Abstract: Surrogates for roadside objects can be used for vehicle testing. A grass surrogate can be configured to exhibit substantially the same characteristics as natural grass when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle systems (e.g., a road departure mitigation system). The grass surrogate can help a vehicle to identify road boundaries, particularly in portions of a road that do not include lane markings. The grass surrogate can be configured to withstand being driven over by a test vehicle without being damaged and/or without damaging the test vehicle. In some arrangements, the grass surrogate can include artificial grass that is coated with a mixture of high gloss acrylic paint and high reflectance pigments.

Abstract: Embodiments of the present invention disclose a subscription information download method, a related device, and a system. The method includes: receiving, by a first network device, a first request, where the first request is sent by a terminal after connecting to and attaching to a first network when the terminal has no effective profile, and is used to request to establish a network connection for downloading a profile; establishing, by the first network device, the network connection used for downloading the profile; and returning a response message for the first request to the terminal device, to inform the terminal device that the network connection has been successfully established.

Abstract: Embodiments of this application relate to a method and a device for protecting privacy. The method includes: sending, by a remote terminal, a first message to a mobility management entity by using a relay terminal, where the first message includes first identity information of the remote terminal, and the first message is used by the mobility management entity to obtain an international mobile subscriber identity IMSI of the remote terminal based on the first identity information of the remote terminal, where the first identity information is a proximity service relay user key identity PRUK ID. Because the first identity information is used to replace the IMSI, interception of the IMSI by the relay terminal is avoided, and user privacy is protected.

Abstract: Surrogates for roadside objects, such as metal guardrails, can be used for vehicle testing. A surrogate for a metal guardrail can have substantially the same size and/or shape as the metal guardrail that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart metal guardrail when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle system (e.g., a road departure mitigation system). The surrogates can be configured to withstand being crashed into by a test vehicle without being damaged and without damaging the test vehicle.
