Agenda Introduction Characteristics of a SIM Interworking with other Processes Card - Driver Man Machine Interface Mobile Network Mobility Management Generic Command Interface Error Handling Introduction Introduction SIM design: the user′s key into the GSM network via the user′s unique network identification (IMSI) GSM authentication/cipher-key algorithms tasks: User Information ADN, MS-ISDN, SMS User Management IMSI, MS ISDN Security Management secure access to the network Location Management Location Management M(obile)S(tation)=M(obile)E(quipement)+SIM SIM Characteristics Characteristics Overview GSM 02.17 GSM 900,GSM 1800 and PCS 1900 identity of the user IMSI (unambiguously identifies a subscriber) without valid IMSI MS=ME+SIM (to register onto a GSM network) primary function (in conjunction with a GSM network): to authenticate the validity of an MS when accessing the network (GSM 02.09) mandatory for any MS based on a cryptographic algorithm A3 and a secret subscriber authentication key Ki (on SIM) Characteristics Overview (cont.) SIM is limited to a passive role does not talk directly to network the ME fetches what it needs out of the SIM ECC, LP, Administrative Information, SIM Service Table, IMSI, HPLMN Search Period, PLMN selector, Location Information, Cipher Key, BCCH information, Forbidden PLMN request; ... After “login“ into the network, SIM is used “only“ for SIM presence detection Advice of Charge container for user information (ADN, SMS,SMSP, CB-MI, MSISDN,...) Characteristics Overview (cont.) physical size ID-1 SIM defined by ISO 7812-1,2 Plug-in SIM smaller than ID-1 SIM intended to be semi-permanently installed in the ME electrical interface is identical for both types of SIM Characteristics Overview (cont.) electronic signals in accordance with ISO/IEC 7812-3 unless specified otherwise supply voltage 5 V 3 V 1,8 V (e.g. used for single chip solutions) Clock speed 1- 5 MHz no internal clock, shall supplied by the ME 13/4 MHz is used -
