摘要： Systems and methods for managing data transfers between a secure location and a less secure location. A data transfer checker operating on a mobile device determines whether an attempted data transfer between two locations is permitted. If it is not permitted, then the data transfer is prevented and the user may be notified of the data transfer prevention.

摘要： Systems and methods are disclosed for identifying at least one cause of noise in a vehicle audio system. The vehicle audio system may include a plurality of audio channels. Acoustic output may be generated and received through each of the audio channels. Acoustic input may be received from one or more of the audio channels and may be processed to generate processed acoustic input. The processed acoustic input may include a frequency response of the acoustic input. The processed acoustic input may be compared to corresponding channel target input and at least one deviation may be determined. A cause of the at least one deviation may then be determined based on a relationship between the at least one deviation and a set of resolved indications of cause, each of the set of resolved indications of cause corresponding to at least one of a set of recorded causes.

摘要： A user equipment implements a method of processing indication messages, such as SCRI (signalling connection release indication) messages. The user equipment (UE) maintains a count of how many indication messages with a cause set have been sent by the UE while in at least one radio resource control (RRC) state. Various conditions are provided for resetting the count. These include receiving packet switched (PS) data by the UE and transmitting packet switched (PS) data.

摘要： A method implemented by a network node is disclosed. The method includes: obtaining registration state information associated with a user equipment (UE) from a first core network node, the registration state information indicating at least one of fourth-generation (4G) UE single radio voice call continuity (SRVCC) capability or fifth-generation (5G) UE SRVCC capability for the UE, wherein the UE is registered with a first IMS network that includes the network node using a session initiation protocol (SIP) via an access network supported by a second core network; and providing, to a second IMS network node, an indication of a single UE SRVCC capability for the UE.

摘要： A method at a sensor module within a sensor system for communicating with a gateway, the method including storing a timing profile for communications with the gateway; waking a radio core of the sensor module at a threshold time prior to a beacon signal being expected from the gateway; sampling a channel for the beacon signal at the radio core; if the beacon signal is detected: waking a processor on the sensor module; exchanging communication with the gateway; and powering down the processor and radio core upon completion of the exchanging communication.

摘要： In some examples, a source device categorizes a plurality of messages for transmission to a recipient device, the plurality of messages comprising vehicle-related information. Based on the categorizing, the source device identifies selected messages of the plurality of messages to be aggregated. The source device aggregates the selected messages into a single transmission from the source device to the recipient device.
