Abstract:
1. Method for sharing load information between radio network controllers connected to a core network by a first standard interface (Iu) and to each other by a second standard interface (Iur) used for facilitating a macrodiversity function where data is sent via multiple Node Bs to a user equipment, said radio network controllers for operating in an environment where the radio network controllers are from a same vendor or from different vendors, comprising the steps of: determining in said first radio network controller over said standard interface a common measurement load value and that a certain type of load condition exists from among a plurality of different types of load conditions indicative of the nature of the type of load condition in said environment where said data is sent via at least one of said multiple Node Bs connected to a first radio network controller and via at least one of said multiple Node Bs connected to a second radio network controller, signaling said second radio network controller over said standard interface that, said certain load condition exists and including a measurement report with said common measurement load value and, in addition, that said certain type of load condition exists with a proposed action using an information element indicative thereof.
