Definitions

  • the evaluation unit which is assigned to the selected base station, again further criteria are checked.
  • these further criteria take into account, in particular, whether the evaluation unit is suitable for evaluating the signals.
  • these further criteria may take account of the resources present on the evaluation units in such a way that such evaluation units are determined to evaluate the measurements which have more resources.
  • the resources available in the respective evaluation unit are memory resources. To understand computing capacities. This makes it possible to achieve that an evaluation unit, which no longer has sufficient capacity for evaluating the measurements, by means of a other evaluation unit with higher capacity or free resources is replaced.
  • the neighborhood list it is also possible to take into account measured or modeled properties of the signal distribution around the respective base station, so that in particular those base stations which are close to the mobile object but do not receive the signal of the mobile object due to specific spatial conditions can not be included in the neighborhood list.
  • Each base station checks how large the signal strengths are according to the characteristics of the other base stations transmitted to them in comparison to the signal strength measured by themselves. If a base station determines that its measured signal strength is the largest, it declares itself as a selected base station and informs the other base stations about it, whereupon the other base stations are not allowed to declare themselves as a selected base station.
  • a particularly simple realization of the method according to the invention can be achieved if a measurement of a base station comprises a feature, measured by the respective mobile object, of a field emitted by the base station at the respective mobile object.
  • the measurements do not have to be transmitted from the base stations to the selected base station, but the features measured in the respective mobile object can be transmitted by the mobile object to the evaluation unit which is assigned to the selected base station.
  • This variant of the invention is preferably combined with the embodiment in which the selected base station is the base station associated with the mobile object. In this case, the mobile object has the information about the selected base station immediately due to the association status.
  • configuration data which are required for the evaluation of the measurements, are distributed locally to the evaluation units, so that each evaluation unit has at least those Includes configuration information, which it needs to evaluate the transmitted measurements.
  • the configuration data include in particular the relevant feature maps, signal models, the positions of the base stations in the respective neighborhood list and the like.
  • the configuration information can be used as part of a preconfiguration of the
  • the corresponding neighborhood lists can also be used to determine an evaluation unit other than based on an association be used. This can be done by using the strength of a received radio signal of the mobile object as a criterion for the selection of an evaluation unit.
  • the base station first checks whether a base station from its neighborhood list is associated with the mobile object. If this is not the case, the base station transmits its measured signal strength to all base stations from the neighborhood list. In this way, the corresponding received signal strengths of the base stations are distributed between the base stations within reach of the mobile object.

Abstract

L'invention concerne un procédé de traitement assisté par ordinateur des mesures de caractéristiques d'un réseau radio. Le réseau radio comprend une pluralité de stations de base (AP1, AP2,..., AP9) et un ou plusieurs objets mobiles (O) et des mesures sont effectuées pour un objet mobile (O) considéré. Chaque mesure est attribuée à une des stations de base (AP1, AP2,..., AP9) et décrit une caractéristique d'un champ émis par l'objet mobile (O) considéré vers la station de base (AP1, AP2,..., AP9) considérée et/ou d'un champ émis par la station de base (AP1, AP2,..., AP9) considérée vers l'objet mobile (O) considéré. Il est prévu une pluralité d'unités d'analyse (AU1, AU2,..., AU9) qui communiquent avec les stations de base (AP1, AP2,..., AP9) et chacune des unités d'analyse (AU1, AU2,..., AU9) est attribuée à une ou plusieurs des stations de base (AP1, AP2,..., AP9). Le procédé inventif se caractérise en ce que l'analyse des caractéristiques du réseau radio est effectuée par une pluralité d'unités d'analyse, une unité d'analyse adéquate étant déterminée pour analyser les caractéristiques en fonction de la position de l'objet mobile. Cette analyse distribuée des caractéristiques permet de ne pas perdre l'ensemble des informations analysées en cas de panne d'une unité d'analyse. De plus, l'utilisation de plusieurs unités d'analyse permet au procédé de disposer de suffisamment de puissance de calcul pour le traitement des mesures.
