Proactive seamless service provisioning in mobile networks through transferring of application context
First Claim
1. A method for supporting relocation of an Internet Protocol session during a network layer handover in a mobile communication system, the method comprising:
- sending application context information from a first device to a second device, the application context information indicating activities to be executed pro-actively before a network layer handover and including a requested communication requirement, wherein the application context information includes information on a current state of the Internet Protocol session and facilitates the relocation of the Internet Protocol session;
receiving a first message from the second device at the first device, the first message including a first indicator indicating whether or not the second device can satisfy the requested communication requirement;
in response to the first indicator indicating that the second device cannot satisfy the requested communication requirement, sending the application context information from the first device to a third device and receiving a second message from the third device at the first device, the second message including a second indicator indicating whether or not the third device can satisfy the requested communication requirement; and
in response to the second indicator indicating that the third device can satisfy the requested communication requirement, selecting the third device as a target access router for the network layer handover.

Abstract
A method supporting relocation of an Internet Protocol session during a network layer handover is provided. Application context information is sent to a device. The application context information indicates activities to be executed pro-actively before a network layer handover and includes a requested communication requirement. A first message is received from the device that includes a first indicator indicating whether or not the device can satisfy the requested communication requirement. If the first indicator indicates that the device cannot satisfy the requested communication requirement, the application context information is sent to another device, and a second message is received from the other device. The second message includes a second indicator indicating whether or not the other device can satisfy the requested communication requirement. If the second indicator indicates that the other device can satisfy the requested communication requirement, the other device is selected as a target access router for the network layer handover.

21. A device comprising:
-
an output interface configured to send application context information to a second device, the application context information indicating activities to be executed pro-actively before a network layer handover and including a requested communication requirement, wherein the application context information includes information on a current state of an Internet Protocol session and facilitates relocation of the Internet Protocol session; an input interface configured to; receive a first message from the second device, the first message including a first indicator indicating whether or not the second device can satisfy the requested communication requirement; and a processor operably coupled to the output interface and the input interface and configured to execute a computer-readable program configured to cause the device, in response to the first indicator indicating that the second device cannot satisfy the requested communication requirement, to send the application context information to a third device, the second message including a second indicator indicating whether or not the third device can satisfy the requested communication requirement; wherein the input interface is further configured to receive a second message from the third device, the second message including a second indicator indicating whether or not the third device can satisfy the requested communication requirement; and wherein the processor is further configured to select the third device as a target access router for the network layer handover in response to the second indicator indicating that the third device can satisfy the requested communication requirement.

22. A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising:
-
instructions to send application context information to a second device, the application context information indicating activities to be executed pro-actively before a network layer handover and including a requested communication requirement, wherein the application context information includes information on a current state of an Internet Protocol session and facilitates relocation of the Internet Protocol session; instructions to receive a first message from the second device, the first message including a first indicator indicating whether or not the second device can satisfy the requested communication requirement; instructions to, in response to the first indicator indicating that the second device cannot satisfy the requested communication requirement, send the application context information to a third device and process a second message received from the third device, the second message including a second indicator indicating whether or not the third device can satisfy the requested communication requirement; and instructions to, in response to the second indicator indicating that the third device can satisfy the requested communication requirement, select the third device as a target access router for the network layer handover.
