  • the process causes the MS unit to effect call setups in accordance with a programmed sequence, through one or more of the BS units which the MS unit has registered in its "neighbour" list of neighbouring base stations.
  • the call setups result in the MS unit registering TA and CelllD.
  • the parameters TA and CelllD are obtained from the signals Immediate Assignment and System Information Type 6 respectively, which are specified in GSM.
  • the signals are transmitted to the MS unit on layer 3 level (Layer 3 Level according to the OSI model).
  • the MS unit ends the positioning queries according to the neighbouring list by sending a response in return to the position handler 14 with a modified SMS.
  • the SMS contains all measuring results obtained with measured BS units.
  • the embodiment including short message services also includes the possibility of ordering an MS unit to trigger its position.
  • the position handler has then been ordered to send a modified SMS message which contains one or more CelllDs.
  • the MS unit finds this CelllD in the signal system, information type 3 in GSM, which is received by the MS unit in idle mode, during the measuring process, the MS unit is triggered to position itself in accordance with the aforegoing and to send the response in return to the position handler 14, via a modified SMS.
  • This enables the positioning of an MS unit to be programmed beforehand in a known manner and automatically released.
  • an MS unit was localized with an area of ⁇ 200 m.
  • the MS unit was located in Strandvagen in the vicinity of Nybroplan and the position handler 14 quite rightly localized the MS unit as being in Strandvagen, about 200 m southwest of the exact place in Strandvagen.
  • the alternative embodiment of the present invention utilizes centre-of-gravity calculations based on the parameter TA in multi-station measuring processes, described in more detail with reference to Fig. 4.
  • Fig. 4 is a schematic or simplified chart showing land contours 48 and sea 50.
  • the chart includes three circles, either complete or partial, showing TA limits 46 in relation to BS units 44 (sites).
  • the BS units 44 are placed in the centre of a cell 42. In Fig. 4, the area covered by one cell is so large that its BS unit 44 is located outside the chart.
  • the exact position of the vehicle 40 or MS unit on the chart is marked with a triangle.
  • the inner circles 46 constitute TA limits, with 0-63 TA limits according to the Europolitan system Operator among others, there being obtained a distance of about 550 m between TA limits.
  • the distance of an MS unit to a BS unit can be determined with a resolution of about 550 m in a cell.
  • Three TA limits 46 intersect one another in Fig. 4. If the parameter TA for each limit in Fig. 4 is used to calculate a common centre of gravity in accor- dance with known mathematical formulae for such calculations, the centre of gravity will lie in the section of the TA limits marked by the surface 52. The surface 52 thus consti ⁇ tutes the uncertainty or the resolution in the calculation.
  • the MS unit sequence with Paging Request is repeated for more than three BS units registered in the MS unit, therewith obtaining a smaller section.
  • the position of an MS unit is estimated with a centre-of- gravity calculation method. The calculation is based on the measuring data sent by the MS unit to the position handler 14.
  • the position handler 14 includes memory resident informa- tion relating to the positioning of BS units and their respective coverage areas. This data is used as a basis for calculating the positions of MS units.
  • the centre of gravity constitutes the surface that is delimited by the measuring data obtained from MS units and intended for positioning said units.
  • VLR area the service area in which the vehicle carrying the mobile station is located, i.e. which Operator and in which country.
  • the time of registration of the mobile telephone network of a foreign Operator is distributed by the GSM network to the HLR register of Operators in which MS units belonging to the service sub ⁇ scriber are registered.
  • all other already described functions and/or services can be used over national borders, for instance via an X.25 (interface functions when connecting data equipment to packet coupled networks) connection.
