Rapid Service Creation Environment for service delivery platform based on service templates

The requirement of quickly creating new value-added telecom services is increasingly becoming a business imperative today. Telecom operators and service providers are facing the challenge how to reduce cost and time-to-market of creating new services. The reduction is expected to be 1 or 2 orders of magnitude from months or weeks to days, even hours. In traditional Service Creation Environment, a full lifecycle of requirements analyzing, design, development, testing and deployment always has to be undergone. Such way of services creation always results in poor reuse of software assets and involves mass resources. Some technologies have been developed to speed up steps in this lifecycle, such as BPEL or SCXML. These orchestration techniques and tools are already used to reduce cost in design and development stages but the creation procedure still rely on attendance of IT specialists. This paper presents a way to shorten and simplify the whole service creation lifecycle and to reach the reduction target by building a template based Service Creation Environment. A model is used to separate service work flow definition and service parameters configuration and to achieve rapid development for different roles. A prototype of template based service creation environment is also introduced in this paper.

SIP network discovery by using SIP message probing

Currently more and more SIP based networks have been deployed in enterprises and communication carrierspsila domain to provide NGN services. With the widely adoption of SIP, information discovery in SIP network, which is the first step of SIP management, becomes a key challenge to operators and service providers. To address the problem, this paper presents an automated SIP network discovery approach based on SIP message probing. With our approach, minimal number of SIP request messages will be sent out to probe SIP entities and then targeted information could be obtained by wrapping and parsing the received responses. Experiment results show that the approach can effectively obtain SIP information for management while it costs limited probing messages.

Template based rapid service creation environment for service delivery platform

With the boom of telecom value-added services, operators and service providers have to face the challenge how to reduce the development cost and time to market of creating new services. Such reduction is expected to be 1 or 2 orders of magnitude from months or weeks to days, even hours. In traditional service creation environment, a full lifecycle of requirements analyzing, design, development, testing and deployment always has to be undergone. It is inevitable that mass resources including specialists and time are involved. Some technologies have been developed to speed up single steps, for example BPEL based orchestration technique and tools are already used to reduce the cost in design and development stages while the creation procedure is still rely on IT specialist. In this paper, we present an idea to shorten and simplify the whole service creation lifecycle to reach the reduction target by building a template based service creation environment. A model which separate process definition and service parameter are used to achieve rapid development and automatic deployment.

Asset-based requirement analysis in telecom Service Delivery Platform domain

Software product line engineering is an emerging software engineering paradigm which develops products or solutions based on domain assets. Domain requirements are core domain asset in software product line engineering, and requirement analysis for domain products or solutions based on domain requirements is a key step. Previous domain requirement models are suitable to model tens of variabilities in a domain which contains only a limited number of products. But in a solution domain such as SDP (service delivery platform) domain of telecom, there are thousands of variabilities among the solutions. In this paper, a new domain requirement model for solution domains is proposed. In this model, domain requirements are organized with three kinds of aggregation relationships and three kinds of generalization relationships. Based on these relationships, a configuration model is proposed to analyze the commonalities and variabilities among domain solutions. A solution requirement analysis method is also described based on the new domain requirement model. A case study is conducted on SDP domain which demonstrates how the proposed domain requirement model and solution requirement analysis method is used.

Common business process model for continuous SDP transformation

In the telecom industry, it becomes increasingly important for operators to provide a service delivery platform (SDP) quickly to improve time-to-revenue cycle of new innovative value-added services at lower cost. But the actual spectrum of services delivered by SDP is not yet clearly defined and differs from vendor to vendor. It will lead to the silo SDP problem. The SDP transformation solution intends to offer a horizontal SDP framework (metaSDP) which has the capability to work in concert with existing SDP silos. The common business process model (CBPM), which based on eTOM, is used to defined the general processed used in the metaSDP. To leverage the legacy carrierpsilas service platforms, the SDP specified processes are added into the eTOM with all level3 and level4 business elements, and modeled in IBM Websphere business modeler (WBM). The SDP business process instantiation method are also introduced here to describe how to create the service delivery processes quickly by this model and templates.

Service Differentiation for Business Process by Value Based Service Scheduling

Service differentiation is a practical approach for service provider to deliver ldquogoodrdquo service quality to different customers or customer segments under limited computing resources. In this paper, we address the problem of differentiating business process services by effectively scheduling tasks inside business processes, where dynamic value of service request, process instance execution status and workload of service components are all taken into consideration. Corresponding framework architecture and a scheduling algorithm are purposed for this purpose.
