured to cause the UE to perform operations including: sending, via a first RAT, a first request for IMS registration to an IMS server; receiving, from the IMS server, an IMS rejection message indicating failure of the IMS registration; determining, based on the IMS rejection message, that the IMS registration failure is temporary; responsively re-attempting IMS registration with the IMS server; and determining to camp on the first RAT in response to receiving an IMS acceptance message from the IMS server.

Abstract: User equipment devices (UEs) and methods are described for performing single network slice selection assistance information (S-NSSAI)-aware public land mobile network (PLMN) selection in a roaming scenario. A mapping list is received that includes a mapping of a plurality of public land mobile networks (PLMNs) to corresponding S-NSSAI values. The mapping list is received from a home PLMN (HPLMN) of the UE over non-3rd generation partnership (non-3GPP) access, from a server, or from a Universal Mobile Telecommunications Service (UMTS) subscriber identity module (USIM) of the UE. An available PLMN is determined that is mapped to a preferred S-NSSAI value of the UE based on the mapping list. A connection is established with the available PLMN.

Abstract: A user equipment (UE) is configured to prioritize a plurality of Public Land Mobile Networks (PLMNs) from an aggregate roaming priority public land mobile network (RPPLMN) list containing the plurality of PLMNs into a plurality of prioritized PLMNs and connect to a selected PLMN from the plurality of prioritized PLMNs based on a priority of the selected PLMN. The UE is further configured to determine if an application processor (AP) assisted location service is available, wherein the AP-assisted service is configured to identify a plurality of deployed PLMNs and a plurality of frequencies used by the plurality of deployed PLMNs at a current geographical location of the UE and when the AP) assisted location service is available, determining if a registered PLMN (RPLMN) is valid in a current mobile country code (MCC).
