Abstract
A method for performing a soft handoff, including establishing a first control channel via a network between a first BSC and a first BTS. The method also includes establishing a second control channel via the network between a second BSC and a second BTS. A call between a mobile station (MS) and the first BTS is established, and while the call continues an indication is sent to the first BSC that the MS has received a signal from the second BTS. In response to the indication, a trigger is conveyed from the first BSC to the second BTS, and, in response to receiving the trigger at the second BTS, further traffic associated with the call is directed between the MS, the second BTS, and the first BSC, without conveying the further traffic through the second BSC.
