摘要： A method and apparatus for a first node to establish a wireless connection with a second node includes determining a reception time period of the second node during which a radio of the second node is turned on to receive signals, and an interval time period between commencement of reception periods of the second node, determining an event, in response to determining the event, transmitting a message to the second node a predetermined number of times, wherein a first time between transmission of the message is substantially equal to the reception time period, and the predetermined number of times that the message is transmitted is a positive integer that is equal to a quotient of the interval time period divided by the first time, rounded up to the next larger positive integer if the quotient includes a remainder.

摘要： A system and method for implementing fallback on a wireless device for circuit switched fallback from a first network that does not provide a circuit switched domain service is presented. A paging message is received from the first network. The paging message instructs the wireless device to implement circuit switched fallback to a circuit switched network. The paging message is inspected for information indicative of a service associated with the paging message, and a channel type suitable for the service is determined from the information indicative of the service. A request message for initiating the establishment of a radio connection is transmitted. The request message identifies the suitable channel type, and the service is used on the circuit switched network.

摘要： A method for improving reliability of Voice over LTE (VoLTE)/Video over LTE (ViLTE) calls includes detecting, by a User Equipment (UE) camped on a first Radio Access Technology (RAT), a problem with a radio connection on the first RAT at a first time. After detecting the problem with the radio connection, the UE blocks Non-Access Stratum (NAS) registration on a second RAT in a time period between the first time and a second time later than the first time. The second RAT is different than the first RAT.

摘要： A method and network element for sending a transition indication to transition a user equipment to a different state or mode, the method receiving a configuration message from a network; and transmitting a transition indication from the user equipment, the transition indication only includes a cause if the configuration message contains an inhibit transition indication. Also, a method and user equipment for processing a transitioning indication from a user equipment indicating the user equipment desires a transition to a different state or mode, the method comprising: receiving the transition indication from the user equipment; if the transition indication contains a cause: releasing a signaling connection of the user equipment or transitioning the user equipment to a different state or mode; and if the transition indication does not contain the cause: releasing the signaling connection.

摘要： In some examples, a controller receives information of a route of a vehicle, and selects a first parameter set from among a plurality of parameter sets based on the route of the vehicle, the plurality of parameter sets corresponding to different conditions of usage of the vehicle, where each parameter set of the plurality of parameter sets includes one or more parameters that control adjustment of one or more respective adjustable elements of the vehicle. The controller causes application of the first parameter set to control a setting of the one or more adjustable elements of the vehicle.
