Patent ID: 7146167

Claim:
A non-instantaneous-disruption hard handover (HHO) control device disposed in a radio base station using a CDMA technique, for handover of a call from a source baseband resource to a destination baseband resource, said HHO control device comprising a call-processing/maintenance processing monitoring block for receiving radio link information including information of said source baseband resource and information of said destination baseband resource, from a host radio network controller (RNC) managing baseband resource information, for management of said radio link information by said call-processing/maintenance processing monitoring block, characterized in that: a CFN message generation block ( 110 ) for generating a connection frame number (CFN) which specifies a handover timing is provided in said call-processing/maintenance processing monitoring block ( 109 ); and each of baseband signal blocks provided in a baseband signal unit includes: a search block for generating acquired path information of a corresponding said baseband resource; a codec block for generating radio-frame-synchronization identification information and transmission-power control information of a corresponding baseband resource; and an HHO-information write-in/read-in block for collecting non-instantaneous-disruption HHO information including radio-frame-synchronization identification information, transmission-power control information, and acquired path information of a corresponding baseband resource.
