Abstract
A method for signaling a transfer of a voice call communicated between a wireless device and a second device from a first access point to a second access point in a wireless network, the second device coupled to the first and second access points through a server, the method comprising: receiving at the server from the wireless device a message indicative of a pending transfer between the first and second access points, wherein the wireless device determines whether to send the message by monitoring a characteristic of signals received from each of the first and second access points; and, sending from the server to the second device a message indicative of the pending transfer to thereby prepare the second device for a possible interruption of the voice call.
