1. A method of optimizing a managed handover technique within a radio cellular environment, said method comprising:

  • a mobile station performing a training sequence and identifying base stations to use during travel along a path, the training sequence including;

    determining an identification of the mobile station traveling along the path, said mobile station having no previous history of base station connectivity;

    as said mobile station establishes a connection with a base station, associating, based upon said base station being used by said mobile station, said identification with a known route selected from a database having stored maps of more than one said known route including a list of base stations along each said known route;

    as said mobile station disconnecting from said base station and connecting to a subsequent base station, said mobile station storing historical information regarding said base station and said subsequent base station;

    said mobile station comparing said base station and said subsequent base station to said list of base stations along said known route in order to identify one or more of said known routes that include both said base station and said subsequent base station;

    said mobile station repeating said storing and comparing steps for further subsequent base stations, until only one of said known routes remains and corresponds to said path traveled by said mobile station;

    said mobile station determining whether a direction of travel of said mobile station along said path is forward or reverse along said known route that corresponds to said path;

    said mobile station identifying one of said stored maps from said database that correlates to both said direction of travel and said known route remaining that corresponds to said path traveled; and

    said mobile station assigning a preferred sequence of base stations corresponding to said one of said stored maps for all further connections with said mobile station along said path.
