A shared Radio Network Node, RNN, (102) and a method therein for managing overload in at least one core network (110). The shared RNN is configured to serve a wireless device (104). The wireless device and the shared RNN are operated in a wireless communications network (105) connected to the at least one core network. The shared RNN receives a connection request from the wireless device. The connection request comprises a mapping parameter configured to map to a Mobility Management Entity, MME, (112) comprised in the at least one core network and connected to the shared RNN. The mapping parameter comprises an MME Code, MMEC, which MMEC is uniquely assigned to the MME and to a sharing operator. Further, the shared RNN rejects or redirects the connection request when the MME is overloaded.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
