System and method for handover of an access terminal in a communication network
First Claim
1. A system for implementing handover of a mobile Internet Protocol (IP) session in a communication network, comprising:
- a memory operable to store at least one context information rule associated with an access terminal; and
a processor operable to;
receive a registration request message from a target radio network controller;
in response to receipt of the registration request message, transmit a context information request message to an anchor IP gateway with a connection to an anchor radio network controller;
receive a context information response message from the anchor IP gateway, the anchor IP gateway waiting for an idle signal condition before releasing the connection to the anchor radio network controller, the context information response message including an authorization rule and the at least one context information rule;
apply the context information rule to the mobile IP by authenticating an access terminal without accessing information from a designated home network;
buffer a first packet from a correspondent node communicating with the access terminal; and
enforce the authorization rule of the context information on the first packet.

Abstract
In one embodiment according to the present disclosure, a system for implementing handover of a mobile IP session in a cellular communication network generally includes a processor and a memory for storing one or more context information rules associated with an access terminal. The processor is operable to receive a registration request message from the target radio network controller and in response to receipt of the registration request message, transmit a context information request message to query context information from an anchor IP gateway. The processor is also operable to receive a context information response message from the anchor IP gateway and apply the context information response message to the mobile IP connection. The context information response message including at least one context information rule that is associated with the access terminal.

6. A method for implementing handover of a mobile Internet Protocol (IP) session in a communication network, comprising:
-
receiving a registration request message from a target radio network controller; in response to receipt of the registration request message, transmitting a context information request message to an anchor IP gateway with a connection to an anchor radio network controller, the context information being associated with an access terminal; receiving a context information response message from an anchor IP gateway, the anchor IP gateway waiting for an idle signal condition before releasing the connection to the anchor radio network controller, the context information response message including an authorization rule and the at least one context information rule; applying the context information rule to a mobile IP connection by authenticating an access terminal without accessing information from a designated home network; buffering a first packet from a correspondent node communicating with the access terminal; and enforcing the authorization rule of the context information on the first packet. - View Dependent Claims (7, 8, 9)

10. A non-transitory computer-readable storage medium encoded with logic for implementing handover of a mobile Internet Protocol (IP) session in a communication network, the logic operable to:
-
receive a registration request message from a target radio network controller; in response to receipt of the registration request message, transmit a context information request message to an anchor IP gateway with a connection to an anchor radio network controller, the context information being associated with an access terminal; receive a context information response message from the anchor IP gateway, the anchor IP gateway waiting for an idle signal condition before releasing the connection to the anchor radio network controller, the context information response message including an authorization rule and the at least one context information rule; apply the context information rule to the mobile IP connection by authenticating an access terminal without accessing information from a designated home network; buffer a first packet from a correspondent node communicating with the access terminal; and enforce the authorization rule of the context information on the first packet. - View Dependent Claims (11, 12, 13, 14)

15. A system for implementing handover of a mobile Internet Protocol (IP) session in a communication network, comprising:
-
means for receiving a registration request message from a target radio network controller; in response to receipt of the registration request message, means for transmitting a context information request message to an anchor IP gateway with a connection to an anchor radio network controller, the context information being associated with an access terminal; means for receiving a context information response message from an anchor IP gateway, the anchor IP gateway waiting for an idle signal condition before releasing the connection to the anchor radio network controller, the context information response message including an authorization rule and the at least one context information rule; means for applying the context information rule to a mobile IP by authenticating an access terminal without accessing information from a designated home network; means for buffering a first packet from a correspondent node communicating with the access terminal; and means for enforcing the authorization rule of the context information on the first packet.
