ABSTRACT:
The present invention is related to LoCation Services (LCS) in General Packet Radio Service (GPRS). Because the specification of LCS was missing in the first versions of the technical specifications of GPRS, but already introduced in the GSM specifications, there will be a number of MSs having LCS capabilities when attached to circuit switched serving nodes (MSCs) but not when attached to packet switched serving nodes (SGSNs). When a location request for one such MS attached to both an MSC and an SGSN is directed to the SGSN first, an error may occur. The present invention discloses a method solving this problem by informing the associated HLR if the MS supports location service in packet switched mode or not at the time the MS attaches the network. The information is stored in the HLR, and when the location service node in the network receives a location request for that MS, the location node invokes the HLR for the information. If the MS does not support location service in packet switched mode, the HLR informs the location service node to firstly request the MS attached MSC for the location of the MS.
