The keys serve for user authentication and authorize the respective service access. The Equipment Identity Register (EIR) stores the serial numbers (supplied by the manufacturer) of the terminals (IMEI), which makes it possible to check for mobile stations with obsolete software or to block service access for mobile stations reported as stolen. 4 Subscriber Data in GSM Besides data of the address type, which is the most important subscriber data of any communication network, a whole series of other service- and contract-speci®c data exists in GSM networks.

The contents of such contracts are stored in appropriate data structures in order to enable correct realization or provision of these services. 7. Subscriber-related addresses are stored on the SIM and in the HLR and VLR as well. These data (IMSI, MSISDN, TMSI, MSRN) serve to address, identify, and localize a subscriber or a mobile station. 4 41 Subscriber Data in GSM data items, TMSI and MSRN are temporary values, which change according to the current location of the subscriber. Of the other data items de®ned for user or network equipment elements (like IMEI, LAI, or SPCs), only some are used (LAI, SPC) for localizing or routing.

This leaves some scope for development of future services when each subscriber may be called personally, independent of reachability or type of connection (mobile or ®xed). Besides the personal identi®er, each GSM subscriber is assigned one or several ISDN numbers. Besides telephone numbers and subscriber and equipment identi®ers, several other identi®ers have been de®ned; they are needed for the management of subscriber mobility and for addressing all the remaining network elements. The most important addresses and identi®ers are presented in the following.
