Managing overload in at least one core network

-14. (canceled)

A shared Radio Network Node, RNN, for managing overload in at least one core network, wherein the shared RNN is configured to serve a wireless device, wherein the wireless device and the shared RNN are operating in a wireless communications network connected to the at least one core network, and wherein the shared RNN comprises a processor and a memory, which memory contains instructions executable by the processor, whereby the shared RNN is operative to:

• receive a connection request from the wireless device, wherein the connection request comprises a mapping parameter configured to map to a Mobility Management Entity, MME, comprised in the at least one core network and connected to the shared RNN, and wherein the mapping parameter comprises an MME Code, MMEC, which MMEC is uniquely assigned to the MME and to a sharing operator;
• and
• reject or redirect the connection request when the MME is overloaded.
