I am not sure to what extent implementing some functions in software (as opposed to embedding them in hardware) or implementing the service logic in a logically centralized controller instead of distributing it into the switches suggests that these functions are not needed or that separation of concerns is less relevant.
Earlier, Intelligent Networks introduced the concept of Service Control Point (SCP), a logically centralized node where the service logic is located, and communicating with the switches – known as Service Switching Points (SSPs) over the standard Signaling System 7 (SS7) protocol.
In our IPTV experiment, this is achieved by isolating the actual streaming server technology from the service logic.
In this paper, we present research efforts that attempt mainly to decouple context handling from the service logic.
Before elaborating on the Service Logic, we will introduce the process perspective on the EE and discuss the need for, and effect of, collaboration on EE performance.
Many SIP applications also require media handling, and from the functional perspective, these applications are made up of two entities, the service logic and the media-handling functions.
In this paper, we propose using insights from the marketing literature on the Service Logic (Grönroos 2006, 2008; Vargo and Lusch 2004) to develop a guiding logic for collective action in EEs.
After having introduced the Service Logic, we will discuss the usefulness of its value co-creation principle for integrating the process and structural perspective on EEs and the possible implications for organization design research and practice.
The usefulness of the Service Logic perspective lies in the inherent role of supplying organizations as facilitators of, and potential co-creators in, the customer's value creation process.
Accordingly, we present the design and implementation of a middleware infrastructure for ubiquitous computing services, which facilitates development of ubiquitous services, allowing the service developer to focus on the service logic rather than the middleware implementation.
