Abstract:
1. A method for hand-off of a network communication session using background network scanning, the method comprising: in a device, establishing a communication path via a first wireless network for communicating, during a network communication session, an information stream via the first wireless network; detecting a second wireless network using background network scanning; determining service characteristics of the second wireless network from an access point of the second wireless network; determining a transmission delay of the second wireless network, in response to a predetermined criteria being met by the service characteristics of the second wireless network, wherein determining the transmission delay comprises: comparing transmission delay of the first wireless network and the transmission delay of the second wireless network; deciding to hand-off communication of the network communication session to the second wireless network based on the comparison, wherein the hand-off comprises switching communication of the information stream via the second wireless network; and after comparing and deciding, handing-off communication of the network communication session to the second wireless network.
