In GSM networks, the SIM Application Toolkit is defined by the GSM 11.14 standard released in 2001. [1] [4] [6] From release 4 onwards, GSM 11.14 was replaced by 3GPP TS 31.111 which also includes the specifications of the USIM Application Toolkit for 3/4G networks. [2]
MAP for GSM (prior to Release 4) is specified by 3GPP TS 09.02 (MAP v1, MAP v2) MAP for UMTS ("3G") and GSM (Release 99 and later) is specified by 3GPP TS 29.002 (MAP v3) In cellular networks based on ANSI standards (currently CDMA2000 , in the past AMPS , IS-136 and cdmaOne ) plays the role of the MAP a similar protocol usually called IS-41 or ...
GSM procedures are sets of steps performed by the GSM network and devices on it in order for the network to function. GSM (Global System for Mobile Communications) is a set of standards for cell phone networks established by the European Telecommunications Standards Institute and first used in 1991.
In the GSM mobile phone system, in contrast with earlier analogue services, fax and data information is sent digitally encoded directly to the MSC. Only at the MSC is this re-coded into an "analogue" signal (although actually this will almost certainly mean sound is encoded digitally as a pulse-code modulation (PCM) signal in a 64-kbit/s ...

A SIM lock, simlock, network lock, carrier lock or (master) subsidy lock is a technical restriction built into GSM and CDMA [1] mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks.
In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance.
