Communication path switching for mobile devices
First Claim
1. User equipment (UE) comprising:
- logic, at least a portion of which comprises circuitry, to;
exchange second communication path availability information between the UE and another UE, wherein the exchange is to send and receive session initiation protocol (SIP) messages comprising the second communication path availability information over a first communication path;
change a communication session by re-routing traffic flows to the second communication path based on the second communication path availability information;
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;
in response to determining that the UE is outside a proximity services (ProSe) communication path range of the other UE, initiate re-routing of traffic flows back to the first communication path.

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.

14. A mobile terminal configured to:
-
receive a message over an infrastructure communication path comprising an evolved node B (eNB) and an internet protocol multimedia system (IMS), the message comprising direct path availability information for a nearby mobile terminal; and switch communication of one or more traffic flows to a direct communication path based on the direct path availability information, wherein data corresponding to the one or more traffic flows is switched from being communicated over the infrastructure communication path to being communicated over the direct communication path, wherein the one or more traffic flows comprise an existing traffic flow, wherein the data of the existing traffic flow is switched from the first communication path to the second communication path, and wherein switching the one or more traffic flows to the direct communication path comprises substantially simultaneously switching to a direct path address for the mobile terminal and a direct path address for the nearby mobile terminal for the one or more traffic flows. - View Dependent Claims (15, 16, 17, 18)

19. At least one non-transitory computer-readable storage medium having stored thereon instructions that, when executed by a processor, cause the processor to perform operations comprising:
-
determining that a first user equipment (UE) is in sufficient proximity to a second UE for communication over a direct communication path, the first UE and the second UE engaged in internet protocol (IP) multimedia subsystem (IMS) communication over an infrastructure communication path; informing the second UE of the availability of a direct communication path; and re-routing traffic flows from the infrastructure communication path to the direct communication path while maintaining IMS service continuity, wherein the traffic flows comprise an existing traffic flow, wherein the data of the existing traffic flow is switched from the first communication path to the second communication path, wherein the first UE sends to and receives from the second UE data corresponding to a second traffic flow over the first communication path, wherein the existing traffic flow comprises video media packets, and wherein the second traffic flow comprises voice media packets. - View Dependent Claims (20, 21)
