Abstract

In a cellular telephone system a system for directing communications between a mobile user (18) and cell-sites (12, 14, 16) as a mobile user (18) changes cell-site service areas. The mobile user (18) includes an~
apparatus (40, 46) for, while in communication with another system user via one cell-site, determining a transition of the mobile user (18) from the cell-site service area to the service area of another cell-site. The system includes circuitry (78) responsive to the indication for coupling communications between the mobile user and the other system user via the new cell-site while the mobile user also remains in communication with the system user via the first cell-site. The system further includes apparatus (78) responsive to the coupling of the communications between the mobile user and the other system user via the new cell-site for terminating the communications between the mobile user and another system user via cell-site with communications continuing between the mobile user and the system user via the new cell-site.
