1. A method for flow control in a base station, comprising:

  • transmitting an initial flow indication message indicating an initial window size that defines an initial amount of space available in a buffer of the base station for receiving data from a base station controller, wherein the initial flow indication message is transmitted when a connection is made between the base station and the base station controller;

    determining whether a threshold time interval has elapsed since the initial flow indication message was transmitted from the base station;

    determining that a data packet is wirelessly transmitted from the buffer of the base station to a mobile unit;

    incrementing, at the base station, a flow indication counter when the data packet is wirelessly transmitted from the buffer of the base station to the mobile unit, wherein the flow indication counter indicates a number of data packets transmitted out of the buffer;

    determining whether the flow indication counter is greater than or equal to a threshold number;

    generating an updated flow indication message when the flow indication counter is greater than or equal to the threshold number and when the threshold time interval has elapsed; and

    transmitting the updated flow indication message to the base station controller.
