Mobile-to-mobile multi-user chat service framework for operator networks

In past few years, the concept of mobile servers has emerged dramatically. That means the mobile nodes have now gained such extraordinary processing powers and storage capacities that they can actively play a role of service delivery platforms in the service oriented paradigms. Recently, a concept of Mobile Application Servers (Mob-ASs) has been introduced by the research community in order to promote M2M (Mobile-to-Mobile) service networks over the telecom operator networks. Such joint-venture of IT and Telco systems will bring a plethora of new M2M applications in the market. This paper presents the design and evaluation of an M2M chat service framework for an existing Mobile Server Platform (MSP). The existing MSP has the capacity to register itself as a Mobile Application Server (Mob-AS) and a Mobile Application Client (Mob-AC) in the operator´s IMS (IP Multimedia Subsystem) network. Featuring the MSP with the chat service framework will facilitate the mobile users to exchange short and long text messages and multimedia files over the operator network without using any third-party services.
