摘要： A device includes a link layer configured to use a first link layer address and a second link layer address, maintain the first link layer address unchanged for a duration of an association of the device with a wireless network, and change the second link layer address from a first value to a second value during the duration.

摘要： In some examples, an access point (AP) receives, from a wireless device during a pre-associated state between the AP and the wireless device, a request, a first value, and an encrypted version of the first value. The AP sends, to the wireless device during the pre-associated state, an encrypted version of a second value relating to an encryption key that is based on the first value, and a response to the request, the response encrypted using the encryption key.

摘要： A method of selecting a cellular network entails detecting a Wi-Fi signal, obtaining a country code from the Wi-Fi signal, prioritizing cellular network frequency bands based on the country code to define a band priority, and selecting a cellular network based on the band priority. The country code may be an IEEE 802.11d Country Code Information Element.

摘要： In some implementations, a power saving method includes receiving, from a base station, at a user equipment (UE), a Discontinuous Reception (DRX) configuration. The UE determines a WLAN listen interval that includes at least one Traffic Indication Map (TIM) period and at least one TIM transmission period. The UE selects, based on the DRX configuration, a TIM message to monitor within an associated TIM transmission period from the at least one TIM transmission period in the listen interval. The UE determines a WLAN wakeup time that overlaps the associated TIM transmission period. During the associated TIM transmission periods, the UE receives, from an Access Point (AP), the selected TIM message.

摘要： In some examples, an electronic device receives configuration information relating to network connectivity with a network of a vehicle, the configuration information including a credential. The electronic device establishes, using the configuration information, a connection with the network of the vehicle to access a service, and revokes the credential in response to a termination of the access of the service.

摘要： A method at a computing device within an Intelligent Transportation System, the method comprising: determining, at the computing device, whether a short-term certificate is available to sign a message; if the short-term certificate is available, signing the message with a private key associated with the short-term certificate; if the short-term certificate is not available, signing the message with a private key associated with a long-term certificate; and sending the message to a recipient.

摘要： A method at a gateway (110, 510; 810) within a sensor system (210; 212; 214) for communicating with at least one sensor module (160; 512, 812) comprises: storing a timing profile for communications with the at least one sensor module; powering down a processor of the gateway; waking (720) a radio core of the gateway at a threshold time prior to a transmission time for a sensor beacon signal from the at least one sensor module; and sampling (822) a channel for the sensor beacon signal at the radio core while the processor of the gateway is powered down. If the sensor beacon signal is detected: the processor (120) on the gateway (110) is awakened; communication is exchanged with the at least one sensor module (160); a report is provided to a network server; and the processor and radio core is powered down (752) upon completion of the exchanging communication.
