1. A method comprising:
- receiving, at a gateway mobile location center, a request to locate a mobile terminal in a cellular network from a location service client, wherein the request includes, at least in part, an overlay identity that statically identifies the mobile terminal to an overlay network without an active context established with the mobile terminal;
causing, at least in part, a transmission of a query from the gateway mobile location center to a database, wherein the query includes, at least in part, a request for domain address information corresponding to a mobile terminal home gateway mobile location center;
causing, at least in part, a reception of the requested domain address information at the gateway mobile location center from the database;
causing, at least in part, from the gateway mobile location center a transmission of a conversion request to the mobile terminal home gateway location center for a determination of a cellular identity of the mobile terminal via a Privacy Profile Register based, at least in part, on the overlay identity;
initiating an access of a subscriber database using the cellular identity to determine routing information for the mobile terminal; and
initiating a location service of the cellular network based on the cellular identity and the routing information to provide a geographical location of the mobile terminal.

Abstract
A method and system locates a mobile terminal addressed in a location service request using an overlay identity. According to one aspect of the invention a location service client accesses a first subscriber database, thereby providing said overlay identity, in order to derive a cellular identity of said mobile terminal. According to another aspect of the invention the location service client accesses a location service server in order thereby providing said overlay identity. The location service server initiates a privacy check using said overlay identity and in response receives a cellular identity. The cellular identity then may be used to request a location service to enhance functionality.
