A framework for abstracting complexities in service delivery platforms

The telecommunication (telco) and Information Technology (IT) industries are converging into a single highly competitive market, where service diversity is the critical success factor. To provide diverse services, the telco network operator must evolve the traditional voice service centric network into a generic service centric network. An appropriate, but incomplete, architecture for this purpose is the Service Delivery Platform (SDP). The SDP represents an IT-based system that simplifies access to telco capabilities using services. SDP services offer technology independent interfaces to external entities. The SDP has vendor-specific interpretations that mix standards-based and proprietary interfaces to satisfy specific requirements. In addition, SDP architectural representations are technology-specific. To be widely adopted the SDP must provide standardised interfaces. This work contributes toward SDP standardisation by defining a technology independent and extendable architecture, called the SDP Framework. To define the framework we first describe telecom-IT convergence and a strategy to manage infrastructure integration. Second, we provide background on the SDP and its current limitations. Third, we treat the SDP as a complex system and determine a viewpoint methodology to define its framework. Fourth, we apply viewpoints by extracting concepts and abstractions from various standard-based telecom and IT technologies: the Intelligent Network (IN), Telecommunication Information Networking Architecture (TINA), Parlay, enhanced Telecommunications Operations Map (eTOM), Service Oriented Architecture (SOA) and Internet Protocol Multimedia Subsystem (IMS). Fifth, by extending the concepts and abstractions we define the SDP framework. The framework is based on a generic business model and reference model. The business model shows relationships between SDP, telco and external entities using business relationships points. The reference model extends the business model by formalising relationships as reference points. Reference points expand into interfaces exposed by services. Applications orchestrate service functions via their interfaces. Service and application distribution is abstracted by middleware that operates across business model domains. Services, interfaces, applications and middleware are managed in Generic Service Oriented Architectures (GSOA). Multiple layered GSOAs structure the SDP framework. Last, we implement the SDP framework using standard-based technologies with open service interfaces. The implementation proves framework concepts, promotes SDP standardisation and identifies research areas

The objective, as initially stated, is to "provide a venue where: the cost of participation was minimum; participants were able to attend various workshops, so fostering collaboration and cross-fertilization; there was a friendly atmosphere and plenty of time for networking, by maximizing the time participants spent together"

Orthographic practices in SMS text messaging as a case signifying diachronic change in linguistic and semiotic resources

From 1998, SMS text messaging diffused in the UK from an innovation associated with a small minority, mainly adolescents, to a method of written communication practised routinely by people of all ages and social profiles. From its earliest use, and continuing to the time of writing in 2015, SMS texting has attracted strong evaluation in public sphere commentary, often focused on its spelling. This thesis presents analysis of SMS orthographic choice as practised by a sample of adolescents and young adults in England, with data collected between 2000 and 2012. A threelevel analytical framework attends to the textual evidence of SMS orthographic practices in situated use; respondents’ accounts of their choices of spelling in text messaging as a literacy practice; and the metadiscursive evaluation of text messaging spelling in situated interaction and in the public sphere. I present analysis of a variety of representations of SMS orthographic choice, including facsimile texts, electronic corpus data, questionnaire survey responses and transcripts of recorded interviews. This mixed methods empirical approach enables a cross-verified, longitudinal perspective on respondents’ practices, and on the wider significance of SMS orthographic choice, as expressed in private and public commentary. I argue that the spelling used in SMS exemplifies features, patterns, and behaviours, which are found in other forms of digitally-mediated interaction, and in previous and concurrent vernacular literacy practices. I present SMS text messaging as one of the intertextually-related forms of self-published written interaction which mark a diachronic shift towards re-regulated forms of orthographic convention, so disrupting attitudes to standard English spelling. I consider some implications represented by SMS spelling choice for the future of written conventions in standardised English, and for teaching and learning about spelling and literacy in formal educational settings
