A packet communication system having a wireless terminal, a plurality of wireless access networks, and a packet communication device connected to the respective wireless access networks, that includes a unit controlling handover processing for handover of the wireless terminal to a different wireless access network. Also included is a unit checking whether a handover destination wireless access network supports a header compression or decompression method used in a first packet communication performed through a handover source wireless access network, at a time of the handover. Also included is a unit controlling an execution point for processing corresponding to the header compression or decompression method to be specified at the packet communication device for a second packet communication performed through the handover destination wireless access network, when the above network does not support the method. |
