HANDOVER METHOD AND MOBILE TERMINAL AND HOME AGENT USED IN THE METHOD |
摘要 |
<p>Disclosed is a technique to provide a handover method that can improve the communication efficiency by reducing tunnel overhead between a mobile node and a home agent. When the mobile node (UE) (107) performs handover (HO) from a first access router (104) to a second access router (105) and if the IP versions supported by the networks before and after the HO are different, the UE transmits a first message including an allocation request for a home address of the HO target to the home agent (HA) and a second message including an address allocation request. The HA transmits to the UE, a third message including the home address of the HO target based on the allocation request and transmits to the UE, a fourth message including the home address based on the address allocation request.</p> |
