Abstract:
An inter-cell hard hand-off timing determining method characterized by the steps of: identifying whether a mobile station moves from the cell region of a general base station to the cell region of a small base station through a call control execution (CCOX) in a base station controller; if YES in the identifying step, asking, at the CCOX, a selector and vocoder processing execution (SVPX) in the controller to report a power measurement report message (PMRM) that has pilot signal strengths of an active set to the CCOX; reporting, at the SVPX, the PMRM to the CCOX at predetermined times; identifying, by the CCOX that received the PMRM, whether the mobile station is positioned at the boundary of the general base station; if YES in the identifying step, performing an inter-cell hand-off by the controller.
