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] |
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] |
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.

MEID
A mobile equipment identifier (MEID) is a globally unique number identifying a physical piece of CDMA2000 mobile station equipment. The number format is defined by th3GPP2 report S.R0048but in practical terms, it can be seen as an IMEI but with hexadecimal digits. An MEID is 56 bits long (14 hexadecimal digits). It consists of three fields, including an 8-bit regional code (RR), a 24-bit manufacturer code, and a 24-bit manufacturer-assigned serial number. The check digit (CD) is not considered part of the MEID. The MEID was created to replace electronic serial numbers (ESNs), whose virgin form was exhausted in November 2008. As of TIA/EIA/IS-41 Revision D and TIA/EIA/IS-2000 Rev C, the ESN is still a required field in many messages—for compatibility, devices with an MEID can use a pseudo-ESN (pESN), which is a manufacturer code of 0x80 (formerly reserved) followed by the least significant 24 bits of the SHA-1 hash of the MEID. MEIDs are used on CDMA mobile phones. GSM phone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Identification Number
The mobile identification number (MIN) or mobile subscription identification number (MSIN) refers to the 10- digit unique number that a wireless carrier uses to identify a mobile phone, which is the last part of the international mobile subscriber identity (IMSI). The MIN is a number that uniquely identifies a mobile phone working under TIA standards for cellular and PCS technologies (e.g. EIA/TIA–553 analog, IS–136 TDMA, IS–95 or IS-2000 CDMA). It can also be called the MSID (Mobile Station ID) or IMSI_S (Short IMSI). MIN derivation The mobile identification number (MIN) is a number that is derived from the 10-digit directory telephone number assigned to a mobile station. The rules for deriving the MIN from the 10-digit telephone number are given in the IS-95 standard. MIN1 is the first or least significant 24 binary digits of the MIN. MIN2 is the second part of the MIN containing the 10 most significant binary digits. MIN1, and the ESN, along with other digital input, are ...

Mobile Technology
Mobile technology is the technology used for cellular communication. Mobile technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld gaming console. Many experts believe that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers is becoming more popular. Tablets are available on the 3G and 4G networks. Mobile technology has different meanings in different aspects, mainly mobile technology in information technology and mobile technology in basketball technology, mainly based on the wireless technology of wireless devices (including laptops, tablets, mobile phones, etc.) equipment information technology integration.

Binary-coded Decimal
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow). In byte-oriented systems (i.e. most modern computers), the term ''unpacked'' BCD usually implies a full byte for each digit (often including a sign), whereas ''packed'' BCD typically encodes two digits within a single byte by taking advantage of the fact that four bits are enough to represent the range 0 to 9. The precise 4-bit encoding, however, may vary for technical reasons (e.g. Excess-3). The ten states representing a BCD digit are sometimes called '' tetrades'' (for the nibble typically needed to hold them is also known as a tetrade) while the unused, don't care-states are named , ''pseudo-decimals'' or ''pseudo-decimal digits''. BCD's main virtue, in comparison to binary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OTASP
Over-the-air programming (OTA programming) refers to various methods of distributing new software, configuration settings, and even updating encryption keys to devices like mobile phones, set-top boxes, electric cars or secure voice communication equipment (encrypted two-way radios). One important feature of OTA is that one central location can send an update to all the users, who are unable to refuse, defeat, or alter that update, and that the update applies immediately to everyone on the channel. A user could 'refuse' OTA, but the 'channel manager' could also 'kick them off' the channel automatically. In the context of the mobile content world, these include firmware-over-the-air (FOTA), over-the-air service provisioning (OTASP), over-the-air provisioning (OTAP), or over-the-air parameter administration (OTAPA); or provisioning handsets with the necessary settings with which to access services such as wireless access point (WAP) or Multimedia Messaging Service (MMS).

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 ...

3GPP2
The 3rd Generation Partnership Project 2 (3GPP2) is a collaboration between telecommunications associations to make a globally applicable third generation ( 3G) mobile phone system specification within the scope of the ITU's IMT-2000 project. In practice, 3GPP2 is the standardization group for CDMA2000, the set of 3G standards based on the earlier cdmaOne 2G CDMA technology. The participating associations are ARIB/TTC (Japan), China Communications Standards Association, Telecommunications Industry Association (North America) anTelecommunications Technology Association(South Korea). The agreement was established in December 1998. Ultra Mobile Broadband (UMB) was a 3GPP2 project to develop a fourth-generation successor to CDMA2000. In November 2008, Qualcomm, UMB's lead sponsor, announced it was ending development of the technology, favoring LTE instead. 3GPP2 should not be confused with 3GPP; 3GPP is the standard body behind the Universal Mobile Telecommunications Syste ...
