PROACTIVE SEAMLESS SERVICE PROVISIONING IN MOBILE NETWORKS THROUGH TRANSFERRING OF APPLICATION CONTEXT

摘要

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.
