Method and system for signalling the transfer of voice calls between access points in a wireless local area network
First Claim
1. A method for signalling 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.

10. A system for signalling 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 the system, the system comprising:
-
a processor coupled to the wireless network; and
,a program executed by the processor, the program including;
a module for receiving 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
,a module for sending 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer program product having computer executable code for directing a system to signal 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 the system, the code comprising:
-
code for receiving at the system 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
,code for 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. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
