How OsmBSC was extended to support inter-BSC hand-over next to the existing intra-BSC hand-over support.
In 2018, OsmoBSC has undergone significant changes to allow inter-BSC (also called "external") hand-over on the A interface. The previous hand-over implementation only supported intra-BSC type hand-overs, where both the source and the target cell are served by the same BSC.
In order to support hand-overs at the edge of BSC coverage areas, inter-BSC hand-over was implemented.
This talk describes the history, implementation and its configuration/use of this new OsmoBSC feature.
