Northforce, actually ANSI-41 MAP and GSM-MAP probably co-exist in the core networks serving AWS, Cingular, and T-Mobile, with ANSI-41 MAP for the older TDMA phones. Gee, those guys had to *overlay the core network and the RAN network. And they jumped from an Amercian version of TDMA to the European version of TDMA. Some technology jump. All for the privilege of doing a second RAN overlay later to jump to W-CDMA. (When one jumps from one horse to another often enough, sooner or later one misses the horse.) This path *versus one CDMA2000 1x overlay, with no GSM MAP overlay, and no 2nd RAN overlay later to get to 3G. And then they also chose to use E-OTD(OA), or TDOA, or U-TDOA for their cellphone location technology. If they couldn't figure it out from a technological perspective, a psychic executive could at least have taken a clue from the DOA* portion of those acronyms. The phrase "numb from the neck up" comes to mind. Ron

>>>> terms softer, soft, and hard handoff Ron, Thanx for the handoff refresher. I now better understand you comments regarding "inner core" and the importance of choose my words more carefully. I take it that the type of handoff I'm contemplating is more of a peer-to-peer nature. Has anyone yet to coin the term peer handoff? I've sent Eric a copy of this url. Hopefully, he'll get involved in this discussion. In a peculiar way, developments in this area could benefit both sides of the battle. It's kind of like a demilitarized zone and, if not built by the combatants, it's possible that the parties could get "napstered". Your comments were educational are appreciated. Trevor {eom}
