Title: Mobile ip registration in selected inter-pdsn dormant handoff cases in a cdma2000-based cellular telecommunicating network
Inventor: SHAFIK KARIM
IPC: H04B7/216
Filed: 2001-05-08
Granted: 2006-07-25
Abstract: In a cellular telecommunications network, a method and system for performing dormant hand-off for a dormant Mobile Node (MN) between a source packet zone an a target packet zone, when the MN still has an active A10 and Point-to Point ~ Protocol (PPP) connection in the target packet zone. According to the method, when handed-off, the MN issues an origination request with a Data Ready to Sent (DRS) parameter set to zero for the target Base Station Controller (BSC-T) which responsive to the request further sends an A9-setup-A8 registration request to a target Packet Control Function (PCF-T). The PCF-T then sends an A-11 Registration Request message to a Packet Data Service Node (PDSN-T) of the target packet zone. Responsive to the receipt of the Registration request, the PDSN-T sends an agent advertisement message to the MN and initiates the Mobile IP (MIP) registration procedure, and the MN can register the care-of address information relating to the new serving PDSN, the PDSN-T, with its Home Agent (HA). According to another embodiment, the same method is to be used for performing a hand-off of the dormant MN to the target packet zone, when the MN, before issuing the origination request, demands the activation of a packet data session.

Abstract: A method and system for use in freeform modeling of solids and surfaces in which multiple commands for modifying the geometry of an object can be designated to run concurrently, so as to greatly reduce the number of steps required of the user in the design process. The method and system also allows commands to be designated as associative, so that the command is performed automatically whenever the geometry to which it is attached is modified. This leads to a further streamlining of the design process. The method and system also allows the user to store the interactive scene as it is at any given time, with the current selections and tool representations, so that the work can be resumed later without the user having to redo any interactions. With that, and in relation to parallel and associative commands, the system allows the user to capture all design constraints and dependencies throughout the whole lifetime of a design model.
