Abstract: A mobile device collects received information and processes it. In some instances, the mobile device detects, based on the collected information, that a base station is likely not legitimate, i.e., it is likely a fake base station, and the mobile device bars communication with the base station for a time. In some embodiments, the mobile device determines, based on the received information, that the base station is a genuine base station. When the mobile device determines that the base station is a genuine base station or the mobile device does not determine that it is likely the base station is a fake base station, the mobile device allows or continues communication with the base station.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively enhance the quality of service (QoS) configuration of a bearer of communications conducted over a cellular network between a UE application and a server. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or whether the UE is permitted to request or access enhanced QoS functionality. The UE may then send a request to the cellular network indicating the requested QoS parameters, and the network may adjust the QoS configuration of the bearer in response. The UE and the network may perform routine QoS measurements and exchange information in order to adaptively maintain and optimize the QoS configuration. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.

Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

Abstract: This disclosure relates to techniques for a wireless device to detect and operate in an elevator or elevator-like conditions. The wireless device may establish a cellular link with a cellular base station. One or more conditions associated with being in an elevator may be detected. The wireless device may determine to operate in an elevator mode based at least in part on detecting the one or more conditions associated with being in an elevator. The wireless device may operate in the elevator mode. One or more conditions associated with exiting an elevator may be detected. The wireless device may determine to operate in a normal mode based at least in part on detecting the one or more conditions associated with exiting an elevator. The wireless device may operate in the normal mode.

Abstract: This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.

Abstract: A method, system, and apparatus are described for managing a device in a mixed wireless communication system. A device may decide to scan or not scan for a cell based on (or at least on) updating information. The updating information may be used together or individually. The updating information may be maintaining a time window in conjunction with a device's motion status, maintaining a list that tracks cell identity in areas of non-service, or utilizing network deployment information.

Abstract: Transitioning a UE from a first RAT to a third RAT in an area having a first RAT, a second RAT, and a third RAT. The first RAT may be a second generation RAT, the second RAT may be a third generation RAT, and the third RAT may be a fourth generation RAT. The network of the first RAT may not provide information (e.g., a neighbor list) for the third RAT. The UE may use information to perform measurement of one or more base stations of the third RAT without attaching to the second RAT. For example, the UE may use pre-stored information to perform measurement of the third RAT. Alternatively, or additionally, the UE may receive the information (e.g., from a system information block) from the second RAT without attaching to the second RAT.

Abstract translation: 在具有第一RAT，第二RAT和第三RAT的区域中将UE从第一RAT切换到第三RAT。 第一RAT可以是第二代RAT，第二RAT可以是第三代RAT，并且第三RAT可以是第四代RAT。 第一RAT的网络可能不提供第三RAT的信息（例如，邻居列表）。 UE可以使用信息来执行第三RAT的一个或多个基站的测量，而不附加到第二RAT。 例如，UE可以使用预先存储的信息来执行第三RAT的测量。 或者或另外，UE可以从第二RAT接收信息（例如，来自系统信息块），而不附加到第二RAT。
