ABSTRACT:
The present invention a system and method are provided for performing an inter-frequency search with reduced loss of link frames in a CDMA system. The CDMA system includes a base station (20) and a mobile station (50). The mobile station (50) has a searcher (164), which searches for pilot channels. The signal strengths of these pilot channels are then reported to the base station (20). This searching results in erased portions of a data frame (238). After the signal strengths are reported to the base station (20), the mobile station (50) informs the base station (20) of the parameters related to the search. These parameters may include the frame of the search, the start position of the search, and the length of the search. The mobile station (50) and the base station (20) then replaces the erased portions of the frame with corrective data such as soft zeros.
