Abstract
A method and system for performing a handoff of a cellular telephone call from a calling station to a mobile cellular telephone between an old intelligent cell site and a new intelligent cell site. The handoff is accomplished by using a conference bridge in a switch to connect a call segment to the new intelligent cell site to the call segments from the calling station to the old intelligent cell site. When a talk path to the new intelligent cell site is established, the talk path to the old intelligent cell site is terminated. The handoff is therefore accomplished by utilizing a conference bridge in the switch rather than putting an existing call on hold while a connection to a new intelligent cell site is established. Using a conference bridge to accomplish a handoff results in minimal interruption in the talk path of the call such that the handoff is imperceptible to the user.
