System and method for controlling data flow in a wireless network connection

摘要

A system and method for controlling the flow of data from a data network to a mobile user over a wireless link. A data flow controller is provided in an inter-working gateway between the mobile switch center of the wireless network and the data network. The data flow controller determines the amount of available space in the mobile switch center buffer and ensures that the amount of data sent to the mobile switch center is no greater than the available buffer space. The data flow controller continually updates the available buffer space by determining the amount of data sent periodically to the mobile user according to a given airlink data rate. The data flow controller includes a buffer to store any remaining data that could not be sent to avoid overflowing the mobile switch center buffer.
