The present invention concerns a method for obtaining location information on the location of a terminal (UE) attached to a communication network, said method comprising the steps of: issuing, by an application (LSC CLIENT) requiring such location information, a request for location information to said communication network, forwarding said request within said network to a routing entity (VMSC, SGSN) currently in charge of routing messages for said terminal, and collecting information for determining the location of said terminal in response to said request, wherein said collecting comprises the further steps of: inquiring an access control entity (RNC) of said network currently in charge of controlling access of said terminal to said network for parameters for location determination, providing a response from said access control entity to a location determination functional entity (SMLC), judging, at said location determination functional entity (SMLC), whether the response contains said inquired parameters, and if not, asking said routing entity to provide said location determination functional entity (SMLC) with information available at said routing entity for determining the location of the terminal.
