Abstract: Systems, apparatus, and methods for detecting air breathed by a user and/or one or more gases are provided herein. In some embodiments, an apparatus may include a test material adapted to reduce in size when exposed to one or more stimuli. In some embodiments, one or more chemicals may be disposed on the test material and, when exposed to the air breathed by the user, the one or more chemicals are adapted to transform from a first color to a second color. In some embodiments, when the test material reduces in size an intensity of the second color increases. The apparatus may further include a face mask. In this regard, the test material may be removably attached to the face mask. The apparatus may further include a spectrophotometer configured to determine if the one or more chemicals have transformed from the first color to the second color.

Abstract: The disclosure relates to a method and apparatus for determining a communication beam. The method includes receiving, via a user equipment, at least two beams; acquiring beam information of the received beams; selecting a target beam from the received beams based on the beam information; and transmitting information via the target beam.

Abstract: The present disclosure provides a mobility management method and apparatus. The method may include: receiving a plurality of uplink reference signals periodically transmitted by a user equipment; generating network indication information according to variation information of the plurality of uplink reference signals; delivering the network indication information to the user equipment, enabling the user equipment to perform a corresponding operation according to the network indication information and transmit operation information; and performing mobility management on the user equipment according to the operation information transmitted by the user equipment.

Abstract: A method, device and medium for enhancing saturation are provided. The method includes: obtaining image feature information of an image; identifying a type of the image according to the image feature information; selecting a saturation enhancement mode corresponding to the type of the image, and enhancing the saturation of the image using the saturation enhancement mode.

Abstract: A method is provided for identifying an image type. The method includes acquiring a histogram of a channel in a preset color space of an image to be identified, calculating a ratio between a quantity of pixels of a gray-scale value and a quantity of pixels of an adjacent gray-scale value in the channel according to the histogram, and determining a type of the image according to the ratio.

Abstract: A method for a mobile terminal to select a network includes: when the mobile terminal is unable to reside on a top-priority network, recording information of a first cell of the top-priority network that the mobile terminal is unable to reside on, wherein the top-priority network is determined based on a rule preset in the mobile terminal; monitoring an environment for detecting the top-priority network when the mobile terminal is residing on a non-top-priority network; and if a second cell of the top-priority network is detected and a relationship between the detected second cell and the first cell satisfies a preset condition, handing over the mobile terminal to the detected second cell, no matter whether a current network connection state of the mobile terminal is an idle state.

Abstract: A method is provided for establishing a connection to a data service. The method is implemented by a mobile terminal. The method includes, when initiating a first request on a Long Term Evolution (LTE) network for connecting to the data service with a first Access Point Name (APN) preset in the mobile terminal fails, acquiring a second APN. The second APN is assigned to the mobile terminal by the LTE network when the mobile terminal is attached to the LTE network. The method also includes initiating a second request on the LTE network for connecting to the data service with the second APN, to establish the connection to the data service.

Abstract: A network connecting method and apparatus, and a storage medium are provided. The method includes: determining a home network of a terminal and a network mode supported by the terminal; acquiring a historical network connection record corresponding to the network mode, wherein the historical network connection record includes one or more network identities of networks to which the terminal is connected historically; determining whether the home network exists in the historical network connection record based on the network identities; and connecting to a roaming network when the home network does not exist in the historical network connection record.
