Claim Text:
1. A method of managing traffic load in a first radiocommunication network comprising a core network including primary and secondary nodes and a radio access network including radio controllers, each primary node connecting at least one secondary node and each secondary node connecting at least one radio controller via respective links, the method comprising the following steps in relation to a given primary node: calculating, with at least one entity in said first radio communication network, respective target core network load reduction values for the links connecting the given primary node and secondary nodes, depending on a value at which a current load of the given primary node exceeds a first primary node load threshold; calculating, with the at least one entity in said first radio communication network, respective target radio access network load reduction values for the links connecting said secondary nodes, which are connected to the given primary node, and said radio controllers, depending on calculated target core network load reduction values; and taking actions, with the at least one entity in said first radio communication network, to change traffic distribution in the radiocommunication network by taking account of at least some of the calculated target radio access network load reduction values.
