Title: Method for inter-frequency hard handover
Inventor: LEE KYOUNG LAK
IPC: H04B7/26
Filed: 2007-10-16
Abstract: An inter-frequency hard handover method for preventing deterioration of the voice quality by the coverage inconsistency is provided to apply the negative number to the hysteresis value and to perform handover even though network signal of a target cell is less than network signal of a source cell. A measurement result including hysteresis value is received(S201). The mobile communications terminal measures the network signal of the target cell and source cell(S203). The mobile communications terminal compares the sum total of the standard value with the net signal value of the measured source cell(S205). If the hard handover requisite is satisfied, the mobile communications terminal transmits the measured result information to the mobile communications systems(S207). According to the mobile communications terminal is the indication of the mobile communications systems, the hard handover procedure is performed(S209). A handover complete message is transmitted to the mobile communications systems(S211).
