Abstract
A method for dynamically varying the allocation and distribution of a base station's resources in response to fluctuations in demand for services. The method includes transmitting a status signal from a base station to a base station controller over an Iub interface. The status signal may correspond to the demand of the base station's transmit power for a data transmission service, such as HSDPA, and for at least another service, such as a dedicated voice channel. In response to receiving the usage information signal, the base station controller may vary the transmit power of the base station allocated for HSDPA and/or for the dedicated voice, data and/or both integrated voice and data channel. In response to receiving users' status information for HSDPA services, the base station controller may vary its call admission status for HSDPA and/or dedicated voice, data and/or both integrated voice and data users.
