Method and apparatus for performing handoff in a spread-spectrum communication system

摘要：

Handoff from a Code-Division, Multiple Access (CDMA) protocol to an Advanced Mobile Phone Service (AMPS) protocol occurs by comparing a remote unit's (405) phase shift measurement to a threshold (503) and determining a reference CDMA base station (401) from an active set of CDMA base stations (515). Next, corrected phase shifts are calculated for each CDMA base station in the active set (521) and the remote unit (405) is handed off to an AMPS base station (109) underlying the CDMA coverage area (126) having the smallest corrected phase shift (525).

摘要（中）：

通过将远程单元的（405）相移测量与阈值（503）进行比较并确定参考CDMA基站（401），将码分多址（CDMA）协议切换到高级移动电话服务（AMPS）协议）从一组有源的CDMA基站（515）获得。接下来，针对有源集合（521）中的每个CDMA基站计算校正的相移，并且将远程单元（405）切换到具有最小校正相位的CDMA覆盖区域（126）下方的AMPS基站（109）班（525）。
