Abstract
A method, device management server, Packet Data Network Gateway (PDN GW) and User Equipment (UE) for establishing a PDN connection having defined packet flow limitations from a UE to a PDN GW. When a misbehaving or malicious UE is operating in the Evolved Packet System (EPS), the invention enables the UE to retain a PDN connection with an EPS bearer open until the software in the UE has been updated. The server sends to the UE, a management object that includes a logic parameter (packet filters) for controlling a packet flow from the UE to the network, or a defined Access Point Name (APN) that enables the UE to obtain the packet filters from a PDN GW. In turn, the UE sends to the network, a request for a new PDN connection while requesting deactivation of any previously existing PDN connections. The UE transmits on the new PDN connection, only packets allowed by the logic parameter.
