  • Patent number: 8055264
    Abstract: Disclosed is a method for controlling handoff by a network infrastructure, which includes collecting channel information and transmitting the channel information to a Mobile Terminal (MT) and a method for controlling handoff by a MT, which includes receiving channel information collected by a network infrastructure and making a handoff decision according to the channel information. The present invention also discloses apparatuses for controlling handoff. Applying the present invention, the handoff decision will be made based on both the information collected by the network infrastructure and the information collected by the MT, therefore blind handoff is reduced, the network workloads are balanced and the QoS is assured before and after the handoff.
