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.

Abstract: System and method for providing network access to a mobile terminal includes a network gateway coupled to a first network and a second network, and a network controller coupled to at least one of the first network and the second network and configured to provide one or more functions for the first network. Additionally, the system includes a first access point coupled to the first network and configured to generate a first wireless network according to at least a first network protocol, and a second access point coupled to the first network and configured to generate a second wireless network according to at least a second network protocol. At least one of the first access point and the second access point is configured to communicate with a mobile terminal through the first wireless network or the second wireless network.
