This measurement function allows Internal Handover information per observed CELL to be collected on a per adjacent originating or target CELL basis. This is achieved by specifying the adjacent originating or target CELL identity as parameter when initiating the Measurement Function.

B.2.2.1 Attempted incoming Internal inter CELL Handovers per originating CELL

A. This measurement provides the number of attempted incoming Handovers into the observed CELL from the specified adjacent originating CELL, controlled by this BSC, further information can be found in 3GPP TS 04.08 [2], 3GPP TS 08.08 [5] and 3GPP TS 08.58 [6].

B. CC.

C. An occurrence of a BSC internal event, depending on Handover algorithm.

D. attIncomingInternalInterCellHDOsPerOriginatingCell.

E. A single integer value for the observed CELL from the originating CELL.

F. Internal HDO Measurement Function.

G. Valid for circuit switching.

B.2.2.2 Successful incoming Internal inter CELL Handovers per originating CELL

A. This measurement provides the number of successful incoming Handovers into the observed CELL from the specified adjacent originating CELL controlled by this BSC.

B. CC.

C. Transmission of a "HANDOVER PERFORMED" Message to the MSC (3GPP TS 08.08 [5]).

D. succIncomingInternalInterCellHDOsPerOriginatingCell.

E. A single integer value for the observed CELL from the originating CELL.

F. Internal HDO Measurement Function.

G. Valid for circuit switching.

B.2.2.3 Attempted outgoing Internal inter CELL Handovers per target CELL

A. This measurement provides the number of attempted outgoing Handovers from the observed CELL to the specified adjacent target CELL controlled by this BSC.

B. CC.

C. Transmission of a "HANDOVER COMMAND" Message (3GPP TS 04.08 [2]).

D. attOutgoingInternalInterCellHDOsPerTargetCell.

E. A single integer value for the observed CELL to the target CELL.

F. Internal HDO Measurement Function.

G. Valid for circuit switching.

B.2.2.4 Successful outgoing Internal inter CELL Handovers per target CELL

A. This measurement provides the number of successful outgoing Handovers from the observed CELL to the specified adjacent target CELL controlled by this BSC.

B. CC.

C. Transmission of a "HANDOVER PERFORMED" Message to the MSC (3GPP TS 08.08 [5]).

D. succOutgoingInternalInterCellHDOsPerTargetCell.

E. A single integer value for the observed CELL to the target CELL.

F. Internal HDO Measurement Function.
