CSIM
A CDMA subscriber identity module (CSIM) is an application to support CDMA2000 phones that runs on a UICC, with a file structure derived from the R-UIM card. By porting the application to the UICC (Universal Integrated Circuit Card), a card with CSIM, SIM, and USIM can operate with all major cellular technologies worldwide. The CSIM application allows users to change phones by simply removing the smart card from one mobile phone and inserting it into another mobile phone or broadband telephony device supporting the CDMA2000 radio interface.C.S0065-B v2.0.

EUIMID
EUIMID (expanded UIMID) is a unique identifier for an R-UIM (Removable User Identity Module) or CSIM (CDMA SIM application) card in CDMA2000 cellular systems that replaces the older UIMID identifier. There are two forms of EUIMID, known as Short Form (SF_EUIMID) and Long Form (LF_EUIMID). Both produce a 32-bit pseudo- UIMID (pUIMID) with 0x80 in the upper 8 bits and the least significant 24 bits of the SHA-1 hash of the entire SF_EUIMID or the entire ICCID EF (for LF_EUIMID) in the lower 24 bits. The EUIMID (and UIMID) are hardware identifiers that do not change throughout the life of the card they identify. Their most important characteristic is that they are globally unique, no two R-UIM or CSIM cards should ever be given the same number. Secondly, they can identify the issuer of the code (likely a mobile phone operator in the case of LF_EUIMID, and an R-UIM or CSIM card manufacturer in the case of SF_EUIMID). The pseudo-UIMID is not unique, but can satisfy most uses of U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The UICC ensures the integrity and security of all kinds of personal data, and it typically holds a few hundred kilobytes. The official definition for UICC is found in ETSI TR 102 216, where it is defined as a "smart card that conforms to the specifications written and maintained by the ETSI Smart Card Platform project". In addition, the definition has a note that states that "UICC is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

UIMID
A UIMID (user identity module identifier) is a 32-bit Electronic Serial Number (ESN) stored in a R-UIM or CSIM ('smart card') used for TDMA or CDMA2000 phones (mainly the latter). It is given a different name to avoid confusion with the hardware ESN stored in the phone. In all known systems the UIMID displaces the ESN in signaling (based on setting bit 1 of the 'UsgInd' field to '1' in the card). Because the UIMID is allocated from the same numbering space as ESN its existence is transparent to the network. The reason the UIMID is transmitted instead of the ESN is because the card contains the MIN or IMSI and devices such as the HLR running the Asbi mobility management protocol insist on a static association between these identifiers for subscription validation. The HLR will store the MIN or IMSI alongside the ESN in each record, and if an ANSI-41 message is received containing a different pair it will be rejected as invalid. UIMID codes are allocated by the TIA using indust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CDMA2000
CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G mobile technology standards for sending voice, data, and Signaling (telecommunication), signaling data between mobile phones and cell sites. It is developed by 3GPP2 as a backwards-compatible successor to 2G, second-generation cdmaOne (IS-95) set of standards and used especially in North America and South Korea. CDMA2000 compares to UMTS, a competing set of 3G standards, which is developed by 3GPP and used in Europe, Japan, China, and Singapore. The name CDMA2000 denotes a family of standards that represent the successive, evolutionary stages of the underlying technology. These are: *Voice: CDMA2000 1xRTT, 1X Advanced *Data: CDMA2000 1xEV-DO (Evolution-Data Optimized): Release 0, Revision A, Revision B, Ultra Mobile Broadband (UMB) All are approved radio interfaces for the International Telecommunication Union, ITU's IMT-2000. In the United States, ''CDMA2000'' is a registered trademark of the Tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CdmaOne
Interim Standard 95 (IS-95) was the first ever CDMA-based digital cellular technology. It was developed by Qualcomm and later adopted as a standard by the Telecommunications Industry Association in TIA/EIA/IS-95 release published in 1995. The proprietary name for IS-95 is cdmaOne. It is a 2G mobile telecommunications standard that uses code-division multiple access (CDMA), a multiple access scheme for digital radio, to send voice, data and signaling data (such as a dialed telephone number) between mobile telephones and cell sites. CDMA transmits streams of bits ( PN codes). CDMA permits several radios to share the same frequencies. Unlike TDMA "time division multiple access", a competing system used in 2G GSM, all radios can be active all the time, because network capacity does not directly limit the number of active radios. Since larger numbers of phones can be served by smaller numbers of cell-sites, CDMA-based standards have a significant economic advantage over ...

Short Message Service
Short Message/Messaging Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile devices exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines. SMS technology originated from radio telegraphy in radio memo pagers that used standardized phone protocols. These were defined in 1986 as part of the Global System for Mobile Communications ( GSM) series of standards.GSM Doc 28/85 "Services and Facilities to be provided in the GSM System" rev2, June 1985 The first SMS message was sent on 3 December 1992, when Neil Papworth, a test engineer for Sema Group, sent "Merry Christmas" to the Orbitel 901 phone of colleague Richard Jarvis. SMS rolled out commercially on many cellular networks that decade and became hugely popular worldwide as a method of text communication. By the end of 2010 ...

International Mobile Subscriber Identity
The international mobile subscriber identity (IMSI) is a number that uniquely identifies every user of a cellular network. It is stored as a field and is sent by the mobile device to the network. It is also used for acquiring other details of the mobile in the home location register (HLR) or as locally copied in the visitor location register. To prevent eavesdroppers from identifying and tracking the subscriber on the radio interface, the IMSI is sent as rarely as possible and a randomly-generated TMSI is sent instead. The IMSI is used in ''any'' mobile network that interconnects with other networks. For GSM, UMTS and LTE networks, this number was provisioned in the SIM card and for cdmaOne and CDMA2000 networks, in the phone directly or in the R-UIM card (the CDMA equivalent of the SIM card). Both cards have been superseded by the UICC. An IMSI is usually presented as a 15-digit number but can be shorter. For example, MTN South Africa's old IMSIs that are still in use i ...

Temporary Mobile Subscriber Identity
Mobility management is one of the major functions of a GSM or a UMTS network that allows mobile phones to work. The aim of mobility management is to track where the subscribers are, allowing calls, SMS and other mobile phone services to be delivered to them. Location update procedure A GSM or UMTS network, like all cellular networks, is basically a radio network of individual cells, known as base stations. Each base station covers a small geographical area which is part of a uniquely identified location area. By integrating the coverage of each of these base stations, a cellular network provides a radio coverage over a much wider area. For GSM, a base station is called a base transceiver station (BTS), and for UMTS it is called a Node B. A group of base stations is named a location area, or a routing area. The location update procedure allows a mobile device to inform the cellular network whenever it moves from one location area to the next. Mobiles are responsible for dete ...
