Abstract:
Embodiments of the present invention provide an RCU (remote control unit), an antenna apparatus, an antenna electrical tilting method and an antenna system. The RCU includes a reading device and a driver. The reading device is configured to read, from a memory inside the antenna apparatus, when the antenna apparatus is communicatively connected with the RCU, antenna information of an antenna controlled by the antenna apparatus and configuration data corresponding to the antenna. The antenna information includes the antenna serial number and the antenna model of the antenna. The driver is configured to control the antenna apparatus to adjust an electrical down-tilt angle of the antenna in accordance with the configuration data.

Abstract:
Embodiments of the present invention relate to the network communications field and disclose a method and a device for contacting a contact person, so as to increase probability of contacting the contact person successfully at a single attempt and save user time and the operator's operation resources. The method for contacting the contact person includes: obtaining a current state of the contact person on a communications platform, where the current state indicates a state of the contact person on the communications platform at current time, and the state is determined according to an operation performed by the contact person on the communications platform or a terminal bound to the communications platform; determining a contact manner of the contact person, where the contact manner corresponds to the obtained current state; and setting the determined contact manner as a preferred contact manner of the contact person.
