US 2003/0153332 A1 · Enhanced LCS privacy handling

Abstract

A system and method in a mobile communication network for providing enhanced user privacy when responding to a location request from a client requesting location information for a mobile terminal. The system includes a mobile location node, a service node serving the mobile terminal, and a home location register/home subscriber server (HLR/HSS) associated with the mobile terminal. A list of approved codewords and a list of approved service types are stored in the HLR/HSS, and only location requests that include approved codewords or service types from these lists are accepted by the system. The mobile location node may also store a list of approved service identities, and may reject location requests that do not include a service identity matching one of the approved service identities. A mapping function in the mobile location node maps service identities to service types and sends them to the HLR/HSS or to the service node for comparison with approved service types.

Dependent claims

A system in a mobile communication network for providing enhanced user privacy when responding to a location request from a client requesting location information for a mobile terminal, said network including a service node serving the mobile terminal and a home location register/home subscriber server (HLR/HSS) associated with the mobile terminal, wherein the location request includes an identifier for the requesting client, a codeword, and a service identity, said system comprising:

a mobile location node that receives the location request from the client, requests routing information from the HLR/HSS, and forwards the location request to the service node;
and
a list of approved codewords associated with the mobile terminal, said list being stored in the HLR/HSS;
wherein, the codeword included in the location request must match a codeword from the codeword list for the location request to be accepted.

receiving by the mobile location node, the location request from the client, said location request including an identifier for the requesting client, a codeword, and a service identity;
sending a request for routing information from the mobile location node to the HLR/HSS, said routing information request including the codeword from the location request;
comparing the codeword with a list of approved codewords associated with the mobile terminal, said codeword list being stored in the HLR/HSS;
and
accepting the location request only if the codeword included in the location request matches a codeword from the codeword list.
