1. A method for securing radio connections, comprising:
performing a connection setup with a user equipment (UE) to configure a connection that does not already have a secure connection established;
prior to securing the connection, determining that security information is needed for the UE based on an event which triggers a need of the security information;
sending an indication to a network node to request the security information for the UE; and
receiving the security information from the network node via a UE context setup procedure.
