Recently, these RATs have been used for message splitting in which a message is split into two packet flows, for example, that may enable increased throughput to the (UE). Dynamic mobility management may be provided for the UE by allowing a converged gateway (CGW) to discover the UE. For example, the CGW may identify the UE in communication a first CGW that may be within a first subnet. The CGW may store the identity of the WTRU in the memory. The CGW may transmit the identity of the UE to a second CGW that may be in communication with a second subnet. ## Claims ### Claim at position 1 -38.
