Abstract:
Business communication should become more effective through Unified Communications (UC) solutions. With UC, communication services such as telephony, video conferencing, presence, chat, file sharing, etc. become available independent of location or end device. Seamless mobility - the possibility of remaining connected on a mobile device while the connection is being handed off between different networks - is the most important technical factor in efficient mobile communication, especially in the field of UC telephony, which uses both conventional mobile and Internet Protocol (IP) networks for voice calls. Unforeseeable external influences on the quality of service (QoS) and unforeseeable operating conditions of the mobile technology frequently result in connection disruptions. This wastes the user’s time and energy and results in a poor performance rating. Based on the example of a mobile UC solution, this paper presents the requirements placed on mobile UC telephony. The QoS barriers, user expectations, and principles for the design of QoS-sensitive interaction are summarized. An example is provided of how the UC-telephony user’s quality of experience (QoE) can be increased on the basis of a Handover Convenience Information Support (HOCIS) by means of implementing QoS-sensitive user interaction.
