摘要： IP unicast communication is provided between mobile devices in a wide area network and a wireless local area network coupled by a gateway component. Data communication is established between a mobile device and the wireless local area network, thereby receiving a first unicast IP address associated with the mobile device. A multicast group is joined within the wireless local area network and registering with that multicast group using a predetermined multicast IP address as a destination IP address and the first unicast IP address as a source address. The device disconnects from data communication within the wireless local area network, thereby releasing the first unicast IP address. Data communication is established between the mobile device and the wide area network, thereby receiving a second unicast IP address associated with the mobile device. The device then automatically communicates with the gateway component, via the wide area network, to specify the second unicast IP address as the source address for the mobile device within the multicast group.
