Enabling Ambient Aware Service Delivery in Heterogeneous Wireless Environments

With the development of novel access technologies e.g. LTE, WiMAX etc., the mobile devices are able to establish services over multiple wireless connections with different momentary capabilities. Being imported from the fixed line communication, the current services deployed are lacking an efficient mechanism of adaptation to the momentary connectivity conditions, which deters the efficiency of the service delivery. This paper introduces a novel solution for the adaptation of the services to the momentary network conditions of the mobile device which does not require a complete end-to-end re-signaling, by this reducing the communication over the wireless link and enabling efficient provisioning of the services and the development of new ones customized for the wireless environment. Furthermore, the concept is exemplified on the 3GPP Evolved Packet Core architecture and evaluated using the Fraunhofer OpenEPC testbed implementation.
