HandOver

After quick handover, bad quality handover, and TA handover are successful, penalty is applied onthe old cell during the penalty time to prevent an immediate handover back to the old cell.

During TA handover, if the TA Threshold of a co-site neighboring cell is lower than or equal tothe TA Threshold of the serving cell, a handover to the cell is prohibited.

Intra-cell handover is allowed for the interference handover. However, when intra-cell handover istriggered several times continuously, it will be forbidden within a specified duration.

On the enhanced dual-band network, the MS should not be handed over to a cell in the sameunderlaid/overlaid cell group when the load handovers between the overlaid cell and the underlaidcell (specified by Load HO From UL Subcell to OL Subcell Allowed and Load HO of OL Subcellto UL Subcell Enabled) are allowed. This is to prevent a load handover of a normal cell fromcolliding with a load handover between the overlaid cell and the underlaid cell on the network.

PBGT handover toward a cell of the same group is not allowed once it is triggered between theenhanced dual-band network cells.

After the fast-moving micro cell handover is successful, penalty is applied on all the neighboringmicro cells.

SDCCH handover supports the quick handover, TA handover, bad quality handover, quick leveldrop handover, interference handover, no downlink measurement report handover, edge handover,and fast-moving micro cell handover. It does not support the enhanced dual-band networkhandover, load handover, hierarchical handover, PBGT handover, AMR handover, better 3G cellhandover, concentric cell handover, and tight BCCH handover.

2. Start the BSSAP message tracing task by referring toTracing Messages on the A Interface.Expected result: The BSC sends the MSC a Handover Performed message with thehandover cause value ofbetter-cell,distance, uplink-quality, downlink-quality, traffic, uplink-strength, ordownlink-strength.

In the case of the quick handover, the handover cause value is better-cell.

In the case of the TA handover, the handover cause value is distance.

In the case of the BQ handover, the handover cause value is uplink-quality ordownlink-quality.

In the case of the rapid level drop handover algorithm, the handover cause valueis uplink-strength.

In the case of the interference handover, the handover cause value is uplink-quality ordownlink-quality.

In the case of the no downlink measurement report handover, the handover cause valueis uplink-quality.

In the case of the enhanced dual-band network handover, the handover cause value

is better-cell ortraffic.

In the case of the load handover, the handover cause value is traffic.

In the case of the edge handover, the handover cause value is uplink-strength ordownlink-strength.

In the case of the fast-moving micro cell handover, the handover cause value is better-cell.

In the case of the inter-layer handover, the handover cause value is better-cell.

In the case of the PBGT handover, the handover cause value is better-cell.

In the case of the AMR handover, the handover cause value is downlink-quality.

In the case of the SDCCH handover, the handover cause value is better-cell, distance, uplink-quality,downlink-quality, traffic, uplink-strength, ordownlink-strength.
