Abstract
A method and devices are provided to enable continuing a communication session currently carried by a mobile subscriber station (MSS) while switching from a first base station to a second base station. During the communication session that is being held with the MSS, a first Internet Protocol (IP) datagram is selected from among a plurality of IP datagrams associated with that communication session and received at a network gateway adapted to convey IP traffic received from the MSS. Following that selection and prior to establishing a connection between the mobile subscriber terminal and the second base station, IP datagrams that will be received at that network gateway after that first IP datagram had been received and which are addressed to the MSS, are backed up. Upon establishing a connection between the MSS and the second base station, the IP datagrams that were backed up are forwarded to the MSS, and all further IP datagrams which are addressed to the MSS and received at that network gateway after establishing the connection between the MSS and the second base station, will be forwarded to the MSS through the second base station.
