CALL CONTINUITY USING SHORT-RANGE COMMUNICATIONS HANDOFF

摘要

A call is made from a user equipment (UE) device to a first other UE device that is is paired to a short range communications device. The first other UE device monitors the respective connections between short range communications device and the first other UE device and a second other UE device and automatically hands over the telephone call from the first other UE device to the second other UE device when the connection between the short range communications device and the second other UE device is stronger than the connection between the short-range communications device and the other first UE device. The cordless headset 172 is concurrently handed off from the first other UE device to the second other UE device.

主权项

1. A device comprising:
a call interface that receives call data from and provides call data to a first other device; a network interface through which a communication channel is established with a second other device; a short-range communication interface through which data is communicated between the device and a short-range communication device; and a processor coupled to a non-transient compute readable medium, the computer readable medium including programming instructions which cause the processor to:
process the call data received through the call interface to establish a first communication channel between the device and the first other device;control the network interface to establish a second communication channel between the device and the second other device and to provide the call data to the second other device via the second communication channel;determine at least one of relative strength, latency or quality of service (QoS) of respective connections between the short range communication device and the device and between the short range communication device and the second other device; andwhen the short range communication device is determined to have a better connection with the second other device than the short range communication device has with the device, transfer the call data to the second other device and concurrently hand off the short range communication device to the second other device.
