(U)SIM Interface
The (U)SIM interface is the connecting point of the mobile phone and the Universal integrated circuit card, UICC with its Subscriber Identity Module, SIM or Universal Subscriber Identity Module, USIM application. Standardisation of the (U)SIM interface The UICC with the SIM or USIM application plays an important role in mobile telephony as it is the secure element identifying a subscriber in the network and allowing Mobile network operator, MNOs to bill the respective account. Hence it is crucial to have standardised features e.g. placing phone calls or sending SMS working throughout the global network with all available handsets and (U)SIM cards resp. UICCs. Developing globally applicable standards for communication technologies is the task of standardisation bodies such as ETSI (European Telecommunications Standards Institute, 3GPP (Third Generation Partnership Project) and 3GPP2 (Third Generation Partnership Project 2). In case of the (U)SIM interface, the most important specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Phone
A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called ''cellular telephones'' or ''cell phones'' in North America. In addition to telephony, digital mobile phones ( 2G) support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Integrated Circuit Card

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] |

Mobile Network Operator
A mobile network operator (MNO), also known as a wireless service provider, wireless carrier, cellular company, or mobile network carrier, is a provider of wireless communications services that owns or controls all the elements necessary to sell and deliver services to an end user, including radio spectrum allocation, wireless network infrastructure, back haul infrastructure, billing, customer care, provisioning computer systems, and marketing and repair organizations. Operator In addition to obtaining revenue by offering retail services under its own brand, an MNO may also sell access to network services at wholesale rates to mobile virtual network operators (MVNO). A key defining characteristic of a mobile network operator is that an MNO must own or control access to a radio spectrum license from a regulatory or government entity. A second key defining characteristic of an MNO is that it must own or control the elements of the network infrastructure necessary to provide se ...

ETSI
The European Telecommunications Standards Institute (ETSI) is an independent, not-for-profit, standardization organization in the field of information and communications. ETSI supports the development and testing of global technical standards for ICT-enabled systems, applications and services. Overview ETSI was set up in 1988 by the European Conference of Postal and Telecommunications Administrations ( CEPT) following a proposal from the European Commission. ETSI is the officially recognized body with a responsibility for the standardization of Information and Communication Technologies (ICT). It is one of the three bodies, the others being CEN and CENELEC, officially recognized by the European Union as a European Standards Organization (ESO). The role of the European Standards Organizations is to support EU regulation and policies through the production of Harmonised European Standards and other deliverables. The standards developed by ESOs are the only ones that can be rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 System (U ...

Global Certification Forum
The Global Certification Forum, known as GCF, is an active partnership between mobile network operators, mobile device manufacturers and the test industry. GCF was founded in 1999, and its membership has been responsible for creating an independent certification programme to help ensure global interoperability between mobile devices and networks. The GCF certification process is based on technical requirements as specified within dedicated test specifications provided by the 3GPP, 3GPP2, OMA, IMTC, the GSM Association and others. The current GCF membership includes mobile network operators, more than 40 leading terminal manufacturers and over 65 test equipment manufacturers, test laboratories and other organizations from mainly a test environment. Recognized Test Organizations Recognised Test Organisations (RTO) are GCF Members that have demonstrated they possess the experience, qualifications and systems to assess mobile phones and wireless devices against GCF's Certification C ...

CDMA Certification Forum
CDMA Certification Forum (known as CCF) was the original official authority governing CDMA Device certification. The CCF is an international partnership between network operator and device vendors to maintain and evolve a core global device certification process that helps improve quality through consistent interoperability, conformance and performance testing across the globe. On 31 December 2014, CCF voted to hand all its certification responsibilities to the Global Certification Forum (GCF). History *July 2004: The CDMA Certification Forum was established as a nonprofit 501(c) organization, with the purpose of defining and implementing a core global handset certification process for cellular phones and terminals using CDMA technology. *October 2006: Washington, DC – CTIA adopts the CCF test plan for CDMA device certification *February 2008: Costa Mesa, CA – The CDMA Development Group (CDG) recognizes the CCF as the sole device certification authority and transfers its reco ...
