Abstract:
The invention provides a method for assisting handover of a communication session associated with a UT from a first radio access point, AP1, to a second radio access point, AP2, in a radio access network, said method to be carried out by said AP1 and comprising the steps of:—receiving a handover intention notify message comprising a session identifier identifying said session and indicating that said UT intends to perform a session handover,—assigning said session a buffer memory space in a memory of said AP1,—buffering downlink data packets addressed to said UT in said buffer memory as a response on receiving said handover intention notify message. The invention further provides a UT, an AP1, AP2, an AR, and software program/s co-operating and/or realizing the method according to the invention. The invention provides a smoother handover.
