摘要： A CDMA network dynamically generates hard handoff (HHO) target sets to support mobile station HHO. Dynamically identifying CDMA channels or cells as targets for HHO eliminates the need for statically configured HHO target sets. In an exemplary embodiment, a source BSS identifies a first set of channels corresponding to common neighbor cells of the cells associated with the active set pilots and/or reported PBU pilots. This first set may be adjusted by removing any common neighbor cells that include soft handoff target channels, and by adding selected vertical neighbor channels of the active set pilots and/or reported PBU pilots. Channels in the first set may be grouped by carrier frequency and evaluated based on CDMA channel type, BSS affiliation and characteristics, and the target's relationship to the active set to identify a preferred HHO target set. Such operations permit dynamic determination of whether to perform inter- or intra-BSS HHO.
