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.
