ABSTRACT:
A method for dynamically handling the data path of a wireless IP phone is provided. The method comprises establishing a first communication link between the wireless IP phone and a wireless local area network (WLAN), establishing a second communication link between the wireless IP phone and a general packet radio service (GPRS) network, establishing a conversation session between the wireless IP phone and a second IP phone via a voice over internet protocol (VoIP) through the first or second communication link, determining whether the data path of the conversation session passes through the first or the second communication link according to a signal strength of the first communication link, and exchanging a plurality of packets of the conversation session through the data path.
