Abstract
Disclosed herein is a method useful for target user equipment (UE) sending a location report. When the target UE is located in a first central network (CN) of a location service (LCS) system the target UE reports the location report to the LCS system. If the target UE does not receive a location report response from the LCS system when being located in a second CN of LCS system target UE will continue to report the location report to LCS system. In accordance with one aspect of the disclosed method the waste of location service system resource is avoided as well as the execution efficiency of location service is increased. In addition during procedure of change of area event location request the consequent processing of request thereof is guaranteed to be normal so that execution efficiency of location service is increased. Moreover message interaction between the function entities is saved for the exception cases. Accordingly the waste of public land mobile communication network resource caused by generation of excessive useless messages is avoided.
