Abstract: The present disclosure describes how a master beacon having a known UUID can be used to capture beacons within its range and superimpose a systematic address scheme on those beacons. The superimposed address scheme can then be used as a proxy for the individual beacons when developing applications that make use of the beacons. A master beacon automatically detects each beacon in a plurality of beacons and, for a set of beacons in the plurality of beacons, automatically changes either the first profile identifier or the second profile identifier for each beacon in the set of beacons. The change is such that the first profile identifier or the second profile identifier is identical for each beacon in the set of beacons and is also associated with the master beacon.

Abstract: Embodiments of this application provide a method for selecting a network, applied to an electronic device, the method including: receiving a redirect message, where the redirect message carries information about a first frequency: selecting, based on a signal parameter of the first frequency and a signal parameter of a prior frequency, a target frequency from the first frequency and the prior frequency; and redirecting to a cell at the target frequency. It can be seen that after receiving the redirect message, the electronic device selects, based on the signal parameter of the frequency carried in the redirect message and the signal parameter of the prior frequency, the target frequency to be redirected to. Compared with a manner of redirecting to a cell at the frequency carried in the redirect message, the method is more conducive to selecting a frequency at which a signal is better, and further redirecting to a network in which a signal is better.
