Hard hand-off timing determining method through software
First Claim
1. 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.

Abstract
An inter-cell hard hand-off timing determining method performs inter-cell hard hand-off by clearly determining a hand-off timing with a software method without assistance of hardware, thereby smoothly enabling traffic in a small base station that is installed in a shadow region or low traffic regions and reducing undesirable addition for hardware in increasing the small base station. The method is performed by the following steps of: identifying whether a mobile station has moved to a small base station; when it is determined that the mobile station has moved to the small base station, asking a selector and vocoder processing execution to report a power measurement report message having pilot signal strengths of an active set; reporting the PMRM to a call control execution; and when the mobile station is positioned at a boundary of a general base station, performing a inter-cell hard hand-off.
