ETSI 3GPP TS 03.32 version 7.2.0 Release 1998 6 ETSI TS 101 109 V7.2.0 (2002-12) 1 Scope The present document defines an interm
21、ediate universal Geographical Area Description which subscriber applications or GSM services can use and the network can convert into an equivalent radio coverage map. For GSM services which involve the use of an “area“, it can be assumed that in the majority of cases the Service Requester will be f
22、orbidden access to data on the radio coverage map of a particular PLMN and that the Service Requester will not have direct access to network entities (e.g. BSC/BTS). The interpretation by the PLMN operator of the geographical area in terms of cells actually used, cells that are partly within the giv
23、en area and all other technical and quality of service aspects are out of the scope of the present document. This specification also provides a description of velocity that may be associated with a universal Geographical Area Description when both are applied to a common entity at a common time. 2 R

30、, (WGS 84), which is also used by the Global Positioning System, (GPS). The origin of the WGS 84 Co-ordinate system is the geometric centre of the WGS 84 ellipsoid. The ellipsoid is constructed by the rotation of an ellipse around the minor axis which is oriented in the North-South direction. The ro
31、tation axis is the polar axis of the ellipsoid, and the plane orthogonal to it and including the centre of symmetry is the equatorial plane. The relevant dimensions are as follows: Major Axis (a) = 6378137 m Minor Axis (b) = 6356752,3 14 m = 0,0066943800668 a2 - b2 b2 First eccentricity of the ellip
32、soid = Co-ordinates are then expressed in terms of longitude and latitude relevant to this ellipsoid. The range of longitude is -1 80“ to +1 SO“, and the range of latitude is -90“ to +90“. O“ longitude corresponds to the Greenwich Meridian, and positive angles are to the East, while negative angles
33、are to the West. O“ latitude corresponds to the equator, and positive angles are to the North, while negative angles are to the South. Altitudes are defined as the distance between the ellipsoid and the point, along a line orthogonal to the ellipsoid. 5 Shapes The intention is to incorporate a numbe
34、r of different shapes, that can be chosen according to need. - Ellipsoid Point; - - - Polygon; - Ellipsoid point with altitude; - - Ellipsoid Arc. Ellipsoid point with uncertainty circle; Ellipsoid point with uncertainty ellipse; Ellipsoid point with altitude and uncertainty ellipsoid; Each shape is
35、 discussed individually. 5.1 Ellipsoid Point The description of an ellipsoid point is that of a point on the surface of the ellipsoid, and consists of a latitude and a longitude. In practice, such a description can be used to refer to a point on Earths surface, or close to Earths surface, with the s
36、ame longitude and latitude. No provision is made in this version of the standard to give the height of a point. Figure 1 illustrates a point on the surface of the ellipsoid and its Co-ordinates. ETSI 3GPP TS 03.32 version 7.2.0 Release 1998 8 ETSI TS 101 109 V7.2.0 (2002-12) The latitude is the angl
37、e between the equatorial plane and the perpendicular to the plane tangent to the ellipsoid surface at the point. Positive latitudes correspond to the North hemisphere. The longitude is the angle between the half-plane determined by the Greenwich meridian and the half-plane defined by the point and t
38、he polar axis, measured Eastward. 5.2 E The “ellipsoid p( Figure 1: Description of a Point as two co-ordinates lipsoid point with uncertainty circle nt with uncertainty circle“ is characterised by the Co-ordinates of an ellipsoid point (the origin) and a distance r. It describes formally the set of
39、points on the ellipsoid which are at a distance from the origin less than or equal to r, the distance being the geodesic distance over the ellipsoid, i.e., the minimum length of a path staying on the ellipsoid and joining the two points, as shown in figure 2. As for the ellipsoid point, this can be
40、used to indicate points on the Earth surface, or near the Earth surface, of same latitude and longitude. The typical use of this shape is to indicate a point when its position is known only with a limited accuracy. Figure 2: Description of an uncertainty Circle ETSI 3GPP TS 03.32 version 7.2.0 Relea
41、se 1998 9 ETSI TS 101 109 V7.2.0 (2002-12) 5.3 Ellipsoid point with uncertainty ellipse The “ellipsoid point with uncertainty ellipse“ is characterised by the Co-ordinates of an ellipsoid point (the origin), distances rl and r2 and an angle of orientation A. It describes formally the set of points o
42、n the ellipsoid which fall within or on the boundary of an ellipse with semi-major axis of length rl oriented at angle A (O to 1 SO“) measure clockwise from north and semi-minor axis of length r2, the distances being the geodesic distance over the ellipsoid, i.e., the minimum length of a path stayin
43、g on the ellipsoid and joining the two points, as shown in figure 2a. As for the ellipsoid point, this can be used to indicate points on the Earths surface, or near the Earths surface, of same latitude and longitude. The confidence level with which the position of a target entity is included within
44、this set of points is also included with this shape. The typical use of this shape is to indicate a point when its position is known only with a limited accuracy, but the geometrical contributions to uncertainty can be quantified. 5.4 Figure 2a: Description of an uncertainty Ellipse Polygon A polygo
45、n is an arbitrary shape described by an ordered series of points (in the example pictured in the drawing, A to E). The minimum number of points allowed is 3, and the maximum number of points allowed is 15. The points shall be connected in the order that they are given. A connecting line is defied as
46、 the line over the ellipsoid joining the two points and of minimum distance (geodesic). The last point is connected to the first. The list of points must respect a number of conditions: - - a connecting line shall not cross another connecting line; two successive points must not be diametrically opp
47、osed on the ellipsoid. The described area is situated to the right of the lines with the downward direction being toward the Earths centre and the forward direction being from a point to the next. NOTE: This defiition does not permit connecting lines greater than roughly 20 O00 km. If such a need ar
48、ises, the polygon can be described by adding an intermediate point. Computation of geodesic lines is not simple. Approximations leading to a maximum distance between the computed line and the geodesic line of less than 3 metres are acceptable. ETSI 3GPP TS 03.32 version 7.2.0 Release 1998 10 ETSI TS
49、 101 109 V7.2.0 (2002-12) Figure 3: Description of a Polygon 5.5 Ellipsoid Point with Altitude The description of an ellipsoid point with altitude is that of a point at a specified distance above or below a point on the earths surface. This is defined by an ellipsoid point with the given longitude and latitude and the altitude above or below the ellipsoid point. Figure 3a illustrates the altitude aspect of this description. l I- Figure 3a: Description of an Ellipsoid Point with Altitude 5.6 Ellipsoid point with altitude and uncertainty ellipsoid The “ellipsoid point wi
