Transfer of communication sessions between base stations in wireless networks

In a wireless system comprising a plurality of base stations, at least one network gateway, at least one traffic agent and a mobile subscriber terminal currently communicating with a first base stations out of said plurality of base stations communicating with a network gateway and wherein said network gateway conveys Internet Protocol (IP) traffic along a packetized network towards said mobile subscriber terminal, a method to enable carrying out a handover procedure, following which said mobile subscriber terminal which is currently in communication through said first base station will communicate through a second base station out of said plurality of base stations, said method comprising:

• upon initiating a handover procedure, determining that the mobile subscriber terminal will receive all future IP packets addressed thereto via said second base station;
• following the determination that all of said future IP packets should be forwarded to said mobile subscriber terminal via said second base station and prior to establishing a connection between said mobile subscriber terminal and said second base station, forwarding all IP packets being addressed to said mobile subscriber terminal to the second base station, and buffering the received IP packets thereat;
• upon establishing a connection between said mobile subscriber terminal and said second base station, forwarding the IP packets addressed to said mobile subscriber terminal that were forwarded to and buffered at the second base station, to said mobile subscriber terminal, wherein said buffered IP packets are delivered to said mobile subscriber terminal before delivering any packets addressed thereto along a new path extending between a network gateway and the second base station which does not extend via the first base station.
