  • Patch Set #2, Line 12: In small base stations, the PCU is usually co-located inside the BTS. In this

    Hmm. I am also not sure about this. I wonder how it is with large IP based BTS. […]

    Size has nothing to do with it. It's an architectural decision. The latency of GPRS on the radio interface is so high that you don't really care about the (usually super short) latency of a terrestrial CCU-PCU backhaul.

    The main reason for old/established vendors' PCU being BSC-colocated is, I guess, for backwards copatibility (we've always done it that way, our codebase is built around the assumption) and also the fact that in network-assisted or network-controlled cell changges or actual hand-over in GPRS it is much easier to do from an element that has all the state of the neighbor cells, vs. just the state of one cell.

    Please remove the notion of "small" here. You can write "In most OsmoPCU-supported base stations" or something like that, which is certainly true.
