Title: Method of lossless mobile ip packet delivery and system thereof
Inventor: JEONG HAN YOU
IPC: H04L12/66
Filed: 2007-02-12
Abstract: A lossless mobile IP packet delivery method and a system thereof are provided to deliver IP packets to an MS(Mobile Station) without any loss by delivering IP packets, stored in the buffer of an old ACR(Access Control Router) and the buffer of an old RAS(Radio Access Station), to a new RAS through the creation of a tunnel in case that the MS performs handover to the new RAS. An MS starts a handover procedure in the case of moving from an old RAS belonging to an old ACR to a new RAS belonging to a new ACR(S601). If a signal sent from the old RAS is below a specific threshold, the MS transmits a MOV_HO-IND message to the old RAS(S602). At this moment, the MS disconnects the association with the old RAS and the old ACR(S603). The old RAS stores IP packets, not delivered to the MS, in its own buffer manager the moment the MOV_HO-IND message is received(S604). Also the old ACR stores packets, which will be delivered to the MS from a CN(Correspondent Node), in its buffer manager(S605). The MS transmits an RNG-REQ message to the new RAS and establishes a new connection(S606). The old RAS and the new RAS carry out a link layer handover procedure in accordance with IEEE 802.16e and WiMAX NWG Stage documents(S607). The MS acquires a CoA(Care of Address) through an agent searching procedure defined in mobile IP protocol(S608). The old RAS creates a tunnel with the new RAS while executing the link layer handover procedure, and transmits the stored IP packets to the new RAS through the tunnel if the agent searching procedure is completed(S609).
