Patent ID: 7321775

Claim:
A method, comprising: issuing, by an application requiring location information on the location of a terminal attached to a communication network, a request for location information to said communication network; forwarding said request within said network to a routing entity currently in charge of routing messages for said terminal; and collecting information to determine the location of said terminal in response to said request, wherein said collecting comprises inquiring an access control entity of said network currently in charge of controlling access of said terminal to said network for parameters for location determination by calculation of the location using the inquired parameters, providing a response from said access control entity to a location determination functional entity, judging, at said location determination functional entity, whether the response contains said inquired parameters, and when the response does not contain said inquired parameters, asking said routing entity to provide said location determination functional entity with information available at said routing entity for determination of the location of the terminal by mapping the provided available information to coordinate information, wherein the mapping of the provided available information of the coordinate information comprises comparing the provided available information with information on antenna locations kept in a network management/planning system and determining location information on the location of said terminal based on the collected information, wherein the location of the terminal is determined with higher accuracy when the inquired parameters are received as compared to being not based on the inquired parameters, wherein the method is configured to obtain the location information.
