Abstract: This disclosure relates to broadcast information block assistance for a wireless device. The wireless device may obtain a first plurality of broadcast information blocks from a first base station. The wireless device may receive a second plurality of broadcast information blocks associated with the first base station from a source other than the first base station. The wireless device may determine if the second plurality of broadcast information blocks match the first plurality of broadcast information blocks based on version information specified in the first plurality of broadcast information blocks. When the broadcast information blocks match, the wireless device may use the first and second pluralities of broadcast information blocks to perform communication with the first base station without obtaining the second plurality of information blocks from the first base station.

Abstract: The disclosed embodiments provide a system that processes incoming network packets to an electronic device. The system includes an analysis apparatus that maintains a list of accepted incoming packet attributes for the electronic device based on outgoing packets from the electronic device. The system also includes a filtering apparatus that compares a first set of header information for an incoming packet to the list. If the first set of header information is not included in the list, the filtering apparatus discards the incoming packet. If the first set of header information is included in the list, the filtering apparatus enables subsequent processing of the incoming packet on the electronic device by, for example, providing the incoming packet to a transport-layer mechanism on the electronic device for subsequent processing of the incoming packet by the transport-layer mechanism.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a postponement of a data service request are described. A UE may detect a data service request failure during cell reselection and postpone a resend of the data service request based on a status of the cell reselection. The status may be an indication that the UE is attempting to camp on a cell or that the UE is monitoring one or more metrics associated with cell reselection. To postpone the data service request, the UE may postpone the data service request for a specified period of time or until the cell reselection is complete. The status may be monitored on a first layer of a protocol stack and the data service request may generated by a second layer of the protocol stack. The postponement may be for a fixed or variable time period.

Abstract translation: 描述用于执行数据服务请求延迟的用户设备（UE）设备的设备，系统和方法。 UE可以在小区重选期间检测数据服务请求失败，并且基于小区重新选择的状态推迟数据业务请求的重发。 该状态可以表示UE尝试驻留在小区上，或者UE正在监视与小区重选相关联的一个或多个度量。 为了推迟数据服务请求，UE可以延迟数据服务请求一段指定的时间，或者直到小区重选完成。 可以在协议栈的第一层上监视状态，并且数据服务请求可以由协议栈的第二层生成。 推迟可能是固定的或可变的时间段。

Abstract: Methods and apparatus for dynamic search management in a multi-mode device. In one embodiment, a mobile device performs network search and acquisition by dynamically changing search delays and/or search frequencies. In one implementation, the mobile device adjusts the amount of time allocated for each network search based on e.g., previous network connection history (e.g., previously connected to a home network, previously connected to a roaming network), device conditions, user preferences, geographical information, etc. By focusing search effort on cellular technologies which have a high likelihood of success, the mobile device can greatly improve search time and reduce unnecessary power consumption.

Abstract: The disclosed embodiments provide a system that processes incoming network packets to an electronic device. The system includes an analysis apparatus that maintains a list of accepted incoming packet attributes for the electronic device based on outgoing packets from the electronic device. The system also includes a management apparatus that uses the list to classify an incoming packet to the electronic device as a solicited incoming packet or an unsolicited incoming packet. If the incoming packet is classified as the solicited incoming packet, the management apparatus enables subsequent processing of the incoming packet on the electronic device. If the incoming packet is classified as the unsolicited incoming packet, the management apparatus adjusts a triggering of radio dormancy in the electronic device based on the incoming packet.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract translation: 与包括基站（BS）的网络的连接可以由用户设备（UE）经由无线连接建立，用于使用在连续的不连续接收（C-DRX）模式中的半永久调度（SPS）进行通信。 可以相对于SPS激活命令和SPS间隔UL（对于上行链路）来调整SPS发送周期。 然后可以根据所确定的SPS发送周期在C-DRX持续时间周期期间发送数据。 在一些实施例中，调整SPS发送周期，使得在接收到SPS激活命令之后的第一C-DRX持续时间周期之后，SPS数据传输在每个随后的C-DRX持续时间段期间发生特定数量的子帧 比在第一个C-DRX持续时间段。 一旦UE设备在持续时间期间唤醒，可以在每个随后的C-DRX持续时间段中的SPS数据传输发生。

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a radio access technology (RAT) upgrade. A UE may initiate a background scan to upgrade RAT while camped on a first system in response to an occurrence of a first condition. The first system may include a first PLMN that operates according a first RAT. The UE may determine a second system operates according to a second RAT that provides upgraded service as compared to the first RAT. The second system may be included in one or more systems found during the background scan. The UE may attempt to register on the second system based on the second PLMN operating according to the second RAT. The first and second PLMNs may each have an associated operator preference and the first PLMN may be preferred over the second PLMN.

Abstract: Adjusting search and measurement periodicity based on device motion. A wireless device may camp on a serving cell. Signal strength, signal quality, and signal to noise ratio of the serving cell may be measured. If each is above a respective threshold, and if the wireless device is stationary, the periodicities at which searches and neighbor cell measurements are performed may be adjusted (e.g., increased) from baseline periodicities.
