The MTPAS access class may be indicated on the SIM card, or in protected storage on the handset itself, by a set of numbers in the range 0 - 15, giving a total of 16 flag bits in the Access Control Class Elementary File (EFACC) in a USIM. For instance, if the 16-bit control word is 1010-0000-0011-1111, only phones with the MTPAS access levels ...
Reliable access to the mobile networks, even during times when an exceptionally large number of calls are being made, is achieved by installing a special SIM (subscriber identity module) card in the telephone handset. Special SIMs are only available to entitled users within the emergency services community, and not to members of the public.

A Secure Access Module (SAM), also known as a Secure Application Module, is a piece of cryptographic hardware typically used by smart card card readers to perform mutual key authentication. [ 1 ] [ 2 ] [ 3 ] SAMs can be used to manage access in a variety of contexts, such as public transport fare collection and point of sale devices.
SIM Application Toolkit (STK) is a standard of the GSM system which enables the subscriber identity module (SIM card) to initiate actions which can be used for various value-added services. [1] Similar standards exist for other network and card systems, with the USIM Application Toolkit (USAT) for USIMs used by newer-generation networks being ...
Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously ...
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
