摘要： A variable-frequency bus adapter, a variable-frequency bus adapting method and a variable-frequency bus adapting system are provided. The method includes: generating a bus blocking indication according to a dynamic frequency scaling (DFS) request signal sent by a bus side; blocking a current bus transfer according to the bus blocking indication; and feeding back a DFS response signal to the bus side after blocking the current bus transfer, where the DFS response signal is adapted to enable the bus side to perform a DFS operation. In the method, the bus transfer is temporarily blocked during the DFS, so that undesired influence on peripheral components caused by unstable bus block during the bus DFS is reduced without increasing the number of clock domains of the system or modifying the peripheral components, thus reducing the complexity of the implementation of the system, and improving the applicability of dynamic voltage frequency scaling (DVFS).

摘要： A method and apparatus for adaptively controlling the audio output (122) of a communication device (114) according to the noise characteristics of the receiver listening environment (119). An output volume for the communication device (114) is set by a user (e.g., listener 118). The communication device (114) can intermittently sample ambient noise (116) of its environment (119). A minimum signal to noise threshold can be established for audio output (122). A total adjustment for the audio output (122) is established based on the ambient noise (116), the user set output volume, and the minimum signal to noise threshold. The total adjustment is a product of a software volume adjustment (230) and a hardware gain adjustment (240). The software volume adjustment (230) and the hardware gain adjustment (240) is adaptively applied when the communication device (114) outputs audio (122).

摘要： A load balancing method and system is provided. When a terminal enters an idle, access or service state, and a base station determines that the terminal is in a multi-band covering section, load conditions of the bands in the section are recorded; and when determining that a preset idle or access or service state condition is met based on the recorded load conditions of the bands in the section, the base station performs load balancing control on the terminal. For the terminal in the idle, access or service state, load balancing for a multi-band network can be implemented.
