Method for processing location information relating to a terminal connected to a packet network via a cellular network
First Claim
1. A method (400) for processing location information, which is related to a certain mobile station in a cellular network, the method comprising the step of:
- a first network element, which is connected to the cellular network, receiving (401) a location information request (201) relating to the mobile station from a second network element, which is connected to a packet data network, requesting (404) from a third network element, which is connected to the packet data network, a security document relating to the second network element, initiating the establishment (406) of at least one security association, which security association specifies at least data origin authentication and points from the second network element to the first network element and which establishment involves use of information comprised in the security document, after successful establishment of said security association, authenticating (408) the data origin of the location service request, and if the data origin of the location service request is authenticated successfully, initiating (410) a location procedure relating to the mobile station in the cellular network.

Abstract
A method (400) for processing location information relating to a certain mobile station in a cellular network is presented. The method involves a first network element, which is connected to the cellular network, and second and third network elements, which are connected to a packet data network. The first network receives (401) a location information request (201) relating to the mobile station from a second network element. A security document relating to the second network element is requested (404) from a third network element; establishment (406) of one security association pointing from the second network element to the first network element and involving information is the security document is initiated; after successful establishment of said security association, the data origin of the location service request is authenticated (408); and after successful authentication, a location procedure relating to the mobile station in the cellular network is initiated (410). Also a network element (900), a packet data device (950) and a mobile station (901) are presented.

21. A network element (900) of a cellular network, the network element comprising
means (910) for receiving from a packet data network a location information request relating to a certain mobile station, means (920) for initiating a location procedure in the cellular network, means (930) for establishing security associations pointing to the network element from a network element of the packet data network, means (931) for performing security functions as specified by the security associations on data it receives from the packet data network, means (932) which are arranged to determine, if there is an existing security association pointing to the network element from a sender of a location information request, and means (933) for initiating security association establishment, which are arranged to establish a security association if there does not exist a security association, which points towards the network element from the sender of a location information request.
-
27. A packet data device (950) being an integral part of a mobile station or being attachable to a mobile station, comprising
means (960) for receiving information about a location information request and about a sender of a location information request from the mobile station and means (970) for exchanging with a network element connected to a cellular network information about a security association, which points to the network element from the sender of the location information request.
-
33. A mobile station (901), comprising
means for receiving a notification from a cellular network about a location information request, means for responding to the cellular network with a notification response, and means for notifying a packet data device, which is either an integral part of the mobile station or attached to the mobile station, about the location information request.
