Abstract
Methods and apparatuses are provided that facilitate detaching one of a plurality of network connections to ensure state information is retained at one or more network nodes. For a device initiated detach, the device can transmit a handover message related to performing a handover of one network connection to another active network connection, as opposed to explicitly detaching the network connection. This can cause at least some state information, such as a gateway identifier, to be retained in one or more network nodes. For a network initiated detach, a gateway can provision state information to a state information server following receiving a routing tunnel termination message to ensure state information deleted as a part of the detach is re-provisioned to the state information server.
