Incoming-to-BSC HO Optimum Layer |
|---|---|
Description |
In a concentric cell, the channel assignment for an incoming-BSC handover can be processed in one of the following modes: Overlaid Subcell: A channel in the OL subcell is preferentially assigned. Underlaid Subcell: A channel in the UL subcell is preferentially assigned. No Preference: A channel is assigned according to general channel assignment algorithms. |

Configuration Policy |
For the network with a single frequency band, inter-BSC handovers are triggered at the edge of two adjacent cells. Therefore, the recommended value of this parameter is Underlaid Subcell. For a dual-band network (for example, 900/1800 MHz cells), incoming BSC handovers occur frequently and are generally not triggered at the edges of adjacent cells. In this case, the recommended value of this parameter is Overlaid Subcell. In the case that success rate of handovers drops, UL Subcell is preferred for incoming BSC handovers. |
