Description

hoPriorityLevel (PRI) - kita memberi level prioritas ke adjacent cell (level prioritas sbg kandidat HO) - range 0-7 (makin besar angkanya makin tinggi prioritas adjacent cell tsb) hoLoadFactor (OF) - parameter ini menentukan seberapa banyak PRI site target (ini) diturunkan jika site target mengalami overload - ceritanya: saat site target/ini (katakan cell Iwan1) sedang overload, maka PRI dari cell2 surounding menuju Iwan1 akan diturunkan sebesar OF. Dengan penurunan PRI dari cell2 surounding menuju Iwan1, targetnya adalah HO incoming cell Iwan1 akan berkurang - OF tidak boleh lebih besar dari PRI hoMarginPbgt (PMRG) - With this parameter you define a threshold in the power budget process. The handover margin prevents repeated handover between adjacent cells - range -24 s/d 63 (makin besar angkanya makin susah HO) hoMarginLev (LMRG) - menetapkan threshold HO berdasarkan level - range -24 s/d 24 (makin besar angkanya makin susah HO) hoMarginQual (QMRG) - menetapkan threshold HO berdasarkan quality - range -24 s/d 24 (makin besar angkanya makin susah HO) rxLevMinCell (SL) - menetapkan level sinyal minimal dari adjacent cell, supaya adjacent tersebut menjadi kandidat untuk HO - range 0 s/d 63 (makin besar angkanya makin susah HO  susah muncul jadi kandidat HO) hoLevelUmbrella (AUCL) - menetapkan level sinyal minimal dari adjacent cell, supaya adjacent tersebut menjadi kandidat untuk HO (khusus adjacent umbrella cell) - lebih jelas lihat gambar di bawah fastMovingThreshold (FMT) - With this parameter you define the limit which is compared with the identification counter (fast moving MS) in the adjacent cell. If the limit is exceeded, the call is handed over from the macrocell to the best microcell. adjCellLayer (ACL) - With this parameter you define the adjacent cell layer in relation to the active cell. A call can be handed over to the cells that are visible to the serving cell by adjacency definition. This means the cells of upper layer, serving layer and lower

layer. The adjacent cell layer definition can be used, for example, in umbrella and power budget handovers in defining the target cells according to their layer. Hanya digunakan untuk adjacent beda layer)

drThreshold (DRT) - With this parameter you define the threshold value of the signal strength in the adjacent cell for the Directed Retry procedure. If the signal strength level in the cell is lower than this threshold value, adjacent cell is not accepted as a candidate in directed retry. - Pernah coba tapi seperti ga ngaruh om msPwrOptLevel (POPT) - With this parameter you define the optimum uplink RF signal level after a handover on a channel in the adjacent cell. If optimisation is enabled, the parameter indicates also the desirable uplink signal level after the handover. The optimisation procedure works only for intra-BSC handovers. The BSC presumes that the uplink signal level and the downlink signal level are in balance within the coverage area of the adjacent cell. If the downlink signal is, for example, 5 dB stronger than the uplink signal, set the value for this parameter 5dB higher than the desirable uplink signal level. Om, mungkin gambar ini bisa memudahkan pemahaman
