Abstract

A gateway module, a communication method, and a computer program product thereof are provided. The gateway module is adapted for use in a network framework comprising a mobile station, a plurality of interworking units, a first wireless network, and a second wireless network. The mobile station is located within the signal coverage of the first wireless network and the second wireless network, and accepts network service provided by the first wireless network. The gateway module receives a handover request signal of the first wireless network, selects a handover interworking unit from the interworking units according to the handover request signal, and transmits the handover request signal to the second wireless network. Thereby, the mobile station can handover to the second wireless network to accept the network service provided by the second wireless network.
