MExE provides a standardised execution environment in an UE, and an ability to negotiate its supported capabilities
with a MExE service provider, allowing applications to be developed independently of any UE platform. The UE
(consisting of the ME and SIM/USIM) can then be targeted at a range of implementations for MExE from small devices
with low bandwidth, limited displays, low processor speeds, limited memory, MMI etc., to sophisticated with a
complete MExE execution environment.
The scope of this TS encompasses the MExE functionality in the UE, and the interaction with the MExE service environment. The MExE service environment is not necessarily restricted to the PLMN, and nodes providing MExE services (i.e. MExE servers) may also exist outside the PLMN. Aspects of the support provided by MExE servers within the MExE service environment (such as charging aspects, security level classification etc.) are covered by this TS, but not the MExE servers themselves.
