| 7. A method for controlling the flow of data between a radio network controller (RNC) and a base station of a Universal Mobile
Telecommunications Systems (UMTS) mobile communications system with High Speed Downlink Packet Access (HSDPA) capability via
an Iub interface, the method comprising:
sending a message from the RNC towards the base station indicating a total amount of user data waiting in the RNC;
sending a message from the base station towards the RNC granting the amount of data the RNC is allowed to send within a period
of time;
the RNC sending the granted amount of user data information to the base station; and
monitoring information about actual total Iub interface data transport flow, and when a determined Iub interface transport
capacity value is reached, reducing the data transport flow in the Iub interface,
wherein the Iub interface is an interface between the RNC and the base station.
