A method and a system for controlling handoff of a terminal

摘要

The invention relates to a method for controlling handoff taking place in a wireless data transfer network, where the traffic coming to the terminal is routed to the home network of the terminal. The home network knows the foreign network where the terminal belonging to the home network is at each time located. The traffic coming to the home network is directed further to the foreign network to be transmitted to the terminal. The foreign agent discovery performed in order to determine the location of the terminal as well as the registration for the foreign agent in question is performed in the method as one procedure, in which case a smaller number of message exchanges is reached compared to before. In addition, the invention relates to a system implementing the method. <IMAGE> <IMAGE> <IMAGE>
