Abstract: A method and an apparatus for controlling a carrier frequency in a multi-carrier/cell system are provided. The method includes receiving Channel Quality Indicator (CQI) information of a carrier frequency reported by a terminal, determining whether to deactivate or activate the carrier frequency according to the CQI information, and instructing the terminal to deactivate or activate the carrier frequency according to a result of the determining. Thus, a certain carrier frequency is flexibly activated or deactivated in the multi-carrier/cell system through carrier frequency quality reporting and threshold comparison.

Abstract: Methods and apparatus are provided for controlling activation or deactivation of a carrier frequency in a multi-carrier/cell system. Activation or deactivation of a subsidiary carrier frequency is determined according to a parameter associated with the subsidiary carrier frequency. When the subsidiary carrier frequency is to be activated or deactivated, a message, such as an HS-SCCH order, is transmitted to a terminal to instruct the terminal to activate or deactivate the subsidiary carrier frequency. In this manner, a certain carrier frequency can be flexibly activated or deactivated in accordance with real-time assessment of multi-carrier/cell conditions.

Abstract: A method for managing uplink carrier frequencies is provided, which is applicable to the field of communication. The method includes the following steps: A state switching response message sent by a UE is received, where the state switching response message includes a result of state switching performed by on a secondary uplink carrier serving cell; The result of the state switching is notified to a secondary uplink carrier non-serving cell in a secondary carrier active set through an RNC. A device and a system for managing uplink carrier frequencies are further provided. Through the method, device, and system provided in embodiments of the present invention, the uplink carrier frequencies are managed, so as to facilitate transmission of uplink data during multi-cell collaboration.

Abstract: The present invention provides a method and system for PTZ control. The method comprises: a threshold of a PTZ control mode is preset in a monitor center client, wherein the PTZ control mode includes interlocking and inching; according to the result of comparison between the time for starting the PTZ control and the threshold, the monitor center client sends a command of a PTZ control mode of interlocking or inching to the PTZ. A user presets different thresholds in the monitor center client of a PTZ control system to configure the PTZ control mode, the corresponding PTZ control mode to be used is determined according to behaviors of the user, so that the customized settings of the user are satisfied maximally, and advantages of both interlocking and inching are obtained. In this way, a camera is easy to be positioned in a desired angle, and the efficiency is improved.

Abstract: Scheduling System Information (SI) in a radio communication system is disclosed. System Frame Number (SFN) and position of System Information is determined in accordance with the SFN. The SI-x is established, and all SIs on the radio frames are distributed discretely at different times for sending. An SI scheduling system and a UE are also disclosed. The technical solution under the present invention optimizes scheduling of SI, avoids excessive network load caused by sequentially sending of all SIs on different sub-frames, and improves the efficiency of scheduling user data.
