Abstract
Abstract The invention relates to an arrangement in mobile telecommunication systems which operate with cells to provide for an improved hand-over function of a mobile unit which is located in a cell which belongs to a first base station to a cell which belongs to a second base station. The mobile unit is provided with elements for measuring and evaluating parameters which are significant to the hand-over function on the one hand in the real traffic case and on the other hand in a simulated traffic case. A comparing element is arranged in the mobile unit and the said first and second representation are included as selection criteria for obtaining the improved hand-over function.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
176 words
Arrangement to provide a mobile unit in a telecommunication system having base stations with an improved hand-over function between cells of first and second base stations, characterized in that the mobile unit is provided with measuring elements which measure first parameters attributable to a real traffic case which are significant for the hand-over function in the real traffic case, in that the mobile unit is provided with evaluating elements which, with the aid of the measured first parameters, produce a first representation of how the mobile unit carries out the hand-over function in the real traffic case, in that the said evaluating elements are arranged to generate simulated second parameters attributable to a simulated traffic case and generate in dependence on the simulated second parameters a second representation of how the mobile unit carries out the hand-over function in the simulated traffic case, and in that an element containing the representations in the mobile unit is arranged to supply the said first and second representations for their utilisation as selection criteria in the improved hand-over function.
Claim 2
Dependent Claim
176 words

Claim 3
Dependent Claim
22 words
Arrangement according to claim 1, characterized in that the measuring element measures the field strength or the field strength and the quality.
Claim 4
Dependent Claim
29 words
Arrangement according to claim 1 or 2, characterized in that the evaluating element simulates desired output powers in both uplink and downlink without changing the actual level sent out.
Claim 5
Dependent Claim
23 words
Arrangement according to any of the preceding claims, characterized in that the evaluating element simulates desired frequency plans without changing the actual frequencies.
Claim 6
Dependent Claim
24 words
Arrangement according to any of the preceding claims, characterized in that the evaluating element simulates one or a number of second representations in parallel.
Claim 7
Dependent Claim
27 words
Arrangement according to any of the preceding claims, characterized in that the said first and second representation can be read out from the element containing the representations.
Claim 8
Dependent Claim
