“…This article extends the work presented in Cabral Pinto, Videira, Carapeto, and Dinis (2010) by enhancing the devised framework towards an architecture capable of an effective context-aware multimedia content distribution to users groups, opening the doors to Mobile Operators, allowing them entry in the Social Networks world. It is here defended the association between context, E-MBMS and IMS systems enabling suitable multimedia sharing within mobile communities on Next Generation Networks.…”

The work here presented introduces a next generation context-aware architecture for social networking multimedia distribution. It enhances the Multimedia Broadcast Multicast Service (MBMS) and the Evolved MBMS (E-MBMS) systems by adding users' situation knowledge on their assessments allowing Mobile Operators to offer personalized services delivered over optimized networks. Furthermore, it evolves IP Multimedia Subsystem (IMS) with specific functionalities to control the context information and to manage MBMS and E-MBMS bearers. The proposed framework was tested and the results are here presented. A clever content sharing in mobile communities can be the basis of the famous killer application that Mobile Operators are still looking for.

“…The context of the users' routine is derived by tracking their location and monitoring their (next) daily schedule. Pinto et al (2012) proposed a context-aware architecture to capture context information of users and to control multimedia channels (e.g. unicast, multicast or broadcast channels) for message delivery.…”

Hazard-intense applications of cyber-physical systems (CPSs) such as the evacuation of a building on fire requires optimal management of stakeholders. Personalized message generation and informing of stakeholders based on real-time assessment of the dynamic context of stakeholders is the research and engineering challenge addressed by this paper. Personalized multi-message construction mechanism (MCM) that is enabled by dynamic context modeling, inferring and reasoning is proposed. Dynamic personal context was defined as the total of space-and time-varying situations that are relevant to a stakeholder. The basis of generating messages is a quantitative evaluation of the implications of the relevant situations with regards to the target stakeholders. The concept of impact indicator was used to represent the implications of situations and a personal danger level indicator was used to choose a proper message template for message construction. The algorithms included in the MCM were validated in a (simulated) indoor fire evacuation guiding application. Test people were involved in the practical evaluation of the quality of the generated messages. The conclusion is that the proposed MCM provides more sufficient information about personal context and expected actions than the messages constructed based on static context information.

The growing popularity of multimedia group communications requires evolved networking technologies to provide rich-media content to groups of users in the most effective way. 3GPP (3rd Generation Partnership Project) has specified MBMS (Multimedia Broadcast Multicast Service) to enable broadcasting and multicasting packet data in UMTS (Universal Mobile Telecommunication System) networks to large user groups. Furthermore, the LTE/SAE (Long Term Evolution / Service Architecture Evolution) specification has evolved MBMS in order to provide broadcast connections over the EPS (Evolved Packet System) architecture. Context, understood as any information that modifies over time, can be used to improve systems' efficiency. Mobile Operators already use location-based information to deliver more accurate content to their clients. But context may have an emphasized role when dealing with communications' groups. Context information shall be used to increase the system effectiveness while augmenting the user experience. This paper introduces the required evolutions towards an architecture where context information is taken into account to improve MBMS and E-MBMS (Evolved MBMS) services allowing an effective multimedia content delivery to mobile users' communities. But are the clients willing to let Mobile Operators know everything about them even if this knowledge is used to meet their needs? Are we ready to have a Big Brother Mobile Network which is always watching us?
