Abstract
An adaptive handoff algorithm that governs mobile handoffs between sectors within base stations in a CDMA system is disclosed. The handoff algorithm is selected according to the type of service requested by the mobile. Further, the handoff algorithm uses various quality measures in order to induce mobile handoffs that result in desirable operating conditions for the type of service requested by the mobile. For example, a voice call may result in an handoff algorithm that induces the mobile to handoff to sectors that minimizes the mobile output power in order to maximize battery capacity and decrease uplink interference. Moreover, another algorithm may be implemented for packet intensive services, such as internet web browsing, to induce the mobile to handoff to sectors that result in reduced downlink output power, which tends to decrease interference in the cell.
