Patent

CA 2711856

Techniques for supporting location services in a user plane location architecture such as Secure User Plane Location (SUPL) are de- scribed. In an aspect, a terminal informs a location server of service capa-bilities of the terminal. The location server uses the service capabilities to request only location services supported by the terminal and to avoid re- questing unsupported location services. The terminal generates a message containing its service capabilities and sends the message via a user plane, e.g., SUPL. The location server receives the message, obtains the service capabilities of the terminal, and stores these service capabilities for future network-initiated location sessions with the terminal. The location server determines whether a location service is supported by the terminal based on the service capabilities of the terminal. The location server communicates with the terminal via the user plane for the location service if supported by the terminal.

Des techniques pour supporter des services de localisation dans une architecture de localisation de plan d'utilisateur telle que la localisation de plan d'utilisateur sécurisée (SUPL) sont décrites. Dans un aspect, un terminal informe un serveur de localisation des capacités de service du terminal. Le serveur de localisation utilise les capacités de service pour envoyer des demandes uniquement aux services de localisation supportés par le terminal et pour éviter d'envoyer des demandes à des services de localisation non supportés. Le terminal génère un message contenant ses capacités de service et envoie un message via un plan d'utilisateur, par exemple SUPL. Le serveur de localisation reçoit le message, obtient les capacités de service du terminal, et stocke ces capacités de service pour des sessions ultérieures de localisation initiées par le réseau avec le terminal. Le serveur de localisation détermine si un service de localisation est supporté par le terminal à partir des capacités de service du terminal. Le serveur de localisation communique avec le terminal via le plan d'utilisateur pour le service de localisation s'il est supporté par le terminal.
