Whereas the SIM is commonly seen as the physical card together with the software to authenticate, authorize, and identify the subscriber, the UICC merely defines the physical characteristics of the smart card. The USIM and ISIM are software applications resident on the UICC. Legally, the UICC remains a property of the mobile network operator who has the authority to decide which applications can reside on it, such as USIM and ISIM. Each operator can use the card as a network endpoint independently from the mobile phone. The UICC is the port of call within each mobile device where mobile operators can store the applications that bring their services to fruition, such as for roaming, branding, device tracking, and browsers. Storing such applications in the UICC means that they benefit from the UICCs’ security credentials, thus offering revenue protection for the operator. Being removable, it is easy to transfer them when devices are renewed without the need to rewrite the application.
Introduction to Mobile Multimedia
Published in Amitabh Kumar, Mobile Broadcasting with WiMAX: Principles, Technology, and Applications, 2014
Large storage is now a common feature of all smartphones and mobile devices, demonstrated in no better manner than the iPhone™ or iPods™ with 80 GB of storage. Release 7 of the 3GPP provides for a new approach in dealing with multimedia and large files by providing for a high-speed protocol based on USB technology. The new enhancements permit the UICC to be considered as a large and secure storage, including use of flash memory technology, an OMA smartcard web server, and enabling remote file management technologies.
Characteristics of Narrowband IoT (NB-IoT) technology that supports smart city management, based on the chosen use cases from the environment area
Published in Journal of Decision Systems, 2020
Narrowband IoT, also known as LTE Cat NB1, supports the latest 3GPP security. With the help of a physical SIM card connected to the device (UICC), they provide at the highest level authentication as well as data encryption and signalling protection. NB-IoT is cost-effective, supports lower power consumption for low-cost devices, and provides a wide range of coverage. This Low Power Wide Area Networks technology makes economies of scale an important theory for the IoT industry, connects virtually anywhere and works with already established cellular networks (Routray & Hussein, 2019). This technology is used to deploy a very high volume of low complexity, connected devices intended to transmit small data packages now and then. It affects smart cities, smart buildings and consumers.
