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.

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 semi-insulating silicon carbide monocrystal and a method of growing the same are disclosed. The semi-insulating silicon carbide monocrystal comprises intrinsic impurities, deep energy level dopants and intrinsic point defects. The intrinsic impurities are introduced unintentionally during manufacture of the silicon carbide monocrystal, and the deep energy level dopants and the intrinsic point defects are doped or introduced intentionally to compensate for the intrinsic impurities. The intrinsic impurities include shallow energy level donor impurities and shallow energy level acceptor impurities. A sum of a concentration of the deep energy level dopants and a concentration of the intrinsic point defects is greater than a difference between a concentration of the shallow energy level donor impurities and a concentration of the shallow energy level acceptor impurities, and the concentration of the intrinsic point defects is less than the concentration of the deep energy level dopants. The semi-insulating SiC monocrystal has resistivity greater than 1×105 Ω·cm at room temperature, and its electrical performances and crystal quality satisfy requirements for manufacture of microwave devices. The deep energy level dopants and the intrinsic point defects jointly serve to compensate the intrinsic impurities, so as to obtain a high quality semi-insulating single crystal.
