A control plane load in a mobile network is managed. The mobile network includes a radio access network having a base station adapted for connecting to a plurality of user equipments (UEs) over a radio interface, and a core network (CN). The RAN determines a RAN control plane load, and transmits an information indicative of the RAN control plane load over a mobility management server to a policy server of the CN to initiate a traffic management in the CN based on the RAN control plane load. Related base stations, mobility management servers, and policy servers are disclosed.
