摘要

A method and system for location service and CSN(Connectivity Service Network) are provided in the present invention. The method includes: a home domain CSN(H-CSN) receiving a location request sent by a client end; the location request being sent to visit domain CSN(V-CSN) after the location request is authenticated successfully; receiving a location result returned from the V-CSN, and the location result being the information obtained from location measurement by triggering the visit domain ASN(V-ASN) after the V-CSN sends the location request to the V-ASN; and sending the location result to the client end.
