EIR - the register of identification of the equipment, contains the centralized database for confirmation of authenticity of the international identification number of the equipment of mobile station (IMEI). This database belongs only to the equipment of mobile station.
The RAP profile is developed for systems of a subscriber radio access (WLL) on the basis of the DECT technology. RAP defines protocols and methods of rendering of services of public networks to end users with use of the DECT technology. RAP defines two types of service:
As well as in a case about HLR, a network can have more than one EIR, thus each EIR operates certain groups IME B a part of MSC the translator which when obtaining number IMEI returns the address EIR operating the corresponding part of a database about the equipment is.
This profile is closely connected with computer technology, in particular laptops. Therefore for ensuring compatibility and simplification of access in the terminal the client of CAPI (v is emulated. 1/, and in a base station — the SAR server
Each mobile subscriber for the period of use of a communication system receives the standard module of authenticity of the subscriber (SIM) which contains: international identification number (IMSI), the individual key of authentication (Ki), algorithm of authentication (A.
For creation of networks of access on the basis of the DECT technology the profile of access to networks of mobile terminals (STM) is defined. STM provides roaming of terminals between networks of access of the DECT. In places where the radio covering of the DECT with system (house, office is provided or public), wireless phone can serve as entering, and outcoming calls. Thus the mobile terminal is registered only in one system with one telephone number. Thus, communication in any place where there is a DECT system is provided. And for the terminal in all networks the same network number therefore the entering calls are not lost remains.
DMAP is developed first of all for the organization of wireless access to the Internet networks through ISDN networks and maintenance of speech terminals and terminals of data transmission of the DECT. Therefore DMAP is based on the ISDN, GAP and DSP protocols.
To the data containing in HLR all MSC and VLR networks and if in a network there are some HLR have remote access, the database contains only one record about the subscriber therefore each HLR represents a certain part of the general database of a network about subscribers. Access to a database about subscribers is provided according to number IMSI or MSISDN (to number of the mobile subscriber in the ISDN network). Can get access of MSC or VLR to a database, belonging to other networks, within ensuring gateway roaming of subscribers.
NMC can take the responsibility in any region when local compulsory health insurance is unattended, at this compulsory health insurance works as transit point between NMC and the equipment of a network. NMC provides operators with the functions similar to the compulsory health insurances functions.
Within this profile the organization of standard channel structure 2B+D of basic access of ISDN by allocation of 5 traffic DECT channels is possible. Thus the DECT provides the standard network termination of ISDN with the SO interface. Advantage of this profile is possibility of use of any standard ISDN terminal, including data transmission terminals.
For safety of the data which are in HLR and VLR in case of failures protection of devices of memory of these registrov.vlr is provided contains the same data, as well as HLR, however these data contain in VLR only until the subscriber is in the zone controlled by VLR.
In a network of mobile communication of GSM honeycombs are grouped in geographical zones (LA) to which the identification number (LAC) is assigned. Each VLR contains data on subscribers in several LA. When the mobile subscriber moves from one LA to another, data on his location are automatically updated in VLR. If old and new LA are under control of various VLR, data on old VLR are erased after their copying in new VLR. The current address VLR of the subscriber containing in HLR is also updated.
