Abstract
Methods, systems, and devices for switching internet protocol (IP) flows from a first communication path to a second communication path are disclosed herein. A user equipment (UE) may include an exchange component, a session component, and a communication component. The exchange component exchanges second communication path availability information between the UE and another UE by sending and receiving session initiation protocol (SIP) messages that include second communication path availability information over the first communication path. The session component changes the communication session by re-routing traffic flows to the second communication path based on the exchanged second path availability information. The communication component sends to and receives from the other UE data corresponding to an IP flow over the second communication path.
