SYSTEM FOR IMPROVING THE HANDLING OF DEFERRED REQUESTS OF THE LOCATION OF A USER TERMINAL IN A MOBILE TELEPHONE SYSTEM

摘要

The invention related to a system for improving the handling of deferred requests of the location of a user equipement from a Location Service (LCS) client to a Location Service (LCS) server in a mobile telephone system, comprising a sender for sending, as a new parameter, a time gap within which the LCS client must receive the positioning information, to the mobile Service Switching Center (MSC), through the Gateway Mobile Location Center (GMLC); a receiver for receiving said new parameter at the Mobile Service Switching Center (MSC). The invention relates also to a method to carry out the above system, in which said time gap is sent as a new parameter specifying maximum amount of time that the LCS client waits for receiving back the location information and in that said new parameter is sent from the LCS client to MSC/SGSN via GMLC in the LCS request. It is preferred that said new parameter is sent from LCS client to GMLC and from this to MSC/SGSN modifying signalling messages already in use.
