System and Method for Communications Device and Network Component Operation
First Claim
1. A method for operating a control node, the method comprising:
- receiving a locator update request indicating that a user equipment (UE) has migrated from a previous access node (AN) to a new AN;
retrieving a user information indicating that the UE was assigned a locator identifier (ID) upon attachment to the previous AN, and further indicating that a UE has been assigned an original host session identifier (ID) that uniquely identifies a communications session of the UE;
sending a request message to a gateway; and
receiving a response message from the gateway indicating that the UE has been assigned a new locator ID without being assigned a new host session ID such that the original host session ID remains assigned to the UE.

Abstract
A system and method for communications device and network component operation in an ID/Locator Split Based heterogeneous network is provided. A method for control node operation includes receiving an attach request, and attempting to authenticate/authorize the communications node. The attach request is a request from a communications node to attach to a heterogeneous network. The method also includes if the communications node authenticated/authorized successfully, causing an identification and a location to be assigned for the communications node, completing an attachment for the communications node, and transmitting information to the communications node. The method further includes if the communications node did not authenticate/authorize successfully, sending an attach reject message to the communications node. The identification and the location are separate values.

6. A control node comprising:
-
a processor; and a computer readable storage medium storing programming for execution by the processor, the programming including instructions to; receive a locator update request indicating that a user equipment (UE) has migrated from a previous access node (AN) to a new AN; retrieve a user information indicating that the UE was assigned an original locator identifier (ID) upon attachment to the previous AN, and further indicating that a UE has been assigned an original host session identifier (ID); send a request message to a gateway; and receive a response message from the gateway indicating that the UE has been assigned a new locator ID without being assigned a new host session ID such that the original host session ID remains assigned to the UE. - View Dependent Claims (7, 8, 9, 10, 11)

12. A control node comprising:
-
a processor; and a computer readable storage medium storing programming for execution by the processor, the programming including instructions to; receive an attach request message requesting attachment of a user equipment (UE) o a new access node (AN), wherein the UE is associated with an original locator identifier (ID) and an original host session identifier (ID) prior to completion of the requested attachment; send a bearer request message to a gateway; receive a bearer response message from the gateway indicating assignment of a new locator ID to the UE for use after completion of the requested attachment; and complete the requested attachment of the UE, wherein the original host session ID remains assigned to the UE after the requested attachment is complete. - View Dependent Claims (13, 14, 15, 16, 17)

18. A gateway in a heterogeneous network, the gateway comprising:
-
a processor; and a computer readable storage medium storing programming for execution by the processor, the programming including instructions to; receive a bearer request message indicating that a user equipment (UE) attached a previous Access Node (AN) in the heterogeneous network is requesting attachment to a new AN in the heterogeneous network, wherein an original host session identifier (ID) is associated with an original locater ID prior to completion of the requested attachment; and assign a new locator identifier (ID) to the UE for use after completion of the requested attachment, wherein the original host session ID remains assigned to the UE after completion of the requested attachment. - View Dependent Claims (19, 20, 21, 22)
