Abstract: A method for providing a restricted service and a communications device, where the method includes: receiving, by a policy control function (PCF), an identifier of a terminal and indication information, where the indication information is used to indicate that the terminal is in a state of exception or indicate an exception type of the terminal; and sending, by the PCF, the identifier of the terminal and a first restricted service policy according to the indication information, where the first restricted service policy is used to provide a restricted service for the terminal.

Abstract: The disclosed principles provide wearable body sensor systems and related methods to evaluate the whole body movement with or without an assistive walking device. More specifically, the disclosed principles monitor the whole body movement including COG & BOS with a 3-dimensional (3D) mapping over a given period of time. The disclosed principles provide a number of objectives, which include providing a wearable body 3D sensor network that can constantly monitor change of COG over the BOS during daily mobility; to clinically evaluate older adults in maintaining upright posture and prevent falls in senior living communities; and to clinically establish a quantitative mathematical model to determine the stability of the older adults.
