1. A method for cell planning and preparing for a cell split when a cell tends to get congested or overloaded in a cellular mobile telecommunication system, wherein the steps of said method are performed in one or more nodes of said telecommunication system, said method comprising the steps of:

  • registering position related data comprising the locations for mobile users (MS) together with what service is used by each user in terms of bit rate;

    creating an estimation of the traffic density within the cell as a function of said position related data; and

    ,selecting an optimal site for a new base station as a function of said position related data; and

    ,selecting an optimal site for a new base station as function of said position related data or said traffic density;

    wherein maximizing the function
    xopt,yopt=max f(BRn/PLn,xn,yn) for all ngives the optimal site location for the new base station, where n is an index number for the mobile users of the cell, BRn is the bit rate used, PLn is the path loss and Xn, yn is the location of the user n.
