HANDOVER FOR PACKET SWITCHED DATA

摘要

There is disclosed a method of handing over communication of packet switched data from a mobile terminal moving between a first routing area defined in a cellular communications network and a second routing area, wherein a temporary logical link identifier has been assigned to said communication in the first routing area, the method comprising the steps of: identifying that the mobile terminal has moved from the first routing area to the second routing area; supplying a temporary handover identity; transmitting packets in a downlink direction to the mobile terminal during a handover period, each packet including the temporary handover identity; during said handover period assigning a new temporary logical link identifier to the mobile terminal and ceasing to include the temporary handover identity in subsequent packets when the new temporary logical link identifier has been assigned.
