Abstract: Methods and apparatuses for selective harmonic current mitigation pulse width modulation (SHCM-PWM) are provided. Low switching frequencies can be utilized for grid connected cascaded H-bridge multilevel rectifiers to meet harmonic requirements within an extended harmonic spectrum. Instead of using voltage references to calculate switching angles for rectifiers as in conventional selective harmonic elimination-PWM (SHE-PWM) and selective harmonic mitigation-PWM (SHM-PWM), current references can be used to compensate for current harmonics and meet current harmonic requirements and total demand distortion (TDD) within the entire harmonic spectrum.

Abstract: A terminal status subscription method, apparatus, and system. The method includes receiving a notification message sent by a presence server serving a first terminal, acquiring identifiers of N terminals according to the notification message, sending N second subscription messages to a presence server separately serving the N terminals, to separately subscribe to status of the N terminals, receiving a status change notification message that is sent by a presence server serving a second terminal, and sending, according to the status change notification message, a publish message to the presence server serving the first terminal such that the presence server serving the first terminal notifies status of the second terminal of the first terminal, and hence subscription does not need to be separately performed such that subscription to status of multiple terminals of a user is implemented, and user operation complexity is reduced.

Abstract: A user, group, and device management and authentication system allows administrators to manage one or more directories with devices that are not associated with a domain of the one or more directories via a set of APIs. The system also allows applications and services that do not have direct access to a list of directory users to access the one or more directories. The user, group, and device management and authentication system may be an add-on system that works in conjunction with a centrally-managed directory service to provide such functionality. For example, the system may generate an access token associated with a particular directory that can be used by a service accessed by an administrator to call an API provided by the system. The API call may be translated into a directory-specific API call that can be used to perform an action in the particular directory.

Abstract: A method, an apparatus, and a non-transitory computer-readable storage medium used in reloading a mobile number are disclosed. According to some embodiments, in performing the method, the apparatus receives a request of reloading the mobile number. The request is sent by a terminal, but the mobile number does not correspond to the terminal. The apparatus then obtains information on the mobile number, and determines whether the mobile number is a trusted number based on the obtained information. When the mobile number is a trusted number, the apparatus reloads the mobile number. When the mobile number is not a trusted number, the apparatus alerts the terminal that the mobile number is not a trusted number.

Abstract: The present disclosure describes a network entity and a service policy management method that includes: receiving, by a policy and charging rules function entity, a service request sent by an application server; generating a PCC policy and a service chain policy according to the service request; generating a PCC rule and a service chain control rule; and sending the PCC rule and the service chain control rule to a corresponding network rule enforcement device. Both the PCC policy and the service chain policy are managed by a PCRF entity in a 3GPP network. When PCC policy control information and service chain policy control information are transmitted between the application server and a network side, signaling interaction needs to be performed with only the PCRF. Therefore, signaling resources are saved, and network deployment is optimized.
