3.1 Definitions

For the purposes of this TS the following definitions apply:

applet: a small program that is intended not to be run on its own, but rather to be embedded inside another application.

application: USAT information in the form of software, applications, associated resources (e.g. libraries) and/or data.

bearer independent protocol: Mechanism at the interface between the USIM and the ME which provide access to the data bearers supported by the ME.

buffer: A dedicated memory used to temporarily store data to be sent and/or retrieved.

content: data and/or information associated with, or independent of, a particular application which may be presented to or collected from a user.

data channel: allow the USIM and the network to exchange data using a selected data exchange capability.

link: radio resource.

USAT service: a service enhanced (or made possible) by USAT technology.

USAT execution environment: the USAT execution environment provides the mechanisms to operate single or multiple USAT-applications.

USAT serving environment: an entity which delivers USAT services to the subscriber. This is normally the PLMN operator, but could be an entity with USAT responsibility (which may have been delegated by the PLMN operator).

USAT subscriber: the owner of a PLMN subscription who has entered into an agreement with a USAT serving environment for USAT services. Access to USAT services though other types of networks is out of scope of this specification.
