Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device, and a data processing method and device. Background technique [0002] With the development of the mobile Internet and the popularization of smart phones, the demand for mobile data traffic is increasing rapidly, and the rapid growth of data services poses a severe challenge to the transmission capacity of mobile communication networks. According to the forecast of relevant agencies, in the next ten years (2011-2020), the mobile data business volume will double every year, and will increase by a thousand times in ten years. [0003] Most mobile data services mainly occur indoors and hotspot environments, which are reflected in nomadic / local wireless access scenarios. According to statistics, nearly 70% of the current mobile data traffic takes place indoors, and this proportion will continue to grow, and it is expected that by 2012 it will...
