In this step.. including network identity parameters. Step 6 Expected result: si2-quarter-ind in System Information Type 3 message is 0. Based on the received system message. set Index Type to BYID. Set INTERRATCELLRESELEN of the original cells to YES. Then. an MS can properly select and access a radio network.GSM Feature Configuration 20 Configuring Abis over IP 1 Context Configuring System Information Sending Prerequisites   The original cells have 2G neighboring cells. They can be used to solve the problems of continuous coverage and sporadic coverage in hotspot areas. Hybrid cells can increase the cell capacity. signals of the DCS1800 band are about 15 dB weaker than those of the GSM900 band.GSM Feature Configuration 20 Configuring Abis over IP 2 Prerequisites Context Configuring Hybrid Cell The BTS must support the configured frequency bands. Therefore. a channel in the overlaid subcell is not directly assigned to a call. A hybrid cell consists of an underlaid subcell and an overlaid subcell. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. The traffic in the underlaid subcell and the overlaid subcell should be properly assigned to maintain the load balance between the overlaid subcell and the underlaid subcell.. If the overlay cell is configured in the PCS1900 band. the underlaid cell is configured in the GSM900 or GSM850 band. the BCCH is generally configured on the GSM900 TRX. decrease the number of handovers. whereas the DCS1800 or PCS1900 TRX is configured in the overlaid cell to absorb the traffic. the GSM900 or GSM850 TRX is configured in the underlaid cell to expand the coverage. Avoid using a multi-layer concentric cell due to inconsistent combination modes of the TRXs on the same frequency band. The FH within the same frequency band is allowed. The frequency hopping (FH) between GSM900 and DCS1800 is not allowed. At the distance of 0. Ltd 1     Issue 01 (2010-11-04) . Generally. A multi-layer concentric cell affects the network KPIs. such as the handover success rate and assignment success rate. The frequency band configuration is as follows:  If the overlaid subcell is configured in the DCS1800 band. an incoming inter-cell handover request is not directly assigned to the overlaid subcell. and a call beyond the coverage of the DCS1800 TRX is not forcibly assigned to the overlaid subcell. the underlaid cell is configured in the GSM850 band.5 km to 1 km. The signal loss of the DCS1800 band changes with the transmission distance. and reduce system interference.  The configuration of the hybrid cell should comply with the following principles:  Generally. The priorities of different types of TRXs are: P-GSM > E-GSM > R-GSM. ----End 2 Huawei Proprietary and Confidential Copyright © Huawei Technologies Co. In this step..

UL Subcell Lower Load Threshold to 50. MS1 is assigned to a channel in the overlaid subcell. Step 9 Run the MML command SET GCELLHOCTRL to set the parameters of the DCS1800 cell. MS2 is assigned to a channel of the DCS1800 cell because the load of the underlaid subcell is higher than the value of UL Subcell General Overload Threshold. MS1 is handed over to the GSM900 cell because the load of the underlaid subcell is lower than the value of UL Subcell General Overload Threshold. Step 14 Maintain the call of MS1. In this step. Then. and UL Subcell General Overload Threshold to 80. MS1 is assigned to the underlaid GSM900 subcell because the load of the underlaid subcell is not higher than the value of UL Subcell Lower Load Threshold.

You can change the level of the underlaid subcell to be higher than the level of the overlaid subcell. and Inner Cell EDGE HO Enable to YES. Step 15 The call is handed over from the GSM900 cell back to the DCS1800 cell because the load in the underlaid subcell is higher than the value of UL Subcell General Overload Threshold. In this step.. Step 17 MS1 is handed over the GSM900 cell because the receive level of MS1 is lower than the level of Outgoing OL Subcell HO Level TH. The HANDOVER PERFORM message can be traced on the A interface and the handover cause value in the message is better cell. This type of edge handover requires that the underlaid subcell is more preferably selected as the target cell for handover than the overlaid subcell. Incoming OL Subcell HO Level TH to 63.
