COMMUNICATION PATH SWITCHING FOR MOBILE DEVICES

摘要

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.

主权项

1. User equipment (UE) comprising:
an exchange component configured to exchange second communication path availability information between the UE and another UE, wherein the exchange component sends and receives session initiation protocol (SIP) messages comprising the second communication path availability information over a first communication path; a session component configured to change a communication session by re-routing traffic flows to the second communication path based on the second communication path availability information; and a communication component configured to, in response to changing the communication session, send to and receive from the other UE data corresponding to a first traffic flow over the second communication path, wherein the first traffic flow comprises an existing traffic flow and wherein the data of the existing traffic flow is switched from the first communication path to the second communication path.
