摘要： The present invention provides a method for supporting handoffs of a first mobile unit in a wireless communication system that supports multiple vocoder technologies. The method includes allocating, prior to completion of a handoff of the first mobile unit, a transcoder function to the first mobile unit. The method also includes detecting a change in a format of at least one packet received from the first mobile unit. The change indicates that the vocoder technology used by the first mobile unit to form packets has changed. The method also includes transcoding packets in response to detecting the change in the format.
