1. A method for locating a mobile station in a distributed manner using radio signals between the mobile station and mobile network, comprising steps:

  • obtaining differences of propagation times of signals propagating between the mobile station and other stations of the mobile network;

    performing a locating process by location computing based on said differences of signal propagation time;

    wherein said location computing includes steps of;

    distributing the computing between a mobile network element and the mobile station by dividing the location computing into operation sequences by forming a first set of operation sequences and a second set of operation sequences separated by an execution boundary therebetween, said execution boundary being dynamically set between any location computing operations; and

    carrying out said first set of operation sequences in a mobile station and carrying out said second set of operation sequences in the mobile network element.
