Abstract: A method is provided for managing load balance in cellular heterogeneous networks. The method comprises: providing a plurality of spectrum carriers for conveying communication signals to/from a macro cell. At least one of the carriers is a shared carrier for conveying communication signals to/from the macro cell and to/from at least one small cell located at the geographical vicinity of the macro cell, and wherein the shared carrier is characterized in that data is the only type of communication signals being conveyed thereat when the cellular network is under congestion. One or more other spectrum carriers are dedicated carriers adapted to essentially convey voice calls, and wherein user terminals are steered away from dedicated carriers to the shared carrier, so that when a data session is initiated for a user terminal camped on the shared carrier, that session will be conveyed one or more of the small cells.
