A method and apparatus for obtaining the position of a calling subscriber terminal (400) connected to a fixed IP access network (402) at an end point. A Location Information Component LIC (404) including a radio receiver (404a) is placed in the vicinity of the end point to represent the position of the terminal. Broadcasted mobile network signals or satellite navigation signals are received, and position-related information is derived from the signals and added to a data stream (Ai) from the terminal, before sending the stream over the IP access network. A centrally arranged Location Information Aggregator LIA (408) then receives the modified data stream (A2) , extracts the position-related information, and associates location information on the terminal with a network address of the end point or an identity of the terminal. Thereby, reliable location information can be obtained for calling terminals to be available to a called party or used application. |
