Web services and multimedia in m‐business applications: Opportunities and concerns

Web services refer to a specific set of technologies used to implement a Service Oriented Architecture. Thanks to maturing Web‐services standards, and to new mobile devices and application solutions, progress is being made in presenting similar Web‐services offerings in both mobile and fixed networks. To bring that architecture and the solutions it will support to the world of mobility is indeed a significant issue in m‐business applications, because mobile Web services present various advantages: Reduction of the overall cost of development (by reusing existing system components), faster time to market introduction of products (provided by applications’ rapid development and deployment) and remarkable possibilities to emerge new applications with increased functionalities. In addition, the new and forthcoming mobile networks, with native IP connection and high speed transmission capability, allow the development of a variety of modern multimedia services. Multimedia Messaging Services (capable to mix the media types in order to enable more intuitive messaging operation), and Instant Messaging and Presence Services (dedicated for presence, instant messaging, and distribution and sharing of multimedia content in groups of users), provide suitable underlying capabilities to support location‐based and context‐sensitive multimedia services. In this paper we will present the current approaches regarding architectural, functional and security features that allow enterprises to enjoy the benefits of traditional Web services in the mobile multimedia domain.
