Abstract
Methods and systems for reconfiguring communications systems are provided. A communications system comprises one or more radio head interface modules and a call processing software module. The one or more radio head interface modules are adapted to communicate with the call processing software module. The call processing software module performs modulation and demodulation of voice and data streams using one or more air interface standards. The one or more radio head interface modules receive reconfiguration parameters from the call processing software module for one or more logical channels. The call processing software module and the one or more radio head interface modules communicate one or more pages of data samples to each other, each of the one or more pages of data samples having a page header. Reconfiguration parameters are contained in the page header.
