IPC: H04B7/26
Filed: 2005-05-16
Abstract: A handover method in the portable Internet is provided to enable a mobile terminal to reserve resources for a communication path in case of handover of a network layer in the portable Internet, thus the delay required in a resource reservation protocol can be reduced while handover delay is decreased. A mobile terminal transmits information about a target BS(Base Station) to a serving BS when handover occurs, in order to deliver the information to an RNC(Radio Network Controller). The RNC previously reserves resources to the target BS by using the information about the target BS. The RNC multicasts traffic to the serving BS and the target BS. The serving BS and the target BS store packets. If the handover to the target BS is successful, the terminal receives the multicasted traffic from the target BS. The RNC processes the handover of a network layer.
