Abstract: 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.

Abstract: A method and device for locating voice transmission problems are provided. The method includes: configuring a data transmitting/receiving statistics module at each transmission stage of a media stream to perform statistics on data transmitting/receiving of the transmission stage; the data transmitting/receiving statistics module reporting data after statistics to a preset data analysis module; and the data analysis module locating the voice transmission problems after analyzing the data reported by the data transmitting/receiving statistics module. The device includes the data transmitting/receiving statistics module and the data analysis module. The method and device can automatically detect the voice transmission problems such as getting through in one-way, discontinuous, etc.
