​Terms and Definitions  


3GPP - The 3rd Generation Partnership Project (3GPP) is collaboration among telecommunications associations known as the Organizational Partners. The initial scope of 3GPP was to make a globally applicable third-generation (3G) mobile phone system specification based on evolved Global System for Mobile Communications (GSM) specifications within the scope of the International Mobile Telecommunications-2000 project of the International Telecommunication Union. The scope was later enlarged to include the development and maintenance of:

       GSM and related 2G and 2.5G standards, including GPRS and EDGE

       UMTS and related 3G standards including HSPA

       Long Term Evolution and related 4G standards

       An evolved IMS developed in an access-independent manner

ABAC - Attribute-based access control defines an access control paradigm whereby access rights are granted to users through the use of policies that combine attributes together. The policies can use any type of attributes (e.g., user attributes, resource attributes, environment attributes).

Aggregation Network - A regional network that aggregates backhaul traffic toward regional data centers and national transmission networks.

AppContainer - The virtual machine construct also referred to as a sandbox, which creates an isolated security boundary around the application to keep its operation isolated from other applications and the operation system.
