Patent ID: 10687264

Abstract:
In one example, a method and apparatus for providing Internet protocol (IP) packet flow mobility from a first wireless access technology (RAT) interface to a second wireless access technology (RAT) interface communicates packet information of a first IP packet flow via the first RAT interface and transmits a redirection packet for the first IP packet flow via the second RAT interface during the communication of the packet information. The method and apparatus also transmits redirected packet information of the first IP packet flow to the second RAT interface in response to the receiving of redirected packet information of the first IP packet flow from the second RAT interface. In one example, a method and apparatus may receive redirected packet information of the first IP packet flow from the second RAT interface in response to the transmitting of the redirection packet. This operation may be carried out, for example, in a UE. However, a network gateway may also initiate the redirection operation if desired.
