Mobile Station Application Execution Environment (MExE) Service description Stage 1
This ETSI Technical Specification defines the stage one description of the Mobile Station Application Execution Environment (MExE). Stage one is an overall service description, primarily from the subscriber’s and service providers’ points of view, and does not deal with the details of the human interface itself.
This TS includes information applicable to network operators, service providers and terminal, switch and database manufacturers.
This TS contains the core requirements for a Mobile Station Application Execution Environment (MExE) which are sufficient to provide a complete service.
It is highly desirable however, that technical solutions for a Mobile Station Application Execution Environment (MExE) should be sufficiently flexible to allow for possible enhancements. Additional functionalities not documented in this TS may implement requirements which are considered outside the scope of this TS. This additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users. Such additional functionality shall not compromise conformance to the core requirements of the service.
Figure 1: Scope of this TS
As indicated in Figure 1, the scope of this TS encompasses the MExE functionality in the MS, 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 specification, but not the MExE servers themselves.
MExE requirements are considered to be applicable to both GSM and UMTS systems.
