Abstract  Abstract

Method to facilitate a handover, HO, of an ongoing communication session based on the Internet IP protocol from a first wireless terminal (10; 15) in communication with a first wireless system (19; 25) that uses a first standard of communication and identified by a first internet protocol address to a second wireless terminal (15; 10) configured to communicate with a second wireless system (25; 19) that uses a second communication standard and identified by a second IP address, comprising the method the following steps: the first terminal requests a transfer (S1, S11, S40) of the current IP-based communication session to said second terminal; the first terminal ensures (S15, S16, S42) that the second terminal is on and connected to the second system; connection information (S18, S19, S44) is obtained for the connection of the second terminal to the second system, including an identifier for the second system and the IP address of the second terminal; and the current IP-based communication session is rerouted (S21, S36, S52, S56) from said first terminal to said second terminal in response to obtaining said connection information.
