Abstract

The present invention discloses a method for processing a location information request in a location service, comprising: a location information request initiator sending a location information request containing a processing indication to a location information request receiver; after receiving the location information request, the location information request receiver determining whether to perform synchronous processing or asynchronous processing for the location information request according to type of the processing indication, and then implementing corresponding processing for the location information request. This method is capable of effectively saving system resource of a LCS system, avoiding resource waste at a location service interface and increasing processing performance of a location service.
