OMA Converged IP Messaging (CPM) V1.0

The CPM Enabler provides common building blocks, by reuse of existing blocks and by defining new ones, to allow for both the consolidation of present and the creation of future interpersonal interactive multimedia communication services which accommodate different user experiences such as deferred and Immediate Messaging, session-based messaging, and half duplex/full duplex conferencing.

CPM supports one-to-one, one-to-many personal communications, and also communication with Applications. CPM enables the creation of services that allow users to:

• communicate without knowing what network access technology is being used,
• have parallel conversations,
• personalise their services by setting preferences to indicate, for example, which device(s) messages should be sent to,
• store any type of message and Media in the network, and
• seamlessly make the transition from legacy voice, video and messaging services such as MMS and SMS to CPM based services by providing interworking between CPM and these legacy services.

The efficient use of resources (e.g. radio bandwidth) by all of CPM's features will be taken into consideration in the design of the CPM Enabler.
