MExE
Mobile Execution Environment
The Mobile Execution Environment provides a standardized execution environment in an MS (Mobile Station), and an ability to negotiate its supported capabilities with a MExE service provider, allowing applications to be developed independently of any MS platform. The MS can then be targeted at a range of implementations for MExE from small devices with low bandwidth, limited displays, low processor speeds, limited memory, etc., to sophisticated PDA (Personal Digital Organizer) type devices with a complete MExE execution environment.
