<p>The invention provides a method in a user terminal for assisting handover of a session from a first radio access point to a second radio access point, comprising:
a) establishing that said session is to be handed over from AP1 to AP2,
b) fetching a first packet from a first buffer memory (245),
c) extracting a frame sequence number, FSN, from said first packet and storing FSN in a first memory space of a second buffer memory (243),
d) forwarding said first packet to an application running on said UT (240) or to a higher level protocol of said UT (240),
e) fetching a next packet from said first buffer memory (245),
f) extracting a frame sequence number from said next packet,
g) establishing whether said next packet is a consecutive packet of said first packet,
h) storing said frame sequence number in said first memory space of said second buffer memory (243) and forwarding said "next packet" to a higher level protocol or a final application if it was established in step g) that said "next packet" is a consecutive packet of said first packet, and otherwise buffering said "next packet" in a second memory space of said second buffer memory (243).</p> |
