Abstract: A component-based control application structure for the dynamic configuration, adaptation and extension of applications in wireless communication is presented. Thereby, a control application (304) for technical elements (301) of a mobile communications device (101a, 101b) is structured in components of a predetermined configuration (305), wherein the configuration (305) depends on the task to be performed. Each component (401) is provided with its own thread (404). Each component (401) is furthermore provided with a method interface (403) comprising different commands for the control of the operation of the respective component (401). The configuration (305) of the control application (304) can be changed dynamically (203) depending on the current task to be performed by the device.

Abstract: The present invention relates to a system that enables the nearly real-time transmission of messages originated and received from/by heterogeneous communication networks. The purpose of instant messaging is to transmit high priority messages in (nearly) real-time between clients (man and machine). Unified messaging merges analog and digital transmitted messages such as facsimile, voice mail, e-mail, WWW and the cell phone short message service (GSM/SMS) to unified instant messages. A Unified Instant Messaging System (UIMS) consists of four major components: distributed gateways, message brokers, message processors and a client directory database. Messages of arbitrary form can be translated into Unified Instant Messages (UIM) by Instant Message Gateways (IMGateways). Instant Message Brokers (IMBrokers) control the message flow and further message processing. IMBrokers also ensure message authenticity and security.
