摘要： This disclosure relates to out of service recovery techniques for an accessory device. According to some embodiments, the accessory device may receive cellular communication system selection information from a paired device. The accessory device may store the communication system selection information. At some point, it may be determined that the accessory device has lost cellular communication service. The accessory device may perform a cellular communication service scan utilizing the system selection information received from the paired device along with its own historical information and location based frequency lists.

摘要： 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.

摘要： Instead of barring an LTE network for the Long Bar Time duration (LBT) if the LTE cell doesn't support CSFB, a wireless communication device may perform a scan for LTE networks before expiration of the LBT if the UE has changed its location. When the UE is in LTE acquisition mode, or the necessary information about a CS network for CSFB is unavailable, the UE may maintain its state on both the LTE and CS network, and check CS paging messages to see if the UE can decode any status. Unlike for CSFB, checking for overhead messages may be performed over the LTE system, and the UE may wake up on CS pages to determine if a suitable network is available. By maintaining its state on both types of networks, the UE may use LTE for data services which would otherwise be provided by different systems for the CS networks when messages transmitted over LTE do not include CS registration information.
摘要翻译：如果LTE小区不支持CSFB，则不是将LTE网络限制在长时间段时间长度（LBT），如果UE改变了其位置，则无线通信设备可以在LBT到期之前对LTE网络执行扫描。当UE处于LTE获取模式时，或者关于CSFB的CS网络的必要信息不可用时，UE可以在LTE和CS网络上保持其状态，并检查CS寻呼消息以查看UE是否可以解码任何状态。与CSFB不同，可以通过LTE系统执行开销消息的检查，并且UE可以在CS页面上唤醒以确定合适的网络是否可用。通过在两种类型的网络上维持其状态，当LTE发送的消息不包括CS注册信息时，UE可以使用LTE用于数据业务，否则这些数据业务将由CS网络的不同系统提供。
