If it does not belong, it returns a positioning failure response to the area restricted requester. The failure response carries an error cause value, and refuses to provide the location information of the target UE to the restricted requesting end.
  • the H-GMLC After the H-GMLC receives the positioning result information of the target UE forwarded by the V-GMLC, the H-GMLC can further determine whether to provide the target UE with the target UE based on the obtained location information of the target UE and the effective geographical range of the geographically restricted requester. Location information, processing and the above process basically the same.
  • the effective geographical range of the geographically restricted requester is compared with the address information of the CN where the target UE is currently located and the location information of the target UE, the effective geographical range must be unified with the representation method of the CN address information and the location information of the target UE. Therefore, after the target UE determines its effective geographical range for the geographically restricted requesting end, the LCS system will convert the effective geographical range into a geographical range consistent with the representation method of CN address information and target UE location information.

Abstract

La présente invention a trait à un procédé de demande d'information de localisation de zone à accès limité, concernant le positionnement technique d'équipement de réseau, dans lequel un client de service de localisation initie une demande auprès d'un système d'information de localisation pour une requête d'information de localisation d'un équipement d'utilisateur visé, au cours du traitement du système de service de localisation, le procédé comprenant: la détermination par le système de service de localisation si la requête d'information de localisation initiée par le client de service de localisation est une requête d'information de localisation de zone à accès limité, si la requête d'information de localisation est une requête concernant une zone à accès limité, le système de service de localisation refuse de fournir l'information de localisation de l'équipement d'utilisateur concerné, et si ce n'est pas une requête d'information de localisation concernant la zone à accès limité, le système de service de localisation renvoie l'information de localisation de l'équipement d'utilisateur concerné au client de service de localisation, et met fin au traitement en cours de la requête d'information de localisation. Selon le procédé de la présente invention, cela permet le contrôle approprié par l'équipement d'utilisateur concerné de la fourniture à des tiers de sa propre information de localisation. En outre, la présente invention permet à l'équipement d'utilisateur concerné d'établir différentes restrictions d'étendues de zone pour différentes requêtes de limitation, et améliore la flexibilité du service de localisation.
