  • an emergency call e.g. of E-91 1 type in use in North America
  • SIM Subscriber Identity Module
  • the invention can be applied to both GSM and UMTS technologies, and in the context of both Circuit Switch (CS) and Packet Switch (PS) .
  • CS Circuit Switch
  • PS Packet Switch
  • the Gateway Mobile Location Center implements functionalities required to support the Location Services LCS.
  • Each GMLC is the first node for the accesses of an external LoCation Services Client (LCS Client) in a mobile network.
  • the GMLC may request routing information from a global register - Home Location Register (HLR) or Home Subscriber Server (HSS) - of the subscribers of the operator.
  • HLR Home Location Register
  • HSS Home Subscriber Server
  • the GMLC contains information allowing to perform authentication and authorization activities of external LCS Client entities requiring location of mobile users.
  • the GMLC After having obtained the routing information and performed the authorization and authentication activities of the external LCS Clients, the GMLC sends the location request to the Mobile Switching Center/Visitor Location Register (MSC/VLR) or Serving GPRS Support Node (SGSN) and receives information about the geographic coordinates of the mobile user terminal whose location has been requested from the corresponding entities.
  • MSC/VLR Mobile Switching Center/Visitor Location Register
  • SGSN Serving GPRS Support Node
  • the HLR/HSS register contains all subscription user data, including the LCS subscription user data, and routing information.
  • the HRL/HSS may be in a network different from the one he is currently roaming into. In other words, should the user be roaming in the network of an operator different from the one he subscribes to, the HLR/HSS register is always the one of the operator the user subscribes to.

  • the LCS functions of MSC/VLR and SGSN are related to charging and billing, coordination, location request, authorization and operation of the LCS services.

  • figs. 4 and 5 represent the main signalling between nodes when the positioning system according to the invention is adopted, for the initial location and the updated location of the subscriber, respectively.
  • the LCS client may ask to know (fig. 3) the updated UE location by means of MT-LR without HLR query procedure.
  • the VMSC identifies the target UE using IMSI, MSISDN or NA-ESRK and, if provided, IMEI.
  • IMSI IMSI
  • MSISDN MSISDN
  • NA-ESRK NA-ESRK
  • IMEI a non-dialable call back number derived from the IMEI can be used, in place of MSISDN, in order to reach the subscriber.
  • the emergency service routing key (e.g. the already mentioned NA- ESRK using number 91 1 ) is not always available and is not supported in the MAP message "PROVIDE SUBSCRIBER LOCATION" (see fig. 3); the non-dialable call-back number used in place of MSISDN is then made of 91 1 + the last 7 digits of IMEI and does not identify the subscriber in an univocal manner. In fact, e.g., two subscribers having the same last 7 digits of the IMEI would have the same non- dialable call-back number.
  • IMEI is non mandatory in the MAP messages being used.
  • the basic idea of the present invention is to overcome the problem described in the previous paragraphs by providing a mechanism which allows the VMSC and GLMC to univocally identify the subscriber involved in the positioning procedure, even in case the emergency call is performed by a mobile phone without a SIM or with an unvalid SIM and neither the IMSI nor the MSIDSN as dialable call-back number are available.
  • the invention relates to a system for univocally identifying a mobile subscriber during an emergency call performed by a mobile phone without a SIM card or with an unvalid SIM card, to determine its updated geographic position, characterised in that, in messages of the positioning procedure, international mobile equipment identity (IMEI) is used to univocally discriminate the subscribers to be positioned during an emergency call in case they have the same non-dialable call back number, said international mobile equipment identity (IMEI) being made mandatory in said messages when both international mobile subscriber identy (IMSI) and mobile subscriber ISDN number (MSISDN) are not available as dialable call back number.
  • IMEI international mobile equipment identity
  • IMSI international mobile subscriber identy
  • MSISDN mobile subscriber ISDN number
  • the invention relates also to a method to carry out said system, which provides: that the mobile switching center (MSC) or visitor location register (VLR) or serving GPRS support node (SGSN) sends mandatorily the subscriber international mobile equipment identity (IMEI) to gateway mobile location center (GMLC) at notification of the initial geographic position of the subscriber; that the gateway mobile location center (GMLC) discriminates two or more subscriber through the subscriber international mobile equipment identity (IMEI) received from the mobile switching center (MSC) or visitor location register (VLR) or serving GPRS support node (SGSN) when the mobile subscriber ISDN number (MSISDN) of different users carries the same non-dialable call back number and the emergency service routing key (as, for example NA-ESRK) is not available; that the gateway mobile location center (GMLC) sends mandatorily the international mobile identity (IMEI) of the subscriber which updated geographic position is requested, during the emergency call, to the mobile switching center (MSC) or visitor location regiser (VLR) or serving GPRS
  • the invention refers to a computer program loadable in a memory apt to perform the steps of the above method.
  • the invention implies that the IMEI is used as a mandatory parameter in the MAP messages
  • BERJ-OCATION (see fig. 3), in case neither the IMSI nor the MSISDN are available as dialable call-back number.
  • the invention is shown applied in Figs. 4 and 5 of the enclosed drawings, see the message 7 of Fig. 4 and the message 2 of Fig. 5.
  • Fig. 4 it is shown, in fact, that - when a location request induced by NI-LR network is performed because of an emergency call - IMEI is, according to the invention, mandatory in the MAP message "SUBSCRIBERJ_OCATION_REPORT" (message 7 of Fig. 4), if neither IMSI nor MSISDN (in form of dialable call-back number) are message 7 available.
  • MSC/VLR or SGSN sends IMEI to GMLC, as a mandatory parameter, at the notification of the initial geographic position of the subscriber, through the map message
  • IMEI is used ad a mandatory parameter in the MAP message "PROVIDED SUB- SCRIBER_LOCATION_REPORT" (message 2 of Fig. 5), during the MT-LR, without the HLR Query procedure.
  • GMLC sends mandatorily the IMEI of the subscriber to MSC/VLR or SGSN during the updating procedure of the geographic position of the subscriber, through the message "PROVIDE_SUBSCRIBERJ_OCATION" .
  • MSISDN as a non dialable call-back number
  • the VMSC uses the IMEI to identify the call and the related subscriber to be positioned.
  • the present invention allows in any case the univocal and updated positioning, during an emergency call performed by a mobile phone without a SIM card or with an unvalid SIM card, without any ambiguity on the mobile phone to be positioned, both in the GMLC and VMSC.

Abstract

L'invention se rapporte à un système d'identification univoque d'un abonnée mobile au cours d'un appel d'urgence passé depuis un téléphone mobile sans carte SIM ou avec une carte SIM non valide, afin de déterminer sa position géographique mise à jour. Ce système se caractérise par le fait que, dans les messages de procédure de positionnement, l'identité internationale d'équipement mobile (IMEI) sert à différencier de manière univoque les abonnés qui doivent être localisés au cours d'un appel d'urgence au cas où ils possèdent le même numéro de rappel impossible à composer, ladite identité internationale d'équipement mobile (IMEI) étant impérative dans ces messages lorsqu'à la fois l'identité internationale d'abonné mobile (IMSI) et le numéro ISDN de l'abonné (MSISDN) ne sont pas disponibles en tant que numéros de rappel pouvant être composés.
