Abstract
Abstract A wireless communication system selectively delays serviced data communications to produce a desired level of voice communications capacity. The system first determines whether the wireless communication system has sufficient voice communications capacity. If it is determined that the wireless communication system has insufficient voice communications capacity, the system determines a data communications delay that is required to provide sufficient voice communications capacity. Based upon its determination, the system then selectively delays some or all of the data communications to create the sufficient voice communications capacity. In one operation, one data communication serviced by the wireless communication system is selectively delayed to create the sufficient voice communications capacity. In another operation, a plurality of data communications serviced by the wireless communication system are selectively delayed to create the sufficient voice communications capacity. When a plurality of data communications being serviced by the wireless communication system, some of the plurality of the data communications serviced by the wireless communication system are delayed by a first delay level and other of the data communications serviced are delayed by a second delay level.
