Abstract: Systems and methods for automatically modifying computing devices are provided. Various embodiments allow multiple control beacons (e.g., Bluetooth low energy beacons) with GPS to automatically pre-configure by discovering each other using location provided by the GPS in the beacons. These beacons can then be used to enforce multiple rules or policies on the computing device (e.g., restrict the activities/functionality of a mobile device). For example, a beacon can be installed at a family's dinner table and can be used as a trigger to restrict (or activate) phone features (e.g., allow only incoming calls while near this beacon during dinner times). In some embodiments, the GPS on the beacon can be used to notify administrators (e.g., parents) if the beacon is moved from its current location.

Abstract: Provided is a method for a terminal for measuring the reference signal received quality (RSRQ) of a serving cell. The terminal receives a discovery reference signal (DRS) measurement timing configuration (DMTC) from a network, and on the basis of the received DMTC, the terminal can measure the RSRQ of the serving cell. The serving cell may comprise a small cell supporting a DRS, and the small cell may be present on the same frequency as the serving cell. Furthermore, the RSRQ measurement of the serving cell can only be carried out during a non-DMTC period set in accordance with the DMTC. The non-DMTC period is a period during which a DRS is not transmitted from the small cell.
