[0084] According to the first embodiment, the connection change (that is, handover or movement) of the mobile entity from the first network access entity to the second network access entity is performed, so that the mobile entity sends to the second network an A message of the information of the incoming entity, the message enables the second network entity to obtain the global address of the first network entity. That is, when the global address of the first network access entity is necessary to complete the handover, and the mobile entity (such as a mobile IPv6 mobile node MN) does not know this global address, the mobile node sends a message corresponding to the second network entity to the second network entity. Known information associated with a network access entity. By using this information, the second network entity is able to obtain the global address of the first network access entity so that the handover or mobility procedure can be completed.

Abstract

A method for performing a change of a connection of a mobile entity from a first network access entity to a second network access entity, wherein a global address of the first network access entity is not known to the mobile entity is provided. According to one embodiment, the method includes the step of sending a message including information for identifying the first network access entity from the mobile entity to the second network access entity which enables the second network entity to direct traffic to the first network entity. According to another embodiment, the invention also provides a method for the reverse direction. Namely, the invention provides a method for sending IP signaling from the mobile entity or from the first network access entity towards the second network access entity, whose global IP address is not known by the mobile entity or first network access entity.

Description

technical field [0001] The present invention relates to a method and system for handover of a mobile entity between two network access entities where the global address of one or both participating network access entities is not known to the mobile entity performing the handover Connection. Background technique [0002] The present invention relates to mobile IP networks, and more particularly to performing a handover or movement from one access router to another. [0003] The field of the invention relates to optimized IP layer handover for seamless session mobility (ie, optimization for Mobile IPv6). More specifically, the present invention is mainly applicable to seamless session continuity during inter-system handover or supplementary access IP layer handover (for example, seamless session continuity between WLAN and 3GPP systems, such as 3GPP TR22.934 "Feasibility study on 3GPP system to Wireless Local AreaNetwork (WLAN) interworking"). [0004] The IETF (Internet En...
