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: Apparatus and methods to support parallel communication using multiple subscriber identities in a wireless communication device via multiple subscriber identity modules (SIMs) are disclosed. A representative method includes establishing a connection with a first wireless network via a first wireless cellular protocol software stack for a first subscriber identity associated with a first subscriber identity module; registering with a second wireless network via a second wireless cellular protocol software stack for a second subscriber identity associated with a second subscriber identity module; and receiving radio frequency signals from the second wireless network via the second wireless cellular protocol software stack in parallel with communicating with the first wireless network via the first wireless cellular protocol software stack.

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: Apparatus and methods to manage data connections to multiple wireless networks in a wireless communication device supporting multiple subscriber identities via multiple subscriber identity modules (SIMs) are disclosed. A representative method includes detecting an application request to establish a data connection; obtaining a preference for prioritization of data connections for the multiple SIMs; and based on the preference, establishing the data connection with a wireless network associated with one of the multiple SIMs. In representative embodiments, the preference is based on a user specified or default prioritization of the multiple SIMs, an order of radio access technologies (RATs), one or more quality metrics, data rates supported, and/or availability of wireless local area networks for the data connections.

Abstract: Apparatus and methods to reuse wireless circuitry to communicate with multiple wireless networks to support multiple subscriber identities in a wireless communication device are disclosed. A representative method includes receiving signaling messages for a second subscriber identity from a second wireless network while connected to a first wireless network for a first subscriber identity. A portion of radio frequency wireless circuitry is reconfigured to communicate with the second wireless network to establish a signaling channel and respond to signaling messages received from the second wireless network. The portion of radio frequency wireless circuitry is reconfigured between the first and second wireless networks to maintain a connection with the first wireless network while also receiving from the second wireless network limited information that can be provided to a user.

Abstract: Generating and using a device-type specific preferred public land mobile network (PLMN) list for roaming PLMN selection. Wireless devices sharing one or more common characteristics may be tasked with collecting roaming PLMN selection data. That data may be collected and used to generate a preferred PLMN list specific to wireless devices sharing those common characteristics. The preferred PLMN list may be distributed to wireless devices sharing those common characteristics, which may then use it in conjunction with roaming PLMN selection.

Abstract: A method to be performed by a wireless station having a wireless transceiver configured to establish a connection to a network, a processor and a non-transitory computer readable storage medium. The method includes receiving information during a first reception segment of a discontinuous reception cycle, wherein the discontinuous reception cycle includes the first reception segment and a first idle segment, performing a first measurement that begins during the first reception segment and performing a second measurement, wherein the second measurement begins prior to an end of the first measurement.

Abstract: In a wireless communication system, a user equipment device (UE) may undertake a circuit-switched fallback (CSFB) process by using or more secondary radio frequency (RF) receive chains to search for candidate circuit-switched (CS) cells, in parallel with using a primary RF receive chain to wait for an extended service request (ESR) response. The UE may send, using a first RF receive chain, an ESR message on a packet-switched (PS) network in response to receiving a CS voice call page on the PS network. The UE may also start an ESR timer upon sending the ESR message, and monitor, using the first RF receive chain, for receipt of an ESR response on the PS network. While monitoring for receipt of the ESR response, the UE may use a second RF receive chain to acquire an initial CS network, and detect whether the ESR timer expires before the ESR response is received.

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.
