Description

If a handover is required according to the handover algorithm and the source cell (current cell) is also the target cell, the BSC assigns a proper channel in the target cell (the target cell is also the source cell) and then sends a CHAN ACTIV message to the BTS of the target cell (the target cell is also the source cell) to activate the channel of the target cell determined by the handover algorithm. Upon receipt of a CHAN ACTIV ACK message, the BSC requests the relevant resource and sends an HO CMD message to the MS through the source cell after the resource is successfully obtained, instructing the MS to initiate a handover from the source cell to the target cell.

The counters provide the numbers of HO CMD commands sent by the BSC through the source cell (current cell) to the MS based on the type of the channel the MS seizes before the handover and the handover reason. These counters can be combined with the Internal Intra-Cell Handover Requests and the Failed Internal Intra-Cell Handovers to reflect the performance of internal intra-cell handovers.

The counter H3010 indicates the number of internal intra-cell handover commands sent by the BSC when the MS seizes an SDCCH before the internal intra-cell handover. The counter H3017 indicates the number of internal intra-cell handover commands sent by the BSC when the MS seizes a TCHF before the internal intra-cell handover. The counter H3018 indicates the number of internal intra-cell handover commands sent by the BSC when the MS seizes a TCHH before the internal intra-cell handover. Each time an internal intra-cell handover command is initiated, the counter H3010, H3017, or H3018 is incremented by one based on the type of the channel the MS seizes before the handover.

H3017: CELL_INTRACELL_HO_CMD_TCHF
H3018: CELL_INTRACELL_HO_CMD_TCHH

The counter H3013A indicates the number of internal intra-cell handover commands sent by the BSC to the MS for a TCHF-TCHH conversion. The counter H3013B indicates the number of internal intra-cell handover commands sent by the BSC to the MS for a TCHH-TCHF conversion. Each time the BSC sends an internal intra-cell handover command to the MS for a TCHF-TCHH or TCHH-TCHF conversion, the counter H3013A or H3013B is incremented by one based on the type of the conversion.

H3013B: CELL_INTRACELL_HO_CMD_TCHH_TCHF

The counter H3014A indicates the number of internal intra-cell handover commands sent by the BSC to the MS for a TCH-SDCCH conversion. The counter H3014B indicates the number of internal intra-cell handover commands sent by the BSC to the MS for an SDCCH-TCH conversion. Each time the BSC sends an internal intra-cell handover command to the MS for a TCH-SDCCH or SDCCH-TCH conversion, the counter H3014A or H3014B is incremented by one based on the type of the conversion.

H3014A: CELL_INTRACELL_HO_CMD_TCH_SD
H3014B: CELL_INTRACELL_HO_CMD_SD_TCH

The counter H3012 indicates the number of internal intra-cell handover commands sent by the BSC to the MS when the MS hands over from the underlay of a concentric cell to the overlay of the cell. The counter H3011 indicates the number of internal intra-cell handover commands sent by the BSC to the MS when the MS hands over from the overlay of a concentric cell to the underlay of the cell. Each time the BSC sends an internal intra-cell handover command to the MS for a handover from the underlay to the overlay or from the overlay to the underlay, the counter H3012 or H3011 is incremented by one based on the type of the handover.

H3012: CELL_INTRACELL_HO_CMD_ULCELL_OLCELL
H3011: CELL_INTRACELL_HO_CMD_OLCELL_ULCELL

The counter H301a indicates the number of internal intra-cell handover commands sent by the BSC to the MS for the calls that use the local switching function of the BSC. The counter H301b indicates the number of internal intra-cell handover commands sent by the BSC to the MS for the calls that use the local switching function of the BTS. Each time the BSC sends an internal intra-cell handover command to the MS for a call that uses the local switching function of the BSC or the BTS, the counter H301a or H301b is incremented by one.

H301a: CELL_INTRACELL_HO_CMD_BSC_LOOP
H301b: CELL_INTRACELL_HO_CMD_BTS_LOOP

The counter H3015A indicates the number of internal intra-cell handover commands sent by the BSC to the MS for a TCHF-TCHH conversion for an AMR call. The counter H3015B indicates the number of internal intra-cell handover commands sent by the BSC to the MS for a TCHH-TCHF conversion for an AMR call. Each time the BSC sends an internal intra-cell handover command to the MS for a TCHF-TCHH or TCHH-TCHF conversion for an AMR call, the counter H3015A or H3015B is incremented by one based on the type of the conversion.

H3015A: CELL_INTRACELL_HO_CMD_AMR_TCHF_TCHH
H3015B: CELL_INTRACELL_HO_CMD_AMR_TCHH_TCHF

Unit

Integer number or integer.

Measurement Point

Each time the BSC sends an HO CMD message through the source cell to the MS, one of the counters given above is incremented by one based on the type of the channel the MS seizes before the handover and the handover reason.
