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.

Abstract: A system and method in a mobile communication network for providing enhanced user privacy when responding to a location request from a client requesting location information for a mobile terminal. The system includes a mobile location node, a service node serving the mobile terminal, and a home location register/home subscriber server (HLR/HSS) associated with the mobile terminal. A list of approved codewords and a list of approved service types are stored in the HLR/HSS, and only location requests that include approved codewords or service types from these lists are accepted by the system. The mobile location node may also store a list of approved service identities, and may reject location requests that do not include a service identity matching one of the approved service identities. A mapping function in the mobile location node maps service identities to service types and sends them to the HLR/HSS or to the service node for comparison with approved service types.
