A DLNA framework for NEXT GEN mobile terminals connecting IMS Networks for human-centered Digital Home Environment

In this paper, the author describes the design and implementation of a LDNA (Digtal Living Network Alliance) Framework for Handheld devices. DLNA has developed guidelines for interoperability among home devices enabling a multitude of usage scenarios for sharing digital content such as A V (Audio Visual), Photo, and Audio. The proposed DLNA (Digital Living Network Alliance) Client Framework handles multiple services like Video and multimedia services in Smart Home networks simultaneously. With this new DLNA framework, the home users can choose various services dynamically and use them with out any complicated pre-configuration with the Home IMS gateway (HIGA). The framework provides smooth data transfer switching in home network between Cellular and Wi-fi/Bluetooth networks to enhance mobility based on user/application preferences. The DLNA Framework also provides QoS measurement and monitoring functionality for multimedia services, which enables users to benefit from high throughput and maintains session continuity during selection of different access networks. Apart from these features, the DLNA Framework provides access to device access protocols like UPnP to facilitate the management of home devices.
