  • Patent number: 9615217
    Abstract: Distributing messages received by a cellular device via cellular broadcast to additional electronic devices. The cellular device may receive a first message via a cellular broadcast technique. The cellular device may discover another electronic device. The cellular device may provide an indication of the first message to other electronic device. The indication of the first message may cause the other electronic device to provide a user alert at the other electronic device.

  • Patent number: 9584995
    Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform emergency calling. A UE may receive an indication to initiate an emergency call. The UE may select a cell on which to initiate the emergency call. If a serving cell of a first SIM of the UE is not available for the emergency call, the UE may utilize information from a second SIM of the UE as part of selecting the cell on which to initiate the emergency call. The information from the second SIM may include an indication of a serving cell of the second SIM. Alternatively or in addition, the information from the second SIM may include an indication of one or more neighboring cells of the second SIM. The emergency call may be initiated via the selected cell using the first SIM.

  • Publication number: 20160345245
    Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to search for service. A UE may determine that a first SIM of the UE is out-of-service. The UE may scan for service for the first SIM of the UE using a second SIM of the UE. An indication may be provided to the first SIM if service (or service information) is found for the first SIM. If the second SIM is also out-of-service, the UE may scan for service for the first SIM and the second SIM jointly.

  • Publication number: 20160345244
    Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform system selection. A UE may determine to perform system selection for a first SIM of the UE. Information, such as serving cell and/or neighboring cell information, may be obtained from a second SIM of the UE. System selection for the first SIM may be performed based at least in part on the information obtained from the second SIM.

  • Patent number: 9145036
    Abstract: The present disclosure provides a shock absorber apparatus that includes a bump stopper coupled to a piston rod of a shock absorber. A piston housing comes into contact with the bump stopper when the shock absorber is moved vertically. A support supports a spring surrounding the piston housing. An air cap extends from an upper end of the piston housing to the support so as to cover the piston housing and has an upper surface through which a piston rod passes, a side surface downwardly extending from an end of the upper surface, and an air channel through which compressed air of the bump stopper is guided and discharged to the support.

  • Patent number: 9148847
    Abstract: A method for implementing mobile device-initiated inter-radio access technology (I-RAT) handovers between networks includes a wireless device communicating with a first network using an internet protocol (IP) address that was received from the first network during an initial attachment procedure. The wireless device may initiate an I-RAT handover procedure to connect to a second wireless network using a configuration message that includes a handover attach type. Once the connection with the second network is established, the wireless device may receive the information from the second wireless network using the same IP address. The wireless device may force the wireless device into dormancy and prevent data transfer, and initiate another I-RAT handover procedure to upgrade and connect to the first network, by sending an attach request message that includes a handover attach type.

  • Publication number: 20130273908
    Abstract: A user equipment (UE) device may communicate according to at least two telecommunication standards. The UE may generate a second preferred roaming list based on a first preferred roaming list. The first preferred roaming list may indicate geographic locations which support a first telecommunication standard, of which some may also support a second telecommunication standard. The second preferred roaming list may indicate geographic locations which support only the first telecommunication standard and may also indicate geographic locations which support both the first telecommunication standard and the second telecommunication standard. The second preferred roaming list may be used to perform roaming, which may facilitate the UE avoiding searching for the second telecommunication standard in geographic locations which support only the first telecommunication standard.
