Definitions

  • the present invention relates to a system which reduces costs of identifying IMSI (International Mobile Subscriber Identifier) numbers to GSM (Global System for Mobile Communications) systems.
  • IMSI International Mobile Subscriber Identifier
  • GSM Global System for Mobile Communications
  • SIM cards Before distributing the new SIM cards to their subscribers, operators first identify these SIM cards to the GSM systems and then distribute the cards to the dealers. In this situation, if the numbers desired by the subscribers are not available at that dealer, the subscriber has to go to another dealer or purchase another number apart from the number that s/he desires. In order to solve this problem, after the SIM cards identified to the GSM systems are sent to the dealers, the information (IMSI) in the SIM card is changed in accordance with the number desired by the subscriber and they are re-identified to the GSM system.
  • IMSI information
  • the Chinese patent document CN 1444414 in the state of the art discloses a method wherein subscribers can change the IMSI codes by their own telephones.
  • US5765105 discloses a system which enables the same IMSI number to be used in a plurality of mobile devices.
  • the United States patent document US6556820 discloses a system which uses a single TMSI (temporary mobile subscriber identification) number.
  • TMSI temporary mobile subscriber identification
  • authentication of a SIM card is postponed if there is an ongoing authentication process of another SIM card at the same time.
  • IMSI codes In order for the desired numbers to be identified to the SIM card over the air, there need to be dummy IMSI codes in the SIM cards and the said codes should be identified to the GSM system. Operators intend to identify a specific IMSI series to new SIM cards by using it cyclically, with the purpose of reducing the cost of identifying these IMSI codes, which are going to be used only during subscription phase, to the GSM system.
  • the objective of the present invention is to realize a system which uses the IMSI numbers in the SIM cards, which are stored by the GSM operators to distribute new SIM cards, cyclically to reduce the costs of identifying these temporarily used IMSI numbers to the GSM systems.
  • Another objective of the present invention is to realize a system wherein the number of dummy IMSI codes, which are provided to the field in SIM card subscriptions made OTA (Over The Air) by the operators, is reduced.
  • a further objective of the invention is to realize a system wherein the identification costs in HLR (Home Location Register) are reduced by preventing a dummy IMSI code from connecting to the network while another dummy IMSI code whose SIM card is sold is being processed.
  • Another objective of the invention is to realize a system wherein the dummy IMSI codes are replaced with real IMSI codes as soon as the SIM card is sold and thus the unique IMSI code is enabled to circulate within the network.
  • Figure 1 is the block diagram of the inventive system.
  • FIG. 1 is the flowchart of the inventive system.
  • SCPC SIM Card Personalization Center
  • HLR Home Location Register
  • the inventive system (1) essentially comprises a device (2) having a SIM card (21), an EIR unit (3), a SIM card personalization center (4), an HLR (5) and CAS systems (6).
  • the device (2) is a mobile phone.
  • the inventive system (1) in order for the subscription operations to be carried out in the field via OTA (Over the Air), the dummy IMSI codes are cyclically identified to the SIM cards (21) by the SIM card producer.
  • the EIR unit (3) which is the location in the network where the initial control of IMSI in addition to IMEI (International Mobile Equipment Identity) is performed, is customized.
  • the inventive system (1) operates with the steps of
  • the device (2) transmitting the dummy IMSI code of the SIM card (21) to the EIR unit (3) by sending "checklMEI” message to the EIR unit (3) (102),
  • EIR unit (3) receiving the dummy IMSI code of the SIM card (21) and blocking use of this IMSI code by devices with other IMEIs until activation of the SIM card (21) is completed (103),
  • EIR unit (3) transmitting to the SIM card personalization center (4) the information of detection of a new SIM card (21) and the dummy IMSI information of the said card (21) (104),
  • SIM card personalization center (4) prompting the device (2) for the serial number of the SIM card (21) by using the IMSI information transmitted thereto (105),
  • the SIM card personalization center After obtaining the serial number of the SIM card (21), the SIM card personalization center (4) requesting from the CAS systems (6) the real MSISDN and real IMSI codes corresponding to the serial number of the SIM card (21) (106),
  • the SIM card personalization center After obtaining the real MSISDN and real IMSI codes, the SIM card personalization center (4) sending the real IMSI code to the device (2) and writing it into the SIM card (21) (107), SIM card personalization center (4) reporting to the HLR the real MSISDN code assigned to the real IMSI (108),
  • the EIR unit (3) deallocating the dummy IMSI code for use by different IMEIs (110). e system (1),

  • the EIR unit (3) receives the concerned IMSI information from within the "checkJMEI" message transmitted thereto during activation, blocks use of this IMSI by other IMEIs for a period of time, and transmits the concerned IMSI information to the SIM card personalization center (4).
  • SIM card personalization center (4) prompts the SIM card (21) for the serial number by using the IMSI information transmitted thereto.

  • IMSI codes corresponding to the SIM card (21) are found from the CAS systems (6) and written into the SIM card (21).
  • the concerned dummy IMSI lock on the EIR unit (3) is removed and activation of the other SIM cards having the same IMSI is allowed.
  • the identification costs in HLR are reduced by preventing a dummy IMSI code from connecting to the network while another dummy IMSI code whose SIM card is sold is being processed.
  • the dummy IMSI codes are replaced with real IMSI codes as soon as the SIM card is sold and thus the unique IMSI code is enabled to circulate within the network.
