ABSTRACT:
A method and system for handing over on-going communications to a target cell including a plurality of low power channels, for handling ongoing calls, and a plurality of higher power channels for handoff. The ongoing call is switched from a low to a higher power channel upon receiving a handoff request. The on-going call is using the higher power channel until a determination is made that the handoff is necessary or unnecessary. The quality of reception of the serving cell and target cell is compared to determine the necessity.
