AdjgRxLevMinHO(n) determines the minimum Required RSSI (dBm) level of the neighbor cell(n). AdjgTxPwrMaxTCH(n) indicated the maxi

13、mum Tx power level (dBm) an UE may use in GSM neighbor cell(n). P_MAX is the maximum UE power capability. If several GSM cells fulfil the equation above, cells are ranked based on HOPG: AdjgPriorityCoverage/0, range 07 A cell is ranked higher than another cell if it has a higher priority level even

14、though its signal strength condition was worse Inter-system HO could be forbidden during the first measurements reports from the UE, to let the UE report all the candidate inter-system cells in its neighbor hood.
